Description

Technical Field

[0001] This utility model relates to the field of CNC boring and milling machines, specifically a cooling mechanism for CNC boring and milling machines. Background Technology

[0002] When CNC boring and milling machines process workpieces, they often need to be cooled. Most existing cooling pipes are pre-fixed on the boring and milling cutter holder, with the bottom of the cooling pipe aligned with the cutter head. This method is difficult to adapt to the processing of complex workpieces, especially when processing different workpieces. When changing workpieces, the installation angle of the cooling pipe needs to be manually adjusted, which is quite inconvenient.

[0003] According to the published patent 202221914541.1, a cooling mechanism for a CNC boring and milling machine, it includes a boring and milling head, a guide seat and a cutting head, a support fixedly connected to the guide seat, a rotation adjustment device installed on the support, and an angle adjustment device connected to the rotation adjustment device. A flexible hose and a rigid pipe are combined at the upper end of the cooling pipe, with the rigid pipe clamped and installed. The flexible hose is connected to the cooling equipment, allowing the cooling pipe to adjust its installation angle for easy cooling of the boring and milling workpiece. A first motor drives a U-shaped rod to rotate, causing a second motor and the cooling pipe to adjust the installation angle horizontally. Then, the second motor drives a worm gear and a worm wheel to rotate, and a second gear drives a half-face gear to rotate. Subsequently, a rotating shaft drives the clamped cooling pipe to rotate vertically to adjust the installation angle. This design is convenient to use and adjust. This invention is part of the process of realizing this utility model.

[0004] However, in practice, the cooling mechanism of traditional CNC boring and milling machines uses multiple gears for transmission. Due to the limited size of the U-shaped block, the cooling pipes only move on the surface of the U-shaped block, resulting in a small range of movement. When different parts of the workpiece need to be cooled, this affects the cooling effect. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a cooling mechanism for CNC boring and milling machines. This solves the technical problem that the current traditional cooling mechanism for CNC boring and milling machines uses multiple gears for transmission. Due to the limited size of the U-shaped block, the cooling pipe only moves on the surface of the U-shaped block, and the range of movement of the cooling pipe is small. When different positions of the workpiece need to be cooled, it will affect the cooling effect on the workpiece.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a cooling mechanism for a CNC boring and milling machine is designed, including a base box, a connecting column is installed at the bottom of the base box, a metal heat-conducting plate is fixed at the bottom of the connecting column, a cutting head is installed at the bottom of the metal heat-conducting plate, a support column is fixed at the top of the base box, a U-shaped flow cavity is opened inside the support column, and one end of a plurality of connecting rods is fixed outside the support column, and a cooling component is provided at the other end of the plurality of connecting rods.

[0007] Preferably, the cooling assembly includes an annular electric slide rail, a fixing plate, a water-air dual-purpose pump, a connecting pipe, a hose, a gooseneck tube, and a nozzle.

[0008] Preferably, the inner wall of the annular electric slide rail is fixed with a plurality of connecting rods, one end of the slide rail is slidably connected to the outside of the annular electric slide rail, and the other end of the slide rail is fixed with a fixing plate.

[0009] Preferably, a water-air dual-purpose pump is installed at one end inside the fixed strip, a connecting pipe is connected to the top of the water-air dual-purpose pump, a hose is connected to the bottom of the water-air dual-purpose pump, a nozzle is connected to the other end of the hose, a gooseneck tube passes through the outside of the hose, and one end of the gooseneck tube is fixed to the bottom of the fixed strip.

[0010] Preferably, the base housing has micro-liquid pumps connected to both sides of its bottom, and the bottoms of the two micro-liquid pumps are respectively connected to the top two ends of the U-shaped flow cavity.

[0011] Preferably, the upper and lower sides of the front end of the base box are connected to one end of a liquid pipe, and the other end of the liquid pipe is detachably connected to a pipe cap.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines a ring-shaped electric slide rail, a water-air dual-purpose pump, and a nozzle. Not only can the ring-shaped electric slide rail drive the hose and nozzle to rotate around the workpiece, thereby cooling different parts of the workpiece surface and increasing the cooling range, but the water-air dual-purpose pump can also spray coolant or gas onto the workpiece surface through the nozzle, switching between cooling the workpiece and removing debris, thus improving overall functionality. Furthermore, a gooseneck tube runs through the hose surface, allowing for free adjustment of the hose angle and nozzle position, enhancing the adjustability of the cooling assembly. This solves the technical problem of traditional CNC milling machine cooling mechanisms, which use multiple gears for transmission. Due to the limited size of the U-shaped block, the cooling pipe only moves within the surface of the U-shaped block, resulting in a small range of movement. This limits the cooling effect when different parts of the workpiece need cooling.

