Abstract
The utility model relates to an omnipotent top ware that draws, mainly used machinery trade middle shafting spare part's dismantlement, installation. The flange disc type code pulling disc is mainly characterized in that a lead screw, a tip cone and a pull rod are arranged on the flange disc type code pulling disc, and mounting parts are disassembled by utilizing the jacking force of the lead screw and the pulling force of the pull rod. The pulling and jacking device has the characteristics of loose and flexible use conditions, strong functions and stable operation.
Description
The utility model relates to a kind of pulling/pushing device.
At present, in mechanical industry maintenance, the extracting tool of shafting components is of a great variety, yet their function is all comparatively single, service condition is relatively harsh, and flexibility is relatively poor, and what have in use needs many aids or supplementary means, be not easy to field operation, secondly rely on present instrument also to have sizable difficulty in the shafting components unloading process of some large equipments.The 3rd, to producing damage to it in the existing instrument unloading process of the higher parts of some required precisions.
It is a kind of for convenience detach that the purpose of this utility model is to provide, and installation shaft is the instrument of parts---omnipotent pulling/pushing device.
The technical solution of the utility model is: it is by drawing code-disc, screw component, pull bar, addendum cone and the auxiliary code-disc that draws are formed, and drawing code-disc is the flange plate type structure, and the center is a screw, be symmetrically arranged with a plurality of radially waist through hole on the dish of garden, screw component is connected with drawing code-disc by center screw, and an end of screw mandrel connects addendum cone, and pull bar is installed in and draws in the code-disc waist through hole.
When axle is before parts are installed in axle and go up partially or partially to adjust by the length that reduces or increase pull bar and screw mandrel during the back, aid and raising have been reduced to neutrality.When axle is that parts are non-circular or diameter is bigger, or the piston type counterpart can utilize some hole on it to be connected with screw mandrel formula pull bar to dismantle.
For the functional configuration that increases pulling/pushing device has the auxiliary code-disc that draws, when the parts of pull bar are installed in dismounting bearing type component or the higher parts of required precision and inconvenience, can will assist the back of drawing code-disc to be installed in to wait to tear open parts, make by pull bar and auxiliaryly draw code-disc to be connected to dismantle parts with pulling/pushing device.

The utility model is described in further detail below in conjunction with accompanying drawing
As Fig. 1, shown in Figure 2, the utility model draws code-disc 2 by screw component 1, addendum cone 4, and pull bar 3,5 and the auxiliary code-disc (Fig. 8, shown in Figure 9) that draws are formed.
Drawing code-disc is the flange plate type structure, is screw at the center of drawing code-disc, and screw component is connected with drawing code-disc by screw thread, draw code-disc around be symmetrical arranged four waist through hole, pull bar is by waist through hole, of pull bar hangs on by nut and draws on the code-disc.Screw component in use can adopt suitable length according to the use occasion of pulling/pushing device, and addendum cone can adopt interior addendum cone and outer addendum cone according to the difference of purposes.As shown in Figure 4, addendum cone of the present utility model is outer addendum cone.As shown in Figure 5, interior addendum cone of the present utility model.Pull bar of the present utility model as shown in Figure 6 is a screw mandrel formula pull bar.As shown in Figure 7, pull bar of the present utility model is the drag hook type pull bar.
It is not too big that the drag hook type pull bar is used for pulling force, the occasion that the parts required precision is not high, and screw mandrel formula pull bar is applicable to that parts with holes or screwed hole are dismantled on the part, its pulling force can damage parts greatly and not.
After installing pulling/pushing device by the characteristics of parts, block with spanner then and draw code-disc, turn screw mandrel, can realize the dismounting or the installment work of parts smoothly.
The auxiliary code-disc that draws (as Fig. 8, Fig. 9) is mainly used in that inconvenient pull bar uses or to the demanding occasion of dismounting assembly precision.
Claims (5)
1 one kinds of omnipotent pulling/pushing devices, it is characterized in that: by drawing code-disc, screw mandrel, screw component, addendum cone and the auxiliary code-disc that draws are formed, drawing code-disc is flange-type structure, the center is a screw, is symmetrical arranged many radially waist through hole on the dish of garden, and screw component is connected with drawing code-disc by screw, screw mandrel one end connects addendum cone, and pull bar is installed in and draws in the code-disc waist through hole.
