DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment: As Figures 1-4 shown, an automobile checking fixture sliding mechanism includes a checking fixture table 1, a movable clamping block 2, and a mounting seat 3. Three fixed clamping blocks 101 are fixedly installed on the top of the checking fixture table 1 through bolts. One end of the movable clamping block 2 is rotatably installed with a sliding rod 202. A rotating handwheel 203 is fixedly installed at the end of the sliding rod 202 away from the movable clamping block 2. A limiting rod 204 and a limiting piece 205 are fixedly installed on the sliding rod 202. Multiple convex columns 206 are annularly fixedly installed at one end of the limiting piece 205. The mounting seat 3 is fixedly installed on the checking fixture table 1 through a fixing bolt. A limiting cylinder 301 is provided at one end of the mounting seat 3. A limiting groove 302 is opened on the limiting cylinder 301. Multiple guiding blocks 304 are annularly provided at the end of the mounting seat 3 away from the movable clamping block 2. The sliding rod 202 is movably inserted into the circular parts of the mounting seat 3 and the limiting cylinder 301.

[0022] A sliding groove 102 is opened on the top of the checking fixture table 1. A sliding block 201 is fixedly installed at the bottom of the movable clamping block 2 and is slidably installed in the sliding groove 102 on the checking fixture table 1 through the sliding block 201. During use, the sliding of the sliding block 201 and the sliding groove 102 plays a role in guiding and positioning the movement of the movable clamping block 2.

[0023] A ball head 207 is rotatably installed at the end of the convex column 206 away from the limiting piece 205. During use, the rotation of the ball head 207 is used to reduce the resistance of the sliding rod 202 to rotate.

[0024] The width of the limiting groove 302 is equal to the diameter of the limiting rod 204 and the limiting groove 302 is arranged in an "L" shape. The number of guiding blocks 304 is the same as the number of convex columns 206 and their positions correspond. The cross-section of the guiding block 304 is a right triangle. During use, the sliding rod 202 is pushed to drive the limiting piece 205 to move and make the convex column 206 contact the guiding block 304, and the sliding rod 202 is rotated through the guiding of the guiding block 304. The limiting rod 204 is driven to rotate by the rotation of the sliding rod 202 so that the limiting rod 204 is stuck in the limiting groove 302.

[0025] Spring sleeves are provided at the ends of the mounting seat 3 and the limiting piece 205 close to each other, and a return spring 303 is clamped between the two spring sleeves. During use, if it is necessary to release the clamping of the automobile part to be inspected, the sliding rod 202 is rotated, and the elastic action of the return spring 303 can be used to return automatically.

[0026] Specifically, when the utility model is in use, the automotive part to be tested is placed in the fixed clamping block 101. By rotating the handle, the sliding rod 202 is pushed to move. The movement of the sliding rod 202 drives the movable clamping block 2 to move until it cooperates with the fixed clamping block 101 to achieve the purpose of clamping. During the movement of the sliding rod 202, the limiting piece 205 is driven to move and the convex column 206 contacts the guiding block 304, and the sliding rod 202 is guided by the guiding block 304 to rotate (the ball head 207 can reduce the resistance of the sliding rod 202 to rotate). The rotation of the sliding rod 202 drives the limiting rod 204 to rotate so that the limiting rod 204 is stuck in the limiting groove 302. If it is necessary to replace the next automotive part to be inspected, only need to rotate the sliding rod 202 by rotating the handle, and the limiting piece 205 can be reset by the elastic action of the return spring 303.
