However, the existing inspection is often carried out by manual visual inspection, which is prone to errors and omissions, so this case is proposed. Utility Model Content

[0006] Preferably, a magnetic end block is fixedly provided at intervals on the left end of the dust-free bin for magnetically adsorbing on the inner wall surface of the clamping block, so as to ensure that one side of the dust-free bin is flush with one of the clamping blocks.
[0007] Preferably, a rechargeable lithium battery is embedded and fixed in the platform to power the multi-channel laser rangefinder inside the dust-free bin and the PLC microcontroller.
[0008] Preferably, a switch button for controlling the on and off of the multi-channel laser rangefinder is fixedly provided on the upper end surface of the dust-free bin.
[0009] Preferably, a return spring is sleeved on the outside of the insert tube, and the two ends of the return spring respectively abut against the ends of the rubber end block and the insert tube seat, thereby ensuring that the end of the rubber end block can maintain good contact with the clamping block during the clamping process of the bench vise.

[0011] The advantages and positive effects of the utility model are: the platform is pulled apart relative to the floating platform so that the dust-free bin is at the same height as the clamping blocks, and then the magnetic end block is magnetically attracted to the inner wall of one of the clamping blocks, and then the bench vise is used to clamp the insert so that the insert is contracted inwards. During this process, the PLC single chip is used to detect whether the two clamping blocks are parallel. The utility model is simple and efficient, and the detection result is accurate.
