Description

Technical Field

[0001] The utility model relates to the technical field of couplings, and more specifically, to a novel main shaft coupling of a square cutting machine. Background Art

[0002] The spindle coupling of the square opening machine is usually used to connect the spindle and the drive device of the square opening machine so that it can transmit power and maintain synchronous operation. The coupling is usually made of metal materials and can withstand high torque and rotation speed to ensure effective transmission between the spindle and the drive device. The spindle coupling is a device used to connect the machine tool spindle and the drive device. Its main function is to transmit power and maintain synchronous operation between the two. The spindle coupling is often used in the square opening machine.

[0003] Publication number CN214248064U discloses a coupling for a spindle. In view of the current spindle structure, a coupling is often used to connect the transmission structure. However, when in use, since the coupling adopts hard contact, the impact of the piston when it is in place is inevitable every time the tool is loaded and unloaded, which generates a certain axial force, thereby reducing the accuracy and service life of the spindle. By arranging an elastic part in the coupling assembly, buffering is achieved by absorbing the impact mainly and dispersing the impact direction as a supplement, thereby achieving the effect of protecting the spindle.

[0004] During the use of the main shaft coupling, the connection of the coupling is not stable enough and the connection strength is not high. Under long-term and high-intensity use of the coupling, the coupling shrapnel often breaks, which causes a gap between the main roller and the motor, which has a great impact on the processing quality. At the same time, the service life of the coupling is short, and it often needs to be repaired and replaced. Utility Model Content
