The internal diameter of pipe.
Preferably, the driving structure that the drive mechanism is coordinated using worm gear and worm screw.
The beneficial effect brought using above-mentioned technical proposal is：The first sliding block in the present invention is provided with inclination and supported
Face, can provide facility by workpiece and base-separation for the following process transmission of workpiece.Tilt the arc that seating surface top is set
Depressed part can give workpiece to provide a metastable bottom support, and the rubber antiskid layer that arc-shaped recess portion surface is set can be with
Prevent workpiece from producing relative slip in clamping process.Inclination can be reduced by tilting the polytetrafluorethylecoatings coatings of the bottom surface of seating surface
The frictional force of seating surface and pedestal.Slip-knot can be adjusted flexibly towards angle, rubber suction cups is entered for various clamping faces
Row adjustment.Rubber suction cups is hyperboloid of one sheet shape, and inside and outside two layers of sealant can be formed after workpiece is drawn, blessing is improved steady
It is qualitative.After rubber suction cups draws workpiece, due to the different shape of workpiece surface, partial negative pressure suction pipe can not connect with clamping face
Touch, vacuum also can not be just formed, under the continuous action of air-flow, it is impossible to the cut-off plug formed in the negative pressure absorbing pipe of vacuum and section
Discharge orifice is in close contact, and its intake channel is sealed, the automatic blocking of the negative pressure absorbing pipe of off working state is realized.Work as folder
Hold after end, cut-off plug is separated with throttle orifice in the presence of back-moving spring, and negative pressure absorbing pipe comes back to normal condition.Worm gear
The driving structure coordinated with worm screw can simplify the auxiliary equipment of fixture, be easy to fixture to be arranged in various positions.
