Therefore, there is a need to design a bearing retaining ring disassembly and installation device that facilitates the installation and disassembly of the bearing retaining ring, and is safe and reliable.
Screw: A type of fastener consisting of a screw head and a screw rod (a cylinder with an external thread), which needs to be used in conjunction with a nut to fasten and connect two parts with through holes. and widely used in people's lives. In real life, due to the vibration of the machine, the workpiece is loose at the connection between the screw and the nut, and the nut needs to be tightened frequently, which is time-consuming and laborious, delays time, and reduces the production efficiency, so how to reduce the production process. Frequent tightening of screws has become an unsolved problem for people. Therefore, there is an urgent need to provide a slotted screw.
Guangdong Yueluo Hardware Industry Co., Ltd. is a screwing fixture, including a bottom plate, a bearing seat and a hydraulic press are respectively installed on both sides of the top of the bottom plate, a bearing is installed inside the bearing seat, and the inner ring of the bearing is connected to the support The bottom end of the vertical rod is snap-connected, the top end of the supporting vertical rod is fixedly connected to the supporting horizontal rod through an adjusting screw, the bottom end of the supporting horizontal rod is provided with a chute, and the inside of the chute is connected by sliding The slider is fixedly connected with the electric batch, the hydraulic press is connected with the fixed seat through the hydraulic rod, the top of the fixed seat is fixedly connected with the screw positioning plate through two fixed blocks, and the opposite side of the two fixed blocks is provided with Clamping mechanism for clamping workpieces.
Pre-embedded channels are often used in rail transit. There are usually U-shaped channels and C-shaped channels. There are also various widths of openings on one side. The T-bolts used in their connection are generally non-standard parts, which need to be The actual project needs to be customized, mostly for the overall stamping production, the mold cycle is long, the number of mold openings is large, and the production cost is high. Moreover, when assembling and connecting, it is sometimes found that the size of the originally designed t-bolts does not match, and it is necessary to replace t-bolts of different sizes, then it is necessary to redesign and produce non-standard t-bolts, which slows down the entire equipment. processing cycle. Customized T-bolts are often not wide enough in size range, and only a few can be selected for specific assembly and connection, which is difficult to meet the diverse requirements of the production site for bolts.
