[0022] See also Figure 1-2 , the utility model provides a technical solution:

[0023] A force sensor welding fixing device includes a fixed base plate 1, a sliding inner cavity 2 is opened along both sides of the top center of the fixed base plate 1, a first screw rod 3 is set between the centers of both sides of the sliding inner cavity 2, a sliding rod 4 is slidably connected with the sliding inner cavity 2, a through hole 8 is opened at the centers of both sides of the sliding rod 4, the through hole 8 is located inside the first screw rod 3, a sliding plate 5 is set on the top of the sliding rod 4, an extension plate 6 is set on one side of the top of the sliding plate 5, a first V-shaped clamping plate 10 is set on the inner side of the extension plate 6, and a through hole is provided between the first V-shaped clamping plate 10 and the extension plate 6. The sliding plate 5 is connected to the first connecting block 9, and a sliding groove 12 is provided in the middle of the other side of the top of the sliding plate 5 in the horizontal direction. A second screw rod 13 is provided in the center of both sides of the sliding groove 12. A slider 14 is provided on the surface of the second screw rod 13. The slider 14 is fitted and slidably connected to the sliding groove 12. Circular holes are provided on the top of both sides of the slider 14, and a fixing screw 15 is inserted into the circular hole. The outer end of the fixing screw 15 is located on the outer side of the slider 14, and the inner end of the fixing screw 15 is provided with a second connecting block 16. The other end of the second connecting block 16 is provided with a second V-shaped clamping plate 20.

[0024] Furthermore, a first knob 7 is fixedly connected to the center of one side of the fixed base plate 1 , and an output end of the first knob 7 is connected to one end of the first screw rod 3 .

[0025] Furthermore, a second knob 19 is fixedly connected to the center of one side of the sliding plate 5 , and an output end of the second knob 19 is connected to one end of the second screw rod 13 .

[0026] Furthermore, a nut 17 is sleeved on the outer end surface of the fixing screw 15 , and the inner side surface of the nut 17 contacts the outer side surface of the slider 14 .

[0027] Furthermore, a rubber clamp 11 is provided on the outer side of the first V-shaped clamp 10. When the clamp at the slider 14 moves toward this point, the rubber clamp 11 will be appropriately compressed, and a number of anti-slip strips are provided on the inner side of the rubber clamp 11 to make the clamping and fixation of the force sensor more stable.

[0028] Example 2: Please refer to Figure 1 、 Figure 3 The difference between the second embodiment and the first embodiment is that the shape of the splint connected to the inner side of the fixing screw 15 is different. The shape of the splint in the first embodiment is the second V-shaped splint 20. The cross section of the splint in the second embodiment is rectangular. Figure 3 The fixing clamp 18 is selected according to the shape of the force sensor.

[0029] Working principle: It should be noted that the bottom of the fixed base plate 1 is fixedly mounted on the welding table of the welding device. When fixing the force sensor, first, a suitable clamping plate shape is selected according to the shape of the force sensor. For example, when the force sensor is circular, the clamping plate shape is selected as the second V-shaped clamping plate 20. When the shape of the force sensor is rectangular, the clamping plate shape is selected as the fixed clamping plate 18.

[0030] After selecting the splint, place one end of the force sensor to the side of the first V-shaped splint 10, and then the staff rotates the second knob 19. The rotation of the second knob 19 will rotate the second screw rod 13, and the rotation of the second screw rod 13 will move the slider 14 toward the first V-shaped splint 10. After the splint contacts the other side of the force sensor, the force sensor is fixed.

[0031] After the force sensor is fixed, the welding device will be started to weld it. During the welding process, it is sometimes necessary to adjust the position of the force sensor, which can be achieved by rotating the first knob 7. When the first knob 7 is rotated, the first screw rod 3 will rotate, and the rotation of the first screw rod 3 will move the sliding rod 4, thereby changing the position of the force sensor, thereby facilitating welding.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
