The lifting ring nut is a part that tightly connects the mechanical equipment. It can be connected together through the inner thread, the lifting ring nut and the screw of the same specification. Lifting ring nuts are often used in conjunction with externally threaded columns to lift various equipment, such as molds, chassis, motors, etc.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the slotting device 4 includes a motor 41 and a motor 43, the cutting wheel 42 is fixedly arranged at the output end of the motor 41, and the motor 41 drives the cutting wheel 42 to rotate to open the screw. slot, the motor 43 is fixedly arranged on the workbench 1, the motor 41 is arranged on the motor 43, a track 47 is arranged between the motor 41 and the motor 43, the motor 41 can reciprocate through the track 47, and when the screw is slotted, the motor 41 drives the cutting wheel 42 to move in the direction of the screw. When the slotting is finished, the motor 41 drives the cutting wheel 42 to retract. The fixed wheel 48 is arranged at the output end of the motor 43. The fixed wheel 48 is located directly below the cutting wheel 42. The surface of the middle screw is in contact, and the motor 43 drives the fixed wheel 48 to rotate to grind and polish the surface of the slotted screw to make the surface smooth. Preferably, the direction of rotation of the cutting wheel 42 and the fixed wheel 57 is opposite.
The traveling plate can be driven by the traveling cylinder to move from the lower end of the circlip sleeve rod to the lower ends of the two probes of the circlip tightening mechanism; after the two probes tighten the circlip, the traveling plate can be moved in the traveling cylinder. The tightening mechanism moves down under the drive of the lifting cylinder, the probe installs the tightened circlip in the workpiece, and then retracts the probe upward.
