Service HotlineAs an important connecting part in the automobile assembly process, the screw plays a vital role in the safety performance of the automobile. The assembly of each component of the vehicle cannot be separated from the function of the screw. In the connection of the automobile assembly and its parts, the screw connection As well as simple structure, easy maintenance and disassembly, it is widely used. There may be thousands of screws on a car. The screw connection of each part has its own function and function. Once one or some screw connections fail, it will be It will lead to the loosening or even separation of the connected parts. If the car is running, it is likely to cause some parts to fail or break away. The light ones will cause the main functions of the car such as steering and braking to fail, potentially affecting driving safety. If it is not found in time, it will lead to major safety accidents and even endanger the lives of people. The failure of the car screws will cause the safety hazard of the whole vehicle, and will also cause customers to worry and complain, thus affecting the reputation of the company and endangering the life of the company. cycle.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the slotting device 4 includes a motor 41 and a motor 43, the cutting wheel 42 is fixedly arranged at the output end of the motor 41, and the motor 41 drives the cutting wheel 42 to rotate to open the screw. slot, the motor 43 is fixedly arranged on the workbench 1, the motor 41 is arranged on the motor 43, a track 47 is arranged between the motor 41 and the motor 43, the motor 41 can reciprocate through the track 47, and when the screw is slotted, the motor 41 drives the cutting wheel 42 to move in the direction of the screw. When the slotting is finished, the motor 41 drives the cutting wheel 42 to retract. The fixed wheel 48 is arranged at the output end of the motor 43. The fixed wheel 48 is located directly below the cutting wheel 42. The surface of the middle screw is in contact, and the motor 43 drives the fixed wheel 48 to rotate to grind and polish the surface of the slotted screw to make the surface smooth. Preferably, the direction of rotation of the cutting wheel 42 and the fixed wheel 54 is opposite.
At present, it has become very common to use automated tools to hit screws. However, when the material of the fastening object is relatively soft, the screw fastening is often prone to skew, not sticking, and the screw hole is damaged during the fastening process. Metal shavings can also be created in the shards, which can short out the board.
4. Manufacturing and assembly Due to the limitations of manufacturing technology and accuracy, there are sharp corners on the edge of the thread or the dimensional coordination between parts is not coordinated. During the initial assembly, the screw-in and screw-out torque may fluctuate or fluctuate to a certain extent. After a certain number of running-in, more accurate reusability characteristics of the lock nut can be obtained.
T-bolt, the European standard is called hammer bolt, the material is carbon steel, the surface is galvanized or nickel-plated, the T-bolt can be directly put into the groove of the aluminum profile, and it can be automatically positioned and locked during the installation process. Used in conjunction with the blue nut, it is a standard matching connector when installing corner fittings. It can be selected and used according to the profile groove width and different series of profiles. When the T-bolts on the market are installed with the installation channel, the bolts need to be placed into the channel from the port of the channel, and then tightened when moving to the designated position. The bolts are easy to rotate during installation, and the connection is not tight. Therefore, it is necessary to propose a mounting structure that uses T-bolts and grooves.
