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
The invention belongs to the machine-building scoring tool, be specifically related to a kind of center line chalker.
Background technology
In the machine-building process, often need on blank or the surface of the work processed, mark processing line, proof line and centering line with center line as the line benchmark.Line is the foundation of processing, and the lines that marked require size accurate, and svelteness the most important thing is to guarantee that size is accurate.
Pincers worker router commonly used has scriber, scribing block, plan (compasses), centre punch (appearance is dashed), steel ruler, top and platform etc.At present, the process of using pincers worker scoring tool commonly used to carry out the center line line is that workpiece is placed on the platform; Parallel with platform or vertical through adjusting a top plane with workpiece; Measure the length of two parallel surfaces earlier with steel ruler, calculate half the numerical value after, on workpiece, make the mark of central point again with scriber; Or use to plan and find out the mark of central point, two central points are coupled together mark center line then.Its shortcoming has: (1) length consuming time, and operating efficiency is lower; (2) the line precision is low, and the general technology workman precision of ruling is 0.5mm, and advanced techniques workman's line precision is 0.2mm; (3) workman's technical merit influence degree of being rule is big.End for big workpiece and two parallel surfaces is irregular, with the plane that makes marks not when conplane situation, problem is more outstanding.
Summary of the invention
The present invention is used in order to solve existing scoring tool that center line line efficient is low, precision is low, the big problem of the office attendants' technical merit of being rule influence degree, and a kind of center line chalker is provided.
The present invention adopts following technical scheme to realize:
The center line chalker; It is characterized in that comprising support and the reference column and the sliding awl of center line of the both sides that slidably also can lock of support relatively; Two reference columns are parallel in twos with the sliding awl of center line; The sliding awl of center line is positioned on the position of center line of two reference columns, and described reference column is a step axle construction, and the sliding awl of described center line is made up of the cone scriber at jackshaft and two ends.
Principle of the present invention is to be benchmark with two parallel surfaces, under any locus, directly on workpiece, marks center line.
The present invention has following beneficial effect:
1, improves center line line efficient.Efficient improves more than 5 times at least.
2, improve center line line precision.The line precision can reach 0.05-0.1mm.
3, can use the center line of centralized positioning measurement device parallel surface in any position.
4, the center line line precision that causes because of the difference of ruling level of technical solution workman.The line level does not reduce with the reduction of workman's technical merit, and elementary workman can reach senior workman's level.

The specific embodiment
Be described further in conjunction with the accompanying drawing specific embodiments of the invention.
The center line chalker; It is characterized in that comprising support (2) and the reference column (1) and sliding bore (4) of center line of the both sides that slidably also can lock of support (2) relatively; Two reference columns (1) are parallel in twos with the sliding awl of center line (4); The sliding awl of center line (4) is positioned on the position of center line of two reference columns (1), and described reference column (1) is a step axle construction, and the sliding awl of described center line (4) is made up of the cone scriber at jackshaft and two ends.
Reference column is made up of two parallel step axles; The effect of reference column is that the parallel surface along workpiece slides when measuring, and slide mechanism can be guide pillar or guide barrel construction; The part that the reference column diameter is little is used for measuring parallel surface, the cylindrical parallel surface of (convex) common workpiece, and like Fig. 2, shown in Figure 3, the part that diameter is big is used for measuring the parallel surface of (matrix) groove class workpiece, like Fig. 4, shown in Figure 5; Adopt Quenching Treatment, case hardness is high, improves abrasion performance.
It is that two sections is the cone scriber by the jackshaft of the slip of support relatively that center line is drawn awl, and slide mechanism can be guide pillar or guide barrel construction; The effect that center line is drawn awl is on workpiece, to mark center line; Adopt Quenching Treatment, improve abrasion performance.
The effect of support is that to guarantee that reference column, center line are drawn the relative position of awl accurate, satisfies reference column simultaneously, center line is drawn awl and can be slided, and guarantee parallel, to adapt to the requirement of different workpieces; Locking device is installed; Adopt Quenching Treatment, improve abrasion performance.
The effect of locking device is to keep reference column, center line to draw the awl position to satisfy the workpiece requirement, and reference column, center line are drawn awl and do not slided in scratching process.Common structural is: on support, make screw thread, through rotary screw, make reference column, center line draw awl and fix with the support holding position.
Claims (1)
1. center line chalker; It is characterized in that comprising support (2) and the reference column (1) and middle sliding bore (4) of center line of the both sides that slidably also can lock of support (2) relatively; Two reference columns (1) are parallel in twos with the sliding awl of center line (4); The sliding awl of center line (4) is positioned on the position of center line of two reference columns (1), and described reference column (1) is a step axle construction, and the sliding awl of described center line (4) is made up of the cone scriber at jackshaft and two ends.
