Summary of the invention
The technical problem to be solved in the present invention is to provide the applicable screw-driving apparatus of a kind of lathe.
In order to solve the problems of the technologies described above, the invention provides a kind of screw-driving apparatus, comprise bracing frame, axle, put charging basket, torsion spring, location-plate, locating dowel and turn screw, in support frame as described above, be provided with axis hole and feeding chute, axle is arranged in axis hole, bracing frame top be fixedly connected with location-plate, bracing frame and location-plate are flexibly connected by locating dowel, location-plate top is provided with torsion spring, torsion spring set is on axle, torsion spring top is provided with puts charging basket, put charging basket center and be provided with through hole, putting charging basket is enclosed within on axle by through hole, put charging basket one end and be also provided with material-dropping hole, material-dropping hole and feeding chute are communicated with by siphunculus, the upper end of axle is provided with shaft coupling, the bottom of axle is provided with drill bit.
Adopt the screw-driving apparatus tool of technique scheme to have the following advantages: screw-driving apparatus is connected with lathe by the shaft coupling of shaft end, screw placement is putting in charging basket, and enters in feeding chute by material-dropping hole, and screw slides to lower end, by turn screw, processes.
Further, between described torsion spring and location-plate, be also provided with rotating limit device.Control the slewing area of torsion spring.
Further, described basket is provided with the first caudal furca; With the first caudal furca in the same way, location-plate is provided with the second caudal furca, the free end of described the first caudal furca and the second caudal furca can horizontal direction clamp mutually.Prevent that basket and location-plate are in rotary moving.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the new screw-driving apparatus of this practicality.
The specific embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
As shown in Figure 1, the invention provides a kind of screw-driving apparatus, comprise bracing frame 1, axle 2, put charging basket 3, torsion spring 4, location-plate 5, locating dowel 6 and turn screw 7, in bracing frame 1, be provided with axle 2 holes and feeding chute 8, axle 2 is arranged in axle 2 holes, bracing frame 1 top be fixedly connected with location-plate 5, bracing frame 1 and location-plate 5 are flexibly connected by locating dowel 6, location-plate 5 tops are provided with torsion spring 4, torsion spring 4 is enclosed within on axle 2, torsion spring 4 tops are provided with puts charging basket 3, put charging basket 3 centers and be provided with through hole, putting charging basket 3 is enclosed within on axle 2 by through hole, put charging basket 3 one end and be also provided with material-dropping hole, material-dropping hole and feeding chute 8 are communicated with by siphunculus 9, the upper end of axle 2 is provided with shaft coupling 10, the bottom of axle 2 is provided with turn screw 7.Between torsion spring 4 and location-plate 5, be also provided with torque limiting device.Basket is provided with the first caudal furca; With the first caudal furca in the same way, location-plate 5 is provided with the second caudal furca, the free end of described the first caudal furca and the second caudal furca can horizontal direction clamp mutually.Axle is connected with pressure sensor, thereby can avoid the screw thread of the excessive damage of pressure pin, also can avoid damaging assembling workpiece.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
