Detailed Description
Embodiments of the present invention will be described in detail below with reference to fig. 1-4.
The utility model provides an aluminum alloy wheel hub open bulging location drilling equipment, including unable adjustment base 1, unable adjustment base 1 includes chassis 2 and dabber 4, dabber 4 is connected perpendicularly and is put in the central point on 1 upper portion of unable adjustment base, 1 top intermediate position of unable adjustment base sets up threaded hole 5, 4 upper portions of dabber are provided with shaft shoulder 6, the cover is equipped with support ring 8 on the dabber 4, 8 lower extremes of support ring support are supported and are leaned on shaft shoulder 6 and set up, 8 upper portions of support ring are connected with go-between 12, go-between 12 upper portions are connected with inflation cover 7, the internal diameter of inflation cover 7 reduces from top to bottom gradually, a plurality of expansion joints 13 have been seted up on the inflation cover 7, be provided with in the inflation cover 7 and support tight piece 9, support the inner wall setting of tight piece 9 periphery laminating inflation cover 7, support tight piece 9 sub-unit connection has screw rod 10, support tight piece 9 upper portion and seted up connecting hole 11.
Preferably, the fixed base 1 is provided with a plurality of adjusting holes 3.
Preferably, three adjusting holes 3 are arranged, and the three adjusting holes 3 are uniformly distributed.
Preferably, the number of the expansion joints 13 is twelve. The upper end of the expansion joint 13 is flush with the left end of the expansion sleeve 7, and the right end of the expansion joint 13 is at a certain distance from the connecting ring 12.
Preferably, the connection hole 11 is a hexagonal hole.
Preferably, the bottom of the fixed base 1 is provided with a lightening groove.
The rim 15 of the hub is placed on the support table 14 with the spindle 4 passing through the axial bore 16 of the hub. The expansion sleeve 7 is sleeved on the mandrel 4, so that the support ring 8 is propped against the shaft shoulder 6, and then the propping block 9 is placed in the expansion sleeve 7. Due to the matching of the screw 10 and the threaded hole 5, the expansion sleeve 7 can be continuously close to the chassis 2 when the abutting block 9 is rotated by the hexagon socket wrench, and the abutting block 9 extrudes the expansion sleeve 7 to expand outwards. The expansion sleeve 7 is expanded to abut against the inner wall of the shaft hole 16, so that the hub is fixed and positioned, and the subsequent drilling of the hub is ready.
