Service HotlineAn asphalt pavement screw, the asphalt pavement screw includes a main rod, an outer jacket, a pressing piece and a nut, the main rod is a columnar rod, the lower end of the main rod is provided with a table for supporting the outer jacket, and the middle part of the main rod passes through the outer jacket The upper part of the main rod is provided with a threaded section, the pressing piece and the nut are set on the threaded section, and at least two deformation holes are provided on the outer sleeve, and the middle part of the deformation hole is larger than the upper and lower sides of the deformation hole, The part between the adjacent deformation holes is the deformation part, and the width of the middle part of the deformation part is smaller than the width of the upper and lower sides of the deformation part. After the asphalt pavement screw of Guangdong Yueluo Hardware Industry Co., Ltd. is assembled, it has strong bonding force with the asphalt road. Even if it is hit, it will not be separated from the asphalt road. Using this asphalt pavement screw to fix the road railing can strengthen the road railing. The firmness of the assembly.
According to the process, the PortlandPortlandwing nut can be divided into cold heading PortlandPortlandwing nut, casting PortlandPortlandwing nut and stamping PortlandPortlandwing nut. According to the shape, it can be divided into two basic shapes: square wing and round wing. According to the national standard number, it can be divided into GB/T62.2-2004 Square Wing Wing Nut Wing Nut Round Wing Wing Nut Round Wing GB/T62.1-2004 Round Wing Wing Nut
Most of the blind hole installation rivets have the characteristics of light weight, reliable connection, high strength, and convenient and quick installation. For example, Portlandblind rivets have been widely used in various aerospace vehicles.
An automatic screw-removing device for automatically removing screws on a workpiece, the automatic screw-removing device comprising a worktable, a manipulator disposed on one side of the worktable, and a screw-removing mechanism installed on the manipulator, The screw-removing mechanism includes an installation plate connected to the manipulator, an electric batch installed on the installation plate, a bit head disposed on one side of the electric batch, and a visual recognition unit disposed on the installation plate , the visual recognition unit takes pictures of the screw to determine the coordinates of the screw, the bit is rotated under the drive of the electric batch to disassemble the screw, the bit is magnetic and can be adsorbed the screw.
As we all know, whether it is the necessities in people's life or the equipment in industrial production, there will be a structure of screws and screw holes on it. This kind of structure that can simply fix some components together has been widely used in various fields. For the installation and removal of screws, people invented manual screwdrivers, and then to electric screwdrivers and so on. For manual screwdrivers, the operator needs to manually install or remove the screws. When encountering small screws, it can still handle it. When encountering large screws, due to people's limited strength, they may not install the screws in place, so it was invented. Electric screw. When installing the screw, which is widely used in the market, the operator needs to hold the screw handle, fix the screw on the screw port, and then align the screw with the corresponding screw hole for screwing. The disadvantage of this kind of screw is that it is heavy in quality and laborious to operate, and secondly, the operator will be injured due to operating errors, and the consequences are extremely serious. In view of this deficiency, people fix the screws on a work frame, so that before installing the screws, the operator only needs to adjust the screws to the designated position, and then the screws can be installed, which is convenient and simple. However, there are still potential safety hazards. In the process of adjusting the screw, it is still possible that the power of the screw may be turned on by mistake due to operating errors, resulting in injury to the operator. In view of the above-mentioned defects, it is necessary to invent a screw installation method with an anti-missing function.
