Abstract

The utility model discloses an electric three-jaw chuck with small tooth difference, belonging to metal-cutting machine tools. The planetary transmission with the small teeth difference of the utility model is composed of an eccentric sleeve [6], a gear [7] and an internal gear [8], satisfying the requirement of the large internal reduction ratio of the electric three-jaw chuck. The utility model has the advantages of simple structure and reliable work.

Description

Few electronic scroll chuck of tooth difference

The few electronic scroll chuck of tooth difference of the utility model belongs to the Metal Cutting Machine Tool instrument.Scroll chuck commonly used all is manual on the engine lathe now, wastes time and energy, and labour intensity was bigger when the workman operated.For improving working conditions and boosting productivity, be that the scroll chuck of power occurs in succession with the Pneumatic hydraulic, but because pneumatic and breathing amount hydraulic pressure scroll chuck claw is less, little and flat-die forging blank can not be used for production lot.

The purpose of this utility model is that will to provide a kind of be the scroll chuck of power with the motor, and its claw breathing amount is with manually scroll chuck is the same.Thereby solved the little and application problem of flat-die forging blank on electric chuck of production lot.Not only alleviated labour intensity but also improved production efficiency.Describe in detail below in conjunction with accompanying drawing:

Fig. 1 is the fundamental diagram that the utility model is installed on lathe.

Fig. 2 is the structure chart of the few tooth difference scroll chuck of the utility model.

The utility model is by motor [1], outer deceleration device [2] (V belt that is generally 1: 2 slows down), Power transmission shaft [3] and few teeth difference scroll chuck [4] form. The few teeth difference scroll chuck is then by chuck shell [5], inclined to one side Heart cover [6], gear [7], internal gear [8], finger [9], driver plate [10], parcel [11] and claw [12] institute Form. Motor of the present utility model [1] and outer deceleration device [2] are contained in the afterbody of lathe, power transmission shaft [3] dress In the spindle hole of lathe, the few teeth difference scroll chuck is contained in the lathe spindle front end, and power is by motor [1], warp Pass to eccentric bushing [6] driven gear [7] by outer deceleration device [2] and power transmission shaft [3] and revolve round the sun, because gear [7] Be meshed with fixing internal gear [8], gear [7] will produce spinning motion, and by finger [9] biography of will moving Give driver plate [10], because the back side of driver plate [10] has the inner cone tooth to be meshed with the bevel gear of parcel [11], dish Silk [11] has and then rotated, and is at last mobile by the screw thread drive claw [12] of parcel, realizes electronic clamping and pine Open. Be the interior speed reducing ratio in of chuck by eccentric bushing [6] to the speed reducing ratio of driver plate [10], when gear [7] number of teeth is 74, the number of teeth of internal gear [8] is 75 o'clock, in-74 then, and then total speed reducing ratio is 148.

Claims

1, a kind of few electronic scroll chuck of tooth difference, it is characterized in that motor [1], outer deceleration device [2], power transmission shaft [3] by being contained in the lathe spindle hole being housed at the lathe spindle afterbody, driving eccentric bushing [6] makes gear [7] produce revolution, because internal gear [8] is fixed, so gear [7] is also at spinning motion, by finger [9] and parcel [11], drive claw [12], realize electronic clamping and unclamp.

2, the described few electronic scroll chuck of tooth difference of a kind of claim 1 is characterized in that it is eccentric bushing [6] that its power is imported other part.

3, the described few electronic scroll chuck of tooth difference of a kind of claim 1 is characterized in that the spinning motion of gear [7] is passed to parcel [11] by finger [9].
