The specific embodiment

The present invention is described in detail below in conjunction with drawings and Examples.

Consult Fig. 2, Fig. 3 and Fig. 4, a preferred embodiment of the multi-functional tailstock of the present invention comprises a carrier 2, revolving bed 3, power packages 4, stopper group 5, a thimble unit 6, and a grip unit 7.

This carrier 2 has a pair of support 21 that defines a passage 20.

It is interior and also adjacent to support 21 with this that this revolving bed 3 is set in this passage 20.

This power packages 4 have along an axis X pass this revolving bed 3 and fasten in this axle 41, around this axle 41 and with the fixed axle sleeve 42 of this revolving bed 3, be arranged in the support 21 of this carrier 2 and with the oil pressure to support 21 be an oil pressure rotary cylinder 43 of power source, respectively with a pair of

belt pulley

44,45 of this axle sleeve 42, these oil pressure rotary cylinder 43 coaxial rotation, and this belt 46 of cover connection to

belt pulley

44,45.

This stopper group 5 have be installed in these axle sleeve 42 1 ends and and this axle sleeve 42 form interlocks a clip tooth 51, be arranged in this support 21 and be positioned at a clutch tooth 52 of this

support

21 and 51 in this clip tooth along this axis X, and be defined in the adjacent two sides of this

clutch tooth

52 and 21 on this support and distinguish the fuel feeding pressure into and out of two

oil circuits

53,54.

This thimble unit 6 is arranged on this revolving bed 3 one sides, and has a thimble 61 that extends along this axis X.

This grip unit 7 is arranged on this revolving bed 3 opposite sides, and with this axis X is center and this thimble unit 6 angle theta 1 (as Fig. 5) of being separated by, and have a slide rail 71 that extends along vertical this axis X direction, and slide two anchor clamps 72 that close and be subjected to the relative convergent-divergent spacing of oil pressure actuated with this slide rail 71.This angle theta 1 is 90 degree in this preferred embodiment.

Consult Fig. 3, Fig. 4 and Fig. 5, according to aforementioned, when oil pressure is full of this oil circuit 53, this clutch tooth 52 can be moved to an isolated location (as Fig. 3) that breaks away from this clip tooth 51 by oil pressure actuated along this axis X, at this moment, only need to drive this axle sleeve 42 with this oil pressure rotary cylinder 43 by this belt 46 and

aforementioned belt pulley

44,45 and rotate, just can make this axle sleeve 42 is that the center drives this revolving bed 3 around the turn in an angular range, theta 2 of this axle 41 with this axis X.These angular range, theta 2 boundaries are spent to 180 degree in 0.

When oil pressure is full of this oil circuit 54, this clutch tooth 52 can oppositely be moved to an interlock position (as Fig. 4) that engages with this clip tooth 51 by oil pressure actuated along this axis X, at this moment, this clutch tooth 52 can this clip tooth 51 of interlock, makes this axle sleeve 42 be stable at a precalculated position together with this revolving bed 3.In this preferred embodiment, can be stable at a primary importance (0 degree is as Fig. 5) and a second place (90 degree are as Fig. 6) in the aforementioned angular range, theta 2 and one the 3rd position (180 degree are as Fig. 7) by this this revolving bed 3 of stopper group 5 stoppers.

Consult Fig. 4 and Fig. 5, being positioned at the drawing top with cutter (figure does not show) along vertical this axis X direction is example, when this revolving bed 3 is stable at this primary importance, this thimble unit 6 vertically vertically-arranged on this revolving bed 3, and be emerging in outside this

carrier

2,7 along continuous straight runs of this grip unit are collected in this carrier 2 one sides.Whereby, can utilize this thimble 61 to hold the workpiece that general diameter is tiny or length is long (figure does not show) along this axis X direction.

Consult Fig. 4 and Fig. 6, when this revolving bed 3 was stable at this second place, this grip unit 7 vertically vertically-arranged and was emerging in outside this carrier 2 on this revolving

bed

3, and 6 along continuous straight runs in this thimble unit are collected in this carrier 2 opposite sides.Whereby, can utilize the aforementioned anchor clamps 72 of oil pressure actuated to follow this slide rail 71 to contract relatively, put spacing, be used for the erose workpiece of clamping.

Consult Fig. 4, and Fig. 7, when this revolving bed 3 was stable at the 3rd position, this thimble unit 6 be able to vertically be hidden in the passage 20 of this

carrier

2, and 7 along continuous straight runs of this grip unit are emerging in outside this carrier 2.Whereby, can the clamping workpiece rotate 90 degree, make workpiece with different machined surfaces towards cutter, reach the purpose of commutation processing.

According to the above as can be known, multi-functional tailstock of the present invention has following advantage and effect:

The present invention can be by the variation of these revolving bed 3 angles, and the action relationships of this power packages 4 and this stopper group 5, the present invention can be selected for use with this thimble unit 6 hold workpiece, or with these grip unit 7 clamping workpieces, be applicable to that not only general diameter is tiny or length is long or erose workpiece, and can reach the purpose of commutation processing with automated procedures, and then can promote function of use, be applicable to the toolroom machine that need carry out the complicated processing program.
