Description

The compound clamping device of lathe
Technical field
The invention belongs to the jig field, specifically, relate to a kind of clamping device for fixation workpiece, more particularly, relate to the compound clamping device of a kind of lathe.
Background technology
In machine industry, lathe is widely used in processing all kinds of parts, need to reliably locate workpiece man-hour adding.Larger workpiece processing, generally can directly on platen, by adjusting fixture, realize positioning and clamping to single-piece, small lot, workload, the position of part is determined in the setting that by machining coordinate is then; For the part that certain batch is arranged, need by selecting relevant special fixture to reduce labour intensity, reduce part processing non-cutting time, enhancing productivity.But using special fixture to add man-hour, usually to change special fixture, reduce operating efficiency.For enterprise, in order to reduce cost, the versatility of fixture also should be taken into account.Therefore, the clamping device that necessary design makes new advances, to be applied in fixture.
Summary of the invention
The labour intensity caused for existing clamping device is large, part is processed length non-cutting time, special fixture causes the problems such as versatility is not high, the invention provides the compound clamping device of a kind of lathe.
For addressing the above problem, the present invention adopts following technical scheme.
The compound clamping device of a kind of lathe, comprise slide rail, large adjusting screw(rod), movable block, large clamp, the minor adjustment screw rod, fixed block and little clamp, the upper end of slide rail is stuck on the recessed edge in movable block lower end, described large adjusting screw(rod) is meshed with movable block, described large clamp lower end is pressed on the recessed edge in upper end of movable block, the upper end of large clamp is provided with groove, the vertical direction cross section on groove top is rectangle, the groove bottom is dovetail groove, described fixed block is fixed on the groove side of large clamp, the upper end of described little clamp flushes with the groove upper end of large clamp, the lower end of little clamp embeds in the dovetail groove of large clamp groove lower end, described minor adjustment screw rod is meshed with fixed block, one end and the little clamp of minor adjustment screw rod are connected.
Described slide rail, movable block, large clamp, minor adjustment screw rod, fixed block and little clamp are all two parts, symmetrical.
Than prior art, beneficial effect of the present invention is:
(1) the present invention is provided with large clamp and little clamp, can use separately, to be applicable to the clamping of different size workpiece, has increased the versatility of special fixture.
(2) the present invention is provided with large clamp and little clamp, can successively use separately, changes fixture while having avoided processing work, has reduced labour intensity, has reduced part and has processed non-cutting time.
(3) the present invention is provided with large clamp and little clamp, can use simultaneously, adds the rigidity in man-hour to increase workpiece, reduces machining deformation, and machining accuracy is provided.
(4) the present invention is simple in structure, reasonable in design, is easy to manufacture.
The accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is the cutaway view of Fig. 1 along the A-A line;
Fig. 3 is top view of the present invention.
In figure: 1-slide rail, 2-large adjusting screw(rod), 3-movable block, 4-large clamp, 5-minor adjustment screw rod, 6-fixed block, 7-little clamp.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention.
As Fig. 1, Fig. 2, shown in Fig. 3, the compound clamping device of lathe comprises slide rail 1, large adjusting screw(rod) 2, movable block 3, large clamp 4, minor adjustment screw rod 5, fixed block 6 and little clamp 7, the upper end of slide rail 1 is stuck on the movable block 3 recessed edge in lower end, described large adjusting screw(rod) 2 is meshed with movable block 3, described large clamp 4 lower ends are pressed on the recessed edge in upper end of movable block 3, the upper end of large clamp 4 is provided with groove, the vertical direction cross section on groove top is rectangle, the groove bottom is dovetail groove, described fixed block 6 is fixed on the groove side of large clamp 4, the upper end of described little clamp 7 flushes with the groove upper end of large clamp 4, the lower end of little clamp 7 embeds in the dovetail groove of large clamp 4 groove lower ends, described minor adjustment screw rod 5 is meshed with fixed block 6, one end and the little clamp 7 of minor adjustment screw rod 5 are connected.Described slide rail 1, movable block 3, large clamp 4, minor adjustment screw rod 5, fixed block 6 and little clamp 7 are all two parts, symmetrical.
In processing dimension, during certain workpiece, rotation minor adjustment screw rod 5, make little clamp 7 away from the fixture center; Rotate large adjusting screw(rod) 2, movable block 3, under the effect of large adjusting screw(rod) 2, makes slide rail 1 slide to centre, thereby drives moving and complete and clamping action of large clamp 4, and now the clamping area of large clamp 4 matches with side surface of workpiece, completes location.Otherwise the large adjusting screw(rod) 2 of counter-rotating can loosen workpiece.
When the certain workpiece of the another kind of size of processing, rotate large adjusting screw(rod) 2, movable block 3, under the effect of large adjusting screw(rod) 2, makes slide rail 1 slide to centre, thus drive large clamp 4 move to appropriate location to the fixture center; Rotate minor adjustment screw rod 5, little clamp 7 moves to the fixture center under the effect of minor adjustment screw rod 5 again, and the clamping area of now little clamp 7 matches with side surface of workpiece, thereby completes location.Otherwise the large adjusting screw(rod) 2 of counter-rotating and minor adjustment screw rod 5 can loosen workpiece.
