When the spindle of the processing machine is replaced with a measuring tool, the design of the spindle's travel route needs to maintain a preset distance from the workpiece, which deviates from the working form of the tool.

Also because it is different from the usual work, it often happens that the user does not operate properly for some reason, or subconsciously regards the measuring tool as a processing tool. A collision is formed, causing damage to the measuring tool.

From the above problems, it can be found that how to actively stop the user's improper operation path 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 on-line processing measurement anti-collision device for processing machines, which solves the above-mentioned deficiencies in the prior art through innovative structural design.

According to the above object of the present invention, an on-line processing measurement anti-collision device for a processing machine is provided, 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 serial connected to a clamp shaft, a lens assembly, an auxiliary light source, and a conductive ring, and at least one first coupling terminal connecting the lens assembly and the clamp shaft to form an electrical coupling, at least one connection lens assembly and the auxiliary light source A second coupling terminal forming an electrical coupling, at least one third coupling terminal connecting the auxiliary light source and the conductive ring to form an electrical coupling, and a plurality of guards respectively provided on the clamp shaft, the lens assembly, and the outer peripheral side of the auxiliary light source coating. The sensing voltage is transmitted through the above components, and during the operation of the processing machine, the anti-collision response system responds to the sensing voltage change when the conductive ring is in contact with the workpiece.
