[0028] Embodiment one: a pressure detection mechanism for automobile shock absorber machining, like Figures 1-4As shown, including detection base 1, detection base 1 is provided with pressure assembly, clamping assembly 3, shock absorber body 4, pressure monitoring sensor 5;

[0029] The pressure assembly includes a wedge-shaped slider 22 mounted on the detection base 1, one side of the wedge-shaped slider 22 is connected with the output end of the telescopic cylinder 23, a rolling wheel 24 is arranged on the inclined surface of the wedge-shaped slider 22, a spring 27 connected with the positioning plate 28 is arranged on the upper end surface of the rolling wheel 24, and a jacking column 25 is further arranged on the upper end surface of the rolling wheel 24, the jacking column 25 penetrates through the positioning plate 28 and is connected with the push plate 29, and the pressure monitoring sensor 5 is mounted between the positioning plate 28 and the push plate 29;

[0030] The clamping assembly 3 includes a vertical adjusting frame 31 mounted on the push plate 29, and the vertical adjusting frame 31 is provided with an annular filler block 32 on one side.

[0031] In use, the annular filler block 32 at the upper and lower ends is aligned with the annular cavity at the upper and lower ends of the shock absorber body 4, and the annular filler block 32 is completely embedded in the annular cavity, so that the positioning shock absorber body 4 is stable, and then the telescopic cylinder 23 is started, the output end of the telescopic cylinder 23 is elongated, the inclined surface of the wedge-shaped slider 22 pushes the rolling wheel 24, the rolling wheel 24 rolls on the inclined surface while moving upward, the jacking column 25 on the upper end surface of the rolling wheel 24 moves upward, the jacking column 25 penetrates through the positioning plate 28 and drives the push plate 29 to move upward, the push plate 29 applies upward pressure to the shock absorber body 4 clamped above, and the annular filler block 32 on the push plate 29 contacts the shock absorber body 4 and applies pressure thereto, wherein the annular filler block 32 is made of a non-deformable material structure, and this pressure is indirectly transmitted to the push plate 29 through the vertical adjusting frame 31, and the push plate 29 is further transmitted to the pressure monitoring sensor 5, so that the pressure change can be monitored in real time. Compared with the traditional method of applying and detecting pressure on the shock absorber by using multiple connecting rods and complex hydraulic systems, the telescopic cylinder 23 pushes the wedge-shaped slider 22 in the present application, the rolling wheel 24 on the wedge-shaped slider 22 cooperates with the jacking column 25, and the jacking column 25 cooperates with the push plate 29 and the spring 27, which eliminates the traditional complex multiple connecting rods and hydraulic systems, greatly reduces the number of parts, not only reduces the manufacturing cost of the equipment, but also makes the assembly and maintenance more simple and convenient, and reduces the maintenance cost.

[0032] As Figures 1-4As shown, the pressing assembly further comprises a guide groove 2 mounted on the detection base 1, and a sliding seat 21 is arranged on the guide groove 2, and the wedge-shaped sliding block 22 is connected with the sliding seat 21. The cooperation of the guide groove 2 and the sliding seat 21 can provide accurate guidance for the movement of the wedge-shaped sliding block 22, and ensure that the wedge-shaped sliding block 22 can only move linearly in the direction specified by the guide groove 2, without left-right deviation or shaking, thereby ensuring the stability and accuracy of the entire pressing process.

[0033] As shown in Figures 1-4 The output end of the telescopic air cylinder 23 is provided with a connecting block 231, and the telescopic air cylinder 23 is stably connected with the wedge-shaped sliding block 22, and the connecting block 231 can stably transmit the thrust generated by the telescopic air cylinder 23 to the wedge-shaped sliding block 22, and also facilitates the subsequent disassembly and replacement of the wedge-shaped sliding block 22.

[0034] As shown in Figures 1-4 A top plate 11 is arranged above the detection base 1 and is stably connected with the detection base 1 through two support columns. Two extension plates 12 are horizontally and oppositely arranged on the two support columns. Guide columns arranged below the two extension plates 12 penetrate the positioning plate 28 and the pressing plate 29 in sequence. The top plate 11 is connected with the detection base 1 through the two support columns to form a stable frame structure, which provides a solid support foundation for the entire pressure detection mechanism, and ensures that the entire device will not deform or shake as a whole when the shock absorber body 4 is subjected to pressure detection, thereby ensuring the stability and accuracy of the detection process.

[0035] As shown in Figures 1-4 A through hole is formed in the middle position of the positioning plate 28, and a vertical guide cylinder 26 is arranged in the through hole. The upper end surface of the rolling wheel 24 extends out a jacking column 25, and the jacking column 25 penetrates the vertical guide cylinder 26. Meanwhile, the spring 27 extending from the upper end surface of the rolling wheel 24 is connected with the vertical guide cylinder 26. The vertical guide cylinder 26 can provide a vertical direction guiding action for the jacking column 25, so as to ensure that the jacking column 25 always maintains a vertical state during movement and can only move up and down along the axis direction of the vertical guide cylinder 26, thereby avoiding uneven distribution of pressure caused by the inclination of the jacking column 25 and affecting the accuracy of the detection result.

[0036] Embodiment two: a pressure detection mechanism for processing automobile shock absorbers, as shown in Figures 1-4 Two groups of vertical adjusting frames 31 are oppositely installed in the rectangular groove of the pressing plate 29 through the forward and reverse thread rod 33.

[0037] The annular filling block 32 arranged on one side of the vertical adjusting frame 31 is in a completely embedded and matched state with the annular cavity at the upper and lower ends of the shock absorber body 4.

[0038] In use, the positive and negative toothed rod 33 is rotated, and the two sets of vertical adjusting frames 31 move in opposite directions in the rectangular slot of the pressing plate 29. During the rotation of the positive and negative toothed rod 33, the approach of the ring-shaped filling block 32 to the ring cavities at the upper and lower ends of the shock absorber body 4 is closely observed. When the ring-shaped filling block 32 gradually approaches the ring cavities, it is ensured that the ring-shaped filling block 32 is accurately embedded until the ring-shaped filling block 32 and the ring cavities at the upper and lower ends of the shock absorber body 4 are in a completely embedded and fitted state. At this time, the shock absorber body 4 is firmly fixed between the two sets of vertical adjusting frames 31. Compared with the conventional bolt fixing method, the clamping time of the shock absorber body 4 on the detection equipment can be greatly shortened, the overall detection efficiency is improved, and batch detection operations are facilitated.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, and all of the above should be covered within the protection scope of the present application.
