[0002] After the damping parts are produced, they usually need to be tested with a torque tester. In the prior art, the use process of the torque tester is as follows: lift the test head of the torque test device with one hand, put the damping part body into the inner wall of the installation sleeve with the other hand, and then put the test head down, connect the outer wall of the damping part and the top convex block through the keyway of the side wall of the installation sleeve and the groove of the lower wall of the test head, drive the installation sleeve and the outer shell of the damping part to rotate through the rotation of the servo motor, the inner core of the damping part is clamped by the test head, and the torque is detected by the test head;

When the damping element is in use, the bumps on the outer shell are all subjected to force, resulting in inconsistency between the detection state and the use state. Therefore, it is necessary to improve the structure of the damping element detection mechanism. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figures 1 to 7 The utility model provides a damping member detection mechanism: including a base 1, a torque testing device, a controller, a servo motor 21 and a damping member body, the servo motor 21 is fixedly connected to the inner lower wall of the base 1, the servo motor 21 extends out of the shaft end fixedly connected with a transmission block 22, the outer wall of the transmission block 22 is slidably connected with a sleeve 8 through a spline and a keyway, the transmission block 22 is transmitted to the sleeve 8 through the spline and the keyway, the inner wall of the sleeve 8 and the position near the upper end thereof is provided with a groove matched with the protrusion on the outer wall of the damping member body, a matching part for transmission is provided between the test head of the torque testing device and the upper wall of the damping member body, and when the servo motor 21 rotates, the damping member body can be driven to rotate through the transmission block 22 and the sleeve 8;

[0030] The sliding sleeve 8 passes through the upper wall of the base 1 and is slidably connected thereto. A first adsorption structure for fixing the horizontal height position of the sliding sleeve 8 by magnetic adsorption is arranged on the inner wall of the sliding sleeve 8 and near the lower wall. The first adsorption structure is a third magnet 23. The third magnet 23 is fixedly connected to the inner wall of the sliding sleeve 8 and is located near the lower end of the sliding sleeve 8. The inner wall of the third magnet 23 is slidably connected to the outer wall of the extended shaft of the servo motor 21. When the upper wall of the third magnet 23 is adsorbed and fixed to the lower wall of the transmission block 22, the upper wall of the sliding sleeve 8 is flush with the upper wall of the damping member body. When the upper wall of the third magnet 23 is adsorbed to the lower wall of the transmission block 22, the sliding sleeve 8 is located at the end of the upper stroke and is fixed to the current position by the third magnet 23. At this time, the outer wall of the damping member body is completely wrapped by the sliding sleeve 8, so that the test state and the use state are kept consistent.

[0031] The damping member body is slidably connected to the inner side wall of one end of the sliding sleeve 8 extending to the upper wall of the base 1. The outer wall of the sliding sleeve 8 and near the upper end are provided with a toggle structure for conveniently driving the sliding sleeve 8 to rise and fall. The toggle structure includes a paddle 9 and a limit block 20. The paddle 9 is fixedly connected to the outer wall of the sliding sleeve 8 and near the upper end. The limit block 20 is fixedly connected between the lower wall of the paddle 9 and the outer wall of the sliding sleeve 8. When the lower wall of the limit block 20 abuts against the upper wall of the base 1, the horizontal height of the upper wall of the sliding sleeve 8 is located at one-fifth of the total height of the damping member body. After the test is completed, the paddle 9 is pressed downward to make the sliding sleeve 8 sink, exposing part of the outer wall of the damping member body, so that the new damping member body can be easily taken out and put in.

[0032] The upper wall of the base 1 is fixedly connected to a column 2 at the rear side of the sliding sleeve 8, the front wall of the column 2 is slidably connected to a sliding plate 4 through a sliding rail 3, the torque testing device is fixedly connected to the front wall of the sliding plate 4 through a mounting plate 6 and is located in the middle position of the sliding plate 4 in the up and down directions, the top of the column 2 is fixedly connected to a top plate 5, the front wall of the sliding plate 4 and near the upper end is fixedly connected to an adsorption box 11, the upper wall of the adsorption box 11 is provided with a groove 17 recessed in the upper wall of the adsorption box 11, the inner wall of the groove 17 is slidably connected to a connecting block 10, and the upper wall of the connecting block 10 is between the opposite side of the top plate 5 and the top wall. A second adsorption structure for adsorbing and fixing the position of the sliding plate 4 is provided, and the second adsorption structure includes a first magnet 7 and a second magnet 12. The first magnet 7 and the second magnet 12 are respectively fixedly connected to the top plate 5 and the side opposite to the connecting block 10. When the damping member body is placed, the torque test device is lifted, and the torque test device will not fall down due to its own weight through the mutual adsorption of the first magnet 7 and the second magnet 12, which is very convenient. When the torque test device needs to be dropped, the first magnet 7 and the second magnet 12 can be separated from the adsorption state by slightly pressing the mounting plate 6;

