Abstract

Disclosed is a shaft part detection mechanism. The mechanism comprises a bottom plate base (1), bearing support blocks (2) and an optical axis (3). Two bearing support blocks (2) are respectively disposed on the bottom plate base (1) through chamfer head screws (6). The mechanism is characterized in that bearings (4) are respectively disposed on the corresponding bearing support blocks (2) through the optical axis (3). External circles of the two bearings (4) share the same axial lead. The mechanism helps to allow a part to rotate in a measurement process, and measures jumping, coaxiality, cylindricity and other form & position tolerances of various shaft parts by adjusting displacement of the axis, so that one mechanism achieves a goal of detecting various parts.

Description

Axial workpiece detection architecture

Technical field

The utility model relates to machine industry, particularly about axial workpiece, detects cylindricity, right alignment, the structure of the form and position tolerance such as beat.

Background technology

Current machine industry is beated for axial workpiece, the detection of the form and position tolerances such as right alignment is mainly to use V-block to support, while touching with being coupling due to V-block, it is sliding friction, when the axial workpiece quality detecting is larger, friction force is larger, therefore part rotates difficulty, easily produce and beat, thereby affect the precision detecting.

Summary of the invention

For above deficiency, the purpose of this utility model is to provide a kind of axial workpiece detection architecture that replaces sliding friction with kinetic friction, is on bottom block, to be provided with two bearings that axle center is consistent, the displacement of its axle center, for beating of Parts Measurement, the form and position tolerances such as right alignment.

The technical solution of the utility model is achieved in the following ways: axial workpiece detection architecture, comprise bottom block, bearings piece, bearing and optical axis, two bearings pieces are arranged on respectively on bottom block by sunk screw, it is characterized in that: described bearing is arranged on respectively on corresponding bearings piece by optical axis, and the cylindrical of two bearings has same axial line.

Described bearings piece is bolted on bottom block.

Described bearing is Series of Ball Bearing.

The utility model structure, not only helps the rotation of part in measuring process, and for various parts, by the displacement of its axle center, for beating of Parts Measurement, the form and position tolerances such as right alignment and cylindricity.Thereby realize a device, the object that various workpieces detects.

Fig. 1 is front view of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the left view of Fig. 1.

Embodiment

By Fig. 1, Fig. 2, Fig. 3, known that axial workpiece detection architecture structural representation of the present utility model is mainly that bottom block 1, bearings piece 2, optical axis 3, bearing 4, bolt 5 and sunk screw 6 form.

By Fig. 2, being known, is the side vertical view of Fig. 1.Two bearings pieces 2 are arranged on respectively on bottom block 1 by sunk screw 6, and the cylindrical that by optical axis 34, two bearings 4 of bearing is installed on each described bearings piece 2 has same axial line.

By Fig. 3, known, described bearings piece is bolted on bottom block.Described bearing 4 is Series of Ball Bearings.Bearings piece 2 is arranged on bottom block 1 by sunk screw 6, bearing 4 is arranged on bearings piece 2 by optical axis 3, tested part is placed on two two bearings pieces 2, the face of cylinder of part is contacted with bearing top circle, when two face of cylinder external diameters are in different size, adjusting is arranged on the bolt 5 of four jiaos of bottom blocks, regulates a side of small diameter, makes the axis that detects axle in same level position.

When detecting axial workpiece, two pick-up units are placed on platform, axial workpiece is placed on above bearing 4, when the supporting surface diameter of axial workpiece is different, by the bolt 5 at four angles on rotating bottom board seat 1, adjust the height of axle one side, make the axis that detects axle be positioned at a surface level, the axle detecting when the last time during with current not of uniform size the causing of axle external diameter of detecting, can unclamp sunk screw 6, regulates distance between two bearings pieces 2 and the external diameter of detected axle.
