TECHNICAL FIELD

The present invention relates to a wheel machining device, and in particular to a high-precision turning device.

BACKGROUND ART

Multiple wheel detection items exist in the automobile wheel manufacturing industry, sometimes the wheel needs to turn for a certain angle to be detected, and the turning precision of the wheel is an important factor for influencing the detection precision. Therefore, the present invention provides a high-precision turning device.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a high-precision turning device.

To achieve the object described above, a technical solution of the present invention is as follows: a high-precision turning device is composed of a base plate, a base, a support A, a lead screw, a turning block, a support B, a coupling, and a servomotor. The support A, the support B and the base are fixed on the base plate, the lead screw is mounted above the base plate through the support A and the support B, and the coupling connects the lead screw with the servomotor. An empty groove is formed in the center of the bottom surface of the base, and the lead screw passes through the empty groove; symmetrical T-shaped annular grooves are formed in two sides of the interior of the base, two symmetrical T-shaped annular columns are arranged on the lower end face of the turning block, and the T-shaped annular columns can be inserted into the T-shaped annular grooves; and the structure of a central position of the lower end face of the turning block is annular teeth, and the annular teeth are meshed with the lead screw. The servomotor drives the lead screw to rotate, and by virtue of meshing matching of the annular teeth and the lead screw, the turning block can turn along the centers of the T-shaped annular grooves in the base.

During actual use, the servomotor starts working, and the lead screw rotates; by virtue of the meshing matching of the annular teeth and the lead screw, the lead screw drives the turning block to turn along the centers of the T-shaped annular grooves in the base; and by controlling the revolutions of the servomotor, the turning block can highly precisely turn for any angles.

In use, the high-precision turning device provided by the present invention can meet the requirement on high-precision turning and has the characteristics of simple structure, reliable work, high turning precision and the like.
