It is understood that, because the machine table 10 has a large volume, it is generally impossible to finish the machine table to improve the precision thereof, and therefore, in practical production, the precision of the table top of the machine table 10 is generally not high in order to reduce the cost.

The base plate assembly 20 includes a base plate 21 disposed on the machine table 10, a plurality of spacers 22 disposed on the base plate 21, a barrier 23 disposed on the base plate 21, and a L-shaped connecting member 24 disposed between the base plate 21 and the machine table 10. the base plate 21 may be fixed to the machine table 10 by means of fasteners such as bolts, etc. by improving the accuracy of the base plate 21, it is possible to isolate the defect that the accuracy of the machine table 10 is not sufficient, specifically, in the present embodiment, the base plate 21 has a flatness of less than 0.05 and a parallelism of less than 0.02. since the base plate 21 may be processed independently, by disposing the base plate 21, it is not only convenient to process, but also possible to reduce the processing cost, and also to improve compatibility, the spacer 22 is disposed between the base plate 21 and the base 30, it is possible to reduce the contact surface between the base 30 and the base plate 21, the contact surface is reduced to reduce the transmission of errors of the base plate 21. it is understood that the flatness and parallelism of the spacer 22 should also meet the accuracy requirements when the barrier 23 is disposed on the base plate 21, it is used to ensure that the mounting of the spacer 21 is disposed on the winding mechanism of the base plate 21, especially, it may reduce the accuracy of the mounting of the spacer 24, thus, it may reduce the mounting accuracy of the spacer 35 when the mounting of the spacer 21, it may reduce the mounting mechanism 3621, it may reduce the mounting of the spacer 21, and may reduce the mounting mechanism, and may reduce the mounting of the spacer 21, and may reduce the mounting of the spacer 3, and may reduce the mounting mechanism.

The base 31 is fixedly disposed on the substrate assembly 20, and specifically, the base 31 is disposed on the spacer 22. The bobbin base already has a certain basis due to the precision design of the base plate assembly 20. At this time, it is necessary to ensure the precision of the base 31, that is, the precision of the surface of the base 31 where the substrate 21 or the spacer 22 contacts, such as flatness or parallelism. It is conceivable that the flatness and parallelism should be in accordance with the accuracy requirements of the entire machine. The base 31 also abuts the bars 23 to ensure parallelism between the base 31 and other bases. The first and

second mounting blocks

32, 33 are spaced apart and are used to mount the winding drive mechanism 40, which will be described in detail below in connection with the winding drive mechanism 40. The first and

second mounting platforms

second mounting bases

32 and 33 are integrally formed with the base 31 to ensure the machining accuracy and consistency in machining. The base 31 also includes a third mounting hole 311 for mounting the components of the winding drive mechanism 40. Since the substrate 31 itself is integrally formed, when the third mounting hole 311 is formed thereon, the machining accuracy, such as the degree of alignment, can be controlled completely.

second mounting holes

321 and 331 opposite to each other must be ensured and is less than 0.03, and in this embodiment, the parallelism of the two end surfaces of the first and

second mounting holes

second mounting holes
