Example Embodiment

[0019] The present invention will be further described in detail below with reference to the embodiments given in the drawings.

[0020] See figure 1 As shown, a quick measurement of ultra-precision roundness tooling includes a tooling body 1 and a ball fixing device 2. The tooling body 1 is a cylindrical hollow structure with a vacuum chamber 3 at the upper part and a buffer chamber 4 at the lower part. The vacuum chamber 3 and The buffer chamber 4 is separated by a partition 5; the vacuum chamber 3 is provided with a cylindrical vacuum pump accommodating chamber 6, the vacuum pump accommodating chamber 6 is fixed in the vacuum chamber 3 by sixteen shock-absorbing springs 7; the vacuum pump accommodating chamber 6 is provided with a vacuum pump 8. The vacuum pump 8 is fixed in the vacuum pump storage bin 6 through eight tension springs 9; the exhaust port of the vacuum pump 8 is connected with an exhaust pipe 10, which passes through the vacuum pump storage bin 6 and the buffer ...

Abstract

The invention relates to an ultra-precise rapid circularity measuring tool which comprises a tool body and a ball fixing device. The tool body is of a hollow structure, the upper portion of the tool body includes a vacumm chamber, the lower portion of the tool body includes a buffering chamber, and the vacuum chamber is separated from the buffering chamber via a separator plate; the vacumm chamber is internally provided with a vacuum pump accommodating cavity which is fixed in the vacuum chamber via damping springs; and the vacuum pump accommodating cavity is internally provided with a vacuum pump which is fixed in the vacuum pump accommodating cavity via extension springs. The ultra-precise rapid circularity measuring tool reduces vibration of a circularity test during motion greatly via dual damping, the ball to be tested is fixed in a vacuum absorption manner instead of using an external binder, the balls of different materials can be tested, and the circularity of the ball can be determined rapidly and accurately.

Description

technical field [0001] The invention relates to a quick measurement of ultra-precision roundness tooling, which belongs to the field of optical instruments. Background technique [0002] High-precision spheres are important components in roundness meters, gyroscopes, bearings and precision measurement, and are often used as the benchmark for precision measurement. They play a very important role in precision equipment and precision machining, especially in ball bearings. The key part of the ball bearing, the progress of the bearing ball, directly affects the technical indicators such as the motion accuracy, noise and service life of the ball bearing, which in turn affects the performance of equipment and instruments; in addition, high-precision spheres are also widely used in high-precision optical instruments and equipment middle. [0003] Precision machining of high-precision spheres and accurate roundness testing are two major problems that have plagued the industry for ...
