[0026] The turntable seat 2 of this embodiment is located at the center of the support seat 1, and multiple hollow rotating tables 3 are evenly distributed on it. Each rotating table can independently accommodate a tool 7 and has the function of driving the tool 7 to rotate. A transmission mechanism 6 is installed between the support seat 1 and the turntable seat 2. This mechanism is responsible for controlling the rotation of the entire turntable seat 2. It can enable the turntable seat 2 to rotate relative to the support seat 1 according to the program settings of the numerical control system or the information fed back by the sensor, so as to facilitate the positioning of the hollow rotating tables 3 and the tools 7 carried by them at different positions to the preset working positions. After cleaning is completed, the next tool 7 to be cleaned is rotated to the cleaning area. The cleaning mechanism 4 is installed in any direction of the support seat 1. When a specific tool 7 needs to be cleaned, the transmission mechanism 6 is first controlled by the numerical control system to rotate the corresponding rotating table and tool 7 to the position of the cleaning mechanism 4, thereby achieving precise positioning of the tool 7. Subsequently, the hollow rotating table 3 is used to rotate the tool 7 placed therein in a circumferential direction, thereby ensuring that the tool 7 can be thoroughly cleaned from all angles to improve the cleaning effect. The cleaning mechanism 4 is connected to a lifting mechanism, which allows the height of the cleaning head to be adjusted to ensure that the area to be cleaned by the tool 7 can be accurately covered, and the cleaning mechanism 4 can be lowered to a position that does not affect the rotation of the tool 7.

The support collar is located at the center of the hollow turntable 3 and is provided with a slot capable of receiving and fixing the handle of the cutting tool 7, which is used to fix and support the cutting tool 7 and ensure its stability during rotation. The first drive motor 34 is a servo motor controlled by a numerical control system, providing rotational power to the hollow turntable 3 to adjust the rotation speed of the cutting tool 7. The driving gear 33 is mounted on the rotating shaft 46 of the first drive motor 34, and the driven gear 32 is integrally mounted on the outer wall of the support collar and meshes with the driving gear 33. When the driving gear 33 is driven, the driven gear 32 rotates accordingly, driving the support collar 31 and the cutting tool 7 to rotate together.

[0028] like Figure 2As shown, the cleaning mechanism 4 of the embodiment includes a mounting seat 41, an electric double-end push rod 42 arranged inside the mounting seat 41, two connecting arms 43 respectively hinged to the two free ends of the electric double-end push rod 42, and cleaning clamping plates 44 fixed to the other ends of the connecting arms 43, the inner walls of the two cleaning clamping plates 44 are attached with cleaning sponges 45, and a rotating shaft 46 movably arranged on the connecting arm 43 is arranged in the mounting seat 41.

The other end of the connecting arm 43 is fixed with the cleaning clamping plate 44, and the two cleaning clamping plates 44 are attached with the cleaning sponges 45 on one surface, and a cleaning brush can also be added. The electric double-end push rod 42 can adjust the distance between the two connecting arms 43 through telescopic action, so that the two cleaning clamping plates 44 are attached or separated. When the tool 7 needs to be cleaned and rotates into the cleaning area, the cleaning clamping plates 44 are in an open state. The cleaning mechanism 4 is lifted to a certain height by the lifting mechanism, so that the tool 7 is located between the open cleaning clamping plates 44, and then the cleaning clamping plates 44 are driven by the electric double-end push rod 42 to be closed to clamp the tool 7, and then the tool 7 is rotated by the hollow rotating platform to cooperate with the cleaning sponge 45 inside the cleaning clamping plate 44 to automatically and circumferentially clean the tool 7.

In this way, it can be ensured that the cuttings, oil stains and other impurities falling off the surface of the tool 7 during cleaning can directly fall into the sludge collecting tank 47.

[0031] As shown in the figure, Figure 1As shown, the transmission mechanism 6 of the embodiment includes a second driving motor 61 fixed on the bearing seat 1 and a speed reducer 62 installed on the output end of the second driving motor 61. The second driving motor 61 is a servo motor controlled by a numerical control system, and the combination of the second driving motor 61 and the speed reducer 62 can provide precise rotation control. The speed reducer 62 can reduce the rotation speed of the output end of the motor and increase the torque, so that the rotation of the rotary table seat 2 is more stable and accurate.

[0032] In summary, the rotary table seat 2 of the embodiment is located at the center position of the bearing seat 1, and a plurality of hollow rotary tables 3 are uniformly distributed thereon.

The numerical control system can accurately control the rotation of the rotary table seat 2 according to the program setting or the information fed back by the sensor, and position the tool 7 to be cleaned to the cleaning area. The cleaning mechanism 4 including the mounting seat 41, the electric double-headed push rod 42, the connecting arm 43 and the cleaning clamp plate 44, the electric double-headed push rod 42 adjusts the distance between the two connecting arms 43 through the extension and retraction action, so that the cleaning clamp plate 44 can be close to or away from the tool 7. The cleaning sponge 45 (or brush) is attached to the inner wall of the cleaning clamp plate 44 for cleaning the surface of the tool 7. The lifting structure 5 including the fixing seat 51, the lifting cylinder 52 and the lifting plate 53, the lifting cylinder 52 drives the lifting plate 53 to move up and down through the extension and retraction action, so as to change the height of the cleaning mechanism 4, so that it can accurately cover the tool 7 to be cleaned. The collecting tank 47 is arranged on the end face of the bearing seat 1 and located below the two cleaning clamp plates 44, which is used for collecting the cuttings and oil stains falling during the cleaning process and keeping the working area clean.
