Description

Technical Field

[0001] The present application relates to the field of automobile parts detection, and in particular to a shock absorber anti-vibration detection device. Background Art

[0002] Shock absorbers are also called shock absorbers. The shock absorber dynamometer fatigue tester is a professional equipment used to test shock absorbers. The equipment consists of a control system, a loading system, a measurement system, and a sample fixture, and is used to test the performance and durability of shock absorbers. During the test, the shock absorber dynamometer fatigue tester will perform various loading tests on the shock absorber according to the preset test procedures to evaluate its shock absorption effect and durability in the actual working process. This equipment is widely used in automobiles, motorcycles, engineering machinery and other fields. During the test of the shock absorber dynamometer fatigue tester currently used, the sliding parts of the loading system shake violently during high-speed reciprocating motion, which can easily cause errors in product testing. Summary of the invention

[0003] In order to reduce the shaking and trembling problems during the operation of a shock absorber dynamometer fatigue testing machine, the present application provides a shock absorber anti-seismic detection device.

[0004] The present application provides a shock absorber anti-seismic detection device that adopts the following technical solution: A seismic detection device for a shock absorber comprises a frame, a detection fixture, a loading mechanism and a sensor, wherein two detection fixtures are provided, and the two detection fixtures are respectively connected to the frame in a sliding manner, and the sliding directions between the two detection fixtures and the frame are consistent, and the sensor is used to collect performance parameters of the workpiece; the loading mechanism comprises a motor and two sliding brackets, and the two sliding brackets are respectively connected to the two detection fixtures in a one-to-one correspondence, and the sliding bracket comprises a frame, and the sliding bracket is connected to the detection fixture through the frame, and a sliding seat is provided on the inner side of the frame, and the sliding seat is connected to the frame in a sliding manner, and the sliding direction between the sliding seat and the frame is perpendicular to the sliding direction between the detection fixture and the frame; the sliding seat is provided with a crank, and a driving shaft is commonly connected between the two cranks, and the loading directions of the two cranks are opposite, and the driving shaft is rotationally connected to the frame, and a transmission assembly is connected between the output shaft of the motor and the driving shaft.

[0005] By adopting the above technical solution, when using the shock absorber anti-seismic detection device for anti-seismic detection, the two shock absorbers are respectively installed on two detection fixtures. The motor drives the drive shaft to rotate, and the drive shaft drives the two sliding seats to rotate at the same time through two cranks. The rotational motion of the sliding seat is decomposed into two vertical linear motions, thereby driving the detection fixture to repeatedly apply pressure to the shock absorber. The loading directions of the two cranks are opposite, which can make the two cranks form a mutual balance effect to a certain extent, which is beneficial to reduce the jitter of the loading mechanism, and when the energy released by one shock absorber can be used as energy to drive the loading of the other shock absorber, it is beneficial to improve the efficiency of energy utilization.

[0006] Optionally, the driving shaft is provided with a shaft mounting seat, the shaft mounting seat includes two shaft mounting parts, an intermediate connecting part is connected between the two shaft mounting parts, the intermediate connecting part is fixedly connected to the frame, and the transmission assembly is located between the two shaft mounting parts.

[0007] By adopting the above technical solution, the transmission position between the transmission assembly and the drive shaft is located between the two shaft mounting parts, so that the transmission part of the drive shaft is limited by the two shaft mounting parts, which is conducive to making the rotation of the drive shaft more stable and smooth.

[0008] Optionally, a rotating shaft is provided at one end of the crank away from the driving shaft, and the rotating shaft is rotatably connected to the sliding seat. A reinforcing arm is provided at one end of the rotating shaft away from the crank, and the center line of the reinforcing arm and the center line of the crank are located in the same plane. A positioning seat is provided at one end of the reinforcing arm away from the rotating shaft, and the positioning seat is fixedly connected to the frame.

[0009] By adopting the above technical solution, when the driving shaft drives the crank to rotate, the crank reinforcing arm rotates synchronously with the crank, and the crank and the reinforcing arm respectively support the two sides of the sliding seat, which can make the movement of the sliding seat more stable.

[0010] Optionally, the transmission assembly includes a driving gear and a driven gear, the driving gear is mounted on the output shaft of the motor, and the driven gear is rotatably mounted on the drive shaft.

[0011] By adopting the above technical solution, the motor drives the driven gear through the driving gear, and the driven gear drives the driving shaft.

[0012] Optionally, the motor is a reduction motor having a worm gear reducer.

[0013] By adopting the above technical solution, the worm gear reducer has a braking effect. When the motor stops running, it is difficult for the shock absorber to drive the drive shaft to rotate in the reverse direction, so that the shock absorber is easy to disassemble.

[0014] Optionally, the sliding direction between the two sliding brackets and the rack is horizontal.

[0015] Oil leakage is a common failure during the use of shock absorbers. Correspondingly, oil leakage is also a common failure form in the seismic resistance testing of shock absorbers. By adopting the above technical solution, the sliding direction between the sliding bracket and the frame is set to be in the horizontal direction. When the shock absorber has an oil leakage problem during the seismic resistance testing, the oil is not easy to flow along the shock absorber and the sliding bracket to the loading mechanism, which is conducive to reducing the cleaning work of the seismic resistance testing device.

