Abstract
The invention discloses an antiskid wheel pusher, which comprises a bracket and more than two pull claws, wherein pull hooks are arranged at the front ends of the pull claws; the bracket is disk-shaped; radial slots are formed in the bracket along a circumferential direction at equal angles, and the number of radial slots is the same as that of pull hooks; the rear ends of the pull claws respectively penetrate through the corresponding radial slots and are connected with the bracket through corresponding pin shafts; a protruded cylinder is coaxially arranged in the center of the bracket; a threaded hole is formed in the center of the bracket and the axis of the protruded cylinder; a mandrel is arranged in the threaded hole and connected with the protruded cylinder through a thread pair and the bracket; the rear end of the mandrel is connected with a driving rod; and a limiting ring is sleeved at the outer periphery of the protruded cylinder and positioned between the rear ends of the pull claws and the protruded cylinder. According to the antiskid wheel pusher, arms of the pull claws extend to the rear side of the bracket; the limiting ring is arranged between the rear ends of the pull claws and the protruded cylinder, so that the front ends of the pull claws can be prevented from sliding towards the outer side of the circumference along the radial direction through the limiting ring; and the antiskid wheel pusher is simple in structure, reliable and convenient to assemble 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 anti-skidding 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, pulling claw produces at the dorsal part edge of circle shape workpiece easily and radially slides, so that comes off, and causes the dismounting failure.
Summary of the invention
The object of the present invention is to provide a kind of anti-skidding pulley extractor, the pulling claw that described this anti-skidding 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 anti-skidding pulley extractor of the present invention comprises the pulling claw of a support and two above numbers, and the front end of any described pulling claw is provided with drag hook; Wherein, Described support is in the form of annular discs, in the support along the circumferential direction equal angles be provided with the same number of radial slot with described pulling claw, the rear end of any pulling claw is all passed a described radial slot separately and is connected with support through a bearing pin separately; The center of support is coaxially arranged with the protrusion cylinder; 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, and described push rod is connected with the protrusion cylinder with support through screw thread pair; The rear end of push rod is connected with drive rod; Be arranged with a spacing ring on the excircle of protrusion cylinder, the internal diameter of described spacing ring cooperates with the external diameter of protrusion cylinder, and spacing ring is between the rear end and protrusion cylinder of pulling claw.
Further, be provided with screw thread between described spacing ring and the protrusion cylinder.
Further, the front end of described push rod is provided with top.
Operation principle of the present invention is: the dorsal part edge that pulling claw is hooked round shape workpiece; The front end of push rod is withstood the workpiece axle head, and the spacing ring of selecting external diameter to equate with the external diameter of circle shape workpiece is inserted in spacing ring between the rear end and protrusion cylinder of pulling claw; Spacing ring stops the front end edge of pulling claw radially outside circumference, to slide; Through drive rod rotation push rod, strengthen the distance between support and the workpiece axle head, round piece is left behind from axle vertically.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention extends to the rear side of support with the pulling claw arm, between the protrusion cylinder of the rear end of pulling claw and support rear side spacing ring is set, and utilizes spacing ring to prevent that the front end edge of pulling claw from radially sliding outside circumference, and is simple and reliable for structure, convenient installation and operation.

Fig. 1 is the structural representation of anti-skidding pulley extractor of the present invention.
The specific embodiment
Embodiment 1
As shown in Figure 1, anti-skidding pulley extractor of the present invention comprises the pulling claw 2 of a support 1 and two above numbers; The front end of any described pulling claw 2 is provided with drag hook, and wherein, described support 1 is in the form of annular discs; In the support 1 along the circumferential direction equal angles be provided with the same number of radial slot 3 with described pulling claw 2; The rear end of any pulling claw 2 is all passed a described radial slot 3 separately and is connected with support 1 through a bearing pin 4 separately, and 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; Be 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, is arranged with a spacing ring 8 on the excircle of protrusion cylinder 5; The internal diameter of described spacing ring 8 cooperates with the external diameter of protrusion cylinder 5, and spacing ring 8 is between the rear end and protrusion cylinder 5 of pulling claw 2.
Further, be provided with screw thread between described spacing ring 8 and the protrusion cylinder 5.
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 pulling claw 2 is hooked round shape workpiece; The front end of push rod 6 is withstood the workpiece axle head, and the spacing ring 8 of selecting external diameter to equate with the external diameter of circle shape workpiece is inserted in spacing ring 8 between the rear end and protrusion cylinder 5 of pulling claw 2; Spacing ring 8 stops the front end edge of pulling claw 2 radially outside circumference, to slide; Through drive rod 7 rotation push rods 6, strengthen the distance between support 1 and the workpiece axle head, round piece is left behind from axle vertically.
