Scribing device for scribing platform

Abstract

The invention relates to a scribing device for a scribing platform. The scribing device for the scribing platform comprises a fixed block, a moving mechanism and a smearing mechanism, the moving mechanism comprises a moving assembly and a driving assembly, and the smearing mechanism comprises a feeding assembly and a discharging assembly. According to the scribing device for the scribing platform, a lead screw rotates to achieve moving of a moving rod, the moving rod is restored through restoring force of a torsional spring, so that the moving rod better abuts against lantern rings, a telescopic rod between the two lantern rings is always in a tightened state, the lead screw is limited, the accuracy of the moving distance of the moving rod is improved, the scribing precision is improved, and the quality is improved; and a main body is smeared in a positioned manner through the smearing mechanism, dye can slide down along the outer wall of an ejector pin while the ejector pin moves, and therefore fixed-point dyeing of the main body is achieved, the cost is saved, meanwhile, toxic gas generated by dye volatilization is reduced, the working environment of workers is improved, and the use practicability is improved.

Description

technical field [0001] In particular, the invention relates to a scribing device for a scribing platform. Background technique [0002] The existing scribing plate used for the scribing platform for machining has a relatively simple structure. When scribing a workpiece with a smooth surface, it is necessary to smear a dye on the workpiece (the dye is composed of chromosomes and volatile raw materials, such as Gasoline, alcohol, ethanol, etc.), which makes the scribing more clear, but it needs to be applied on a large area when smearing, which is wasteful and has a strong smell, which affects the working environment of the surrounding staff, and the existing scribing plate Generally, the hinge of the two moving rods is realized through the connecting pin, so that the limit of the moving rod is realized by knocking the connecting pin, so that the two moving rods lean against each other, and the limit of the moving angle of the moving rod is realized through friction. In this ...

In this way, in the process of scribing, there will be a slight movement of the moving rod, resulting in a decrease in the accuracy of scribing, which will affect the processing quality of the next process
