Description

Technical Field

[0001] The utility model belongs to the technical field of shock-absorbing air bag testing, and in particular relates to a shock-absorbing air bag testing tool. Background Art

[0002] The shock-absorbing air bag is a shock-absorbing structure on the car, which belongs to the pneumatic shock-absorbing device. During the working process, the gas in the shock-absorbing air bag is used to achieve the excellent buffering effect of the shock-absorbing air bag when the vehicle is in a bumpy state, thereby improving the driving experience of the vehicle.

[0003] During the production process of shock-absorbing air bags, it is necessary to test the air tightness of the shock-absorbing air bags. The specific testing method is to put the shock-absorbing air bags into water. When the shock-absorbing air bags leak, bubbles are generated in the water, indicating that the air tightness of the shock-absorbing air bags is relatively poor.

[0004] However, due to the special-shaped structure of the shock-absorbing air bag, during the inspection process, the operator holds the shock-absorbing air bag in the water for inspection and fishes it out after inspection. The disadvantages of this method are: first, only one shock-absorbing air bag can be inspected at a time, and it is not easy to adjust the angle of the shock-absorbing air bag during the inspection process to facilitate the determination of the leak location. Secondly, during the inspection process, the heavy shock-absorbing air bag is difficult to support stably, resulting in the shock-absorbing air bag easily slipping from the hand during the inspection and the fishing process.

[0005] Moreover, the disadvantage of the above detection method is that the detection efficiency is too low, and the number of samples for sampling and testing of mass-produced shock-absorbing air bags is relatively large, so during the detection process, the base number of test samples is also large.

[0006] At the same time, the detection accuracy is relatively poor during the detection process in the water body. This is reflected in the fact that some shock-absorbing air bags with airtightness defects do not leak seriously when they are static, and the bubbles in the water body are relatively small and difficult to observe. When they shake and sway, the leakage worsens. However, current detection methods make it difficult to simulate the airtightness detection of the shock-absorbing air bags in a moving state. Utility Model Content

[0007] Based on the above background, the purpose of the utility model is to provide a shock-absorbing air bag testing tool.

[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0009] A shock-absorbing air bag test tool, comprising a shock-absorbing air bag air tightness test mechanism, wherein the shock-absorbing air bag air tightness test mechanism comprises a test water tank and a test fixture assembled and connected in the test water tank;

[0010] The test fixture comprises a horizontally arranged hollow fixture rod, and the hollow fixture rod is rotatably connected;

[0011] The hollow clamp rod is equipped with a plurality of shock-absorbing air bag locking structures at different heights, the shock-absorbing air bag locking structure comprises an inner locking sleeve mounted on the side wall of the hollow clamp rod, and the shock-absorbing air bag locking structure also comprises a locking plate matched with the inner locking sleeve;

[0012] An air bag sheath is fixedly connected to the inner side wall of the lock plate, and screw rods are slidably assembled and connected to both ends of the lock plate, and the screw rods are installed on the hollow clamp rod;

[0013] The screw rod is threadedly connected with a push nut which pushes the lock plate to contact and press the shock-absorbing air bag.

[0014] Preferably, the longitudinal cross-section of the hollow clamp rod is in a mouth shape, and a plurality of shock-absorbing air bag locking structures are fixedly mounted on the top, bottom, left side wall and right side wall of the hollow clamp rod.

[0015] Preferably, the inner locking sleeve includes a sleeve fixedly connected to the hollow clamp rod, the sleeve is threadedly connected to the locking sleeve, and the sleeve and the locking sleeve are both provided with guide discharge ports. When the sleeve coincides with the guide discharge ports on the locking sleeve, the air pipe on the shock-absorbing air bag is limited in the sleeve, and the locking sleeve is rotated until the guide discharge ports are offset to lock the inner end of the shock-absorbing air bag.

[0016] Preferably, the air bag sheath is in a trumpet shape, and its opening is a trumpet-shaped opening.

[0017] Preferably, end seat structures are respectively installed at the front and rear ends of the hollow clamp rod;

[0018] The end seat structure comprises an end seat, an inner hanging rod is fixedly connected inside the hollow clamp rod, and a plurality of connecting long screw rods fastened on the inner hanging rod are fixedly connected on the end seat.

[0019] Preferably, the shock-absorbing air bag testing tool further comprises a spring side sliding mechanism, and during the air tightness testing process, the shock-absorbing air bag is elastically shaken by the spring side sliding mechanism.

