In this embodiment, the first driving mechanism, the second driving mechanism, and the third driving mechanism are all motors. In other embodiments, the motor may be replaced with other drive mechanisms that are known in the art or that may be implemented in the future.
In this embodiment, it is preferable that the second rotating shaft 5 is an output shaft of a motor 8, each motor 8 having the second rotating shaft 5 is directly fixed to the polishing disk mounting rack 4, and each polishing disk 6 is directly connected to the corresponding output shaft, so that the polishing machine is simple in structure, convenient to mount and use, and capable of meeting the requirement of high-speed polishing.
Further preferably, each of the motors 8 having the second rotating shaft 5 is a frequency modulation motor, so as to adjust the rotating speed of each of the motors according to actual requirements.
Furthermore, each motor 8 with the second rotating shaft 5 is a direct current motor and is respectively supplied with power through a storage battery; therefore, additional external power supply is not needed for power supply, and wiring is more convenient. In other embodiments, each of the motors having the second rotating shaft 5 is an ac motor, and then power is supplied through a brush provided on the first rotating shaft 3, which is not limited to the embodiment.
Referring to fig. 1 again, a buffer spring 7 is arranged on the support 1, and after the high-speed polishing head is connected with the polishing equipment through the support 1, the buffer spring 7 gives the support 1 a buffer force acting on the polishing equipment. Thus, in the actual polishing process, the bracket 1 has a movement margin relative to the polishing equipment, so that the pressure between the polishing disc and the wood board to be polished can be properly changed, and the polishing requirements of the wood boards to be polished with different thicknesses can be matched.
In this embodiment, the sliding installation structure of the rotating shaft installation block 2 and the bracket 1 is as follows: two parallel slide rails 1-1 are arranged on the bracket 1, and a slide block 2-1 matched with each parallel slide rail 1-1 is arranged on the rotating shaft mounting block 2; the first rotating shaft 3 is positioned in the middle of the interval between the two parallel sliding rails 1-1. Thus, the running stability of the spindle mounting block 2 on the carrier 1 can be ensured to the greatest extent during the actual polishing process.
Further preferably, the sliding rail 1-1 and the sliding block 2-1 are assembled together through a T-shaped structure matched with each other. Therefore, when the pressure or thrust changes, the rotating shaft mounting block 2 can still normally and stably run on the bracket 1.
In other embodiments, the positions of the slide rail and the slide block may be changed according to actual needs, for example, the slide rail is disposed on the rotating shaft mounting block 2, and the slide block is disposed on the bracket 1, so that similar technical effects can be achieved.
