Abstract
The utility model discloses machining equipment technical field, especially a rotatory anchor clamps are prevented to drilling machine. The chuck and the sheath are improved, the chuck is provided with a groove, an anti-rotation pin is arranged in the groove, and the anti-rotation pin locks the end surface of the workpiece shaft to prevent the workpiece shaft from rotating. One end of the chuck is connected with a locking nut and an adjusting washer, the other end of the chuck is connected with a positioning mandrel, and a clamping nut and an opening washer are arranged on the positioning mandrel; the work piece suit supports more firmly on the location mandrel, can change the chuck position through the adjustment packing ring, and the work piece skew that processing vibrations brought can effectively be prevented to the opening packing ring. In addition, the sheath is hollow structure, leaves the chip groove in the cavity, can control the chip removal direction, prevents iron fillings fish tail work piece surface, further promotes the machining precision. The utility model discloses add man-hour in drilling, effective control drilling direction to prevent that the work piece from rotating, not only promoted machining precision and quality, eliminated the potential safety hazard moreover, the security promotes by a wide margin.
Description
Technical field
The utility model machining equipment technical field, the particularly anti-rotation fixture of a kind of drilling machine.
Background technology
At present, bearing class Workpiece boring is added to man-hour, generally all use chuck clamping bearing class workpiece, this type of cylindrical work needs larger clamping pretightning force ability firm grip, particularly hole the incipient stage, rotary head contacts with surface of the work point, and rotary head there will be the phenomenon of the play that skids, and affects machining accuracy and crudy; When serious, drill bit can force the chuck rotation, and the chuck rotation offset can interrupt drill bit, and broken drill bit jumps out very dangerous, has larger potential safety hazard.
The utility model content
The purpose of this utility model is a kind of reliable and stable, easy to loading and unloading, fixed, chip removal anti-rotation fixture of drilling machine smoothly.
The utility model solves the technical scheme that its technical problem adopts:
The anti-rotation fixture of a kind of drilling machine, comprise chuck and sheath, and the described chuck outside connects sheath, and sheath is provided with fixedly drill bushing, and chuck one end connects locking nut, and the chuck other end connects apotting spindle, and apotting spindle is provided with binding nut; Have groove on described chuck, be provided with anti-rotation pin in groove.
Described sheath is hollow structure, leaves chip area in cavity.
Described apotting spindle is connected with binding nut by open washer.
Also connect and adjust packing ring on described chuck.
Be provided with dog screw between described chuck and sheath.
The utility model will have chuck now and sheath improves, and on described chuck, has groove, is provided with anti-rotation pin in groove, and anti-rotation pin lock clamping of workpieces end axial surface prevents that it from rotating.Chuck one end connects locking nut and adjusts packing ring, and the chuck other end connects apotting spindle, and apotting spindle is provided with binding nut and open washer; Workpiece is sleeved on apotting spindle, supports more firmly, by adjusting packing ring, can change chuck position, and open washer can effectively prevent the workpiece skew that the processing vibrations bring.In addition, sheath is hollow structure, leaves chip area in cavity, can control the chip removal direction, prevents that iron filings from scratching surface of the work, further promotes machining accuracy.The utility model is when Drilling operation, and effective keyhole direction, and prevent the workpiece rotation, not only promoted machining accuracy and quality, and eliminated potential safety hazard, and security significantly promotes.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, anti-rotation pin, 2, chuck, 3, sheath, 4, apotting spindle, 5, open washer, 6, binding nut, 7, fixing drill bushing, 8, dog screw, 9, adjust packing ring, 10, locking nut, 11, workpiece.
The specific embodiment
The anti-rotation fixture of a kind of drilling machine as shown in the figure, comprise chuck 2 and sheath 3, described chuck 2 outsides are connected with sheath 3 by dog screw 8, sheath 3 is provided with fixedly drill bushing 7, chuck 2 one ends connect locking nut 10 and adjust packing ring 9, chuck 2 other ends connect apotting spindle 4, and apotting spindle 4 is provided with binding nut 6 and open washer 5; Have groove on described chuck 2, be provided with anti-rotation pin 1 in groove.Described sheath 3 is hollow structure, leaves chip area 12 in cavity.
During use, first apotting spindle 4 and chuck 2, sheath 3 are stitched together, adjust thickness and the number of packing ring 9 by increase and decrease, adjust chuck 2 and sheath 3 positions and tighten locking nut 10, workpiece 11 is being sleeved on apotting spindle 4, put into open washer 5 and tighten binding nut 6, making anti-rotation pin 1 and the laminating of workpiece spindle end surfaces in chuck 2 grooves, workpiece rotation while preventing from holing.It is surface of the work boring that drill bit passes through fixedly drill bushing 7, the iron filings that boring produces are got rid of along chip area 12, unclamp binding nut 6 after having holed, rotational workpieces 11, again tighten binding nut 6 and just can process other apertures, until complete binding nut 6 and the open washer 5 of unloading of perforate takes off workpiece 11 and complete whole manufacturing procedure.
