Description

Center measuring tool

Technical Field

The utility model relates to a measuring tool, in particular to a central measuring tool.

Background

In the actual production process, the problem of measuring the center distance between two holes is often encountered. However, in the conventional technology, the center distance measurement is inaccurate, and even the deviation is too large. The hole center distance needs to prepare a ruler before measurement, the straight line distance between the hole edge and the hole edge between the two holes is measured firstly, then the diameter of the hole is measured, and the diameter of the hole and the edge distance of the two holes are added to obtain the center distance of the hole.

In order to solve the above problems, we have made a series of improvements.

SUMMERY OF THE UTILITY MODEL

It is an object of the present invention to provide a centering tool that overcomes the above-mentioned disadvantages and drawbacks of the prior art.

A central measurement tool comprising: the scale comprises a graduated scale, a scale surface groove body, a reference hanging hammer and a conical hanging hammer, wherein the scale surface groove body is arranged on the graduated scale, the reference hanging hammer and the conical hanging hammer are arranged on the scale surface groove body, the reference hanging hammer is fixed at the 0-scale position of the graduated scale, and the conical hanging hammer is connected with the scale surface groove body in a sliding mode.

Further, the ruler surface groove body is of a groove body structure, and a sliding groove is formed in the inner wall of the ruler surface groove body.

Further, the reference drop hammer comprises: the scale comprises a fixing part and a first hanging hammer, wherein one end of the fixing part is connected with the bottom of the first hanging hammer, the other end of the fixing part is connected with a scale surface groove body, and the vertex of a cone of the first hanging hammer and the 0 scale position of the graduated scale are on the same straight line.

Further, the conical drop hammer comprises: the clamping groove piece is connected with the bottom of the second hanging hammer, and two sides of the clamping groove piece are connected with the sliding groove of the ruler surface groove body.

The utility model has the beneficial effects that:

compared with the prior art, the two-point identification can be accurately formed by adding the reference hanging hammer and the conical hanging hammer, and the distance between two holes to be measured can be quickly and accurately read by reading the two-point identification.

Detailed Description

The present invention will be further described with reference to the following examples. It should be understood that the following examples are illustrative only and are not intended to limit the scope of the present invention.

Example 1

FIG. 1 is a schematic structural diagram of the present invention. Fig. 2 is a side view of the present invention.

As shown in fig. 1 and 2, a center measuring tool includes: the scale comprises a graduated scale 100, a scale surface groove body 200, a reference hanging hammer 300 and a conical hanging hammer 400, wherein the scale surface groove body 200 is arranged on the graduated scale 100, the reference hanging hammer 300 and the conical hanging hammer 400 are arranged on the scale surface groove body 200, the reference hanging hammer 300 is fixed at the 0-scale position of the graduated scale 100, and the conical hanging hammer 400 is in sliding connection with the scale surface groove body 200.

The ruler surface groove body 200 is of a groove body structure, and a sliding groove is formed in the inner wall of the ruler surface groove body 200.

The reference drop hammer 300 includes: the fixing member 310 and the first hanging hammer 320, one end of the fixing member 310 is connected with the bottom of the first hanging hammer 320, the other end of the fixing member 310 is connected with the scale face slot body 200, and the vertex of the cone of the first hanging hammer 320 is on the same straight line with the 0-scale position of the graduated scale 100.

The conical drop hammer 400 includes: the clamping groove piece 410 is connected with the bottom of the second hanging hammer 420, and the two sides of the clamping groove piece 410 are connected with the sliding groove of the ruler face groove body 200.

The utility model is improved on the basis of the traditional graduated scale, a scale surface groove body 200 is additionally arranged on the graduated scale, a reference drop hammer 300 is fixed at the 0-scale position, and the cone vertex of the reference drop hammer 300 and the 0-scale position are in the same straight line. A sliding conical drop weight 400 is placed in the middle of the ruler center. During measurement, the datum hanging hammer 300 is placed in a first hole, the conical hanging hammer 400 is moved to the second hole surface, the hanging hammers are placed, data can be read through scales on the ruler surface, data reading can be completed at one time, two hanging hammers are flatly placed at the center position of each hole during measurement, the ruler is guaranteed to be horizontal, inclination is prevented, reading accuracy is affected, a reading vertical line is carved at the center position of the tail end of the sliding hammer, scales on the ruler can be easily aligned, corresponding numbers can be directly read during hole center distance measurement, the hole center distance is calculated without measuring the linear distance between two hole edges and then by a hole center diameter method, hole center distance measuring time is greatly saved, the hole center distance can be perfectly measured at one time, and the two holes are directly clamped by the conical hanging hammers, direct readings were taken on the scale surface.

While the present invention has been described with reference to the specific embodiments, the present invention is not limited thereto, and various changes may be made without departing from the spirit of the present invention.
