[0001] The invention relates to the field of electric spindles, in particular to a profile tracking electric spindle for a trimming machine. Background Art

[0002] The trimming machine is a professional mechanical equipment used to process the edge of the board. It is mainly used to remove excess material from the edge of the board to make the edge smooth and neat. The trimming machine is widely used in furniture manufacturing, decorative materials, woodworking and other industries. During the use of the trimming machine, the edge of the board is usually switched to different R angles according to design requirements. Different R angles refer to the different radii of the rounded corners formed on the edge of the board.

[0003] The tracking and profiling unit electric spindle and tracking wheel of the trimming machine currently on the market are separate, large in size and complex in structure. The separate design requires the electric spindle and tracking wheel to be installed independently, which makes adjustment difficult when switching to different R angles.

[0004] Regarding the above-mentioned related technologies, when different R angles need to be set according to design requirements, the relative positions of the electric spindle and the tracking wheel need to be accurately aligned. Any slight deviation will lead to processing errors. When the R angle changes, the alignment requirements are more stringent. Therefore, there is an urgent need for a trimming machine with an integrated electric spindle and a tracking wheel, which can realize rapid switching of the R angle by replacing the tracking wheel and the tool to improve work efficiency. Summary of the invention

This design enables the rotating component 4 to be driven efficiently and stably, and adapts to the high-precision processing requirements of the trimming machine. A wave washer is provided between the deep groove ball bearing 14 and the rear end cover 12. When the tool 2 runs at high speed, the deep groove ball bearing 14 will generate vibration and impact.
