Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber detection, in particular to a vehicle shock absorber airtightness detection device. Background Art

[0002] In the automotive manufacturing industry, shock absorbers are key components whose performance and quality are directly related to the vehicle's driving stability and ride comfort. The tightness of the shock absorber is one of the important indicators to measure its performance. If the tightness is poor, it will cause oil leakage inside the shock absorber, which will in turn affect the shock absorption effect and vehicle safety. Therefore, it is particularly important to conduct strict tightness testing on the shock absorber during the production process.

[0003] Chinese patent CN211147972U discloses an automobile shock absorber sleeve air tightness test device, including a housing, a telescopic arm, a control panel, a mounting seat, and a mounting beam. One end of the telescopic arm is vertically connected to the middle of the mounting beam. The bottom ends of the mounting beam are symmetrically provided with air injection ports, which are arranged in conjunction with the mounting seat. An air pump is provided at one end of the mounting beam. The mounting beam is internally provided with a cavity for accommodating a manifold and a control mechanism. The air pump's air filling port is connected to the cavity. The telescopic arm, air pump, and control mechanism are all connected to the control panel via wires. A precision micro-differential pressure sensor connected to the same air path of the test piece and the standard part measures the differential pressure value between the standard part and the test piece within a specified time, eliminating the influence of sealing leakage in the air filling air path or the air injection sealing port itself, thereby ensuring the accuracy of the test results.

[0004] When the above-mentioned equipment is testing the shock absorber sleeve, the test piece needs to be placed on the mounting seat and then tested. After the test is completed, the tested test piece needs to be taken out. During the testing and taking-out process, the waiting time for the next group of test pieces to be tested is long, the testing steps are relatively cumbersome, and the test pieces need to be frequently placed in or taken out, which is not convenient for testing the airtightness of the shock absorber sleeve in large quantities. The detection efficiency is low. In addition, the above-mentioned equipment is not convenient for separating good products and defective products. Utility Model Content

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations. Example 1

[0026] Please refer to Figures 1-4 As shown, a vehicle shock absorber tightness detection device includes a base plate 1, a water reservoir 101 is provided on the upper end of the base plate 1, a transfer mechanism 2 is installed on the upper end of the base plate 1, the transfer mechanism 2 includes a rotating shaft 204, the rotating shaft 204 is provided above the water reservoir 101, both ends of the rotating shaft 204 are fixedly connected to a cross mounting frame 205, a detection mechanism 3 is installed on the inner side of the cross mounting frame 205, and the detection mechanism 3 includes four groups of guide rods 309, which are fixedly connected to the Between the two groups of cross mounting frames 205, the two ends of the guide rod 309 are respectively slidably connected with sliders 305, and the upper ends of the two groups of sliders 305 are fixedly connected with splints 306. The inner side of one group of splints 306 is fixedly connected with an air nozzle 308. A classification component 4 is set on the left side of the cross mounting frame 205. The classification component 4 includes a good product box 401 and a defective product box 402. The good product box 401 is set on the left side of the support frame 201, and the defective product box 402 is set on the left side of the good product box 401.

[0027] In this embodiment, the water reservoir 101 stores aqueous solution, and an external delivery mechanism can deliver the shock absorber sleeve between the two sets of clamping plates 306. The two sets of clamping plates 306 move closer to each other to clamp and fix the shock absorber sleeve. At the same time, the air nozzle 308 is delivered to the inside of the shock absorber sleeve to inflate the inside of the shock absorber sleeve.

[0028] Furthermore, the rotating shaft 204 can drive the cross mounting frame 205 to intermittently rotate 90 degrees, thereby driving the detection mechanism 3 to rotate, so that the clamped shock absorber sleeve is moved into the water reservoir 101. At the same time, the external conveying mechanism conveys the next set of shock absorber sleeves to the adjacent detection mechanism 3 and clamps them. At the same time, the air nozzle 308 can send air into the interior of the shock absorber sleeve and pressurize it. At this time, it is left to stand for 5s-15s, and whether bubbles are generated on the water surface is observed. If bubbles are generated, it is determined that the shock absorber sleeve is not sealed as required. If no bubbles are generated, it is determined that the shock absorber is sealed well. The detection steps are simple and convenient.

[0029] Furthermore, by rotating the shaft 204 by another 90° rotation, the shock absorber sleeves can be transported to the side of the good product box 401, so that good products and defective products can be placed in different areas. At the same time, the next group of shock absorber sleeves are transported to the inner side of the water reservoir 101 for tightness testing. The cross mounting frame 205 and the testing mechanism 3 are driven by the shaft 204 to rotate intermittently, which can realize the operations of clamping and loading the shock absorber sleeves, testing the shock absorber sleeves, and placing them in different areas according to the test results, thereby improving the consistency of the test, thereby increasing the test efficiency of the shock absorber sleeves, and facilitating large-scale testing.

