Abstract
The utility model discloses a mould structure for fixing during lathing of a slender shaft. The mould structure comprises a lathe hollow shaft, a mould casing (1) is arranged at the rear end of the lathe hollow shaft, a tubular core body (2) is arranged in the mould casing (1), a screw (3) penetrates through threaded holes on the casing (1) and the core body (2), and an arc gasket (4) is arranged in the core body (2). After use, due to the fact that the rear end of the shaft is fixed by a mould, swinging and bending are avoided, precision of machining of the slender shaft is effectively improved, and potential safety hazards during machining of the slender shaft are completely avoided.
Description
Technical field
The utility model relate to a kind of on lathe the anchor clamps of locating shaft.
Background technology
During the Vehicle Processing slender axles, be that the hollow shaft that axle passes lathe is used the chuck clamping then, because the length of axle is long, external diameter is thin.Because axle that end in hollow shaft is not fixed, whipping, the bending easily of this part axle adds and phenomenons such as ellipse, tapering occur man-hour, and be easy to cause security incident.
Summary of the invention
The technical problem that the utility model will solve is: the problem that an end of the axle that exists to cars on hand processing slim axle can not get fixing provides a kind of positioner structure that axle is fixing that is used for.
The technical scheme of the utility model:
A kind of fixing positioner structure of slender axles Vehicle Processing that is used for comprises the lathe hollow shaft, in the rear end of lathe hollow shaft the mold housing is installed, and screw passes the screw on the mold housing, at the inner circular arc pad of placing of mold housing front end.
Mold housing rear end inwall has the threaded engagement on screw thread and the lathe hollow shaft rear end outer wall.
The thickness of circular arc pad is the difference of the radius of core body inwall radius and axle to be processed.
The beneficial effect that this use is novel: the length that can process can reach about 2.5 meters, and through the thickness of adjustment circular arc pad, machinable external diameter is between 45mm ~ 80mm.Because the rear end of axle is fixed by mold, no longer produces whipping and bending, effectively raises the precision of processing slim axle; Potential safety hazard when having avoided the processing slim axle fully.Use this positioner structure processing slim axle, working ability is original 2 times.
Description of drawings:
Fig. 1 is the utility model structural profile sketch map.
Fig. 2 is the utility model side schematic view.
The specific embodiment:
Like figure, in the rear end of lathe hollow shaft 2 mold housing 1 is installed, mold housing 1 rear end inwall has the threaded engagement on screw thread and the lathe hollow shaft 2 rear end outer walls.Screw 3 passes the screw on the mold housing 1; And in tool housing 1 front end, place circular arc pad 4; The thickness of circular arc pad 4 is the difference of the radius of core body inwall radius and axle to be processed, can adapt to different big or small axles through the up-down of adjustment screw 3 and the thickness of circular arc pad 4.The front end of axle is fixed through chuck, and the rear end is fixing with circular arc pad 4 through screw 3, thereby stability greatly improves.
Claims (3)
1. one kind is used for the fixing positioner structure of slender axles Vehicle Processing; Comprise the lathe hollow shaft; It is characterized in that: mold housing (1) is installed in the rear end at lathe hollow shaft (2); Screw (3) passes the screw on the mold housing (1), places circular arc pad (4) in mold housing (1) interior forward end.
2. the fixing positioner structure of slender axles Vehicle Processing that is used for according to claim 1, it is characterized in that: mold housing (1) rear end inwall has the threaded engagement on screw thread and the lathe hollow shaft rear end outer wall.
