Summary of the invention
It is an object of the invention to provide in place of making up the deficiencies in the prior art, a kind of molding simplicity, precision be higher, surface
The planetary cycloid reducer pin wheel housing internal tooth processing method that hardness is higher, the service life is longer.
The purpose of the present invention is what is realized by following technological means:
A kind of planetary cycloid reducer pin wheel housing internal tooth processing method, it is characterised in that:Include the following steps:
(1) prepares the pin wheel housing green body what a has been circularized, and processes half that a circle is uniformly distributed using gear shaping method
Circle, it is unilateral to stay 0.2-0.3mm machining allowance;
(2) uses internal tooth method for grinding, is ground semicircle orifice, unilateral to stay 0.01-0.02mm machining allowance;
(3) carries out ultrasound-enhanced semicircle internal surface of hole using person of outstanding talent gram energy cutting tool special for processing, strengthens-half essence by force using thick
The mode that change-essence is strengthened reaches size requirement.
Moreover, step (1) it is described the specific steps are:Pin wheel housing green body is installed on gear shaper workbench, numerical control is write and adds
Engineering sequence processes the semicircle orifice that a circle is uniformly distributed, unilateral to stay 0.2-0.3mm machining allowance.
Moreover, step (2) it is described the specific steps are:(1) semi-finished product that step is processed are mounted on internal tooth gear grinding machines work
Make on platform, the relative position of each semicircle orifice 1 of centering, write nc program, is ground semicircle orifice, it is unilateral to stay 0.01-0.02mm
Machining allowance.
Moreover, step (3) it is described the specific steps are:(2) semi-finished product that step is processed, being mounted on can knife with person of outstanding talent gram
On the workbench of the vertical machining centre of tool, nc program is write in the relative position of each semicircle orifice 1 of centering, ultrasound-enhanced
Fifty-fifty circular hole interior surface reaches size requirement in such a way that the smart reinforcing-essence of thick reinforcing-half is strengthened.
The advantages and positive effects of the present invention are:
The present invention relates to the manufacture processing methods of planetary cycloid reducer pin wheel housing, solve planetary cycloid reducer needle tooth
The deficiency of shell internal tooth processing method has invented the planetary cycloid reducer that a kind of molding is easy, precision is higher, the service life is longer
Pin wheel housing internal tooth processing method.
The invention belongs to technical field of mechanical processing, this method the specific steps are:What a prepares first to have circularized
Pin wheel housing green body, the semicircle that a circle is uniformly distributed is processed using gear shaping method, it is unilateral to stay 0.2-0.3mm machining allowance;Its
It is secondary to use internal tooth method for grinding, it is ground semicircle orifice, it is unilateral to stay 0.01-0.02mm machining allowance;Finally add using bold and unconstrained gram energy is dedicated
Work cutter carries out ultrasound-enhanced semicircle internal surface of hole, in such a way that the smart reinforcing-essence of thick reinforcing-half is strengthened, reaches size and wants
It asks.The present invention provides a kind of moldings, and three-step approach internal tooth easy, that precision is higher, surface hardness is higher, the service life is longer adds
Work method.This method specificity is strong, is especially suitable for installing a series of radiuses of gear pin in processing planetary cycloid reducer shell
Compared with the hole that small, draw ratio is big, precision is higher, shape is semicircle.
Specific embodiment
With reference to the accompanying drawing in detail narration the embodiment of the present invention, it should be noted that the present embodiment be it is narrative, no
It is restrictive, this does not limit the scope of protection of the present invention.
A kind of planetary cycloid reducer pin wheel housing internal tooth processing method, includes the following steps:
(1) prepares the pin wheel housing green body (as shown in Figure 1) what a has been circularized, and installs on gear shaper workbench, writes
Nc program processes the semicircle orifice 1 (as shown in Figure 2) that a circle is uniformly distributed using gear shaping method, unilateral to stay 0.2-
0.3mm machining allowance, it is high in machining efficiency.
(2) (1) semi-finished product that processes step are mounted on internal tooth gear grinding machine working platform, using internal tooth method for grinding,
Nc program is write in the relative position of each semicircle orifice 1 (as shown in Figure 2) of centering, is ground semicircle orifice 1, unilateral to stay 0.01-
0.02mm machining allowance, machining accuracy are easily guaranteed that.
(3) (2) semi-finished product that processes step are mounted on the workbench of the vertical machining centre with person of outstanding talent gram energy cutter
On, nc program is write in the relative position of each semicircle orifice 1 (as shown in Figure 2) of centering, can specific processed cutter using person of outstanding talent gram
Tool, carries out ultrasound-enhanced semicircle internal surface of hole, in such a way that the smart reinforcing-essence of thick reinforcing-half is strengthened, reaches size requirement, table
Surface hardness increases substantially.
