Description

Technical Field

[0001] This invention relates to the technical field of shock absorber testing, and in particular to a pressure testing device for shock absorber processing. Background Technology

[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of springs after absorbing shocks and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride comfort of the vehicle. When driving over uneven roads, although the shock-absorbing springs can filter out road vibrations, the springs themselves will still have reciprocating motion. Shock absorbers are used to suppress this spring jumping. After the shock absorbers are manufactured, pressure testing devices are used to test the manufactured shock absorbers in order to ensure the quality of the shock absorption.

[0003] In the prior art, pressure testing devices use a main structure consisting of a housing and a door. Inside the housing, a testing mechanism consisting of a pressure plate and a test seat is installed to perform pressure tests on shock absorbers. This device has a simple structure and is easy to use. By performing pressure tests on automotive shock absorbers in a closed environment, it has high safety and avoids accidents caused by the flying of parts due to the breakage of defective automotive shock absorbers.

[0004] However, in the actual testing process, it is necessary to open the chamber door, place the shock absorber to be tested into the test seat, and then close the chamber door for testing. After testing, it is necessary to reopen the chamber door and take out the tested shock absorber from the test seat. This is time-consuming and labor-intensive when testing a large number of shock absorbers. Furthermore, the testing work needs to be stopped during the feeding and unloading process, which means that the efficiency of the shock absorber testing work needs to be improved. Therefore, there are areas for improvement. Summary of the Invention

[0029] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0030] Reference Figures 1-7 This invention discloses a pressure detection device for processing shock absorbers, including a workbench 1 and a support leg 2. The workbench 1 is supported by the support leg 2. A material collection structure is set on the left support leg 2. A detection structure is set in the middle of the workbench 1. A rotating disk 3 is set on the left side of the workbench 1 through a rotation switching structure. Multiple mounting plates 5 are fastened to the rotating disk 3 by bolts. Each mounting plate 5 is provided with a placement structure.

[0031] The rotary switching structure includes a motor 8 installed under the workbench 1. The output shaft of the motor 8 passes through the top of the workbench 1 and connects to the rotating column 10. An installation sleeve 11 is fixedly sleeved on the rotating column 10. Multiple connecting plates 9 are connected to the side of the installation sleeve 11. One end of the connecting plate 9 is connected to the rotating disk 3.

[0032] The placement structure includes a placement seat 6 set above the mounting plate 5. The placement seat 6 is set on the mounting plate 5 by a flipping structure. A placement groove 7 is opened in the middle of the upper part of the placement seat 6. A shielding structure is set at the top of the placement seat 6.

[0033] The detection structure includes two vertical plates 4 bolted to the middle of the front and rear sides of the workbench 1. Multiple fixing rods 45 are connected between the tops of the two vertical plates 4. Fixing seats 12 are fixedly mounted on the fixing rods 45, and hydraulic cylinders 13 are mounted on the fixing seats 12. A lifting plate 14 is connected to the bottom of the output shaft of the hydraulic cylinder 13. First connecting rods 15 are connected to the four corners of the lifting plate 14. Pressure plates 16 are mounted at the bottom of the first connecting rods 15, and pressure sensors 17 are fixedly mounted in the middle of the pressure plates 16. The starting motor 8 drives the rotating column 10 and the mounting sleeve 11 to rotate, which in turn drives the rotating disk 3 via the connecting plate 9. The workbench 1 drives the placement seat 6 to rotate. When the shock absorber in the corresponding placement seat 6 rotates to below the pressure plate 16, the hydraulic cylinder 13 on the fixed seat 12 is activated to drive the lifting plate 14 to move down, thereby driving the pressure plate 16 to move down and press against the shock absorber. This realizes the pressure detection of the shock absorber. The pressure sensor 17 detects the pressure on the shock absorber. At the same time, the shock absorber to be tested can be placed on other placement seats 6, and the tested shock absorber can be unloaded in the corresponding placement seat 6, so that the working time is fully utilized, thereby improving the efficiency of the testing work.

[0034] See Figures 5-7 The shielding structure includes four vertical rods 18 connected to the upper corners of the placement base 6. A shielding tube 19 is installed at the top of the vertical rods 18. A top tube 20 is installed at the top of the shielding tube 19. A straightening structure is installed on the top tube 20.

[0035] The straightening structure includes multiple through slots 24 opened on the jacking pipe 20. The multiple through slots 24 are distributed at equal angles around the circumference of the jacking pipe 20. A through plate 23 moves through each through slot 24. A straightening strip 22 is installed at one end of the through plate 23 inserted into the jacking pipe 20. The side of the straightening strip 22 away from the through plate 23 is arc-shaped. The upper and lower ends of the straightening strip 22 are inclined. The other end of the through plate 23 is connected to a driving plate 21. An adjustment structure is provided on the shielding pipe 19.

