Description

Technical Field

[0002] Resistance welding is a widely used welding technique for joining metal materials. It achieves this by generating resistance heat when an electric current passes through the workpiece. During the resistance welding process, the electrode cap, a crucial component of the welding electrode, directly contacts the workpiece, transmitting current and pressure, and thus directly impacting weld quality. However, during resistance welding, the electrode cap gradually deteriorates due to high temperatures, high pressures, and wear of the cap material. Regular replacement is required to maintain weld quality, necessitating the use of a resistance welding electrode cap removal device.

[0003] However, the existing resistance welding electrode cap removal device still has certain defects. For example, when faced with some difficult-to-remove electrode caps, the operator needs to use greater force than usual to remove the electrode cap, which is inconvenient and affects work efficiency. Secondly, although a removal tool with a longer lever arm can be used, the space occupied by the longer removal tool during storage will also increase, which lacks practicality.

[0029] Adjustment assembly 9, the adjustment assembly 9 includes a fixed seat 10, a fixed rod 11, a flip seat 12, an arc-shaped plug 13, a second spring 14 and a T-shaped handle 15. The inner surface of the fixed seat 10 is fixedly connected to the fixed rod 11, the lower surface of the flip seat 12 is fixedly connected to the arc-shaped plug 13, the lower surface of the flip seat 12 is fixedly connected to the second spring 14, the outer surface of the flip seat 12 is fixedly connected to the T-shaped handle 15, the inner surface of the arc-shaped socket 16 is adapted to the arc-shaped plug 13, the upper surface of the sleeve 7 is fixedly connected to the fixed seat 10, the outer surface of the fixed rod 11 is rotatably connected to the flip seat 12, the outer surface of the arc-shaped plug 13 is slidably connected to the sleeve 7, and the lower end of the second spring 14 is fixedly connected to the sleeve 7.

[0030] Working principle: When in use, put the through hole 18 on the electrode cap, and then drive the connecting rod 4 through the sheath 17 to drive the interference block 1 to cooperate with the fixed column 2 to flip. When the first tooth block 19 inside the through hole 18 and the second tooth block 20 on the outer surface of the interference block 1 clamp the electrode cap, continue to flip the connecting rod 4 as a whole to loosen or tighten the electrode cap. When the electrode cap is difficult to disassemble, press the T-shaped handle 15 on the adjustment component 9 to drive the flip seat 12 to drive the arc plug 13 to flip around the fixed rod 11, and compress the second spring 14 to disengage the arc plug 13 from the corresponding arc plug 16. Then verify that the guide rod 8 pulls the sleeve 7 outward through the limit block 5 to make the connecting rod 4 inside the sleeve 7 extend. And stretch the first spring 6, and then when the length of the connecting rod 4 is sufficient, loosen the T-shaped handle 15, and under the action of the restoring force of the second spring 14, the arc-shaped plug 13 will automatically snap into the corresponding arc-shaped socket 16, thereby temporarily fixing the length of the force arm of the device, and then the increase in the length of the force arm can increase the torque when removing the electrode cap, so that the operator can use less force to remove the tighter electrode cap, thereby improving work efficiency. When the entire device needs to be stored, just press the T-shaped handle 15 again to drive the arc-shaped plug 13 out of the inside of the arc-shaped socket 16. At this time, under the action of the rebound force of the first spring 6, the connecting rod 4 will automatically retract into the inside of the sleeve 7 to reduce the space occupied by the entire device and improve practicality.
