Abstract

The utility model discloses a high-precision tapered outer circle inspection tool, which comprises a measuring body, a base, and a first dial indicator and a second dial indicator arranged on the base. The first dial indicator and the second thousand indicator The distance between the gauges is a fixed value, and there is a height difference between the first gauge and the second gauge. The detection tool first puts the standard part of the measurement body into the base, adjusts the positions on the dials of the first and second dial gauges, and then puts in other workpieces to be tested after calibration, and directly looks at the first thousand The position of the two pointers on the sub-meter and the dial of the second dial gauge is sufficient, and the difference between the two dial gauges is the measured value; Improve the detection efficiency, and suitable for on-site inspection. Processors can check while processing, and the value is clear, and it is quite convenient for debugging. You can make corresponding adjustments by looking at the value of the hands.

Description

High-precision taper outer circle inspection tool

technical field

The utility model belongs to the field of design and manufacture of testing tools, in particular to a high-precision tapered outer circle testing tool.

Background technique

At present, the taper fit is widely used in the machinery industry because of its tight fit and easy disassembly, especially in the heavy machinery industry. However, when the taper fit is not good, such as excessive taper error and low taper contact rate, it will cause excessive fit. Early damage is not conducive to long-term use. Therefore, the taper inspection checkpoint is particularly important in the manufacturing process. Most of the existing high-precision taper outer circle detection tools are projected by three-dimensional coordinates and high-precision projectors, which are very inefficient and costly, and are not suitable for on-site detection of large quantities of parts.

Utility model content

The purpose of this utility model is to solve the problem that most of the existing high-precision tapered outer circle inspection tools are projected by three coordinates and high-precision projectors, the efficiency is very low, and the cost is huge, and it is not suitable for on-site inspection of a large number of pieces. A high-precision tapered outer circle inspection tool has the advantages of convenient detection, accurate data, high efficiency and low cost.

The technical solution of the utility model is achieved in the following way: a high-precision tapered outer circle inspection tool includes a measuring body, a base, and a first dial indicator and a second dial indicator arranged on the base. The distance between the dial gauge and the second dial gauge is a fixed value, and there is a height difference between the first dial gauge and the second dial gauge.

Compared with the prior art, the utility model has the following advantages: firstly put the standard parts of the measuring body into the base, and adjust the positions on the dials of the first dial indicator and the second dial indicator. The purpose of this step is to First calibrate the two dial gauges so that they can be used to measure other workpieces to be detected; then put other workpieces to be detected, and directly look at the positions of the two pointers on the dials of the first dial gauge and the second dial gauge. Yes, the difference between the two dial gauges is the measured value; the above-mentioned method of testing the taper of the same measuring body through two dial gauges greatly improves the detection efficiency and is suitable for on-site inspection. Processors can check while processing, and the value is clear, and it is quite convenient for debugging. You can make corresponding adjustments by looking at the value of the hands.

detailed description

As shown in Figure 1, it is a high-precision tapered outer circle inspection tool, including a measuring body 1, a base 2, and a first dial gauge 3 and a second dial gauge 4 arranged on the base, the first dial gauge The distance between the submeter and the second dial gauge is a fixed value, and there is a height difference between the first dial gauge and the second dial gauge.

The working principle of the high-precision taper outer circle inspection tool: first put the standard part of the measuring body into the base, and adjust the positions on the dials of the first dial gauge and the second dial gauge. The purpose of this step is to first place the two After the first dial indicator is calibrated, it can be used to measure other workpieces to be tested; then put other workpieces to be tested, and just look at the positions of the two pointers on the dials of the first and second dial gauges. The difference between the two dial gauges is the measured value; the above-mentioned method of testing the taper of the same measuring body through two dial gauges greatly improves the detection efficiency and is suitable for on-site inspection. Processors can check while processing, and the value is clear, and it is quite convenient for debugging. You can make corresponding adjustments by looking at the value of the hands.

Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Apparently, the technical solutions of the present invention are not limited to the above-mentioned embodiments, and many variations are possible. All deformations that a person skilled in the art can derive or associate directly from the content disclosed in the utility model shall be considered as the protection scope of the utility model.
