Further, described positioner comprises the first locating piece and the second fixed block being fixedly connected on the first fixed disk.
Further, described guider comprises the first guide pad and the second guide pad being fixedly connected on the first fixed disk.
Preferably, the internal diameter of described cylinder is 80mm.
Preferably, described cross bar and the first fixed disk pin joint are 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 to the distance of described cross bar and push rod pin joint.
Further, also comprise the protection ring being sleeved on the first fixed disk and the second fixed disk.
Adopt after technique scheme, there is following beneficial effect:
(1) can realize self-centering and Automatic-clamping;
(2) reduce manufacturing procedure, improve working (machining) efficiency;
(3) guarantee the stability of crudy, improve crudy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of protection ring.
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. the first guide pad; 7-2. the second guide pad; 8. workpiece; 9. positioner; 9-1. the first locating piece; 9-2. the second fixed block; 10. protection ring.
The specific embodiment
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 the first fixed disk 1 and a plurality of connectors 2 of the second fixed disk 3 use are fixedly connected and are parallel to each other, and cylinder 4 is fixedly connected on described the second fixed disk 3; Described the first fixed disk 1 is provided with for the positioner 9 of positioning workpieces 8 with for the guider 7 of the push rod 6 that leads; Described positioner 9 can make the processed Kong center on workpiece 8 overlap with the centre of gyration of lathe spindle; Between described guider 7 and push rod 6, be provided with mother-son groove, can make push rod 6 move along guider 7 linear reciprocation, realize the pine folder of workpiece 8; One end of the end of described push rod 6 and cross bar 5 is hinged, and the push rod of the other end of described cross bar 5 and cylinder 4 is hinged, and described cross bar 5 is hinged by bolt and the first fixed disk 1.
Further, described positioner 9 comprises the first locating piece 9-1 and the second fixed block 9-2 being fixedly connected on the first fixed disk 1.Because workpiece 8 is non-cylinder revolving bodies, the first locating piece 9-1 and the second locating piece 9-2 that are bolted on the first fixed disk 1 complete respectively two location in dimension, guarantee that processed Kong center and the lathe spindle centre of gyration on workpiece 8 overlaps completely.
Further, for guaranteeing that push rod 6 useful effects are on workpiece 8, described guider 7 comprises the first guide pad 7-1 and the second guide pad 7-2 being fixedly connected on the first fixed disk 1.
Preferably, for guaranteeing compactness and the 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 of cylinder 4 outputs, guarantee the clamping effect of workpiece 8, described cross bar 5 and the first fixed disk pin joint are about the distance of the pin joint of the push rod that 1/3 described cross bar 5 and the first fixed disk pin joint arrive described cross bar 5 and cylinder 4 to the distance of described cross bar 5 and push rod 6 pin joints.
Further, in order to improve the present invention's security in use, the present invention also comprises the protection ring 10 being sleeved on the first fixed disk 1 and the second fixed disk 3.
Principle of the present invention: cylinder 4 is connected with the compressed air hose at lathe spindle center by sealing device.Lathe air spider is fixed on the main shaft of lathe by the scroll chuck of lathe.When lathe air spider is worked, compressed air enters lathe spindle by tracheae, then enters in cylinder 4, and cylinder 4 Work Promote push rods 6 move upward, and according to lever principle, the other end of cross bar 5 moves downward, clamping work pieces 8.After completion of processing, the reversal valve work of cylinder 4, makes the mobile workpiece 8 that unclamps in the other direction.
