Abstract

The invention relates to a ball pin manufacture process. The process has the following procedures: roughly boring a hole: a CK6130 numerical-control lathe is used for roughly turning ball heads, and the surface roughness is 6.4; and rolling and rubbing ball heads: a thread rolling machine and a smooth board are used for rolling and rubbing processing, the surface roughness of the ball heads is within 0.8, and the finish of the ball heads is controlled to be within 0.05. The ball heads are processed by rolling and rubbing, and the surface finish can reach 0.8; after the rolling and rubbing processing is adopted, the production efficiency is increased by 40-60%.

Description

Ball pin manufacture process

Technical field

The present invention relates to a kind of new manufacturing process of ball pin, be used for the automobile joint and connect, belong to the car gear shifting technical field.

Background technology

Ball pin bulb position ubiquity fineness in the market is not enough, and the relatively poor problem of gear shift sensitivity when car gear shifting, traditional processing method are to adopt lathe turning to process.Traditional manufacture exists inefficiency, the not enough problem of bulb position fineness, is difficult to satisfy client's demand.

Summary of the invention

1, technical problem to be solved:

The invention provides at above deficiency a kind of cheap, the ball pin manufacturing process and product that quality is higher.

2, technical scheme:

Process route of the present invention is:

Rough bore: adopt the rough turn bulb of CK6130 numerically controlled lathe, surface roughness is 6.4;

Head rolls, chops the chop: adopt thread rolling machine and tabula rasa to roll, rub with the hands processing, the bulb surface roughness reaches in 0.8, and the bulb precision is controlled in 0.05.

3, beneficial effect

Bulb of the present invention adopts and rolls, rub with the hands and process, and the bulb surface smoothness can reach 0.8; Employing is rolled, is rubbed with the hands processing efficient and improved 40-60%.

The specific embodiment

Below in conjunction with the specific embodiment the present invention is done explanation in further detail.

Process route of the present invention: rough turn bulb → roll, the head of chopping the chop

Rough bore: adopt the rough turn bulb of CK6130 numerically controlled lathe, surface roughness 6.4

Head rolls, chops the chop: adopt thread rolling machine and tabula rasa to roll, rub with the hands processing, the bulb surface roughness can reach in 0.8, and the bulb precision can be controlled in 0.05.

The major technique feature of the bulb after rolling, rubbing processing with the hands:

1, the bulb surface roughness can reach in 0.8;

2, the bulb precision can be controlled in 0.05.

Bulb quality of the present invention, dependable performance, production efficiency first mate improves, and cost obviously descends, and can satisfy client's demand.

Though the present invention with preferred embodiment openly as above; but they are not to be used for limiting the present invention; anyly be familiar with this skill person; without departing from the spirit and scope of the invention; from when can doing various variations or retouching, so being as the criterion of should being defined with the application's claim protection domain of protection scope of the present invention.

Claims (1)

1, a kind of ball pin manufacture process is characterized in that: process route is:

Rough bore: adopt the rough turn bulb of CK6130 numerically controlled lathe, surface roughness is 6.4;

Head rolls, chops the chop: adopt thread rolling machine and tabula rasa to roll, rub with the hands processing, the bulb surface roughness reaches in 0.8, and the bulb precision is controlled in 0.05.
