With the rapid development of China's machinery industry, especially the development of heavy industry, the demand for large-scale metal processing equipment is increasing; at the same time, higher requirements are also placed on the technical parameters of the equipment. For some large-scale CNC equipment, to ensure the machining accuracy of the whole product, it is not only necessary to rely on high-performance components such as full closed-loop control and precision transmission components, but also requires the positioning and stability of the joint surfaces between the large and medium-sized components of the equipment. The common positioning of the joint surface between large components adopts flat key positioning, and this method requires processing the keyway at the joint surface of the large components. Since the joint surface of large parts is affected by factors such as processing and splicing, it cannot guarantee that the keyways on the large parts combined can be matched according to the theoretical requirements. Therefore, the positioning flat key needs to press the flat key in the two parts of large parts. Different repair allowances Trim into a stepped shape. The height difference of this keyway in different large components makes a single flat key need to be repaired on four sides, which increases the difficulty of the key repair process and makes it difficult to improve work efficiency. Not only that, when the flat key is repaired and assembled, it must be in an interference fit with the keyway, which makes the disassembly and assembly of the flat key more laborious.

Yueluo is about a special fastener and its screwdriver. That is, the Y screw and its screwdriver. In order to prevent the leakage of new product manufacturing technology and prohibit others from arbitrarily opening the shell of the new product or disassembling the relevant parts, it is necessary to take effective precautions against their own products, and the use of special fasteners is one of the purposes of Yueluo. This kind of screw can also be widely used in the fixation of some public equipment, for the fastening and fixing of parts that are afraid of disassembly and theft, so as to play a certain protective role.

At present, in the standard cabinets of computers, networks, automation, etc., to fix the equipment in the cabinet, it needs to be fixed by using fasteners. The nuts in the existing fasteners are ordinary nuts, which are internal card structures. , there are the following shortcomings: 1. The installation and disassembly are complicated, and a large amount of force is required to insert the nut during installation and disassembly, and the nut cannot be installed and disassembled at all due to the processing error of each nut; 2. After the nut is used for a long time, the nut The card edge will have slack problem, which will affect the use; 3. Installation or disassembly is easy to cause problems such as falling, which may cause electrical short circuit, etc., and there are potential safety hazards; 4. The efficiency of equipment installation is low.

The paint mixing mixer used for color matching in the auto repair industry uses a multi-link connection transmission as the main driving force. The transmission of torque has higher quality requirements for the impact resistance and fatigue resistance of the cotter pin. During the use of the cotter pin, it was found that the cracking phenomenon occurred due to insufficient strength, resulting in the machine not running. In the existing multi-link transmission mode of the paint mixing mixer, the connecting rod drives more than 10 paint pots in each layer of the frame to stir, and the bottom connecting rod is also responsible for the transmission of the torque of the upper connecting rod, which leads to the connection between the connecting rod and the connecting rod. The pins connected by the rods must have strong impact resistance and fatigue resistance, and must have a certain anti-loosening function.

At present, there are two commonly used nut fixing methods, one is welding fixing: high energy consumption, the welding process easily leads to thread deformation in the nut, which requires re-tapping, which increases the cost, and for aluminum alloy and other materials, the welding process is poor, It is easy to produce welding defects and cannot achieve the function of fastened connection; the other is to pull riveting: in this method, the connection force of the nut is not strong, the reliability is not good, and it is not suitable for thin-walled profiles.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: four-claw furniture galvanized nuts, tapered washers, DIN933 bolts, 12.9-level sets of screw accessories and other products, we can provide you with suitable products Your fastener solution.
