Service HotlineAt 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
With the advancement of technology in various industries, the current structural design of screws has evolved from just simple locking to focusing on work efficiency during the locking process and not destroying the integrity of the objects to be locked. The new cases such as No. 556784 screw improvement and No. 289414 screw that integrates locking, stability, labor-saving, fast and multi-function, which were previously designed and approved and published in the Central Taiwan Bulletin, are the main representatives of screws. It is clear that It is learned that the two cases not only fully improve the shortcomings of the traditional simple locking screws, but also achieve the purpose of substantial improvement of the screws designed in each case in actual use.
At present, the stopping method of the pin shaft stop pin of the general hydraulic excavator is mainly by using a long bolt to pass through the pin shaft stop sleeve pin hole and the pin shaft pin hole, and then use a double nut on the other end of the bolt to force it away from the pin shaft. The outer circle of the stop sleeve is about 2 3mm away to prevent the bolts and nuts from falling off. Due to the structure in which the double nuts are pressed against each other, the disassembly and assembly efficiency of this pin shaft stop method is not high, and two wrenches are required for each assembly and disassembly, which is extremely troublesome.
double-headed pin puller includes a slider hammer and a sliding rod, two ends of the sliding rod are respectively provided with different types of pin-pulling parts, the pin-pulling parts are threadedly connected with the sliding rod, and the sliding rod is also provided with There is a sliding rod limit block, and the sliding rod is slidably connected with the slider hammer. The double-headed pin puller can install two types of pin-pulling heads at the same time, and can pull out two different types of pins. It is easy to use and has high work efficiency. Disadvantage: Single function, cannot be used to install pins.
rivet is a nail-shaped object used to join two parts or components with a through hole and a cap on one end. In riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are not limited to the form. The existing switch is not easy to fix, and needs to be supported by others during installation, which leads to waste of labor, and at the same time, it is easy to damage the hands of the supporting personnel. The existing device driving method is relatively laborious. Some devices require rivets of different lengths in different thicknesses, and cannot be assembled by themselves of the same type.
