Embodiment Construction

[0016] Combine below Figure 1 to Figure 3 And further illustrate the technical scheme of the present invention by specific embodiment:

[0017] An auxiliary inspection tool for hole position, including a base 1, positioning pins 3 and three pins 2, the base 1 is a cylindrical structure, the center of the base 1 is provided with a set of holes 1-3, and the bearing method The reference outer diameter of the blue plate is matched, the base 1 is set on the bearing flange 4 through the sleeve hole 1-3, the inner diameter of the sleeve hole 1-3 is equal to the outer diameter of the bearing flange 4, along the edge of the base 1 There is a first positioning hole 1-1 in the axial direction of the base 1. The first positioning hole 1-1 matches the positioning hole on the bearing flange 4, and the positioning pins 3 pass through the bearing flange 4 in turn. The positioning hole and the first positioning hole 1-1 on the base play the role of positioning, preventing the base and the be...

Abstract

A hole position degree auxiliary gauge belongs to the technical field of bearing manufacturing and detection. The invention aims to solve the problems of long detection period, inconvenience in field quality control and risk of over-poor product quality due to the fact that three-coordinate detection is generally adopted for product detection in the prior art. A hole position degree auxiliary gauge comprises a base, a positioning pin and three pins, the base is of a cylindrical structure, a sleeve hole is formed in the center of the base, a first positioning hole is formed in the edge of the base in the axis direction of the base, and three non-equal second positioning holes are formed in the side wall of the base in the radial direction of the base in a penetrating mode. The positioning pin is inserted into the first positioning hole, and a pin is inserted into each second positioning hole. The method is mainly used for detecting the precision of the blind hole in the bearing flange.

Description

technical field [0001] The invention belongs to the technical field of bearing manufacturing and testing, and in particular relates to an auxiliary checking tool for hole position. Background technique [0002] At present, the new bearing structure design in the aviation bearing industry has the characteristics of complex structure and integration. There is 1 reference hole and 19 weight reduction holes on the bearing flange, and there are 3 non-equal radial blind holes on the outer diameter. There is a positional relationship between each blind hole and the reference hole on the bearing flange. At the same time, the axial position of the blind hole is required to be 10mm: the product has high precision requirements, and the product flange reference hole size dispersion requirement is 0.012mm. for The radial hole size dispersion of the outer diameter is 0.012mm, and the position accuracy According to the above situation, the product processing is difficult, the outer dia...
