End cap 228 is incorporated in the upper end of outer tube 222, is equipped with o-ring 230 inside it.O-ring 230 is close to inner tube 234 Around, to keep air-tightness.Inner tube 234 runs through the center for being incorporated in end cap 228.Inner tube 234 is in hollow cylindrical shape, It is combined with attachment cap 242 in the upper end that it is opened, lower end is combined with upper taper tip 264.Including being respectively formed The upper end of pipe 234 and the upper taper tip 238 of lower end and lower taper tip 240, attachment cap 240 and top Cone point 264 is firmly bonded in inner tube 234, so as to integrally be risen or fallen.

The center of inner tube 234 is formed with mesoporous 236.The air of high pressure is supplied to mesoporous 236, makes inner tube 234 logical as a result, The pressure based on air is crossed to be risen.

The lower end of inner tube 234 is combined with upper taper tip 264.The connector 270 at upper taper tip 264 is located at interior The inside of pipe 234, rest part are projected into the outside of inner tube 234 and are located at the inside of outer tube 222.Upper taper tip 264 Around be equipped with external o-ring 268, external o-ring 268 connects with the inner peripheral surface of outer tube 222 and keeps air-tightness, also, leads to Frictional force is crossed to play the role of preventing inner tube 234 from flying up.

The lower end edge at upper taper tip 264 is formed with top cone 274.Due to top cone 274, upper taper Tip 264, which has, more tends to lower end diameter with regard to smaller truncated cone shape.Conical clutch part 260 can be located at upper taper point Around end 274.

Clutch pipe 254 runs through the center for being incorporated in upper taper tip 264.Due to through hole 224, it is incorporated into clutch pipe Space between the internal piston 250 and upper taper tip 264 of 254 upper ends is in atmospheric pressure state.

It is formed in be equipped in the space in 264 center of upper taper tip and places step 272.Elastic component 285, which is located at, to be placed On step 272.As shown in figure 9, elastic component 285 provides the power for increase internal piston 250.Elastic component 285 can be spiral shell Spring or elastic rubber etc. are revolved, the present invention is not limited by the shape of elastic component and material.

The inside at upper taper tip 264 is equipped with internal o-ring 266.The internal contact of o-ring 266 is through upper taper point Around the clutch pipe 254 in 264 center of end, to keep air-tightness.

Clutch pipe 254 through 264 center of upper taper tip has mesoporous 256, is equivalent to the circle with specific length Column.The upper end and lower end of clutch pipe 254 have open structure.Therefore, clutch pipe is passed through by the air that gas nozzle 280 supplies 254 flow into the mesoporous 236 of inner tube 234.

The upper end of clutch pipe 254 is combined with internal piston 250, and lower end is combined with lower taper tip 258.Also, Clutch pipe 254 is inserted into a manner of it can move up and down relative to upper taper tip 264.Therefore, clutch pipe 254 plays The effect for the power on internal piston will be applied to being transmitted on lower taper tip 258.That is, when downward pressure F2 passes through air When acting on internal piston 250, internal piston 250 and clutch pipe 254 decline relative to upper taper tip 264, thus make Lower taper tip 258 also declines.In addition, not supplying air and only being acted on based on upwarding pressure for elastic component 285 When internal piston 250, internal piston 250 and clutch pipe 254 rise relative to upper taper tip 264, thus make lower cone Shape tip 258 also rises.

250 secure bond of internal piston is located at the inside of inner tube 234 in the upper end of clutch pipe 254.Inner tube 250 Around be equipped with o-ring 252, so as to keep air-tightness.In addition, the lower surface of internal piston 250 is by 285 bullet of elastic component Property is pressurizeed upwards.By moving up and down for internal piston 250, conical clutch part 260 is formed or released for 222 inner peripheral surface of outer tube Pressure.Also, when inner tube 234 rises, internal piston 250 moves down and to elastic component 285 and upper taper Tip 264 is pressurizeed downwards, and therefore, inner tube 234 will not fly up but gently rise.

258 secure bond of lower taper tip is formed integrally and upper and lower in the lower end of clutch pipe 254 with clutch pipe 254 It is mobile.Subtle gap is formed between lower taper tip 258 and the inner peripheral surface of outer tube 222.Therefore, lower taper tip 258 can move up and down without let or hindrance in the inside of outer tube 222.In addition, shape on the surrounding face at lower taper tip 258 At there is a lower part cone 259, thus there is truncated cone shape.Lower part cone 259 and top cone 274 symmetrically configure. And conical clutch part 260 is configured with around top cone 274 and lower taper tip 259.

