Referring to fig. 1 to 4, a connection device with an automatic positioning function according to the present invention includes: the driving disc 3 is fixed with an output shaft of the rotating equipment, and the driving disc end cover 7, the semicircular ring 2, the positioning beads 6 and the limiting pin 5 are fixed on the output shaft of the rotating equipment; the driving disc 3 is connected to an output shaft of the motor through a spline and rotates along with the motor; the driving disc end cover 7 is arranged on the driving disc 3 through the two semicircular rings 2, so that the driving disc 3 can be driven to move axially; the positioning balls 6 are arranged in positioning holes in the driving disc 3 and play a role in positioning the driving disc 3 in axial movement; one end of the limiting pin 5 is connected with the driving disc 3, and the other end of the limiting pin is connected with the driving disc end cover 7, so that force transmission between the driving disc 3 and the driving disc end cover 7 is realized.
Specifically, the semicircular ring 2 is fixed on the driving disc end cover 7 through the screw 1, and the right side end face of the semicircular ring 2 and the inner surface of the driving disc end cover 7 are respectively matched with the two end faces of the convex ring on the right side of the driving disc 3 so as to limit the axial distance between the semicircular ring 2 and the driving disc end cover 7 relative to the driving disc 3.
Wherein, the right side bulge loop of the driving disc 3 is provided with a countersunk hole, so that the nut end of the limit pin 5 is sunk into the countersunk hole.
And a threaded hole is formed in the driving disc end cover 7, a through hole is formed in the semicircular ring 2, and a screw rod of the screw 1 is screwed into the threaded hole to complete connection between the semicircular ring 2 and the driving disc end cover 7.
The driving disc 3 is provided with an internal spline and is arranged on the output shaft of the motor in a matched mode through the spline.
The driving disc 3 is provided with a radial through hole, the positioning beads 6 are placed in the hole and in clearance fit with the hole, grease is added for lubrication, when the driving disc end cover 7 moves leftwards, the inner surface inclined plane of the driving disc end cover can push the positioning beads 6 into the hole, a groove and the same kind of inclined plane are formed in a motor shaft connected with the driving disc 3, the positioning beads 6 are squeezed to a groove in the motor shaft by the inner surface inclined plane of the driving disc end cover 7 to complete positioning, the groove in the motor shaft is provided with an inclined plane similar to the inner surface of the driving disc end cover, and the shifting fork 9 drives the whole device to axially move outwards to squeeze the positioning.
