Problems solved by technology

[0015] In order to solve the problems of low production efficiency of the traditional counterweight processing method, heavy labor and unstable quality of manually removing the burrs at the intersection of the large hole and the small hole, the present invention provides a processing method of the counterweight block, which uses a spherical milling cutter to reverse The inner corners ensure the quality of the inner corners; the blank casting of the counterweight has reserved holes, which greatly reduces the processing workload.

Embodiment Construction

[0033] The processing method of the counterweight block of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 , figure 2 Shown, the processing method of counterweight block of the present invention, comprises the following steps:

[0035] Step 1, milling positioning surface A, reaming large hole 1, flipping and milling positioning surface B, chamfering the large hole;

[0036] Step 2, positioning the large hole 1, and reaming the small hole 2;

[0037] Step 3, positioning the large hole 1, chamfering the inner corner 3 at the intersection of the large hole 1 and the small hole 2;

[0038] Step 4, chamfering the end face of the small hole 2;

[0039] Step five, spray paint;

[0040] Step 6, finely ream large hole 1 and small hole 2.

[0041] After the above steps, the processing of the counterweight is completed. The above steps 2 and 3 are carried out on the turning center, which can ...

Abstract

The invention relates to a processing method of a clump weight. The processing weight of the clump weight comprises the following steps: milling one end face, reaming a large hole, turning over the end face and milling the other end face, chamfering the large hole; reaming a small hole; chamfering a junction of an interior angle of the large hole and the small hole through a spherical milling cutter; chamfering the small hole; spraying and painting paint; precisely reaming the large hole and the small hole. According to the processing weight of the clump weight, the spherical milling cutter is adopted to chamfer the interior angle, compared with the effect of a traditional manual burr materials removing, the processing method of the clump weight is stable with high production efficiency, at the same time batches processing is conducted through a concentrative process of a turning center, and the production efficiency is increased to over 300 percent compared with the production efficiency of a traditional single-piece processing.

Description

technical field [0001] The invention belongs to the field of auto parts processing, and in particular relates to a processing method for a counterweight used in an auto gearbox. Background technique [0002] As one of the most important components in the automobile transmission system, the automobile transmission undertakes the important task of changing the torque and speed of the entire automobile and shifting gears of the automobile. With the continuous improvement of consumers' driving comfort, at present, some automobile gearboxes generally adopt the method of adding counterweights in order to improve the shift feel. The traditional counterweight blank has no casting reserved holes and is processed in a single piece, including the following processing steps: [0003] Step 1, car positioning surfaces A and B; [0004] Step 2, Drill large and small holes; [0005] Step 3, rough boring the big hole; [0006] Step 4, fine boring large holes; [0007] Step 5, large hole...
