Preferably, the air pipe joint is arranged in the small hole in the middle of the clamp positioning plate, and one end of the air pipe joint extends out of the clamp positioning plate.

Preferably, a sealing ring is installed at the bottom of the clamp exchange plate.

Compared with the prior art, the beneficial effects of the utility model are as follows:

this dysmorphism nut anchor clamps puts into the circular recess with the processing material to rock gently and make it fall into cylinder change-over valve from the material hole, because of cylinder change-over valve and processing material produce an airtight space under the isolation of sealing washer, when cylinder change-over valve started working through the change-over valve that the trachea connects, the gas in the airtight space of suction makes it become vacuum state, so forms the pressure differential with peripheral machined surface, consequently plays the ability of adsorbing, snatching the work piece under the effect of pressure differential.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a special-shaped nut fixture comprises a fixture base plate 1, cylinder fixing blocks 2 are installed at two ends of the fixture base plate 1, a cylinder 3 is installed at the upper end of the cylinder fixing block 2, a positioning plate pillar 4 is installed at the middle of the fixture base plate 1, a fixture positioning plate 5 is installed at the upper end of the positioning plate pillar 4, a positioning pin 6 and a fixture exchange plate 7 are arranged on the fixture positioning plate 5, wherein the positioning pin 6 is installed at two ends of the fixture positioning plate 5, pin holes 8 are formed at two ends of the fixture exchange plate 7, the pin holes 8 are correspondingly matched with the positioning pin 6, the fixture exchange plate 7 is placed on the fixture positioning plate 5, the positioning pin 6 is embedded in the pin holes 8, a gas pipe connector 51 is installed in a small hole in the middle of the fixture positioning plate 5, one end of the gas pipe connector 51 extends out of the fixture positioning plate 5 and is connected with a, material holes 72 are uniformly distributed in the circular groove 71, the material holes 72 are communicated with an air suction cavity formed by the clamp positioning plate 5 and the clamp exchange plate 7, a machining material is placed in the circular groove 71 and gently shaken to fall onto the cylinder conversion valve from the material holes 72, and a sealing ring 10 is mounted at the bottom of the clamp exchange plate 7, so that a closed space is formed by the cylinder conversion valve and the machining material under the isolation of the sealing ring 10, a pressing block 9 is connected to an air rod of the cylinder 3, and one end of the pressing block 9 extends onto the clamp exchange plate 7 and is in contact connection with the pressing block 9; the cylinder pulling valve of the cylinder 3 is opened, so that the pressing block 9 is driven to compress the clamp exchanging plate 7.
