Description

Technical Field

[0001] This utility model relates to the field of CNC milling machine technology, specifically a CNC milling machine that facilitates the cooling of the milling cutter. Background Technology

[0002] CNC milling machines are milling machines equipped with computer numerical control systems. They are the most widely used high-precision machining equipment in modern machinery manufacturing. They can automatically perform machining according to pre-programmed procedures and are suitable for machining various complex parts. Milling cutters are cutting tools used to machine various metal and non-metal materials and are widely used in CNC milling machines. They are usually made of high-speed steel, cemented carbide, or other materials to ensure stability and durability under different machining conditions. During the milling process, friction occurs when the milling cutter comes into contact with the workpiece, resulting in high temperatures. If the milling cutter temperature is too high, its hardness or shape accuracy may be reduced due to material fatigue or thermal deformation, shortening the tool life. Therefore, cooling the milling cutter is necessary to ensure machining quality and efficiency, extend tool life, and ensure machining safety.

[0003] Chinese Patent Publication No. (CN213004133U) discloses a CNC milling machine capable of water cooling of milling cutters, including an operating table. A water storage tank is fixedly connected to the top of the operating table, a filter box is fixedly connected to the top of the water storage tank, a working frame is fixedly connected to the top of the filter box, a fixed frame is fixedly connected to the top of the operating table, a milling cutter assembly is fixedly connected to the inner wall of the fixed frame, movable seats are fixedly connected to both sides of the inner wall of the fixed frame, and a water pump is fixedly connected to both sides of the top of the operating table.

[0004] The aforementioned comparative document mainly describes a process where water is added to the work frame, pumped through a water pump to an outlet pipe, and then passed to a nozzle and atomizing nozzle to spray water onto the milling cutter and workpiece for cooling. Wastewater is then collected in the work frame and transported to a filter box via a first water pipe. After being filtered by a filter screen, the wastewater flows back to the storage tank via a second water pipe for recycling. However, when the milling cutter rotates at high speed to cut the workpiece, it generates a large amount of iron filings. These iron filings may accumulate in the work frame, affecting the water return speed. Over time, this may also cause blockage of the first water pipe, affecting the normal operation of the water circulation cooling system.

[0005] In view of this, the present invention solves the above-mentioned technical problems by proposing a CNC milling machine that facilitates the cooling of the milling cutter. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a CNC milling machine that facilitates cutter cooling. This CNC milling machine, through the design of a chip removal component, effectively solves the problem of iron filings generated during high-temperature cutting. During operation, the generated iron filings fall onto the top of the interception mesh. A servo motor-driven pusher plate rotates, pushing the iron filings into a rectangular groove. Then, a slant plate and guide plate guide the iron filings into the waste bin, keeping the top of the interception mesh unobstructed and preventing iron filings from clogging the mesh screen. Inside the lower housing, the servo motor's stirring blades further ensure that water and pre-prepared cutting fluid are fully mixed to form a suitable concentration and are kept in circulation. Simultaneously, an air pump draws air into the ventilation duct and sprays it out, blowing air to defog the protective glass inside the protective door cavity, effectively preventing water mist formation and ensuring that the user can clearly observe the processing process.

[0026] Please see Figure 1-5As shown, a CNC milling machine for facilitating milling cutter cooling includes a lower housing 1, a milling machine body 101, a spraying assembly 102, and a worktable 103. A chip removal assembly is fixedly connected to the inner cavity of the lower housing 1. The chip removal assembly includes an intercepting mesh 2, which intercepts iron filings generated during machining.

