Detailed Description

Embodiments of the present invention will be described in detail below with reference to fig. 1-5.

A hub straight-through type bulging positioning device comprises a positioning base 1 and a bulging bolt 2 arranged on the positioning base 1, wherein the positioning base 1 comprises a chassis 4, a support column 5 is connected to the middle position of the upper portion of the chassis 4, an expansion sleeve 6 is arranged on the upper portion of the support column 5, a plurality of expansion joints 7 are arranged on the expansion sleeve 6, the expansion joints 7 divide the expansion sleeve 6 into a plurality of bulging lobes 8, an inclined surface 9 is arranged on the inner side of the top of each bulging lobe 8, the inclined surface 9 inclines inwards and downwards, a threaded hole 11 is arranged in the middle position of the upper portion of the support column 5, the upper end of each expansion joint 7 is flush with the upper end of the corresponding expansion sleeve 6, the lower end of each expansion joint 7 is a certain distance away from the top of the corresponding threaded hole 11, the lower end of each expansion joint 7 is circular, so that each bulging lobe 8 has larger flexibility, the bulging bolt 2 comprises a bulging block 12, the lower portion of each bulging block 12 is connected with an extension rod 14, and the lower portion of each extension rod 14 is connected with a screw rod 15, screw rod 15 threaded connection is in screw hole 11, and bulging piece 12 upper portion is connected with nut 13, and bulging piece 12 periphery laminating inclined plane 9 sets up, and 6 outside covers of expansion sleeve are equipped with calibration ring 3.

Preferably, a plurality of adjusting holes 10 are arranged on the chassis 4, and the adjusting holes 10 are elliptical holes.

Preferably, the number of the adjusting holes 10 is three, and the three adjusting holes 10 are uniformly distributed.

Preferably, the number of the expansion joints 7 is four, and the expansion joints 7 are uniformly distributed on the expansion sleeve 6.

In the specific implementation, a calibration ring 3 is machined, and the inner diameter of the calibration ring 3 is the same as the diameter of the shaft hole 17 in the hub 16. The calibration ring 3 is sleeved outside the expansion sleeve 6, the nut 13 is screwed to drive the expansion block 12, the extension rod 14 and the screw rod 15 to rotate together, and the screw rod 15 is in threaded fit with the threaded hole 11, so that the expansion block 12 moves downwards while rotating. The expansion block 12 is attached to the inclined surface 9 to move, and the expansion valve 8 is extruded outwards in the downward moving process, so that the expansion valve 8 is expanded.
