What is the tolerance range of precision screws?
At present, more rivets are used on car tires. Due to the long-term bumps of the car, traditional equipment is prone to loosening during the use process, which affects safety. The above problems need to be improved on traditional equipment, so how to design a Rivets on car tires, this becomes a problem we need to solve.
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.
The purpose of Yueluo is to provide a screw with a plurality of threads continuously coiled in a helical shape formed on its shank; wherein the shank is provided with a protruding cutting portion at the front section with threads toward the tip, for the purpose of providing the screw. The front section is screwed into the object to successfully complete the stage of cutting and rapid chip removal, and the rod part is provided with a concave cutting part at the rear section with threads toward the head, for the rear section of the rod to be introduced into the object. , so that the work of the stage of cutting and collecting chips can be successfully completed; so that the screw can achieve multiple functions such as labor-saving cutting, smooth and rapid chip removal and chip collection during the locking process.
Sprinkle the excess flat washer 6 on the positioning plate II3-1 on the flat washer positioning plate 3, and shake the flat washer positioning plate 3 by hand. After a short time, the flat washer 6 will be positioned and arranged on the upper positioning plate II3-1. In the flat washer hole 3-7, since the width of the opening groove 113-32 of the baffle plate II3-3 is smaller than the diameter of the flat washer hole 3-7, and the thickness of the upper positioning plate II3-1 is designed according to the thickness of the flat washer 6, each Only one flat washer 6 can be accommodated in the flat washer holes 3-7 of each upper positioning plate II3-1, and then use a brush to remove the excess flat washer
