Abstract
The utility model relates to a special clamp used for the drill press, which comprises a shaft handle and a chuck body. A tap chuck passes through the chuck body, and a clutch sleeve and a combination mechanism with steel ball spring type are connected between the shaft handle and the chuck body. The torque transmitted from the principal shaft of the drill press is transmitted to the chuck body and the tap through the spring, the clutch sleeve and the steel ball. When the threading resistance is larger than the preset torque, the chuck body is stopped by the driven of the tap and the action of the clutch sleeve, and the purpose of the protection of the tap is reached. The clamp can adjust the torque visually and conveniently, and is the safe threading which realizes the quickness and has the action of the pulsating impact.
Description
The utility model relates to a kind of machine tool accessories, specifically a kind of anchor clamps that are suitable for the drilling machine use.
Used safety-type tap holder mostly is the friction-type structure at present, thereby it is to transmit the purpose that moment of torsion is realized protection screw tap, safe tapping by regulating frictional force.Its feature is an applied range, but cost is higher, regulates the not enough intuitive and convenient of frictional force.Therefore, transfer when too much, just break screw tap easily, cause waste when frictional force.
But the purpose of this utility model just provides a kind of safe tap holder that can protect screw tap and intuitive and convenient ground to regulate moment of torsion effectively.
The utility model is achieved in that based on footstalk and collet body, tap chuck is through in the collet body, is connected with clutch cover and steel ball spring formula combining mechanism between footstalk and collet body.Footstalk inserts drill press spindle, and clamping screw tap on the tap chuck rotates by main shaft, drives screw tap and carries out tapping.When tapping runs into obstacle and attacks that blind hole waits situation on earth and when surpassing preset torque, by the effect of clutch cover, make collet body to screw tap partly break away from rotatablely moving of main shaft and stall, thereby protected screw tap.The setting of preset torque realizes by steel ball spring formula combining mechanism.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, footstalk 11 is the major axis shape, and its middle part has screw thread, bottom that outstanding end cap is arranged, and 5 of collet bodies are enclosed within on the bottom end cap of footstalk 11.Tap chuck 1 is through in the collet body 5, and gives fastening by the trip bolt 12 that passes collet body 5 sidewalls.There is flat key 3 to be connected between tap chuck 1 and the collet body 5, screw 4 fixedly connected collet body 5 and flat keys 3.Tap chuck 1 middle part is porose, penetrates for screw tap, and can give fastening by the screw on the edge 2.Between footstalk 11 and collet body 5, also be connected with clutch cover 7 and steel ball spring formula combining mechanism.Steel ball spring formula combining mechanism is made of adjusting nut 10, spring 9 and steel ball 6.Spring 9 is enclosed within on the footstalk 11, and its lower end withstands on the clutch cover 7, and its upper end is by adjusting nut 10 location.Steel ball 6 is between clutch cover 7 and collet body 5.The ball-and-socket of settling steel ball is arranged on the contact-making surface of clutch cover and collet body and steel ball.There is feather key 8 to be connected between clutch cover 7 and the footstalk 11.
The footstalk 11 that inserts drill press spindle rotates main shaft by feather key 8 and passes to clutch cover 7, and make it under the pressure of spring 9 by clutch cover 7 and collet body 5 between on the circumference equally distributed steel ball 6 moment of torsion is passed to collet body 5.Thereby collet body 5 passes to tap chuck 1 to moment of torsion again by flat key 3 and realizes the tapping campaign.When tapping runs into obstacle and surpasses and to give when putting moment of torsion, screw tap and collet body 5 automatic stalls, clutch cover 7 is upwards slippage and compress spring 9 under steel ball 6 effects, and footstalk 11 idle running this moment reach and protect the unlikely purpose that twists off of screw tap.Adjusting nut 10 adjustable springs, 9 pressure and realize preset torque.For realizing reliable clutch, the ball-and-socket on the clutch cover 7 is more shallow than the ball-and-socket on the collet body 5.
Tap holder cost of manufacture provided by the utility model is lower, regulates the moment of torsion intuitive and convenient during use.Especially in the instrument manufacturing, in device fabrication and the single product small serial production, the workpiece material kind is different, under the frequent situation of screw tap specifications vary, can regulate moment of torsion directly perceived, simple and direct, easily, realizes quick, safe tapping.Because the clutch of this tap holder, engagement are pulsed, the counter-rotating of just changeing when screw tap is worked has certain torsional pulse, and the hard and soft action when having imitated hand tapping helps breaking through the bits resistance, makes tapping security and efficient obtain bigger raising.
Claims (4)
1, a kind of tap holder that is suitable for the drilling machine use includes footstalk 11 and collet body 5, and tap chuck 1 is through in the collet body 5, it is characterized in that being connected with between footstalk 11 and collet body 5 clutch cover 7 and steel ball spring formula combining mechanism.
2, tap holder according to claim 1, it is characterized in that steel ball spring formula structure combining mechanism is by adjusting nut 10, spring 9 and steel ball 6 constitute, spring 9 is enclosed within on the footstalk 11, its lower end withstands on the clutch cover 7, its upper end is by adjusting nut 10 location, and steel ball 6 is between clutch cover 7 and collet body 5.
3, tap holder according to claim 1 and 2 is characterized in that having feather key 8 to be connected between clutch cover 7 and the footstalk 11.
