Description
Technical field
The invention belongs to planetary carrier manufacture fields, and in particular to a kind of two-way process tool for guaranteeing concentricity.
Background technique
Gear Planet Transmission includes sun gear, planetary gear, planetary carrier assembly, planet wheel spindle, bearing etc..Planetary carrier is total
At the important components of Gear Planet Transmission are belonged to (see Fig. 1), it is made of main frame, sub-frame, positioning pin and fastening bolt.Planet row
Frame assembly is a kind of weak rigid hollow type structure, and two bearing mounting surfaces are design basis, and 4 planetary gear axis holes are tested want
Element.Since precision is higher, while two bearing mounting surfaces are limited to because of structure, cannot once be completed, it is necessary to turning process is used,
Planet wheel spindle mounting surface must use boring milling process, and the processing of design basis and element to be measured needs extension set bed to carry out, can not
Direct connection is generated, design basis and technological datum can not accomplish perfect unification, therefore produce correct error and inspection
Error etc. is surveyed, the accuracy of form and position (position degree, the depth of parallelism) of element to be measured guarantees extremely difficult.
Summary of the invention
The present invention provides a kind of two-way process tool for guaranteeing concentricity, and technical problems to be solved are: solving planet
Arrange the overproof problem of the geometric tolerance after frame assembly is processed.
In order to solve the above technical problems, the present invention provides a kind of two-way process tool for guaranteeing concentricity, feature
It is: including blind rivet 1, knife handle 2, knife bar 3, cutter head and blade；Blind rivet 1, knife handle 2, knife bar 3 are fixedly connected sequentially, two cutter heads
It is installed in parallel on knife bar 3；A blade, contrary and two points of a knife the cutting of two blades are fixed on each cutter head
On the contrary, point of a knife distance forms two-way process tool greater than the depth for being processed hole, underlying blade processes top at angle
Hole, the hole for the blade processing lower section being located above；Two cutter heads are identical relative to the overhang of knife bar and to avoid interference with planet
The shaft shoulder on frame；When processing, the hole of underlying blade processing top is first passed through, cutter returns to knife bar integral central to frame
Frame integral central is moved to coincidence, and then knife bar moves downward, and passes through stomidium under frame, and Tool advance makes knife bar center line and frame
Frame integral central line is overlapped, and by the hole for the blade processing lower section being located above, guarantees the concentricity in two holes up and down.
The utility model has the advantages that the present invention provides a kind of planet row by using vertical complex milling machine tool or vertical machining centre
The cutter of the two-way processing of frame, design basis (bearing mounting surface) the cutter of clamped one time for realizing planetary carrier add
Work, design basis and element to be measured (planetary gear axis hole) are processed with clamped one time tool changing twice, make the axis of planetary carrier assembly
It holds during mounting surface adds with planetary gear axis hole machine and directly contacts, design basis and technological datum is made to accomplish perfect system
One.Geometric tolerance after solving the problems, such as the processing of planetary carrier assembly is overproof.Structure of the invention is novel, height easy to operate
Effect provides a kind of completely new solution route for the bearing hole of planetary carrier and the mechanical processing technique of planetary gear axis hole, adds
Working medium amount is reliable and stable.

Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, a specific embodiment of the invention is made into one below
Step detailed description.
A kind of two-way process tool guaranteeing concentricity proposed by the present invention, including blind rivet 1, knife handle 2, knife bar 3, cutter head I
4, cutter head II 5, blade I 6, blade II 7, adjustable nut I 8, adjustable nut II 11, clamp nut I 10, clamp nut II 9, balance
Block 12；Adjustable nut, clamp nut, the connecting mode of balance weight are identical as universal numerical control cutter,
Blind rivet 1, knife handle 2, knife bar 3 are fixedly connected sequentially, and cutter head I 4, cutter head II 5 are installed in parallel on knife bar 3, each knife
Head is connect by adjustable nut and clamp nut with knife bar；
Blade is fixed on cutter head, contrary and two points of a knife the cutting angle of two blades is on the contrary, point of a knife distance is big
In the depth for being processed hole, two-way process tool, the hole of underlying blade processing top are formed, the blade being located above adds
Hole below work.Two cutter heads are identical relative to the overhang of knife bar and are greater than 22mm, avoid interference with the shaft shoulder on planet carrier.
When work, by selecting vertical complex milling machine tool or vertical machining centre and numerical programming processing program, first lead to
The hole of underlying blade processing top is crossed, cutter returns to knife bar integral central and is moved to coincidence to frame entirety center,
Then knife bar moves downward, and passes through stomidium under frame, and Tool advance is overlapped knife bar center line with frame entirety center line, passes through
The hole for the blade processing lower section being located above, guarantees the concentricity in two holes up and down.
Blind rivet, knife handle, knife bar, cutter head assembly (contain blade/adjustable nut/clamp nut), balance weight connecting mode with
Universal numerical control cutter is identical, and increased another 1 cutter head assembly is installed in parallel in the top of original cutter head, insert orientation (cutting and
Feed) on the contrary, forming two-way process tool.The overhang of two cutter heads is greater than 22mm.
When work, by drawing by the size of two blades of cutter, it is qualified to be adjusted using tool setting gauge, is packed into lathe,
It is processed by planetary carrier assembly drawing requirement.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
