Abstract
The invention relates to a mousing-hook wheel puller, which comprises a support and more than two pulling claw arms, wherein the rear end of any pulling claw arm is fixedly connected to the support; a claw hook is hinged to the front end of each pulling claw arm; an inclined step is arranged on the outer side of any claw hook; a threaded groove is formed in the inclined step; all claw hooks are distributed along the peripheral direction; a sleeve ring is arranged on the outer sides of all claw hooks; and internal threads are arranged in the sleeve ring and are conical threads or the inner wall of the rear part of the sleeve ring is in a conical shape. According to the mousing-hook wheel puller, the sleeve ring is arranged on the outer sides of all claw hooks, and the claw hooks are locked by utilizing conical surfaces and the threads between the outer sides of the claw hooks and the sleeve ring and can be locked with the edge of the back side of a circular workpiece reliably, so that slipping is avoided. The mousing-hook wheel puller is simple and reliable in structure and convenient to install and operate.
Description
Technical field
The present invention relates to mechanical field, relate in particular to from the instrument of axle dismounting round piece, particularly a kind of mousing-hook pulley extractor.
Background technology
Pulley extractor is widely used in circle shape workpiece such as disengage gear, bearing, belt pulley from the axle.Pulley extractor is provided with plural pulling claw along circumferential in a support; In carriage center screw rod is set, during use, pulling claw is hooked the dorsal part edge of round shape workpiece; The front end of screw rod is withstood axle head; Rotary screw strengthens the distance between support and the axle head through screw thread pair, and round piece is left behind from axle vertically.In the prior art, the dorsal part of part circle shape workpiece is less with the step between the axle, and perhaps the dorsal part of round shape workpiece is domatic, and pulling claw produces at the dorsal part of circle shape workpiece easily and radially slides and come off, and causes dismounting to fail.
Summary of the invention
The object of the present invention is to provide a kind of mousing-hook pulley extractor, the pulling claw that described this mousing-hook pulley extractor will solve pulley extractor in the prior art produces the technical problem that radially slides, causes the dismounting failure at the dorsal part edge of circle shape workpiece easily.
This mousing-hook pulley extractor of the present invention comprises the pulling claw arm of a support and two above numbers, and the rear end of any pulling claw arm all is fixedly connected on the described support; Wherein, the front end of any described pulling claw arm all is hinged with a claw hook separately, and the outside of any claw hook is provided with sloping platform rank; Described sloping platform is provided with thread groove in the rank; All claw hook along the circumferential direction distributes, and all the arranged outside of claw hook has a collar, is provided with internal thread in the described collar; Described internal thread is a tapered tread, and perhaps the rear inside wall of the collar is taper.
Further; Described support is in the form of annular discs; The center of support is coaxially arranged with the protrusion cylinder, and the place, axle center of the center of support and described protrusion cylinder is provided with screwed hole, is provided with a push rod in the described screwed hole; Described push rod is connected with the protrusion cylinder with support through screw thread pair, and the rear end of push rod is connected with drive rod.
Further, the front end of described push rod is provided with top.
Operation principle of the present invention is: the dorsal part edge that claw hook is hooked round shape workpiece; The collar is locked through screw thread and claw hook in the outside of claw hook; Be taper owing to be provided with the rear inside wall of the tapered tread or the collar in the collar, so claw hook will justify the dorsal part edge locking of shape workpiece, can slippage.The front end of push rod is withstood the workpiece axle head,, strengthen the distance between support and the workpiece axle head, round piece is left behind from axle vertically through drive rod rotation push rod.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention is at the claw hook arranged outside collar, utilizes the conical surface and screw-threaded coupling claw hook between the claw hook outside and the collar, claw hook can with the dorsal part edge positive lock of justifying the shape workpiece, can slippage.The present invention is simple and reliable for structure, convenient installation and operation.

The specific embodiment
Embodiment 1
As shown in Figure 1, mousing-hook pulley extractor of the present invention comprises the pulling claw arm 2 of a support 1 and two above numbers; The rear end of any pulling claw arm 2 all is fixedly connected on the described support 1, and wherein, the front end of any described pulling claw arm 2 all is hinged with a claw hook 3 separately; The outside of any claw hook 3 is provided with sloping platform rank, and described sloping platform is provided with thread groove in the rank, and all claw hook 3 along the circumferential direction distributes; All the arranged outside of claw hook 3 has a collar 4; Be provided with internal thread in the described collar 4, described internal thread is a tapered tread, and perhaps the rear inside wall of the collar 4 is taper.
Further; Described support 1 is in the form of annular discs; The center of support 1 is coaxially arranged with protrusion cylinder 5, and the place, axle center of the center of support 1 and described protrusion cylinder 5 is provided with screwed hole, is provided with a push rod 6 in the described screwed hole; Described push rod 6 is connected with protrusion cylinder 5 with support 1 through screw thread pair, and the rear end of push rod 6 is connected with drive rod 7.
Further, the front end of described push rod 6 is provided with top.
The course of work of present embodiment is: the dorsal part edge that claw hook 3 is hooked round shape workpiece; The collar 4 is locked through screw thread and claw hook 3 in the outside of claw hook 3; Be taper owing to be provided with the rear inside wall of the tapered tread or the collar 4 in the collar 4; Therefore claw hook 3 will be justified the dorsal part edge locking of shape workpiece, can slippage.The front end of push rod 6 is withstood the workpiece axle head,, strengthen the distance between support 1 and the workpiece axle head, round piece is left behind from axle vertically through drive rod 7 rotation push rods 6.
