First claim

The invention claimed is:

1. An online inflating valve insertion device, comprising:
a frame, a chassis, a lift cylinder, a support A, bearing seats, linear bearings, a mounting plate, guide shafts, a lift shaft, a servomotor A, a synchronous pulley A, a connecting plate, a synchronous belt, a synchronous pulley B, a base, a connecting shaft A, a servomotor B, a shaft sleeve A, a lower end cover, a connecting shaft B, a shaft sleeve B, an oil cylinder, bearings A, end covers, a gland, a bearing B, a chassis, a flange, pins, springs, expanding flaps, a connecting shaft C, a protector, an expanding core, a servomotor C, a lead screw A, a linear guide rail A, a sliding support, a linear guide rail B, a lead screw B, a servomotor D, a support B, an inflating valve, a mechanical clamping jaw, a turning block, a servomotor E, a lead screw C, a turning seat, a mounting rack, a support C and a vision sensor;
wherein the chassis, the support C and the mounting rack are fixed on the frame, the vision sensor is mounted on the support C, the mounting plate is fixed above the chassis by the support A, the bearing seats are fixed on the mounting plate, the lift shaft is mounted on the bearing seats through the linear bearings, two ends of the lift shaft are respectively connected with the connecting plate and an output shaft of the lift cylinder, the servomotor A and the base are fixed on the connecting plate, the shaft sleeve A is mounted on the base through the bearings A and the end covers, the synchronous pulley A is connected with an output shaft of the servomotor A, the synchronous pulley B is connected with the connecting shaft A, and the synchronous belt is respectively connected with the synchronous pulley A and the synchronous pulley B;
the lower end cover, the gland and the chassis are fixed on the shaft sleeve A, the servomotor B is mounted on the lower end cover, the shaft sleeve B is mounted on the shaft sleeve A through the bearing B and the gland, the oil cylinder is fixed in the interior of the shaft sleeve B, an output end of the oil cylinder is connected with the connecting shaft B, the servomotor B is connected with the shaft sleeve B through the connecting shaft B, the expanding core is connected with the shaft sleeve B through the connecting shaft C, the expanding core, the connecting shaft C and the shaft sleeve B are circumferentially locked and cannot relatively rotate, and the connecting shaft C and the shaft sleeve B can relatively axially move; the flange is fixed on the chassis, eight uniformly distributed T-shaped chutes are formed in internal cavities of the flange and the chassis, bottom surfaces of eight expanding flaps are respectively in one-to-one correspondence with the eight T-shaped chutes, the expanding flaps can smoothly and highly precisely slide in the chutes, inner side walls of the expanding flaps are slopes of 15 degrees, and two ends of eight springs are respectively connected with the flange and the eight expanding flaps; side faces of the expanding core are two groups of slopes of 15 degrees in uniform and spaced distribution, the number of the slopes in each group is eight, every two slopes have height difference, and side walls of the upper ends of the two groups of slopes are jointed on a conical surface; under the combined action of the pulling force of the oil cylinder and the elastic force of the springs, when the expanding core is located at the lowest position, side walls of the expanding flaps contact with the conical surface of the expanding core, the servomotor B drives the expanding core to rotate for 22.5 degrees through the connecting shaft B, the shaft sleeve B and the connecting shaft C, and the expanding flaps matching with the slopes can be switched between the slopes and the slopes of the expanding core; the oil cylinder drives the connecting shaft C and the expanding core to move up and down; and due to the slope matching of the expanding flaps and the expanding core, the eight expanding flaps synchronously perform centripetal motion and centrifugal motion in the eight uniformly distributed T-shaped chutes formed in the internal cavities of the flange and the chassis, so that the eight expanding flaps implement high-precision synchronous expansion and shrinkage functions;
the servomotor C and the linear guide rail A are fixed on the mounting rack, the lead screw A is connected with the sliding support and the servomotor C, and the servomotor C can drive the sliding support to move along the linear guide rail A up and down through the lead screw A; the linear guide rail B and the servomotor D are fixed on the sliding support, the lead screw B is connected with the support B and the servomotor D, and the servomotor D can drive the support B to move along the linear guide rail B left and right through the lead screw B; and
the servomotor E and the turning seat are fixed on the support B, the servomotor E is connected with the lead screw C, the mechanical clamping jaw is fixed on the turning block, the mechanical clamping jaw clamps the inflating valve, the servomotor E is connected with the lead screw C, an empty slot is formed in the middle of the bottom surface of the turning seat, the lead screw C passes through the empty slot, two symmetrical T-shaped annular grooves are formed in two sides of the interior of the turning seat, two symmetrical T-shaped annular columns are arranged on the lower end face of the turning block, and the T-shaped annular columns can be inserted into the T-shaped annular grooves; the structure of the middle position of the lower end face of the turning block is annual teeth, and the annular teeth and the lead screw C are meshed; and the servomotor E drives the lead screw C to rotate, and due to the meshing matching between the annular teeth and the lead screw C, the turning block can turn along the centers of the T-shaped annular grooves in the turning seat.

2. The online inflating valve insertion device according to claim 1 , wherein corresponding pin holes are formed in the chassis and the flange, and the positioning pins are respectively connected with the pin holes in the chassis and the flange to ensure assembly precision of the chassis and the flange.
