It can simulate road environments of different conditions for the quality testing of automobile shock absorbers. The height of each obstacle can be set according to actual needs. When passing through obstacles and test plates, the wheel assembly encounters obstacles before and after, simulating the force on the shock absorber in the process of the vehicle encountering obstacles and falling from the obstacles to the ground, thereby simulating actual road conditions, effectively simulating the movement of the wheel assembly close to the actual situation, and obtaining practical test results.

[0042] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0044] In this embodiment, the entry action of the front wheel assembly 1 to be tested into the speed-up runway 31 can be performed by the steering action of the front wheel assembly 1 to be tested and the lateral movement action of the tripod 2 on the ground rail 11. Since the simulated truncated cone 3 is a cylindrical structure and the actual road surface tends to be horizontal, the diameter of the simulated truncated cone 3 is much larger than the diameter of the wheel. The front wheel assembly 1 to be tested is placed horizontally and the wheel is in contact with the lowest point of the inner curved surface of the simulated truncated cone 3, which can greatly eliminate the adverse effect of this factor on the simulation detection.

[0045] Example

[0046] according to Figure 1 - Fig.11 ,like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a quality inspection device for automobile shock absorber processing, comprising a front wheel assembly 1 to be inspected and a ground rail 11,

[0047] It also includes a tripod bracket 2 slidably arranged on the ground rail 11, a driving assembly connected to the tripod bracket 2 is arranged on the ground rail 11, and the tripod bracket 2 is controlled to translate on the ground rail 11, the tripod bracket 2 includes a fixed base frame 21, a movable side frame 22 and a supporting ring rail 23, the fixed base frame 21 is fixedly connected to the supporting ring rail 23, the movable side frame 22 is slidably connected to the supporting ring rail 23, two movable side frames 22 are provided, and the movable side frames 22 are plugged into the fixed base frame 21;

[0048] A simulation truncated table 3 is rotatably connected to the inside of the support ring rail 23, wherein a speed-up runway 31 is arranged in the middle of the simulation truncated table 3, and a plurality of detection runways 32 are arranged on both sides of the inside of the simulation truncated table 3. The steering assembly on the front wheel assembly 1 to be detected can be controlled to cooperate with the triangular bracket 2 to translate on the ground rail 11. When the simulation truncated table 3 rotates, the steering movement of the wheel assembly on the simulation truncated table 3 is completed, and the displacement of the wheel assembly can be flexibly controlled between the speed-up runway 31 and the detection runway 32. A movable runway 33 is slidingly arranged on the simulation truncated table 3, and different types of obstacles can be arranged on the movable runway 33. The detection runway 32 is provided with an movable window 34, and the movable window 34 is located on the detection runway 32. When the movable runway 33 slides outside the simulation truncated table 3, the movable window 34 can be triggered to open, so that the obstacles arranged in the movable runway 33 are combined with the obstacles in the detection runway 32 to form a simulation runway with multiple obstacle types;

[0049] A clamping structure 4 is provided on the movable side frame 22 for limiting the position of the movable runway 33, so that the movable runway 33 maintains a stable relative position with the simulation round table 3 when rotating;

[0050] A transmission rod 12 is arranged in the middle of the simulation truncated table 3, and a slide cylinder 1201 is slidably sleeved on the outer wall of the transmission rod 12. The outer part of the slide cylinder 1201 is transmission-connected with the inner wall of the simulation truncated table 3. One end of the transmission rod 12 is connected to an external power component, so that when the transmission rod 12 rotates, the transmission control slide cylinder 1201 and the simulation truncated table 3 rotate. At the same time, when the simulation truncated table 3 moves with the translation of the tripod bracket 2, the transmission effect of the transmission rod 12 on the simulation truncated table 3 is still maintained;

[0051] The movable plug structure 5 is used to limit the sliding direction of the movable runway 33. The movable runway 33 can rotate synchronously with the simulated round table 3 through the movable plug structure 5. The movable plug structure 5 also guides the sliding movement of the movable runway 33.

[0052] The locking structure 6 is used to pull the movable runway 33 to slide outside the simulation truncated table 3. The sliding action of the movable runway 33 outside the simulation truncated table 3 is controlled by the locking structure 6, so as to provide power for the movable runway 33 to pass through the movable window 34 and the detection runway 32 to form a multi-obstacle type simulation runway and the reset action. When the plug-in relationship between the locking structure 6 and the movable runway 33 is established and the restriction of the movable plug-in structure 5 on the movable runway 33 is released, the simulation truncated table 3 is separated from the movable runway 33 and rotates independently, so as to adjust the relative position of the obstacles on the movable runway 33 and the movable window 34.

