Abstract
A bearing puller comprises a nut, a pressing plate and a steel tube, and is characterized in that a claw hook seat is installed on a conical screw rod, and two claw hooks are connected with the claw hook seat through cylindrical pins; the lower end of the conical screw rod is a cylinder, the outer side of each claw hook is an arc surface, the lower end of the outer side of each claw hook is a pulling claw protruding outward, a pin hole is formed in a boss above each claw hook, an arc surface with the diameter larger than the diameter of an outer circle of the screw rod is formed above the inner side of each claw hook, a conical surface is formed below the inner side of each claw hook, the arc surface inside each claw hook is mutually matched with the arc surface at the lower end of the conical screw rod, a screw hole matched with the conical screw rod is formed in the middle of the cylindrical claw hook seat, two symmetrical grooves which are matched with the bosses above the claw hooks are formed in the two sides of the lower portion of the claw hook seat, and pin holes are formed in a process platform on the two sides of each groove. According to the bearing puller, smaller bearings in a workpiece can be taken out, and intactness of the workpiece and the bearings can be ensured.
Description
Technical field
The utility model relates to a kind of hardware ﹠ tools, particularly a kind of bearing puller.
Background technology
Multiplex two pawls of instrument or the three-jaw of existing hand disassembly bearing, when bearing during at inside workpiece, these instruments are difficult to play a role, especially when the bearing of inside workpiece hour, be difficult to find suitable instrument that these bearings are taken out.
Summary of the invention
Its purpose of the utility model is: a kind of bearing puller is provided, and it can take out bearing less in the workpiece, and guarantees the intact of workpiece and bearing.
The purpose of this utility model realizes by following approach:
A kind of bearing puller comprises nut, pressing plate and steel pipe, it is characterized in that: the claw hook seat has been installed on the conical screw, and two claw hooks are connected with the claw hook seat by straight pin; The lower end of conical screw is cone, the claw hook outside is arc surface, the lower end in the claw hook outside is outwards protruding pulling claw, the boss of claw hook top is provided with pin-and-hole, the top of claw hook inboard is that diameter is greater than the arc surface of screw rod cylindrical, the below of claw hook inboard is taper seat, taper seat in the claw hook and the taper seat of conical screw lower end cooperatively interact, the screw of the centre of cylindrical claw hook seat for matching with conical screw, the both sides of claw hook seat bottom are provided with the groove of two symmetries that match with the boss of claw hook top, and the technique platform of groove both sides is provided with pin-and-hole.
A kind of bearing puller of the present utility model compared with prior art, it can take out bearing less in the workpiece, and guarantees the intact of workpiece and bearing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Label declaration
1 conical screw, 2 nuts, 3 pressing plates, 4 steel pipes, 5 claw hook seats, 6 straight pins, 7 claw hooks, 8 pulling claws, 9 bearings, 10 workpiece.
The specific embodiment
Below in conjunction with embodiment the utility model is described in more detail.
A kind of bearing puller as shown in Figure 1 comprises nut 2, pressing plate 3 and steel pipe 4, it is characterized in that: 5, two claw hooks of claw hook seat 7 have been installed on the conical screw 1 have been connected with claw hook seat 5 by straight pin 6; The lower end of conical screw 1 is cone, claw hook 7 outsides are arc surface, the lower end in claw hook 7 outsides is outwards protruding pulling claw 8, the boss of claw hook 7 tops is provided with pin-and-hole, the top of claw hook 7 inboards is that diameter is greater than the arc surface of screw rod cylindrical, the below of claw hook 7 inboards is taper seat, taper seat in the claw hook 7 and the taper seat of conical screw 1 lower end cooperatively interact, the screw of the centre of cylindrical claw hook seat 5 for matching with conical screw 1, the both sides of claw hook seat 5 bottoms are provided with the groove of two symmetries that match with the boss of claw hook 7 tops, and the technique platform of groove both sides is provided with pin-and-hole.
During this bearing puller assembling, first two claw hooks 7 are connected with claw hook seat 5 by straight pin 6, again conical screw 1 is up twisted from the below of claw hook seat 5 screws, respectively pressing plate 3, nut 2 are contained on the conical screw 1 afterwards, top and nut-welding with conical screw 1 forms at last, as shown in Figure 1a, if the top of conical screw 1 not with nut-welding, it is tight also can to use double nut to piece together on the top of conical screw 1.
This bearing puller operation principle is: grasp claw hook seat 5, and the conical screw 1 that turns clockwise, the cone of conical screw 1 lower end descends, and two claw hooks 7 are closed up to the center, and steel pipe 4 is placed on the workpiece 10, again claw hook 7 is put into bearing inside; Claw hook seat 5 is fixing, be rotated counterclockwise conical screw 1, the cone of conical screw 1 bottom rises, and struts two claw hooks 7 until pulling claw 8 is held the bearing inner race bottom; Pressing plate 3 is pressed on the steel pipe 4, dextrorotation turn nut 2, just the bearing 9 in the workpiece 10 can be taken out, shown in Fig. 1 b.
