Further, described positioner comprises be fixedly connected the first locating piece on the first fixed disk and the second fixed block.
Further, described guider comprises be fixedly connected the first guide pad on the first fixed disk and the second guide pad.
Preferably, the internal diameter of described cylinder is 80mm.
Preferably, described cross bar and the first fixed disk pin joint to the distance of described cross bar and push rod pin joint be about 1/3 described cross bar and the first fixed disk pin joint to the distance of the pin joint of the push rod of described cross bar and cylinder.
Further, the protection ring be sleeved on the first fixed disk and the second fixed disk is also comprised.
After adopting technique scheme, there is following beneficial effect:
(1) self-centering and Automatic-clamping can be realized;
(2) reduce manufacturing procedure, improve working (machining) efficiency;
(3) ensure the stability of crudy, improve crudy.
Accompanying drawing explanation

In figure: 1. the first fixed disk; 2. connector; 3. the second fixed disk; 4. cylinder; 5. cross bar; 6. push rod; 7. guider; 7-1. first guide pad; 7-2. second guide pad; 8. workpiece; 9. positioner; 9-1. first locating piece; 9-2. second fixed block; 10. protection ring.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
As depicted in figs. 1 and 2: a kind of lathe air spider, comprise the first fixed disk 1 and the second fixed disk 3, described first fixed disk 1 and the multiple connector 2 of the second fixed disk 3 are fixedly connected and are parallel to each other, and described second fixed disk 3 is fixedly connected cylinder 4; Described first fixed disk 1 is provided with for the positioner 9 of positioning workpieces 8 and the guider 7 for the push rod 6 that leads; Described positioner 9 can make the center in processed hole on workpiece 8 overlap with the centre of gyration of lathe spindle; Be provided with mother-son groove between described guider 7 and push rod 6, push rod 6 can be made to move along guider 7 linear reciprocation, realize the pine folder of workpiece 8; The end of described push rod 6 and one end of cross bar 5 hinged, the other end of described cross bar 5 and the push rod of cylinder 4 hinged, described cross bar 5 by bolt and the first fixed disk 1 hinged.
Further, described positioner 9 comprises the first locating piece 9-1 on the first fixed disk 1 and the second fixed block 9-2 that is fixedly connected.Because workpiece 8 is non-cylindrical revolving bodies, be bolted on the first locating piece 9-1 on the first fixed disk 1 and the second locating piece 9-2 and complete location in two dimensions respectively, ensure that the center in the processed hole on workpiece 8 and the lathe spindle centre of gyration overlap completely.
Further, for ensureing that push rod 6 useful effect is on workpiece 8, described guider 7 comprises the first guide pad 7-1 on the first fixed disk 1 and the second guide pad 7-2 that is fixedly connected.
Preferably, for ensureing the compact and sufficient clamping force of structure of the present invention, the internal diameter of described cylinder 4 is 80mm.
Preferably, in order to amplify the driving force that cylinder 4 exports, ensure the clamping effect of workpiece 8, described cross bar 5 and the first fixed disk pin joint to the distance of described cross bar 5 and push rod 6 pin joint be about 1/3 described cross bar 5 and the first fixed disk pin joint to the distance of the pin joint of the push rod of described cross bar 5 and cylinder 4.
Further, in order to improve the present invention's security in use, the present invention also comprises the protection ring 10 be sleeved on the first fixed disk 1 and the second fixed disk 3.
Principle of the present invention: cylinder 4 is connected by the compressed air hose of sealing device with lathe spindle center.Lathe air spider is fixed on the main shaft of lathe by the scroll chuck of lathe.When lathe air spider works, compressed air enters lathe spindle by tracheae, then enters in cylinder 4, and cylinder 4 Work Promote push rod 6 moves upward, and according to lever principle, the other end of cross bar 5 moves downward, clamping work pieces 8.When after completion of processing, the reversal valve work of cylinder 4, makes to move in the other direction to unclamp workpiece 8.