[0053] like Figure 3 - Figure 5In the embodiment, two sliding grooves 2301 are provided on the support ring rail 23, which are used to limit the sliding range of the movable side frame 22 on the support ring rail 23. A No. 1 electric telescopic rod 2204 is rotatably connected between the top ends of the two movable side frames 22. The No. 1 electric telescopic rod 2204 has a self-locking function, which limits the movement of the movable side frame 22 on the support ring rail 23 and fixes the position of the movable side frame 22. The inner and outer parts of the clamping structure 4 are connected separately, and the outer docking structure of the clamping structure 4 is installed on the fixed base frame 21 and the movable side frame 22. The inner docking structure of the clamping structure 4 is installed on the movable runway 33. The movable side frame 22 includes:

[0054] A movable bracket 2201 slidably connected to the sliding groove 2301, wherein the movable bracket 2201 is fixedly connected to the external docking structure of the clamping structure 4;

[0055] An inner sliding rod 2202 slidably sleeved inside the movable bracket 2201;

[0056] An inserting cylinder 2203 fixedly connected to the fixed base frame 21, wherein the bottom end of the inner sliding rod 2202 is inserted into the inserting cylinder 2203;

[0057] Rotate the second electric telescopic rod 2205 connected between the fixed base frame 21 and the inner slide rod 2202;

[0058] A backing plate 2206 fixedly connected between the two movable brackets 2201;

[0059] The top of the movable bracket 2201 is rotatably connected to the first electric telescopic rod 2204. Figure 5In the embodiment, the sliding of the movable side frame 22 on the supporting ring rail 23 is carried out through the coordinated control of the No. 1 electric telescopic rod 2204 and the No. 2 electric telescopic rod 2205. First, the No. 2 electric telescopic rod 2205 is started to extend, so that the output end of the No. 2 electric telescopic rod 2205 drives the inner sliding rod 2202 and the pad 2206 to move in the direction close to the movable bracket 2201. After the inner sliding rod 2202 is pulled out of the insertion tube 2203 for a distance and the pad 2206 abuts against the movable bracket 2201, the No. 1 electric telescopic rod 2204 is started to retract. At this time, the output end of the No. 2 electric telescopic rod 2205 can drive the pad 2206 to push the movable bracket 2201 to move upward. Synchronously, the No. 1 electric telescopic rod 2204 shrinks the interval between the two movable brackets 2201, so that the movable bracket 2201 moves along the sliding groove 2301 on the supporting ring rail 23. By sliding on the outer wall of the ring rail 23, the movable bracket 2201 can drive the clamping structure 4 to move, so that the interval between the clamping structure 4 on the movable side frame 22 and the clamping structure 4 on the fixed base frame 21 is increased to detach from the internal docking structure installed on the movable runway 33. At this time, the restriction of the clamping structure 4 on the simulation round table 3 can be released, and when the external docking structure and the internal docking structure of the clamping structure 4 need to restrict the position of the simulation round table 3 again, the No. 1 electric telescopic rod 2204 is controlled to extend and the No. 2 electric telescopic rod 2205 is controlled to contract to cooperate so that the movable bracket 2201 and the inner sliding rod 2202 can be reset, and after the inner sliding rod 2202 is reconnected with the plug-in tube 2203 installed on the fixed base frame 21, the two movable brackets 2201 and the fixed base frame 21 can cooperate again to tighten the support ring rail 23;

[0060] like Figure 1 , Figure 6 - Figure 8 In the figure, a plurality of terrain simulation chambers 3301 are arranged on the movable runway 33, and inclined grooves 3302 are arranged on both sides of the terrain simulation chambers 3301. The inclined grooves 3302 are all opened on the inner wall of the movable runway 33. The inclined grooves 3302 are used to trigger the opening of the movable window 34 when the movable runway 33 is translated outside the simulation truncated table 3. Different obstacles can be arranged in the terrain simulation chamber 3301. After the movable plug-in structure 5 releases the guide restriction on the movable runway 33, the locking structure 6 can be plugged with the movable runway 33, so that the simulation truncated table 3 can rotate independently relative to the movable runway 33, and the terrain simulation chamber 3301 opposite to the movable window 34 can be switched;

[0061] like Figure 6 - Figure 8 In the embodiment, the clamping structure 4 comprises:

