Description
Technical field
The utility model relates to a kind of anchor clamps, and especially a kind of anchor clamps of clamping round-disk shape workpiece belong to machining and use the clamp technology field.
Background technology
When machining, for the precision that guarantees that workpiece is processed, and crudy, all can workpiece be fixed on the workbench through anchor clamps.For the workpiece of some disk shapes, shown in accompanying drawing 1, bore several locating holes at the back side of this workpiece 10 if desired; Perhaps end face milling, because the front of this workpiece has groove, and the wall thickness of such workpiece is all little; So it is when clamping is fixed such workpiece, cumbersome.
The utility model content
The utility model purpose is the anchor clamps that a kind of clamping round-disk shape workpiece is provided for the deficiency that overcomes prior art, and it can be easy to setup disc type work the time, guarantees workpiece steadiness and machining accuracy.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of anchor clamps of clamping round-disk shape workpiece comprise base, magnetic suction disc, gear and adjusting nut; Said base is fixed on the workbench; Said magnetic suction disc rotatably is fixed on the base top through connecting axle; On the said base, also be fixed with rotatable regulating shaft on the position parallel with connecting axle; On said connecting axle and the regulating shaft, the below that is positioned at base all is fixed with gear, and two gears are meshing with each other; On the said regulating shaft, be positioned at the top of base, also be fixed with adjusting nut; Said magnetic suction disc is made up of disk cover and disk body, and disk cover is fixed on the disk body top; Said disk body upper surface has around the thread groove that is plate-like; Said disk body is provided with a plurality of claws, and the bottom of each claw is equipped with the latch that matches with thread groove; Have a plurality of draw-in grooves on the circle wall of said disk cover; The size and the claw of said draw-in groove are corresponding, and claw radial direction along disk body in draw-in groove moves.
Preferably, said claw and draw-in groove are four, and all the central shaft of drum body is uniformly distributed with arrangement; Said claw is a rectangle.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The anchor clamps of a kind of clamping round-disk shape workpiece of the utility model scheme, it behind propclip clamping of workpieces, utilizes the suction of magnetic suction disc through thread groove and claw on the disk body of magnetic suction disc; Fix workpiece, after the completion processing, break off the power supply of magnetic suction disc, through adjusting nut; Unclamp claw, take off workpiece, these anchor clamps are inhaled through a folder one; Disc type work is fixed on the workbench firmly, has guaranteed the steadiness of workpiece, improved the machining accuracy and the crudy of workpiece.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is a disc type work to be processed;
Accompanying drawing 2 is the stereogram of the anchor clamps of the utility model clamping round-disk shape workpiece;
Accompanying drawing 3 is the exploded view of the anchor clamps of the utility model clamping round-disk shape workpiece;
Wherein: 1, base; 2, regulating shaft; 3, connecting axle; 4, magnetic suction disc disk body; 5, claw; 6, thread groove; 7, latch; 8, adjusting nut; 9, locating hole; 10, workpiece; 11, disk cover; 12, draw-in groove; 13, gear.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
With the fixing workpiece shown in the accompanying drawing 1 10 is example, adopts the anchor clamps of a kind of clamping round-disk shape workpiece of accompanying drawing 2, the utility model shown in 3, comprises base 1, magnetic suction disc 4, gear 13 and adjusting nut 8; Said base 1 is fixed on the workbench; Said magnetic suction disc 4 rotatably is fixed on base 1 top through connecting axle 3; On the said base 1, also be fixed with rotatable regulating shaft 2 on the position parallel with connecting axle 3; On said connecting axle 3 and the regulating shaft 2, the below that is positioned at base 1 all is fixed with gear 13, and two gears 13 are meshing with each other; On the said regulating shaft 2, be positioned at the top of base 1, also be fixed with adjusting nut 8; Said magnetic suction disc 4 is made up of disk cover 11 and disk body 4, and disk cover 11 is fixed on disk body 4 tops; Said disk body 4 upper surfaces have the thread groove 6 that is plate-like; Said disk body 4 is provided with four claws 5, and the bottom of each claw 5 is equipped with the latch 7 that matches with thread groove 6; Have four draw-in grooves 12 on the circle wall of said disk cover 11; The central shaft of said claw 5 and draw-in groove 12 equal drum bodies 4 is uniformly distributed with arrangement; Said claw 5 is a rectangle; The size of said draw-in groove 12 is corresponding with claw 5, and claw 5 moves along the radial direction of disk body 4 in draw-in groove 12.
During clamping, at first base 1 is fixed on the workbench, then with the groove of workpiece 10 down back-off be placed on the disk cover 11; Rotate adjusting nut 8, drive connecting axle 3 rotations, because the effect of thread groove 6 on the magnetic suction disc disk body 4 and claw 5 through gear 13; Make claw 5 along radially the moving of disk body 4,, open the power supply of magnetic suction disc 4 then until the madial wall of chucking workpiece 10 away from the center of circle of disk body 4; Workpiece 10 is firmly held, workpiece 10 is carried out end face processing and bores locating hole 9 processing, guaranteed the steadiness of workpiece; Improved the machining accuracy and the crudy of workpiece, and clamping rapidly, has accurately improved the working (machining) efficiency of disc type work greatly.
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.
