What is the tolerance range of precision screws?
The head of the traditional screw is located outside the threaded hole and occupies a large space, which is not suitable for occasions with small space, nor is it suitable for occasions where the outer surface of the component is a working surface. For example, in the field of electronic products, or when connecting the shaft and the shaft sleeve, the machine screw with a fully threaded structure on the outer surface is widely used.
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 54 is opposite.
The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are that the rivet nut is fixed on thin-walled or thin-plate objects without welding, easy operation, high production efficiency, easy to manufacture, low cost, single-sided riveting, firm connection, no pollution, no noise, Has significant economic benefits.
Generally, the most commonly used material on the market is iron. The iron one is known as carbon steel. It is punched out or turned. After being manufactured, it is in its natural color. In order to prevent rusting, it is necessary to Electroplated. The stainless steel rivet nuts do not need electroplating. In the case of iron, the color of electroplating is generally determined by the customer, and the color of the electroplating depends on what color the customer needs. There are also some requirements for salt spray time. Some electroplating colors have a higher salt spray time, and some electroplating, less rust in a few hours. Another point is to see whether the customer needs to export the product. Generally, the export needs to be environmentally friendly, and some domestic ones also need it, but most of them are not needed.
