[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0030] like Figure 1 As shown, an automatic welding fixture for a cab support includes:

[0031] The base plate 10 has a side limiting structure 11 at its front side.

[0032] A first clamping device that can simply clamp the bracket includes two sets of first clamping plates 14, each set of first clamping plates 14 having two plates, and the two sets of first clamping plates 14 are respectively located on the left and right sides of the top wall of the base plate 10.

[0034] It is worth noting that the base plate 10 and the side limiting structure 11 have been disclosed in an automatic welding fixture for a cab bracket (201921701983.6), and will not be described again here.

[0035] In practical use, the first clamping device can simply clamp the bracket to provide initial fixation, while the second clamping device can tightly clamp the bracket to limit its position and facilitate welding by the workers.

[0036] In summary, by setting up a first clamping device and a second clamping device, the bracket can be initially clamped by the first clamping device and the bracket can be limited by the second clamping device. Compared with the prior art, this can effectively prevent the bracket from tilting, and it is convenient to use and has a simple structure.

[0037] like Figure 2 , Figure 3 and Figure 4 As shown, a fixing plate 13 is fixedly installed on the right side of the top wall of the base plate 10, a movable plate 12 is provided on the left side of the top wall of the base plate 10, a first fixing plate 19 is fixedly installed on the left side of the top wall of the base plate 10, a second fixing plate 21 is fixedly installed on the left side of the movable plate 12, and a second bolt 20 is also provided on the top wall of the base plate 10. The second bolt 20 passes through the first fixing plate 19 and is threadedly connected to the first fixing plate 19. The right end of the second bolt 20 is rotatably connected to the left side of the second fixing plate 21.

[0038] A first through hole 17 is provided on the left and right side walls of the movable plate 12 and the fixed plate 13. A second through hole 18 is provided on the left and right side walls of the movable plate 12 and the fixed plate 13 at the front and rear ends of the first through hole 17. A first bolt 16 is provided on the top wall of the movable plate 12 and the fixed plate 13. The two first bolts 16 pass through the movable plate 12 and the fixed plate 13 respectively and extend into the cavity of the first through hole 17.

[0039] Two lifting blocks 25 are provided in the cavities of the two first through holes 17. The first bolt 16 also passes through the corresponding lifting block 25 and is threadedly connected to the lifting block 25. Multiple first clamping plates 14 are respectively fixedly installed on the side wall of the two sets of lifting blocks 25 on the left and right sides. A first rubber pad 26 is fixedly installed on the side wall of the two sets of first clamping plates 14 on the upper and lower sides.

[0040] A side plate 22 is fixedly installed on the side wall of each of the two sets of lifting blocks 25 on the left and right sides, which are far apart from each other. A fourth bolt 24 is provided on the side wall of each of the two sets of side plates 22. A third through hole 23 is opened on the top wall of the side plate 22. The fourth bolt 24 passes through the side plate 22 and extends into the cavity of the third through hole 23. The fourth bolt 24 and the side plate 22 are rotatably connected at the through point.

[0041] In practical use, when the operator rotates the second bolt 20, it can move left and right through the threaded connection with the first fixing plate 19. The movement of the second bolt 20 can drive the second fixing plate 21 to move, and the movement of the second fixing plate 21 can drive the moving plate 12 to move. The moving plate 12 cannot rotate because its bottom wall is attached to the top of the base plate 10. The two clamped brackets are brought closer to each other by moving the moving plate 12 closer to the fixing plate 13. When the threads at the upper and lower ends of the first bolt 16 are in opposite states, rotating the first bolt 16 can drive the two corresponding lifting blocks 25 to move closer or further apart. The movement of the lifting blocks 25 can drive the first clamping plate 14 to move, and the movement of the first clamping plate 14 can drive the first rubber pad 26 to move. The first rubber pad 26 clamps the bracket between the two first rubber pads 26. Due to the characteristics of the first rubber pad 26, the bracket will not be deformed by clamping. The first through hole 17 can limit the movement of the lifting block 25.

[0042] In summary, by setting up a first rubber pad 26, a first clamping plate 14, a lifting block 25, a first fixing plate 19, a second bolt 20, a first through hole 17, a first bolt 16, a moving plate 12, and a fixing plate 13, the moving plate 12 can be moved by rotating the second bolt 20, thereby bringing the two clamped brackets closer to each other. The first rubber pads 26 clamp the brackets by rotating the first bolt 16. Due to the characteristics of the first rubber pads 26, the brackets will not be deformed. It is convenient to use and has a simple structure.

[0043] like Figure 4 and Figure 5 As shown, a connecting rod 32 is fixedly installed between each of the two corresponding second clamping plates 15. A bottom block 28 is fixedly installed on the bottom wall of the connecting rod 32. The bottom wall of the bottom block 28 is hollow. A movable block 30 is movably installed inside the cavity of the bottom block 28. A spring 29 is fixedly installed on the top wall of the movable block 30. The spring 29 is fixedly connected to the cavity of the bottom block 28. A third fixing plate 31 is fixedly installed on the bottom wall of the movable block 30.

[0044] Each of the corresponding movable blocks 30 is located in the corresponding third through hole 23 cavity. Multiple fourth bolts 24 pass through the corresponding movable blocks 30 and are threadedly connected to the movable blocks 30. A third fixing plate 31 is fixedly installed on the bottom wall of the movable block 30. The third fixing plate 31 is attached to the bottom wall of the side plate 22. A second rubber pad 27 is fixedly installed on the bottom wall of the two sets of second clamping plates 15 on the left and right sides that are close to each other.

[0045] In practical use, rotating the fourth bolt 24 can move the corresponding moving block 30. The moving block 30 cannot rotate due to the limitation of the third through hole 23 and the third fixing plate 31, thus clamping the bracket at different positions. The movement of the moving block 30 can move the bottom block 28, which in turn can move the second clamping plate 15. The movement of the second clamping plate 15 can then move the second rubber pad 27. The force of the two springs 29 pulls the upper and lower sets of second rubber pads 27 closer to each other, thus clamping the bracket. Through multiple points on the left and right sides, the bracket can be effectively prevented from tilting. The connecting rod 32 can connect the two corresponding second clamping plates 15.

[0046] In summary, by setting up the second rubber pad 27, lifting block 25, connecting rod 32, base block 28, spring 29, third fixing plate 31, moving block 30, fourth bolt 24, third through hole 23 and side plate 22, the bracket can be clamped at different positions by moving the multiple second rubber pads 27 left and right. Through multi-point clamping, it can effectively prevent it from tilting. The material of the multiple second rubber pads 27 can also effectively prevent the bracket from slipping.
