Special gauge for detecting size of inner fairway of three-pin shaft fork

Abstract

The invention discloses a special gauge for detecting a size of an inner fairway of a three-pin shaft fork. Thespecial gauge comprises a measuring part and a data display part; a lower guide rail seat 15 is connected with a crossed roller guide rail 28, the crossed roller guide rail 28 is connected with an upper guide rail seat 14, and a positioning rod 12 is connected with the upper guide rail seat 14; a cushion column 1 is connected with a measuring panel 11, the measuring panel 11 is connected with the measuring seat 5, and the measuring seat 5 is connected with a measuring lever 9 through a compression spring 33. A measuring head 8 is installed on the positioning rod 12, and the displacement value of the measuring head 8 is transmitted to a meter measuring head 24 through the measuring lever 9 so that the value can be obtained through a measuring meter 37. The special gauge is convenient and fast, is simple to operate, can effectively solve the problems of insufficient repeatability and reproducibility of a conventional three-coordinate measurement method for the critical dimension in the three-pin shaft fork, and improves the repeatability and reproducibility of the measurement dimension precision and the working efficiency of dimension measurement.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to a special inspection tool for the detection of the inner ballway size of the three-pin shaft fork Background technique [0002] The three-pin shaft fork is an important part of the universal joint transmission shaft. The size of the ballway determines the clearance with the three-pin shaft roller, and further determines the stability and service life of the transmission. The traditional detection methods mostly use shakers and three-coordinate detection. This kind of detection efficiency is relatively low, and the repeatability and reproducibility are difficult to be guaranteed. Therefore, a special inspection tool for the detection of the inner ballway size of the three-pin shaft fork is designed, so that the detection process becomes more convenient and fast, and the operation is simple, while ensuring its detection. Accuracy and guaranteed repeatability and reproducibility. ...
