Description
Technical Field
The utility model relates to a frock field specifically is an inspection device for work piece concentricity.
Background
Coaxiality is an important technical index for evaluating a cylindrical workpiece, and coaxiality errors directly influence the assembly and use of the workpiece. However, when the measured element axis of the workpiece is extremely short, it is very difficult to evaluate the coaxiality of the workpiece, and the concentricity is usually used for evaluation.
The coaxiality error directly influences the matching precision and the use condition of the workpiece. The concentricity error is the eccentricity which is the eccentricity of the circle center reflected by the coaxiality error on the section, and the concentricity error is the offset degree of the circle center.
Concentricity is a special form of coaxiality. When the measured element is the circle center (point), the hole on the thin workpiece or the axis of the shaft, the measured axis is regarded as the measured point, and the coaxiality of the measured axis and the hole on the thin workpiece to the reference axis is the concentricity. Therefore, the measurement of the concentricity can be used for projection measurement;
the traditional concentricity inspection device cannot simultaneously inspect the concentricity of a plurality of cylindrical workpieces with different specifications, and has a single function.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, an inspection apparatus for workpiece concentricity comprises an apparatus main body 1, three concentric circles are arranged at the center of the apparatus main body 1, the concentric circles are a first inspection hole 2, a second inspection hole 3 and a third inspection hole 4, respectively, and an eccentric inspection hole 5 is opened at one side of the lower end close to the third inspection hole 4.
The diameters of the first detection hole 2, the second detection hole 3 and the third detection hole 4 are 2CM, 1CM and 0.2CM respectively.
The four corner positions of the apparatus main body 1 are all rhombuses.
The diameter of the eccentric detecting hole 5 is 0.18 CM.
Spiral lines are engraved on the inner walls of the eccentric detection holes 5 of the first detection hole 2, the second detection hole 3 and the third detection hole 4.
When the concentricity of the cylindrical workpiece is detected, firstly, a proper detection hole is selected according to the specification of the detected cylindrical workpiece, and because the spiral lines are engraved on the inner walls of the eccentric detection holes of the first detection hole, the second detection hole and the third detection hole, the detection holes with different diameters can be replaced according to the diameters of different cylindrical workpieces, and the detection holes can be rotated to finish the disassembly and the installation when the detection holes are replaced;
then, the cylindrical workpiece starts to rotate to obtain an evaluation circle model, meanwhile, based on the reference circle model of the cylindrical workpiece to be detected, mutual comparison is carried out, the position error between the marked reference circle model and the evaluation circle model is not more than 0.1, the qualified degree of concentricity can be detected, and whether the cylindrical workpiece is a qualified product or a defective product is finally determined.
