[0026] See also Figures 1 to 4 The utility model provides a penetration detection device, including a base 100, a microscopic detection device 200, a support plate 300, a support rod 400 and a fixing mechanism 500.

[0027] Specifically, the support plate 300 is disposed on the base 100. The top surface of the support plate 300 is provided with a plurality of through holes communicating with the inner cavity thereof at intervals, and there are a plurality of support rods 400, and the plurality of support rods 400 are inserted into the corresponding through holes one by one and can slide up and down. The fixing mechanism 500 is disposed in the support plate 300 and connected to all the support rods 400 to fix all the support rods 400.

[0028] When in use, after the workpiece to be inspected is cut into the required shape and then ground and polished, the workpiece is placed on the support rod 400 when the support rod 400 is in a natural state, and the surface to be inspected of the workpiece is aligned with the lens of the microscopic inspection device 200. Then, after the workpiece is pressed down to the required position, the fixing mechanism 500 is started to fix all the support rods 400, so that the workpiece can be stably supported and then tested by the microscopic inspection device 200.

[0029] The above-mentioned penetration detection device can conveniently provide fast and stable support for workpieces of any shape, thereby reducing production costs and improving detection efficiency.

[0030] In this embodiment, the support rod 400 includes a first elastic member 410 and a support rod 420. The support rod 420 is supported in the through hole by the first elastic member 410, and the fixing mechanism 500 can be tightly clamped on the support rod 420. When the workpiece is placed on the support rod 420, the workpiece is pressed down to the target position with the detection surface facing upward, and then the fixing mechanism 500 is activated to clamp and fix the support rod 420, so that a stable support can be formed for the workpiece.

[0031] In this embodiment, the fixing mechanism 500 includes an air tube 510 and multiple airbag rings 520. An air storage cavity 310 is opened at the top of the support plate 300. All the through holes extend downward through the air storage cavity 310. The support rod 420 passes through the air storage cavity 310. Multiple airbag rings 520 are located in the air storage cavity 310 and are arranged one by one corresponding to the through holes. The two ends of the airbag ring 520 are respectively sealed and connected to the top and bottom of the air storage cavity 310.

When it needs to be held tightly and fixed, the air pipe 510 is connected to the inflation device, and then the air storage chamber 310 is inflated. The gas drives the airbag ring 520 to hold the support rod 420 tightly, and then the detection can be carried out. After the detection is completed, the gas in the air storage chamber 310 can be discharged.
