Description

Technical Field

[0001] The utility model relates to the technical field of disassembly tools, in particular to a self-locking pin removal tool. Background Art

[0002] In modern manufacturing and assembly processes, welding flexible fixtures are widely used to position and clamp various workpieces. These fixtures usually use locking pins to achieve fast and precise workpiece fixation. However, in actual applications, locking pins are exposed to welding environments for long periods of time and are affected by multiple factors such as high temperature, spattering welding slag, and humidity, causing rust and scale on the pin surface. Over time, these rust and scale will gradually accumulate, making it extremely difficult to remove the locking pin when it needs to be removed.

[0003] Even if the operator completely twists the locking knob out, the pin often cannot fall off by itself due to rust and stagnation. This not only increases the difficulty of disassembly, but also prolongs the time to replace the fixture or adjust the workpiece position, thereby reducing production efficiency. What is more serious is that excessive force or improper disassembly methods may cause damage to the locking pin or fixture table, increasing maintenance costs and safety risks.
