Scribing device

Abstract

The invention relates to a scribing device and belongs to the field of workpiece machining. The scribing device comprises a base, a support located on the base and a scribing penholder. The scribing device is characterized in that the scribing device further comprises a second supporting seat movably connected with the support and a first supporting seat fixedly connected to one side of the second supporting seat, a spring is installed on the second supporting seat, a rotary rod is inserted into the first supporting seat, and the scribing penholder is connected with the first supporting seat through the rotary rod; and a scribing pen refill is installed at the front end of the scribing penholder in an inserted mode, and the rear end of the scribing penholder is supported on the second supporting seat through the spring. The scribing device has the beneficial effects that through double cooperation of the spring and the rotary rod, the scribing pen refill can automatically and vertically move very well according to a machined workpiece, so that the scribing pen refill is the same as the workpiece in contact intensity, and accordingly an even marking line is 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 ...
