Abstract
The utility model relates to the technical field of numerically-controlled machine tool clamps, in particular to an elastic stretching tapping tool handle which mainly comprises a clamp head clamping body and a clamp head body. The clamp head clamping body and the clamp head body are connected through an elastic structure which comprises a large spring, a small spring, a spring washer, a flat pad and an elastic clamp spring. The large spring and the small spring are arranged on the outer surface of a cylinder of the clamp head clamping body. The spring washer is arranged on the front portion of the cylinder of the clamp head clamping body. The flat pad is arranged on the back portion of the cylinder. The elastic clamp spring is connected behind the flat pad. According to the elastic stretching tapping tool handle, the large spring and the small spring are arranged on the outer surface of the cylinder of the clamp head clamping body, during tapping, the small spring can generate retraction force to protect a screw tap, the screw tap is prevented from being broken, during reversing after thread tapping, the large spring can generate expanding force, threads are prevented from being damaged during main shaft reversing, meanwhile, generated action force on the screw tap during main shaft first-time reversing is relieved, damage on the screw tap is lowered, and the service life of the screw tap is prolonged.
Description
Technical field
The utility model relates to numerical control machine tool clamp technical field, is specifically related to a kind of elastic telescopic tapping handle of a knife.
Background technology
Tapping handle of a knife, it is the device that is used for fixing screw tap on Digit Control Machine Tool, existing tapping handle of a knife is mainly comprised of chuck clamping body and clamper main body, chuck clamping body is fixed on clamper main body inside, during use, screw tap is fixed by chuck clamping body, but the tapping handle of a knife of this structure, when with lathe or tapper tapping, whenever the degree of depth has reached setting value, due to inertia or due to the tolerance of apparatus control, easily cause screw tap to be fractureed, this phenomenon attack when blind threaded particularly outstanding, cause screw tap life cycle short, seriously reduced the working (machining) efficiency of Digit Control Machine Tool.
Utility model content
The purpose of this utility model is to provide a kind of elastic telescopic tapping handle of a knife, the problem easily fractureing to solve screw tap that prior art exists.
The utility model is mainly comprised of chuck clamping body and clamper main body, chuck clamping body front end is provided with cylinder, clamper main body inside is provided with the corresponding slot of cylinder with chuck clamping body, the front portion of chuck clamping body is placed in the slot of clamper main body, solving the technical scheme that its technical problem adopts is that chuck clamping body is connected by elastic construction with clamper main body, elastic construction comprises big spring, little spring, spring shim, plain cushion and elastic force jump ring, the cylinder outer surface of chuck clamping body is provided with big spring and little spring, the cylinder front portion of chuck clamping body is provided with spring shim, cylindrical rear portion is provided with plain cushion, after plain cushion, be connected with elastic force jump ring.
Above-mentioned chuck clamping surface is provided with fixing hole, by holding screw, fixes screw tap.
The cylinder front end of above-mentioned chuck clamping body is provided with screwed hole, by fillister head screw is installed, carrys out fastening spring pad.
Compared with prior art, the utility model is by being provided with big spring and little spring at the cylinder outer surface of chuck clamping body, and when tapping, little spring can produce retraction force and protect screw tap, prevents that screw tap from fractureing; While having attacked screw thread reversion, big spring can produce expansionary force, thereby destroys screw thread while preventing main shaft reversion, has also alleviated active force when main shaft reverses for the first time, screw tap being produced simultaneously, reduces the damage to screw tap, extends the service life of screw tap.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of chuck clamping body of the present utility model;
Fig. 3 is the structural representation of clamper main body of the present utility model.
1 chuck clamping body, 2 clamper main bodies, 3 holding screws, 4 elastic force jump rings, 5 plain cushions, 6 big springs, 7 little springs, 8 spring shims, 9 fillister head screws, 11 cylinders, 12 fixing holes, 13, screwed hole, 21 slots in figure.
The specific embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3: a kind of elastic telescopic tapping handle of a knife, mainly by chuck clamping body 1 and clamper main body 2, formed, chuck clamping body 1 front end is provided with cylinder 11, clamper main body 2 inside are provided with the corresponding slot 21 of cylinder 11 with chuck clamping body 1, the front portion of chuck clamping body 1 is placed in the slot 21 of clamper main body 2, chuck clamping body 1 is connected by elastic construction with clamper main body 2, elastic construction comprises big spring 6, little spring 7, spring shim 8, plain cushion 5 and elastic force jump ring 4, cylinder 11 outer surfaces of chuck clamping body 1 are provided with big spring 6 and little spring 7, cylinder 11 front portions of chuck clamping body 1 are provided with spring shim 8, cylinder 11 rear portions are provided with plain cushion 5, plain cushion 5 is connected with elastic force jump ring 4 below, chuck clamping body 1 surface is provided with fixing hole 12, by holding screw 3, fix screw tap, cylinder 11 front ends of chuck clamping body 1 are provided with screwed hole 13, by being installed, fillister head screw 9 carrys out fastening spring pad 8.
During use, by cylinder 11 outer surfaces of chuck clamping body 1, be provided with big spring 6 and little spring 7 is given tapping handle of a knife retractility, when tap is on earth or when machine shaft decline length is excessive, the little spring 7 of cylinder 11 outer surfaces pushes up on spring shim 8, thereby little spring 7 produces certain retraction force and protects screw tap, prevent that screw tap from fractureing; While having attacked screw thread reversion, when the big spring 6 of cylinder 11 outer surfaces withstands on plain cushion 5, big spring 6 can produce certain expansionary force, thereby while preventing main shaft reversion, destroy screw thread, also alleviated active force when main shaft reverses for the first time, screw tap being produced simultaneously, the damage of minimizing to screw tap, the service life of prolongation screw tap.
