A connecting rod 4 is fixedly installed at the bottom of the moving end of the welding robot 1 and threadedly connected to the top of the welding torch body 2. A clamping assembly 5 is movably installed on the surface of the moving end of the welding robot 1.

[0022] refer to Figure 2The clamping assembly 5 includes an adjustment knob 51, a bidirectional screw 52, ​​a clamping plate 53, and a limiting rod 54. The adjustment knob 51 is movably mounted on the right side of the moving end of the welding robot 1. The bidirectional screw 52 is fixedly mounted on the left side of the adjustment knob 51. The other end of the bidirectional screw 52 passes through the moving end of the welding robot 1 from right to left and extends to the left side of the moving end of the welding robot 1. The clamping plate 53 is threadedly connected to the surface of the bidirectional screw 52 and is located on the left and right sides of the moving end of the welding robot 1. The limiting rod 54 is fixedly mounted on the left and right sides of the moving end of the welding robot 1. The other end of the limiting rod 54 passes through the clamping plate 53 from the inside to the outside.

[0023] As a technical optimization of this utility model, the clamping component 5 is set on the outside of the moving end of the welding robot 1. The adjustment knob 51 is rotated to drive the bidirectional screw 52 to rotate. The bidirectional screw 52 rotates and drives the clamping plate 53 to move. The clamping plate 53 clamps the welding gun body 2. When the clamping plate 53 moves, the limiting rod 54 cooperates to limit the movement of the clamping plate 53.

[0024] refer to Figure 3 The welding torch body 2 has a movable groove 6 inside, and a movable groove 7 is opened on the front of the welding torch body 2 and is connected to the movable groove 6. A movable sleeve 8 is movably installed inside the movable groove 6, and a movable rod 9 is movably installed inside the movable groove 7 and is fixedly connected to the front of the movable sleeve 8.

[0025] As a technical optimization of this utility model, the movable sleeve is installed in the movable groove 6 inside the welding torch body 2, and the movable rod 9 is installed in the movable groove 7 through the movable groove 6. The movable rod 9 drives the movable sleeve 8 to perform adjustment work inside the movable groove 7.

[0026] refer to Figure 3 The top of the movable sleeve 8 is provided with a slot 10, and the bottom of the connecting rod 4 is fixedly installed with two sets of locking blocks 11. The bottom of the two sets of locking blocks 11 engages with the slot 10.

[0027] As a technical optimization of this utility model, the slot 10 set on the top of the movable sleeve 8 is used to make the slot 10 on the top of the movable sleeve 8 engage with the slot 11 by moving the movable sleeve 8, thereby enabling the movable sleeve 8 to position the slot 11, thus preventing the welding gun body 2 from moving and falling off the moving end of the welding robot 1.

[0028] refer to Figure 3 A reset spring 12 is movably installed inside the movable groove 6. One end of the reset spring 12 is fixedly connected to the bottom of the inner wall of the movable groove 6, and the other end of the reset spring 12 is fixedly connected to the bottom of the movable sleeve 8.

[0029] As a technical optimization of this utility model, the reset spring 12 is set inside the movable groove 6, and the thrust generated by the reset spring 12 pushes the movable sleeve 8 upward, thereby facilitating the engagement of the movable sleeve 8 with the snap-fit ​​mechanism.

[0030] refer to Figure 2 A protective pad 13 is fixedly installed on the inner wall of the clamp 53. Several sets of protective pads 13 are arranged at equal intervals. The inner wall of the protective pad 13 is in contact with the left and right sides of the surface of the welding gun body 2.

[0031] As a technical optimization of this utility model, the protective pads 13 set inside the clamping plate 53 are used to protect the welding gun body 2 when the clamping plate 53 is clamping it, thereby preventing damage to the welding gun body 2.

[0032] The working principle and usage process of this utility model are as follows: During use, rotating the welding gun body 2 connects it to the moving end of the welding robot 1 via the connecting rod 4. Then, the push force generated by the return spring 12 pushes the moving sleeve 8 upward. The movement of the moving sleeve 8 causes the slot 10 at the top of the moving sleeve 8 to engage with the locking block 11, thereby positioning the moving sleeve 8 against the locking block 11 and preventing the welding gun body 2 from moving and falling off from the moving end of the welding robot 1. Rotating the adjustment knob 51 causes the bidirectional screw 52 to rotate, which in turn moves the clamping plate 53. The clamping plate 53 clamps the welding gun body 2. When the clamping plate 53 moves, the limiting rod 54 limits its movement. Multiple sets of protective pads 13 protect the clamping plate 53 from damage during clamping.

[0033] In summary, this welding robot torch changing device, through the setting of an adjustment knob 51, a movable groove 6, and a locking groove 10, rotates the adjustment knob 51, causing the bidirectional screw 52 to rotate, which in turn moves the clamping plate 53. The clamping plate 53 clamps the welding torch body 2. During the movement of the clamping plate 53, the movement is limited by the limiting rod 54. The movable sleeve is installed through the movable groove 6, and the moving groove 7 is opened through the welding torch body 2, allowing the moving rod 9 to move. The installation involves pushing the moving rod 9, which in turn moves the moving sleeve 8 within the moving groove 7 for adjustment. The movement of the moving sleeve 8 causes the slot 10 at its top to engage with the locking block 11, thus positioning the moving sleeve 8 around the locking block 11. This prevents the welding torch body 2 from moving away from the moving end of the welding robot 1 and potentially detaching. It also solves the problem that after prolonged use, the welding torch may experience wear, blockage, or damage. Furthermore, if the replacement process is cumbersome or time-consuming, it directly impacts the continuity and efficiency of the production line.
