Problems solved by technology

The star-shaped inner star wheel is provided with an inner fairway and an outer fairway on the staggered concave-convex surface of the outer circumference. The shape and position of the inner star wheel are the key dimensions of the inner star wheel, especially the design dimension from the ball center to the end surface of the fairway. During the processing It is difficult to measure accurately with general-purpose measuring tools of conventional structure, and the existing technology can only do relative measurement
Non-quantitative measurement cannot accurately detect product quality and cannot correctly guide production

Abstract

The invention discloses a device for detecting an inner star wheel padded wall center of sphere position, which comprises a positioning seat, an auxiliary axis, a base, a principle axis, a washer, a cage, a holding screw, a gauge stand, a dial test indicator, and a locking screw. The base is connected with the auxiliary axis and the principle axis. The cage and the washer are sheathed on the principle axis together. The positioning seat is provided with two parallel through holes which are matched with the auxiliary axis and the cage in a transitional way. The positioning seat can move up and down corresponding to the base. The middle part of the upper plane of the positioning seat is connected with the gauge stand used for fixing the dial test indicator and the side surface of the positioning seat is provided with a padded wall center of sphere positioning benchmark setting structure which comprises a pin roll, steel ball, a bolt and a cover board. The plane of the base is set as zero position in actual measurement. The deviation value between the actual value and the theoretical value of the detected surface of the inner star wheel away from the center of sphere of the inner star wheel can be detected by moving the positioning seat up and down. The device is especially suitable for being used as the production field witnessed inspections.

Description

technical field [0001] The invention relates to a checking device for detecting the position deviation of mechanical parts, in particular, the invention relates to a device for detecting the position of the ball center of the inner star wheel fairway. Background technique [0002] The inner star wheel is an important component in the car axial drive cage universal joint. The star-shaped inner star wheel is provided with an inner fairway and an outer fairway on the staggered concave-convex surface of the outer periphery. The shape and position of the fairway are the key dimensions of the inner star wheel, especially the design dimension from the ball center to the end surface of the fairway. During the processing It is difficult to carry out accurate measurement with a general-purpose measuring tool of conventional structure, and the prior art can only do relative measurement. Non-quantitative measurement cannot accurately detect product quality and cannot correctly guide pr...
