Abstract
The utility model provides a round chuck. The round chuck comprises a sleeve and a shaft sleeve which is sleeved on one end surface of the sleeve, and is used for being fixed on a lathe spindle cartridge. The round chuck is characterized in that the other end surface of the sleeve is provided with a centering clamping element. The round chuck provided by the utility model has the beneficial effects that according to the round chuck provided by the utility model, the outer diameter of the chuck is designed to be equivalent to the radius of an inner pipe of a clamped workpiece; the chuck butts against the inner pipe of the workpiece; a clamping claw extends into the inner pipe, and clamps a shaft core; the round chuck is simple in structure, clamps more firmly because of the reduction of a clamped area, is difficult to loose, and cannot easily clamp and damage the workpiece.
Description
Technical field
The utility model relates to a kind of chuck, relates in particular to a kind of round chuck that is applicable to clamping Small Cylindrical product.
Background technology
Chuck is to be used for fixing a kind of fixture of reinforcing because of the part of needs transformation, is the chief component of technological equipment, affects to a great extent quality, productivity ratio and the production cost of engineering goods.The circle chuck, as the term suggests be to be used for fixing the chuck that profile is round piece, as shown in Figure 1, the periphery of the direct holding workpiece of jaw of holding workpiece chuck, include whole workpiece in jaw existing round chuck, the piece-holder effect that this mode is large to length, quality is heavy is fine, but less for length, quality is light, monolateral too thin workpiece is inapplicable, easily clamping is loosening, affects follow-up machining, easily crush simultaneously the outer surface of workpiece, cause the workpiece bad order.
Summary of the invention
In order to solve the deficiency in background technology, the purpose of this utility model is to overcome the defect of background technology, and a kind of round chuck is provided, simple in structure, clamping firmly, be difficult for crushing workpiece.
For achieving the above object, the technical solution adopted in the utility model is: a kind of round chuck, comprise sleeve and the axle sleeve fixing with the lathe spindle chuck that be used for that is sheathed on described sleeve one end face, it is characterized in that: the other end of described sleeve is provided with the centering clamping element.
In preferred embodiment of the utility model, further comprise described centering clamping element comprise the rounded chuck in cross section with the coaxial axostylus axostyle that is connected of described chuck.
In preferred embodiment of the utility model, the radius that further comprises described chuck with added the inner tube radius of holding workpiece and equated.
In preferred embodiment of the utility model, comprise that further described axostylus axostyle is provided with a plurality of jaws.
In preferred embodiment of the utility model, the number that further comprises described jaw is four, along the circumferential equal angles of described axostylus axostyle, distributes.
In preferred embodiment of the utility model, further comprise on described axostylus axostyle and also be connected with the cylinder that drives described jaw activity, described axostylus axostyle is connected with the push rod of described cylinder.
In preferred embodiment of the utility model, further comprise on the periphery wall of described sleeve and described axle sleeve and be equipped with anti-slip veins.
Usefulness of the present utility model is: a kind of round chuck of the present utility model, the external diameter of chuck is designed to be added the inner tube radius of holding workpiece suitable, chuck docks with the inner tube of workpiece, jaw puts in inner tube the inside clamp shaft core, simple in structure, simultaneously, make clamping more firm because holding area dwindles, be difficult for becoming flexible, be not easy to crush workpiece.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of existing circle chuck;
Fig. 2 is the round chuck structure schematic diagram of the utility model preferred embodiment;
The top view of Fig. 3 the utility model preferred embodiment;
Fig. 4 is the Workpiece structure schematic diagram that needs clamping.
In figure: 2, sleeve, 4, axle sleeve, 6, the centering clamping element, 8, chuck, 10, axostylus axostyle, 12, jaw,, 14, anti-slip veins, 16, inner tube, 18, the axle core.
The specific embodiment
In order to make those skilled in the art person understand better the utility model scheme, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the utility model is described in further detail.
As Fig. 2-shown in Figure 4, a kind of round chuck comprises sleeve 2 and is sheathed on the axle sleeve 4 of sleeve 2 one end faces that the other end of sleeve 2 is provided with centering clamping element 6.Axle sleeve 4 is used for whole round chuck is fixed on the lathe spindle chuck, by centering clamping element 6, fixes and clamps workpiece to be processed.For convenient for assembly, be equipped with anti-slip veins 14 on the periphery wall of sleeve 2 and axle sleeve 4, the design of anti-slip veins 14 is used for anti-skidding, makes operating personnel easily be affectedly bashful in the assembly and disassembly process, avoids dropping and injuring personnel by a crashing object because being affectedly bashful shakiness.
Centering clamping element 6 comprises cross section rounded chuck 8 and the coaxial axostylus axostyle 10 that is arranged on chuck 8 inside.
Axostylus axostyle 10 is provided with a plurality of jaws 12, and jaw 12 is used for holding workpiece.Jaw 12 can be two, three or a plurality of, considers the degree and the cost that clamp, and the number of preferred jaw 12 is four, and along the circumferential equal angles of axostylus axostyle 10, distributes, and clamping effect like this is best.The external cylinder of axostylus axostyle 10 (not shown), be connected with the push rod (not shown) of cylinder, and axostylus axostyle 10 driving by cylinder (not shown), to jaw 12, drives the power transmission jaw 12 and moves along clamping direction.During work, jaw 12 puts in inner tube 16 the inside clamping work pieces.
The radius of chuck 8 equates with inner tube 16 radiuses that are held workpiece, when making clamping, jaw 12 puts in the direct clamp axis core 18 in the inside of inner tube 16, what justify like this chuck contact is the outer surface of inner tube 16, rather than whole workpiece, because dwindling, holding area make clamping more firm, be difficult for becoming flexible, be not easy to crush workpiece.
Above-described embodiment is the better embodiment of the utility model; but embodiment of the present utility model is not limited by the examples; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify the substitute mode that all should be equivalence, within being included in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
