Service HotlineIn the process of completing the adjustment of the position of the object, the nut will move up and down with the entry and exit of the screw, and it cannot make a sound for people to perceive, and it cannot provide people with a position change distance through the action of rotation.
Among the mold parts used in the can manufacturing industry, some product inner holes need to be processed with stop slots after heat treatment. The inner hole diameter of the product is φ28mm, the width of the slot is about 1.3mm, and the size and shape of the outer end face of the slot adjacent to the orifice The tolerance requirements are very strict, generally within the range of 0.02mm. If the CNC machine tool is used for cutting, the blade loss is very serious because the groove width is too narrow; if the inner hole grinding is used, there is no ready-made grinder and grinding wheel.
In another embodiment of Guangdong Yueluo Hardware Industrial Co., Ltd., the conveying device 3 includes a motor 31 and a circular rotating disk 34, the motor 31 drives the circular rotating disk 34 to rotate, and the circular rotating disk 34 is evenly provided with screws in the circumferential direction. The matching screw accommodating hole 35, the screw enters the screw accommodating hole 35, the motor 31 drives the circular rotating plate 34 to rotate, so that the screw is first slotted by the cutting wheel 42, and then polished by the fixing wheel 48, and the screw is in the screw accommodating hole 35. It is fixed, which is more secure and reliable during the slotting process. Preferably, the circular rotating disk 34 includes a circular rotating disk 32 and a sector-shaped fixed disk 33. The circular rotating disk 32 is evenly provided with screw receiving recesses matching the screws in the circumferential direction, and the recesses and the sector-shaped fixed disk 33 are formed with the screws The matching screw receiving holes face the cutting wheel 42 and the fixing wheel 56 .
As the most common hardware, screws and nuts are widely used in construction and machinery fields. However, existing screws and nuts are easily corroded to varying degrees in the natural environment, especially the threads on screws and nuts are corroded After that, the whole screw and nut are useless, and people have to discard them, which will inevitably lead to a lot of waste of resources.
The nut is based on the reaction force principle of the inner hexagonal cone of the clamping part and the outer hexagonal cone of the locking part. The higher the pressure, the tighter the lock, so that the bolt can achieve the purpose of self-locking and tightening. The existing bolts rely on multiple nuts against each other to prevent loosening. This method cannot be completely locked, and the bolts are easily loosened when subjected to huge pressure and vibration, which hides potential safety hazards;
