Abstract
The invention discloses a processing technique of a planet carrier of a coal cutter. The processing technique of the planet carrier of the coal cutter comprises the steps of workblank forging or casting, destressing heat treatment, chemical component sampling and analyzing, rough machining, flaw detection, hardening and tempering, and finish machining. The finish machining relates to the steps of (1) milling four holes for installation of a planet wheel in the circumferential direction; (2) finish-turning the end face of a spline end and an outer circle, drilling, boring and reaming an inner hole, punching and tapping; (3) milling a spline; (4) turning around a workpiece to finish-turn the end face of the other end and an outer circle, and drilling, boring and reaming an inner hole. All steps of the rough machining and all steps of the finish machining are achieved on one machining device. According to the processing technique of the planet carrier of the coal cutter, multi-step machining is achieved by means of the one machining device, and therefore the integration level is high; due to the fact that grinding is replaced with turning during the finish machining, machining efficiency is improved, and the accuracy of a finished surface can be guaranteed.
Description
Technical field
The present invention relates to a kind of processing method of planet carrier, more particularly, relate to a kind of technological method for processing of coal-winning machine planet carrier, belong to machine components process technology.
Background technology
Planet carrier is one of main member of planetary transmission, and the part being connected with planetary gear has water seal seat (directly connecting by bolt), adapter sleeve, bearing block, rocking arm, planetary gear, sun gear.Planetary gear, as basic building block, is the part that bears moment of face maximum in gear drive; The accuracy of manufacture of planetary gear is for the load distribution between each planetary gear to such an extent as to transmission dress all has very important status.
Existing coal-winning machine planet carrier machining process comprises normalizing heat treatment, chemical composition analysis, Vehicle Processing for the first time, flaw detection, modified heat treatment, half finish turning, boring, line cutting, draws punching center line, boring, finish turning, mill, bore hole, annular knurl key, boring, cusped edge abate and finishing fillet, warehouse-in after finally checking.In whole process, the equipment of machining has: six kinds of equipment such as lathe, drilling machine, line cutting, face plate, cylindrical bed, gear-hobbing machine, and to prepare ending work hour and be about 8 hours 20 minutes, machined man-hour is 51.7 hours.The processing of a part, needs even tens procedures of several roads, tens roads, need to complete through the processing of too much platform polytype equipment, also will prepare various frock clamps.Whole machining period is long, and precision is difficult to guarantee, needs a large amount of manually, and production efficiency low cost is high.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, task of the present invention has been to provide a kind of process for machining method of coal-winning machine planet carrier, reduces the number of devices adopting in technical process, shortens machining period, improves precision.
Technical scheme of the present invention is such, and a kind of technological method for processing of coal-winning machine planet carrier, is characterized in that: comprise blank forging or casting, destressing heat treatment, chemical composition sample analysis, roughing, flaw detection, modified, fine finishining;
Described roughing step comprises the Si Ge hole of a. milling circular direction installation planetary gear, stays allowance for finish; B. car splined end end face, cylindrical, bore boring endoporus, stays allowance for finish; C. workpiece turns around, and car other end end face, cylindrical bore boring endoporus, stay allowance for finish;
Described fine finishining step comprises the Si Ge hole of a. milling circular direction installation planetary gear; B. finish turning splined end end face, cylindrical, brill, boring, hinge endoporus, boring, tapping; C. milling spline; D. workpiece turns around, finish turning other end end face, cylindrical, brill, boring, hinge endoporus;
Each step of described roughing and fine finishining all completes on a process equipment.
Preferably, described roughing step a and fine finishining step a, c add man-hour, and milling cutter is by horizontal direction feeding.
Technological method for processing of the present invention is by six kinds of equipment such as original lathe, drilling machine, line cutting, face plate, cylindrical grinder, gear-hobbing machines, be integrated into a kind of equipment, adopt double-workbench, workbench pallet calibration 90 is spent the time only needs 1.8 seconds, only 11 seconds swap time of pallet, a workbench adds man-hour, and another workbench is prepared, machined man-hour is single-piece 6 hours, and working (machining) efficiency is high.In fine finishining step b, " with car for mill " changed planet carrier processing and must adopt grinding machine to process to reach the traditional handicraft thinking of required precision, employing full depth, high workpiece rotational frequency, and its metal resection rate is 3～4 times of grinding normally; Its energy consuming also only has 1/5 of grinding, and the cost of charp tool of each part is lower than grinding.Changing in addition emery wheel generally needs 30min or longer time, and " with car for mill " tool changing completed within 1 minute, and do not need to revise emery wheel cutting profile, the loss of the production time of not have to change, correction emery wheel is essential, and the utilization rate of lathe is high.Adopt in addition cutting tool coated with hard alloy cutting energy to obtain equal or better surface smoothness with obviously higher metal resection rate, most of heat of producing in turning is taken away by smear metal, can not produce scorch and crackle as grinding, there is good machined surface quality, there is accurate processing circularity, can guarantee finished surface precision.
The specific embodiment
Below in conjunction with embodiment, the invention will be further described.
The turn-milling complex machining center of take processing coal-winning machine planet carrier is example, and technological method for processing, comprises blank forging or casting, destressing heat treatment, chemical composition sample analysis, roughing, flaw detection, modified, fine finishining.During roughing, installation calibrating workpiece on turn-milling complex machining center work top, one end that workpiece to be processed is had to a spline is upward, utilize " right-angle milling head ", milling cutter is installed, allow milling cutter horizontal feed, milling circular direction is installed the Si Ge hole of planetary gear, the monolateral allowance for finish 2.5mm that stays; Car splined end end face, cylindrical, bore boring endoporus, the monolateral allowance for finish 1.5mm that stays; Workpiece turns around, and car other end end face, cylindrical bore boring endoporus, the monolateral allowance for finish 1.5mm that stays.During fine finishining, installation calibrating workpiece on turn-milling complex machining center work top, has one end of spline upward, utilizes " right-angle milling head ", and milling cutter is installed, and size is arrived in the Si Ge hole that allows milling cutter horizontal feed, milling circular direction that planetary gear is installed; With car, for mill, adopt cutting tool coated with hard alloy finish turning splined end end face, cylindrical; Brill, boring, hinge endoporus; Boring, tapping; Utilize " right-angle milling head ", spline cutter is installed, milling spline is to size; Workpiece turns around, on positioning tool, live, with car for mill, finish turning car other end end face, cylindrical, brill, boring, hinge endoporus are to size.During roughing, single workpiece machining period is 120min, and during fine finishining, single workpiece machining period is 240min, compares former processes and significantly shortens man-hour.
