SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a not enough to prior art, and provide a self-adaptation chuck that floats, it presss from both sides the object through unsteady syringe needle clamp, can be fit for the work piece of different shapes, and the clamp force of unsteady syringe needle can be controlled, and it can press from both sides and get breakable work piece.
The technical solution of the utility model is as follows:
the self-adaptive floating chuck comprises an upper chuck and a lower chuck, the upper chuck and the lower chuck have the same structural shape and size, and the upper chuck is opposite to the lower chuck;
the structure of lower chuck is: a floating seat is fixed on the bottom plate, a plurality of cylindrical accommodating spaces are formed in the floating seat, a plug bush hole is formed in the upper end of each accommodating space, the diameter of the plug bush hole is smaller than that of each accommodating space, the plug bush hole and the accommodating spaces are coaxial, and the guide sleeve is plugged in the plug bush hole 2 and is fixedly bonded on the floating seat;
the upper end of the needle head of the floating needle head is spherical, a needle head stop block is formed at the lower end of the floating needle head, the floating needle head is inserted and sleeved in the guide sleeve, and the needle head stop block is positioned in the accommodating space; a stopper ring groove is formed on the needle head stopper, and the first sealing ring is clamped in the stopper ring groove and clamped between the needle head stopper and the inner wall of the accommodating space;
a second sealing ring is clamped between the entity on the floating seat at each accommodating space and the bottom plate, and the second sealing ring is an O-shaped ring;
an air inlet channel is formed on the bottom plate, a plurality of air inlet holes are formed on the bottom plate and communicated with the air inlet channel, and each air inlet hole is communicated with one accommodating space.
The plurality of floating needles are distributed on the floating seat at equal intervals in the transverse direction and the longitudinal direction.
The bottom plate and the floating seat are fixed together through screws.
The air inlet channel is communicated with an air supply nozzle of the air pressure station through a pipeline.
The floating needles are 28 in number, four rows are transversely distributed, and seven rows are longitudinally distributed.
The beneficial effects of the utility model reside in that:
the floating needle head clamps an object, can be suitable for workpieces in different shapes, can control the clamping force of the floating needle head, and can clamp fragile workpieces.

Detailed Description
Example (b): as shown in fig. 1 and 2, the self-adaptive floating chuck comprises an upper chuck 1 and a lower chuck 2, wherein the upper chuck 1 and the lower chuck 2 have the same structural shape and size, and the upper chuck 1 is opposite to the lower chuck 2;
the structure of the lower chuck 2 is: the bottom plate 21 is fixed with a floating seat 22, the floating seat 22 is formed with a plurality of cylindrical accommodating spaces 221, the upper ends of the accommodating spaces 221 are formed with inserting sleeve holes 222, the diameters of the inserting sleeve holes 222 are smaller than the diameter of the accommodating space 221, the inserting sleeve holes 222 and the accommodating space 221 are coaxial, and the guide sleeves 24 are inserted in the inserting sleeve holes 222 and are fixedly bonded on the floating seat 22;
the upper end 231 of the floating needle 23 is spherical, the lower end of the floating needle 23 is formed with a needle stop 232, the floating needle 23 is inserted in the guide sleeve 24, and the needle stop 232 is positioned in the accommodating space 221; a stop block annular groove 2321 is formed on the needle head stop block 232, and the first sealing ring 25 is clamped in the stop block annular groove 2321 and clamped between the needle head stop block 232 and the inner wall of the accommodating space 221;
a second sealing ring 26 is clamped between the entity on the floating seat 22 at each accommodating space 221 and the bottom plate 21, and the second sealing ring 26 is an O-shaped ring;
an air inlet channel 211 is formed on the bottom plate 21, a plurality of air inlet holes 212 are formed on the bottom plate 21 and communicated with the air inlet channel 211, and each air inlet hole 212 is communicated with one accommodating space 221.
The floating needles 23 are distributed on the floating seat 22 at equal intervals in the transverse direction and the longitudinal direction.
The bottom plate 21 and the floating seat 22 are fixed together through screws.
The air inlet channel 211 is communicated with an air supply nozzle of the air pressure station through a pipeline.
The floating needles 23 are 28 in number, four rows are transversely distributed, and seven rows are longitudinally distributed.
The working principle is as follows: when the air inlet channel 211 is inflated through the air pressure station, the floating needle 23 extends out from the guide sleeve 24 to clamp the workpiece, and if the shape of the workpiece is a curved surface, the floating needle 23 can automatically adjust the extension degree along with the curved surface of the workpiece, so that the workpiece is clamped. If the workpiece is a fragile object.
The pressure gauge is arranged on a pipeline communicated with the air inlet channel 211 of the air pressure station, when the pressure of the pressure gauge reaches a certain value, the air pressure station stops supplying air to the air inlet channel 211, so that the pressure of the floating needle head 23 can be controlled, and the workpiece is not broken.
