Abstract
The invention discloses thin-walled female splined shafts to draw tooth technique, it is characterised in that steps are as follows: S1, blanking: round steel being selected to carry out blanking as material；It is S2, rough turn: material is carried out it is rough turn, and by smart car size to the inner hole of rough turn material, outer circle, each reserved 3mm surplus of length；S3, modifier treatment: the hardness of the material after will be rough turn is maintained at 300-350HBW；S4, smart car: material is machined to specified size by smart car figure, specifically, the positioning surface of material after modifier treatment is filled in into broaching machine and is adjacent to, then material is clamped using Pneumatic hydraulic, then takes out broaching tool and fill among the axis hole of material, restarts the travel switch of broaching machine, process broaching tool to the axis hole wall of material, to the end of stroke, the internal spline of material is just completed the process, and materiel machining is at specified thin-walled female splined shaft.The present invention processes internal spline by broaching tool, reduces machining working hour, improves processing quality and efficiency.
Description
Technical field
The present invention relates to the technical fields of female splined shaft processing, and in particular to thin-walled female splined shaft draws tooth technique.
Background technique
Currently, domestic thin-walled female splined shaft uses gear shaping technique mostly to process internal spline, drawback is that work is imitated
Rate is low, labor intensity of workers is big, unstable quality, required precision are low, and cutter loss is big, is only suitable for small lot processing.
Summary of the invention
In view of the deficiency of background technique, the present invention provides the thin-walled internal splines that can effectively improve processing efficiency and quality
Axis draws tooth technique.
For this purpose, the present invention provides the following technical scheme that
Thin-walled female splined shaft draws tooth technique, and steps are as follows:
S1, blanking: round steel is selected to carry out blanking as material；
It is S2, rough turn: material to be carried out rough turn and each reserved to the inner hole of rough turn material, outer circle, length by smart car size
3mm surplus；
S3, modifier treatment: the hardness of the material after will be rough turn is maintained at 300-350HBW；
S4, smart car: material is machined to specified size by smart car figure, specifically, by the positioning of the material after modifier treatment
Face is filled in broaching machine and is adjacent to, and then clamps material using Pneumatic hydraulic, then takes out broaching tool and fill among the axis hole of material, then open
The travel switch of dynamic broaching machine, processes broaching tool to the axis hole wall of material, to the end of stroke, the internal spline of material is just processed
At materiel machining is at specified thin-walled female splined shaft.
When smart car, if material tool is there are two internal spline, two internal spline same cores are coaxial.
The shape of the broaching tool and the shape of the internal spline of material to be processed match.
Compared with the prior art, the invention has the beneficial effects that: the side that the present invention uses broaching tool to broach on broaching machine
Formula processes internal spline, can effectively improve production efficiency, reduces machining working hour, mitigate labor intensity of workers, improve part matter
Amount, when high-volume is processed, advantage can more embody.Since the performance of the female splined shaft processed is effectively promoted with quality,
It can be used for the devices such as aircraft, automobile, tractor, machine-tool industry, agricultural machinery and common mechanical transmission.
Detailed description of the invention
The present invention has following attached drawing:
Fig. 1 is the schematic diagram that broaching tool of the invention is processed.
Specific embodiment
Thin-walled female splined shaft of the invention draws tooth technique, and steps are as follows:
S1, blanking: round steel is selected to carry out blanking as material, wherein round steel uses 42CrMo, φ 95*228；
It is S2, rough turn: material to be carried out rough turn and each reserved to the inner hole of rough turn material, outer circle, length by smart car size
3mm surplus；
S3, modifier treatment: the hardness of the material after will be rough turn is maintained at 300-350HBW；
S4, smart car: material is machined to specified size by smart car figure, specifically, by the positioning of the material after modifier treatment
Face 1 is filled in broaching machine and is adjacent to, and then clamps material using Pneumatic hydraulic, then takes out broaching tool 3 and fill among the axis hole of material, then
The travel switch for starting broaching machine, processes broaching tool to the axis hole wall of material, and to the end of stroke, the internal spline 2 of material just adds
Work is completed, and materiel machining is at specified thin-walled female splined shaft.Wherein, the schematic diagram of broaching tool processing materials is as shown in Figure 1, arrow side
To for start stroke directions.
In the present embodiment, when smart car, for material tool there are two internal spline 2, two 2 same cores of internal spline are coaxial.Of the invention
Processing technology can guarantee that two 2 same cores of internal spline are coaxial, effectively increase the processing quality of product, and not need to increase postorder
Go flash removed process, be effectively reduced labor intensity of workers, improve production efficiency.
In the present embodiment, in order to obtain accurately processing effect, broaching tool is customized, and the shape of broaching tool with it is to be processed
The shape of the internal spline 2 of material matches.
To sum up, the present invention processes internal spline 2 in such a way that broaching tool 3 is broached on broaching machine, can effectively improve production effect
Rate reduces machining working hour, mitigates labor intensity of workers, improves part quality, and when high-volume is processed, advantage can more embody.
