Abstract
The invention discloses a clamping tool for slender shaft machining. The clamping tool comprises a screw sleeve, a snapping sleeve, a shaft, a thrust bearing, isolating sleeves, radial bearings and an outer sleeve, wherein the screw sleeve is fixedly mounted at the left end of the shaft, and the snapping sleeve consists of two half sleeves and is arranged in the screw sleeve; the thrust bearing and the radial bearings are mounted on the shaft, the isolating sleeves are arranged between the thrust bearing and the radial bearings, the outer sleeve is sleeved on the shaft, the left end face of the thrust bearing is abutted against the inner end face of the outer sleeve, and holding screws are arranged on the sidewall of the outer sleeve. By using the clamping tool for the clamping and turning of a slender shaft, the two ends of the slender shaft are subjected to the action of tensile force, so that the rigidity of a workpiece is enhanced, the vibration of the workpiece is reduced, the stability of machining is improved, the hot-deformation elongation of the workpiece is relieved, the accuracy of machining is guaranteed, and the machining accuracy can be increased.
Description
Technical field
The present invention relates to field of machining, particularly a kind of for the clamping fixing tool when the processing slim axle.
Background technology
Conventional Turning of Slender Shaft method is processed with top cooperation follow-rest.Due to the poor rigidity of slender axles own, be subject to the impact of lathe tool cutting force and top axial thrust in turning process, the as easy as rolling off a log generation flexural deformation of workpiece, rope skipping phenomenon appears while making the workpiece rotation, cause difficulty of processing large, even can't process, can not guarantee that like this crudy can not meet again the requirement that improves effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide and a kind ofly both can guarantees crudy, can improve working (machining) efficiency again, simple in structure, uses easy to operate slender axles processing and loading clamp frock.
For solving the problems of the technologies described above, the present invention has adopted a kind of slender axles processing and loading clamp frock, comprises swivel nut, cutting ferrule, axle, thrust bearing, spacer, radial bearing, overcoat, and described swivel nut is fixedly mounted on the axle left end, described cutting ferrule is comprised of two and half covers, is arranged in swivel nut; Described thrust bearing, radial bearing are arranged on axle, between described thrust bearing and radial bearing, are provided with spacer, and on described axle, cover has overcoat, and described thrust bearing left side withstands on the overcoat inner face, and described sleeve side wall is provided with holding screw.
A plurality of radial bearings are installed on described axle, between described radial bearing, are provided with spacer.
Described overcoat left end is provided with groove, in described groove, is provided with sealing gasket.
The beneficial effect that the present invention has: use this clamping tooling clamping turning slender axles, the tension power effect of slender axles two ends, strengthened the rigidity of workpiece, reduced the vibration of workpiece, improved processing stability, alleviated the thermal deformation elongation of workpiece, guaranteed machining accuracy, the workpiece axiality can reach 0.02, flexibility is less than 0.03, surface roughness can reach Ra1.6, improved working (machining) efficiency, the clamping tooling clamping has approximately saved for 1/3～1/2 time than traditional clamping turning slender axles, and clamping tooling is manufactured easily simple, cost is low, use simple to operation, can extensive use on engine lathe.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, lathe claw; 2, workpiece; 3, swivel nut; 4, cutting ferrule; 5, axle, 6, sealing gasket; 7, thrust bearing; 8, spacer; 9, radial bearing; 10, overcoat; 11, tail stock sleeve; 12, trip bolt.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
A kind of slender axles processing and loading clamp frock as shown in Figure 1, comprise swivel nut 3, cutting ferrule 4, axle 5, thrust bearing 7, spacer 8, radial bearing 9, overcoat 10, and swivel nut 3 is fixedly mounted on axle 5 left ends, and described cutting ferrule 4 is comprised of two and half covers, is arranged in swivel nut 3; Thrust bearing 7, radial bearing 9 are arranged on axle 5, between thrust bearing 7 and radial bearing 9, are provided with spacer 8, and on described axle 5, cover has overcoat 10, thrust bearing 7 left sides to withstand on overcoat 10 inner faces, and overcoat 10 sidewalls are provided with holding screw 12.
While using this frock, first overcoat 10 is enclosed within on tail stock sleeve 11, and utilizes the holding screw 12 on overcoat 10, frock is fixed on lathe.The cutting ferrule 4 of frock is comprised of two and half covers, and the technique draw-in groove of slender axles one end is stretched in swivel nut 3, in the swivel nut 3 of then two and half covers being packed into, be stuck in the technique draw-in groove of slender axles one end, thus fixation workpiece 2 right-hand members.Regulate the position of tail stock sleeve 11, workpiece left end clamping, on lathe clamps, is now completed to the clamping of workpiece.
A plurality of radial bearings 9 are installed on this tooling shaft 5, are provided with spacer 8 between radial bearing 9, a plurality of radial bearings 9 can make the operation of axle more stable, thereby guarantee the precision of processing.
Overcoat 10 left ends of this frock are provided with groove, are provided with sealing gasket 6 in groove, can prevent that flying dust from entering in axle 5, and affect the service life of bearing.
