Abstract

A pump paired-wheel puller comprises a pump shaft, a clamp plate, a paired wheel, support plates, a screw rod, nuts, screws and a filling block, wherein the pump shaft is arranged on the paired wheel, the clamp plate is provided with a slot, the filling block is arranged in the slot, the paired wheel is clamped by the clamp plate and the filling plate, the front end of the screw is fixed on the clamp plate, the screw passes through the support plate, and is provided with male thread, the male thread is connected with the nut, the nut is positioned on the back side of the support plate, the middle part of the support plate is provided with female thread, the female thread is in threaded connection with the male thread of the screw rod, and the front end of the screw rod is propped against the outer side of the paired wheel. The contact area of the clamp plate, the filling plate and the paired wheel is large, the stress force on the paired wheel is balance, the paired wheel can not be damaged, the production cost is saved, the disassembly of the paired wheel is time and labor saving, and the utility model has obvious economic benefit and social benefit.

Description

Pump is to the wheel drawbench

Technical field:

The utility model is the device of dismounting pump, and particularly a kind of pump is to the wheel drawbench.

Background technology:

Existing is that three melons or two melon formulas are to the wheel pulley extractor to the wheel stripping attachment, when removing pump to wheel, the front end of three melons or two melons is suspended on the back transverse plane of taking turns, contact area is little, and is stressed big, three melons or two melons often occur and the problem of splitting is pulled out in the wheel contact position, cause wheel is damaged, increase increases production cost to the consumption of wheel, and not laborsaving.

Summary of the invention:

The purpose of this utility model be a kind of pump of design to the wheel drawbench, make its at the dismounting pump to when wheel, and the wheel large tracts of land contact, make the wheel stress equalization, can not occur being pulled out the problem of splitting to taking turns the contact position.

The purpose of this utility model is achieved in that by pump axle, clamp, wheel, support plate, leading screw, nut, screw rod, filling block is formed, the pump axle is installed on the wheel, draw-in groove is arranged on the clamp, filling block is placed in the draw-in groove, clamp, filling block block wheel, screw front end is fixed on the clamp, screw rod passes support plate, male thread is arranged on the screw rod, attaching nut on the male thread, nut is in the rear side of support plate, and box thread is arranged in the middle of the support plate, the male thread of box thread and leading screw screws, and the leading screw front end withstands the wheel outside.

The beneficial effects of the utility model are: clamp, filling block and long-pending big to wheel tread, make the wheel stress equalization, and can not damage wheel, can save production cost, it is time saving and energy saving to taking turns to dismantle, and has remarkable economic efficiency and social benefit.

Description of drawings:

Accompanying drawing 1 is the installation diagram of the utility model embodiment.

Accompanying drawing 2 is end view drawings of part 2 in the accompanying drawing 1.

Accompanying drawing 3 is end view drawings of part 8 in the accompanying drawing 1

The specific embodiment:

Below in conjunction with accompanying drawing the utility model embodiment is described.

As seen from the figure, embodiment of the present utility model by pump axle 1, clamp 2, to take turns 3, support plate 4, leading screw 5, nut 6, screw rod 7, filling block 8 form, pump axle 1 is installed in taking turns on 3, draw-in groove 9 is arranged on the clamp 2, filling block 8 is placed in 9 li of draw-in grooves, clamp 2, filling block 8 block taking turns 3, screw rod 7 front ends are fixed on the clamp 2, screw rod 7 passes support plate 4, on the screw rod 7 male thread is arranged, and the attaching nut 6 on the male thread, nut 6 is in the rear side of support plate 4, in the middle of the support plate 4 box thread is arranged, the male thread of box thread and leading screw 5 screws, and leading screw 5 front ends withstand taking turns 3 outsides.

Drawing is to taking turns 3 o'clock, and rotating threaded shaft 5 makes to produce the axial force of detachment machine pump shaft to taking turns 3, thereby pulls out taking turns 3.After limited Bit Track groove between draw-in groove 9 and the filling block 8, filling block 8 were placed in 9 li of draw-in grooves, filling block 8 can not move forward and backward.
