Description

Technical Field

[0001] This utility model relates to the field of shock absorber sealing technology, and in particular to a shock absorber sealing resistance testing machine. Background Technology

[0002] Shock absorber seals play a crucial role in the performance and lifespan of shock absorbers, especially in complex operating environments, where their resistance directly affects the stability and reliability of the shock absorber. To ensure the quality and performance of shock absorbers, seal resistance testing is an essential step. Modern testing equipment employs intelligent and automated technologies to comprehensively evaluate various seal performance aspects, improving testing efficiency and accuracy, reducing human error, and enabling automatic defect identification and report generation. With the development of sensor technology, machine vision, and artificial intelligence, shock absorber seal resistance testing will become more efficient and precise, providing stronger support for the safe operation and performance assurance of mechanical equipment.

[0003] A search revealed an existing patent (publication number: CN220490367U) disclosing a shock absorber seal resistance testing machine. This machine includes a support frame, with a bottom frame installed on the inner side of the support frame. A frame groove is formed on the inner side of the bottom frame, and rotating shafts are installed at both ends of the frame groove. A rotating seat is installed on the end of each rotating shaft, and a rubber pad is placed at the bottom of the rotating seat. This invention allows the rotating seat to switch positions between below the pressure block and outside the support frame by rotating the shafts. When the rotating seat rotates and moves out from the inner area of ​​the support frame, the shock absorber seal is placed on the upper part of the rotating seat. Then, the rotating seat is rotated to directly below the pressure block. At this time, the pressure block moves downward under the drive of a cylinder, performing impact resistance testing on the shock absorber seal. The rotating seat can be rotated during loading and unloading to change its position, preventing accidental injury to operators from a malfunctioning cylinder accidentally driving the pressure block during manual handling of the test piece.

[0004] However, in actual use of the above solution, manual handling is still required during loading and unloading. Manual handling is slow, especially during mass production, which can extend the production cycle. Furthermore, operator fatigue or inattention can lead to improper handling, affecting equipment operation and the accuracy of test results. In addition, frequent manual handling increases safety risks, potentially causing operator injury or equipment damage, and also requires additional manpower, increasing production costs. The variability of manual operation can also affect the consistency of the testing process, reducing overall production efficiency.

[0005] Therefore, this utility model provides a shock absorber seal resistance testing machine. Utility Model Content

[0034] The first support frame 11 is symmetrically fixed to the top outer side of the base plate 1, and the two first support frames 11 are a group, and the two groups are symmetrically arranged. The base plate 1 supports and fixes the two groups of symmetrically arranged first support frames 11.

[0035] The conveying components are symmetrically arranged inside the two sets of first support frames 11 and the conveying directions are opposite.

[0042] The conveying assembly includes a conveyor belt 12 fixed to the inner side of the top of the first support frame 11. The first support frame 11 fixes both sides of the conveyor belt 12, which is driven by an internally installed drive motor (the conveyor belt 12 is prior art, refer to the conveyor belt, and will not be described further). Symmetrically arranged limiting rods 13 are fixedly connected to the outer sides of both ends of the conveyor belt 12, supporting and fixing the limiting rods 13 on both sides. The limiting rods 13 are slidably connected to the seal 43, limiting the seal 43 so that when the seal 43 moves with the conveyor belt 12 at the top, it can only move inside the limiting rods 13. Before being conveyed to the top of the conveyor belt 12, the seal 43 is corrected by an external correction assembly so that the angle of the seal 43 is suitable for the limiting method of the placement end of the transfer assembly (refer to the infeed and discharge methods). Figure 1 (Distinguish them by the movement arrows marked on the middle conveyor belt 12).

[0043] The material gripping assembly includes a first sliding cylinder 21 fixed to the inner side of the top of the second support frame 2. The second support frame 2 supports and fixes the crossbar in the first sliding cylinder 21. The cylinder in the first sliding cylinder 21 moves on the crossbar in the first sliding cylinder 21. A first fixing plate 22 is fixedly connected to the outer wall of the moving end of the first sliding cylinder 21. The cylinder in the first sliding cylinder 21 supports and fixes the first fixing plate 22 and drives the first fixing plate 22 to move.

