T-shaped groove 53 is connected to the bottom of lifting column 7 through a sliding nut 54, specifically: the bottom of the lifting column 7 is provided with a threaded rod, the threaded rod is connected with a sliding nut 54 through threads, the sliding nut 54 can slide in the T-shaped groove 53, and the lifting column 7 can be adjusted relative to the center of the base 5 in this way, so that the relative position between the lifting columns 7 can be adjusted. The T-shaped groove 53 of this embodiment has six, i.e., the lifting column 7 has six.
Specifically, the method comprises the following steps: the lifting column 7 comprises an inner screw 71 and a threaded sleeve 72 which are connected through screw threads, the lower end of the threaded sleeve 72 is connected through screw threads with the sliding nut 54, wherein the inner screw 71 is provided with a scale 711 for displaying the height of the lifting column 7.
The oil cylinder 4 of the embodiment is also connected with a manual pump 8 for driving the oil cylinder 4 to act.
The base plate 1 is further provided with locking means for locking the base 5. Preferably, the locking device comprises a bracket 11 connected to the base plate 1, a positioning ring 52 connected to the side of the base 5, and a top thread 12 connected to the bracket 11 by a screw, wherein the top thread 12 is connected to the positioning ring 52 when the base 5 is in the locking state. The jackscrew 12 attachment face of the retaining ring 52 is also provided with anti-slip projections for increasing the friction between the jackscrew 12 and the retaining ring 52.
The rotatable concrete structure between bottom plate 1, base 5 is: and a wear-resistant layer 6 is arranged between the two, and the wear-resistant layer 6 can be made of materials with high strength and small friction coefficient, such as: nylon, polytetrafluoroethylene. The center of the base 5 is connected to the base plate 1 through a center shaft 51, and similarly, the center shaft 51 passes through the abrasion resistant layer 6.
The sliding locking device comprises a rack 41, the cross beam 3 is provided with a kidney-shaped hole 32, the lower surface of the cross beam is provided with a toothed plate 31, the oil cylinder 4 is connected to the rack 41 through a pull rod 43, the pull rod 43 penetrates through the kidney-shaped hole 32, when the oil cylinder 4 is in a sliding locking state, the rack 41 is connected to the toothed plate 31 and used for preventing the oil cylinder 4 from sliding, and when the oil cylinder 4 is in a slidable state, the rack 41 is separated from the toothed plate 31.
In order to meet the pressing requirements of shafts or bearings with different specifications, the end part of the piston rod of the oil cylinder 4 of the embodiment is also provided with a detachable presser foot 42.
In order to adjust the distance between the cross beam 3 and the bottom plate 1, the column 2 of the present embodiment is connected to the cross beam 3 by nuts 21, and the nuts 21 are provided on the upper and lower surfaces of the cross beam 3, so that the height of the cross beam 3 can be adjusted by rotating the two nuts 21.
During the use, when the axle is dismantled from the gear to the needs, realize the support to different gears through the height and the relative position of adjusting each lift post 7, can satisfy the support requirement of different size gears like this. The gear is horizontally placed, the shaft inside the gear is vertically placed at the moment, the piston rod of the oil cylinder 4 is aligned with the end part of the shaft, the oil cylinder 4 is driven to extend through the manual pump 8, the presser foot 42 presses the end part of the shaft, and the shaft can be separated from the gear. In the above process, when the oil cylinder 4 is in the non-pressing state, the rack 41 is disengaged from the toothed plate 31 under the action of gravity, and in the pressing state, the locking can be realized through the matching of the rack 41 and the toothed plate 31.
As shown in fig. 4, fig. 4 shows a gear 10 with bearings inside, which can be supported by a plurality of lifting columns 7 when the bearings inside need to be removed. The matching presser foot 42 is selected according to the size of the bearing (the presser foot 42 is preferably pressed on the outer ring of the bearing, which can protect the bearing), and when the diameter of the bearing is smaller, the presser foot 42 matched with the size of the outer ring of the bearing can be used for pressing. However, if the diameter of the bearing is large, the presser foot 42 cannot fully cover the outer race of the bearing. The adjustment of the position of the presser foot 42 (the dotted circle in the figure indicates the pressing point of the presser foot 42) with respect to the workpiece can be achieved in conjunction with the rotation of the base 5 by adjusting the position of the oil cylinder 4 (the large arrow in fig. 4 indicates the adjustment direction of the oil cylinder 4), and then the locking of the base 5 is achieved by rotating the jackscrew 12.
As shown in fig. 5: in fig. 5 a, b, c show the disassembly sequence, where 9 shows the gear to be disassembled and 91 shows the shaft to be disassembled mounted in its center. When the cross section of the presser foot 42 is larger than the inner hole of the gear, the presser foot 42 with smaller specification can be replaced (fig. 5b to 5 c), so that the presser foot 42 can enter the inner hole of the gear for further disassembly. When the shape of the part to be disassembled is irregular, for example, a bearing in the gearbox is disassembled, the gearbox is not in a regular shape, and the plurality of lifting columns 7 can be matched with the outer contour of the gearbox by adjusting the height difference and the relative position of each lifting column 7, so that the box body of the gearbox can be supported.
Compared with the prior art, this embodiment can support not equidimension part to can satisfy the support of irregular part, press the in-process of dismantling, the horizontal slip of hydro-cylinder 4 and the rotation of base 5 make presser foot 42 can form one and can cover the different two-dimensional plane of pressing the position, make presser foot 42 act on the different positions of waiting to dismantle the part, reach better dismantlement effect.
