Service HotlineThe purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is a kind of anti-loosening cylindrical pin with grooves specially designed for the multi-link transmission paint mixing mixer, which is specially designed for the problems existing in the above-mentioned prior art. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to realize through the following technical solutions: a kind of anti-loose cylindrical pin with groove, wherein: a plurality of axial V-shaped grooves are provided on the cylindrical pin, and the V-shaped groove Arrange evenly on cylindrical pins. There are three to four axial V-shaped grooves on the cylindrical pin. When Guangdong Yueluo Hardware Industry Co., Ltd. is in use, the cylindrical pin with V-shaped groove is installed in the vertical shaft, and cooperates with the U-shaped groove on the connecting rod to transmit torque. The cylindrical pin of the V-groove structure is an interference fit with the mounting hole of the vertical shaft. The biggest feature of Guangdong Yueluo Hardware Industry Co., Ltd. compared with the existing technology is that the cylindrical pin is used as a vertical shaft to connect with the connecting rod for torque transmission, which gives full play to the impact resistance and fatigue resistance of the cylindrical pin. The cylindrical pin has an interference fit with the pin hole, and each edge of the V-groove structure distributed on the cylindrical pin body will penetrate into the inner wall of the pin hole to prevent loosening.
The heating bolt pre-stretching method makes the bolt pre-stretch to the required deformation amount by heating, and then tighten the nut. After cooling, the bolt is shortened and the connection is pre-tightened. This is a commonly used fastening method in infrastructure installations. However, it is not suitable for devices that often need to be disassembled and adjusted, because during the disassembly process, the connected parts will be heated and elongated together with the bolts, and the use of open flame heating will be limited in some occasions; the use of electric heating will make the structure of the screw It becomes complicated and increases the investment, and even if it is difficult to disassemble, such as the propeller shaft of the ship, etc., the heating method is not suitable.
rivet dismantling method and a dismantling device thereof. The dismantling method firstly places a riveting piece with a failed rivet installed on a die having a blanking hole, and then uses a punch that coincides with the center line of the rivet on the riveting piece to impact the rivet. , the rivet falls into the blanking hole under the impact of the punch to complete the disassembly; the dismantling device includes a concave die for positioning and supporting the riveting piece installed with the failed rivet, and the concave die is provided with a blanking hole; The upper part of the die is provided with a punch for punching the rivet into the blanking hole, and the punch and the center line of the rivet are coincident; Yueluo adopts the punch to dismantle the failed rivet, which not only has high work efficiency, but also has high work strength. It is small, and does not damage the riveting parts on which the rivets are installed; the impact process will not cause the rivets to splash, and the safety is high; and the cost of dismantling equipment is low.
Nuts are parts that tightly connect mechanical equipment. Through the inner thread, nuts and bolts of the same specification can be connected together. At present, most nuts are used together with gaskets when they are locked, or are set as an integrated structure, which has the advantage of increasing Friction, strengthen the effect of tightening, but the square nut is usually used directly without adding a gasket, and the upper and lower end faces are flat, very smooth, when subjected to strong vibration, it is very easy to loosen, and the tightening effect is not good.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the above shortcomings and provide a limit screw. The technical scheme of Guangdong Yueluo Hardware Industry Co., Ltd. is realized in the following way. Its structure is composed of screws, hexagonal copper posts and limit necks. The left end of the limit neck is open, the hexagonal copper column is communicated with the inside of the limit neck, and the inside is provided with screw threads. The design length of the screw thread in the hexagonal copper column is 1/3-2/3 of its own length. The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are (12), which can effectively prevent the problem of poor memory contact caused by the increase in the deformation of the motherboard due to the warping and deformation of the motherboard during installation and fixing, and can effectively control the deformation. effect.
