Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically to a CNC gantry milling machine with a cooling device. Background Technology

[0002] Numerical control machining is one of the core technologies of modern manufacturing. It uses computer programs to control the movement and operation of machine tools to achieve high-precision and high-efficiency machining of complex parts. When machining larger workpieces, gantry milling machines are required. During machining, the friction between the milling cutter and the workpiece can easily generate high temperatures, requiring cooling of both the milling cutter and the workpiece. This necessitates the use of CNC gantry milling machines equipped with cooling devices.

[0003] The existing technology has the following problems:

[0004] When cooling the milling cutter on a gantry milling machine, coolant is usually sprayed onto the cutter for cooling. After cooling, the workpiece debris and coolant generated during machining flow into the chamber, and then the coolant is sprayed back onto the cutter for recycling. To separate the coolant from the debris, a filter screen is usually installed inside the chamber to intercept the debris. When the mesh size of the filter screen is large, smaller debris can easily fall through the filter screen downwards. When the mesh size of the filter screen is small, it can affect the efficiency of the coolant penetrating downwards, and it is also not convenient to automatically discharge and collect the separated debris, nor is it convenient to clean the debris adhering to the surface of the filter cloth. Utility Model Content

[0005] The purpose of this invention is to provide a CNC gantry milling machine with a cooling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC gantry milling machine with a cooling device, comprising a gantry frame, a milling cutter, and a nozzle, characterized in that: the gantry frame is slidably mounted above a fixed box; a milling cutter is movably mounted on the inner side of the gantry frame; a nozzle is fixedly connected to the front side of the milling cutter; a support plate is fixedly mounted on the inner side of the fixed box below the support plate; a filter cloth is rotatably mounted on the inner side of the fixed box below the support plate via a conveying roller; one end of the filter cloth extends out of one side of the fixed box; a fixed plate is fixedly mounted on the inner side of the fixed box below the filter cloth; and the bottom of the fixed plate is fixedly connected to... The device has heat dissipation fins. A fixing frame is fixedly installed between one end of the fixing plate and the fixing box. A delivery pump is fixedly connected to the inner side of the fixing frame. A spring tube is fixedly connected between the output end of the delivery pump and the nozzle. A fan is fixedly installed inside the fixing box behind the delivery pump. A support roller is rotatably connected to one side of the fixing box via a support frame. The delivery roller is located inside the filter cloth and provides rolling support for the filter cloth. A roller is rotatably installed at the bottom of the support frame via a fixing rod. A brush is fixedly connected to the outer periphery of the roller. A cleaning frame is fixedly installed inside the fixing rod, and the brush extends to the inner side of the cleaning frame.

[0007] By placing the workpiece on top of the support plate, the gantry crane moves the milling cutter to machine the workpiece. Coolant is introduced into a fixed tank and pumped through a spring tube to the nozzles, which spray the coolant onto the milling cutter to cool it. The coolant then flows downwards through the support plate, causing machining debris to fall below the support plate and onto the top of the filter cloth. Conveyor rollers roll the filter cloth, causing the top of the cloth to move to the right, collecting and removing debris for automatic separation. A fan exhausts air from one side of the fixed tank while introducing outside air from the other side, allowing the introduced air to pass through multiple... The heat dissipation fins flow to the right on the inner side, absorbing heat from the coolant and transferring it to the air, which is then discharged outside the fixed box. This cooling process facilitates the recycling of the coolant. As the filter cloth rotates, it drives the support roller to rotate synchronously. Belt drive allows the support roller to rotate synchronously with the drum, which in turn rotates the brush. This causes the brush at the top of the drum to flip to the right. When conveying debris, the bottom of the filter cloth moves to the left, and the brush at the top of the drum flips to the right, sweeping away debris adhering to the filter cloth surface. This automatic cleaning of the filter cloth is achieved. The cleaning frame then scrapes off debris adhering to the brush, causing it to fall downwards along one side of the cleaning frame.

