The working principle is as follows: when the device is used, a cylindrical blank to be processed is processed and placed on a supporting plate of a Y-shaped structure on a chain of a conveying mechanism 4, the blank is conveyed to the position above the top of a side baffle plate along with the rotation of a roller, then a first motor on a swinging mechanism 2 is started to swing towards the conveying mechanism 4, a second motor on a rotating shaft is started to rotate a base plate 5, a clamping mechanism 10 on the top of the base plate 5 approaches to the blank position on the conveying mechanism 4, when clamping is carried out, a pushing unit in a pushing mechanism 7 in a housing 6 is started, the pushing unit can be driven by any one of an air cylinder, a hydraulic cylinder and a push rod motor to push a push rod 701 towards a cover plate 9, at this time, a first abutting groove 703 on the slope surface of a guide plate 702 on the push rod 701 firstly abuts against a push rod 801 on an abutting mechanism 8 along with one end of the guide plate 702, the first abutting groove 703 pushes the push rod 801 to the side direction of the housing 6, and the second pull rod 803 is hinged to the inner side wall of the housing 6, so that the first pull rod 802 moves towards the cover plate 9, the first pull rod 802 drives one end of the movable plate 901, the movable plate 901 moves the cover plate 9 towards the direction far away from the housing 6, and the clamping mechanism 10 extends into the clamping mechanism from the bottom of the blank;

when the pushing unit is not started, the second spring arranged between the cover plate 9 and the pushing plate 401 pushes the pushing plate 401 towards the housing 6, then the pushing plate 401 pulls the two groups of pull rods 402 towards the housing 6, the pull rods 402 drive the cross rods 403 to move towards the housing 6, the cross rods 403 drive the connecting rods 404 to move, and the connecting rods 404 drive the movable clamping plates 407 to move, so that the two groups of movable clamping plates 407 deflect towards the direction away from each other, and the front parts of the movable clamping plates 407 are opened;

with the further movement of the top rod 701, the push rod 801 moves to the position of the second interference groove 704 along the first interference groove 703, because the second interference groove 704 is parallel to the top rod 701, at this time, the push rod 801 remains relatively stationary when the top rod 701 moves, so that the cover plate 9 remains stationary, the clamping mechanism 10 finishes extending, then the top of the top rod 701 begins to interfere with the push plate 401, and starts to push the push plate 401 away from the substrate 5, the above-mentioned opposite steps are installed, so that the two sets of movable clamping plates 407 move towards the positions close to each other, in order to ensure that the center position of the clamped blank is always kept at the same position, the movable clamping plate 407 and the fixed clamping plate 405 are both arc-shaped structures, the installation groove 406 is located at the side where the two sets of fixed clamping plates 405 are far away from each other, one end of the movable clamping plate 407 close to the fixed, when the contact groove of the movable clamping plate 407 is in contact with the inner side wall of the mounting groove 406 of the fixed clamping plate 405, the movable clamping plate 407 and the fixed clamping plate 405 form a clamping component with a circular arc structure, so that the central position of the blank is always in the same position when the blank is clamped, and then the swinging mechanism 2 conveys the blank to the feeding position of the numerically controlled lathe 1;

during feeding, the pushing unit is started, the ejector rod 701 moves towards the direction of the substrate 5, the opposite steps are carried out, the movable clamping plate 407 is firstly opened, and then the whole clamping mechanism 10 moves towards the housing 6, so that when a department exits, the clamping mechanism 10 interferes with a blank fixed on the numerically controlled lathe 1, and feeding is facilitated;

when the workpiece processed by the numerically controlled lathe 1 is discharged, the workpiece is clamped from the conveying mechanism 4 in the same way;

meanwhile, when the clamping mechanism is used, the clamping degree of the clamping mechanism 10 is adjusted according to the diameter of the blank, the plug board connected with the press 503 is pulled out during adjustment, then the fixed clamp plates 405 are pushed, so that the relative positions of the two groups of fixed clamp plates 405 are adjusted, then the fixed plates 405 are moved to proper positions according to the diameter of the blank, the plug board is inserted, meanwhile, the rotating lantern rings on the sleeves at the bottoms of the cross rods 403 are rotated, so that the length of the telescopic rods extending into the sleeves is adjusted, the length of the pull rods 402 is adjusted, and the blank clamping with different diameters is finally realized;

this design is when carrying out the centre gripping to the work piece, the centre gripping position opens earlier, then contradict from the work piece and stretch into, carry out the centre gripping to the work piece at last, when carrying out the material loading to the work piece, open the clamping part in advance, then contradict from the work piece and stretch out, thereby avoid clamping part and work piece mutual interference collision, protective apparatus and work piece safety, use a drive element to realize pressing from both sides the clamp of work piece simultaneously, the simplification equipment control degree of difficulty, reduce the cable laying degree of difficulty, the unloading operation is gone up to the work piece to the convenience, the efficiency of numerical control lathe processing is improved, reduce operating personnel intensity of labour.
