Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a cross-sectional view along line AA of fig. 1.

In the figure: 1 fluted disc, 2 steel balls, 3 detection discs, 4 rotary tables, 5 dial indicators, 6 handles and 7 positioning pins.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a device for detecting the included angle error of a fluted disc end face tooth comprises a detection disc 3, wherein the detection disc 3 is positioned and installed on a rotary table 4 through a positioning pin 7, the rotary table 4 is a high-precision rotary table 4, the rotary table 4 is driven through a handle 6, three positioning holes are machined in the detection disc 3 and distributed on the same circumference with the center of the detection disc 3 as the circle center, the included angle between the three positioning holes is 120 degrees, steel balls 2 are respectively installed on orifices of the three positioning holes, the steel balls 2 on the three positioning holes are consistent in size, specifically, the bottoms of the steel balls 2 are connected with the detection disc 3 into a whole through screws, when in detection, a fluted disc 1 to be detected is placed above the steel balls 2, the fluted disc 1 is detected and data are recorded through a dial indicator 5, and then whether the fluted disc 1 is qualified or not is judged through the recorded data of the dial indicator 5, the device is ingenious in design, the investment cost is low.

The detection principle is as follows:

if the error of the included angle of the end face teeth of the fluted disc 1 is zero, the data detected by the dial indicator 5 after the fluted disc 1 is positioned on the steel ball 2 is zero; similarly, if the included angle of the end face teeth of the fluted disc 1 has an error, a data is obtained after the detection by the dial indicator 5, and the data can be obtained by the calculation of the geometric relationship according to the principle: a certain end face tooth included angle error corresponds to end face run-out data, so that end face run-out data b corresponding to the maximum end face tooth included angle error a required by a drawing can be obtained and used as standard data, and if only a maximum group of data in detection is compared with the run-out data b, qualified products are used if the data are smaller than the standard data b, and unqualified products are used if the data are larger than the standard data b.

And (3) detection process:

A. firstly, positioning three tooth grooves of a fluted disc 1 to be detected on three steel balls 2; then a dial indicator 5 is arranged on the plane of the fluted disc 1; rotating the high-precision rotary table 4 by rotating the handle 6 for 360 degrees, observing the change of the reading of the dial indicator 5 and recording the data, which is a first group of data;

B. taking the fluted disc 1 to be detected off the steel balls 2, clockwise rotating the fluted disc 1 by 40 degrees, and positioning the three tooth grooves of the fluted disc 1 on the three steel balls 2; placing the dial indicator 5 on the plane of the fluted disc 1; the rotating handle 6 rotates the high-precision rotary table 4 for 360 degrees, and simultaneously, the change of the reading of the dial indicator 5 is observed and the data is recorded, which is a second group of data.

C. Taking the fluted disc 1 to be detected off the steel balls 2, rotating the fluted disc 1 clockwise by 40 degrees, and positioning the three tooth grooves of the fluted disc 1 on the three steel balls 2; then a dial indicator 5 is arranged on the plane of the fluted disc 1; rotating the high-precision rotary table 4 by rotating the handle 6 for 360 degrees, observing the change of the reading of the dial indicator 5 and recording the data, which is a third group of data;

D. and selecting the largest group of data from the three groups of data, namely the end face runout, to compare with the standard data, wherein the data smaller than the standard data are qualified products, and the data larger than the standard data are unqualified products.

The application provides a 1 detection device of fluted disc design benefit, it is high and detect the convenience to detect the precision, compares the check out test set of specialty, and this application only needs to drop into very little expense just can detect the position precision of 1 terminal surface tooth of fluted disc, greatly reduced the manufacturing cost of fluted disc 1.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
