Description

Technical Field

[0001] The utility model relates to the field of laser plate cutting machines, in particular to a four-axis numerical control milling machine with circulating cooling. Background Art

[0002] The numerical control milling machine is the main production device for various metal workpieces at present. Among them, the laser plate cutting machine is a kind of numerical control milling machine. It is a machine device that uses a laser beam with a high energy density to cut plates. Since the cutting head part of the laser plate cutting machine will generate high temperature during operation, the continuous high temperature will cause damage to the equipment, reduce the cutting accuracy, and shorten its service life. Therefore, a device with circulating cooling is generally equipped on this equipment;

[0003] At present, the circulating cooling of the laser plate cutting machine mainly depends on the water cooling system. The water in the water tank is continuously pumped into the water pipe by a water pump, and the heat is carried away by the water to complete the cooling work of the laser plate cutting machine.

[0004] In the existing circulating cooling device during use, the water in the water pipe will re-enter the water tank. After the water in the water pipe completes cooling, its heat will rise. During continuous operation, it will cause the water temperature in the water tank to increase, resulting in a reduction in the subsequent cooling effect and affecting the normal circulating cooling work.

[0005] Therefore, it is necessary to provide a new four-axis numerical control milling machine with circulating cooling to solve the above technical problems. Summary of the Utility Model

[0006] To solve the above technical problems, the utility model provides a four-axis numerical control milling machine with circulating cooling.

[0007] The four-axis numerical control milling machine with circulating cooling provided by the utility model includes a machine body. A cross beam is slidably connected to the machine body. A load-bearing seat is slidably connected to the cross beam. The bottom of the load-bearing seat is fixedly connected with a telescopic seat. The bottom of the telescopic seat is fixedly connected with a cutting head. A water tank is fixedly connected to the load-bearing seat. A plurality of heat dissipation holes are provided at the top of the water tank. A circulating water pipe is fixedly connected between the bottom and the top of the water tank. Two stirring paddles rotatably connected are installed in the water tank.

[0008] Preferably, two pulleys rotatably connected are installed at the top of the water tank. The bottoms of the pulleys are fixedly butted with the tops of the stirring paddles on the same side. A transmission belt is provided between the pulleys.

[0009] Preferably, a water pump is fixedly connected to the bottom of the water tank. The water pump is fixedly butted with the circulating water pipe. The middle section of the circulating water pipe is spirally sleeved outside the cutting head.

[0010] Preferably, one side of the load-bearing seat is fixedly connected with a fixing frame, and two rotatably connected lead screws are installed between the fixing frames. The lead screws are both threadedly connected with mounting seats. The mounting seats are both fixedly connected with limiting rods, and the limiting rods are all slidably connected with the inner walls of the fixing frames. The circulating water pipe is located between the two limiting rods. Two meshing gears are rotatably connected to one side of the fixing frame. The gears are both fixedly butted with one end of the lead screw on the same side. A knob is rotatably connected to the other side of the fixing frame, and the knob is fixedly butted with the end of the lead screw on the same side.

[0011] Preferably, a motor is fixedly connected to one side of the top of the water tank through a frame body, and the output end of the motor is fixedly butted with the top of the pulley on the same side.

[0012] Preferably, a water injection hole is provided at the top of the water tank, and a glass plate is fixedly connected to one side of the water tank.

[0013] Preferably, a control box is fixedly connected to one side of the machine body, and a control panel is fixedly connected to the top of the control box.

[0014] Compared with the related art, the circulating cooling four-axis CNC milling machine provided by the present invention has the following beneficial effects:

[0015] 1. When the present invention starts the motor, through the cooperation of the pulley and the transmission belt, two stirring paddles can be driven to stir the water in the water tank, so that the temperature of the water in the water tank is dissipated more quickly. At this time, the temperature in the water tank will be discharged through the heat dissipation holes, completing the cooling work of the water in the water tank, and effectively improving the subsequent circulating water cooling effect.

