Description
Technical field
The present invention relates to a kind of processing method, especially a kind of manufacturing method of split-type gear case body belongs to the Machining Technology field.
Background technology
At present, the gear-box that uses on the subway adopts split type casing usually, and adopts the bottom half method for processing to guarantee that the outside circle and the bottom half of driven gear have enough distances, guarantee the gear case body bottom thickness simultaneously.In process in the past; usually adopt the inboard of processing die joint, bearing saddle bore and bottom half when roughing; the method in processing die joint, bearing saddle bore and bottom half outside during fine finishining; but because the medial and lateral, bottom are benchmark with die joint, bearing saddle bore all; therefore regular meeting produces the overproof situation of bottom half thinnest part thickness; the method correction of the artificial polishing of thickness employing bigger than normal, thickness is less than normal then to cause scrapping of a whole set of casing.
Summary of the invention
The objective of the invention is to: at the problem that above-mentioned prior art exists, provide the processing method of the more rational split-type gear case body of a kind of processing technology, make its efficient higher.
Purpose of the present invention is achieved through the following technical solutions:
A kind of manufacturing method of split-type gear case body, described gear housing comprises die joint and the receiving space that is enclosed to form by its sidepiece and bottom, described die joint is provided with the locating hole that is used for another split-type gear case body zoarium, the curved setting in the cross section of described sidepiece, the cross section of described bottom linearly is provided with, and may further comprise the steps:
The sidepiece of a, the described gear case body of clamping is a benchmark centering casing center line with cabinets cavity size and bottom outside;
B, utilize the die joint of the described gear case body of boring and milling machine roughing;
C, be benchmark, the casing die joint placed downwards on the frock and fixing, utilize the further roughing bearing saddle bore of boring and milling machine with the die joint;
D, casing is lain against on the special tooling and clamp, with horizontal Machining centers fine finishining die joint;
E, be benchmark, do not change installation way, the workbench of rotation horizontal Machining centers, machining box bottom outside with the die joint after the fine finishining;
The locating hole of f, dependence die joint makes bearing saddle bore become a full circle gear-box zoarium, and casing is placed on the vertical machining centre, uses top jack-up, and centering casing center line also clamps precision machined bearing seat hole;
G, be benchmark with the bearing saddle bore after the fine finishining, casing is positioned over special tooling on the boring and milling machine, the main shaft of adjusting lathe is consistent with the axis of bearing saddle bore, the machining box bottom inside.
Other processing parts of described gear case body are interted and are processed in above-mentioned steps.For example: also comprise the observation window that utilizes the boring and milling machine working gear-box, the step of oil filler point behind the described step b.Also be included in the step of the screwed hole of processing oil gauge, drain oil and described bearing saddle bore end face on the vertical machining centre among the described step f.
Beneficial effect of the present invention is mainly reflected in:
1) working (machining) efficiency is higher, has reduced because the delivery date that artificial polishing brings prolongs and human and material resources are wasted in a large number;
2) yield rate of casing processing is higher.

The specific embodiment
The present invention has disclosed a kind of manufacturing method of split-type gear case body, what the method for machining box bottom outside was different when the inboard during with prior art roughing bottom the machining box, fine finishining is, method of the present invention is with other part of reprocessing casing after finishing as the die joint fine finishining of benchmark, especially the size of bottom half, outside circle and the bottom half of guaranteeing moving gear have enough distances, and guarantee the gear case body bottom thickness simultaneously.
In conjunction with the accompanying drawings, described gear case body 10 comprises die joint 1 and the receiving space that is enclosed to form by its sidepiece 6 and bottom 3, described die joint 1 is provided with the locating hole that is used for another casing zoarium, the roughly curved setting in the cross section of described sidepiece 6, the cross section of described bottom 3 roughly linearly are provided with.
Concrete steps of the present invention are as follows:
The sidepiece 6 of a, the described gear case body 10 of clamping is a benchmark centering casing center line with cabinets cavity size and bottom outside, utilizes the die joint 1 of the described gear case body of boring and milling machine TX611D roughing;
B, be benchmark, the casing die joint placed downwards on the frock and fixing, utilize the further roughing bearing saddle bore 2 of boring and milling machine TX611D with the die joint;
C, casing is lain against special tooling and clamp, with the locating hole on horizontal Machining centers fine finishining die joint 1 and the die joint;
D, be benchmark, do not change installation way, rotate the workbench of described horizontal Machining centers, machining box bottom outside 3 with the die joint after the fine finishining 1;
E, make bearing saddle bore become a full circle gear case body 10,20 zoariums, precision machined bearing seat hole is used to guarantee the fitness behind gear case body 10,20 zoariums; Casing is placed on the vertical machining centre VF-8, use top jack-up, centering casing center line also clamps, precision machined bearing seat hole, and the bearing saddle bore in this step comprises driving and driven gear shaft holder hole 2,5;
F, with gear-box 10,20 splits, be benchmark with the bearing saddle bore after the fine finishining of gear case body 10 2, use boring machine machining box bottom inside 4.Use special tooling that the die joint level of casing is made progress during clamping, the main shaft of adjusting lathe is consistent with the axis of bearing saddle bore, boring spindle connects the special-purpose lengthening knife bar, and main shaft gyration drives knife bar processing, uses in the process to end drift to check whether process qualified.
Other processing parts of described gear case body 10 are interted and are processed in above-mentioned steps.Process when the roughing die joint as observation window, oil filler point, the screwed hole of oil gauge, drain oil, bearing saddle bore end face is processed on vertical machining centre when mould assembling precision machined bearing seat hole.
Method of the present invention has improved the qualification rate of product greatly, improved because the productivity ratio lower situation that artificial polishing brings, and the thickness that has guaranteed the gear case body bottom is in the margin of tolerance.By original technology is optimized, reduce the manpower waste, improve yield rate, the technique effect highly significant of acquisition.
