When we grind the processing solutions for keyrobot componentson a daily basis, the manufacturing of robot connecting rod frames is always the essential difficulty that cannot be avoided.

These types of components can be named "bones" of the robots, and clients have very particular requirements on them: they must be strong (sufficient rigidity), highly precise in respect to size (high accuracy), and as light as possible, so the robot can move with less energy and faster.

To achieve these seemingly contradictory goals, high performance CNC machining is our strong point for certain. It's as precise as a surgical scalpel, rendering each machined connecting rod frame robust, precise, and dependable by stable cutting, rigorous tolerance control, and structural optimization design,which is the foundation for the smooth and accurate running of the entire robot mechanism.

Our JS team has been working hard here for many years, focusing on providing this highlycustomized CNC machiningmanufacturing. Faced with these stringent standards in the industry, we understand the pain points and have real capabilities to match and exceed these high requirements with reliable processing technology.

Core Answer Summary:

Detailed Explanation Of Parts: Design Features And Functions Of The Robot Link Frame

Geometric design: Modular skeleton

The link frame we designed is like the skeleton of the robot, full of precise installation holes. This porous + high-opening structure is not opened randomly. It allows motors, sensors and other components to be assembled flexibly like Lego, andit is also more convenient to maintain and replace parts later.

The secret of lightweight: only keep the parts that should be kept

On the premise of ensuring strength, we usetopological optimizationtechnology to "hollow out" the non-load-bearing parts. It is like making precise "slimming" for parts, and the final weight reduction can reach 30%. Don't underestimate this weight, the whole machine's movement speed and energy consumption performance depend on it.

Material selection: toughness is the hard truth

For this type of key parts, we prefer aviation-grade 7075 aluminum alloy or titanium alloy. Just like the logic of material selection for F1 racing chassis: the strength per unit weight must be full. After heat treatment, the tensile strength exceeds 550MPa, which is equivalent to an area the size of a fingernail that can lift an adult bull.

Processing difficulty: "Dancing" on the tip of the tool

• Hole position accuracy: The position error of 120+ mounting holes must be controlled within ±0.02mm (1/4 thinner than a hair).
• Surface processing: Special-shaped contours requirefive-axis linkage processing,which is like "carving" metal with a machine tool.
• Deformation control: Thin-walled structures are prone to vibration duringprocessing and require special tooling solutions.

As the precision manufacturing master Joseph Whitworth said: "Measurement accuracy is manufacturing accuracy", each micron-level tolerance of this type of CNC machining parts directly determines the life of the entire robot.

JS's CNC Machining Service Advantages

Online customization: Drawings are transmitted in seconds, and quotations are available immediately

We have opened up the entire process of online CNC machining services. After you upload the3D drawing, the system automatically analyzes the structural features (hole position/surface/material) and feedbacks the accurate CNC machining price within 2 hours. Save the trouble of repeated email confirmation. Compared with the cumbersome process of traditional manufacturers, the advantages are obvious:

Note: The benchmark quotation is based on the 7075 aluminum alloy connecting rod frame (200×150×50mm).

Accuracy guarantee: five-axis connection, strict micron-level accuracy control

The connecting rod core is processed bythe German DMG five-axis machine tool.At the time of simultaneous cutting of multiple holes, position accuracy is ensured to ±0.01mm (equal to the diameter of human red blood cells), so each bearing hole can be tightly connected to the transmission mechanism, the inherent secret of the robot's smooth motion.

Flexible mass production: 10 to 10,000 pieces controllable

Fromprototype verificationto batch delivery, we provide real custom CNC machining manufacturing. Small batches utilize flexible manufacturing lines (5 pieces min order), large batches start exclusive workshops, andequipment debugging time reduces by 70%when shifting orders, so that production capacity will never be your bottleneck.

Quality closed loop: triple detection for performance guarantee

• The first three-coordinate machine checks 132 key dimensions (accuracy 1.5μm) and generates a 3D deviation chromatogram.
• During manufacturing, laser monitors tool wear in real-time. Laser probe stimulates after checking 20 parts to program the tool. If wear is more than 0.03mm, the machine halts automatically and replaces the tool.
• Stress is released in a constant temperature environment 36 hours before delivery.
• The quality control system is built with reference to theaerospace AS9100 standard, so that each part meets the standard when it leaves the factory.

