Detailed Description

Example 1

As shown in fig. 1 to 4, the semi-axle flange radial run-out test bench of the present invention comprises a frame 1, wherein the frame 1 is provided with a first supporting component 5 and a second supporting component 6 which are oppositely arranged, the supporting components comprise supporting plates 53, and the top end surfaces of the supporting plates 53 are correspondingly provided with supporting grooves 52;

corresponding to backup pad 53, frame 1 outwards extends and is equipped with spacing fixed subassembly, and spacing fixed subassembly includes the subassembly of bending of upwards bending after outwards extending from backup pad 53 bottom, is equipped with the rotary rod on the subassembly of bending, and the rotary rod is the threaded rod, and the rotary rod is used for the semi-axis 11 spacing fixed.

The inner side surface of the supporting plate 53 is provided with a pair of limiting rollers 55, the limiting rollers 55 are sleeved on the fixing block 54, the fixing block 54 is fixedly connected with a screw 56, and the screw 56 penetrates through the supporting plate 53 and is fixed through a nut 51.

The limiting roller 55 is a bearing, the height of the excircle of the bearing is higher than that of the supporting plate, the center distances of the bearings at the two ends are kept consistent, and the concentricity and the parallelism of the bearings are guaranteed by utilizing the consistency of the center distances, so that the accuracy of the measured half shaft data can be guaranteed.

Wherein, curved subassembly can be including the board 7 of bending, and circular spacing groove 8 is seted up at 7 middle parts of the board of bending, and circular spacing groove 8 corresponds semi-axis 11's ring flange 12 setting, corresponds circular spacing groove 8, and 7 outside outsides of the board of bending extend and are connected with fixed plate 10, run through fixed plate 10 and are equipped with two 9 of rotary rod, and two 9 operating ends of rotary rod are equipped with action bars 14, and action bars 14 are arranged perpendicularly with two 9 of rotary rod.
