Abstract
A kind of height gauge line measuring jaw disclosed in the utility model, comprise the line measuring jaw be fastened on by fixed frame on height gauge measuring claw, line measuring jaw comprises the connected edge of a knife and connecting rod, the other end of connecting rod is fixed on height gauge measuring claw, the cutter head position shape of the edge of a knife is convex polygon or circular arc, and arbitrary contact point of the edge of a knife and workpiece is rule.A kind of height gauge line measuring jaw of the present utility model changes the edge of a knife shape of line measuring jaw into convex polygon or circular arc, thus make to rule measuring jaw and workpiece when carrying out point cantact on line measuring jaw any point can realize the function of point cantact line with workpiece, thus solve the straight knife mouth rapid wear of existing line measuring jaw, affect the shortcoming in service life.
Description
Technical field
The utility model belongs to height gauge component technology field, is specifically related to a kind of height gauge line measuring jaw.
Background technology
Height gauge is widely used in industry-by-industry as accurate metering outfit, and as scoring tool often and height gauge cooperating rule measuring jaw, the edge of a knife of the line measuring jaw that market is sold now is all linear, in the process utilizing the line of line measuring jaw, the edge of a knife of line measuring jaw only have two ends cusps can and workpiece carry out point cantact and rule, if Long-Time Service will cause line measuring jaw serious wear, service life shortens.
Utility model content
The purpose of this utility model is to provide a kind of height gauge to rule measuring jaw, solves existing height gauge line measuring jaw and easily to wear and tear when ruling the problem causing service life shorter.
The technical scheme that the utility model adopts is: a kind of height gauge line measuring jaw, comprise the line measuring jaw be fastened on by fixed frame on height gauge measuring claw, line measuring jaw comprises the connected edge of a knife and connecting rod, the other end of connecting rod is fixed on height gauge measuring claw, the cutter head position shape of the edge of a knife is convex polygon or circular arc, and arbitrary contact point of the edge of a knife and workpiece is rule.
Feature of the present utility model is also,
The cutter head position of the edge of a knife is coated with one deck hard alloy layer.
The beneficial effects of the utility model are: a kind of height gauge line measuring jaw of the present utility model changes the edge of a knife shape of line measuring jaw into convex polygon or circular arc, thus make to rule measuring jaw and workpiece when carrying out point cantact on line measuring jaw any point can realize the function of point cantact line with workpiece, thus solve the straight knife mouth rapid wear of existing line measuring jaw, affect the shortcoming in service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of height gauge line measuring jaw of the present utility model.
In figure, 1. height gauge, 2. rule measuring jaw, 3. workpiece, 21. edges of a knife, 22. connecting rods.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
The structure of a kind of height gauge line measuring jaw that the utility model provides as shown in Figure 1, comprise the line measuring jaw 2 be fastened on by fixed frame on height gauge 1 measuring claw, line measuring jaw 2 comprises the connected edge of a knife 21 and connecting rod 22, the other end of connecting rod 22 is fixed on height gauge 1 measuring claw, the cutter head position shape of the edge of a knife 21 is convex polygon or circular arc, and arbitrary contact point of the edge of a knife and workpiece is rule.
Example, the shape of connecting rod 22 can be any shape such as straight-bar or knee.
In order to increase the service life of line measuring jaw, under the prerequisite not changing the edge of a knife 21 shape, be coated with one deck hard alloy layer in the cutter head position of the edge of a knife 21 to increase its abrasion resistance properties.
During use, height gauge 1 and workpiece 3 are placed in identical platform, one end fixed frame of the connecting rod 22 of line measuring jaw 2 is fixed tightly on height gauge 1 measuring claw, adjust line height, can rule on workpiece, in scratching process, the convex polygon cutter head of the edge of a knife 21 has multiple cusp can carry out point cantact with workpiece 3, and any point on the cutter head of circular arc can realize point cantact with workpiece, thus solve the problem of the line measuring jaw quick abrasion of existing straight knife mouth structure, by further increasing the service life of single cusp on the edge of a knife 21 at the coated hard alloy layer in cutter head position of the edge of a knife 21, extend the service life of line measuring jaw.
Claims (2)
1. a height gauge line measuring jaw, it is characterized in that, comprise the line measuring jaw (2) be fastened on by fixed frame on height gauge (1) measuring claw, described line measuring jaw (2) comprises the connected edge of a knife (21) and connecting rod (22), the other end of described connecting rod (22) is fixed on height gauge (1) measuring claw, the cutter head position shape of the described edge of a knife (21) is convex polygon or circular arc, and arbitrary contact point of the edge of a knife and workpiece is rule.
2. a kind of height gauge line measuring jaw as claimed in claim 1, it is characterized in that, the cutter head position of the described edge of a knife (21) is coated with one deck hard alloy layer.
