[0024] The utility model is further described below in conjunction with embodiments.

[0025] Embodiment 1:

[0026] See also Figure 1-Figure 5 The cleaning assembly 5 includes an electric push rod B51 arranged on one side of the L-shaped plate 3, a moving box 52 arranged at the telescopic end of the electric push rod B51, and a cleaning box 53 arranged on one side of the workbench 1. A motor 54 is arranged on the inner wall of the moving box 52. A rotating shaft 55 is fixedly installed on the output end of the motor 54. The upper end of the rotating shaft 55 is fixedly connected to the bottom of the knife storage disc 4. A cutter head groove 56 is opened on the upper surface of the knife storage disc 4. There are six groups of cutter head grooves 56. A screen 57 is arranged inside each group of cutter head grooves 56. A sponge block 58 is arranged on the inner wall of each group of cutter head grooves 56. An air pump 59 is arranged above the cleaning box 53. A connecting pipe 591 is arranged at one end of the air pump 59. Two groups of connecting pipes 591 are arranged. One group of connecting pipes 591 is connected to the outside world, and the other group of connecting pipes 591 is connected to the outside world. 1 is provided with an annular air pipe 592 at one end, and an air jet 593 is provided on the outer surface of the annular air pipe 592. A cutter head 6 is provided on one side of the sponge block 58. First, the motor 54 drives the rotating shaft 55 and the cutter storage disc 4 to rotate, so as to facilitate the replacement of the required cutter head 6 by the cutter changing assembly. After the used cutter head 6 is put back into the cutter head slot 56, the L-shaped plate 3 is located at the position of the cleaning box 53 through the extension and contraction of the electric push rod A2, and then the mobile box 52 is moved to the top of the cleaning box 53 through the extension and contraction of the electric push rod B51, and then the air pump 59 blows the sponge block 58 and the cutter head 6 through the annular air pipe 592 and the air jet 593, so as to help remove the residues in the vacant cutter head slot 56 and on the outer surface of the cutter head 6, thereby reducing manual intervention and improving the efficiency of tool changing.

[0027] The inner wall of each group of cutter head grooves 56 is provided with a spring 561, and two groups of springs 561 are provided. A clamping block 562 is provided at one end of each group of springs 561, and one side of each group of clamping blocks 562 is connected to one side of the sponge block 58. Through the springs 561 and the clamping blocks 562, cutter heads 6 of different sizes can be accommodated, thereby improving the cleaning effect of the sponge block 58 on the cutter head 6.

[0028] An oiling assembly 7 is provided inside the cleaning box 53. The oiling assembly 7 includes a micro oil pump 71 arranged on one side of the workbench 1, and an oil pipe 72 fixedly installed at one end of the micro oil pump 71. Two groups of oil pipes 72 are provided. An annular oil pipe 73 is provided at one end of one group of oil pipes 72. Oil mist nozzles 74 are provided on the outer surface of the annular oil pipe 73. There are six groups of oil mist nozzles 74, all facing the direction of the cutter head 6. An oil tank 75 is provided at one end of the other group of oil pipes 72. The micro oil pump 71 transports the lubricating oil in the oil tank 75 to the annular oil pipe 73 and the oil mist nozzle 74 through the oil pipe 72, so as to evenly spray lubricate the cutter head 6, thereby reducing tool wear and extending the service life.

[0029] A filter screen 521 is provided at the bottom of the movable box 52, so as to filter out impurities falling off from the cutter head 6 or the sponge block 58 during the cleaning process, which not only facilitates the oiling component 7 to spray oil from the bottom, but also prevents debris from falling onto the workbench 1 during the movement.

[0030] A baffle 531 is provided on the upper surface of the cleaning box 53, and the bottom of the air pump 59 is connected to the upper surface of the baffle 531, which not only provides support for the air pump 59, but also can prevent oil mist and debris from overflowing during the oiling and blowing process, thereby maintaining the working environment.

[0031] A protective cover 541 is provided on the outer surface of the motor 54 to protect the motor 54 from lubricating oil, debris, etc., thereby increasing the service life of the motor 54.

[0032] Specifically, the data processing center body and the tool changing assembly in the device are both prior art and belong to the technical scope familiar to those skilled in the art, so they are not described again. First, the motor 54 drives the rotating shaft 55 and the tool storage tray 4 to rotate, so that the tool changing assembly can replace the required cutter head 6. When the used cutter head 6 is put back into the cutter head slot 56, since the inner wall of each group of cutter head slots 56 is provided with a spring 561, a clamping block 562 and a sponge block 58, not only can the sponge block 58 be used to clean the debris on the cutter head 6, but also can adapt to cutter heads 6 of different sizes. Then, the L-shaped plate 3 is located at the position of the cleaning box 53 by the extension and contraction of the electric push rod A2, and then the mobile box 52 is moved to the top of the cleaning box 53 by the extension and contraction of the electric push rod B51. Then, the air pump 59 blows the sponge block 58 and the cutter head 6 through the annular air pipe 592 and the jet head 593, thereby helping to remove the residues in the vacant cutter head slot 56 and on the outer surface of the cutter head 6, thereby reducing manual intervention and improving the tool changing efficiency. An oiling assembly 7 is provided inside 53, so the micro oil pump 71 transports the lubricating oil in the oil tank 75 to the annular oil pipe 73 and the oil mist nozzle 74 through the oil pipe 72, so as to evenly spray lubricate the cutter head 6, thereby reducing tool wear and extending the service life. Because a filter screen 521 is provided at the bottom of the movable box 52, impurities that fall off from the cutter head 6 or the sponge block 58 during the cleaning process can be filtered out, which not only facilitates the oiling assembly 7 to spray oil from the bottom, but also prevents debris from falling onto the workbench 1 during the movement, which is convenient for subsequent cleaning. In addition, a protective cover 541 is provided on the outer surface of the motor 54, so that the motor 54 can be protected from lubricating oil, debris, etc., and the service life of the motor 54 is increased. In addition, a baffle 531 is also provided on the upper surface of the cleaning box 53 in the above structure, and the bottom of the air pump 59 is connected to the upper surface of the baffle 531, which not only provides support for the air pump 59, but also can prevent oil mist and debris from overflowing during the oiling and blowing process, thereby maintaining the working environment.
