Abstract
The invention relates to a processing technique for an automobile brake drum. The processing technique is characterized by comprising the following steps: firstly casting a brake drum blank; sequentially processing the brake drum blank; drilling a bottom threaded hole, a through hole, a tap and a chamfer at a processing center; performing honing treatment on the inner hole on a honing machine till the overlapping curve depth reaches more than or equal to 0.1mm. The initial braking force of the inner surface of the products can reach the technical requirement; the position accuracy of the mounting hole and the thread hole is high; the consistency of the products is excellent; the production efficiency is high and the cost is low; the processing technique has the value of popularization and application.
Description
Technical field
The present invention relates to a kind of auto parts and components processing method, particularly a kind of automobile brake drum processing technology.
Background technology
At present, automobile brake drum generally adopts Mechanical processing of casting to make, and after processing, endoporus does not do honing processing, affects its initial brake force and does not reach technical requirement. Secondly, the screwed hole on brake drum adopts bushing plate boring mostly, and the position precision in each hole is difficult to reach designing requirement, and product percent of pass is low, and production efficiency is low, cost is high.
Summary of the invention
The object of the invention is the above-mentioned weak point in order to overcome prior art, and a kind of high conformity of product is provided, precision is high, steady quality is reliable, the automobile brake drum processing technology that production efficiency is high, cost is low.
For achieving the above object, the concrete technology method that the present invention adopts is first to cast brake drum blank, again brake drum blank is carried out to order processing: with end face and Internal hole positioning, a rough turn end face, endoporus and chamfering, rough turn other end, tune location, endoporus and chamfering, clamp with an end face and Internal hole positioning, fine turning outer circle, end face and chamfering, half finish turning endoporus, groove and chamfering, use special grooving cutter to cut out end face groove, tune clamps with endoporus and grooving end face location, finish turning other end endoporus, end face and chamfering, work in-process bores thread Pilot hole in the heart, through hole, tapping, chamfering, brake drum workpiece through above-mentioned processing is placed in to the enterprising action balance check of dynamic balancing machine, at the special purpose machine tool amount of unbalance of getting on the bus, on honing machine, endoporus is carried out more than honing processes and reach 0.1mm to the reticulate pattern degree of depth, clean up and apply water-based antirust agent and become product.
The present invention is owing to adopting above process, and the initial brake force of product inner surface can reach technical requirement, and the position precision of installing hole, screwed hole is high, the high conformity of product, and production efficiency is high, cost is low, has application value.
Detailed description of the invention
First cast brake drum blank, and remove cast gate on blank, lip-deep molding sand, again brake drum blank is carried out to order processing: with end face and Internal hole positioning, a rough turn end face, endoporus and chamfering, rough turn other end, tune location, endoporus and chamfering, clamp with an end face and Internal hole positioning, fine turning outer circle, end face and chamfering, half finish turning endoporus, groove and chamfering, use special grooving cutter to cut out end face groove, tune clamps with endoporus and grooving end face location, finish turning other end endoporus, end face and chamfering, work in-process bores thread Pilot hole in the heart, through hole, tapping, chamfering, brake drum workpiece through above-mentioned processing is placed in to the enterprising action balance check of dynamic balancing machine, at the special purpose machine tool amount of unbalance of getting on the bus, on honing machine, endoporus is carried out more than honing processes and reach 0.1mm to the reticulate pattern degree of depth, clean up and apply water-based antirust agent and become product.
