Abstract

The invention provides a wheel radial positioning device consisting of a base, a bearing, a round disc, sliding bases, a clamping jaw base, ejector blocks, springs, an ejector shaft, an air cylinder, end face positioning blocks, flat key and an ejector head, wherein the three sliding bases and the three end face positioning blocks are uniformly distributed on the round disc; the air cylinder is connected with the base through the bearing; the round disc is fixedly arranged on the air cylinder; the sliding bases and the end face positioning blocks are mounted on the round disc; and the ejector shaft uses the flat keys at the two inner sides of the sliding bases to guide and are reset through the springs. A wheel is subjected to an end face positioning by using the three end face positioning blocks, and the three ejector blocks can be used for clamping the wheel from the inner side of a wheel edge in a three-point positioning manner, so that radial positioning is carried out. When the wheel radial positioning device provided by the invention is in use, the different radial positioning requirements of the wheel can be met; and the technical requirements on an operator are low. Meanwhile, the wheel radial positioning device has the characteristics of simple structure, low manufacturing cost and precision capable of meeting the clamping requirements.

Description

technical field [0001] The invention relates to a positioning device, in particular to a wheel radial positioning device. Background technique [0002] During the processing of automobile wheels, it is often necessary to use the front of the wheel as the axial and radial positioning reference to measure the coaxiality of the rim or rim. Because it is an assembly line production, it is necessary to ensure the fast clamping of the wheels; at the same time, it must be suitable for wheels of different sizes, so the stroke of the fixture is required to be large enough, and the corresponding large stroke will undoubtedly increase the difficulty of manufacturing the fixture. The traditional large-stroke pneumatic chuck has high cost, poor precision, poor operability in the field of wheel alignment applications, is not suitable for various wheel types with different shapes, and has low efficiency. Contents of the invention [0003] The object of the present invention is to provid...
