Abstract
The utility model discloses a special machine tool for a balance shaft bracket boring tooling of an automobile. The special machine tool comprises a lathe and a clamp, wherein a four-jaw chuck is arranged on the lathe; a ring flange is clamped by the four-jaw chuck; the clamp comprises a fixed base plate, a reinforcing plate and a positioning cushion block; two positioning pins are arranged on the positioning cushion block; a pull rod bolt pressing plate for fastening and clamping a workpiece is arranged above the clamp; a central line of a lathe spindle is aligned to that of the workpiece; and a semispherical balance block is arranged on the surface opposite to the workpiece fixing base plate of the ring flange. According to the special machine tool for the balance shaft bracket boring tooling of the automobile, which is disclosed by the utility model, the positioning by adopting two positioning pins and three-point positioning by adopting an inside rectangular backing plate are realized; and the center of a balance shaft bracket hole is adjusted to be superposed with the center of the lathe spindle, so that the processing precision of parts can be better ensured, the processing efficiency is increased and the labor intensity of workers is reduced.
Description
Technical field
The utility model relates to field of automobile, specifically, relates to a kind of automobile balance bracing strut boring technological equipment special purpose machine tool.
Background technology
The trunnion shaft support is the strength member in the connection shaft support assembling component, connection shaft support assembling component be assemblied in multi-wheeler in, on the back axle, in the assurance, all wheels of back axle all with ground have good contact reach in, each wheel vertical load of back axle is equal.The trunnion shaft support then be in, the fulcrum that distributes of the vertical load between back axle front and back wheel adjustment.Trunnion shaft support boring endoporus operation is used the CW6280C lathe, guarantees that size is 3 sizes such as centre-height, and wherein the endoporus interlude requires the bore hole band to go deep into stepped hole, and also will be pressed into copper base lining in the endoporus; So general boring machine can't satisfy processing request, has only the small tool traverse feed that utilizes lathe to process.
Prior art, general boring machine can't satisfy processing request, has only the small tool traverse feed that utilizes lathe to process, this kind processing mode low precision, working (machining) efficiency is low, can't satisfy the needs of mass production.

The specific embodiment
Followingly the utility model is carried out detailed explanation with reference to accompanying drawing and embodiment:
Accompanying drawing 1-2 can know that a kind of automobile balance bracing strut boring technological equipment special purpose machine tool comprises lathe and anchor clamps; Said lathe is provided with chuck, and four-jaw chuck clamp is held ring flange 5, and said anchor clamps comprise fixed base plate 3; Stiffener 4, spacer pad 7, spacer pad 7 is provided with alignment pin 2; The anchor clamps top is provided with the stay-bolt pressing plate with the fastening clamping of workpiece; The center line of lathe spindle center line alignment pieces; The right opposite of the workpiece fixed base plate of said ring flange is furnished with semi-circular counterweight; Said alignment pin 2 is 2.
The utility model automobile balance bracing strut boring technological equipment special purpose machine tool; Adopt two alignment pin location and the three-point fix of inboard rectangle backing plate; Trunnion shaft bracket holes center transferred to the lathe spindle center overlap; Can guarantee part processing precision well, improve working (machining) efficiency and reduce labor strength.
The utility model automobile balance bracing strut boring technological equipment special purpose machine tool, trunnion shaft support boring endoporus operation is used the CW6280C lathe, requires to guarantee 3 sizes of size, wherein requires the bore hole band to go deep into step in the middle of the endoporus, and also will be pressed into copper base lining in the endoporus; The employing spacing is that two alignment pins of D=400 are located and the three-point fix of inboard rectangle backing plate, trunnion shaft bracket holes center is transferred to the lathe spindle center overlap, and guarantees the high H of workpiece hole to center ± 0.03.
In order to adapt to the processing needs of dissimilar trunnion shaft supports, the pitch-row alignment pin of trunnion shaft bracket base locating hole and datum level have different behavior tolerance and dimensional requirement, can adjust and change corresponding locating piece to satisfy the processing needs of series of products.
