Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting tool cooling technology, and in particular to a cutting tool cooling device. Background Technology
[0002] The core function of tool cooling is to effectively reduce the temperature of the cutting area (usually through coolant spraying, gas purging, or internal circulation), thereby suppressing frictional heat that causes premature wear, softening, and deformation of the tool edge, thus significantly extending tool life; at the same time, it reduces workpiece thermal deformation and surface damage, ensuring machining accuracy and surface finish; by maintaining stable tool cutting performance, it supports higher cutting parameters to improve efficiency; it assists in chip removal in the cutting zone, avoiding chip adhesion and secondary cutting; and it reduces the risk of high-temperature chip splashing and cutting fluid evaporation pollution, balancing machining safety and environmental protection.
[0003] A search revealed a patent document with publication number CN221560658U disclosing a lubrication and cooling device for alloy milling cutters. The device includes a housing, a water tank on one side of the upper part of the housing, an oil tank on the side of the upper part of the housing away from the water tank, a drive motor located at the center of the upper part of the housing on one side of the oil tank, a mounting plate connected to the output end of the drive motor, a magnetic suction plate connected to the bottom of the mounting plate, a cutting tool connected to the bottom of the magnetic suction plate, a cleaning roller below the cutting tool, and a water collection plate on one side of the cutting tool. This invention utilizes an infrared thermometer to detect the temperature of the cutting tool during cooling, allowing for real-time monitoring of the tool's cooling temperature. This enables the tool to be removed and used promptly when cooled to a suitable temperature, improving work efficiency. The cleaning roller can move upwards to the outside of the cutting tool; as the tool rotates within the cleaning roller, residual iron filings are scraped off, allowing lubricating oil to be evenly sprayed onto the tool surface.
[0004] Regarding the aforementioned related technologies, the inventor believes that the following defects exist:
[0005] 1. The above device is not convenient for adjusting the height of the spray nozzle during use. In specific applications, different processing techniques use different specifications of cutting tools, resulting in different tool lengths. Therefore, the above device may not be able to meet the cooling requirements of various different specifications of cutting tools.
[0006] 2. The spray nozzle of the above device is parallel to the horizontal plane, which may cause the coolant to be sprayed directly onto the non-working part of the tool (such as the shank of the drill bit or the shank of the end mill), and only a small amount of coolant may act on the tool tip. Therefore, it is easy to waste coolant and may also affect the cooling effect on the tool tip. Utility Model Content
[0007] To address the technical problems of the aforementioned device, such as the inconvenience in adjusting the height of the spray nozzle and the fact that the angle of the spray nozzle is parallel to the horizontal plane, this utility model provides a blade cooling device.
[0008] This utility model is achieved using the following technical solution: A main structure comprising a mounting plate, a cutting device, a limiting rod, and a lead screw, with two sets of limiting rods; a cooling structure comprising a cooling ring, a nozzle, and a limiting plate, with multiple sets of nozzles and two sets of limiting plates, each set of limiting plates being sleeved on the outer surface of two sets of limiting rods; a fixing plate fixedly connected to the outer surface of one side of the mounting plate, and a cooling water tank fixedly connected to the upper surface of the fixing plate; the cutting device being installed at the middle position of the lower surface of the fixing plate.
[0009] With the above technical solution, the mounting plate can be fixed to the machine tool during use, thereby fixing the overall position of the device. Coolant can be injected into the cooling water tank during use.
[0010] As a further improvement to the above solution, limit rods are fixedly connected to both sides of the lower surface of the fixed plate, and limit rings are fixedly connected to the lower ends of the two sets of limit rods, and the diameter of the two sets of limit rings is larger than the diameter of the two sets of limit rods.
[0011] Through the above technical solution, the two sets of limiting plates can move longitudinally on the outer surfaces of the two sets of limiting rods respectively. Since the diameter of the two sets of limiting rings is larger than the diameter of the two sets of limiting rods, the two sets of limiting plates can be prevented from detaching from the outer surfaces of the two sets of limiting rods during movement, thus effectively improving the stability of the two sets of limiting plates during movement.
[0012] As a further improvement to the above solution, a drive motor is installed at one end of the lower surface of the fixed plate, and a lead screw is fixedly connected to the output end of the drive motor.
