[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4 , the utility model provides a technical solution:

[0027] A pressure detection device for automobile shock absorber processing, comprising:

[0028] The main structure includes a box body 1 and a door 2, the door 2 is installed on the opening side of the box body 1, and a visual window is provided on the door 2;

[0029] It also includes a detection mechanism arranged inside the box body 1 for performing pressure detection on the automobile shock absorber; the detection mechanism includes a pressure plate 4 and a test seat 5, a hydraulic cylinder 3 is installed at the bottom of the box body 1, the lower end of the hydraulic rod of the hydraulic cylinder 3 passes through the top of the box body 1 and is fixedly connected to the top center of the pressure plate 4, the test seat 5 is located at the inner bottom center of the box body 1, and a positioning groove 6 is provided on the top of the test seat 5 for positioning the lower end of the automobile shock absorber.

[0030] The system also includes a fixing mechanism for securing the upper end of the vehicle shock absorber, comprising a fixing plate 8 and clamping blocks 11. The fixing plate 8 is located below the pressure plate 4, and the clamping blocks 11 are located on both sides of the bottom of the fixing plate 8. Two sets of side plates 9 are symmetrically arranged at the bottom of the fixing plate 8. Cylinders 10 are fixedly mounted on the side plates 9. The piston rod ends of the two sets of cylinders 10 pass through the side plates 9 and are respectively connected to the two sets of clamping blocks 11.

[0031] When in use, open the door 2, place the upper end of the shock absorber under the fixed plate 8, start the cylinder 10 so that the two sets of clamping blocks 11 clamp and fix the upper end of the shock absorber. After closing the door 2, start the hydraulic cylinder 3 to drive the pressure plate 4 and the fixed plate 8 to descend. After the lower end of the shock absorber is inserted into the positioning groove 6, it begins to bear the pressure of the hydraulic cylinder 3, thereby realizing the pressure detection of the shock absorber;

[0032] Among them, see Figure 2-4 :

[0033] The clamping groove of the clamping block 11 is arranged in a V shape, and a plurality of groups of rubber strips 12 are evenly distributed in the clamping groove of the clamping block 11 .

[0034] The test seat 5 is arranged in a conical shape with a small top and a large bottom. A rubber pad 7 is arranged at the bottom of the test seat 5. The positioning groove 6 is arranged in a conical shape with a large top and a small bottom.

[0035] Since the clamping block 11 is arranged in a V shape, when the clamping block 11 fixes the shock absorber, the shock absorber can remain in a vertical state, thereby preventing the shock absorber from tilting during testing. The rubber strip 12 provided in the clamping groove of the clamping block 11 can improve the firmness of the clamping block 11 in clamping the shock absorber.

[0036] The V-shaped clamping block 11 and the tapered positioning groove 6 enable the device to be adapted to shock absorbers of different diameters, thereby improving the practicality and applicability of the device.

[0037] At the same time, the conical test seat 5 can make the test seat 5 have good stability, and the test seat 5 is not easily offset due to force. The rubber pad 7 at the bottom of the test seat 5 can play a certain buffering role to prevent the test seat 5 from being damaged by excessive force on the box 1.

[0038] For further information, see Figure 3-4 :

[0039] A connecting rod 13 is symmetrically arranged on the top of the fixed plate 8, and the connecting rod 13 is slidably inserted into the pressure plate 4, and a limit block 14 is provided on the upper end of the connecting rod 13. The fixed plate 8 and the pressure plate 4 are coaxially arranged, and a pressure sensor 15 is installed at the top center of the fixed plate 8.

[0040] When the shock absorber is fixed by the clamp 11, the fixed plate 8 is suspended below the pressure plate 4 through the connecting rod 13, and the pressure sensor 15 does not apply force. As the hydraulic rod extends, the lower end of the shock absorber is inserted into the positioning groove 6, and the fixed plate 8 gradually approaches the pressure plate 4 until the two are in contact with each other. The pressure exerted by the hydraulic cylinder 3 on the shock absorber can be detected and recorded by the pressure sensor 15 between the fixed plate 8 and the pressure plate 4.

[0041] Among them, a control panel is installed on the box door 2, which includes a display screen and control buttons. The control panel is used to control the air cylinder 10 and the hydraulic cylinder 3. The pressure sensor 15 signal is connected to the control panel, and the detection value of the pressure sensor 15 is displayed and recorded on the display screen;

[0042] The control method of the control panel of this application is to use a PLC controller built into the control panel. The control circuit of the PLC controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, this application document is mainly used to protect mechanical devices, so this application document will no longer explain the control method and circuit connection in detail.

[0043] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