[0008] Preferably, an air inlet slot is provided on one side of the fixed box, and the air inlet slot is located at one end of the fixed frame. The air inlet slot allows outside air to be introduced into the fixed box.

[0009] Preferably, a motor is fixedly mounted on the front side of the fixed box, and the output end of the motor is fixedly connected to the shaft of a conveyor roller. The motor can drive the conveyor roller to rotate.

[0010] Preferably, the roller and the support roller are rotatably connected by a belt, which is located in front of the support frame and the fixed rod. The belt allows the support roller to drive the roller to rotate.

[0011] Preferably, multiple support rods are fixedly installed at the bottom of the support plate, and both ends of the multiple support rods are fixedly connected to the inner wall of the fixed box. The support rods can improve the strength of the support plate.

[0012] Preferably, a support wheel is rotatably mounted on the inner side of the fixed box, one end of the filter cloth is bent upwards, and the support wheel is located on top of the filter cloth and provides rolling support to the bent portion of the filter cloth. The support wheel provides rolling support to the top of the conveyor belt.

[0013] Preferably, a suction pipe is fixedly installed between the input end of the delivery pump and the fixed frame, and one end of the suction pipe is connected to the outside of the fixed frame. The suction pipe allows the delivery pump to draw out the coolant from the fixed box.

[0014] Preferably, an exhaust pipe is fixedly connected between the output end of the fan and the fixed box, with one end of the exhaust pipe connected to the output end of the fan and the other end connected to the outside of the fixed box. The exhaust pipe allows the fan to expel air from inside the fixed box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By employing the interplay between nozzles, filter cloth, and heat dissipation fins, the workpiece is placed on top of a support plate. A gantry frame moves the milling cutter to process the workpiece. Coolant is introduced into a fixed tank, ensuring its level is higher than the conveyor rollers. A pump draws out the coolant, which is then delivered to the nozzles via a spring tube. The nozzles spray the coolant onto the milling cutter, cooling it. The coolant also helps to dislodge machining debris, causing it to fall below the support plate and onto the top of the filter cloth. The conveyor rollers rotate the filter cloth, moving its top to the right to collect the debris. The system automatically separates and removes debris. A fan exhausts air from one side of the fixed box, while introducing outside air from the other side. The air entering the fixed box flows to the right through the inner side of multiple heat dissipation fins. These fins absorb heat from the coolant and transfer it to the air for dissipation, thus cooling the coolant. As the coolant flows downward through the support plate, the rotation of the conveyor rollers and filter cloth promotes mixing and circulation within the box. This prevents the coolant from failing to transfer heat to the heat dissipation fins, facilitating the recycling of the coolant.

[0017] 2. Through the cooperation of the support roller, drum, brush and cleaning frame, the filter cloth rotates, which drives the support roller to rotate synchronously. The belt drive enables the support roller to rotate synchronously, which in turn drives the brush to rotate. The brush at the top of the drum can be flipped to the right. When the filter cloth is conveying debris, the bottom of the filter cloth can be moved to the left. The brush at the top of the drum flips to the right, which can sweep off the debris adhering to the surface of the filter cloth. The filter cloth can be cleaned automatically. The cleaning frame can scrape off the debris adhering to the brush, and the debris falls down along one side of the cleaning frame. Attached Figure Description

A heat dissipation fin 18 is fixedly connected to the bottom of the fixed plate 17. One end of the fixed plate 17 is connected to the fixed box 1. A fixed frame 19 is fixedly installed between the nozzles. A conveying pump 20 is fixedly connected to the inner side of the fixed frame 19. A spring tube 6 is fixedly connected between the output end of the conveying pump 20 and the nozzle 5. A fan 25 is fixedly installed inside the fixed box 1 behind the conveying pump 20. A support roller 11 is rotatably connected to one side of the fixed box 1 via a support frame 10. The conveying roller 8 is located inside the filter cloth 13 and provides rolling support for the filter cloth 13. A roller 22 is rotatably installed at the bottom of the support frame 10 via a fixed rod 12. A brush 23 is fixedly connected to the outer periphery of the roller 22. A cleaning frame 24 is fixedly installed inside the fixed rod 12. The brush 23 extends to the inner side of the cleaning frame 24.