[0062] A snap ring 41 fixedly connected to the outside of the movable runway 33;

[0063] Three protruding slideways 42 are respectively installed on the outside of the clamping ring 41;

[0064] Three docking slideways 43 are fixedly connected to the fixed base frame 21 and the movable side frame 22, wherein the length of two of the protruding slideways 42 is longer than that of the other protruding slideway 42. When the clamping ring 41 follows the movable runway 33 to rotate in the tripod bracket 2, the protruding slideway 42 can slide inside the docking slideway 43, thereby limiting the movable runway. When the two movable side frames 22 gather upward outside the supporting ring rail 23, they drive the docking slideway 43 to move, so that the two longer protruding slideways 42 can follow the movable runway 33 outside the simulation round table 3 and slide through the interval between the two docking slideways 43 on the fixed base frame 21 and the movable side frame 22, that is, the limit of the movable runway 33 by the clamping structure 4 is released;

[0065] Each of the docking slideways 43 is provided with a plurality of mirror images, and all are used to limit the movable runway 33, so that the movable runway 33 can be limited by the clamping structure 4 after being adjusted to different positions;

[0066] like Figure 6 and Figure 8 In the embodiment, the movable plug structure 5 comprises:

[0067] A plug-in rod 51 movably plugged into the movable runway 33, wherein both ends of the plug-in rod 51 are movably plugged into the outer side wall of the simulated frustum 3;

[0068] A movable piece 52 fixedly connected to one end of the plug rod 51;

[0069] A pull-out plate 53 slidably sleeved on the outside of the first movable plate 52;

[0070] A connecting plate 55 fixedly connected to the pull plate 53, wherein the middle portion of the connecting plate 55 is sleeved on the outside of the slide cylinder 1201;

[0071] The third electric telescopic rod 56 is fixedly connected to the middle part of the connecting plate 55, and the other end of the third electric telescopic rod 56 is rotatably mounted on the outer wall of the slide 1201. When the movable runway 33 is combined with the detection runway 32 through the movable window 34 to form a simulated runway of multiple obstacle types, since the movable runway 33 rotates with the simulated truncated table 3 through the movable plug-in structure 5, it is necessary to release the connection relationship between the movable plug-in structure 5 and the movable runway 33 in advance, and establish a plug-in relationship between the locking structure 6 and the movable runway 33. First, the third electric telescopic rod 56 is started to contract, and the pull-out plate 53 is driven to move away from the simulated truncated table 3 by pulling the connecting plate 55, so that the pull-out plate 53 pulls the first movable plate 52 and the plug-in rod 51 to move, thereby pulling the plug-in rod 51 out of the movable runway 33. When the relative position of the movable runway 33 and the movable window 34 is adjusted later, the simulated truncated table 3 can be actively rotated while the movable runway 33 remains stationary.

[0072] like Figure 8 In the embodiment, a pull-out arc-shaped slide groove 54 is provided on the inner side wall of the pull-out plate 53, and the No. 1 movable piece 52 is slidably connected inside the pull-out arc-shaped slide groove 54. When the simulated truncated table 3 and the movable runway 33 rotate relative to each other, the No. 1 movable piece 52 can slide inside the pull-out arc-shaped slide groove 54, so that the pull-out plate 53 can subsequently drive the plug-in rod 51 to re-plug with the movable runway 33 and the simulated truncated table 3 through the No. 1 movable piece 52, and restore the sliding guide restriction of the plug-in rod 51 on the movable runway 33. When the simulated truncated table 3 rotates, the plug-in rod 51 continues to drive the movable runway 33 to rotate synchronously. In the subsequent rotation process of the movable runway 33, the No. 1 movable piece 52 can pass through the pull-out plate 53 through the pull-out arc-shaped slide groove 54 to avoid hindering the rotation of the simulated truncated table 3 and the movable runway 33.