[0016] 2. By rotating the knob and through the cooperation of the two gears, the two lead screws can be rotated synchronously in opposite directions. At this time, the two limiting rods can be driven by the mounting seats to move in opposite directions. During the movement of the two limiting rods, the circulating water pipe can be pulled, so as to change the distance between the circulating water pipe and the cutting head, and control the efficiency of the circulating water cooling. The auxiliary performance of the device for the circulating cooling work is effectively improved. At the same time, the two limiting rods can also limit and fix the redundant part of the circulating water pipe, improving the protection of the circulating water pipe.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0025] Please refer to Figures 1 to 5 , a circulating cooling four-axis CNC milling machine provided by an embodiment of the present utility model includes a body 1, a cross beam 11 is slidably connected to the body 1, a load-bearing seat 12 is slidably connected to the cross beam 11, and a telescopic seat 13 is fixedly connected to the bottom of the load-bearing seat 12. A cutting head 14 is fixedly connected to the bottom of the telescopic seat 13, a control box 15 is fixedly connected to one side of the body 1, and a control panel 16 is fixedly connected to the top of the control box 15.

[0026] It should be noted that: the body 1 is the main structure of the laser cutting plate CNC milling machine, the cross beam 11 can move along the body 1, and the load-bearing seat 12 can move along the cross beam 11. The cross beam 11 and the load-bearing seat 12 cooperate to change the cutting position of the cutting head 14, and the telescopic seat 13 can be lifted and lowered to control the height of the cutting head 14. The cutting head 14 can be used to perform cutting and processing work on the metal workpiece on the body 1. By cooperating the control box 15 and the control panel 16, all the electrical appliances on the device can be controlled, and the operating conditions of the electrical appliances are displayed on the control panel 16.

[0027] In an embodiment of the present utility model, please refer to Figure 2 , Figure 3 and Figure 4, a water tank 2 is fixedly connected to the load-bearing seat 12, and a plurality of heat dissipation holes 22 are provided at the top of the water tank 2. A water injection hole 21 is provided at the top of the water tank 2, and a glass plate 23 is fixedly connected to one side of the water tank 2.

[0028] It should be noted that: through the water injection hole 21, the water tank 2 can be filled with water for cooling. Through the glass plate 23, the staff can more intuitively know the remaining amount of water in the water tank 2, which is convenient for adding water to the water tank 2 in time. The heat dissipation holes 22 can be used for the heat dissipation work of the water in the water tank 2.

[0029] In an embodiment of the present invention, please refer to Figure 2 and Figure 3 , a circulating water pipe 31 is fixedly connected between the bottom and the top of the water tank 2. A water pump 3 is fixedly connected to the bottom of the water tank 2, and the water pump 3 is fixedly docked with the circulating water pipe 31. The middle section of the circulating water pipe 31 is spirally sleeved outside the cutting head 14.

[0030] It should be noted that: when performing workpiece processing work, start the water pump 3, the water in the water tank 2 can be conveyed into the circulating water pipe 31. At this time, the water flows in the circulating water pipe 31 and reflows into the water tank 2 through the other end of the circulating water pipe 31 to complete the water circulation work. When the water flows in the circulating water pipe 31, the temperature generated by the cutting head 14 during work can be taken away. By using the spiral circulating water pipe 31 to increase the water flow formation, the cutting head 14 can be better cooled.

[0031] In an embodiment of the present invention, please refer to Figure 2 , Figure 3 and Figure 4 , two pulley wheels 41 are rotatably connected to the top of the water tank 2, and the bottoms of the pulley wheels 41 are fixedly docked with the tops of the stirring paddles 4 on the same side. A transmission belt 42 is provided between the pulley wheels 41. A motor 43 is fixedly connected to one side of the top of the water tank 2 through a frame body, and the output end of the motor 43 is fixedly docked with the top of the pulley wheel 41 on the same side.

[0032] It should be noted that: turn on the motor 43 to drive the pulley wheel 41 connected thereto to rotate. At this time, this pulley wheel 41 can drive another pulley wheel 41 to rotate through the transmission belt 42. The two rotating pulley wheels 41 can drive the stirring paddles 4 connected to each other to rotate, stirring and surging the water in the water tank 2, accelerating the dissipation of the temperature of the water in the water tank 2. Then, through cooperation with the heat dissipation holes 22, the temperature in the water tank 2 is discharged to control the temperature of the water in the water tank 2 and improve the efficiency of the subsequent circulating cooling work.

