Abstract
The utility model discloses a straightness protection device used for processing of small-diameter cylindrical parts. The straightness protection device comprises a chuck, a protective jacket and a tip cone. The protective jacket sleeves the tip cone, and a workpiece clamped through the chuck is sleeved in the protective jacket and is abutted against the tip of the tip cone. The straightness protection device has the advantages that the workpiece is sleeved in the protective jacket and the diameter of the protective jacket is slightly larger than that of the workpiece, and the workpiece is axially fixed through the tip cone and rotates in the protective jacket during processing, so that vibration and bending generated from cutting are avoided, operation efficiency is improved, and processing quality of the workpiece is guaranteed.
Description
Technical field
The utility model relates to a kind of linearity protective device, and more specifically, it relates to a kind of linearity protective device for the processing of small-diameter circular cylindricality part.
Background technology
Mechanical processing process refers to all processes of making product from raw material or semi-finished product, if a small-diameter circular cylindricality workpiece is processed, workpiece when rotated, because can making workpiece, machine cut power produces vibration and bending, change its linearity, so just reduced operating efficiency and quality.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, good stability, the linearity protective device for the processing of small-diameter circular cylindricality part that efficiency is high.
This linearity protective device for the processing of small-diameter circular cylindricality part; comprise chuck; also comprise protective sleeve and addendum cone, described protective sleeve is sleeved on described addendum cone, and the workpiece of described chuck clamping is set in described protective sleeve and is resisted against the tip of described addendum cone.
As preferably: be fixedly mounted on described addendum cone by locking nut on described protective sleeve.
As preferably: the slightly larger in diameter of described protective sleeve is in the diameter of described workpiece.
As preferably: described protective sleeve mid portion is provided with workpiece machining area, and the angle that the protection jacket wall cross section of described machining area becomes with horizontal plane is 10 to 30 degree.
The beneficial effects of the utility model are: the linearity protective device for the processing of small-diameter circular cylindricality part described in the utility model; by being set with slightly larger in diameter in the protective sleeve of diameter of work on workpiece; make workpiece axial restraint by addendum cone; in protective sleeve, rotate adding man-hour workpiece; the vibration and the bending that while having avoided cutting, have produced; thereby improve operating efficiency, ensured the crudy of workpiece.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 be in Fig. 1 A-A to cutaway view;
Reference numeral: chuck 1, protective sleeve 2, workpiece 3, locking nut 4, addendum cone 5.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model is described in connection with preferred embodiment, should know, do not represent that the utility model is limited in described embodiment.On the contrary, the utility model is by alternative, modified and the equivalent contained in the scope of the present utility model that can be included in attached claims restriction.
As shown in Figure 1; the utility model comprises chuck 1, protective sleeve 2 and addendum cone 5; protective sleeve 2 is sleeved on addendum cone 5; the workpiece of chuck 1 clamping is set in protective sleeve 2 and is resisted against the tip of addendum cone 5; on protective sleeve 2, be fixedly mounted on addendum cone 5 by locking nut 4; the slightly larger in diameter of protective sleeve 2 is in the diameter of workpiece, and protective sleeve 2 mid portions are provided with workpiece machining area, and the angle theta that the protection jacket wall cross section of machining area becomes with horizontal plane is 10 to 30 degree.
The operation principle of the linearity protective device for the processing of small-diameter circular cylindricality part described in the utility model is as follows:
Protective sleeve 2 use 45 steel in the utility model are made; and quench; its internal diameter is slightly larger than the external diameter of workpiece; just in time be slidably matched with workpiece 3 external diameters; locking nut 4 is locked; press the direction shown in Fig. 1; protective sleeve 2 is fixed on addendum cone 5, when use, workpiece 3 is placed in protective sleeve 2; one end utilizes chuck 1 to block; one end heads on workpiece 3 with addendum cone 5, and workpiece 3, in the interior rotation of protective sleeve 2, has just been avoided the vibration and the bending that while cutting, produce; thereby improve operating efficiency, ensured the crudy of workpiece 3.
