[0018] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0019] See also Figure 1-3As shown, this embodiment provides a rubber bushing detection device, including a mounting frame 1, a placement frame 2 is fixedly installed on one side of the mounting frame 1, a plurality of placement slots 3 are opened on the top of the placement frame 2, a pair of clamping plates 4 are provided in each of the plurality of placement slots 3, and a connecting plate 1 5 is fixedly installed on opposite sides of the plurality of pairs of clamping plates 4. A slider 6 is slidably installed through one side of the top of the placement frame 2, and two mutually symmetrical connecting plates 2 7 are rotatably installed on the top of the slider 6. The ends of the two connecting plates 2 7 away from the slider 6 are respectively rotatably connected to one side of the two connecting plates 1 5;

[0020] When the slider 6 is moved toward the placement slot 3, the slider 6 will drive the two connecting plates 1 5 away from each other through the two mutually symmetrical connecting plates 2 7, thereby simultaneously increasing the distance between each pair of clamping plates 4. Conversely, the distance between each pair of clamping plates 4 will be reduced.

[0021] A sliding bracket 8 is slidably installed at the top of the placement rack 2 corresponding to the positions of the multiple placement slots 3, and a lifting bracket 9 is slidably installed at the top of the sliding bracket 8. A cylinder for driving the lifting bracket 9 to move up and down in the vertical direction is installed on the sliding bracket 8. Upper clamping plates 10 are rotatably installed at the positions of the multiple placement slots 3 at the bottom of the lifting bracket 9, and lower clamping plates 11 are fixedly installed at the positions of the multiple upper clamping plates 10 on the top of the bottom plate of the sliding bracket 8;

[0022] After the multiple lower clamping plates 11 are moved to the bottom of the placement groove 3 by the sliding bracket 8, when the lifting frame 9 is moved downward, the distance between the multiple upper clamping plates 10 and the multiple lower clamping plates 11 is shortened, and when the lifting frame 9 is moved upward, the distance between the multiple upper clamping plates 10 and the multiple lower clamping plates 11 is increased. When the distance between the upper clamping plates 10 and the lower clamping plates 11 is increased, it is helpful to place the automobile bushing between the upper clamping plates 10 and the lower clamping plates 11. Then, by shortening the distance between the upper clamping plates 10 and the lower clamping plates 11, the rubber layer in the automobile bushing can be clamped in the vertical direction.

[0023] The top of the bottom plate of the mounting frame 1 is slidably mounted with a sliding bracket 2 12, and a plurality of mutually parallel connecting plates 3 13 are rotatably mounted between the sliding bracket 2 12 and the sliding bracket 1 8. A sliding rod 14 is fixedly mounted at the positions of the plurality of placement slots 3 on the top of the sliding bracket 2 12, and a torsion plate 16 is slidably mounted on the outer peripheral wall of the sliding rod 14 through the sliding groove 15. One end of the torsion plate 16 is rotatably connected to one side of the mounting frame 1, and the other end of the torsion plate 16 is provided with a sliding groove 27. The outer peripheral wall of the upper splint 10 is fixedly mounted with a sliding rod 28, and the sliding rod 28 is slidably connected to the sliding groove 27. A rotating rod 19 is rotatably mounted on one side of the mounting frame 1, and a driving motor (not shown in the figure) that drives the rotating plate to rotate is installed on the mounting frame 1. A push-pull rod 20 is rotatably mounted on the end of the rotating rod 19 away from its rotating shaft, and the end of the push-pull rod 20 away from the rotating rod 19 is slidably connected to the mounting frame 1 through the sliding groove 3 21, and the end of the push-pull rod 20 away from the rotating rod 19 is rotatably connected to one side of the sliding bracket 2 12;

[0024] The rotating rotating rod 19 will drive the push-pull rod 20 to slide back and forth in the sliding groove three 21, and finally drive the sliding bracket two 12 to slide back and forth along the bottom of the multiple placement grooves 3 on the mounting frame 1. The reciprocating sliding bracket two 12 will drive the sliding bracket one 8 to reciprocate up and down in the vertical direction through the multiple connecting plates three 13. When the automobile bushing is fixed between the clamping plates 4 and the rubber layer inside it is clamped by the upper plywood 10 and the lower plywood 11, the sliding bracket two 12 that reciprocates up and down will reciprocate and squeeze the clamped rubber layer in the vertical direction through the upper plywood 10 and the lower plywood 11 to perform tensile testing on the rubber layer. In addition, while the sliding bracket two 12 slides back and forth, it will also drive the torsion plate 16 to rotate at a certain speed through the sliding rod one 14. The torsion plate 16 rotates back and forth within a certain rotation angle, and the slide bar 14 will slide in the slide groove 15 to correct the position change between the torsion plate 16 and the slide bar 14 after the rotation. Then the rotating torsion plate 16 will also drive the upper clamping plate 10 to rotate back and forth within a certain rotation angle through the slide bar 2 18, thereby performing a torsion test on the rubber layer in the clamped automobile bushing. At this time, the slide bar 2 18 will slide in the slide groove 2 17 to correct the position change between the torsion plate 16 and the slide bar 2 18 after the rotation, and the slide bar 2 18 can also move in the vertical direction under the restriction of the torsion plate 16 through the slide groove 2 17, thereby correcting the position relationship between the slide bar 2 18 and the torsion plate 16 in the vertical direction when the sliding bracket 8 drives the upper clamping plate 10 to move up and down.

[0025] When the utility model is in use, after the sliding bracket 1 8 drives the multiple lower clamping plates 11 to move to the bottom of the placement groove 3, the multiple automobile bushings are respectively placed on the top of the lower clamping plates 11 in the multiple placement grooves 3, and then the distance between the multiple pairs of clamping plates 4 is reduced, so that the clamping plates 4 fix and clamp the outer peripheral wall of the automobile bushing metal skeleton, and then the lifting frame 9 drives the multiple upper clamping plates 10 to move downward until the multiple upper clamping plates 10 are respectively squeezed on the top of the multiple automobile bushing rubber layers, and then the rotating rod 19 drives the push-pull rod 20 to make the sliding bracket 2 reciprocate along the bottom of the multiple placement grooves 3, so that the sliding bracket 2 12 drives the multiple connecting plates 3 13 The sliding bracket 18 reciprocates in the vertical direction to perform tensile tests on the rubber layers in multiple automobile bushings clamped between multiple upper plywood 10 and lower plywood 11. At the same time, the sliding bracket 2 12 will also drive multiple torsion plates 16 to reciprocate within a certain rotation angle through multiple slide bars 14. The reciprocating torsion plates 16 will drive the upper plywood 10 to reciprocate within a certain rotation angle through the slide bar 2 18, thereby causing the reciprocating upper plywood 10 to perform torsion tests on the rubber layer of the automobile bushing clamped between the upper plywood 10 and the lower plywood 11. Through the above operations, multiple automobile bushings can be subjected to tensile and torsion tests at the same time.
