[0002] CNC milling machines are a type of automated machining equipment developed from conventional milling machines. They share essentially the same machining process and somewhat similar structures. CNC milling machines are categorized into two main types: those without a tool magazine and those with one. CNC milling machines with a tool magazine are also known as machining centers.

[0003] A large amount of iron chips will be generated when using CNC milling machines, and driven by the high speed of the spindle, the iron chips will also be picked up by the high-speed rotation. However, the current practical CNC milling machines do not have effective protective devices to reduce the harm to workers caused by the flying of iron chips and parts. There are no regular collection and cleaning devices. Directly collecting iron chips and cleaning the iron chips generated by milling machine processing is also a considerable task, and the collection efficiency is low. In addition, there is a lack of cleaning of the workbench on the CNC milling machine, which affects subsequent assembly. Summary of the Invention

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is an automatic chip cleaning system for a CNC milling machine, comprising a frame 1 and a workbench 19, wherein a first panel 18 and a second panel 21 are respectively installed at both ends of the workbench 19, and the frame 1 is installed on the outside of the workbench 19, the first panel 18 and the second panel 21, and the frame 1, the workbench 19, the first panel 18 and the second panel 21 are combined to form a water storage chamber, and a baffle 3 covering the water storage chamber is provided on the opening of the frame 1, and a pull plate 4 is installed at one end of the baffle 3, and a pressure plate 5 for pressing the baffle 3 and the pull plate 4 is installed on both sides of the frame 1 through a hinge, and a cleaning mechanism connected to the water storage chamber is installed on the outside of the frame 1.

[0023] In this embodiment, the cleaning mechanism includes a circulation pipe 15, a main pipe 11, a liquid injection pipe, a first valve 12, a second valve 14, a water pump 13, a liquid inlet pipe and multiple liquid outlet pipes 10, one end of the liquid outlet pipe 10 is installed on the main pipe 11, and the other end is installed on one end of the frame 1, and is connected to the water storage chamber, one end of the liquid inlet pipe is installed on the main pipe 11, the first valve 12 and the water pump 13 are installed on the liquid inlet pipe, one end of the circulation pipe 15 is installed on the frame 1 and is arranged away from the main pipe 11, the other end of the circulation pipe 15 is installed on the liquid inlet pipe, and the second valve 14 is installed on the liquid inlet pipe.

[0024] In this embodiment, a shell 6 is installed on both sides of the frame 1. A plurality of air outlet holes communicating with the shell 6 are provided on the inner side of the frame 1. An air inlet pipe 8 is installed at one end of the shell 6.

[0025] A plurality of fixing parts 9 are protruded from the outer surface of the pressure plate 5 , each of which is provided with a first screw hole. A plurality of second screw holes are provided on the shell 6 , and hand bolts 7 are threadedly connected in the corresponding first screw holes and second screw holes.

[0026] In this embodiment, the first panel 18 and the second panel 21 are arranged one above and one below, and the filter frame 17 is placed on the second panel 21; wherein, the bottom surface of the second panel can be installed with a drain pipe 9 (not shown) connected to the water storage chamber, and a third valve is installed on the drain pipe. After flushing is completed, the internal metalworking fluid can be discharged along the drain pipe, and a drying operation can be performed after discharge.

[0027] In this embodiment, positioning grooves are provided at both ends of the pull plate 4, and the inner side surfaces of the pressure plate 5 protrude opposite the positioning grooves to form positioning portions 20, which are inserted into the positioning grooves. The pull plate and the baffle can be positioned after being pulled by plugging the positioning portions and the positioning grooves, thereby avoiding the situation of self-rewinding.

[0028] In this embodiment, a winding device 2 for winding up the baffle 3 is installed at one end of the frame 1. The baffle 3 is made of rubber material. The winding device is a reel-type electric winding device in the prior art. Therefore, when the baffle needs to be wound up, the winding device can be started. The winding device can automatically wind the baffle into the inside, so that the baffle is removed from the opening of the frame, so that the workbench can be exposed, thereby not affecting the cutting operation of the workpiece.

[0029] During operation, the hand screws are first screwed out from the first and second screw holes. After the hand screws are no longer blocking the workpiece, the pressing plate can be opened outward with the hinge as the center, thereby preventing the pressing plate from pressing the baffle. The movement of the pressing plate drives the positioning part. After the positioning part moves out of the positioning groove, the baffle can be reeled in by the reeling device. After the baffle is no longer blocking the workpiece, the workpiece table can be exposed to perform cutting operations. During the cutting process, the frame can block iron chips as much as possible.

[0030] When cleaning, the baffle can be pulled out and the pressing plate can be closed. The edge of the baffle and the pulling plate can be pressed by the pressing plate, and the opening of the frame can be covered by the baffle;

[0031] After the above is completed, prepare a hose. One end of the hose is connected to the liquid inlet pipe, and the other end is immersed in the box storing the metalworking fluid. After opening the first valve, the metalworking fluid can be injected into the water storage chamber along the main pipe and the liquid outlet pipe through the water pump. Since the opening of the water storage chamber is blocked, the impact force can be increased. By flushing from left to right, the iron chips can be taken away and enter the filter frame, while removing the iron chips and cleaning the workbench.

[0032] Among them, after a certain amount of metalworking fluid is injected, the first valve can be closed and the second valve can be opened. The metalworking fluid can be continuously circulated inside the water storage chamber through the circulation pipe, which can increase the continuity of flushing to ensure the quality of cleaning.

[0033] Among them, after cleaning is completed, a hot air heater can be prepared. The hot air heater can be connected to the air inlet pipe through a hose, so that the hot air generated by the hot air heater can enter the shell along the air inlet pipe until it is discharged from the air outlet. The discharged hot air can dry the workbench to increase the practicality of the work.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
