Description

Measuring device for detecting machined parts

Technical Field

The utility model relates to a machined part detects technical field, specifically is a machined part detects and uses measuring device.

Background

As is known, the production process of a machine refers to the whole process of making a product from raw materials (or semi-finished products). For machine production, the raw material transportation and preservation, production preparation, blank manufacturing, part processing and heat treatment, product assembly and debugging, painting and packaging and the like are included. The content of the production process is very wide, modern enterprises organize production and guide production by using the principle and method of system engineering, and the production process is regarded as a production system with input and output. In the production process, all the processes of changing the shape, size, position, property, etc. of the production object into a finished product or a semi-finished product are called as a process. It is an integral part of the production process.

According to the existing machining part required by a manufacturer, after a front cover processes a corresponding plane, a central hole and other parts in a machining center, the front cover is transferred to a lathe to process two arcs. According to the design requirement, the distance between the side edges of the left arc and the right arc and the center datum point of the center hole has the requirement of position tolerance. After the arc is machined by the subsequent lathe, monitoring is needed, and whether the whole offset exists or not is within the range of position tolerance relative to the center of the center hole machined in the previous procedure when the two arcs are machined. Because the center of the circular hole is used as a reference point, a distance measuring tool commonly used on site such as a caliper cannot place a zero point on a theoretical reference point in the air, and whether the position size is qualified cannot be accurately detected. Usually, the position of the circle center can be calculated by measuring the hole wall of the circular hole by a three-coordinate measuring instrument, then the edges of the two circular arcs are respectively measured, and the distance from the circular arc edge to the reference point of the circle center is calculated to check whether the requirement of position tolerance is met. The three-coordinate measuring machine is adopted, a constant-temperature detection chamber is needed, the detection time is long, the operation of a professional is required, the direct field realization cannot be realized, and the timely detection of each piece cannot be realized. Therefore, a measuring device for detecting a machined part is provided.
