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.
The main part of the pin screw is an ordinary screw, and the pin can be arranged in the melting section of the screw or the drop groove of the metering section or the smooth cylindrical surface without screw grooves at the end of the metering section. The pins are arranged in a certain arrangement, with varying degrees of density and quantity. Cylindrical pins are formed by fitting the pins into the holes of the threaded rod; square or diamond-shaped pins are formed by milling directly on the threaded rod. If these pins are set in the melting zone, the pins can break up the solid bed, destroy the two-phase flow, stir the solid and liquid phases together, increase the contact area between the undissolved solid phase fragments and the contained material, and promote molten. If the pin is set in the melt conveying area, its main function is to divide the material flow, increase the interface, change the direction of the material flow, and rearrange the flow beam. Divide and merge multiple times, change the flow direction, and homogenize the melt composition and temperature. The mixing section is an inwardly slotted structure arranged at the end of the common screw homogenizing section, and its outer diameter is equal to the outer diameter of the screw. The grooves are divided into several groups, and each group is the confluence area of the material. The materials are divided by grooves, meet in the confluence area, and then divide and confluence. The principle is similar to the pin type. The characteristic of the separate screw is that in addition to the original screw thread (called the main screw) on the melting section, there is also an additional thread (called an additional thread) whose outer diameter is slightly smaller than the outer diameter of the main thread, and the main and auxiliary threads are With different leads, the secondary thread starts from the end of the feeding section (and connects with the feeding section here), and after several threads, gradually intersects the main thread of the homogenizing section. The screw groove depth and thread lead of this kind of screw change gradually from the beginning of the feeding section to the end of the homogenization, that is, the thread lead gradually narrows from the width, and the groove depth gradually becomes shallower from the depth, which can maximize the compression of the material.
In industrial production, some products need to remove the fixing screws; or in the assembly line, the screws that fix the product on the fixture also need to be removed when the product is unloaded. At present, the dismantling of the screws is mainly completed by the manual operation of the operator. However, this method of manually dismantling the screws has low work efficiency and high production cost.
Guangdong Yueluo Hardware Industry Co., Ltd. discloses an eccentric special-shaped rivet, which has a simple structure and is inexpensive to manufacture. The eccentric shaped rivet includes a cylindrical head and an eccentric polished rod. The diameter of the cylindrical head is larger than that of the eccentric polished rod. The eccentric polished rod is arranged at the lower end of the cylindrical head, and the axis of the eccentric polished rod is not the same as the axis of the cylindrical head. on the same straight line. The eccentric special-shaped rivet has low manufacturing cost and is easy to realize automatic assembly.
During the tightening process of the screw, do not use excessive force, otherwise the product will be damaged. The traditional bolt locking adopts manual operation, which is inefficient and insufficient force. In the existing screw locking device, before locking the screw, the locking force of the screw is tested, but the test equipment is set separately, resulting in a complicated structure. In addition, in the existing screw locking device, when the screw is locked, the position of the screw hole is not corrected, so that the screw often causes damage to the product during the tightening process.