[0073] like Figure 7 and Fig. 9 In the embodiment, the locking structure 6 comprises:

[0074] A mounting plate 61 fixedly mounted on the support ring rail 23;

[0075] A fourth electric telescopic rod 62 fixedly mounted on the mounting plate 61;

[0076] A second movable piece 63 fixedly connected to the output end of the fourth electric telescopic rod 62;

[0077] A plurality of L-shaped baffles 64 are fixedly connected to the movable runway 33, and the L-shaped baffles 64 are sleeved on the outside of the second movable piece 63. When the output end of the fourth electric telescopic rod 62 is extended, the second movable piece 63 is first plugged into the movable runway 33, and the movable runway 33 is driven to slide along the movable plug-in structure 5 on the outer wall of the simulated truncated table 3 by pushing the movable runway 33. When the output end of the fourth electric telescopic rod 62 is retracted, the second movable piece 63 pulls the movable runway 33 to slide along the movable plug-in structure 5 on the outer wall of the simulated truncated table 3 by pulling the L-shaped baffle 64. In addition, when the movable runway 33 rotates, the design of the L-shaped baffle 64 can effectively prevent the second movable piece 63 from hindering the rotation of the movable runway 33;

[0078] One side of the second movable piece 63 is provided with a matching locking groove 65, and the locking groove 65 is opened on the movable runway 33. When the fourth electric telescopic rod 62 pushes the movable runway 33, it is first inserted into the locking groove 65 to maintain a plug-in relationship with the movable runway 33, so as to more stably push the movable runway 33 to slide on the simulation round table 3, and when the movable runway 33 and the simulation round table 3 need to rotate relative to each other and adjust the relative relationship between the obstacle on the movable runway 33 and the movable window 34, the position of the movable runway 33 can be fixed by the plug-in relationship between the second movable piece 63 and the locking groove 65, so as to effectively prevent the movable runway 33 from passively rotating with the simulation round table 3 when the movable plug-in structure 5 releases the restriction on the movable runway 33;

[0079] like Fig.10 and Fig.11 In the embodiment, the acceleration runway 31 and the detection runway 32 are assembled by movably installing a plurality of runway plates on the simulation round table 3, so that it is more convenient to inspect, replace or rearrange the obstacle content on the detection runway 32. The movable window 34 includes:

[0080] Two symmetrically arranged movable leaf plates 3401 are slidably mounted on the runway plate;

[0081] A slide bar 3402 fixedly connected to the outer wall of the movable leaf plate 3401, one end of the slide bar 3402 penetrates and is slidably connected to the runway plate, and a return spring is fixedly connected between the movable leaf plate 3401 and the runway plate;

[0082] When the movable runway 33 slides outside the simulated truncated table 3, the portion of the slide bar 3402 extending out of the runway plate can slide along the inclined groove 3302, thereby driving the two movable leaf plates 3401 to passively separate from each other;

[0083] like Figure 1 and Figure 3In the embodiment, an inner support 1202 is fixedly connected between the outer wall of the slide cylinder 1201 and the inner wall of the simulated truncated cone 3 .

[0084] In this embodiment, when the shock absorber force data of the front wheel assembly 1 to be detected is detected on different detection tracks 32 at different simulation speeds, the transmission rod 12 is driven to rotate by an external driving source, and the transmission rod 12 drives the simulation round table 3 to rotate in the support ring track 23 through the slide cylinder 1201 and the inner support 1202, and the relative speed between the obstacle on the detection track 32 and the front wheel assembly 1 to be detected is increased by accelerating the rotation of the acceleration track 31, and the front wheel assembly 1 to be detected is controlled to turn to the detection track 32 on the side of the acceleration track 31, and at the same time, the triangular bracket 2 is controlled to translate on the front wheel assembly 1 to be detected, so as to cooperate with the front wheel assembly 1 to be detected. The assembly 1 moves quickly to the detection runway 32. When the front wheel assembly 1 to be detected passes over an obstacle on the detection runway 32, the collision between the obstacle and the front wheel assembly 1 to be detected at a relatively preset speed can simulate the movement of the front wheel assembly 1 to be detected when passing over an obstacle on an actual road, which is consistent with the actual force condition of the shock absorber, reduces the error of the detection data, and makes the detection data more reliable. After the detection is completed, the steering of the front wheel assembly 1 to be detected and the movement of the triangular bracket 2 can be controlled again to make the wheel return to the acceleration runway 31. The force detection of the shock absorber at different speeds can be performed by changing the preset speed of the simulation round table 3.

[0085] The force on the shock absorber can also be detected by replacing the wheel on a different detection runway 32 so that the wheel passes through different types of obstacles: a raised obstacle is arranged on the detection runway 32 on the side of the simulated truncated table 3 away from the front wheel assembly 1 to be detected, and a recessed obstacle is arranged on the side of the simulated truncated table 3 close to the front wheel assembly 1 to be detected. The force on the shock absorber can be detected when the wheel passes through the recessed obstacle and the raised obstacle. In addition, the detection data of the front wheel assembly 1 to be detected passing through the raised obstacle at different speeds relative to the simulated truncated table 3 and the force on the shock absorber can be detected.

