Description
Technical field
The invention belongs to the technical fields of positioning tool in being machined, and in particular to a kind of vertical processing planet of spline positioning
The clamping device and processing technology of frame.
Background technique
Planet carrier processes planetary gear axis hole, and there are position degree and verticality requirement in hole relative to spline reference circle.Present technique
Planet carrier outer circle is clamped using three-jaw, or utilizes outer circle or Internal hole positioning using tooling, using vertical machining centre equipment, is carried out
Planet wheel spindle hole machined.Planet carrier outer circle is clamped using three-jaw, or utilizes outer circle or Internal hole positioning using tooling, is by spline point
Degree circle positioning is converted to outer circle or inner hole as machining benchmark.Machining benchmark and use benchmark disunity in this way, in conversion process
In, due to factors such as mismachining tolerances, causes product finally and not can guarantee hole relative to spline reference circle Geometrical Tolerance Principle.Product
It causes planet carrier revolution to turn round decentraction with sun gear in use, causes noise, abnormal sound and other issues.Fig. 1 illustrates one kind
Existing planet carrier positioning device.
Summary of the invention
It is an object of the invention to: above-mentioned deficiency in the prior art is solved, a kind of vertical processing planet of spline positioning is provided
The clamping device and processing technology of frame.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of vertical processing planet carrier of spline positioning is provided
Clamping device, including ringfeder, ringfeder pressing plate and base assembly, the base assembly passes through the centre bore and planet carrier of planet carrier
It is mounted on the base assembly；The ringfeder is sleeved on the base assembly and the outer round surface of the ringfeder has and row
The external splines of the internal spline cooperation of carrier centre bore, its internal diameter gradually subtracts during the bottom of the ringfeder extends to top
Small, the suit pressing plate is also sleeved on the base assembly and is fitted on the ringfeder.
Further, the base assembly runs through the centre bore of planet carrier and extends to outside the centre bore of planet carrier, described
Pressing plate is set at the top of base assembly, the platen cover is set to the top of planet carrier；Be further sleeved on the base assembly by
The clamp nut that the pressing plate compresses.
Further, the ringfeder has first and second, the second position in first top and
Described second the ringfeder pressing plate is sleeved in；First bottom to top extend during described first
Internal diameter be gradually reduced and first top and second junction are provided with and are used to support the ringfeder pressure
The supporting table of plate.
The present invention also provides a kind of processing technologys of planet carrier, comprising the following steps:
S1 casts planet carrier blank；
S2, small end and big end to planet carrier blank are processed by numerical-control horizontal lathe；
S3 processes internal spline by center of the gear shapping machine to blank；
S4, the clamping device for positioning vertical processing planet carrier by spline are vertical to passing through again after the carry out spline positioning of blank
Formula Cutter Body Processing with Machining Center planetary gear axis hole and open a grade end face.
By adopting the above-described technical solution, the beneficial effects of the present invention are:
The present invention utilize taper spreading principle, due to first of ringfeder its bottom to top extend during internal diameter by
It is decrescence small, therefore the inner wall of ringfeder has certain taper, therefore ringfeder taper inner is when spindle taper moves up and down, ringfeder
The synchronous spreading of outer circle or diminution.Ringfeder outer circle is designed to spline joined together by planet carrier by the clamping device, under ringfeder pressing plate
When pressure, ringfeder spline outer circle swell therewith tightly cooperates with planet carrier internal spline key side, reaches the effect of planet carrier spline positioning
Then fruit reprocesses star axle hole, to ensure that the hole of processing and the relative position of planet carrier internal spline.
Using ringfeder, using spline key side positioning, is exactly directly processed using the positioning of spline reference circle, in this way can
Complete to guarantee position degree and verticality, position degree is stablized within 0.03 in actual production, and verticality is stablized 0.02 or so, together
When can complete planetary gear axis hole in one step and open the processing of grade face, save process time, improve efficiency.
