The bottom surface of the base 1 is provided with a plurality of universal wheels 33 for moving and fixing the entire device.

Example 2

Referring to FIG. 1 , the difference between the embodiment of the present invention and the embodiment 1 is that a guide key 34 is provided on the bottom end surface of the No. 1 slider 13 , and a guide key 34 is provided on the upper end surface of the No. Guide groove 9, one end of the guide key 34 is arranged in the guide groove 9 and is slidably connected with the inner side wall of the guide groove 9. When the guide key 34 slides on the inner side wall of the guide groove 9, it can effectively improve a The sliding stability of the No. 1 slider 13 on the No. 1 upper end fixing base 3 is determined.

The working principle of the invention is as follows: first, the whole device is moved and placed in a suitable position through a plurality of universal wheels 33, and then the height of the detection equipment 30 is adjusted to a suitable position through a plurality of lifting push rods 31, and then the detection equipment 30 can be adjusted to a suitable position. The metal parts are placed on the fixing fixture 22 for fixing, and then the fixing fixture 22 is placed on the two fixing jaws 23 for clamping and fixing. At this time, the motor 6 can be started to work for the detection operation. The motor 6 drives the screw 12 to rotate and The No. 1 slider 13 and the No. 2 slider 19 drive the entire fixing fixture 22 to slide to the right. When the fixing fixture 22 slides to the right, the detection device can detect one side of the plate in the fixing fixture 22. 13 Move to the right until the gear 14 meshes with the No. 1 rack 10. At this time, the No. 2 fixed shaft 21 will drive the fixing fixture 22 to turn over. When the fixing fixture 22 is turned 180 degrees, just the gear 14 and the No. 1 rack 10 are disengaged , the No. 1 slider 13 continues to move to the right. When the side wall of the guide protrusion 17 is in contact with the side wall of the No. 2 guide plate 8, the inclined side wall of the No. 2 guide plate 8 will exert a certain amount of force on the side wall of the guide protrusion 17. The pressure causes the sleeve 18 to drive the No. 2 fixed shaft 21 to slide downward. When the guide protrusion 17 moves to the rightmost end on the inner wall of the No. 2 guide plate 8, the motor 6 starts to reverse and drives the No. 1 slider 13 to slide to the left. At this time, the detection device will detect the other side of the plate in the fixing fixture 22. When the No. 1 slider 13 continues to move to the left, the gear 14 engages with the No. 2 rack 11, so that the fixing fixture 22 is turned over and when the fixing fixture 22 When turning 180 degrees, the gear 14 is disengaged from the No. 2 rack 11, and at the same time, the No. 1 slider 13 continues to move to the left and when the side wall of the guide protrusion 17 contacts the inner side wall of the No. 1 guide plate 7, the No. 1 guide plate 7 The inclined side wall will exert a certain pressure on the side wall of the guide protrusion 17, so that the sleeve 18 drives the No. 2 fixed shaft 21 to slide upward, so that the fixing fixture 22 returns to the initial position and is ready for the next inspection operation.

The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited to this. should be included within the scope of protection of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