[0016] Optionally, the two cranks are located on the same side of the drive shaft, and the two sliding brackets are located on both sides of the drive shaft respectively.

[0017] By adopting the above technical solution, when the sliding direction of the sliding bracket is set horizontally, the two sliding brackets are respectively set on both sides of the driving shaft, which can make the two sliding brackets staggered with a larger spacing distance, which is beneficial to disperse the jitter points of the two shock absorbers during seismic testing.

[0018] Optionally, the frame is provided with two oil receiving grooves, the two oil receiving grooves correspond to two detection fixtures respectively, and the oil receiving grooves are located below the corresponding detection fixtures.

[0019] By adopting the above technical solution, the oil receiving tank can receive the oil leaked due to failure during the anti-seismic testing of the shock absorber, which is conducive to the cleanliness of the working environment.

[0020] Optionally, oil absorbing cotton is provided in the oil receiving groove.

[0021] By adopting the above technical solution, the oil-absorbing cotton can absorb the oil leaked from the shock absorber, and the oil in the oil receiving tank can be quickly removed by replacing the oil-absorbing cotton, making the cleaning of the oil receiving tank more convenient.

[0022] Optionally, the oil collecting trough includes a bottom plate, a transverse side plate and a longitudinal side plate, two longitudinal side plates are provided, the two longitudinal side plates and the transverse side plates form a semi-enclosed structure, and the bottom plate gradually tilts upward in a direction away from the transverse side plates.

[0023] By adopting the above technical scheme, the two longitudinal side plates and the transverse side plates form a semi-enclosed structure, the high side of the bottom plate is opened, and a low-lying area for accumulating oil is formed between the bottom plate and the transverse side plates of the oil collecting trough. When cleaning the oil collecting trough, the oil at the bottom of the oil collecting trough can be directly scraped out from the high side of the bottom plate, making the cleaning of the oil collecting trough more convenient.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The loading directions of the two cranks of the shock absorber anti-vibration detection device are opposite, which can make the two cranks form a mutual balance effect to a certain extent, which is beneficial to reduce the vibration of the loading mechanism. In addition, when the energy released by one shock absorber can be used as the energy to drive the loading of the other shock absorber, it is beneficial to improve the energy utilization efficiency.

[0025] 2. When the driving shaft drives the crank to rotate, the crank reinforcing arm rotates synchronously with the crank, and the crank and the reinforcing arm respectively support the two sides of the sliding seat, which can make the movement of the sliding seat more stable.

[0037] The implementation principle of a shock absorber anti-seismic detection device according to an embodiment of the present application is as follows: when using the shock absorber anti-seismic detection device for anti-seismic detection, two shock absorbers are respectively installed on two detection fixtures 2. The motor 31 drives the drive shaft 34 to rotate, and the drive shaft 34 drives the two sliding seats 323 to rotate at the same time through the two cranks 33. The rotational motion of the sliding seats 323 is decomposed into two vertical linear motions, thereby driving the detection fixture 2 to repeatedly apply pressure to the shock absorber. The loading directions of the two cranks 33 are opposite, which can make the two cranks 33 form a mutual balance effect to a certain extent, which is conducive to reducing the shaking of the loading mechanism 3, and when the energy released by one of the shock absorbers can be used as energy to drive the loading of the other shock absorber, it is conducive to improving the efficiency of energy utilization.

[0038] Example 2 Reference Figure 3 The difference between this embodiment and the first embodiment is that the sliding direction between the sliding bracket 32 ​​and the frame 1 in this embodiment is set in the horizontal direction. The two cranks 33 are located on the same side of the driving shaft 34, and the two sliding brackets 32 are respectively located on both sides of the driving shaft 34. The sliding direction between the two sliding brackets 32 and the frame 1 is in the horizontal direction, and the guide column and guide sleeve assembly 322 on the sliding bracket 32 ​​is set horizontally.

[0039] The frame 1 is provided with two oil receiving grooves 5, the two oil receiving grooves 5 correspond to two detection fixtures 2 respectively, and the oil receiving grooves 5 are located below the corresponding detection fixtures 2. The oil receiving groove 5 includes a bottom plate 51, a horizontal side plate 52 and a vertical side plate 53, two vertical side plates 53 are provided, and the two vertical side plates 53 and the horizontal side plates 52 form a semi-enclosed structure, the bottom plate 51 gradually tilts upward in the direction away from the horizontal side plate 52, and a low-lying area capable of accumulating oil is formed between the low side of the bottom plate 51 and the horizontal plate, and oil-absorbing cotton 6 is provided in the oil receiving groove 5.

[0040] The sliding direction between the sliding bracket 32 ​​and the frame 1 is set to be in the horizontal direction. When the shock absorber leaks oil during the anti-seismic detection process, the leaked oil directly falls into the oil receiving groove 5, so that the oil is not easy to flow along the shock absorber and the sliding bracket 32 ​​to the loading mechanism 3, thereby helping to reduce the cleaning work of the anti-seismic detection device. The oil-absorbing cotton 6 in the oil receiving groove 5 can absorb the oil. By replacing the oil-absorbing cotton 6, the cleaning of the oil can be more convenient and the splashing of the oil can be reduced.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
