Abstract

The invention relates to a load balancing method of movement joints in the vertical direction of a robot. Air cylinders are adopted for balancing load in the gravity direction of the robot, air pressure in the air cylinders can be flexibly regulated according to the size of the load, and the purpose of assisting in driving of the joints of the robot is achieved. Large-volume pressure-resistant energy accumulators are adopted for guaranteeing the constant air pressure in a starting system, and stability of the system is enhanced. Compared with the prior art, the method is capable of effectively balancing the load gravity in the gazing direction, is capable of effectively lowering type selecting power of driving components, saves cost, and improves reliability.

Description

Technical field [0001] The invention relates to a robot counterweight method based on a pneumatic accumulator. The method is particularly suitable for vertical movement of high speed and large load in the vertical direction. The thrust action of a pneumatic cylinder is used to balance and increase the load gravity. To achieve the purpose of using a smaller drive motor to drive a larger load at high speed. Background technique [0002] With the improvement of industry requirements for product appearance and surface quality, polishing is often used in the finishing process of products. Especially for the polishing of complex curved surfaces, such as high-end plumbing components, stationery, aero-engine blades, water turbine blades, etc., generally only manual operations can be used, which is time-consuming and labor-intensive, low efficiency, and poor product consistency and accuracy. The CNC polishing system such as the robot polishing system uses programming control to realize a...