[0026] An air inlet slot 7 is provided on one side of the fixed box 1, and the air inlet slot 7 is located at one end of the fixed frame 19;

[0027] A motor 9 is fixedly installed on the front side of the fixed box 1, and the output end of the motor 9 is fixedly connected to the shaft of a conveying roller 8;

[0028] The roller 22 is rotatably connected to the support roller 11 via a belt 14, which is located in front of the support frame 10 and the fixing rod 12.

[0029] Multiple support rods 15 are fixedly installed at the bottom of the support plate 2, and both ends of the multiple support rods 15 are fixedly connected to the inner wall of the fixed box 1.

[0030] A support wheel 16 is rotatably mounted on the inner side of the fixed box 1. One end of the filter cloth 13 is bent upwards. The support wheel 16 is located on the top of the filter cloth 13 and provides rolling support for the bent part of the filter cloth 13.

[0031] A suction pipe 21 is fixedly installed between the input end of the delivery pump 20 and the fixed frame 19, and one end of the suction pipe 21 is connected to the outside of the fixed frame 19.

[0032] An exhaust pipe 26 is fixedly connected between the output end of the fan 25 and the fixed box 1. One end of the exhaust pipe 26 is connected to the output end of the fan 25, and the other end of the exhaust pipe 26 is connected to the outside of the fixed box 1.

[0033] The working principle of the CNC gantry milling machine with cooling device based on the embodiment is as follows: by placing the workpiece on the top of the support plate 2, the gantry frame 3 is used to move the milling cutter 4 and process the workpiece. By introducing coolant into the fixed tank 1, the level of coolant is made higher than that of the conveying roller 8. The conveying pump 20 is used to draw out the coolant through the suction pipe 21. Then, the coolant is transported to the nozzle 5 through the spring tube 6. The nozzle 5 sprays the coolant onto the milling cutter 4 to cool the milling cutter 4. Then, the coolant flows downward through the support plate 2.

[0034] The coolant can cause the debris generated during processing to fall below the support plate 2 and fall to the top of the filter cloth 13. The motor 9 can drive the conveying roller 8 to rotate, and the conveying roller 8 can roll and convey the filter cloth 13. This can cause the top of the filter cloth 13 to move to the right, so that the debris can be discharged and collected, which facilitates the automatic separation and discharge of the debris.

[0035] The fan 25 can exhaust the air inside the fixed box 1 through one side, allowing outside air to be introduced into the fixed box 1 through the air inlet 7. The air introduced into the fixed box 1 can flow to the right through the inner side of multiple heat dissipation fins 18. The heat dissipation fins 18 can absorb the heat of the coolant and then transfer the heat to the air and out of the fixed box 1, which can dissipate heat and cool the coolant. When the coolant flows downward through the support plate 2, the rotation of the conveying roller 8 and the filter cloth 13 can drive the coolant in the fixed box 1 to circulate and mix, preventing the coolant containing heat from failing to transfer heat to the heat dissipation fins 18, and facilitating the recycling of the coolant.

[0036] When the filter cloth 13 rotates, it can drive the support roller 11 to rotate synchronously. Through the belt 14, the support roller 11 can drive the roller 22 to rotate synchronously, and the roller 22 can drive the brush 23 to rotate. The brush 23 at the top of the roller 22 can be flipped to the right. When the filter cloth 13 is conveying debris, the bottom of the filter cloth 13 can be moved to the left. By flipping the brush 23 at the top of the roller 22 to the right, the debris adhering to the surface of the filter cloth 13 can be swept off, and the filter cloth 13 can be automatically cleaned. The cleaning frame 24 can scrape off the debris adhering to the brush 23, and the debris falls down along one side of the cleaning frame 24.

[0037] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
