[0002] In order to detect the vibration reduction effect of the spring shock absorber, determine the natural frequency of the spring shock absorber, and improve the stability of the equipment so that the equipment can adapt to different working conditions, after the spring shock absorber is produced and processed, it is necessary to use a test fixture to test its vibration performance, and the spring shock absorber can be clamped and positioned through the internal fixture of the fixture. However, when clamping the spring shock absorber, the existing test fixture mostly uses the effect of positioning its two ends, but cannot adjust the inclination of the spring shock absorber. This obviously limits the simulation of the actual use environment and the evaluation of the shock absorber performance, and thus cannot meet the specific application requirements, which has major defects. For this reason, we proposed a vibration test fixture. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 The utility model provides a technical solution: a vibration test fixture, including a test platform 1 and an arc-shaped movable plate 12, a first connecting seat 11 is fixedly installed on the upper end of the test platform 1, the arc-shaped movable plate 12 is slidably installed in the first connecting seat 11, and an adjusting gear 43 that fits with the outer periphery of the arc-shaped movable plate 12 is rotatably installed in the first connecting seat 11, second connecting seats 13 are fixedly installed on both sides of the upper end of the arc-shaped movable plate 12, a movable rod 14 is plugged into the second connecting seat 13, and a limit plate 2 is fixedly installed on the inner end of the movable rod 14, and a rotating ring 25 is rotatably installed on the inner end of the limit plate 2, and a plurality of positioning blocks 21 that fit with each other are slidably installed between the limit plate 2 and the rotating ring 25, and an insertion cavity 27 is opened in the middle of the rotating ring 25.

[0023] Working principle: When installing the spring shock absorber, place the spring shock absorber between the two limit plates 2. In the second connecting seat 13, adjust the limit plates 2 so that both ends of the spring shock absorber contact the limit plates 2 on both sides. Rotate the rotating ring 25. Through the sliding connection between the positioning blocks 21 and the limit plates 2 and the rotating ring 25, each positioning block 21 can be driven to retract inward, thereby achieving the effect of clamping and positioning the two ends of the spring shock absorber.

[0024] When the inclination of the spring shock absorber needs to be adjusted, the arc-shaped movable plate 12 is slid in the first connecting seat 11. Since the arc-shaped movable plate 12 is arranged in an arc shape, the inclination of the spring shock absorber can be adjusted.

[0025] As a further description of the above technical solution: each positioning block 21 is fixedly installed with a first limit slider 22 and a second limit slider 24 on the inner and outer sides respectively, the inner wall of the limit plate 2 is provided with a first limit slide 23 which is slidably connected to the first limit slider 22, the inner wall of the rotating ring 25 is provided with a second limit slide 26 which is slidably connected to the second limit slider 24, the outer end of the second connecting seat 13 is fixedly installed with a limit seat 3, the movable rod 14 is arranged in the limit seat 3, the inner wall of the limit seat 3 is provided with a limit plug 32, the outer periphery of the movable rod 14 is provided with a limit slot 33 which is plugged into the limit plug 32, the outer periphery of the movable rod 14 is provided with a threaded curved groove 34, and the outer end of the limit seat 3 is rotatably installed with a threaded ring 35 which is threadedly connected to the threaded curved groove 34.

[0026] Specifically, the sliding connection between the first limiting slider 22 and the first limiting slot 23 can limit the movement direction of each positioning block 21 in the limiting plate 2, so that the rotating ring 25 can drive each positioning block 21 to retract inward or expand outward through the sliding connection between the second limiting slider 24 and the second limiting slot 26, so that the positioning block 21 can clamp and position the two outer ends of the spring shock absorber;

[0027] When it is necessary to adjust the distance between the limit plates 2 on both sides, the threaded ring 35 is rotated at the outer end of the limit seat 3. The limit seat 3 limits the movement direction of the movable rod 14 through the sliding connection between the limit plug 32 and the limit slot 33, so that the rotating threaded ring 35 can drive the movable rod 14 to move through the threaded connection between it and the threaded curved groove 34, thereby adjusting the distance between the limit plates 2 on both sides.

[0028] As a further description of the above technical solution: an arc-shaped slot 4 is provided at the upper end of the first connecting seat 11, and arc-shaped limit slide grooves 41 are provided on both sides of the inner cavity of the arc-shaped slot 4, and arc-shaped limit sliders 42 that are slidably connected to the arc-shaped limit slide grooves 41 are fixedly installed on both sides of the arc movable plate 12; limited rotation grooves 432 are provided on both sides of the adjusting gear 43, and limited rotation seats 431 that are rotatably connected to the limited rotation grooves 432 are fixedly installed on both sides of the inner cavity of the first connecting seat 11; a first positioning tooth groove 441 and a second positioning tooth groove 442 are respectively provided in the middle of the limited rotation seat 431 and the adjusting gear 43, and a positioning gear block 44 is inserted and installed in the first positioning tooth groove 441 and the second positioning tooth groove 442, and a threaded hole 453 is provided in the middle of the positioning gear block 44, and limited rotation holes 451 are provided on both sides of the inner cavity of the first connecting seat 11, and a threaded rod 45 threadedly connected to the threaded hole 453 is rotatably installed between the two limited rotation holes 451.

[0029] Specifically, when the inclination of the spring shock absorber needs to be adjusted, the arc-shaped limit slide groove 41 and the arc-shaped limit slider 42 are slidably connected to each other, so that the arc-shaped movable plate 12 can be slid on the upper end of the first connecting seat 11, thereby mechanically adjusting the inclination of the two second connecting seats 13, thereby achieving the effect of adjusting the inclination of the spring shock absorber;

[0030] The arc movable plate 12 sliding in the arc slot 4 can drive the adjusting gear 43 to rotate in the first connecting seat 11 through the meshing connection between it and the adjusting gear 43. When the arc movable plate 12 needs to be positioned, the threaded rod 45 can be rotated in the limited rotation hole 451. The first positioning tooth groove 441 is connected with the positioning tooth block 44 through the plug-in connection between it and the positioning tooth block 44. Under the restriction of the movement direction of the positioning tooth block 44, the rotating threaded rod 45 can drive the positioning tooth block 44 to move through the threaded connection between it and the threaded hole 453, so that the positioning tooth block 44 is plugged into the first positioning tooth groove 441 and the second positioning tooth groove 442 at the same time, so as to position the adjusting gear 43 in the first connecting seat 11, thereby achieving the effect of positioning the arc movable plate 12 and avoiding the deviation of the tilted spring shock absorber.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
