2. The utility model discloses a setting up of structure has changed driven experience and has detected the side mode, has eliminated the experience error, has improved the accuracy and the reliability that detect.

Other advantageous effects of the present invention will be further described with reference to the following embodiments.

Drawings

The invention will be further described with reference to the following figures and examples:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view at A;

fig. 3 is an internal detailed view at B.

Detailed Description

As shown in the figure: a resistant material slide finished product detection device, including benchmark board 1, locate 1 upper end opening of benchmark board U type frame 2 down, articulate in eccentric block 3 of U type frame 2 lower part, locate locating plate 4 of 3 lower extremes of eccentric block and be used for connecting eccentric block 3 and locating plate 4's connecting rod 5, the inboard wear-resisting groove in 1 upper portion of benchmark board, 4 single degree of freedom sliding connection of locating plate are in wear-resisting inslot, 1 right side of benchmark board is connected with vertical hole perpendicularly, vertical downthehole single degree of freedom rotates even has

rotation axis

6, 6 lower extremes of rotation axis are equipped with benchmark piece 7, single degree of freedom sliding connection has slide bar 8 in the benchmark piece 7, fixedly connected with micrometer 9 on the slide bar 8.

When the sliding plate is used, the eccentric block 3 is turned upwards, the positioning plate 4 has no positioning effect on the sliding plate at the moment originally, and otherwise, the sliding plate is fixed and positioned. Then the slide bar 8 is pushed manually, the slide bar 8 drives the detection head of the micrometer 9 to move on the slide plate, and then the tolerance is detected. And positioning the defective product when the tolerance is larger than 0.05 mm. In order to effectively detect the slide plate, the rotating shaft 6 can be rotated, but the micrometer 9 rotates by an angle and repeats the above actions. According to the above process, the utility model discloses for the detection of current clearance gauge, it is high to detect the visibility, detects certainly and fast.

In order to prevent the rotating shaft from rotating randomly to influence the reading, the operation is convenient. On the basis of the scheme, the nut 10, the spring 11 and the circular plate 12 with the saw teeth are sequentially connected to the rotating shaft 6 from top to bottom, the circular groove 13 matched with the circular plate 12 is designed on the inner end face of the vertical hole, and the saw tooth groove is formed in the circular groove 13, so that proper damping is introduced, the rotating shaft does not rotate randomly, and then the dial indicator can be accurately stopped at a specific position to facilitate reading. Furthermore, for the convenience of installing the micrometer gauge, the two slide bars 8 are symmetrically arranged, a connecting plate 15 is arranged between the two slide bars 8, a clamping groove is formed in the connecting plate 15, and the micrometer gauge 9 is clamped in the clamping groove. The micrometer 9 is a digital display micrometer or a mechanical micrometer, and is not described herein again for the prior art.

Preferentially: the reference block 7 is provided with a bearing hole, a sliding bearing 14 is connected in the bearing hole, and the sliding bearing 14 is in sliding connection with the sliding rod 8. The sliding bearing 14 is arranged to ensure the motion stability of the sliding rod 8, and simultaneously improve the parallelism of the sliding rod 8 and the reference plate 1, which is beneficial to the accuracy of the detection numerical value.

Preferentially: an operating handle 16 convenient for wrestling the eccentric block 3 is arranged on the eccentric block 3. Since the requirement of the plane quality of the sliding plate is strict and is not suitable for sampling inspection, the frequency of breaking the eccentric block 3 is high when each processed flat plate is inspected, and therefore the handle 16 is designed on the eccentric block 3, so that the operation is convenient and fast, and the working efficiency is further improved.