Rectangular grooves 201 can be provided on the top of the intercepting mesh 2 and on one side of the lower housing 1. These rectangular grooves 201 receive iron filings pushed by a pusher plate 205. An inclined plate 202 is fixedly connected to the inner cavity of the rectangular groove 201. The inclined plate 202 is inclined... The inclined angle allows the iron filings to roll into the guide plate 203 after falling into the inclined plate 202, and finally be discharged into the waste bin 207. A guide plate 203 is fixedly connected to one side of the lower housing 1. The guide plate 203 guides the iron filings smoothly into the inner cavity of the waste bin 207. A servo motor 204 is fixedly connected inside the lower housing 1. The servo motor 204 drives the pusher plate 205 and the stirring blade 206 to rotate. Multiple pusher plates 205 are fixedly connected to the surface of the servo motor 204 above the rotating interceptor net 2. There are four pusher plates 205, arranged in a cross shape, fixed to the output shaft surface of the servo motor 204. Driven by the servo motor 204, the 5 rotates, pushing the iron filings on top of the interceptor net 2 towards the rectangular groove 201. Multiple stirring blades 206 are fixedly connected to the surface of the servo motor 204 below the pusher plate 205. These stirring blades 206 are used to stir the water and cutting fluid at the bottom of the inner cavity of the lower housing 1. A waste bin 207 is provided on one side of the lower housing 1, primarily for storing and collecting iron filings. An upper housing 3 is fixedly connected to the top of the lower housing 1, and a protective door 301 is rotatably connected to the surface of the upper housing 3. An air pump 302 is fixedly connected to the top of the upper housing 3, used to extract air. A ventilation pipe is fixedly connected to one end of the air pump 302. 303. A ventilation pipe 303 is provided, which is mainly used to transmit air. Ventilation pipes 304 are provided on the top of the upper housing 3 and the rear surface of the protective door 301. These ventilation pipes 304 are mainly used to transmit air and to blow air out to defrost the protective glass installed inside the protective door 301. One end of the ventilation pipe 303 is connected to one end of the ventilation pipe 304. The milling machine body 101 and the worktable 103 are both fixedly connected to the inner cavity of the lower housing 1. A clamp 4 is bolted to the top of the worktable 103. The clamp 4 is mainly used to clamp parts. Circulation pipes 5 are provided on the other side of both the lower housing 1 and the upper housing 3. A circulation pump 501 is fixedly connected to the other side of the lower housing 1.The output end of the circulating pump 501 is fixedly connected to a circulating pipe 502. The input end of the circulating pump 501 and one end of the circulating pipe 502 are respectively connected to one end of the circulating pipeline 5. The screen hole diameter of the intercepting net 2 is 1-5 mm to ensure that iron filings are effectively intercepted while water flows smoothly into the bottom of the lower housing 1. The push plate 205 and the stirring blade 206 are made of stainless steel to ensure sufficient strength and corrosion resistance. The inclined plate 202 and the guide plate 203 have an inclination angle of 30-45 degrees to ensure that iron filings can smoothly roll into the inner cavity of the waste bin 207. Universal wheels 6 are fixedly connected to the four corners of the bottom of the waste bin 207. The universal wheels 6 are mainly used to facilitate the movement of the waste bin 207. A push handle 601 is fixedly connected to the surface of the waste bin 207. The push handle 601 is mainly used to facilitate pushing and pulling the waste bin 207.

[0027] During use, when the milling machine body 101 processes the parts held by the fixture 4, the generated iron filings will fall into the top of the intercepting net 2 through the inner cavity of the lower housing 1. Then, the servo motor 204 is started, and the servo motor 204 drives the push plate 205 to rotate. The rotation of the push plate 205 pushes the iron filings on the top of the intercepting net 2 towards the rectangular groove 201. When the iron filings reach the rectangular groove 201, they fall onto the inclined plate 202 through the rectangular groove 201. Due to the inclination angle of the inclined plate 202, the iron filings roll onto the guide plate 203 and are discharged into the waste bin 207. Meanwhile, the cooling water will flow into the bottom of the inner cavity of the lower housing 1 through the sieve holes of the intercepting net 2 for circulation. At the same time, the servo motor 204 will also drive the stirring blade 206 to rotate, stirring the water and cutting fluid at the bottom of the inner cavity of the lower housing 1. At this time, the user can pour the original cutting fluid into the inner cavity of the lower housing 1 and add the cutting concentrate to the appropriate concentration while stirring.

[0028] When it is necessary to blow air to defog the protective glass installed inside the protective door 301, the air pump 302 is started. The air pump 302 draws air into the ventilation pipe 303. The air enters the ventilation pipe 303 through the ventilation pipe 303 and then sprays out from the ventilation pipe 304 to blow air onto the protective glass installed inside the protective door 301. By blowing air, water mist is prevented from forming on the surface of the protective glass, ensuring that the user can clearly observe the processing of the parts.

[0029] When it is necessary to cool down the milling cutter of the milling machine body 101, the circulation pump 501 is started. The circulation pump 501 draws cooling water from the inner cavity of the lower housing 1 through the circulation pipe 5. At this time, the cooling water enters the inner cavity of the circulation pipe 502 through the circulation pipe 5 and the circulation pump 501, and then enters the circulation pipe 5 and the spray assembly 102 of the upper housing 3 through the circulation pipe 502. At this time, the spray assembly 102 sprays the cooling water onto the surface of the milling cutter and the workpiece to cool them down.
