Abstract

A method for machining an air conditioner end cover comprises the following machining steps of (1) casting an aluminum blank, (2) shot blasting, (3) lathing an inner hole and an end face thereof, and an outer circle and an end face thereof, (4) stamping hole burrs, (5) drilling threaded hole bottom holes, (6) taping threaded holes, and (7) checking the end cover according to a drawing and delivering the end cover to a storehouse. The method improves product quality, and prolongs the service life of equipment.

Description

The processing method of air conditioner end cap

Technical field

The invention belongs to air conditioner accessory field, specially refer to the processing method of air conditioner end cap.

Background technology

At present, end cap is one of vitals of air conditioner, and the dimensional tolerance precision of end cap, form and position tolerance precision and surface treatment are to having a great impact in interchangeability, assembly performance and service life.The end cap 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 end cap 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, the service life of extension device, the processing method of the end cap reducing production costs.

The present invention is achieved in that the processing method of air conditioner end cap, it is characterized in that: comprise following procedure of processing:

1), aluminium rough-cast;

2), ball blast: for 5～6 minutes ball time;

3), to take cylindrical C and end face D be benchmark, presss from both sides positive end cap cylindrical, car on lathe with three-jaw: endoporus and end face A, cylindrical and end face B and corresponding circular arc and chamfering, each dimensioned is to design drawing requirement, with slide measure, amount instrument, depth gauge rule check;

4), take end face D as benchmark, on hydraulic press, with mould fixing end lid, selection pressure is 3T, punching hole A, hole B burr, check with slide measure by drawing;

5), take end face D as benchmark, on drilling machine, with fixture folder anode cover housing, auger shell pit bottom outlet, checks with slide measure;

6), on tapping machine, tapping thread mill drilling, is machined to design drawing requirement, with screw gauge, checks;

7), press drawing check warehouse-in.

The invention enables end cap easy to process, improved the service life of product quality and equipment, reduced production cost.
