Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber dynamometers, in particular to a positioning and clamping mechanism for a shock absorber dynamometer. Background Art

[0002] Shock absorbers are often used to reduce the shock of car seats. In order to reduce the bumps of the seats during driving, shock-absorbing springs are installed under the seats. When passing through uneven roads, the shock-absorbing springs can filter the vibrations caused by the bumps of the car. However, the shock-absorbing springs themselves will also have reciprocating motion, and the shock absorbers are used to suppress the movement of the shock-absorbing springs. The shock absorber dynamometer is used to perform dynamometer characteristics and durability fatigue tests on the shock absorber. In the existing shock absorber dynamometer, the bottom of the bottom cylinder is first fixed to the positioning seat, and then the front fork tube is manually pulled up. The top of the front fork tube contacts the bottom of the plug, and the bottom cylinder may tilt, resulting in inaccurate test data in the later stage. For this reason, we propose a positioning clamping mechanism for the shock absorber dynamometer. Utility Model Content

DETAILED DESCRIPTION

[0016] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0017] like Figure 1-3When the two support plates 3 are in contact with each other, the two support plates 3 are in contact with each other, and the two support plates 3 are in contact with each other, so that the two support plates 3 can be fixedly connected to each other through a top plate 3. A hydraulic cylinder 4 is arranged in the middle of the top plate 3. The stroke end of the hydraulic cylinder 4 passes through the top plate 3 and is fixedly connected to the push seat 5. When the hydraulic cylinder 4 is working, the hydraulic cylinder 4 can push the push seat 5 to move in the vertical direction. Threaded rods 6 are inserted at both sides of the lower end of the push seat 5. One end of the threaded rod 6 is located in the push seat 5 and is movably connected to the first clamping plate 7. The threaded rod 6 is fixedly connected to the rotating disk 8 on the side away from the first clamping plate 7. The threaded rod 6 is threadedly connected to the push seat 5. When the rotating disk 8 is rotated, the rotating disk 8 drives the threaded rod 6 to rotate. When the threaded rod 6 rotates, the threaded rod 6 can push the first clamping plate 7 to move in the horizontal direction. The purpose of positioning the upper end of the shock absorber can be achieved through the mutual cooperation between the two first clamping plates 7. A test seat 9 is provided in the middle of the upper part of the base plate 1, and four first guide sleeves 10 are provided on the support rod 2. The first guide sleeve 10 is movably connected to the support rod 2. A fixing plate 11 is provided on the side of the first guide sleeve 10 close to the base plate 1. The two fixing plates 11 located in the same horizontal plane are fixedly connected by a guide rod 12. Second guide sleeves 13 are provided at both ends of the guide rod 12. The second guide sleeve 13 is movably connected to the guide rod 12. A connecting plate 14 is provided on the side close to each other of the second guide sleeves 13. A second clamping plate 15 is provided between the two connecting plates 14 located on the same side of the second guide sleeve 13. The second guide sleeve 13 can move horizontally on the guide rod 12. By adjusting the position of the second guide sleeve 13, the spacing between the two second clamping plates 15 is also changed. Therefore, the purpose of positioning the lower end of the shock absorber can be achieved through the mutual cooperation between the two second clamping plates 15.

[0021] The four corners of the base plate 1 are provided with mounting holes 19 , through which the clamping mechanism can be fixedly installed.

[0022] The first clamping plate 7 and the second clamping plate 15 are both arc-shaped plates, and the arc-shaped plates match the cross-section of the shock absorber, thereby effectively improving the stability of the first clamping plate 7 and the second clamping plate 15 in clamping the shock absorber.

[0023] When the hydraulic cylinder 4 is working, the hydraulic cylinder 4 can push the push seat 5 to move in the vertical direction.

The second guide sleeve 13 can move in the horizontal direction on the guide rod 12. By adjusting the position of the second guide sleeve 13, the spacing between the two second clamping plates 15 is also changed. Therefore, through the mutual cooperation between the two second clamping plates 15, the purpose of positioning the lower end of the shock absorber can be achieved. The first guide sleeve 10 can move in the vertical direction on the support rod 2, so that the second clamping plate 15 can clamp different positions of the shock absorber.
