DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] In order to effectively illustrate the embodiments of the present invention, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0034] Combination Figure 1 and Figure 2 The figure shows a structural schematic diagram of a rotating and lifting multifunctional test bench provided in an embodiment of the present application in a non-working state. Figure 1 This is a schematic diagram of the overall structure of the rotary lifting multifunctional test bench disclosed in this application. Figure 2This is a rotating and lifting multifunctional test bench disclosed in this application.

[0035] like Figure 1 and Figure 2 As shown, the present application discloses a rotary lifting multifunctional test bench, which is mainly used to test the shock absorber. The rotary lifting multifunctional test bench includes a test bench main structure 26. The test bench main structure 26 can be as shown in FIG. Figure 2 The structure is in the shape of "4", so as to ensure the stability of the whole structure. The main structure 26 of the test bench can be fixed to the table or the ground by bolts, etc., so as to realize the detection of the shock absorber. A workbench 16 is arranged on the main structure 26 of the test bench, and a lifting cylinder seat 15 is symmetrically arranged on the workbench 16. The lifting cylinder seat 15 is fixedly connected to the lifting electric cylinder 14, and the lifting cylinder seat 15 is fixed to the workbench 16 by bolts, so as to ensure the stability of the lifting electric cylinder 14.

[0036] In the specific implementation process, the free end of the lifting electric cylinder 14 is fixedly connected to the lifting seat 8, and the lifting rotating beam 6 is clamped and connected between the two relative lifting seats 8. The actuator 1 is detachably installed on the lifting rotating beam 6, and the lifting rotating beam 6 can be rotated, so as to realize the multi-angle detection of the shock absorber. Of course, the lifting rotating beam 6 can also achieve the purpose of multi-angle rotation by rotating with the lifting seat 8.

[0037] Of course, in the specific implementation process, it can also be combined with Figure 3 The specific structural view of the disclosed lifting and rotating beam is described in detail. Specifically, the lifting and rotating beam 6 includes a rotating part 20 and a fixed part 19 fixedly connected to the lifting seat 8, wherein two fixed parts 19 are provided, one end of the two fixed parts 19 is fixedly connected to the lifting seat 8 by bolts respectively, and the rotating part 20 is arranged in the middle of the two fixed parts 19. In the specific implementation process, the fixed part 19 and the rotating part 20 are correspondingly positioned to limit the position of the beam rotating support shaft 4, and the outer periphery of the beam rotating support shaft 4 is sleeved with the beam rotating flange 2 and the beam rotating support flange 3, the rotating part 20 of the lifting and rotating beam 6 is fixedly connected to the beam rotating flange 2, the fixed part 19 of the lifting and rotating beam 6 is fixedly connected to the beam rotating support flange 3, and the beam rotating support flange 3 is rotationally connected to the beam rotating flange 2.

[0038] The present application ensures that the fixed part 19 and the rotating part 20 of the lifting and rotating beam 6 are rotatably connected through the beam rotating support shaft 4, and through the rotating connection between the beam rotating flange 2 and the beam rotating support flange 3, the beam rotating flange 2 can be rotated along the beam rotating support flange 3, thereby driving the rotating part 20 to rotate, so that the actuator 1 can rotate at different angles, thereby realizing the detection of different angles of the shock absorber 11 to be tested. On the one hand, it can realize multi-angle detection of the shock absorber and improve the detection efficiency. On the other hand, it can also reduce the procurement cost of purchasing multiple devices for multi-angle detection of the shock absorber using multiple devices using existing technology.

