The use of non-mechanical means of driving linkage can simplify the mechanism, shorten the transmission chain, and facilitate the realization of automatic control. However, for a composite table that requires high transmission accuracy and a shaped motion transmission chain, such as the generative movement of the gear and the indexing motion transmission chain, hydraulic, electrical, and pneumatic methods are not yet used to realize the internal contact transmission of the motion. For the drive chains of simple surface forming motions that do not require high transmission precision, such as the lathes, milling machines, etc., the cutting speed and the drive of the feed drive, it is more commonly used hydraulic, electrical and pneumatic methods to achieve the transmission linkage. .
Machine tool transmission system: The specified graphical symbols represent the various transmission components in the mechanical transmission system of the real machine tool, and the integrated schematic drawing of the machine tool transmission chain is called the machine tool mechanical transmission system diagram, which is referred to as the machine tool transmission system. This diagram concisely represents the internal structure of the machine tool and the various transmission chains, and is a powerful tool for analyzing the transmission law of the machine tool. Familiar with the transmission system diagram, it is very important for the dump and research machine tools. With the transmission system diagram, the performance, working principle and application range of the machine tool can be analyzed, and various adjustment calculations can be performed.
The connection between mechanical and non-mechanical transmissions of machine tools
The drive connection on the machine tool, whether it is the internal contact drive or the external contact drive, can be realized not only with the mechanical transmission of the rigid body drive, but also with the non-mechanical drive mode according to the nature of the movement, such as hydraulic, electrical, Pneumatic, light and heat. With the rapid development of microelectronics technology, the current way of controlling movements and achieving transmission linkages by computers or electronic hardware is getting more and more applications.
