Description

Flange internal spline inner hole taper machining device

Technical Field

The utility model relates to the field of flange machining, in particular to a device for machining inner hole taper of a flange inner spline.

Background

Because the internal spline diameter of work piece is not of uniform size, before the internal spline tapering processing, need sort the internal diameter to the work piece earlier, to the internal spline diameter of difference, need adopt the tapering mould of different external diameters just can realize accurate deformation volume control, otherwise the internal diameter is big can not produce the tapering, and the little tapering deformation of internal diameter exceeds the requirement, and the deformation size is unstable, has increased manpower and materials cost simultaneously.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a flange internal spline inner hole taper machining device with precise action.

The technical scheme of the utility model is as follows: the utility model provides a flange internal spline hole tapering processingequipment, set up on the hydraulic press, a spline on the neck inner wall for preparing the flange, the base of flange is fixed on the hydraulic press workstation, this processingequipment includes the inner cone of fixed mounting pressure head on the hydraulic press, fix the outer cone on the hydraulic press workstation through spacing subassembly, the external diameter of outer cone is the same with the size of spline, the internal diameter of outer cone and the external diameter phase-match of inner cone, outer cone passes through the spring ring by the trisection cone and links into an integrated structure, the cover is equipped with reset spring on the top conical surface that is located the outer cone of inner cone.

According to a further technical scheme, the limiting assembly comprises a limiting stop block fixed on a hydraulic machine workbench through a bolt.

According to a further technical scheme, spring rings are arranged at the top and the bottom of the outer cone body.

The utility model has the beneficial effects that:

the utility model applies pressure to the inner cone through the hydraulic machine, thereby ensuring the downward pressure of the inner cone to be constant, the outward expansion force of the outer cone to the inner wall of the spline is also in a constant state, and the change of the taper size is relatively constant. Compared with the prior art, the utility model saves the procedure of inner diameter sorting and can directly manufacture the required conicity value. The operation cost is low, the structure is simple, the implementation is convenient, and the benefit is improved.

Drawings

FIG. 1 is a schematic structural view of the present invention,

the hydraulic press comprises a hydraulic press workbench 1, a hydraulic press upper pressure head 2, a flange 3, a neck 31, a neck 32, a base 4, an inner cone 5, an outer cone 6, a spring ring 7, a reset spring 8, a limiting assembly 81, a limiting stop 82 and a bolt.

Detailed Description

The utility model will be further illustrated and understood by the following non-limiting examples.

As shown in fig. 1, the utility model provides a device for processing the taper of an inner hole of a flange internal spline, which is arranged on a hydraulic machine and used for preparing a spline on the inner wall of a neck 31 of a flange 3, wherein a base 32 of the flange 3 is fixed on a workbench 1 of the hydraulic machine, the processing device comprises an inner cone 4 fixedly arranged on a pressure head 2 of the hydraulic machine and an outer cone 5 fixed on the workbench 1 of the hydraulic machine through a limiting component 8, and the limiting component 8 comprises a limiting stop 81 fixed on the workbench 1 of the hydraulic machine through a bolt 82.

The outer cone 5 has the same outer diameter size as the spline, the outer cone 5 has the inner diameter size matched with the outer diameter of the inner cone 4, the outer cone 5 is connected into an integral structure by trisection cones through a top spring ring 6 and a bottom spring ring 6, and a return spring 7 is sleeved on the conical surface of the inner cone 4 above the outer cone 5.

When the hydraulic press works, a worker presets the pressing pressure of the upper pressing head 2 of the hydraulic press, the upper pressing head acts on the inner cone 4, the downward pressure of the inner cone 4 is constant, and therefore the outward expansion force of the outer cone on the inner wall of the spline is also in a constant state, and the change of the taper size is relatively constant.

The pressure head stops pressing down and returns in time, the inner cone 4 is drawn out under the action of the strong spring, the outer cone 5 retracts under the action of the spring ring 6 and is separated from the neck 31 of the flange 3, and therefore splines on the inner wall of the neck 31 achieve the required taper.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
