Description

Technical Field

[0002] With the continuous advancement of technology and the continuous changes in the market, the application of stamping parts in automobile manufacturing has become increasingly extensive and in-depth. In order to ensure the quality of stamping parts, automobile stamping parts need to be quality inspected during processing.

[0003] Ultrasonic thickness gauge is a commonly used equipment in the quality inspection process of automobile stamping parts. Its main function is to accurately measure the thickness of automobile stamping parts to ensure that they meet the production standards. During the inspection, the staff needs to hold the stamping parts steadily with one hand and operate the detection probe with the other hand to measure the thickness. Since stamping parts have different shapes and often have a certain weight, this operation method not only increases the burden on the staff, but also easily leads to inaccurate measurement results due to unstable holding of the stamping parts. Therefore, a quality inspection device for automobile precision stamping parts is proposed. Utility Model Content

[0027] The clamping mechanism 200 includes a gear 201 and a clamping assembly. The gear 201 is rotatably connected to the bottom center of the rotating disk 104. The clamping assembly is provided with two groups, and the two groups of clamping assemblies are symmetrically arranged. The clamping assembly includes a fixed plate 202, a guide rod 203, a sleeve 204, a return spring 205, a rack 206 and a support column 207. The fixed plate 202 is fixedly connected to the bottom of the rotating disk 104. The guide rod 203 is fixedly connected to a side of the fixed plate 202 close to the gear 201. The sleeve 204 is slidably sleeved on the outside of the guide rod 203. The return spring 205 is sleeved on the outside of the guide rod 203 and its two ends are respectively abutted against the fixed plate 202 and the sleeve 204. The rack 206 is fixedly connected to the side wall of the sleeve 204. The support column 207 is fixedly connected to the top of the sleeve 204.

[0028] The abutting posts 207 of the two clamping assemblies respectively pass through the two strip-shaped sliding holes 104 a , and the racks 206 of the two clamping assemblies are respectively disposed on both sides of the gear 201 and mesh with the gear 201 .

In this process, the two sets of return springs 205 are compressed, the stamping parts are placed between the two sets of pillars 207, and then the pillars 207 are released, and the two sets of return springs 205 rebound, so that The two groups of abutment columns 207 clamp the stamping part, and the threaded knob 105 is screwed inwardly so that the threaded knob 105 presses against the turntable 104, and the turntable 104 cannot rotate. The stamping part remains stable, and the thickness of the stamping part can be detected by the probe of the ultrasonic thickness measuring instrument 102. The threaded knob 105 is screwed outwardly so that the threaded knob 105 no longer presses against the turntable 104. At this time, the turntable 104 can rotate. The rubber pad on the top of the turntable 104 is moved by hand to rotate the turntable 104. The turntable 104 drives the stamping part to rotate, so as to adjust the detection position of the stamping part. After adjustment, the threaded knob 105 is tightened to stabilize the stamping part, and then the detection can be carried out.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