The output end of the second sliding cylinder 23 is fixed. A second fixed plate 25 is fixedly connected to the second fixed plate 25. The output end of the second slider cylinder 23 supports and fixes the second fixed plate 25. The second fixed plate 25 is slidably connected to the slide rail 24 fixedly connected to the outer wall of the second slider cylinder 23. The slide rail 24 is fixed by the second slider cylinder 23, and the slide rail 24 limits the second fixed plate 25, so that the second fixed plate 25 can move up and down along the slide rail 24. A pneumatic claw 26 is fixedly connected to the outer wall of the second fixed plate 25. The pneumatic claw 26 is fixed by the second fixed plate 25, and the pneumatic claw 26 grips the sealing element 43 to realize automatic loading and unloading (the pneumatic claw 26 is existing technology, refer to the pneumatic clamp, and will not be described).

[0044] The detection assembly includes a hydraulic rod 31 fixedly connected to the top of the third support frame 3. The hydraulic rod 31 is supported and fixed by the third support frame 3. A connecting plate 32 is fixedly connected to the output end of the hydraulic rod 31, supporting and fixing the connecting plate 32. The hydraulic rod 31 also drives the connecting plate 32 to rise and fall. A sliding rod 34 is fixedly connected to the top wall of the connecting plate 32. The sliding rod 34 passes through the third support frame 3 and is slidably connected to the third support frame 3. The connecting plate 32 drives the sliding rod 34 to slide inside the base plate 1, thereby increasing the stability of the connecting plate 32 during the rising and falling process. A pressing head 33 is fixedly connected to the bottom of the connecting plate 32, supporting and fixing the pressing head 33. During the detection process, unqualified seals 43 are marked by an externally installed visual sensor and are removed separately after the detection is completed.

[0045] The transfer assembly includes a turntable 41 fixed to the output end of a motor 4. The motor 4 supports and fixes the turntable 41, and drives the turntable 41 to rotate. The top of the turntable 41 is fixedly connected with evenly distributed limiting grooves 42. The turntable 41 supports and fixes the limiting grooves 42. The limiting grooves 42 are engaged with the sealing element 43. The limiting grooves 42 have limiting slots for engaging the sealing element 43.

[0046] The inner wall of the limiting groove 42 is provided with a rubber layer. The rubber layer on the inner wall of the limiting groove 42 can protect the seal 43 and prevent the limiting groove 42 from damaging the outer wall of the seal 43 during the testing process.

[0047] Specifically, this shock absorber seal resistance testing machine operates as follows:

[0048] First, the seal 43 is conveyed onto the feed conveyor belt 12 by the external conveying assembly. During the conveying process, the angle of the seal 43 is corrected by the external correction device so that the seal 43 corresponds to the slot opened on the limiting groove 42.

[0049] When the conveyor belt 12 is transported to the end near the second support frame 2, the cylinder on the first slider cylinder 21 will move on the crossbar on the first slider cylinder 21, and at the same time drive the entire gripping assembly to move towards the side of the conveyor belt 12. During the process, the second slider cylinder 23 will use the second fixed plate 25 to drive the pneumatic claw 26 to align with the seal 43 on the conveyor belt 12. Then, the pneumatic claw 26 will grab the seal 43, and the first slider cylinder 21 will drive the entire gripping assembly along with the seal 43 to move away from the conveyor belt 12. The seal 43 grabbed by the pneumatic claw 26 will be aligned with the limiting groove 42 on the turntable 41. Then, the second slider cylinder 23 will drive the second fixed plate 25, the pneumatic claw 26 and the seal 43 to move downward, and put the seal 43 into the corresponding limiting groove 42.

[0050] Then, the motor 4 drives the turntable 41 to rotate, and the turntable 41 drives the top limiting groove 42 and the seal 43 to rotate, bringing the seal 43 to the bottom of the detection assembly. Then the motor 4 stops rotating, and the hydraulic rod 31 drives the connecting plate 32, the pressing head 33 and the sliding rod 34 to move to the bottom. The pressing head 33 presses the seal 43 to detect the resistance of the seal 43.

[0051] After the inspection is completed, the turntable 41 is driven by the motor 4 to continue rotating, and the inspected seal 43 is moved to the bottom of the material gripping component on the other side. The material gripping component picks up the inspected seal 43 in the limiting groove 42, and the first slider cylinder 21 and the second slider cylinder 23 cooperate to place the seal 43 on the discharge conveying component, and the conveying component transports the seal 43 out.
