Abstract
The invention discloses a three-jaw puller which comprises three pull jaws, a puller seat and a lead screw. The pull jaws are movably arranged on the puller seat, a pull hook which is bent inwardly is arranged at one end of each pull jaw, the puller seat is connected with the lead screw in a threaded manner, three mounting frames are peripherally uniformly distributed on the puller seat, a plurality of mounting holes are formed in each mounting frame, and the pull jaws are arranged in the mounting holes via bolts and nuts. The three-jaw puller has the advantage that the three-jaw puller is applicable to detaching articles such as bearings with various sizes.
Description
Technical field
The present invention relates to the hardware & tools field, relate in particular to a kind of Three-claw pull-horse.
Background technology
Three-claw pull-horse, be mainly used to the bearing of damage, shaft coupling etc. are disassembled vertically from axle.Existing Three-claw pull-horse is difficult to be applicable to the object dismounting of sizes.
Summary of the invention
Technical problem to be solved by this invention is: a kind of Three-claw pull-horse that can be applicable to the objects such as the bearing dismounting of sizes is provided.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of Three-claw pull-horse, comprise three pulling claws, draw horse seat, screw mandrel, pulling claw is movably arranged on and draws on the horse seat, pulling claw one end is provided with aduncate drag hook, draws between horse seat and screw mandrel and is connected by screw thread, and described drawing on the horse seat circumferentially is evenly equipped with three installing racks, installing rack is provided with some installing holes, and described pulling claw is arranged in installing hole by bolt and nut.
As a kind of preferred scheme, described drawing between horse seat and pulling claw is provided with spring.
As a kind of preferred scheme, described leading screw tail end is equipped with force application rod.
As a kind of preferred scheme, the other end of described pulling claw is provided with outside drag hook.
As a kind of preferred scheme, described pulling claw is provided with spring mounting hole, and described drawing on the horse seat circumferentially is evenly equipped with three installation projections, installs on projection and also is provided with spring mounting hole, and described spring is arranged on pulling claw and draws between the horse seat by the hook at two ends.
Advantage of the present invention is: because installing rack is provided with some installing holes, pulling claw can need to be fixed in different installing holes according to using, thereby goes for the dismounting of the parts such as bearing of more size.
Be provided with spring owing to drawing between horse seat and pulling claw, make and draw horse to catch pulling claw difficult drop-off after object, facilitated use.
Because described leading screw tail end is equipped with force application rod, facilitate user's rotating threaded shaft.
Because the other end of described pulling claw is provided with outside drag hook, while needing, the user can be arranged on the leading screw commutation to draw in the horse seat, thereby makes Ben Lama be applicable to the more dismounting of multiple component.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In Fig. 1: 1. pulling claw, 2. draw the horse seat, 3. screw mandrel, 4. installing rack, 5. spring, 6. force application rod, 7. install projection.
