Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
A simple bevel gear back taper angle detection tool, please refer to fig. 1, its invention points are:
comprises two parts of a detection tool body and a centering shaft 3. The detection tool main body is a U-shaped clamping plate structure consisting of a transverse edge 1 and two parallel vertical edges 2, inclined planes 2-1 are symmetrically arranged on the inner sides of the lower ends of the two vertical edges, the inclination angles of the inclined planes on the two sides are consistent with the back taper angle of a standard bevel gear sample piece, and the two inclined planes are detection surfaces in contact with the back taper surface of the bevel gear to realize the detection of the back taper angle. The centering shaft is vertically and fixedly connected with the center part of the transverse edge, and the diameter of the centering shaft is the same as that of the circular groove at the end part of the bevel gear to be detected. The centering shaft has the following functions: the center of the detection tool is ensured to coincide with the center of the bevel gear so as to determine the detection accuracy.
In the above structure: the centering shaft is connected with the transverse edge in a vertically adjustable mode. The fine adjustment of the vertical position of the centering shaft can be realized, so that two inclined planes on the vertical side are in contact with the conical surface of the bevel gear after the lower end of the centering shaft is in contact with the circular groove on the end surface of the bevel gear.
The preferable installation mode of the centering shaft is as follows: the upper end part of the centering shaft is provided with an external thread section, the center of the transverse edge is provided with a mounting hole with internal threads, and the upper end part of the centering shaft is connected with the mounting hole of the transverse edge through threads. The connection mode has the advantages of simple structure and convenience in adjustment.
The simple bevel gear back taper angle detection tool has the following use description:
two inclined planes on two vertical edges of the detection tool body are abutted against the back conical surface 101 of the bevel gear 100 to be detected, the up-down position of the centering shaft is finely adjusted, and after the lower end of the centering shaft is contacted with the end face circular groove of the bevel gear, the upper edge lines of the two inclined planes are overlapped with the upper edge line of the back conical surface of the bevel gear; and then observing whether the inclined plane and the back conical surface are completely attached or not by focusing, wherein the angle of the back conical surface is qualified under the condition of no gap in the complete attachment, and the angle of the back conical surface is unqualified under the condition of the occurrence of the gap.
Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims, and therefore, the scope of the present invention is not limited to the disclosure of the embodiments and the accompanying drawings.
