The purpose of the utility model can be realized by the following technical scheme:
the utility model provides a bearing extracting tool, includes the support body, transversely be fixed with the regulation pole on the support body, it has the supporting shoe to slide on the regulation pole, the support body bottom is rotated through the pivot and is connected with two at least fixed hooks, it has the lead screw to alternate perpendicularly on the support body, be close to fixed hook department's thread bush on the lead screw and be equipped with the kicking block.
As a further aspect of the present invention: the tail of the fixed hook is provided with a bending part.
As a further aspect of the present invention: the shape of the top block is conical.
As a further aspect of the present invention: still threaded connection has the elasticity piece on the supporting shoe, the elasticity piece supports with adjusting the pole to press and touches.
The utility model has the advantages that:
its advantage lies in can reduce to the utmost and dismantle in-process bearing damage, and avoids the drawback that traditional puller can only dismantle bearing for the axle.
Drawings
The present invention will be further described with reference to the accompanying drawings.
FIG. 1 is a schematic view of the present invention;
fig. 2 is a schematic sectional structure of the present invention.
In the figure: 1. a frame body; 2. adjusting a rod; 3. a support block; 4. a tightening member; 5. a fixed hook; 51. a bending section; 6. a screw rod; 7. a top block; 8. and a bearing.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
In a first embodiment, please refer to fig. 1-2, the present invention provides a bearing dismounting tool, which includes a frame body 1;
an adjusting rod 2 is transversely fixed on the frame body 1;
wherein, the shape of the adjusting rod 2 can be round, diamond or strip, etc.
A supporting block 3 is arranged on the adjusting rod 2 in a sliding way;
wherein, the supporting block 3 is shaped like a bar or a column.
The bottom of the frame body 1 is rotatably connected with at least two fixed hooks 5 through a rotating shaft;
wherein, the middle of the fixed hook 5 protrudes outwards;
wherein, the tail part of the fixed hook 5 is provided with a bending part 51;
a lead screw 6 is vertically inserted into the frame body 1, and a top block 7 is screwed on the lead screw 6 and close to the fixed hook 5;
wherein the top block 7 may be tapered in shape.
In the second embodiment, please refer to fig. 1-2, the present invention provides a bearing dismounting tool, which includes a frame body 1;
an adjusting rod 2 is transversely fixed on the frame body 1;
the shape of the adjusting rod 2 can be round, diamond or strip.
A supporting block 3 is arranged on the adjusting rod 2 in a sliding way;
wherein, the supporting block 3 is shaped like a bar or a column;
wherein, the supporting block 3 is also connected with a loosening member 4 in a threaded manner, and the loosening member 4 is abutted and contacted with the adjusting rod 2;
wherein the tightening element 4 may be a bolt.
The bottom of the frame body 1 is rotatably connected with at least two fixed hooks 5 through a rotating shaft;
wherein, the middle part of the fixed hook 5 protrudes outwards;
wherein, the tail part of the fixed hook 5 is provided with a bending part 51;
a lead screw 6 is vertically inserted into the frame body 1, and a top block 7 is screwed on the lead screw 6 and close to the fixed hook 5;
wherein the top block 7 may be tapered in shape.
According to the device, the movable supporting block 3 is arranged on the adjusting rod 2, and when the bearing 8 for the hole is disassembled, the position of the supporting block 3 is adjusted according to the outer ring of the mounting hole of the bearing 8, so that effective support can be obtained during disassembly.
The device is characterized in that a jacking block 7 is arranged on a screw rod 6, and the position of the jacking block 7 on the screw rod 6 can be adjusted according to the size of an inner ring of a bearing 8. The fixing hook 5 is prevented from being removed when the bearing 8 for the hole is removed.
When the bearing 8 for the shaft needs to be disassembled, only the fixing hook 5 is disassembled and reversely assembled.
The patent design of the invention is realized by the following methods:
1. when the hole bearing 8 is removed, the position of the supporting block 3 is adjusted according to the outer ring of the mounting hole of the bearing 8. So that effective support can be obtained during disassembly; and adjusting the position of the jacking block 7 on the screw rod 6 according to the size of the inner ring of the bearing 8. The fixing hook 5 is prevented from being removed when the bearing 8 for the hole is removed.
