Service HotlineThe paint mixing mixer used for color matching in the auto repair industry uses a multi-link connection transmission as the main driving force. The transmission of torque has higher quality requirements for the impact resistance and fatigue resistance of the cotter pin. During the use of the cotter pin, it was found that the cracking phenomenon occurred due to insufficient strength, resulting in the machine not running. In the existing multi-link transmission mode of the paint mixing mixer, the connecting rod drives more than 10 paint pots in each layer of the frame to stir, and the bottom connecting rod is also responsible for the transmission of the torque of the upper connecting rod, which leads to the connection between the connecting rod and the connecting rod. The pins connected by the rods must have strong impact resistance and fatigue resistance, and must have a certain anti-loosening function.
Today's advanced manufacturing represented by large aircraft, large power generation equipment, automobiles, high-speed trains, large ships, and large complete sets of equipment has entered an important development direction. As a result, fasteners will enter an important stage of development. High-strength bolts are used for the connection of important machinery, and repeated disassembly or various installation torque methods require extremely high-strength bolts. Therefore, the quality of its surface condition and thread accuracy will directly affect the service life and safety of the host. In order to improve the friction coefficient and avoid corrosion, seizure or sticking during use, the technical requirements stipulate that the surface should be treated with nickel phosphorus plating. The thickness of the coating is guaranteed to be within the range of 0.02 to 0.03 mm, and the coating is uniform, dense, and free of pinholes.
The t-bolt can be directly put into the groove of the aluminum profile. It can be automatically positioned and locked during the installation process. It is often used in conjunction with the flange nut. profiles to choose from. T-bolts are movable anchor bolts. The existing t-bolt is easy to rotate and swing in the slot during use, which brings some inconvenience to the use of the t-bolt.
At present, drum brakes are usually used for rear brakes of automobiles, and pump parts assemblies are widely used. The traditional assembly method is to use tools such as screwdrivers and retaining ring pliers for assembly. The disadvantage is that the assembly efficiency is low, the accuracy is average, and assembly quality problems are prone to occur, which affects the performance of the product assembly. Now take the brake wheel cylinder assembly with automatic clearance adjustment mechanism produced by our factory as an example to illustrate the installation of the elastic retaining ring
screw suitable for a variety of tools is a single-structure threaded part, including a screw body and a screw head. The outer surface of the screw body is processed with an external thread 1, and the outer side of the screw head is formed by six screw heads. Prismatic, the top surface of each edge of the outer hexagonal prism is a boss, between each boss is an end face groove 4, and the middle of each boss is provided with an end face hole 3; the inner side of the screw head is formed by six screw heads. The side surface 5 forms an inner hexagonal prism hole, and the bottom of the inner hexagonal prism hole is processed with a cross groove 12 .
