Embodiment Construction

[0070] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0071] Such as figure 1 Shown is an embodiment of the coaxiality inspection tool 100 of the present invention. The workpiece 200 detected by the coaxiality inspection tool 100 is as figure 2 As shown, the workpiece 200 includes a workpiece body 201 and a rod portion 202. The workpiece body 201 has an inner cavity 203 sunken inward, and the rod portion 202 is fixedly connected to the workpiece body 201. extend in the same direction. The workpiece 200 may be an inner ball joint, or a part similar to an inner ball joint.

[0072] Such as figure 1 , Figure 4 to Figure 6 As shown, the coaxiality inspection tool 100 includes a support body 1, a base 2 and a dial indicator 3, the support body 1 includes a support block 11 and a plurality of matching parts 12, and the plurality of matching parts 12 are arranged on the outer per...

Abstract

The invention provides a coaxiality test tool. The coaxiality test tool includes a support body, a pedestal and a dial indicator. The support body includes a support block and a plurality of mating parts. The mating parts are arranged on the outer peripheral face of the support block. The mating parts fit with the inner surface of an inner cavity of a working piece body. The central axis of the support block is the rotation symmetric center of the mating parts. The support body is mounted on the pedestal and rotates on the pedestal around the central axis of the support block. The axis of a measurement rod of the dial indicator is perpendicular to the central axis of the support block. When the inner cavity of the work piece sleeves the support block, the head part of the measurement rod of the dial indicator is in contact with the outer peripheral face of the rod part. According to the invention, the work piece is mounted on the support block; through rotating the support body, the coaxiality between the central axis of the inner cavity and the central axis of the rod part can be obtained through numerical change on the dial indicator. The measurement method is simple and the measurement result is accurate. The coaxiality test tool is especially suitable for measurement of coaxiality of components such as a inner ball joint or a component having a shape similar to that of theinner ball joint.

Description

technical field [0001] The invention relates to a coaxiality inspection tool. Background technique [0002] Now some ball cage processing manufacturers have a common problem that the coaxiality between the inner cavity of the inner ball joint shell and the rod part deviates from the technical requirements, which makes subsequent processing or rework impossible, especially for the long rod shell. However, because the inner cavity of the housing is uniformly distributed in the shape of three-column grooves, it is difficult to quickly and accurately measure the coaxiality between the inner cavity of the inner ball joint housing and the rod by existing measuring methods. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coaxiality checking tool in order to overcome the defect in the prior art that the coaxiality between the inner cavity of the inner ball joint housing and the rod is difficult to measure. [0004] Th...