Industry Application Background

What I usually deal with most are the "inconspicuous" but crucial core components in the robot. Today I want to talk to you about a key component we have been deeply involved in - the core connection frame, the role it plays in the robot world, and the trends we see.

The core Connection frame: A key determinant of motion accuracy and load-bearing capacity

Imagine the robot joints. The middle connecting frame we built serves as the basis for the tight integration of different segments in a robot arm and drive assemblies.

There are two most direct effects:

• one is that it has a direct bearing on the motion accuracy of the robot arm.
• And the other is the maximum load capacity.

If the frame itself is too weak, not rigid enough, or lacking components in the attachment, no matter how good the algorithm and motor are, it will be useless, causing reduced accuracy or compromised load capacity. Therefore, it is no exaggeration to say it is the "bones and muscles" of the robot.Only if the bones and muscles are solid can the robot show its strength.

Wide application scenarios: Supporting diverse robot needs

(1) Robot arms in factories:

This is the most common. Whether it is large equipment for precise welding and assembly in automobile factories, or manipulators that quickly grab small parts in electronics factories, their joints and base connections require our high-rigidity, high-precision connection frames to ensure repeated positioning accuracy and stable work without falling apart.

(2) Self-run logistics robots/AMRs:

These mobile robots often carry lifting or grabbing robotic arms. The connection frame here must be both lightweight and strong enough to ensure that the arm will not shake or deform during movement or lifting of goods, affecting the accuracy of picking and placing.

(3) Surgical robots that assist doctors:

This requires the highest precision and reliability. The connection frame is in the surgical arm, and it must ensure that the doctor's tiny movements can be accurately transmitted to the end of thesurgical instrument. The slightest deformation or gap may bring risks, so the requirements for CNC machining materials and processing are extremely demanding.

Performance improvement drives continuous optimization of processing accuracy

The broadening of the scope of robot application fields and the ongoing enhancement of performance demands imposed "near-abnormal" requirements on the connection frame. Customer voices are extremely straightforward: Too little accuracy? No! Too little strength? Even worse!This calls for us to keep enhancingprocessing accuracy.

Each contact surface, hole, and thread on the frame will have its processing fault enhanced, which will, in turn, affect the entire robot's performance. Much effort has been put into the optimization of the processing technology and elevating the inspecting standards to ensure each connector manufactured goes out to be able to fit closely, hard, and reliable, and can become a trustworthy base for improving the overall performance of the robot.

"Although the core connection frame is small, it is the key cornerstone for the robot to be flexible, accurate, stable and reliable. From factory automation to medical innovation, its performance directly affects the final effect. At JS, we are well aware of this and continue to refine our processes to provide connection solutions with higher precision and stronger performance. Want to take your robot to the next level? Why not talk to us and build a stronger "bones" together!"

Success Story: Building "Stronger And Lighter" Connection Skeleton Parts For Top Industrial Robot Partners

Today, I would like to present you to a real project which we are pleased with, and see how the high-precision processing of the main connection frame is directly helping customers achieve success.

Project background:One of the world-leading manufacturers of industrial robots found us, and they are now making a new generation of high-speed, high-precision robotic arms.

The major challenge is in the central connecting frame of the robot arm: it needs to minimize weight but bring ultra-high strength (bear gigantic loads and shocks), and the structure is extremely complex with all kinds of different high-precision holes and strict assembly interfaces, and the tolerance requirements are extremely stringent.

JS's solution: precision manufacturing + agile response

• Material selection:We unambiguouslychoose aviation-grade high-strength aluminum alloy.This is equivalent to choosing the top-of-the-range light alloy for the skeleton, exactly balancing the opposing needs of "strong" and "light.".
• Precision machining:The highlight of the equipment is the five-axis linkageCNC machining center. It can accurately complete all the hard hole machining and complex surface fine grinding on the frame simultaneously (so that it will be in assembly and stress distribute properly) like the most experienced hand.
• Speed ​​and agility:Customer design iteration is fast? No problem! We have established an intelligent online quotation system that can quickly respond to design change, making flexible adjustments to processing technology and scheduling, and greatly minimizing communication and preparation time.
• Iron law of quality:Quality is the lifeline. We possess an extremely rigorous full-process inspection procedure and utilize precision three-coordinate measuring machines and other equipment to ensure that the dimensional stability of all key holes and assembly surfaces is tightly regulated at ±0.02mm, which is muchmore severe than the usual industry standards.
