Abstract
The utility model discloses a belt pulley remover, a four-jaw belt pulley remover with use convenience, good stability, labor saving and high efficiency and includes four quadrangular jaws, with the two front jaws bolted with two back jaws, a pull rod, a stop block and a top rod, and is characterized in that the four jaws are all provided with the pull rod, that the stop block takes the shape of cross axle, that the end of each pull rod is sleeved on each axle end of the cross axle, and that the top rod is treaded with the center of the cross axle stop block. In the structure, the length and distance of each pull rod is the same, without need to adjust the position of the stop block and the tension force of the four pull rod is well-distributed and more powerful, thereby making the disassembly more convenient, efficient, labor-saving and reliable.
Description
1, technical field
The utility model belongs to extracting tool, is suitable for dismantling the belt pulley or other class wheel (dish) that are enclosed within on the axle.
2, background technology
The dismounting belt pulley generally all is to use three-jaw jig, three-jaw to block the wheel limit now, firmly pull outward by manpower, and the ten minutes effort, efficient is low.
My patent that obtains " 00230738.3, four-jaw type belt pulley extracting tool ", in set stops be to link to each other with two pull rod screw, during use, need regulate the stops position, again pull-rod nut is locked, could rotate threaded mandrel then, pull out wheel.Also bother when this structure uses, and because of having only two claws that pull bar is arranged, stability is not high enough, efficient is not high enough, and is laborsaving inadequately.
3, summary of the invention
The utility model purpose provides a kind of easy-to-use, good stability, more laborsaving, belt pulley extracting tool that efficient is high---and be four-jaw type belt pulley extracting tool.
Its purpose realizes by following technical proposals, and it comprises and be tetragonal four claws that the first two claw is connected with back two claw bolts.Also comprise pull bar, stops and push rod, its characteristics are: four claws are equipped with pull bar, and stops is a cross axle-type, and each pull bar tail end is enclosed within each axle head of cross axle respectively, and push rod is threaded with cross axle stops center.
In the above-mentioned structure, the length distance unanimity of each pull bar need not be adjusted the position of stops, and four draw-bar pulls evenly and stronger make that dismounting is more convenient, efficient is high, more laborsaving, good stability.
4, description of drawings:
Fig. 1 is a structural representation of the present utility model
5, the specific embodiment
As shown in Figure 1, the utility model is by four pull bars of four claws (1,2,3,4) (5,6,7,8), and cross axle stops 9 and push rod 10 are formed, and the first two claw 1,2 and back two claws 3,4 are connected through bolt.There is chute 12 each claw both sides for the distance of adjusting between the claw, to adapt to the dismounting of the big or small wheel of difference.Each pull bar one end and claw are connected, and the other end is enclosed within the axle head of cross axle, and threaded mandrel 10 and spider center are for being threaded.During use, the first two claw is positioned at the wheel back side, and back two claws are positioned at the wheel front, and push rod withstands the residing axial end of wheel, rotates push rod then, and wheel is drawn off.Very convenient, advantage, effect are as before chatting.
