Service HotlineIn another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35, and the screws enter the screw accommodating hole 46 from the discharge port through the guide rail 6. The slotting is carried out, which improves the efficiency and saves the labor cost.
The isolating switch in the substation has a large workload for maintenance. The transmission parts such as the isolating switch connecting rod are mostly connected by cylindrical pins. The shaft-pin fit is generally 1mm, which is tight. If the cylindrical pin is disassembled during the maintenance process, it is often due to corrosion and mechanical deformation. It is difficult to proceed smoothly for other reasons, and if the working environment is a small space, it is more difficult to disassemble. In traditional operations, grinding, hard prying, or beating with a hand hammer are often used to disassemble, which will further deform the pins, and when the space is small, it is difficult to use tools such as hand hammers. solve.
Wire cutters are widely used tools in electromechanical and other industries, and rivets are widely used standard parts, especially in the manufacturing or maintenance process of the electromechanical industry. Because the currently used wire cutters are mostly used to cut finer steel wires or various wires and twist small screws and nuts. In the process of work, rivets of various specifications are often encountered temporarily. For example, suitable rivets cannot be found at the scene, or other replacements will cause inconvenience to the work, which not only affects the output, but also affects the quality.
In recent years, a spring pin connection structure has appeared in the connection between the beam and the column: a pin hole is arranged on the column, and a spring pin is arranged at the end of the beam. When installing, the spring pin can be inserted into the pin hole. However, when more than two spring pins are used, if the spring pins are slightly deviated from the pin holes, it is difficult to spring into the pin holes; and if the pin holes are drilled larger, although the spring pins are easy to spring in, it will cause the spring pins to spring into the pin holes. Looseness with pin hole. In addition, after the spring pin is used for a long time, the spring is easily corroded and fractured, which also leads to structural instability and difficulty in disassembling the beam.
Iron two combination screws can be sucked up with magnets, but stainless steel two combination screws are difficult to be sucked up. Environmentally friendly three-combination screws and non-environmentally friendly ones are invisible to the naked eye and require mechanical testing. It cannot be judged with the naked eye and out of thin air. The specifications of the two combination screws need to be determined by the national standard. The salt spray of the two combination screws needs to be measured with a salt spray machine for how many hours.
