Chain joint assembling method

Abstract

A chain joint assembling method includes step 1, providing a working rotary table; step 2, conveying pins; step 3, feeding outer links and assembling the same; step 4, primary round riveting; step 5, secondary round riveting. In the step 1, the working rotary table is connected with a driving device, 12 pairs of grooves are arranged on the outer side of the working rotary table uniformly, the driving device drives the working rotary table to rotate intermittently, and the rotation angle each time is 30 degrees. In the step 2, two pins are pushed into a first pair of grooves; In the step 3, the working rotary table rotates twice to push the links to the pins, the links are then assembled, and parts of the pins are protruded from the links. In the step 4, the working rotary table rotates three times continuously so that one of the pins with the links in the previous steps is subjected to round riveting. In the step 5, the working rotary table continues to rotate three times so that the other pin is subjected to round riveting. By the chain joint assembling method, reliability and action synchronism during production can be improved, loss in production is avoided, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of chain production, in particular to a PLC-controlled chain joint assembly method. Background technique [0002] In the field of chain production, after the assembled chain has undergone processes such as riveting, oiling, and cutting, it is a section of chain. Connect, and then clamp the movable joint with a spring card to form a complete chain. [0003] Usually, the production of this movable joint is completed by manual assembly and riveting, the production efficiency is extremely low, and because the manual operation has different mastery of proficiency, the quality is very unstable, and the risk of manual assembly and riveting is very high. When assembling and riveting, if you don’t pay attention to it, you will cause damage to yourself. Therefore, in the current assembly and riveting production, injury accidents occur from time to time, which will not only affect the normal production and operation of the ente...

Problems solved by technology

[0003] Usually, the production of this movable joint is completed by manual assembly and riveting, the production efficiency is extremely low, and because the manual operation has different mastery of proficiency, the quality is very unstable, and the risk of manual assembly and riveting is very high. When assembling and riveting, if you don’t pay attention to it, you will cause damage to yourself. Therefore, in the current assembly and riveting production, injury accidents occur from time to time, which will not only affect the normal production and operation of the enterprise, but also cause personal injury to the operator. And the work-related injuries caused, and its follow-up expenditure is also a big hidden danger to the enterprise.
