Description

Technical Field

[0001] The utility model relates to a machining detection tool, more specifically, to a rapid detection device for the external spline runout of shaft parts. Background Art

[0002] A large runout error of the external spline of a shaft part will lead to a large tooth profile error, thereby reducing the fitting accuracy of the spline, increasing the vibration and noise of the rotor during operation, and reducing mechanical performance and reliability. Therefore, the runout of the external spline is particularly important. The runout of the external spline of a shaft part is generally measured relative to the center of the two shafts, and the runout requirements are measured in combination with these two reference elements.

[0003] In the existing technology, three-coordinate testing is used. The instrument is expensive and has high operating requirements. It requires personnel with a certain level of professionalism to conduct the testing. The testing cost is high, the testing procedure is complicated, and it takes a long time. Only one item is tested per shift, and the testing frequency is low. It is not easy to control the quality of the production process in a timely manner.

[0004] If online detection is used, the center holes at both ends of the part are used for positioning, and a measuring rod of matching specifications is used to move the part inside each tooth and rotate the part with a micrometer one circle to measure the radial runout of the external spline. The detection takes too long. Utility Model Content

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0019] like Figure 1 and Figure 2As shown, the external spline runout rapid detection device for shaft parts includes a gear runout tester 1, which includes a pair of oppositely arranged top points 11, a threaded column 5 is provided on one side of the gear runout tester 1, and an instrument seat 51 that can be raised and lowered is provided on the threaded column 5. A detachable micrometer 2 is provided on the instrument seat 51, and the micrometer 2 is matched with an external external spline sleeve 3, and the external spline sleeve 3 is sleeved and connected with the shaft part 4.

[0021] It should be noted that the outer circle of the step 32 is annular. The handle portion 33 is annular.

[0022] The following is a method for quickly detecting the external spline runout of shaft parts. The steps are:

[0023] S1, slowly insert the external spline sleeve 3 into the spline part 42 of the shaft part 4;

[0024] S2, slowly insert the center holes 41 at both ends of the shaft part 4 with the external spline sleeve 3 into the two tops 11 of the gear runout inspection instrument 1, and directly insert the shaft part 4 to realize the positioning of the two center holes of the shaft part 4;
