Description

Technical Field

[0001] The utility model belongs to the technical field of air bag shock absorber processing, in particular to an automatic air pressure nozzle device. Background Art

[0002] The airbag shock absorber is a shock absorbing structure on the car. It adopts the principle of pneumatic shock absorption. When the vehicle encounters a bumpy situation during driving, the airbag shock absorber can reduce the shock and buffer the impact, thereby improving the driving experience of the car. Such as heavy truck airbags, etc.

[0003] The main structure of the airbag shock absorber includes a plastic shell of the airbag end and an airbag sealed on the plastic shell of the airbag end. When in use, a certain pressure of gas is pumped into the airbag to form an airbag shock absorber with a pneumatic shock absorbing effect.

[0004] In the processing of the airbag shock absorber, specifically, in the processing of the airbag end plastic shell, the airbag end plastic shell blank is obtained by injection molding. The plastic shell blank contains an air nozzle connection port, and the air nozzle is installed on the air nozzle connection port by press-fitting or threaded connection.

[0005] Among them, the press-fitting method for installing the air nozzle is the most common method in the actual production process because of its convenient processing, high efficiency, and easy subsequent disassembly.

[0006] However, due to the small size of the air nozzle and the special-shaped shape of the plastic shell, during the press-fitting process of the air nozzle, the small air nozzle is difficult to install on the plastic shell and press-fit. Firstly, the special-shaped plastic shell is difficult to position, and secondly, the air nozzle is small in size. Therefore, press-fitting is more difficult, such as the air nozzle is difficult to align and feed onto the air nozzle interface.

[0007] Therefore, in actual working process, the air nozzle can only be processed by manual pressing. Obviously, this method is not only very inefficient, but also the plastic shell with special structure and the small air nozzle are difficult to connect together. Utility Model Content

[0063] The same method as the above-mentioned shell workpiece 4 loading method is as follows: first, the second clamping jaw cylinder 73 clamps the air nozzle 741 and loads it onto the air nozzle installation opening on the shell workpiece 4 .

[0067] Example 2

[0068] like Figure 1-10 As shown, this embodiment discloses the specific structure and working principle of the clamp 5 and the disc-shaped workbench 2 based on the structure of the embodiment 1.

[0069] A motor for driving the disc-shaped workbench 2 to rotate is installed on the top of the workbench 1. In the existing installation method, the output shaft of the motor is fixedly installed on the disc-shaped workbench 2. And in order to keep the disc-shaped workbench 2 able to rotate smoothly during the rotation process, the bottom edge of the above-mentioned disc-shaped workbench 2 is assembled and connected with a number of annularly distributed support wheel assemblies (the support wheel assembly includes a support rod 12 fixedly installed at the top position of the workbench 1, and a support roller 121 is installed on the top of the support rod 12, and the support roller 121 supports rolling on the bottom of the disc-shaped workbench 2); during the rotation of the disc-shaped workbench 2, the rotation is supported by the support wheel assembly, specifically, the support roller 121 supports rolling. During the rotation of the disc-shaped workbench 2, the stability of the rotation is maintained by the supporting rolling action of the support wheel assembly.

[0070] In order to realize the special-shaped shell workpiece 4, the above-mentioned disc-shaped tooling table 2 is equipped with a plurality of fixtures 5 (the fixture 5 is located at the top edge of the disc-shaped tooling table 2. During operation, the rotating disc-shaped tooling table 2 transports the shell workpiece 4 loaded by each fixture 5 to the designated station for processing.

[0071] The specific structure of the fixture 5 is:

[0072] The clamps 5 include a clamp base 51 fixedly mounted on the top of the disc-shaped workbench 2; a U-shaped clamp plate 52 is assembled and connected to the clamp base 51, and the shell workpiece 4 is limited in the U-shaped clamp plate 52 (specifically, located in the U-shaped cavity of the U-shaped clamp plate 52), and the U-shaped clamp plate 52 includes a supporting portion 521 supported at the bottom position of the shell workpiece 4, and the supporting portion 521 is integrally formed with an L-shaped limiting portion, and the upper end of the shell workpiece 4 is limited at the upper end of the L-shaped limiting portion.

[0073] Specifically, an arc-shaped bayonet is provided on the inner side wall of the upper end of the L-shaped limiting portion; the upper end of the shell workpiece 4 is limited in the arc-shaped bayonet, and the arc-shaped bayonet is adapted to the shape of the shell workpiece 4 to limit the upper end of the shell workpiece 4.

[0074] To further enhance the locking and positioning effect of the shell workpiece 4 , the top of the support portion 521 is fixedly connected to a limiting structure 53 for limiting the shell workpiece 4 . When the shell workpiece 4 is loaded onto the support portion 521 , the limiting structure 53 is limited in the shell workpiece 4 .

[0075] Specifically, the limiting structure 53 includes an outer limiting seat 531 fixedly connected to the top position of the support portion 521, and the outer limiting seat 531 is in the shape of a columnar structure (the bottom of the shell workpiece 4 is supported on the top of the outer limiting seat 531), and a limiting protrusion 532 is fixedly connected inside the outer limiting seat 531, and the limiting protrusion 532 is limited inside the shell workpiece 4.

[0076] At the same time, in order to avoid instability of the shell during processing, a limiting groove structure 5231 is provided on the outer wall of the limiting convex seat 532. When the shell workpiece 4 is inserted into the limiting convex seat 532, the limiting groove structure 5231 and the convex strip structure in the shell workpiece 4 (the convex strip structure is a convex strip structure provided in the shell workpiece 4, which is actually a reinforcing rib in the shell workpiece 4) are plugged into each other for limiting.

[0077] In order to increase the rotation stability of the disc-shaped workbench 2 and avoid the hidden danger of installation accidents caused by the centrifugal flying of the disc-shaped workbench 2 due to the reduction of the rotation stability of the disc-shaped workbench 2 (such as the loose connection position of the rotating shaft), the top of the above-mentioned workbench 1 is fixedly connected with an arc-shaped abutment plate 3 arranged on the outer wall of the disc-shaped workbench 2, and the arc-shaped abutment plate 3 is provided with an arc-shaped opening adapted to the disc-shaped workbench 2 (the arc-shaped opening and the disc profile of the disc-shaped workbench 2 maintain a small distance. Once the disc-shaped workbench 2 moves unsteadily, the outer wall of the disc-shaped workbench 2 will abut against the arc-shaped opening, which can not only realize the correction of the rotation movement of the disc-shaped workbench 2, but also realize the limit protection to prevent the disc-shaped workbench 2 from deviating too much from the movement trajectory); the two ends of the arc-shaped abutment plate 3 are respectively fixedly connected with brackets fixedly installed on the workbench 1.

[0078] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
