Marking tool for machining

Abstract

The invention discloses a marking tool for machining. The marking tool comprises a pen sleeve, a step hole is formed in the pen sleeve and comprises a small diameter section, a middle diameter section and a large diameter section, a marking pen is contained in the small diameter section, a pen point of the marking pen extends out of the end face of the pen sleeve, the middle diameter section is provided with an elastic rubber mat in contact with the tail end of the marking pen, a steel mat is arranged at the other end of the elastic rubber mat, an internal thread is formed on the large diameter section, and a tightening screw is screwed into the large diameter section to abut against the steel mat. By means of the marking tool for machining, the stretchable amount of the marking pen can be automatically and finely adjusted under a certain pressure, and direct marking machining on a machine tool is achieved after a workpiece surface is machined; and steel mat and elastic rubber mat multi-stage conduction is adopted, so that rigid abrasion is avoided, the aim of stress balance is achieved, and marking is clear, even and accurate.

Description

technical field [0001] The invention belongs to a scribing positioning device, in particular to a scribing tool for mechanical processing. Background technique [0002] In the field of mechanical processing, the processing of parts needs to be completed by multiple processes. In order to ensure the unity of processing standards and the determination of relative positions, in mass production, each process needs to design and manufacture positioning clamping tools to ensure the shape of workpiece processing. bit tolerance requirements. [0003] However, in the development stage of new products, due to the small number of test pieces and the constant changes in structure, the use of tooling in each process is basically one-off, which not only increases the cost of trial production, but also prolongs the development cycle. Therefore, in the process design of the new product development stage, the method of scribing is usually used to connect the previous and subsequent processe...

Problems solved by technology

[0004] However, due to the deviation of the surface quality of the workpiece and the requirement to draw lines on different surfaces, the rigid scribing method is difficult to ensure a clear and uniform processing line, and cannot directly complete the scribing step on the machine tool after the workpiece surface is processed. The clamping process must be arranged, and the scribing process is completed manually

Many processes, low efficiency, and poor marking accuracy
