a marking device

Abstract

The invention relates to a marking device and belongs to the field of workpiece machining The marking device comprises a base, a support placed on the base and a marking penholder and is characterized by further comprising a second supporting seat movably connected with the support and a first supporting seat fixedly connected with one side of the second supporting seat; a spring is arranged on the second supporting seat; a rotary rod is inserted in the first supporting seat; the marking penholder is connected with the first supporting seat through the rotary rod; a pen core is inserted at the front end of the marking penholder and the rear end of the marking penholder is supported on the second supporting seat through the spring. The marking device has the advantages that according to dual match of the spring and the rotary rod, the marking pen core is capable of automatically moving vertically according to a machined workpiece so that contacting force of the marking pen core and the workpiece is equal and an even marking line can be drawn.

Description

technical field [0001] The invention relates to a scribing device, which belongs to the field of workpiece processing. Background technique [0002] In factory machining, it is very important to draw the basic line. Usually it is easier to draw the line on the plane or on the outer circle of the cylinder, but sometimes it is necessary to draw the line on the workpiece with an irregular outer contour, such as in the six When scribing lines on multi-prisms such as prisms and octagonal prisms, because the distance between the scribing track on different surfaces on the contour and the rotation center of the workpiece varies, not only is it difficult to scribble, but it is also difficult to ensure that the lines can be drawn on the same plane, and the scribing is not standardized. Not allowed, this will affect the quality of the processed workpiece, resulting in waste of raw materials. Contents of the invention [0003] The present invention provides a scribing device aiming ...
