Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts repair, in particular to a fastening tool for automobile parts repair. Background Art

[0002] With the rapid development of the automobile industry, the demand for automobile parts maintenance is also increasing. In the process of automobile maintenance, fastening tooling is an important tool used to fix and fasten automobile parts to ensure their stability and safety. In order to adapt to the clamping of automobile parts of different sizes and thus improve maintenance efficiency, existing tooling has gradually made technical improvements.

[0003] For example, the patent with publication number CN219056423U discloses an automobile parts fastening device, which can perform multiple fixations on the spare tire by means of a supporting device, a fastening device and a buffer device, thereby avoiding the phenomenon of unstable fixation of the spare tire and loosening of the spare tire, further improving the stability of the equipment in fastening the spare tire, improving the degree of protection for the spare tire, and at the same time improving the fastening efficiency of the spare tire.

[0004] Although the above-mentioned tooling can adapt to automobile tire parts of different sizes and has stable clamping, there are many automobile parts and many of them have large size differences. If the method of fixing individual parts on the tooling in sequence before repairing is adopted, the overall repair efficiency will be reduced, and the maintenance personnel's working time will be wasted in a large amount in clamping automobile parts. Therefore, the utility model provides a fastening tooling for automobile parts repair. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a fastening tool for automobile parts maintenance, which solves the problem that a large amount of working time of maintenance personnel is wasted on clamping automobile parts.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a fastening tool for automobile parts maintenance, including a bracket, a clamping mechanism capable of fastening a variety of automobile parts is arranged on the top of the bracket, and the clamping mechanism includes:

[0007] A plurality of telescopic components are arranged on the inner side of the top of the bracket, including a sleeve fixedly installed on the top of the bracket, and a telescopic rod is slidably installed on the inner wall of the sleeve, and the telescopic rod is a hollow structure;

[0009] The gas filling assembly is arranged on the top outer side of the bracket and is used to fill the closed cavity formed by the sleeve and the telescopic rod with gas;

[0010] The pressure relief component is arranged on the top of the inflatable component and is used to control the overall peak air pressure inside the inflatable component.

[0011] Preferably, the inflation assembly includes an inflation box fixedly mounted on the top of the bracket, the lower end of the inflation box is interconnected with a first air pipe, the bottom of the bracket is fixedly connected with a mounting base plate, the upper end of the mounting base plate is fixedly mounted with an inflation pump, and one end of the inflation pump is connected to a second air pipe.

[0012] Preferably, a manual air valve is installed between the first air pipe and the second air pipe.

[0013] Preferably, the pressure relief assembly includes a pressure relief cylinder fixedly installed on the top of the inflation box, the lower end of the pressure relief cylinder is slidably connected to a pressure column, the top of the pressure column is fixedly connected to a first spring gasket, the top inner wall of the pressure relief cylinder is fixed with a second spring gasket, a compression spring is welded between the first spring gasket and the second spring gasket, and a plurality of groups of air relief holes are provided on the outer side wall of the lower part of the pressure relief cylinder.

[0015] Preferably, the number of telescopic components is twice the number of clamping components.

[0016] Beneficial Effects

[0017] The utility model provides a fastening tool for automobile parts maintenance. Compared with the prior art, it has the following beneficial effects:

[0018] (1) The fastening tool for automobile parts maintenance is designed with multiple sets of telescopic components and clamping components, and the clamping is driven by air pressure. It can simultaneously clamp multiple sets of automobile parts of different sizes, eliminating the need for maintenance personnel to repeatedly fix multiple automobile parts, thereby improving maintenance efficiency. During the specific operation, the automobile parts to be processed are placed in the clamping components of the tool, and then the manual air valve is opened, and then the air pump is started. The air pump injects external gas into the closed inner cavity formed by the sleeve and the telescopic rod through the delivery pipeline formed by the first air pipe and the second air pipe. During the inflation process, the air pressure will continue to increase, and then the telescopic rod in the sleeve will be pushed to perform telescopic movement. The sliding ring on the U-shaped cross bar is moved by the thrust, and the second clamping rod is driven to move synchronously, cooperating with the first clamping rod to clamp and fix the automobile parts, thereby facilitating relevant personnel to perform maintenance.

[0019] (2) When the fastening tool for repairing automobile parts is inflated as a whole, the air pressure column is affected by the air pressure and contracts toward the inside of the pressure relief cylinder, thereby exerting a squeezing effect on the compression spring. When the air pressure exceeds a certain value, the pressure relief cylinder rises, and the gas inside the tool is discharged through the exposed air vent, thereby controlling the internal air pressure below the peak value, thereby ensuring that the clamping rod will not be over-extruded, thereby causing wear on the surface of the automobile part.

The air pressure will continue to increase during the inflation process, and then the telescopic rod 212 in the sleeve 211 will be pushed to perform telescopic movement.
