Service HotlineScrew (English a screw) refers to the parts used in construction machinery. It is a kind of threaded parts with sharp ends such as nails, small cylindrical or conical metal rods, with grooved or dimpled heads, and used alone. . The detection of the screw should start from the wire of the screw. The quality of the precision screw is directly related to the wire that produces the screw. A good screw wire will open the screws more beautifully. What screw head burst, what thread is bad. Good screw wires generally do not find this situation.
The inner hole retaining ring groove processing mechanism is characterized in that: it comprises a pneumatic grinder fixed block installed on the tool table of the lathe, a pneumatic grinder installed on the pneumatic grinder fixed block and a grinding wheel piece installed on the front end of the pneumatic grinder; The pneumatic grinder mounting block is provided with a pneumatic grinder installation through hole, and there are at least 2 screw holes above the pneumatic grinder installation through hole; the grinding wheel is designed according to the diameter of the product and the thickness of the groove width, in order to increase the strength of the grinding wheel , Add flanges at both ends of the grinding wheel to improve the strength of the grinding wheel. The grinding wheel piece includes the connecting blade on the flange plate. The center of the flange plate is provided with a mounting hole installed on the pen-type pneumatic grinder. The diameter of the mounting hole is 17.8- 18mm, the diameter of the grinding wheel is 18-20mm.
In the prior art, the spring washer has a certain anti-loosening effect. However, due to the unreasonable design structure, the upper and lower pressing forces of the spring washer and the spring washer's anti-return force are poorly matched, resulting in the smooth surface and the bolt head. The friction between the nut and the connected parts is small. When the bolt or nut is subjected to strong vibration, the bolt or nut will still loosen. Therefore, the anti-loosening effect of the above spring washer still needs to be improved.
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.
In order to solve the above technical problems, Yueluo provides a screw installation method. When using this method to install screws, the sensor must sense that the screws have been adjusted to the specified position before allowing the screws to be energized, which prevents the screws from being adjusted. Accidents of personal injury caused by operating errors during the process. The technical solution adopted by Yueluo to solve its technical problems is a screw installation method, which includes the following steps: a. Fix the screw hole structure that needs to be installed on the workbench, and fix the corresponding size screw to the screw mouth; b. Adjust the sensor on the track groove to the vertical position just above the screw hole structure; c. Adjust the screw position until the sensor on the screw senses the signal sent by the sensor; d. Turn on the screw power supply, and install the screw into the screw Inside the hole structure, the installation is complete. Compared with the prior art, Yueluo has the following beneficial effects. The screw installation method provided by Yueluo has the steps of preventing accidental hitting, which avoids personal injury accidents caused by operation errors during the screw adjustment process.
