Abstract

The utility model relates to a novel assembly shaft, which can effectively solve the problems that the existing shaft body and a wheel sleeve are difficult to assemble and disassemble, and the existing shaft body has poor use effect and high cost. The technical scheme for solving the problems is as follows: the novel assembly shaft comprises a shaft body, wherein the end part of the shaft body is provided with an expansion section head, and a tapered screw is arranged in a mounting hole at the center of the expansion section head; and a wheel sleeve is arranged on the expansion section head. The utility model is unique in structure and convenient to use, has good effect, and is an innovation of the shaft body.

Description

A kind of novel assembled shaft

One, technical field

The utility model relates to a kind of novel assembled shaft.

Two, background technique

In the past on axis body during workpiece such as assembly wheel cover class, generally all be to adopt heating expansion sleeve workpiece or cooling axis body to shrink the axis body assembling, and when dismounting trouble, mostly adopt and pull out instruments such as axis body device, press machine or jack and finish, What is more, directly pounds with hammer and dismantle, sometimes pull out workpiece bad and also can not pull out the wheel cover, have only the wheel cover is carried out the destructiveness dismounting, time-consuming, influence axis body and overlap original technology capability.

Generally the wheel sleeve workpiece is assemblied on the axis body abroad now through opening tapered sleeve and being used of wheel sleeve workpiece, reinforce use with three to four bolts through tapered sleeve and half tension on the wheel, with two bolts handle wheel is extruded from the opening tapered sleeve during dismounting, strut tapered sleeve dismounting wheel cover, this structure convenient disassembly, but the wheel cover must have certain neutral with being connected of axis body, and tapered sleeve and wheel cover processed complex, the material use amount is big, the cost height.

Three, model utility content

At above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of novel assembled shaft, can effectively solve existing axis body and take turns the problem that cover assembles, dismounting bothers, using effect is bad and cost is high, and the technological scheme of its solution is, comprise axis body, there is the expanding petal head axis body end, in the mounting hole at expanding petal head center cone screw is housed, and the wheel cover is housed on the expanding petal head, the utility model structure uniqueness, easy to use, effective is the innovation on the axis body.

Four, description of drawings

Fig. 1 is a sectional front view of the present utility model.

Fig. 2 is the right elevation of the utility model axis body.

Fig. 3 is another an embodiment's of the present utility model sectional front view.

Five, embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Provided by Fig. 1-Fig. 3, the utility model comprises axis body, and there is expanding petal head 2 axis body 1 end, in the mounting hole 3 at expanding petal head 2 centers cone screw 4 is housed, and wheel cover 9 is housed on the expanding petal head 2.

In order to guarantee using effect, said expanding petal head 2 is for radially waiting cylindrical body that is cut into four or six lobe bodies.

Said cone screw 4 is made of taper and the nut 5 that is connected as a single entity, on the nut 5 through hole is arranged, anti-back screw 6 is housed in the through hole, in the anti-back screw hole 7 of anti-back screw 6 spinnings on expanding petal head 2, nut 5 is square or Hexagon, and there is interior hexagonal shaped pilot hole 8 at its outer side surface center.

The said cone screw 4 outer taper sheaths 10 that are set with, taper sheath 10 is for waiting conical sleeve that is cut into four or six lobe bodies.

Use condition of the present utility model is, the expanding petal head is made in the end of axis body 1, during assembling, because there is expanding petal head 2 the axis body end, wheel cover 9 is easy to be sleeved on the axis body 1, cone screw 4 screws in the mounting hole 3 at expanding petal head 2 centers, it is big that expanding petal head 2 diameters become, and axis body 1 and wheel cover 9 are closely cooperated together, and anti-back screw 6 screws in the anti-back screw hole 7, prevent that cone screw 4 is from mounting hole 3 interior loosening skidding off, during dismounting, the anti-back screw 6 of dismantling screws out cone screw 4, expanding petal head 2 is loosening, easily takes away wheel cover 9.

The utility model structure uniqueness, easy to use, using effect good, is the innovation on the axis body, has remarkable economical and social benefit.
