For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] The specific embodiments are as follows:
[0029] Embodiment 1, as Figure 1-8 As shown, a shock absorber tension and compression multi-angle test device comprises a support base 1, a connecting member 12, a lifting assembly, a force-applying assembly and a clamping member 10. A connecting member 12 is provided at one end of the support base 1 for connecting the shock absorber 11, and the other end of the shock absorber 11 is connected to a tensile test machine.
[0030] The end of the support base 1 away from the connecting member 12 is connected to the lifting assembly. The lifting assembly includes a guide rail 2, a guide block 3 and a locking assembly. The guide rail 2 is connected to the support base 1, and the guide block 3 is slidably connected to the guide rail 2. The guide block 3 is locked on the guide rail 2 by the locking assembly to adjust the height of the guide block 3.
[0031] In this embodiment, the combination of the guide rail 2 and the guide block 3 adopts a linear guide rail, which can bear a certain torque and realize high-precision linear motion under high load conditions. Two groups or more linear guide rails are provided.
[0032] In this embodiment, the force-applying component adopts an electric cylinder 5, which can move continuously, with low to high loads, and has extremely high positioning accuracy and controllability. The electric cylinder 5 moves synchronously with the guide block 3, which is convenient for adjusting the height of the electric cylinder 5. The movable end of the electric cylinder 5 is connected to the clamping member 10, which is used to clamp on the shock absorber 11, and the electric cylinder 5 drives the shock absorber 11 to apply lateral force.
[0033] When the shock absorber tension and compression multi-angle test device of this embodiment is in use, the support seat 1 is connected to the workbench of the tension tester, the lower end of the shock absorber 11 is connected to the connecting piece 12, and the upper end is connected to the tension tester. The electric cylinder 5 is driven to extend, and the clamping piece 10 is connected to the shock absorber 11. Through the extension or contraction of the electric cylinder 5, a lateral thrust or tension is applied to the shock absorber 11 to complete the durability test of the shock absorber 11. Due to the setting of the lifting component, it is possible to apply force to different positions on the shock absorber 11, and the test is more comprehensive and reliable.
[0034] Furthermore, the lifting assembly further includes a sliding connecting plate 4. In this embodiment, four groups of guide rails 2 and guide blocks 3 of the lifting assembly are provided. The sliding connecting plate 4 is simultaneously connected to the four groups of guide blocks 3, and the electric cylinder 5 is fixedly connected to the middle part of the sliding connecting plate 4. The movable end of the electric cylinder 5 passes through the sliding connecting plate 4 and extends to one side of the shock absorber 11. In this way, it is not only convenient to install the electric cylinder 5, but also ensures the balance of the support of the sliding connecting plate 4.
[0035] Furthermore, the locking assembly includes a clamping lower block 6, a clamping upper block 7, and a bolt 8. The clamping lower block 6 is arranged on the side of the guide rail 2 away from the shock absorber 11, the clamping upper block 7 is arranged on the side of the guide rail 2 close to the shock absorber 11, and the clamping lower block 6 is fixedly connected to the sliding connecting plate 4. The clamping lower block 6 and the clamping upper block 7 are connected by the bolt 8 to clamp the guide rail 2 to achieve the locking state of the locking assembly.
[0036] Furthermore, an elastic member 9 is provided between the lower pressing block 6 and the upper pressing block 7. When the height of the electric cylinder 5 needs to be adjusted, the elastic member 9 is used to separate the lower pressing block 6 and the upper pressing block 7 by the rebound force after the bolt 8 is loosened, and the height of the electric cylinder 5 can be adjusted by the sliding guide block 3, which is convenient to adjust and can be locked repeatedly.
[0037] In this embodiment, the elastic member is compressed and elastic, and when subjected to an external load, the spring contracts and deforms to store deformation energy.
[0038] Furthermore, the clamping member 10 includes a first clamping plate a101 and a second clamping plate a102. The first clamping plate a101 and the second clamping plate a102 are both in the shape of bent plates. The first clamping plate a101 and the second clamping plate a102 are arranged relative to the car and connected to the movable end of the electric cylinder 5 at one intersection, and a detachable connection is used at another intersection to facilitate the connection between the clamping member 10 and the shock absorber 11.
[0039] In other embodiments, the clamping member 10 includes a first clamping plate b103, a second clamping plate b104 and a third clamping plate b105. The first clamping plate b103 is in the shape of a bent plate, and the second clamping plate b104 and the third clamping plate b105 have the same structure and are straight. The second clamping plate b104 and the third clamping plate b105 are respectively rotatably connected to the two bent portions on the first clamping plate b103, and the ends of the second clamping plate b104 and the third clamping plate b105 are detachably connected to facilitate disassembly and assembly with the shock absorber 11. The other structures are the same as those in the above embodiments and are not repeated here.
[0040] In other embodiments, the clamping member 10 includes a first clamping plate c106 and a second clamping plate c107. Both the first clamping plate c106 and the second clamping plate c107 are straight, and two of each are provided. The two first clamping plates c106 are cross-arranged and connected at the active end of the electric cylinder 5 at the intersection. The two second clamping plates c107 are cross-connected. The end of the second clamping plate c107 and the corresponding end of the first clamping plate c106 are detachably connected to facilitate disassembly and assembly with the shock absorber 11. Other structures are the same as those in the aforementioned embodiments and are not repeated here.
[0041] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
