Description

A kind of processing method of eccentric shaft part

Technical field

The invention belongs to metalwork manufacture field, especially, the processing method of the eccentric shaft part being directed to.

Background technology

, it is known that eccentric part, there is two center lines on its appearance structure, and the two center lines are parallel to each other without weight Close, wherein common eccentric part is generally axle class formation part.

Eccentric shaft, as its name, its center is not at the center of axis.General axial workpiece, can only band Start building part rotation.And eccentric shaft, rotation can be not only transmitted, while revolution can also be transmitted.Conventional eccentric shaft is generally by inclined Heart hole is connected with electric machine rotational axis, in electric motor starting, does cam motion, therefore be widely used on automobile, engine, pump Etc..

But, exactly because also this structure type of eccentric shaft so that its processing is got up also relative to general axle class zero Part is difficult.But because it is used extensively, and function is important, also cause that industry develops various processing methods to add it Work.

For example, it is common, grab chuck using scroll chuck or four and clamp raw material, then carrying out cutting using lathe adds Work.Specifically, it first not being that eccentric part Excircle machining is good in part then by calculating, can add appropriate size Pad, carry out the processing of eccentric part.

This processing method, then during being embodied, with claimed below:

1st, the skilled worker being processed is required higher, it is desirable to have more processing experience;

2nd, measurer is repeatedly needed to use, the Working position of horizontal and vertical directions is corrected;

In this way, it is higher also to allow for the eccentric shaft part precision that it processes, but likewise, processing efficiency is just more low.And In actually used, some eccentric shaft parts, the machining accuracy that it simultaneously need not be too high is on the contrary to need processing higher to imitate Rate, so as to reduce its production cost.

Therefore, it is necessory to of the prior art to overcome to develop a kind of processing method of new eccentric shaft part Defect.

The content of the invention

It is an object of the invention to provide a kind of processing method of eccentric shaft part, its is simple to operate, and processing efficiency is relative It is higher;The crudy of its eccentric shaft part for processing, high yield rate are also ensured simultaneously.

To achieve these goals, the technical solution adopted by the present invention is as follows:

A kind of processing method of eccentric shaft part, it uses a chuck for clamping the raw pieces of workpiece to be processed, wherein institute State and be provided with the claw of chuck an excentric sleeve, wherein can be from after the clamping force of chuck jaws that is subject to of the excentric sleeve It is dynamic to tighten up and clamp the workpiece to be processed housed in it, and the bias that top top biases at the other end of the workpiece to be processed Hole.The cylindrical center line of the wherein described excentric sleeve center line cylindrical with the workpiece to be processed small end is coaxial, its endoporus The center line cylindrical center line cylindrical with the big end of the workpiece to be processed is coaxial, and then workpiece to be processed described in turnery processing is inclined The heart is cylindrical to preliminary dimension.

Further, in different embodiments, wherein being provided with groove in the axial direction on the eccentric bushing is cylindrical, it is used for Make the excentric sleeve by automatic tightening after the clamping force of chuck jaws and clamp workpiece.

Further, in different embodiments, wherein the size of the groove on the eccentric bushing is cylindrical for 0.5 ~ 3mm。

Further, in different embodiments, wherein the size of the groove on the eccentric bushing is cylindrical for 1.5 ~ 2mm。

Further, in different embodiments, wherein being additionally provided with the endoporus of the excentric sleeve from centering swelling Set, the workpiece to be processed passes through described from endoporus of the centering expansion sleeve swelling in the excentric sleeve, then will be described inclined Spindle sleeve is clamped in the chuck.

Further, in different embodiments, wherein the chuck includes that three-jaw self-centering chuck or four paws are made by oneself One kind in heart chuck.

Further, in different embodiments, wherein when being processed to the workpiece to be processed, its elder generation is from rough turn Processing starts, and is then carrying out finishing processing.

Further, in different embodiments, wherein it is described it is rough turn during, its allowance be 0.5 ~ 2mm.

Further, in different embodiments, wherein when being processed to the workpiece to be processed, its elder generation is auxiliary from its Positioning reference plane is helped to start processing.

A kind of processing method of the eccentric shaft part provided relative to prior art, the present invention, it uses the fixture of innovation Combine to carry out clamping when eccentric shaft part is processed so that its subsequent machining operations is relatively simple, although machining accuracy is relative It is relatively low, but its crudy reliability, high yield rate, the processing efficiency of the eccentric shaft part not high for required precision is improve, Make it have preferable production and application prospect.

Specific embodiment

Below with reference to embodiment, a kind of technical scheme of the processing method of eccentric shaft part of the present invention is made into The detailed description of one step.

An embodiment of the invention provides a kind of processing method of eccentric shaft part, and it uses the chuck to be used for The raw pieces of workpiece to be processed are clamped, wherein an excentric sleeve is provided with the claw of the chuck, wherein the eccentric shaft Automatic tightening is understood after the clamping force of the chuck jaws that set is subject to and the workpiece to be processed housed in its is clamped, and described to be processed The eccentric orfice of top top biasing at the other end of workpiece.

Further, the clamping for the excentric sleeve to workpiece to be processed in the inner, the invention provides two kinds of folders Hold mode.

Mode one:

Groove is set in the axial direction on wherein described eccentric bushing is cylindrical, for making the excentric sleeve be pressed from both sides by chuck jaws Automatic tightening and workpiece is clamped after clamp force.The size of wherein described groove is 0.5 ~ 3mm, it is preferred that be 1.5 ~ 2mm.

Mode two:

It is additionally provided with the endoporus of wherein described excentric sleeve from centering expansion sleeve, the workpiece to be processed is by described from centering Then be clamped in the excentric sleeve in the chuck by expansion sleeve swelling in the endoporus of the excentric sleeve.

After completing clamping, wherein the cylindrical center line of the excentric sleeve center cylindrical with the workpiece to be processed small end Line is coaxial, and the center line of its endoporus cylindrical center line cylindrical with the big end of the workpiece to be processed is coaxial, then turnery processing institute State the eccentric excircle of workpiece to be processed to preliminary dimension.