[0039] In order to ensure the effective rotation of the beam rotating flange 2 and the beam rotating support flange 3, the present application can be combined with the attached Figure 4 To Attachment Figure 6 The relevant structure is described in the accompanying drawings, wherein Figure 4 It is a partial structural enlarged view of the rotating part 20, Figure 5 and attached Figure 6 They are schematic diagrams of the structures of the crossbeam rotating flange 2 and the crossbeam rotating support flange 3. As shown in the figure, the crossbeam rotating flange 2 is provided with a sliding mounting hole 22, which can be a threaded hole, and the sliding mounting hole 22 is arranged near the surface of the crossbeam rotating support flange 3. The crossbeam rotating support flange 3 is provided with a sliding groove 24 that matches the sliding mounting hole 22, and the sliding groove 24 is arranged through the crossbeam rotating support flange 3. The crossbeam rotating support flange 3 can be slidably matched with the sliding mounting hole 22 through a sliding rod passing through the sliding groove 24. Specifically, the sliding rod is slidably matched with the sliding groove 24, and the end of the sliding rod can be provided with a thread that matches the sliding mounting hole 22 to realize a threaded fixed connection between the two, so that when the crossbeam rotating flange 2 is rotated, the sliding rod is rotated along the sliding groove 24, so that the rotating part 20 can rotate relative to the fixed part 19.

[0040] Of course, in the specific implementation process, the sliding groove 24 can be an annular groove arranged concentrically with the beam rotation support flange 3, so that the rotating part 20 can be freely rotated. At the same time, the arrangement of the sliding mounting hole 22 and the sliding groove 24 is not limited to the above-mentioned method. The sliding mounting hole 22 can also be arranged on the beam rotation support flange 3, and the sliding groove 24 can be arranged on the beam rotation flange 2, so as to achieve the relative rotation of the two. Of course, the above is only an exemplary embodiment and is not limited to this. The mutual working mode and working state can also be processed according to the actual situation.

[0041] As attached to this application Figure 4-6The structural view shown is used as an example for explanation. There are two sliding grooves 24 disclosed in the present application. The two sliding grooves 24 are arranged near the periphery of the cross beam rotation support flange 3, and each sliding groove 24 can ensure that the rotating part 20 can achieve at least 0-90 degree rotation. The cross beam rotation flange 2 is provided with a threaded hole 25, and the cross beam rotation flange 2 is provided with a bolt through the threaded hole 25, and a rotation angle gear 9 is arranged on the bolt near the cross beam rotation support flange 3, and the rotation angle gear 9 is meshed with the cross beam rotation support flange 3. Of course, in the specific implementation process, a stop nut is also arranged at a position adjacent to the rotation angle gear 9, and the stop nut is spirally connected to the bolt, so as to prevent the cross beam rotation flange 2 from causing the rotation angle gear 9 to fall off during the rotation process. The setting of the rotation angle gear 9 can ensure the effective rotation of the cross beam rotation flange 2, avoid the situation of rapid rotation or inability to rotate, resulting in the inability to accurately control the angle of the rotating part 20, and thus the inability to accurately control the angle problem of the shock absorber test. On the other hand, it can also further control the accuracy problem of multi-angle adjustment.

[0042] Of course, in the specific implementation process, the top and bottom of the workbench 16 are vertically provided with guide support seats 13, and the guide support seats 13 provided at the top and bottom are arranged oppositely. Alternatively, the guide support seats 13 may be provided only at the bottom of the workbench 16, and the number of the guide support seats 13 is the same as the number of the fixing parts 19. The guide seat 12 may be fixed to the guide support seat 13 by fixing bolts, and a guide rod 23 is threadedly fixed between two opposite guide seats 12. The fixing part 19 is provided with a guide hole slidably connected to the guide rod 23, so that the fixing part 19 can be slidably connected to the guide rod 23. Further, under the action of the lifting electric cylinder 14 and the like disclosed in the above embodiment, the fixing part 19 of the lifting and rotating beam 6 can move along the guide rod 23 as the lifting and lowering of the lifting electric cylinder 14 is realized, and the structural arrangement of the guide rod 23, the guide seat 12 and the like can effectively ensure the stable lifting and lowering of the lifting and rotating beam 6 in the vertical direction, and avoid deviations such as lateral displacement, thereby affecting the subsequent test effect of the shock absorber.

