The specific embodiment

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

As shown in Figures 2 and 3, the present invention has the preferred embodiment of the main shaft 100 of built-in revolution cylinder pressure, be installed in board 200 inside, and comprise axle unit 20 that a housing 10, axle be located at these housing 10 inside, one and can drive the rotary cylinder 50 that actuator that this axle unit 20 rotates with respect to this housing 10 30, are arranged on the pressure cylinder unit 40 of these actuator 30 inside and and these actuator 30 sockets.

This housing 10 is installed in these board 200 inside and is hollow tube-shape.

This axle unit 20 extends along an axis L, and has an axle sleeve 21, one and be located in the pull bar 22 in this axle sleeve 21, anchor clamps 23 that are subjected to these pull bar 22 interlocks along this axis L.This axle sleeve 21 has chuck 212, one that a first end 211, one be installed in this first end 211 and this first end 211 opposite the second end 213 and a tube portion 214 that is linked to this second end 213 and is hollow form.This one 214 has two introducing roads 215 that are the L type.These anchor clamps 23 are installed on this chuck 212.

This actuator 30 is linked to this axle sleeve 21 and is hollow tube-shape, and has a belt pulley 31, a central siphon 32 that links vertically with this belt pulley 31, two first pathways 33 and two second pathway, 34 (see figure 4)s that stagger and be provided with described first pathway 33, this belt pulley 31 is hollow form, and has an endoporus 311 that this one 214 of a confession is inserted in, described first pathway 33 be arranged to be separated by 180 the degree, and extend to the endoporus 311 of this belt pulley 31 and be communicated with described introducing road 215 by these central siphon 32 stage casings, described second pathway 34 180 degree of being arranged to be separated by, and extend to the endoporus 311 of this belt pulley 31 by these central siphon 32 stage casings.

This pressure cylinder unit 40 has the airtight piston piece 42 that is set in this cylinder chamber 41 and links with this pull bar 22 of a cylinder chamber 41 that is arranged on 30 of this one 214 and this actuators and, this piston piece 42 separates into one first space 411 and one second space 412 with this cylinder chamber 41, described introducing road 215 is communicated to this first space 411, and described second pathway 34 is communicated to this second space 412.

This rotary cylinder 50 is established for 32 of this central siphons, and has two be arranged to be separated by 180 degree and the first flow 51 that is communicated with described first pathway 33, described introducing road 215, this first space 411 and two 180 second runner, 52 (see figure 4)s of spending and being communicated with described second pathway 34, this second space 412 of being arranged to be separated by.

As shown in Figures 2 and 3, when pressure oil imports this rotary cylinder 50 when inner from described first flow 51, by described first pathway 33, when described introducing road 215 is sent to first space 411 of this cylinder chamber 41, the oily effect meeting that is under pressure of this piston piece 42 is moved towards the left side of Fig. 2 and Fig. 3, the interlock that this pull bar 22 is subjected to this piston piece 42 also can then drive these anchor clamps 23 and clamp along axis L towards moving left.At this moment, the pressure oil that originally is present in this second space 412 can be pushed by piston piece 42, and is discharged by described second pathway 34 (seeing Fig. 4 and Fig. 5).

As Fig. 4 and shown in Figure 5, when pressure oil imports this rotary cylinder 50 when inner from described second runner 52, when being sent to second space 412 of this cylinder chamber 41 by described second pathway 34, the oily effect meeting that is under pressure of this piston piece 42 is moved towards the right side of Fig. 4 and Fig. 5, the interlock that this pull bar 22 is subjected to this piston piece 42 also can then drive these anchor clamps 23 and unclamp along axis L towards moving right.At this moment, the pressure oil that originally is present in this first space 411 can be pushed by piston piece 42, and is discharged by described first pathway 33 (seeing Fig. 2 and Fig. 3).

Therefore, the present invention has the main shaft 100 of built-in revolution cylinder pressure, utilize this pressure cylinder unit 40 can control the action that these anchor clamps 23 produce folder or open, utilize this rotary cylinder 50 and this central siphon 32 to rotate socket, can make the pipeline of discharge pressure oil obtain the location, and ensconce belt pulley 31 inside of this actuator 30 in this pressure cylinder unit 40, make that these main shaft 100 entire length are reduced, existing main shaft compared to Fig. 1, the main shaft application that the present invention has a built-in revolution cylinder pressure is on processing machine the time, can reduce the head length of this processing machine,, also can all diminish because of the head length of two subtend settings even be applied to have the processing machine of two-shipper head, and do not hinder operability, the base volume of toolroom machine also can reduce integral miniaturization relatively, low cost of manufacture can reach purpose of the present invention really.