[0020] Preferably, the spring side sliding mechanism comprises a U-shaped frame fixedly connected to the front and rear sides of the top of the detection water tank, a horizontal slide bar is fixedly connected inside the U-shaped frame, and the spring side sliding mechanism also comprises a slide seat fixedly connected to the end seat, and the slide seat is slidably connected to the horizontal slide bar;

[0021] Two sections of springs are sleeved on the horizontal sliding rod, and two sides of the springs are respectively fixedly connected to the U-shaped frame and the sliding seat.

[0022] Preferably, the slide seat is cylindrical in shape, a rotating shaft is mounted on the slide seat, and the rotating shaft is rotatably connected to the end seat.

[0023] Preferably, the test water tank is respectively equipped with a water inlet pipe and a foam agent inlet pipe.

[0024] The utility model has the following beneficial effects:

[0025] 1. During the testing process, when the hollow fixture rod is rotated, the multiple shock-absorbing air bags at the bottom layer that have been immersed in water are first tested. At this time, the rotation method is used to switch the multiple shock-absorbing air bags at adjacent positions to be immersed in water for testing. This method improves the testing efficiency. During the testing process, a certain number of samples can be tested quickly and accurately.

[0026] 2. The overlap of the guide discharge port on the lap sleeve and the locking sleeve is achieved. This method is convenient for placing the air pipe at the inner end of the shock-absorbing air bag (the air pipe on the shock-absorbing air bag is installed on the vehicle body) in the lap sleeve, and locking the inner end of the shock-absorbing air bag after rotating the locking sleeve until the guide discharge port is staggered. Specifically, a closed locking structure is formed after the locking sleeve guide discharge port is staggered, and after detection, the locking sleeve is rotated until the discharge port overlaps, so that it is easy to disengage. This method makes it easy to clamp and load the shock-absorbing air bag.

[0027] 3. During the test, pull the hollow clamp rod to one side, such as to the right. At this time, the spring on the right is compressed and the spring on the left is stretched. At this time, release the hollow clamp rod. When the external force disappears, the shock-absorbing air bag locked on the hollow clamp rod slides elastically left and right under the action of the springs on both sides. This method simulates whether the shock-absorbing air bag will leak under bumpy and unstable speed conditions.

[0028] The above-mentioned detection method can realize accurate detection of shock-absorbing air bags, and unqualified and leaking shock-absorbing air bags can be detected and screened out quickly and accurately. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1

[0041] like Figure 1-6As shown, a shock-absorbing air bag testing tool includes a shock-absorbing air bag air tightness testing mechanism, and the shock-absorbing air bag air tightness testing mechanism includes a test water tank 1 (according to the existing method, a water inlet pipe and a foam inlet pipe 11 are respectively assembled and connected to the test water tank, and a valve is installed on the pipe. During the detection process, the foam agent is pumped in, and larger bubbles are generated by gas and foam agent to achieve convenient observation, especially when the leakage is relatively weak, this method can achieve clear observation) and a test fixture assembled and connected in the test water tank 1.

[0042] Specifically, the test fixture includes a horizontally arranged hollow fixture rod 21, and the longitudinal cross-section of the hollow fixture rod 21 is a mouth shape. The hollow fixture rod 21 is rotatably connected to realize switching of the shock-absorbing air bag 4 at different positions during the testing process.

[0043] Specifically, a plurality of shock-absorbing air bag locking structures at different heights are assembled and connected to the hollow clamp rod 21. Specifically, a plurality of shock-absorbing air bag locking structures are fixedly assembled on the top, bottom, left side wall and right side wall of the hollow clamp rod 21.

[0044] When the hollow clamp rod 21 is rotated, the multiple shock-absorbing air bags 4 at the bottom layer that have been immersed in the water are first tested. At this time, the rotation method is used to switch the multiple shock-absorbing air bags 4 at adjacent positions to be immersed in the water for testing. This method improves the testing efficiency. During the testing process, a certain number of samples can be tested quickly and accurately.

[0045] In order to lock and position the shock-absorbing air bag, the shock-absorbing air bag locking structure includes an inner locking sleeve 22 installed on the side wall of the hollow clamp rod 21 , and the shock-absorbing air bag locking structure also includes a locking plate 24 matched with the inner locking sleeve 22 .

[0046] Specifically, an air bag cover 25 is fixedly connected to the inner wall of the locking plate 24 (the shape of the air bag cover 25 is trumpet-shaped, and its opening is a trumpet-shaped opening. Specifically, the shape of the air bag cover 25 is the same as the shape of the outer end b of the shock-absorbing air bag. The outer end b has a large diameter and is adapted after the air bag cover 25 is snapped in. When the U-shaped locking plate 24 is pushed inward to the air bag cover 25, it is inserted into the outer end shell of the shock-absorbing air bag 4 to achieve locking).