[0043] During the specific implementation process, in order to ensure the test effect during the test process, it is necessary to ensure the stability between the rotating part 20 and the fixed part 19 and to ensure that the movement of other structures is not affected during the lifting and lowering of the rotating crossbeam 6. The present application also discloses the following implementation methods: A thrust cylinder 7 is provided on the fixed part 19 disclosed in the present application. The thrust cylinder 7 can adopt a 30KG three-link cylinder, which is not limited here. The telescopic rod of the thrust cylinder 7 is connected to the crossbeam locking device 5, and the crossbeam locking device 5 includes the following Fig. 9The wedge block 28 shown in the figure is slidably connected to the fixing portion 19. Specifically, the middle position of the fixing portion 19 can be set to an inclined structure matching the wedge block 28, and the wedge block 28 can slide in the fixing portion 19 to form a whole (as shown in the attached figure). Figure 8 As shown in FIG. 1 ), the wedge block 28 and the fixing portion 19 are both provided with through holes 27, and the through holes 27 of the two can form a bolt hole, so that the bolt passes through the bolt hole to lock the rotating portion 20. Of course, the above is only an exemplary description and does not represent the only implementation method of the present application, and will not be elaborated in detail here.

[0044] Of course, in the specific implementation process, please refer to the attached Figure 7 To Attachment Fig.11 The structural view of the rotating part 20 and the fixed part 19 further illustrates the lifting and rotating beam 6 disclosed in the embodiment of the present application. As shown in the accompanying drawings, the middle position of the rotating part 20 disclosed in the present application is provided with an actuator mounting hole 17 and an actuator rod mounting hole 18. The size of the actuator mounting hole 17 is larger than that of the actuator rod mounting hole 18. The actuator mounting hole 17 and the actuator rod mounting hole 18 are connected. The actuator 1 is installed in the actuator mounting hole 17. The actuator rod mounting hole 18 is used to install the test actuator rod 10. The free end of the test actuator rod 10 is hinged to one end of the shock absorber 11 to be tested, and the other end of the shock absorber 11 to be tested is hinged to the workbench 16. Through the hinged connection between the shock absorber 11 to be tested, the workbench 16 and the test actuator rod 10, the angle rotation of the actuator 1 can be effectively realized during the rotation of the lifting and rotating beam 6, thereby achieving the effect of multi-angle detection test of the shock absorber.

[0045] In addition, in the specific implementation process, both ends of the rotating part 20 are provided with support shaft installation grooves 21, and the fixed part 19 opposite to the rotating part 20 is also provided with the same support shaft installation grooves 21, and the cross beam rotation support shaft 4 is rotatably clamped in the corresponding two support shaft installation grooves 21. Among them, the support shaft installation groove 21 can be provided with a rotating ball or the like that contacts the cross beam rotation support shaft 4, so as to effectively ensure the rotation of the cross beam rotation support shaft 4 in the two support shaft installation grooves 21.

[0046] Of course, in the specific implementation process, the lifting electric cylinder and the thrust cylinder can be connected to the controller, and the operation of the lifting electric cylinder and the thrust cylinder can be controlled by the operation of the controller. The details are not elaborated here.

[0047] In combination with the above embodiments, the rotary lifting multifunctional test bench disclosed in the present application can be assembled with reference to the above structure during operation, and the shock absorber 11 to be tested can be installed at the corresponding position. When multi-angle detection is required, the following embodiments can be adopted for operation: First, the controller can be used to control the lifting electric cylinder 14 to achieve the lifting and lowering of the lifting and rotating beam 6. The lifting and rotating beam 6 is lifted and lowered under the guidance of the guide rod 23. When the lifting and rotating beam 6 rises and falls to the corresponding position, the control of the lifting electric cylinder 14 is stopped, and then the sliding rod can be rotated along the sliding groove 24 of the beam rotating support flange 3 by rotating the beam rotating flange 2. When it rotates to a certain angle, the thrust cylinder 7 can be controlled to extend the beam locking device 5 to lock the rotating part 20 and the fixed part 19, so as to avoid the deflection of the rotating part 20 under vibration during the subsequent test of the shock absorber 11 by the actuator 1, thereby affecting the test effect and test efficiency at the corresponding angle. After the beam locking device 5 locks the lifting and rotating beam 6, the corresponding angle test of the shock absorber 11 to be tested can be achieved by controlling the action of the actuator 1.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
