Abstract
The utility model relates to a lathe fixture which comprises a spindle, wherein a fixture sleeve is arranged on the spindle; a taper hole is arranged in the fixture sleeve and shrunk toward the fixture sleeve inside; threads are arranged at a front end of the spindle; the spindle is connected with a fixing disk through threaded connection; at least three jack catches that can slide in the fixing disk radial direction are circularly arranged on the fixing disk; outer ends of the jack catch are inclined; the slope of the jack catch outer end is identical with that of the taper hole; a reversed T-shaped chute is arranged on the fixing disk; the jack catches can slide on the fixing disk through reversed T-shaped slide blocks arranged on the lower ends of the jack catches; and the amount of the jack catches is four. The lathe fixture has the advantages of simple structure, convenience in operation, can overcome the defect that the existing fixture should be clamped manually, greatly improve the clamping firmness of a workpiece, enable the processing precision of the workpiece to meet requirements, improve product quality, and increase processing yield of the workpiece.
Description
Technical field
The utility model relates to a kind of anchor clamps, and in particular a kind of anchor clamps that to need in order to clamping to be applied on the lathe workpiece of turning processing belong to the Workpiece clamping device technical field of machining.
Background technology
At present, on lathe, the employed anchor clamps of the workpiece of machining are mainly scroll chuck, comprise chuck body on the general scroll chuck; The bevel gear wheel that is provided with bevel pinion in the chuck body and meshes with bevel pinion, the chuck body upper clipping claw, bevel gear wheel links to each other with chuck; Have spanner on the bevel pinion and insert square hole; During use, T shape spanner is inserted in the square hole, thereby the rotation bevel pinion drives the slide purpose of the workpiece that reaches clamping mechanism processing of claw through bevel gear wheel.Such clamping mode needs manual clamping, and the tight and strength that does not tightly depend on the people fully of clamping workpiece is when people's strength is big; Workpiece is tight with regard to clamping; When people's strength hour, workpiece is not tight with regard to clamping, and the precision that tightly will not influence workpiece processing of clamping workpiece; Reduced product quality, made that the processed finished products rate of workpiece is low.
The utility model content
The utility model purpose is to provide a kind of clamping fastening turning attachment for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of turning attachment, comprise main shaft, and said main shaft is provided with the anchor clamps cover; Be provided with bellmouth and overlap internal contraction in the said anchor clamps cover to anchor clamps; The front end of said main shaft is provided with screw thread; On the said main shaft through the fixed disk that has been threaded; On the said fixed disk at least circular array show three claws that can slide along the fixed disk radial direction; The outer end of said claw is provided with gradient; The gradient of said claw outer end is identical with the gradient of bellmouth.
Preferably, have inverse-T-shaped chute on the said fixed disk; Said claw slides on fixed disk through the inverse-T-shaped slide block that the claw lower end is provided with.
Preferably, said claw is four.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The turning attachment of the utility model, simple in structure, easy and simple to handle.During use, the workpiece that needs turning processing is put between claw, when main shaft rotates; Fixed disk can screw in to the inside of anchor clamps cover; Because be provided with bellmouth in the anchor clamps cover, and the outer end of claw is provided with gradient, the gradient of claw outer end is identical with the gradient of bellmouth; So claw will draw in along the fixed disk radial direction, thereby reach the purpose of clamping work pieces.As long as main axis rotation is got up, workpiece just can not get loose, the deficiency that the anchor clamps before having overcome need manpower to clamp; Improved the firmness that workpiece clamps greatly; Make the workpiece machining accuracy satisfy requirement, improved product quality, increased the yield rate of workpiece processing.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of the turning attachment of the utility model;
Accompanying drawing 2 is the A-A cutaway view of accompanying drawing 1;
Accompanying drawing 3 is the user mode sketch map of the turning attachment of the utility model;
Wherein: 1, main shaft; 2, anchor clamps cover; 3, bellmouth; 4, screw thread; 5, fixed disk; 6, claw; 7, inverse-T-shaped chute; 8, inverse-T-shaped slide block; 9, workpiece.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Like accompanying drawing 1, the described a kind of turning attachment of the utility model shown in 2, comprise main shaft 1, said main shaft 1 is provided with anchor clamps cover 2; Be provided with bellmouth 3 and overlap internal contraction in the said anchor clamps cover 2 to anchor clamps; The front end of said main shaft 1 is provided with screw thread 4; Be connected with fixed disk 5 through screw thread 4 on the said main shaft 1; On the said fixed disk 5 at least circular array show three claws 6 that can slide along fixed disk 5 radial direction; Have inverse-T-shaped chute 7 on the said fixed disk 6; Said card 6 pawls slide on fixed disk 6 through the inverse-T-shaped slide block 8 that claw 6 lower ends are provided with; The outer end of said claw 6 is provided with gradient; The gradient of said claw 6 outer ends is identical with the gradient of bellmouth 3.
Above-mentioned turning attachment when said claw is four, clamps best results.
The described a kind of turning attachment of the utility model shown in accompanying drawing 3 during use, is put into 6 of four claws with the workpiece 9 that needs turning processing; When main shaft 1 rotated, fixed disk 6 can screw in to the inside of anchor clamps cover 2, owing to be provided with bellmouth in the anchor clamps cover 2; And the outer end of claw 6 is provided with gradient; The gradient of claw 6 outer ends is identical with the gradient of bellmouth 3, then four claws 6 will draw in each other along fixed disk 5 radial direction, thereby reach the purpose of clamping work pieces 9.As long as main shaft 1 rotation is got up, workpiece 9 just can not get loose, the deficiency that the anchor clamps before having overcome need manpower to clamp; Improved the firmness that workpiece clamps greatly; Make the workpiece machining accuracy satisfy requirement, improved product quality, increased the yield rate of workpiece processing.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
