When there is a difference in the gap size, the spacing between the bracket fixing hole 11 and the frame connecting hole cannot be guaranteed, and the installation of the gas cylinder assembly and the frame cannot be completed quickly and effectively. Summary of the invention

[0003] The purpose of the utility model is to provide a positioning device with simple structure and convenient operation, which is used for the subassembly of lightweight brackets and gas cylinders, solves the problem of assembly error between the gas cylinder assembly and the frame, and prevents the positioning device from damaging the paint on the bracket surface.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a positioning device for an automobile air cylinder and a bracket, comprising a crossbeam, a rubber pad, a groove-shaped positioning block, and a mounting hole. There are two groove-shaped positioning blocks, and the side wing surfaces of the two groove-shaped positioning blocks are fixedly connected by two symmetrically arranged crossbeams; a rubber pad is pasted on the inner groove surface of the groove-shaped positioning block; and two mounting holes are processed on the groove bottom surface of the groove-shaped positioning block.

[0005] Furthermore, the groove surfaces of the two groove-shaped positioning blocks are in the same direction, and the side wing surfaces are parallel to each other.

[0006] Furthermore, the groove-shaped positioning block and the crossbeam are fixedly connected by welding, and the upper surface of the groove-shaped positioning block is flush with the upper surface of the crossbeam.

[0007] Furthermore, the two mounting holes on the groove bottom surface of the groove-shaped positioning block are symmetrically evenly distributed through holes.

[0008] The beneficial effects of the utility model are as follows: compared with the prior art, the utility model provides a positioning device with a simple structure and easy operation, which is used for the subassembly of lightweight brackets and air cylinders, solves the problem of assembly error between the air cylinder assembly and the frame, and prevents the positioning device from damaging the paint on the surface of the bracket.

[0013] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0014] like Figures 1 to 3 As shown, a positioning device for an automobile gas cylinder and a bracket comprises a crossbeam 7, a rubber gasket 8, a groove-shaped positioning block 9, and a mounting hole 10. There are two groove-shaped positioning blocks 9, and the side wing surfaces of the two groove-shaped positioning blocks 9 are fixedly connected by two symmetrically arranged crossbeams 7; the inner groove surface of the groove-shaped positioning block 9 is pasted with a rubber gasket 8; and two mounting holes 10 are processed on the groove bottom surface of the groove-shaped positioning block 9;

[0015] The inner groove surface of the groove-shaped positioning block 9 is adhered with a rubber gasket 8, which can effectively prevent the positioning device 3 from damaging the paint on the surface of the bracket 1.

[0016] like Figure 2 As shown, in this embodiment, the groove surfaces of the two groove-shaped positioning blocks 9 are in the same direction, and the side wing surfaces are parallel to each other; this embodiment can effectively ensure the positioning accuracy of the positioning device.
