Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a mounting foot welding clamp. Background Art

[0002] The mounting foot is one of the main brackets for mounting a car seat. The mounting foot is welded by an outer mounting foot bracket and a reinforcing bracket. When welding the mounting foot bracket and the reinforcing bracket, a welding fixture is required to position and splice the mounting foot bracket and the reinforcing bracket. However, during the use of the existing welding fixture, in order to facilitate improving the positioning effect of the mounting foot, a variety of means are usually used to position the mounting foot in different ways. Although this can improve the clamping effect of the mounting foot, it is easy to spend too much time on fixing the mounting foot, which indirectly reduces the welding efficiency of the mounting foot.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Please refer to Figures 1 to 6 :

[0024] Embodiment 1: The utility model proposes a mounting foot welding fixture, comprising: a clamping cylinder 1, a driving cylinder 2 is fixedly installed at the center position inside the clamping cylinder 1; a clamping slide 3 is fixedly installed at the top end of the output end of the driving cylinder 2; a clamping shaft 4 is rotatably installed inside the clamping slide 3; a trigger member 5 is fixedly installed on the circumferential outer wall of the output end of the driving cylinder 2; a conversion slide 6 is opened on the circumferential inner wall of the clamping cylinder 1; the top end of the conversion slide 6 is a semi-spiral structure; a guide arc groove 7 with an arc structure is opened on the circumferential outer wall of the clamping slide 3.

[0025] When welding is required, first place the mounting foot bracket and reinforcement bracket to be welded on the positioning cylinder 11, so that the holes on the mounting foot bracket and the reinforcement bracket correspond to the positioning piece 15, and then start the driving cylinder 2, so that the driving cylinder 2 moves downward with the clamping slide 3, the clamping shaft 4, the fixed rod body 8, the clamping block 9 and the trigger member 5. When the trigger member 5 moves downward, the trigger member 5 will push the inclined surface of the trigger slider 18, so that the trigger slider 18 is forced to move to the left. During the movement, the trigger slider 18 will push the inclined surface of the force slider 17, so that the force slider 17 is forced to move upward with the driven slider 12 and the positioning piece 15, so that the positioning piece 15 rises and is inserted into the holes on the mounting bracket and the reinforcement bracket, and the basic positioning of the mounting foot bracket and the reinforcement bracket is performed.

[0026] Embodiment 2, on the basis of embodiment 1, a fixed rod body 8 is fixedly installed on the top of the clamping shaft 4; a clamping block body 9 is fixedly installed on the bottom outer end of the fixed rod body 8; a conversion slide column 10 is fixedly installed on the circumferential outer wall of the clamping shaft 4; the conversion slide column 10 is a cylindrical structure with a hemispherical outer end; the cylindrical part of the conversion slide column 10 is slidably installed inside the guide arc groove 7; the hemispherical part of the conversion slide column 10 is slidably installed inside the conversion slide groove 6; a positioning cylinder body 11 is fixedly installed on the left side of the clamping cylinder body 1; a driven slide column 12 is slidably installed inside the positioning cylinder body 11; a circular groove 13 with a circular structure is opened in the center of the top of the driven slide column 12; one end of a restoring spring 14 is embedded and installed inside the embedded groove 13.

[0027] When the driving cylinder 2 moves the clamping slide 3 downward, the clamping shaft 4 and the conversion slide 10 will rotate the fixed rod 8 under the action of the conversion slide 6, so that the fixed rod 8 rotates and moves the clamping block 9 to the upper position of the positioning cylinder 11, so that when the clamping slide 3 continues to descend, the clamping block 9 will descend to press and position the mounting foot bracket and the reinforcing bracket that have been basically positioned.

[0028] Embodiment 3, on the basis of embodiment 2, the other end of the restoring spring 14 is embedded and installed in the inner top end of the positioning cylinder 11; a positioning piece 15 is fixedly installed on the top of the driven slide 12; a mounting slot 16 is opened at the center position of the bottom of the driven slide 12; a force-bearing slider 17 is fixedly installed inside the mounting slot 16; the right end of the force-bearing slider 17 is an inclined structure; a trigger slider 18 is slidably installed at the connection position between the clamping cylinder 1 and the positioning cylinder 11; the top of the right end of the trigger slider 18 is an inclined structure; the top left side of the trigger slider 18 is in contact with the inclined surface of the force-bearing slider 17; the bottom end of the trigger member 5 is in contact with the inclined surface of the trigger slider 18.

[0029] After the driving cylinder 2 moves upward, the clamping slide 3 will also move upward with the clamping shaft 4, the fixed rod 8 and the clamping block 9. During the movement, the clamping shaft 4 will, under the action of the conversion slide 10 and the conversion slide 6, carry the fixed rod 8 and the clamping block 9 while rising and rotating, so that the clamping block 9 rotates to the side, to prevent the clamping block 9 from affecting the removal of the mounting foot bracket and the reinforcing bracket due to the corresponding position of the clamping block 9 and the positioning cylinder 11.

[0030] Working principle:

[0031] When in use, first place the mounting foot bracket and the reinforcing bracket to be welded on the positioning cylinder 11, so that the holes on the mounting foot bracket and the reinforcing bracket correspond to the positioning member 15, and then start the driving cylinder 2, so that the driving cylinder 2 moves downward with the clamping slide 3, the clamping shaft 4, the fixed rod 8, the clamping block 9 and the trigger member 5. When the trigger member 5 moves downward, the trigger member 5 pushes the inclined surface of the trigger slider 18, so that the trigger slider 18 is forced to move to the left. During the movement, the trigger slider 18 pushes the inclined surface of the force slider 17, so that the force slider 17 is forced to move upward with the driven slider 12 and the positioning member 15. Move, so that the positioning piece 15 rises and is inserted into the holes on the mounting bracket and the reinforcing bracket, and the mounting foot bracket and the reinforcing bracket are basically positioned. When the driving cylinder 2 moves the clamping slide 3 downward, the clamping shaft 4 and the conversion slide 10 will rotate the fixed rod body 8 under the action of the conversion slide 6, so that the fixed rod body 8 rotates the clamping block body 9 to the upper position of the positioning cylinder 11, so that when the clamping slide 3 continues to descend, the clamping block body 9 will descend to press and position the mounting foot bracket and the reinforcing bracket that have been basically positioned, and finally start to weld the spliced ​​and pressed mounting foot bracket and the reinforcing bracket.
