Abstract
The invention discloses a vernier caliper for measuring a T-shaped groove. The vernier caliper comprises a main caliper and a vernier which is attached to the main caliper and can slide along the main caliper, wherein a fastening piece for positioning the vernier on the main caliper is arranged on the vernier; at least one set of measuring claw is arranged between the main caliper and the vernier; an inclined angle A is formed between a clamping surface on the end part of the measuring claw and the vertical direction; and an inclined surface which is ended on the clamping surface is correspondingly formed on one side surface of the end part of the measuring claw. According to the vernier caliper for measuring the T-shaped groove, the clamping surface of the measuring claw is matched with a gradient shape design of a workpiece, and the inclined surface which is ended on the clamping surface is correspondingly formed on one side surface of the end part of the measuring claw at the same time, so that the measuring claw can be extremely conveniently clamped into the workpiece, and the measurement efficiency is improved; and in the measuring process, the clamping surface is tightly attached to a measurement surface of the workpiece, so that the measurement accuracy is improved.
Description
Technical field
The present invention relates to a kind of survey instrument, relate in particular to a kind of vernier caliper that is used to measure T type groove.
Background technology
In panoramic measurement instrument family; Vernier caliper is as a kind of high-acruracy survey instrument that is widely used, and it is the extension and the expansion of groove ruler, at present; Vernier caliper is the instrument that measurement length commonly used is gone up in industry; It is made up of the blade and the vernier that can on blade, slide, and blade and vernier all have measuring claw, utilize measuring claw can measure length, interior external diameter and the degree of depth.
Mostly the snap-latch surface of the measuring claw of traditional vernier caliper is the right angle, when measurement has the structure of certain slope, such as the interior external diameter of measuring the T type groove on the T type flange, just exists measuring claw to be difficult for engaging and the not high shortcoming of measuring accuracy like this.
Summary of the invention
The object of the present invention is to provide a kind of vernier caliper that is used to measure T type groove, it has the advantages that measuring accuracy is high and be convenient to the measuring claw engaging, to solve the problem that vernier caliper exists in the prior art.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of vernier caliper that is used to measure T type groove; It comprises main scale and is attached to can be along the vernier of main scale slip on the main scale; Install on the said vernier vernier is positioned the securing member on the main scale, at least one cover is set between said main scale and the vernier measures claw, wherein; The snap-latch surface and the vertical direction of the end of said measurement claw have included angle A, and the span of said included angle A is: 0 °＜A＜90 °.
Especially, on the side of the end of said measurement claw the corresponding inclined-plane that ends at snap-latch surface that offers, so that when measuring, measure claw and snap in workpiece.
Especially, said measurement claw is provided with a cover, and it is interior measuring claw, and the inboard of the end of measuring claw was used to measure internal diameter in said snap-latch surface was arranged at.
Especially, said measurement claw is provided with a cover, and it is the external pelivimetry pawl, and said snap-latch surface is arranged at the outside of the end of external pelivimetry pawl, is used to measure external diameter.
Especially, said included angle A=23 °.
Especially, said securing member is a trip bolt.
Beneficial effect of the present invention does; The snap-latch surface that the compared with prior art said vernier caliper that is used to measure T type groove will be measured claw cooperates the gradient shaped design of workpiece; Correspondence is provided with the inclined-plane that ends at snap-latch surface on a side of the end of measuring claw simultaneously; Not only greatly facilitate the measurement claw and snap in workpiece, improved efficiency of measurement; And when measuring, snap-latch surface is close to the measurement face of workpiece, has improved the precision of measuring.
