Embodiment Construction

[0019] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0020] The central line marking device is characterized in that it includes a bracket (2), and positioning columns (1) and centerline sliding cones (4) on both sides that can slide and lock relative to the bracket (2), and two positioning columns ( 1) Parallel to the centerline sliding cones (4) two by two, the centerline sliding cones (4) are located on the centerline positions of the two positioning columns (1), the positioning columns (1) are stepped shaft structures, the described The center line sliding cone (4) is made up of the cone scribing pins at the middle shaft and two ends.

[0021] The positioning column is composed of two parallel step shafts; the function of the positioning column is to slide along the parallel surface of the workpiece during measurement. The sliding mechanism can be a guide column or a guide groove structure; type...

Abstract

The invention belongs to a marking tool for machinofacture, and particularly relates to a centre line marking device, which solves the problems of low efficiency and accuracy and high influence degree by the technical level of marking workers in the conventional marking tool for marking centre lines. The centre line marking device comprises a support, and positioning columns and centre line sliding cones which can slide and can be locked tightly on both sides relative to the support, wherein the two positioning columns and the two centre line sliding cones are parallel to each other; the centre line sliding cones are positioned at the centre line positions of the two positioning columns; each positioning column has a structure of a step shaft; and the centre line sliding cones consist of middle shafts and cone scribers at both ends. The centre line marking device has the advantages that the centre line marking efficiency and accuracy are improved, and a center positioning device can be used at any positions to measure centre lines of parallel surfaces.

Description

technical field [0001] The invention belongs to mechanical manufacturing scribing tools, in particular to a central line scribing device. Background technique [0002] In the process of mechanical manufacturing, it is often necessary to use the center line as the marking reference to draw the processing line, proof line and alignment line on the surface of the blank or the processed workpiece. Scribing is the basis for processing. The drawn lines require accurate dimensions, clear lines, and the most important thing is to ensure accurate dimensions. [0003] Commonly used fitter scribing tools include scribing needles, scribing disks, planning gauges (compasses), center punches (sample punches), steel rulers, tops, and platforms. At present, the process of using the common fitter marking tool to mark the center line is to place the workpiece on the platform, adjust a plane of the workpiece to be parallel or perpendicular to the platform by adjusting the top, and measure the...