[0036] The adjustment structure includes an annular groove 25 on the side of the shielding tube 19. The groove wall of the annular groove 25 is threaded, and a threaded sleeve 26 is fitted into the annular groove 25. The threaded sleeve 26 has anti-slip textures. A top ring 27 is rotatably mounted on the top of the threaded sleeve 26, and a rotating ring 28 is rotatably mounted on the top ring 27. Multiple second connecting rods 29 are connected to the rotating ring 28. A drive ring 30 is installed at the top of the second connecting rods 29. A drive groove 31 is provided on the drive plate 21 for the drive ring 30 to pass through. After the shock absorber is inserted into the placement groove 7 of the placement seat 6, the shielding tube 19 is used to adjust the shock absorber during the testing process. It serves as a shield and, according to the actual size of the shock absorber, the screw sleeve 26 can be rotated in the annular groove 25 to move the top ring 27. The rotating ring 28 drives the top of the second connecting rod 29 to drive the ring 30 to slide in the driving groove 31 of the driving plate 21. The compression of the driving groove 31 wall by the driving ring 30 drives multiple straightening strips 22 to move towards each other on the top pipe 20. The straightening strips 22 adhere to the shock absorber, which straightens the shock absorber and ensures that the shock absorber is in a vertical state during testing, thereby ensuring the quality of the testing work.

[0037] See Figure 1 , Figure 2 , Figure 5 and Figure 6 The flipping structure includes a U-shaped seat 32 mounted on the mounting plate 5. The top of the U-shaped seat 32 rotates through the rotating shaft 33. Both ends of the rotating shaft 33 are fixedly fitted with flipping plates 34. The top of the flipping plates 34 are connected to the placement seat 6. A gear 35 is fixedly fitted in the middle of the rotating shaft 33. A driving structure is provided between the rotating shaft 33 and the worktable 1.

[0038] The driving structure includes a groove in the middle of the inner wall of the U-shaped seat 32, a slide plate 36 is slidably arranged in the groove, the end face of the slide plate 36 is inverted "T" shape, a driving bar 37 is arranged on the slide plate 36, the gear 35 is meshed with the teeth on the driving bar 37, a protrusion 38 is arranged at one end of the slide plate 36, and a rod 39 is fixedly inserted through the protrusion 38. A first arc groove 40 is opened on the inner side of the rotating disk 3 on the worktable 1, and a second arc groove 41 is opened on the worktable 1 to connect the two ends of the first arc groove 40. The bottom end of the rod 39 is movably inserted into the first arc groove 40.

[0039] The material collection structure includes a material inlet 42 located in the middle of the left side of the workbench 1, a collection frame 44 on the left support leg 2, a material plate 43 connected to the bottom of the workbench 1 near the material inlet 42, the material plate 43 being inclined and extending into the collection frame 44, a sponge pad on the inner wall of the collection frame 44, and the rotation disk 3 driving the tested shock absorber in the placement seat 6 to move towards the material position, thereby driving the bottom end of the insertion rod 39 to slide from the first arc groove 40 to the second arc groove 41, thereby pulling the corresponding slide plate 36 and the driving bar 37 to move towards the axis of the rotation disk 3, and driving the rotating shaft 33 to rotate through the gear 35, thereby driving the top of the flip plate 34 to rotate down the placement seat 6, and under the gravity of the shock absorber in the placement seat 6, the tested shock absorber is poured onto the material plate 43, and then discharged from the material plate 43 into the collection frame 44 for collection.

[0040] The implementation principle of a pressure detection device for shock absorber processing according to an embodiment of the present invention is as follows: The starting motor 8 drives the rotating column 10 and mounting sleeve 11 to rotate. The connecting plate 9 drives the rotating disk 3 to rotate on the worktable 1, causing the placement seat 6 to rotate. When the shock absorber in the corresponding placement seat 6 rotates to below the pressure plate 16, the hydraulic cylinder 13 on the fixed seat 12 is activated to move the lifting plate 14 downwards, thereby causing the pressure plate 16 to move downwards and press against the shock absorber. This achieves the pressure detection of the shock absorber. The pressure sensor 17 detects the pressure applied to the shock absorber. Simultaneously, shock absorbers to be tested can be placed on other placement seats 6. After inserting the shock absorber into the placement groove 7 of the placement seat 6, the shielding tube 19 acts as a shield during the testing process. Furthermore, according to the actual size of the shock absorber, the screw sleeve 26 can be rotated in the annular groove 25, causing the top ring 27 to move. The rotating ring 28 drives the top of the second connecting rod 29 to drive the ring 30 on the belt of the driving plate 21. The device slides in the moving groove 31, and the squeezing of the groove wall by the driving ring 30 drives multiple straightening bars 22 to move closer to each other on the top pipe 20. The straightening bars 22 adhere to the shock absorber, which straightens the shock absorber and ensures that the shock absorber is in a vertical state during testing, thus ensuring the quality of the testing work. After the shock absorber is tested, the rotating disk 3 drives the tested shock absorber in the placement seat 6 to move towards the unloading position. During this process, the bottom end of the insertion rod 39 slides from the first arc groove 40 to the second arc groove 41, thereby pulling the corresponding slide plate 36 and the driving bar 37 to move closer to the axis of the rotating disk 3. The gear 35 drives the rotating shaft 33 to rotate, thereby driving the top of the flip plate 34 and the placement seat 6 to rotate down. Under the gravity of the shock absorber in the placement seat 6, the tested shock absorber is poured onto the unloading plate 43 and then unloaded into the collection frame 44 for collection. This completes the testing of the shock absorber.

[0041] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
