Abstract
A method for machining an air compressor crankcase comprises the following machining steps of (1) casting a blank, (2) lathing an inner hole A, an end face thereof and an outer circle, (3) milling the end face, (4) drilling a threaded hole bottom hole, (5) tapping a threaded hole and (6) checking the crankcase according to a drawing and delivering the crankcase to a storehouse. The method improves product part quality, prolongs the service life of equipment, and lowers production cost. The method is used for producing air compressor accessories.
Description
Technical field
The invention belongs to air compressor machine accessory field, specially refer to the processing method of air compressor crankcase.
Background technology
At present, crankcase is one of vitals of air compressor machine, and the dimensional tolerance precision of crankcase, form and position tolerance precision and surface treatment are to having a great impact in interchangeability, assembly performance and service life.The crankcase easy fracture that existing processing method is produced, seriously jeopardizes use safety, and Hui Gei enterprise and society bring very large loss, and processed complex, production cost are higher.The fracture of crankcase has become problem demanding prompt solution in industry.
Summary of the invention
The object of this invention is to provide a kind of energy easy to process, improve the quality of products and service life, the processing method of the crankcase reducing production costs.
The present invention is achieved in that the processing method of air compressor crankcase, it is characterized in that: comprise following procedure of processing:
1), rough-cast;
2), on lathe, with special fixture, press from both sides positive crankcase shell square toes, selecting the speed of mainshaft is 1000 revs/min, car: endoporus A and end face, cylindrical and corresponding circular arc and chamfering, each dimensioned is to design drawing requirement, with go-no go gauge, depth gauge rule and height gauge check;
3), on milling machine, with special fixture, press from both sides positive crankcase shell, selecting the speed of mainshaft is 1000 revs/min, milling: end face, and in process, control end, in the face of the depth of parallelism of endoporus A, is machined to design drawing requirement, with appliance special for detecting, checks;
4), on drilling machine, with fixture, press from both sides positive crankcase shell, auger shell pit A bottom outlet, checks with slide measure;
5), on tapping machine, tapping thread mill drilling A, each dimensioned is to design drawing requirement, with slide measure, screw gauge check;
