Abstract
The invention relates to the field of machining, in particular to a machining method for a reduction case. The machining method comprises the following steps that the reduction case is milled on a planer type milling machine; a case assembling face is roughly and precisely milled, that is, the case, the upper plane of a case cover and the lower plane of the case cover are roughly and precisely milled, and a case bottom plane is machined; a reducer machine body and a reducer machine cover are assembled and adjusted to be in place, a bolt hole and a pin hole in the machine body are drilled, all the holes are deburred, the machine body, a bolt on the machine cover and a cone pin on the machine cover are assembled according to requirements, and fastening of the bolt reaches the requirement; an inner hole is roughly bored; a bearing pedestal is precisely bored until the required size is achieved, and an annular groove is machined until the required size is achieved; the matched bearing face screw hole is scratched, drilled and tapped to the required size, and a bearing pedestal through hole is drilled; the machine body and the machine cover are dismounted; an oil returning hole on a bearing cover and a hole in the end face of the bearing cover are scratched and drilled to the required size; a screw hole in a sight hole above the machine cover is scratched, drilled and tapped to the required size; a machine body ground foot hole is scratched and drilled to the required size; and checking is carried out. The machining process is simple, the product machining precision can be ensured, the production efficiency is improved, and the production cost is effectively reduced.
Description
Technical field
The present invention relates to field of machining, be specifically related to reduction case processing method.
Background technology
Decelerator is generally used for the drive apparatus of low rotation speed large torque, utilizes the velocity transducer of gear, and the rotating speed of motor is dropped to desired rotating speed, and obtains larger torque.Output torque equals motor output speeds and takes advantage of speed reducing ratio, but will note exceeding decelerator nominal torque.We roughly can be divided into planetary reduction gear, worm type of reduction gearing, reducer with hardened tooth surface, soft flank of tooth decelerator etc. by common decelerator.In reducer structure primarily of reduction case, tooth axle, output shaft, gear ring, wheel hub etc. five part composition, but there is certain difficulty in the processing of reduction case, low to the processing method production efficiency of reduction case at present, and the product percent of pass of producing is lower.
Summary of the invention
In order to solve the problem, the invention provides a kind of process simple, can processing precision of products be ensured, the reduction case processing method of enhancing productivity.
Reduction case processing method of the present invention, comprises the following steps:
The first step, milling, planer-type milling machine carries out milling to reduction case; Slightly, finish-milling casing mould assembling face i.e. casing and case lid lower planes, processing case baseplane, to reach the requirement of drawing plane degree;
Second step, drilling: decelerator body and the mould assembling of decelerator cover are adjusted to the right place, body of drill upper bolt hole and pin-and-hole, bolt, taper pin on body and cover are assembled in the deburring of each hole on request, and bolted reaches requirement;
3rd step, boring, corrects end face and endoporus, and heavy boring endoporus, stays 3 ~ 4mm allowance for finish respectively; Right boring bearing block is to requiring size, and process cannelure to requiring size, endoporus bar boring, a cutter completes processing;
3rd step, drilling, chamfering bit attacks fitted shaft bearing surface screw to requiring size, auger spindle bearing through hole; Remove body, cover, spill port on chamfering bit bearing cap with hole on end face to requiring size; Chamfering bit to attack above cover window place screw to requiring size; Chamfering bit body lower margin hole is to requiring size;
4th step, polishing: deburring;
5th step, inspection.
Process of the present invention is simple, can ensure processing precision of products, enhance productivity, effectively reduce production cost.