[0013] With the above technical solution, when in use, the drive motor can be powered by an external power source. After the drive motor starts, its internal output terminal will drive the lead screw to rotate.
[0014] As a further improvement to the above solution, a connecting pipe is connected to the interior of the outer surface of one end of the cooling ring, and one end of the connecting pipe is connected to the interior of the cooling water tank.
[0015] The above technical solution includes a liquid pump installed inside the cooling water tank, which is connected to one end of a connecting pipe. After the liquid pump is started, the coolant inside the cooling water tank can be transported to the inside of the cooling ring through the connecting pipe.
[0016] As a further improvement to the above solution, all of the multiple sets of nozzles are fixedly connected to the inside of the cooling ring, and the inside of the cooling ring is connected to the inside of the multiple sets of nozzles. The multiple sets of nozzles are arranged in a ring shape, and one end of the multiple sets of nozzles has a downward angle of ° relative to the horizontal plane.
[0017] With the above technical solution, the coolant inside the cooling ring will be sprayed outward through multiple sets of nozzles. One end of each set of nozzles has a 45° downward angle relative to the horizontal plane. Therefore, one end of each set of nozzles will tilt towards the cutting head of the cutting device, forming a diving angle. This makes it easier for the focus of the sprayed coolant to fall on the cutting head with the highest temperature. Furthermore, the diving coolant can more effectively flush the cutting area, which helps to carry the chips out along the chip removal groove of the tool or blow them away from the workpiece surface.
[0018] As a further improvement to the above solution, the two sets of limiting plates are respectively fixedly connected to the outer surfaces of both sides of the cooling ring, and a connecting plate is fixedly connected to the outer surface of the other end of the cooling ring. The lead screw is threadedly connected to the interior of one end of the connecting plate.
[0019] The above technical solution enables the lead screw to mesh with the limit rod during rotation, which in turn drives the connecting plate to move longitudinally. This, in turn, drives the entire cooling structure to move longitudinally, allowing the overall height of the cooling structure to be adjusted to match the specific length of the cutting tool.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] This utility model can drive the lead screw to rotate by starting the drive motor. When the lead screw rotates, it can mesh with the limiting rod, which can drive the connecting plate to move longitudinally, thereby driving the entire cooling structure to move longitudinally. Furthermore, the setting of two sets of limiting rods and limiting plates can improve the stability of the entire cooling structure during movement. This design allows the height of the entire cooling structure to be adjusted according to the specific length of the tool, thereby improving the applicability of the device to a certain extent.
[0022] Furthermore, the present invention uses multiple sets of nozzles to ensure that the sprayed coolant can cover the circumference of the cutting head more evenly. By setting the multiple sets of nozzles at a 45° downward angle, the focus of the sprayed coolant can more easily fall on the cutting head with the highest temperature. The downward-flowing coolant can more effectively flush the cutting area and help to carry the chips out along the chip removal groove of the tool or blow them away from the workpiece surface. This design can effectively improve the cooling effect of the device on the cutting head. Attached Figure Description

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0030] Please combine Figures 1-4 The cutting head cooling device of this embodiment includes: a cutting head cooling device, including: a main structure 1, the main structure 1 including a mounting plate 11, a cutting device 14, a limiting rod 15 and a lead screw 18, and the limiting rod 15 is provided in two sets; a cooling structure 2, the cooling structure 2 including a cooling ring 21, a nozzle 23 and a limiting plate 24, the nozzle 23 is provided in multiple sets, the limiting plate 24 is provided in two sets, and the two sets of limiting plates 24 are respectively sleeved on the outer surface of the two sets of limiting rods 15. A fixing plate 12 is fixedly connected to the outer surface of one side of the mounting plate 11, and a cooling water tank 13 is fixedly connected to the upper surface of the fixing plate 12. The cutting device 14 is installed at the middle position of the lower surface of the fixing plate 12.
[0031] With the above technical solution, the mounting plate 11 can be fixed to the machine tool during use, thereby fixing the position of the entire device. Coolant can be injected into the cooling water tank 13 during use.
[0032] As a further improvement to the above solution, both sides of the lower surface of the fixing plate 12 are fixedly connected to limit rods 15, and the lower ends of the two sets of limit rods 15 are fixedly connected to limit rings 16, and the diameter of the two sets of limit rings 16 is larger than the diameter of the two sets of limit rods 15.
