Electrode cap changing tool

Abstract

This utility model provides an electrode cap changing tool, including a fixed base and a pressing handle. A rotating shaft is provided on the fixed base, and one end of the pressing handle is mounted on the rotating shaft and rotates along it. A through groove is provided on the fixed base, the shape of which matches the electrode cap. A positioning pin is provided on the pressing handle, positioned above the through groove. The electrode cap is fixed by the through groove, and simultaneously, the positioning pin on the pressing handle presses down on the electrode cap, allowing it to be removed. This improves work efficiency and protects the electrode cap and other parts, preventing accidental injury. A limiting stop further enhances safety by protecting the welding clamp. The longitudinal through groove also allows for the disassembly of electrode caps with special structures, increasing the applicability of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to an electrode cap replacement tool. Background Technology

[0002] Currently, during welding operation, the welding electrode needs maintenance for various reasons. The protective cap on the electrode post, as both an exposed and protective component, is crucial to its integrity. However, because the protective cap is installed very tightly, tools are required to remove it. Currently, removing the electrode cap typically requires pliers, which is time-consuming, laborious, and easily damages other parts of the welding clamp. Therefore, designing a tool for removing electrode caps is an important task for those skilled in the art. For example, published patent 2023101104632 discloses an electrode cap removal device. With this technical solution, when removing the electrode cap, the electrode cap body is first placed into the receiving tube from the open end, with the electrode cap and the welding equipment connection section positioned within the clearance groove and the first removal groove. The electrode cap is then manually pressed and rotated to remove it, allowing the removed electrode cap to fall into the receiving tube. The electrode cap removal device disclosed herein combines removal and storage functions, effectively preventing operators from dropping the electrode cap into the production line during removal, thus ensuring good safety. However, the aforementioned structure can easily damage other components during disassembly, leading to a reduction in the overall lifespan of the welding clamp. Therefore, addressing the issue of damage to the welding clamp during electrode cap removal is particularly important. Utility Model Content

[0003] The purpose of this utility model is to provide an electrode cap replacement tool. The electrode cap is fixed by a through groove, and the electrode cap is squeezed by pressing down the positioning pin on the handle to remove the electrode cap. This improves work efficiency, protects the electrode cap and other parts, avoids accidental injury, and solves the problem of easy damage to the welding clamp during electrode cap removal.

[0004] This utility model provides an electrode cap replacement tool, including a fixed base and a pressing handle. The fixed base is provided with a rotating shaft, one end of the pressing handle is mounted on the rotating shaft and rotates along the rotating shaft, the fixed base is provided with a through groove, the shape of the through groove is consistent with the electrode cap, and the pressing handle is provided with a positioning pin, the positioning pin being positioned above the through groove.

[0005] A further improvement is that a force sensor is installed on the positioning pin. The force sensor detects the reaction force on the positioning pin and determines whether the electrode cap needs to be removed.

[0006] A further improvement is that a limit stop is provided on the fixed seat at the front of the rotating shaft, which limits the lifting angle of the pressing handle.

[0007] A further improvement is that the mounting base is provided with a hanging hole, which is located next to the through slot for suspending the tool.

[0008] A further improvement is that the handle of the pressing handle is a telescopic handle, and the handle of the pressing handle is provided with a boss and an adjustment hole, so that the length of the handle can be adjusted by changing the position of the boss in different adjustment holes.

[0009] A further improvement is that a longitudinal through-slot is also provided next to the through-slot, which is used for special operations.

[0010] The advantages of this utility model are as follows: the electrode cap is fixed by the through groove, and the electrode cap is squeezed by the positioning pin on the downward handle to remove the electrode cap, which improves work efficiency and protects the safety of the electrode cap and other parts to avoid accidental injury. At the same time, the limit block improves safety and protects the welding clamp. The longitudinal through groove is set to disassemble the electrode cap with special structure, which increases the applicability of the equipment. Attached Figure Description