[0086] There are recessed obstacles of different depths arranged at intervals in the terrain simulation chamber 3301. When it is necessary to combine the movable runway 33 and the detection runway 32 with raised obstacles (the detection runway 32 on the side away from the front wheel assembly 1 to be detected) into a simulated road with multiple obstacle types: start the No. 2 electric telescopic rod 2205 to push the inner slide bar 2202 to first withdraw the insertion cylinder 2203, so that the movable side frame 22 is separated from the fixed bottom frame 21, and then start the No. 1 electric telescopic rod 2204 to release the self-locking and slowly retract, and the inner slide bar 2202 continues to move, so that the pad 2206 pushes the movable bracket 2201 to move, so that the two movable brackets 22 01, the top of the movable bracket 2201 is gathered together, and after the movable bracket 2201 slides to the other end along the sliding groove 2301, at this time, the gap between the docking slide 43 and the fixed base frame 21 is greater than the length of the two longer protruding slides 42, and the protruding slides 42 are all separated from the docking slide 43. At this time, the output end of the fourth electric telescopic rod 62 is started to push the movable runway 33 to slide toward the detection runway 32 on the other side. During the sliding process of the movable runway 33 along the plug-in rod 51, the sliding rod 3402 enters the movable runway 33 and slides along the inclined groove 3302. The two sliding rods 3402 simultaneously drive the two movable leaf plates 3401 to unfold on the runway plate. , so that the movable window 34 on the detection runway 32 is opened, and the terrain simulation chamber 3301 now displays the recessed obstacles arranged inside through the movable window 34, so that the detection runway 32 on one side is combined into a simulation runway with raised obstacles and recessed obstacles, and then the movable side frame 22 is controlled to reset, and the No. 1 electric telescopic rod 2204 is started to extend, and the No. 2 electric telescopic rod 2205 is started to contract, pushing the movable brackets 2201 on both sides to move away from each other. When the movable bracket 2201 slides to another section in the sliding groove 2301, the inner sliding rod 2202 is aligned with the insertion tube 2203, and the No. 1 electric telescopic rod is locked at this time 2204 length, the second electric telescopic rod 2205 continues to shrink, so that the inner slide rod 2202 is gradually inserted into the insertion tube 2203, so that the movable bracket 2201 is plugged into the fixed bottom frame 21. During the resetting process of the movable side frame 22, the mutual separation action of the movable bracket 2201 synchronously drives the docking slide 43 to slide and plug on the protruding slide 42, and locks the plane where the movable runway 33 rotates. It can enrich the types of simulated runway obstacles and detect the force data of the shock absorber when the wheels pass continuously at different speeds, simulating the actual force of the shock absorber when the front wheel assembly 1 to be tested actually passes through a complex terrain road surface;

[0087] In addition, when it is necessary to switch the terrain simulation chamber 3301 through the movable window 34 to enrich the combined road obstacle simulation runway, the movable runway 33 is first reset. During the reset operation, the docking slide 43 is first separated from the protruding slide 42, and then the L-shaped baffle 64 is pulled by the fourth electric telescopic rod 62 and the second movable piece 63 to drive the simulation round table 3 to reset, and then the fourth electric telescopic rod 62 is controlled to extend, driving the second movable piece 63 to insert into the locking groove 65 to limit the rotation of the movable runway 33. At this time, the third electric telescopic rod 56 is started to make the connecting plate 55 move away from the movable runway 33 by pulling the arc-shaped slide groove 54, so that the plug-in rod 51 is pulled out. The movable runway 33 is separated from the movable runway 33, and then the simulation frustum 3 is controlled to rotate so that the simulation frustum 3 is relatively rotated inside the movable runway 33, and the position of the terrain simulation warehouse 3301 relative to the movable window 34 is switched. Then the pull-out plate 53 is controlled to push the plug-in rod 51 to be plugged with the movable runway 33 again through the No. 1 movable piece 52, and the movable runway 33 is pushed to move to the outside of the detection runway 32 on one side through the No. 4 electric telescopic rod 62 and the No. 2 movable piece 63. Then, after the movable side frame 22 is reset, the docking slide 43 and the protruding slide 42 are used again to limit the plane where the movable runway 33 is rotated, and the terrain simulation warehouse 3301 through the movable window 34 can be switched to enrich the combined road obstacle simulation runway.