[0033] Through the above technical solution, the two sets of limiting plates 24 can move longitudinally on the outer surfaces of the two sets of limiting rods 15 respectively. Since the diameter of the two sets of limiting rings 16 is larger than the diameter of the two sets of limiting rods 15, the two sets of limiting plates 24 can be prevented from detaching from the outer surfaces of the two sets of limiting rods 15 during movement, thus effectively improving the stability of the two sets of limiting plates 24 during movement.
[0034] As a further improvement to the above solution, a drive motor 17 is installed at one end of the lower surface of the fixed plate 12, and a lead screw 18 is fixedly connected to the output end of the drive motor 17.
[0035] With the above technical solution, when in use, the drive motor 17 can be powered by an external power source. After the drive motor 17 is started, its internal output terminal will drive the lead screw 18 to rotate.
[0036] As a further improvement to the above scheme, a connecting pipe 22 is connected to the interior of the outer surface of one end of the cooling ring 21, and one end of the connecting pipe 22 is connected to the interior of the cooling water tank 13.
[0037] With the above technical solution, the cooling water tank 13 is equipped with a liquid pump and is connected to one end of the connecting pipe 22. After the liquid pump is started, the coolant inside the cooling water tank 13 can be transported to the interior of the cooling ring 21 through the connecting pipe 22.
[0038] As a further improvement to the above scheme, multiple sets of nozzles 23 are all fixedly connected to the inside of the cooling ring 21, and the inside of the cooling ring 21 is connected to the inside of the multiple sets of nozzles 23. The multiple sets of nozzles 23 are arranged in a ring shape, and one end of the multiple sets of nozzles 23 has a 45° downward angle relative to the horizontal plane.
[0039] Through the above technical solution, the coolant inside the cooling ring 21 will be sprayed outward through multiple sets of nozzles 23. One end of the multiple sets of nozzles 23 has a 45° downward angle relative to the horizontal plane. Therefore, one end of the multiple sets of nozzles 23 will be tilted towards the cutting head of the cutting device 14, forming a downward angle, which makes it easier for the focus of the sprayed coolant to fall on the cutting head with the highest temperature. Furthermore, the downward-sweeping coolant can more effectively flush the cutting area, which helps to carry the chips out along the chip removal groove of the tool or blow them away from the workpiece surface.
[0040] As a further improvement to the above scheme, two sets of limiting plates 24 are fixedly connected to the outer surfaces of both sides of the cooling ring 21, and a connecting plate 25 is fixedly connected to the outer surface of the other end of the cooling ring 21. The lead screw 18 is threadedly connected to the interior of one end of the connecting plate 25.
[0041] Through the above technical solution, the lead screw 18 can mesh with the limit rod 15 when rotating, which can drive the connecting plate 25 to move longitudinally, thereby driving the cooling structure 2 as a whole to move longitudinally, so that the height of the cooling structure 2 as a whole can be adjusted to a certain extent according to the specific length of the tool.
[0042] The implementation principle of a blade cooling device in this application embodiment is as follows:
[0043] Step 1: First, start the drive motor 17 to drive the lead screw 18 to rotate. Then, when the lead screw 18 rotates, it will drive the connecting plate 25 to move longitudinally, thereby driving the cooling structure 2 to move longitudinally as a whole. At this time, the height of the cooling structure 2 can be adjusted according to the length of the tool on the cutting device 14.
[0044] Step 2: Then, during the cutting process of the cutting device 14, the liquid pump inside the cooling water tank 13 is started first. Then, the liquid pump will transport the coolant inside the cooling water tank 13 to the inside of the cooling ring 21 through the connecting pipe 22, and then spray it onto the cutting head of the cutting device 14 through multiple sets of nozzles 23. At this time, the cutting head of the cutting device 14 can be cooled.
[0045] The cutting device 14, drive motor 17 and liquid pump used in this application are all products that can be purchased directly on the market. The model of drive motor 17 is SGM7J-1AFC6S. Its principle, connection method and control method are all existing technologies known to those skilled in the art, so they will not be described in detail here.
[0046] The cutting device 14, drive motor 17, lead screw 18, multiple sets of nozzles 23, and all movable parts in this application require regular cleaning and maintenance (including but not limited to dust removal and lubrication) to ensure their normal operation.
[0047] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
