Service Hotlinedouble-headed pin puller includes a slider hammer and a sliding rod, two ends of the sliding rod are respectively provided with different types of pin-pulling parts, the pin-pulling parts are threadedly connected with the sliding rod, and the sliding rod is also provided with There is a sliding rod limit block, and the sliding rod is slidably connected with the slider hammer. The double-headed pin puller can install two types of pin-pulling heads at the same time, and can pull out two different types of pins. It is easy to use and has high work efficiency. Disadvantage: Single function, cannot be used to install pins.
In the fastening connection parts and parts assembly of various equipment and tooling, if the screw and nut anti-loosening treatment is required, there is a contradiction between anti-loosening and tightening or tightening and loosening. For example, the resistance is large when tightening. , or the resistance is large when loosening, or the anti-loosening effect is not good, or the service life is short, and it will be scrapped after 2 to 3 times of use. In a word, all kinds of anti-loosening nuts have the above problems at present. Therefore, it is necessary to utilise a new type of anti-loosening nut with low resistance when tightening or loosening, but with better anti-loosening effect and long service life.
The production of non-standard round flat pads can only be processed on ordinary lathes without punching machines. Processing with round steel is difficult, material waste is large, tool loss is large, and efficiency is low. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a non-standard circular flat pad lathe processing fixture, which is suitable for the production of various non-standard circular flat pads. Yueluo is realized in this way. It includes a hollow square support, a bolt and a circular machining groove. It is characterized in that a circular machining groove is left on one surface of the hollow square support. There are 4 bolts evenly connected. The advantages of Yueluo are: 1. Reduce the difficulty of processing; 2. Save materials (can use corner waste); 3. Reduce tool wear; 4. Improve production efficiency.
An automatic circlip device discloses an automatic circlip device capable of realizing automatic assembly of the circlip to improve production efficiency and reduce labor costs. However, there are problems of low degree of automation and low work efficiency.
In order to solve the problem of nut loosening, various self-locking nuts have appeared, which have complex structure, high production cost, inconvenient installation and unsatisfactory anti-loosening effect. At present, the never-loosening nuts produced in Japan are mostly used, mainly in the form of double nuts. Each nut is provided with an eccentric cam protrusion, and each nut is provided with a groove and an inclined plane to squeeze the cam protrusion of each nut. When pressing, the cam protrusion of the nut will move to a small radius along the slope of the nut, so that the nut will not loosen, but whether it is a nut or a nut, it is always under the action of eccentric force. In addition, various non-loose nuts designed by many manufacturers are to increase the friction between the nut and the fastening workpiece or increase the barb to achieve the purpose of never loosening, but the effect is not ideal.
