[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0017] Refer to Figures 1 to 3The utility model provides an embodiment: a chuck automatic back to the original point device, motor 1 has powerful power output, its drive end fixedly connected with the shaft coupling 2, the shaft coupling 2 plays the important role of connection and transmission power, after motor 1 starts, the drive end of motor 1 drives the shaft coupling 2 to rotate, and the shaft coupling 2 further drives the speed reducer 3 to run. The outside fixed connection of speed reducer 3 has the accommodation block 4, and the accommodation block 4 provides stable installation and protection space for speed reducer 3. Speed reducer 3 can reduce the rotating speed and increase the torque, and its drive end is fixedly connected with chuck 5, and speed reducer 3 drives chuck 5 to rotate. The left side of chuck 5 is provided with triangular adapter hole 6, and the triangular adapter hole 6 can be used to connect and adapt with specific components. The outside right side of triangular adapter hole 6 is rotatably connected with a connecting assembly for supporting, and the connecting assembly comprises a mounting plate 7, the right side of the mounting plate 7 is in contact with the left side of the accommodation block 4, and the mounting plate 7 provides stable support for the chuck 5. The inside of the mounting plate 7 is rotatably connected to the outside right end of the chuck 5, so that the chuck 5 can rotate smoothly. The left side of the mounting plate 7 is internally threaded and connected to a plurality of bolts 8, the left side of the accommodation block 4 is provided with a plurality of threaded holes 9, the right end of the bolt 8 is externally threaded and connected to the inside of the threaded hole 9, and the cooperation of the bolt 8 and the threaded hole 9 further enhances the stability of the connection.

[0018] The front bottom end of the connecting assembly is fixedly connected with a carrier plate 10, and the outside of the chuck 5 is rotatably connected to the top end of the carrier plate 10, and the carrier plate 10 provides a support platform for the rotation of the chuck 5. The bottom left side of the carrier plate 10 is fixedly connected with an inductor 11, and the right bottom end of the chuck 5 is fixedly connected with a sensing block 12. When the chuck 5 stops at any position during operation and needs to return to the original position, press the original point button, and the motor 1 starts to work again under the action of the control system, the motor 1 drives the shaft coupling 2 to rotate, the shaft coupling 2 continues to drive the speed reducer 3 to run, and the speed reducer 3 drives the chuck 5 to rotate automatically in the set direction. During the rotation of the chuck 5, the outside of the chuck 5 rotates on the top end of the carrier plate 10, and the sensing block 12 on the right bottom end of the chuck 5 rotates with the chuck 5. When the chuck 5 rotates to the original point, the sensing block 12 coincides with the inductor 11 on the bottom left side of the carrier plate 10, and at this time the inductor 11 sends a signal, and the control system receives the signal and controls the motor 1 to stop working, and the chuck 5 stops rotating, and at this time it is the original position of the chuck 5. At this original position, the chuck 5 can be opened, and the air expansion shaft can be normally taken out or put in, so that the chuck 5 quickly and accurately returns to the original position, reduces the cloth changing time, and improves the operation efficiency of the equipment.

[0019] Working principle: after the motor 1 starts, the driving end of the motor 1 drives the coupling 2 to rotate, and the coupling 2 further drives the speed reducer 3 to operate. The chuck 5 is driven to rotate by the speed reducer 3. When the chuck 5 needs to return to the original position at any stop position during operation, press the original point button, and the motor 1 starts to work again under the action of the control system. The motor 1 drives the coupling 2 to rotate, the coupling 2 continues to drive the speed reducer 3 to operate, and the speed reducer 3 drives the chuck 5 to rotate automatically in the set direction. During the rotation of the chuck 5, the outside of the chuck 5 rotates at the top end of the carrier plate 10, and the sensing block 12 at the right bottom end of the chuck 5 rotates with the chuck 5. When the chuck 5 rotates to the original point, the sensing block 12 coincides with the sensor 11 at the left bottom end of the carrier plate 10, at which time the sensor 11 sends a signal, the control system receives the signal and controls the motor 1 to stop working, and the chuck 5 stops rotating. At this time, it is the original point position of the chuck 5. At this original point position, the chuck 5 can be opened, and the air expansion shaft can be normally taken out or put in, so that the chuck 5 quickly and accurately returns to the original point position, reduces the cloth changing time, and improves the operation efficiency of the equipment.
