Abstract
The invention discloses a car swing arm shaft processing process. The car swing arm shaft processing process is characterized in that swing arm shaft blank is firstly cast or forged, a sprue on the blank and molding sand on the surface are removed, and sequential processing is carried out as follows: the two end surfaces of the swing arm shaft are milled by utilizing a special milling machine, so that overall length dimension is guaranteed, central holes 3 are respectively drilled in the two end surfaces of the milled swing arm shaft by use of a central drill, and a coaxiality value of central holes in the two ends is guaranteed; rough turning and fine turning are sequentially carried out on an excircle at one end on a swing arm shaft processing center, and rough turning and fine turning are reversely carried out on an excircle at the other end; the swing arm shaft processing center is respectively turned with two-end threads; a special clamp is utilized on a swing arm shaft vertical processing center; two lug planes are subjected to rough turning and fine turning on one surface of the shaft; after flanging, the two lug planes on the other surface are subjected to rough turning and fine turning; in vertical processing, a special drilling clamp is utilized to roughly drill two bottom holes, expand holes and ream; and a drill bit is chamfered to remove burrs. The car swing arm shaft processing process is simple and convenient in operation, high in efficiency and low in cost; and the product is good in consistency, high in precision, stable and reliable in quality, and has a popularization and application value.
Description
Technical field
The present invention relates to a kind of machining process, particularly a kind of automobile swing arm axis processing technique.
Background technology
Automobile swing arm axle is mounted in a strength member on automobile swing arm, main transmission twisting force promotes that swing arm moves up and down, thus regulate chassis clearance and motor turning campaign, at present, in production and processing to it, generally adopt foundry goods or forging on machine tool, carry out the process of processing, the machining accuracy especially axiality at axle two ends is often difficult to reach designing requirement, and product percent of pass is low, exercise performance is poor.
Summary of the invention
The object of the invention is the above-mentioned weak point in order to overcome prior art, and provide a kind of uniformity of product good, precision is high, and steady quality is reliable, the automobile swing arm axis processing technique that production efficiency is high, cost is low.
For achieving the above object, the concrete technology method that the present invention adopts first casts or forge arm shaft blank, and remove cast gate on blank, molding sand on surface, carry out order processing again: utilize production miller, milling arm shaft both ends of the surface, ensure overall length dimension, centre drill is utilized to drill centre bore A3 respectively in the arm shaft both ends of the surface of milling, ensure the coaxial angle value of two ends centre bore, successively thick on arm shaft machining center, finish turning is one end cylindrical wherein, turn around thick, finish turning other end cylindrical, difference turning two ends screw thread on arm shaft machining center, in arm shaft vertical machining centre, utilize special fixture, thick in the one side of axle, finish-milling cuts two lug planes, after flange, slightly, finish-milling cuts another side two lug plane, in vertical processing, Special drill jig is utilized slightly to bore two bottom outlets, reaming and fraising, drill bit chamfering, deburring.
The present invention is owing to adopting above process, easy and simple to handle, and efficiency is high, cost is low, and the uniformity of product is good, and precision is high, and steady quality is reliable, has application value.
Detailed description of the invention
First casting or forging arm shaft blank, and remove cast gate on blank, molding sand on surface, carry out order processing again: utilize production miller, milling arm shaft both ends of the surface, ensure overall length dimension, centre drill is utilized to drill centre bore A3 respectively in the arm shaft both ends of the surface of milling, ensure the coaxial angle value of two ends centre bore, successively thick on arm shaft machining center, finish turning is one end cylindrical wherein, turn around thick, finish turning other end cylindrical, difference turning two ends screw thread on arm shaft machining center, in arm shaft vertical machining centre, utilize special fixture, thick in the one side of axle, finish-milling cuts two lug planes, after flange, slightly, finish-milling cuts another side two lug plane, in vertical processing, Special drill jig is utilized slightly to bore two bottom outlets, reaming and fraising, drill bit chamfering, deburring.
