From the above problems, it can be found that how to actively stop the improper movement path of the user and ensure the safety of the measuring tool, its structure obviously needs to be improved.

In view of the above-mentioned problems and deficiencies in the prior art, the main purpose of the present invention is to provide an anti-collision device for processing and measuring on-line processing machines, which solves the above deficiencies in the prior art through innovative design of the structure.

According to the above object of the present invention, there is provided an anti-collision device for on-line processing and measurement of a processing machine, which is implemented in conjunction with a processing machine running an anti-collision response system, and is used to transmit a sensing voltage output by the anti-collision response system, which includes sequential Connected to a clamp shaft, a lens assembly, an auxiliary light source, and a conductive ring, and also includes at least one first coupling terminal connecting the lens assembly and the clamp shaft to form electrical coupling, at least one connecting the lens assembly and the auxiliary light source A second coupling terminal that forms electrical coupling, at least one third coupling terminal that connects the auxiliary light source and the conductive ring to form electrical coupling, and a plurality of guards respectively provided on the clamping shaft, the lens assembly, and the peripheral side of the auxiliary light source coating. The sensing voltage is transmitted by the above-mentioned components, and during the operation of the processing machine, the anti-collision response system responds to the change of the sensing voltage when the conductive ring is in contact with the workpiece.
