Abstract

The invention discloses a pressing spiral formation process for a belt pulley, and belongs to the technical field of robot transmission part processing methods. The pressing spiral formation process for the belt pulley comprises the following steps: dropping a material, forming a central overflowing hole, performing pressing spiral formation, performing primary spiral pressing drawing, performing secondary spiral pressing drawing, performing side turning, performing lateral side thickening formation and performing lateral side tooth-shaped formation. Compared with the prior art, the pressing spiral formation process has the advantages that a novel process of 'pressing spiral'formation is invented, and a novel process for a robot joint speed reducer transmission part matching area formation is provided; the transmission freedom degree is increased, conventional transmission is achieved in a shaft pin transmission manner, a shaft cannot be separated from the belt pulley, and by adopting the pressing spiral formation process, the belt pulley can be separated and combined with a matching transmission part in transmission, and thus the robot can act relatively flexibly; and in a whole belt pulley plasticity formation process, the belt pulley of a robot joint speed reducer is formed in a spiral pressing manner completely, so that the production efficiency is effectively improved, and integral formation of the belt pulley transmission part can be achieved.

Description

technical field [0001] The invention relates to the technical field of machining methods for robot parts, in particular to a press-spin forming process for a pulley. Background technique [0002] At present, the belt pulleys for small robot joint reducers are usually connected to the shaft through a flat key. Although this connection method is convenient to process, due to the tight fit and the long-term work of the belt pulley, the matching surface of the shaft hole is prone to corrosion, so it needs to be replaced. It is difficult to disassemble with a puller or hammer, and it is easy to damage the pulley, and in severe cases, the shaft will be bent and deformed. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a press-spin forming process for the pulley, in order to improve the defects in the prior art such as difficult disassembly of the pulley, easy damage of the pulley and shaft, infl...