[0033] In an embodiment of the present invention, please refer to Figure 2 and Figure 5, one side of the load-bearing seat 12 is fixedly connected with a fixing frame 5, and two rotatably connected lead screws 51 are installed between the fixing frames 5. The lead screws 51 are both threadedly connected with mounting seats 52. The mounting seats 52 are both fixedly connected with limiting rods 53, and the limiting rods 53 are both slidably connected with the inner walls of the fixing frames 5. The circulating water pipe 31 is located between the two limiting rods 53. Two mutually meshing gears 54 are rotatably connected to one side of the fixing frame 5. The gears 54 are both fixedly butted with one end of the lead screw 51 on the same side. A knob 55 is rotatably connected to the other side of the fixing frame 5, and the knob 55 is fixedly butted with the end of the lead screw 51 on the same side.

[0034] It should be noted that: rotate the knob 55 to drive the connected lead screw 51 to rotate. At this time, the lead screw 51 can drive the connected gear 54 to rotate. At this time, the gear 54 can cooperate with another mutually meshing gear 54 to drive another lead screw 51 to rotate in the opposite direction. At this time, the two lead screws 51 rotating in opposite directions can drive the connected mounting seats 52 to move. Since the two lead screws 51 rotate in opposite directions, the two mounting seats 52 and the limiting rods 53 fixed to the mounting seats 52 will also move in opposite directions. At this time, the two limiting rods 53 can pull and tighten the circulating water pipe 31 located between them. During the process of the circulating water pipe 31 being pulled and tightened, due to its shortened length, its diameter of the loop around the cutting head 14 can be reduced, thereby reducing the distance between the circulating water pipe 31 and the cutting head 14, and thus improving the cooling effect on the cutting head 14.

[0035] The working principle of the circulating cooling four-axis CNC milling machine provided by the present utility model is as follows:

[0036] First, install the machine body 1 at a designated position, then power on the device, and through the water injection hole 21, a certain amount of water for cooling can be filled into the water tank 2, and then the processing work can be carried out;

[0037] Place the metal workpiece to be processed on the machine body 1, and then cooperate with the control box 15 and the control panel 16 to control the device. The cross beam 11 can move along the machine body 1, and the load-bearing seat 12 can move along the cross beam 11. The cross beam 11 and the load-bearing seat 12 cooperate to change the cutting position of the cutting head 14, and the telescopic seat 13 can be lifted and lowered to control the height of the cutting head 14. The cutting head 14 can be used to cut and process the metal workpiece on the machine body 1;

[0038] When performing workpiece processing operations, start the water pump 3, which can transport the water in the water tank 2 into the circulating water pipe 31. At this time, the water flows in the circulating water pipe 31 and re-enters the water tank 2 through the other end of the circulating water pipe 31 to complete the water circulation work. When the water flows in the circulating water pipe 31, it can take away the temperature generated by the working cutting head 14 and cool down the cutting head 14;

[0039] During this process, turn on the motor 43 to drive the pulley 41 connected to it to rotate. At this time, the pulley 41 can drive another pulley 41 to rotate through the transmission belt 42. The two rotating pulleys 41 can drive the stirring paddles 4 connected to each other to rotate, stirring and churning the water in the water tank 2, accelerating the dissipation of the temperature of the water in the water tank 2. Then, through cooperation with the heat dissipation holes 22, the temperature in the water tank 2 is discharged to control the temperature of the water in the water tank 2;

[0040] During the operation of the device, the knob 55 can be rotated to drive the screw rod 51 connected to it to rotate. At this time, the screw rod 51 can drive the gear 54 connected to it to rotate. At this time, the gear 54 can cooperate with another meshing gear 54 to drive another screw rod 51 to rotate in the opposite direction. At this time, the two screw rods 51 rotating in opposite directions can drive the mounting seats 52 connected to them to move. Since the two screw rods 51 rotate in opposite directions, the two mounting seats 52 and the limiting rods 53 fixed to the mounting seats 52 will also move in opposite directions. At this time, the two limiting rods 53 can pull and tighten the circulating water pipe 31 located between them. During the process of the circulating water pipe 31 being pulled and tightened, due to its shortened length, its diameter of the loop around the cutting head 14 can be reduced, thereby reducing the distance between the circulating water pipe 31 and the cutting head 14, and thus improving the cooling effect on the cutting head 14.