[0047] The specific method is as follows: the two ends of the locking plate 24 are respectively slidably assembled with screw rods 23, which are installed on the hollow clamp rod 21; the screw rod 23 is threadedly connected with a pushing nut 231 that pushes the locking plate 24 to contact and lock the shock-absorbing air bag 4.

[0048] During operation, the locking plate 24 is pushed inwardly and locked by twisting the push nut inwardly.

[0049] In the above manner, during the detection process, multiple shock-absorbing gases are synchronously locked and positioned, and batch detection is completed during the continuous rotation and switching process.

[0050] Example 2

[0051] like Figure 1-5 As shown, based on the structure of Example 1, in order to facilitate the removal of the shock-absorbing gas after testing, the inner locking sleeve 22 includes a sleeve 221 fixedly connected to the hollow clamp rod 21 (the outer wall of the sleeve 221 is provided with a threaded structure), the sleeve 221 is threadedly connected with a locking sleeve 222 (the inner wall of the locking sleeve 222 is provided with an adaptive threaded structure), and the sleeve 221 and the locking sleeve 222 are both provided with a guide discharge port, when the sleeve 221 and the guide discharge port on the locking sleeve 222 coincide. In this way, it is convenient to carry and limit the air pipe a at the inner end of the shock-absorbing air bag 4 in the sleeve 221, and rotate the locking sleeve 222 until the guide discharge port is staggered to lock the inner end of the shock-absorbing air bag 4.

[0052] Specifically, the locking sleeve 222 is rotated to guide the discharge port to stagger to form a closed locking structure, and after detection, the locking sleeve 222 is rotated to overlap the discharge port to achieve convenient disengagement.

[0053] The discharge port on the locking sleeve 222 is integrally formed with an inclined surface structure 2221 of an inclined setting portion, and the inclined surface structure 2221 facilitates the air pipe a at the inner end position of the shock-absorbing air bag 4 to be guided and slid in.

[0054] Example 3

[0055] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, end seat structures are respectively installed at the front and rear ends of the hollow clamp rod 21.

[0056] Specifically, the end seat structure includes a circular end seat 33 (the specific rotational connection method of the hollow clamp rod 21 is: a rotating shaft A is installed on the following sliding seat 34, and according to the existing rotational connection method, the rotating shaft A is rotationally connected to the end seat 33), the hollow clamp rod 21 is fixedly connected with an inner hanging rod 31, and the end seat 33 is fixedly connected with two long connecting screws 32 fastened to the inner hanging rod 31 (for easy disassembly).

[0057] At the same time, the shock-absorbing air bag test tooling also includes a spring side sliding mechanism. During the air tightness test, the shock-absorbing air bag is elastically shaken through the spring side sliding mechanism.

[0058] Specifically, the spring side sliding mechanism is used to simulate whether the shock absorbing air bag 4 will leak during its movement. If the connecting hoop on the shock absorbing air bag 4 is not locked tightly enough, it is easy to leak slightly when the vehicle is bumpy.

[0059] Specifically, the spring side-sliding mechanism includes a U-shaped frame 35 fixedly connected to the front and rear sides of the top of the detection water tank, and a horizontal sliding rod 36 is fixedly connected inside the U-shaped frame 35. The spring side-sliding mechanism also includes a slide 34 fixedly connected to the end seat 33 (the slide 34 is cylindrical in shape, and a rotating shaft A is installed on the slide 34, and the rotating shaft A is rotatably connected to the end seat 33), and the slide 34 is slidably connected to the horizontal sliding rod 36.

[0060] Two sections of springs 37 are sleeved on the horizontal slide bar 36 , and two sides of the spring 37 are fixedly connected to the U-shaped frame 35 and the slide seat 34 respectively.

[0061] During the test, the hollow clamp rod 21 is pulled to one side, such as the right side. At this time, the spring 37 on the right side is compressed and the spring 37 on the left side is stretched. At this time, the hollow clamp rod 21 is released. When the external force disappears, under the action of the springs 37 on both sides, the shock-absorbing air bag locked on the hollow clamp rod 21 slides elastically left and right. In this way, whether the shock-absorbing air bag 4 will leak under bumpy and unstable speed conditions is simulated.

[0062] The above detection method can be used to accurately detect the shock-absorbing air bag 4, and unqualified and leaking shock-absorbing air bags can be quickly and accurately detected and screened out.

[0063] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
