Scribing device

Abstract

The invention discloses a scribing device which comprises a base, a first support frame and a second support frame, wherein the first support frame and the second support frame are fixedly arranged on the upper end face of the base; support tables for supporting scribed workpieces are respectively arranged at the upper ends of the first support frame and the second support frame; a sliding block which can slide on the upper end face of the base is arranged on the upper end face of the base; an upright post is fixedly arranged on the sliding block; a scribing fixed rod is fixedly arranged at the upper end of the upright post; a scribing needle which is fixedly arranged at one end of the scribing fixed rod is arranged at the upper end of the upright post; and a staff gauge is arranged on the base at one side of the sliding block. Workpieces are placed on the support tables at the upper ends of the first support frame and the second support frame, so that one end of each workpiece is aligned to a needle head of the scribing needle; the sliding block is moved within a stroke of a guide rail according to the required scribing length; the staff gauge can be used for accurately measuring the stroke of the scribing block; after accurate positioning, the scribing needle is pressed to scribe on the workpieces and further the workpieces can be accurately scribed. Therefore, the scribing device disclosed by the invention has the advantages of ensured scribing precision, short scribing time and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a scribing device. Background technique [0002] When cutting a workpiece with a long length, it is first necessary to scribe the workpiece to be cut. The existing scribing method is still the original method, that is, use a tape measure to measure from one end of the workpiece, and when the required length is measured, , then draw the line at this place, such a marking method cannot guarantee the accuracy of the marking, and will produce a large dimensional error, so it is necessary to repeatedly mark the workpiece to ensure its accuracy. The defects of long scribing time, low efficiency and poor accuracy are caused. Contents of the invention [0003] In view of the above technical problems, the present invention provides a scribing device, which can ensure the accuracy of scribing, with short scribing time and high efficiency. [0004] Realize the ...
