Abstract
The utility model belongs to a mechanical manufacturing scribing tool, especially relates to a central line scribing device, which solves the problems that the existing scribing tool has low efficiency for the central line scribing, low precision, and big influence degree of the technical level of the scribing worker. The central line scribing device comprises a bracket, two positioning posts which can slide relative to the bracket and can be locked, and a central line sliding cone, wherein the two positioning posts and the central line sliding cone are pairwise parallel, the central line sliding cone is located on the central line position of the two positioning posts, the positioning posts are in step shaft structure, and the central line sliding cone is composed of a middle shaft and two cone body sliding needles at two ends of the central line sliding cone. The utility model has the following beneficial effects of: improving the scribing efficiency and the precision of the central line, and enabling the central line of a parallel surface to be measured by using a central positioning device at any position.
Description
Technical field
The utility model belongs to the machine-building scoring tool, is 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 (sample dashes), 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, workpiece is placed on the platform, parallel with platform or vertical by adjusting a top plane with workpiece, measure the length of two parallel surfaces earlier with steel ruler, calculate the numerical value of half 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 utility model 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 utility model 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, 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 utility model is to be benchmark with two parallel surfaces, under any locus, directly marks center line on workpiece.
The utlity model 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
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.
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), 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 as Fig. 2, shown in Figure 3, the part that diameter is big is used for measuring the parallel surface of (matrix) groove class workpiece, as Fig. 4, shown in Figure 5; Adopt Quenching Treatment, the case hardness height 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 to mark center line on workpiece; 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.Structure commonly used is: make screw thread on support, by 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) of the both sides that slidably also can lock of support (2) and middle sliding bore (4) of center line 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), 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.
