Embodiment Construction

[0013] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0014] The spherical end surface shape and position inspection tool shown in the accompanying drawings is composed of a mandrel 1, a template 2, a screw 3 and a pin 4. The template 2 in the present invention is a thin plate with a downwardly curved arc detection surface, and the lateral section of the template 2 is knife-edge shaped. The middle section of the mandrel 1 is provided with a radial opening groove, and the depth of the groove is equal to the radius of the mandrel 1. The template 2 fits the bottom surface of the mandrel 1 opening groove on a plane and is fixedly connected with the screw 3 and the pin 4. The central line is coaxial with the axis of the mandrel 1, and the radius of curvature of the arc is equal to the radius of the spherical end surface to be tested. The embodiment is a test tool for detecting the shape and po...

Abstract

The invention discloses a spherical end face shape and position degree detector, which comprises a mandrel, a template, screws and pins, wherein the template is a sheet component and is provided with a knife-edge arc detection surface; the mandrel is provided with a radial opening slot for installing the template, and the depth of the slot is equal to the radius of the mandrel; the flat surface of the template and the bottom surface of the opening slot of the mandrel are attached and are fixedly connected by the screws and the pins, and a vertical center line of the arc of the template is coaxial with an axial line of the mandrel; the radius of curvature of the arc is equal to the radius of the spherical end face to be detected; and the mandrel is in clearance fit with a shaft hole to be detected. The spherical end face shape and position degree detector uses the mandrel as a standard to detect the shape and the position of the spherical end face, has convenient measurement and high detection efficiency, and is particularly suitable to be used as a special on-line detector in large-scale production fields.

Description

technical field [0001] The invention relates to a checker for detecting the shape and position of a curved surface body, in particular, the invention relates to a checker for the shape and position of a spherical end face. Background technique [0002] Because of the curved surface of parts with spherical end faces, general-purpose measuring tools cannot be directly used for shape and position detection during the manufacturing process, and its processing quality is difficult to meet the design requirements. The bevel gear in the automobile differential gear is designed to be spherical due to the structural requirements. In addition to the quality requirements for the shape of the spherical end face, there is also a positional tolerance relative to the bevel gear shaft hole. During the manufacturing process, the spherical end face can only be made using a curve template. It cannot be used to detect the position accuracy of the spherical end surface relative to the shaft hole...