Conical clutch part 260 is in ring (ring) shape, and cutting section 262 is formed within the scope of the whole length of one side. By cutting section 262, the outer diameter of conical clutch part 260 can become larger or become smaller, and the inner peripheral surface of conical clutch part 260 has simultaneously Corresponding to top cone 274 and the pyramidal structure of lower part cone 259.

Based on the spacing between upper taper tip 264 and lower taper tip 258, the outer diameter of conical clutch part 260 becomes (gap of cutting section 262 becomes larger) or become smaller (gap of cutting section 262 becomes smaller) greatly.When the outer diameter of conical clutch part 260 becomes When big, around face squeeze the inner peripheral surface of outer tube 222, thus, it is possible to fixed inner tube 234 and upper taper tip 264 relative to The height of outer tube 222.In addition, when the outer diameter of conical clutch part 260 becomes smaller, around face will not squeeze the inner circumferential of outer tube 222 Face, thus inner tube 234 and upper taper tip 264 can be moved up and down relative to outer tube 222.

Elastic component 285 is located at the inside at upper taper tip 264, and its center is through there is clutch pipe 254.Elastic structure For the lower end of part 285 on the placement step 272 at upper taper tip 264, upper end contacts the following table of internal piston 250 Face.The upward pressurization inner tube 250 of elastic component 285, makes it away from upper taper tip 264.As a result, lower taper tip 258 with Spacing between upper taper tip 274 becomes smaller, and is imitated by the chock at upper taper tip 274 and lower taper tip 259 Fruit makes the outer diameter of conical clutch part 260 become larger.Since the outer diameter of conical clutch part 260 becomes larger, it is fixed inside outer tube 222 Height, therefore, also fix height of the inner tube 234 inside outer tube 222.Certainly, when supplying air, the power based on air is big In the fixed force (containing frictional force) based on elastic component 285, therefore even if pressing in the presence of the elasticity based on elastic component 286, Increase inner tube 234.

When air is supplied to cylinder 221, and inner tube 234 is made to increase because of power F1, the pressure F2 downward due to air (< F1 internal piston 250) is acted on, makes internal piston 250 by power directed downwardly.At this point, acting on the power F2 on internal piston 250 Upwarding pressure based on elastic component 285 can be greater than.Therefore, internal piston 250 declines, under being connected with clutch pipe 254 Portion's cone point 258 also simultaneously declines, and expands the spacing of itself and upper taper tip 264.As shown in Figure 10, work as lower cone When spacing between shape tip 258 and upper taper tip 264 becomes larger, the diameter of conical clutch part 260 becomes smaller (cutting section 262 Shrink), so that the pressure for 222 inner peripheral surface of outer tube is released, thus it enables that inner tube 234 rises.

When air is not supplied to cylinder 221, due to eliminating the pressure based on air, inner tube 234 can decline.This When, the pressure based on air does not act on internal piston 250, is only had an effect based on upwarding pressure for elastic component 285. Therefore, inner tube 250 rises relative to upper taper tip 264, and the lower taper tip being connected on clutch pipe 254 258 rise, to reduce its spacing with upper taper tip 264 (referring to Fig. 9).

When the spacing between upper taper tip 264 and lower taper tip 258 becomes smaller, the taper that falls between The cutting section 262 of clutch part 260 is unfolded, and outer diameter becomes larger.When the outer diameter of conical clutch part 260 becomes larger, around face squeeze The inner peripheral surface of outer tube 222, thus height of the stationary phase for outer tube 222.By the height of fixed taper clutch part 260, also can Enough fixed height of the inner tube 234 relative to outer tube 222.

In this way, when supplying air, making internal piston in the cylinder 221 for the clamping device 100 that the present embodiment is related to 250 and lower taper tip 258 decline, and release the lock state of conical clutch part 260, for inner tube 234 or more or Pressurization downwards less, thus inner tube 234 will not fly up but gently rise.In addition, in cylinder 221, it is empty when removing When gas, based on the elastic force of elastic component 285, conical clutch part 260 increases its outer diameter by chock effect and is close to outer tube 222 Inner peripheral surface, thus the height of fixed inner tube 234.Therefore, it can prevent inner tube 234 from declining suddenly.
