Description

Technical Field

[0001] The utility model relates to the technical field of water cooling of machine tools, in particular to a water cooling heat dissipation mechanism for machine tools. Background Art

[0002] In the metal processing and manufacturing industries, drilling machines are mainly used to drill holes in workpieces. That is, while the drill bit rotates at high speed, a certain feed force is applied to cause relative movement between the drill bit edge and the workpiece material, thereby gradually cutting out the desired hole. However, during the drilling process, the energy generated by the friction between the drill bit and the workpiece material and the cutting deformation will be converted into heat energy and accumulated in the contact area between the drill bit and the workpiece. This heat accumulation will not only lead to the degradation of the drill bit material performance, but also accelerate the wear of the drill bit and even cause the drill bit to break. Therefore, during use, a water spray pipe aimed at the drill bit is usually installed on the drilling machine tool to spray low-temperature cold water directly onto the working drill bit. This can remove the high-temperature heat on the drill bit surface and the surrounding area, reducing material deformation and cutting resistance caused by high temperature.

[0003] During machine tool drilling operations, the existing water spray pipe system is primarily designed to directly cool the drill bit. As the core component driving the drill bit, the motor also generates heat accumulation during continuous operation. If this heat cannot be dissipated promptly and effectively, it will directly affect the motor's operating efficiency and service life. The existing water spray pipe system only focuses on dissipating heat from the drill bit and fails to extend the cooling effect to the motor part, resulting in insufficient heat dissipation efficiency.

[0004] In order to solve the above problems, this application proposes a water-cooling heat dissipation mechanism for a machine tool. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes a water-cooling heat dissipation mechanism for a machine tool.

[0006] The utility model provides a water-cooling heat dissipation mechanism for a machine tool, comprising a base and a water cooling box installed on the base;

[0007] A drilling machine is installed on the base, and a water cooling box is located on one side of the drilling machine. A drill bit and a motor for driving the drill bit to rotate are installed on the drilling machine.

[0008] An overflow bellows is installed on the top of the water cooling box. A cavity is formed in the overflow bellows. A separation plate is installed in the cavity. The separation plate divides the cavity into an overflow chamber and a blowing chamber. A disturbance blowing member is rotatably connected to the separation plate and is respectively placed in the overflow chamber and the blowing chamber.

[0009] The drilling machine tool is provided with a water cooling element arranged toward the drill bit and communicating with the flow chamber in the flow bellows;

[0010] A water supply component for conveying water into the flow chamber is installed at the bottom of the water cooling box;

[0011] The top of the overflow air box is connected with an air duct communicated with the blowing chamber, and the air duct is used to guide the cold air into the motor.

[0012] Preferably, the disturbance blowing member includes a shaft, a through opening is provided in the middle of the separation plate, the shaft rotates vertically through the opening, the two ends of the shaft are respectively rotatably connected to the top and bottom of the flow bellows, the shaft is mounted with paddles located in the flow chamber and axial flow blades in the blowing chamber, and the outer periphery of the flow bellows is provided with an air inlet hole connected to the blowing chamber.

[0013] Preferably, the water-cooling component includes a water spray pipe, which is installed at an angle on the drilling machine and arranged toward the drill bit. The bottom end of the water spray pipe is provided with a water spray hole arranged toward the drill bit. The top end of the water spray pipe is connected to a guide pipe, and the end of the guide pipe away from the water spray pipe passes through the side of the flow box and is connected to the flow chamber.

[0014] Preferably, the water supply component includes a water pump, which is installed at the bottom of the water cooling box and connected to its interior. The water outlet of the water pump is connected to a water supply pipe, and the end of the water supply pipe away from the water pump is connected to the side of the flow box away from the guide pipe, and the water supply pipe is connected to the flow chamber.

[0015] Preferably, a heat dissipation port is provided on the top of the motor, and one end of the air duct away from the flow bellows is connected to the outer periphery of the motor, and the air duct is in communication with the heat dissipation port.

[0016] The above technical solution of the utility model has the following beneficial technical effects:

[0017] By setting the disturbance blowing parts, water cooling parts, water supply parts and air ducts, the cold water in the water cooling box can be guided to the flow chamber in the flow box through the water supply parts, and then sprayed to the drill bit through the water cooling parts, thereby playing a role in cooling the drill bit during workpiece processing. When the water flows through the flow chamber, it will drive the disturbance blowing parts to rotate. When the disturbance blowing parts rotate, they will generate cold air in the blowing chamber and guide it into the motor along the air duct to blow air into the motor, accelerating the dissipation of heat in the motor. This structure realizes the simultaneous heat dissipation of the motor and the drill bit during the drilling operation of the drilling machine, thereby ensuring the operating stability of the motor and extending the service life, while also having a direct cooling effect on the drill bit, and comprehensively improving the overall performance of the drilling operation of the drilling machine.

The bottom end of the water spray pipe 91 defines a water spray hole facing the drill bit 5. The top end of the water spray pipe 91 is connected to a flow guide pipe 92. The end of the flow guide pipe 92, away from the water spray pipe 91, passes through the side of the flow bellows 6 and communicates with the flow chamber.

[0026] In this embodiment, a water supply component 10 for directing water into the overflow chamber is installed at the bottom of the water-cooling box 2.
