Roundness and cylindricity measurement device

Abstract

The invention discloses a roundness and cylindricity measurement device. The device comprises a base, a measurement system arranged on the base, and a rotating system; the measurement system comprisesa horizontal movement portion, a vertical movement portion connected with the horizontal movement portion, and a detecting portion arranged on the vertical movement portion; the detecting portion includes an angle adjusting device and a laser detector; the horizontal movement portion controls the laser detector to perform fore and aft movement in a horizontal direction; the vertical movement portion controls the laser detector to move up and down; and the angle adjusting device is provided with a third motor and a first turntable and adjust an angle between the laser detector and the horizontal direction, so that the deviation detection of the circular shape of the annular protruding portion of a cylindrical product to be measured can be realized. The device of the invention has a wider application range.

Description

technical field [0001] The invention relates to a measuring device for cylindrical products, in particular to a non-contact measuring device for roundness and cylindricity. Background technique [0002] Cylindrical products such as bearings often need to collect relevant data on the deviation between the product to be tested and the circular shape, such as roundness, concentricity, coaxiality, etc., to check whether the product meets the requirements. If the manual detection method is adopted one by one, it will not only take time and effort, increase the labor cost, but also affect the production efficiency; using the measuring equipment of roundness and cylindricity, the object to be measured is loaded on the rotary table, and then the rotary table rotates, At the same time, the contact stylus is used to detect the surface position of the measured rotating body, etc., so as to collect the surface position data of the product to be tested, and then measure and calculate the...

Problems solved by technology

If the manual detection method is adopted one by one, it will not only take time and effort, increase the labor cost, but also affect the production efficiency; using the measuring equipment of roundness and cylindricity, the object to be measured is loaded on the rotary table, and then the rotary table rotates, At the same time, the contact stylus is used to detect the surface position of the measured rotating body, etc., so as to collect the surface position data of the product to be tested, and then measure and calculate the roundness and cylindricity. The use of the stylus needs to contact the workpiece and interact with the surface of the workpiece. Sometimes it will cause damage to the surface of the workpiece. At the same time, long-term work will also cause the aging of the stylus and reduce the sensitivity. It is necessary to replace the stylus

[0003] In recent years, non-contact roundness and cylindricity measuring devices have gradually entered the market. For example, eddy current displacement sensors, laser sensors, etc. are used as detection components, which can well protect the surface of the product to be tested, but the product to be tested is not a regular cylinder , and there is a raised part on the cylindrical surface, for the upper or lower surface of the raised part, the non-contact measuring device cannot perform effective roundness detection