[0014] 2. This utility model combines a micro liquid pump, a U-shaped flow chamber, and a metal heat-conducting plate. Two micro liquid pumps can circulate the coolant in the base box within the U-shaped flow chamber in the connecting column. Since a metal heat-conducting plate is provided at the top of the cutter head, the heat of the cutter head can be transferred out by the metal heat-conducting plate and exchanged with the coolant flowing in the U-shaped flow chamber, thereby further cooling the cutter head. In conjunction with the cooling components, the cooling effect can be improved. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: A cooling mechanism for a CNC boring and milling machine, see [link / reference] Figures 1 to 3The system includes a base housing 1, a connecting column 3 installed at the bottom of the base housing 1, a metal heat-conducting plate 301 fixed at the bottom of the connecting column 3, a cutter head 302 installed at the bottom of the metal heat-conducting plate 301, a support column 2 fixed at the top of the base housing 1, a U-shaped flow cavity 304 opened inside the support column 2, and multiple connecting rods 201 fixed at one end of the support column 2. Cooling components are installed at the other ends of the multiple connecting rods 201. During the cooling process of the workpiece, the connecting pipe 206 is first connected to an external conveying pipe. Then, a water-air dual-purpose pump 205 is turned on, using the water-air dual-purpose pump 205 to draw external coolant into a hose 209, which is then sprayed onto the workpiece through a nozzle 208, thereby cooling the workpiece. When it is necessary to blow away debris from the surface of the workpiece, the conveying pipe is removed from the surface of the connecting pipe 206, and the water-air dual-purpose pump 205 is used to directly draw air, which is then sprayed onto the surface of the workpiece through a nozzle 208, thereby cooling the workpiece. The device removes debris from the workpiece surface. During the cooling process, when different parts of the workpiece need to be cooled, the annular electric slide rail 202 can be opened. The annular electric slide rail 202 drives the slider 203 to move in a ring. The slider 203 drives the fixed plate 204, hose 209, and nozzle 208 to move in a ring, thereby cooling different parts of the workpiece. When the angle of the nozzle 208 needs to be adjusted, the gooseneck tube 207 can be bent directly. The gooseneck tube 207 bends the hose 209 and supports the hose 209, thereby adjusting the angle of the nozzle 208. This solves the technical problem of traditional cooling mechanisms for CNC boring and milling machines, which use multiple gears for transmission. Due to the limited size of the U-shaped block, the cooling pipe only moves on the surface of the U-shaped block, and the range of movement of the cooling pipe is small. When different parts of the workpiece need to be cooled, the cooling effect on the workpiece is affected.

[0021] For details, see Figure 1 The cooling assembly includes an annular electric slide rail 202, a fixing plate 204, a water-air dual-purpose pump 205, a connecting pipe 206, a hose 209, a gooseneck pipe 207, and a nozzle 208.

[0022] Further, see Figure 1 The inner wall of the annular electric slide rail 202 is fixed with multiple connecting rods 201. One end of the slider 203 is slidably connected to the outside of the annular electric slide rail 202, and the other end of the slider 203 is fixed with a fixing plate 204.

[0023] It is worth noting that, see Figure 1 A water-air dual-purpose pump 205 is installed inside the fixed strip 204. A connecting pipe 206 is connected to the top of the water-air dual-purpose pump 205. One end of a hose 209 is connected to the bottom of the water-air dual-purpose pump 205. The other end of the hose 209 is connected to a nozzle 208. A gooseneck tube 207 passes through the outside of the hose 209, and one end of the gooseneck tube 207 is fixed to the bottom of the fixed strip 204.

[0024] It is worth noting that, see Figure 2 Both sides of the bottom of the base housing 1 are connected to miniature liquid pumps 303. The bottoms of the two miniature liquid pumps 303 are respectively connected to the top ends of the U-shaped flow cavity 304. When it is necessary to further improve the cooling effect, the two miniature liquid pumps 303 can be turned on. One miniature liquid pump 303 draws the coolant in the base housing 1 into the U-shaped flow cavity 304, and the other miniature liquid pump 303 draws the coolant in the U-shaped flow cavity 304 back into the base housing 1, so that the coolant circulates in the U-shaped flow cavity 304. Since a metal heat conduction plate 301 is provided on the top of the cutter head 302, the heat of the cutter head 302 can be conducted out by the metal heat conduction plate 301 and exchanged with the coolant flowing in the U-shaped flow cavity 304, thereby further cooling the cutter head 302. In conjunction with the cooling components, the cooling effect can be improved.

[0025] It is worth mentioning that, see Figure 1 The base box 1 has a liquid pipe 101 connected to one end of the liquid pipe 101 on both the upper and lower sides of the front end, and the other end of the liquid pipe 101 is detachably connected to a pipe cap 102.

[0026] When using a cooling mechanism for a CNC boring and milling machine, first connect the connecting pipe 206 to the external conveying pipe, then turn on the water-air dual-purpose pump 205. The water-air dual-purpose pump 205 draws external coolant into the hose 209, which is then sprayed onto the workpiece through the nozzle 208, thus cooling the workpiece. When it is necessary to remove debris from the workpiece surface, disconnect the conveying pipe from the surface of the connecting pipe 206, and directly use the water-air dual-purpose pump 205 to draw air, which is then sprayed onto the workpiece surface through the nozzle 208, thus removing debris. During the workpiece cooling process, when different positions of the workpiece need to be cooled, the annular electric slide rail 202 can be opened. The annular electric slide rail 202 will drive the slider 203 to move in a circular motion. The slider 203 will drive the fixed plate 204, hose 209, and nozzle 208 to move in a circular motion, thereby cooling different positions of the workpiece. When the angle of the nozzle 208 needs to be adjusted, the gooseneck tube 207 can be bent directly. The gooseneck tube 207 will bend the hose 209 and support the hose 209, thereby adjusting the angle of the nozzle 208. When the cooling effect needs to be further improved, two micro liquid pumps 303 can be turned on. One micro liquid pump 303 draws the coolant in the base box 1 into the U-shaped flow chamber 304, and the other micro liquid pump 303 draws the coolant in the U-shaped flow chamber 304 back into the base box 1, so that the coolant circulates in the U-shaped flow chamber 304. Since a metal heat conduction plate 301 is provided on the top of the cutter head 302, the heat of the cutter head 302 can be conducted out by the metal heat conduction plate 301 and exchanged with the coolant flowing in the U-shaped flow chamber 304, thereby further cooling the cutter head 302. In conjunction with the cooling components, the cooling effect can be improved.
