Description

A quick detection angle inspection tool

technical field

The utility model belongs to special inspection equipment, in particular to a quick detection angle inspection tool.

Background technique

Gauge is a special inspection equipment used to measure and evaluate the dimensional quality of parts. In the part production site, the online detection of the parts is realized through the inspection tool. For this reason, the parts need to be accurately installed on the inspection tool, and then the surface and the periphery of the part can be inspected by visual inspection, or a measuring table, or a caliper. The inspection pin or visual inspection is used to visually inspect the holes of different properties on the parts and the connection positions between parts, so as to ensure the rapid judgment of the quality status of parts during production.

The component parts to be tested are assembled and pressed together by two parts bearing sleeves and balance weights to form a single product, in which the inner diameter of the sleeve is formed by a flat plane and the center line at an angle of 7°, as shown in Figure 1 - as shown in Figure 2. According to the actual situation of processing and testing at the production site, it is necessary to be able to measure the angular size directly and quickly. Usually there are several measurement methods:

1. Measurement method of universal angle ruler:

Universal angle gauge is also called angle gauge, vernier angle gauge and universal energy angle gauge. It is an angle measuring tool that uses the principle of vernier reading to measure the angle of the workpiece or draw a line. The tester usually uses the light transmission method to check whether the parts are qualified. The test is greatly affected by external factors, and the operation of the angle ruler is complicated, requiring the operator to have certain measurement experience. Therefore, the actual production site test cannot meet the simple and accurate requirements. .

2. Simple projection measurement method:

Projection measurement enlarges the surface image of the measured workpiece through the shadow of light, and the operator converts the measurement result according to the imaging position relationship. The operator selects points offset due to the differences in each workpiece and the difference in movement, and frequently selects points and Repeated movement causes inaccurate measurements.

3. Three-coordinate measurement method:

Three-coordinate measurement is to put the measured part into its allowable measurement space range, accurately measure the values of the three coordinate positions of the points on the surface of the measured part in the space, and process the coordinate values of these points by computer to form a fitting Measure elements, and obtain their shape, position tolerance and other geometric quantity data through mathematical calculation. The three-coordinate measurement accuracy can reach ±0.05mm, but the three-coordinate is difficult to achieve online detection and judgment of product quality, which does not meet the requirements of mass production testing on the production site for fast and convenient measurement convenience.

Contents of the invention

The purpose of the utility model is to provide a quick detection angle inspection tool and its measurement method, which meets the simple, convenient, fast and intuitive requirements of on-line detection in the production site.

The purpose of this utility model and its main technical problems are achieved by adopting the following technical solutions: a quick detection angle inspection tool, including a base 4, the base 4 includes supports on both sides, and the parts to be tested are supported by mandrels 2 on the supports 1. There is a flat block 3 on the mandrel 2, and the flat block 3 is on the right support, and the pin hole on the part 1 to be tested on the left support is loaded into the plug gauge 5, and the dial indicator 6 is installed on the plug gauge 5.

When in use, the mandrel 2 made according to the size and shape of the inner hole of the shaft sleeve penetrates into the part 1 to be tested, and is placed on the base 4 through the flat stopper 3 on the mandrel 2 to align the angle flat plane of the inner diameter of the shaft sleeve as the reference. On the horizontal plane, the pin hole on the part 1 to be tested is inserted into the plug gauge 5 as the measurement point, and the dial indicator 6 is installed on the plug gauge 5. The vertical distance from the highest point of the plug gauge 5 to the base plane is the detection size.

The principle of the utility model: through the mutual conversion between the angle and the triangular relationship of the plane, the angle of the part can be converted into a value that can be directly read by the measuring tool. Knowing the distance L from the center of the bushing hole to the center of the pin hole, the offset of the flat surface L1, the angle β that needs to be verified, the diameter D of the plug gauge and other related dimensions, the measurement formula is as follows: L*Sinβ+L1+D/2 .

Compared with the prior art, the utility model has obvious advantages and beneficial effects. It can be seen from the above technical solutions that the utility model can effectively monitor the quality of the product in the long-term application, and the customer agrees, which fully demonstrates that the inspection tool can accurately detect the size of the parts. Therefore, this method can be used to popularize the detection of similar angles, and can be used as a checking tool for online detection quickly, easily and intuitively.
