Floating bush used for inspecting mechanical parts

Abstract

The present invention discloses a floating bush used for inspecting mechanical parts, which consists of a fixed sleeve seat, a fixed sleeve, a movable sleeve and a movable sleeve fixing ring which have unified or parallel axes. The vertical direction is the axis directions of the fixed sleeve seat and the fixed sleeve, the radius of the upper end of the movable sleeve after expanding outwards is greater than the radius of an axis hole of the fixed sleeve, the lower end of the movable sleeve after passing through the axis hole of the fixed sleeve is connected with the movable sleeve fixing ring, and the outside diameter of the part of the movable sleeve passing through the axis hole of the fixed sleeve is smaller than the diameter of the axis hole of the fixed sleeve; the lower end of the fixed sleeve is connected with the upper end of the fixed sleeve seat; and the underside of an axis hole of the movable sleeve is provided with coaxial measurement positioning holes A with smaller diameters, an axis hole of the fixed sleeve seat is a measurement positioning hole B, and the diameters of the measurement positioning hole B of the fixed sleeve seat and the measurement positioning holes A of the movable sleeve are the same. When the floating bush is used for inspecting the parts, the movable sleeve used for connecting a through stop pin can move in an allowable tolerance range so that the quality inspection of the parts is more accurate, effective and reasonable.

Description

technical field [0001] The invention relates to an inspection component for inspecting mechanical parts, in particular to a floating bush used for inspecting mechanical parts matched with a stop pin, and belongs to the production field of inspection accessories for inspecting the quality of mechanical parts. Background technique [0002] In many heavy industry production industries, such as the automobile (including parts) manufacturing industry, the quality requirements for each part are relatively high, so there are special inspection agencies for quality inspection of different parts. This inspection agency Generally, it is a large-scale inspection platform. By installing different inspection instruments at different three-dimensional positions on the inspection platform, the purpose of quality inspection for parts of different shapes and sizes is realized. [0003] Among the above-mentioned inspection devices for inspecting the quality of parts, there is a special inspec...

Problems solved by technology

In the existing products, the size of the positioning seat and the hole on the seat are fixed, and the defect is that the only position detection standard is formed after the connection of the stop pin and the positioning seat, as long as the position of the detected part is slightly different from the standard position , it will lead to the judgment that the detected parts are unqualified products, but in fact, any product is allowed to have a certain tolerance in practical applications, so existing products and qualified parts with certain errors may be inspected as unqualified parts , resulting in qualified parts being reworked or scrapped, resulting in waste of manpower, material resources and time, which is not conducive to the rapid development of modern industry