[0030] Furthermore, the two sets of clamps 306 move away from each other to release the fixed clamping of the shock absorber sleeve. The shock absorber sleeve that does not meet the requirements is transported to the inside of the defective box 402, and the good shock absorber sleeve is transported to the inside of the good box 401. Example 2

[0033] The detection mechanism 3 also includes four groups of bidirectional screws 303 and four groups of drive motors 304. The four groups of drive motors 304 are respectively fixedly mounted on the outside of one group of cross mounting frames 205. The four groups of bidirectional screws 303 are respectively rotatably connected between the two groups of cross mounting frames 205. The output end of the drive motor 304 extends to the inner side of the cross mounting frame 205 and is fixedly connected to the bidirectional screw 303. The two ends of the bidirectional screw 303 are respectively provided with threads and the rotation directions are opposite. The two groups of sliders 305 are respectively threadedly connected to the two ends of the bidirectional screw 303.

[0034] The detection mechanism 3 also includes an air pump 301 and an annular pipe 302. The air pump 301 is fixedly installed on the inner side of the cross mounting frame 205. The air pump 301 is connected to the annular pipe 302 through a pipe. The annular pipe 302 is connected to the air nozzle 308 through a connecting hose. An electromagnetic valve is provided inside the air nozzle 308.

[0035] A sealing gasket 307 is fixedly connected to the inner side of the clamping plate 306 located on one side of the air nozzle 308 .

[0036] In this solution, the drive motor 304 is electrically connected to the external power supply. The drive motor 304 can drive the bidirectional screw 303 to rotate, and then drive the two sets of sliders 305 to make the splints 306 approach or move away from each other. The air pump 301 is electrically connected to the external power supply. The air pump 301 can transport air from the annular pipe 302 to the air nozzle 308. When the lower end of the cross mounting bracket 205 rotates to the water reservoir 101, the solenoid valve opens, thereby performing inflation detection on the inside of the shock absorber cylinder, and the other three sets of solenoid valves are closed. Example 4

[0037] Please refer to Figure 4 As shown, the classification component 4 also includes a fixed table 403, which is arranged on the right side of the good product box 401.

[0038] A second inclined platform 406 is slidably connected to the inner side of the good product box 401, two sets of guide rails 405 are fixedly connected between the defective product box 402 and the good product box 401, the second inclined platform 406 is slidably connected to the guide rail 405, and a second electric push rod 408 is fixedly installed on the right side of the defective product box 402, and the output end of the second electric push rod 408 is fixedly connected to the second inclined platform 406 through a connecting plate.

[0039] In this solution, the first electric push rod 407 is electrically connected to the external power supply. The first electric push rod 407 can push the first inclined platform 404 to move to the lower end of the left side of the cross mounting frame 205, so that when the clamp 306 releases the fixation of the shock absorber sleeve, it can automatically fall on the upper end of the first inclined platform 404 and be guided by the first inclined platform 404 to the interior of the good product box 401. The second electric push rod 408 can drive the second inclined platform 406 to abut the right side of the inner wall of the good product box 401, thereby guiding the defective products from the upper end of the good product box 401 to the interior of the defective product box 402.

[0040] The working principle and use process of the present invention are as follows: First, the shock absorber sleeve is transported between the two sets of clamping plates 306 through the external conveying mechanism, and the driving motor 304 is started to drive the bidirectional screw 303 to rotate, thereby driving the two sets of sliders 305 to make the clamping plates 306 approach each other to clamp the shock absorber sleeve. At the same time, the air nozzle 308 is sent into the inner side of the shock absorber sleeve. After that, the stepper motor 202 is started to drive the rotating shaft 204 to rotate the cross mounting frame 205 90 degrees, so that the clamped shock absorber sleeve moves to the inside of the water reservoir 101. At this time, the air pump 301 is started to transport the gas to the inside of the shock absorber and pressurize it. By observing whether there are bubbles on the water surface, the good and defective shock absorber sleeves can be judged. At the same time, the external The boundary conveying mechanism conveys the next group of shock absorber sleeves to the adjacent detection mechanism 3. After the detection of the first group of shock absorber sleeves is completed, the rotating shaft 204 causes the cross mounting frame 205 to rotate 90° again, thereby moving the first group of shock absorber sleeves to the side of the good product box 401. At the same time, the next group of shock absorber sleeves are conveyed to the inner side of the water reservoir 101 for tightness detection. Afterwards, if the shock absorber sleeves are good products, only the first electric push rod 407 is started, and the shock absorber sleeves are guided to the inside of the good product box 401 by the first inclined platform 404. If the shock absorber sleeves are defective, the first electric push rod 407 and the second electric push rod 408 are started at the same time, so that the defective products can be directly conveyed from the first inclined platform 404 to the second inclined platform 406 to the inside of the defective box 402.