[0033] An adjustment structure for adjusting the adsorption force of the second adsorption structure is provided between the connecting block 10 and the side wall of the adsorption box 11, and the adjustment structure includes a rotating shaft 13, a rotating wheel 14, a plug rod 15, an eccentric wheel 19, an elliptical hole 18 and a plurality of positioning holes 16. The elliptical hole 18 is arranged on the inner wall of the connecting block 10 in a left-right through-shape, and the eccentric wheel 19 is rollingly connected to the inner wall of the elliptical hole 18. The rotating shaft 13 is eccentrically arranged on the inner wall of the eccentric wheel 19, and the rotating shaft 13 penetrates the eccentric wheel 19 and extends toward the left and right ends. The rotating shaft 13 extends to the left end of the eccentric wheel 19 and penetrates the inner wall of the eccentric wheel 19. The wheel 14 passes through the left wall of the adsorption box 11 and extends to the outside. The wheel 14 is fixedly connected to the left end of the rotating shaft 13. By rotating the wheel 14, the eccentric wheel 19 can be driven to rotate through the rotating shaft 13, and then the connection block 10 is driven to rise or fall in the groove 17 through the cooperation relationship between the eccentric wheel 19 and the elliptical hole 18, so as to adjust the adsorption distance between the second magnet 12 and the first magnet 7 and the adsorption force. It is relatively easy to obtain a position that can keep the torque test device from falling due to its own weight and can easily release the adsorption state, making it more convenient to use.

[0034] A plurality of groups of positioning holes 16 are equally divided into a circle and distributed in sequence on the left wall of the adsorption box 11 with the center of the rotating shaft 13 as the center. The insertion rod 15 is fixedly connected to the side of the rotating wheel 14 facing the adsorption box 11 and is plugged and fixed with any group of the plurality of positioning holes 16. The rotating wheel 14 is pulled out to the left to separate the insertion rod 15 from the positioning hole 16 so that it can be rotated. After being rotated into place, the insertion rod 15 is inserted into the corresponding positioning hole 16 to fix the position.

[0035] Working principle: the transmission block 22 is transmitted through the spline, keyway and sleeve 8. A groove that cooperates with the protrusion on the outer wall of the damping element body is arranged on the inner wall of the sleeve 8 and near the upper end. A matching part for transmission is arranged between the test head of the torque testing device and the upper wall of the damping element body. When the servo motor 21 rotates, the damping element body can be driven to rotate through the transmission block 22 and the sleeve 8. When the upper wall of the third magnet 23 and the lower wall of the transmission block 22 are adsorbed, the sleeve 8 is located at the end of the upper stroke and is fixed to the current position by the third magnet 23. At this time, the outer wall of the damping element body is completely wrapped by the sleeve 8, so as to achieve the purpose of keeping the test state consistent with the use state. After the test is completed, press the paddle 9 downward to make the sleeve 8 sink and expose part of the outer wall of the damping element body, so that the new damping element body can be easily taken out and placed. When placing the damping element body, lift the torque testing device and pass the first magnet 7. The mutual adsorption of the second magnet 12 prevents the torque test device from falling due to its own weight, which is very convenient. When the torque test device needs to be dropped, the mounting plate 6 can be slightly pressed to break away from the adsorption state of the first magnet 7 and the second magnet 12. By rotating the rotating wheel 14, the eccentric wheel 19 can be driven to rotate through the rotating shaft 13, and then the connecting block 10 can be driven to rise or fall in the groove 17 through the matching relationship between the eccentric wheel 19 and the elliptical hole 18, so as to adjust the adsorption distance between the second magnet 12 and the first magnet 7 and the adsorption force. It is relatively easy to obtain a position that can keep the torque test device from falling due to its own weight and can easily release the adsorption state, making it more convenient to use. Pulling out the rotating wheel 14 to the left separates the insertion rod 15 from the positioning hole 16, so that it can be rotated. After rotating into place, the insertion rod 15 is inserted into the corresponding positioning hole 16 to fix the position.
