[0002] In current industrial production, punches are being used more and more widely, and the precision requirements for stamped products are becoming more and more precise. In order to achieve high-precision and high-quality stamped products, the precision requirements for punch structures are even higher. The depth of the punch groove is measured by using a depth measuring head of a vernier caliper or a modified dial indicator.

[0003] When using a groove depth measuring instrument to measure the groove depth, the height and spatial position of the groove depth measuring instrument need to be adjusted to achieve better detection. However, existing groove depth measuring instruments require adjustment of the clamping frame or the height of the dial indicator probe during use. If the dial indicator probe is adjusted significantly over a long period of time, it will result in inaccurate accuracy. At the same time, manually adjusting the part being tested on the testing table may cause accidental touches.

[0004] Based on this, the present invention designs a punch groove depth detector to solve the above problems. Utility Model Content

A rack 10 is installed on the outer wall of the support frame 8. A lifting device 201 is sleeved on the outer wall of the support frame 8. The lifting device 201 includes a lifting frame 11 and a lifting handle 15. A gear 12 is sleeved inside the rear cavity of the lifting frame 11. The gear 12 and the rack 10 mesh with each other. The lifting handle 15 passes through the gear 12 and is installed on the inner wall of the lifting frame 11. The gear 12 and the lifting handle 15 are rotatable relative to the lifting frame 11.

[0028] As attached Figure 3 and attached Figure 7 As shown, a limiting support 13 is installed on the top of the lifting frame 11.

[0029] As attached Figure 4 As shown, the bottom of the support frame 8 is provided with an irregular groove 28 and a screw hole, and the top outer wall of the support frame 8 is provided with a rectangular groove 9, and a rack 10 is fixedly installed inside the rectangular groove 9.

[0030] One specific application of this embodiment is as follows: This utility model achieves self-locking adjustment of the horizontal height of the digital depth detector 101 through the meshing of the gear 12 and rack 10 inside the lifting device 201 and the cooperation of the limiting plate 14. When it is necessary to rise, the lifting handle 15 is twisted by pressing one end of the limiting plate 14, so that the digital depth detector 101 and the clamping frame 301 can rise horizontally. This effectively reduces the adverse factors caused by touching the digital depth detector 101 or adjusting the clamping frame 301 when adjusting the height of the detector during groove depth detection. At the same time, the self-locking function of the lifting device 201 also has a secondary restriction and protection effect on the clamping frame 301 and the detection instrument. In addition, when the lifting device 201 detects the groove depth of the punch, the height of the detection tool can be easily adjusted, reducing the time consumed during detection and effectively increasing the efficiency of groove depth detection.
