Service HotlineAn elastic cylindrical pin loading and unloading tool, comprising a rectangular base on which a hollow cylindrical tooling station is arranged for fixing a tooling and installing a cylindrical pin on the tooling for shear force testing, the The tooling includes an outer cylinder and an inner cylinder that are assembled together, the outer cylinder and the inner cylinder are in clearance fit, and the base is further provided with a counterbore for taking out the inner cylinder after the tooling test is completed.
Contents of the utility model Guangdong Yueluo Hardware Industry Co., Ltd. is to solve the problem of needing one hand to hold the screw when screwing the screw at present, and to provide a screw fixture that can screw the screw without holding the screw by hand. Guangdong Yueluo Hardware Industry Co., Ltd. adopts the following technical solutions. Guangdong Yueluo Hardware Industry Co., Ltd. includes a clamp sleeve, and the middle of the clamp sleeve is a through hole. The outer end of the pivot pin is in contact with the spring. The beneficial effect of Guangdong Yueluo Hardware Industry Co., Ltd. is because Guangdong Yueluo Hardware Industry Co., Ltd. is provided with a rotating pin on the shaft of the fixture sleeve that can contact the screw, and the outer end of the rotating pin is in contact with the spring, so that the screw It is easy to fix in the through hole of the fixture cover, and the screwdriver is also in the through hole of the fixture cover, which ensures the alignment of the screw and the screwdriver, so it is avoided to hold the screw by hand, and the screw is quickly screwed to the object. in vivo.
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.
In order to solve the problem of poor waterproof performance of the existing rivets, Guangdong Yueluo Hardware Industry Co., Ltd. provides a waterproof rivet. By arranging a figure-eight waterproof part for waterproofing on the lower end surface of the waterproof cap, when the object is riveted, The waterproof cap is subjected to the pulling force of the rivet rod and the supporting force of the object. The pulling force and the supporting force cause the waterproof cap to generate stress, which in turn causes the waterproof part of the waterproof cap to be micro-deformed in the closest contact with the object, so as to achieve a good sealing effect.
Earless retaining ring (known as Constant Section Rings abroad) is also called constant section retaining ring, because the cross section is equal, and there is no ear part protruding from the traditional stamping retaining ring, so it is called earless retaining ring. Earless retaining ring and spiral retaining ring have similarities in production, processing and use characteristics. They are both flattened and wound by steel wire. After heat treatment and surface treatment, they have good elasticity and toughness. Earless retaining ring is divided into two types: shaft use and hole use, and there are various forms of tail ends to choose from. The application of earless retaining ring is the same as that of traditional C-type retaining ring, which is widely used in hydraulic parts assembly, valves, instruments, various lock core components, needle roller bearings, pulleys, connectors, quick connectors and other mechanical assemblies.
