Screw (pinyin: luógǎn, English: screw): a cylinder with a spiral groove cut on the outer surface or a cone cut with a tapered spiral groove. The screw has a different head, the head is called an external hexagon screw. There are others, such as large flat screws, socket head screws and so on.
Usually, a tight fit is used between the cylindrical pin and the pin hole, such as the cooperation between the cylindrical pin and the pin hole on the rotating shaft of the motor. Due to the tight fitting structure between the cylindrical pin and the pin hole, the shaft with the pin hole needs to be well positioned during assembly, and then the cylindrical pin is aligned with the pin hole, and then knocked or pressed to fit. The cylindrical pin is pressed into the pin hole. There is no device specially used for the installation of cylindrical pins in the prior art, and two or more people are required to cooperate to install the cylindrical pins into the pin holes. installation quality.
In 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.
Rivet riveting has the advantages of simple process equipment, shock resistance, impact resistance, uniform force transmission, firmness and reliability, etc. The key parts of mining equipment such as skips, cages, dumpers, and mine trucks are all connected by rivet riveting. The quality of rivet riveting directly affects the product quality, working performance and service life of mining equipment. The number of rivets used in mining equipment is huge. Each mining equipment requires one hundred or hundreds of rivets, and they are used in mining equipment. The specifications of the rivets in the equipment are large, and the riveting process of hot riveting is mostly used. The riveting tools required are riveting machines and rivet molds.
