Description

Technical Field

[0001] This utility model relates to a machine tool cooling device, specifically a temperature balancing device for a machine tool cooling system. Background Technology

[0002] During machine tool machining, the cutting of the workpiece generates heat, which affects the position of the tool tip and thus alters machining accuracy. Therefore, a machine tool cooling system is needed to control machining accuracy. Common machine tool cooling systems use an external spindle flushing pump to spray cutting fluid, flushing and cooling the tool tip. However, because the cutting fluid is stored and transported under ambient temperature conditions, it is significantly affected by the ambient temperature. When the ambient temperature is high or low, or fluctuates greatly, the cutting fluid's cooling effect on the tool tip is poor, or even has adverse effects.

[0003] Therefore, the following difficulties exist in the existing cutting fluid cooling system: 1. The cutting fluid temperature cannot be set; 2. The cutting fluid temperature cannot be kept constant despite the influence of ambient temperature. Summary of the Invention

[0004] To solve the above problems, this invention designs a temperature balancing device for a machine tool cooling system. By adding a cooling machine in conjunction with a temperature sensor, the temperature of the cutting fluid is controlled. Furthermore, an oil-cooled or water-cooled machine with high control accuracy and fast response speed is selected to free the temperature of the cutting fluid from the influence of the ambient temperature, thereby achieving a constant temperature.

[0005] To solve the above-mentioned technical problems, this utility model provides a temperature balancing device for a machine tool cooling system, characterized in that it includes a water tank, a diaphragm water pump, a cooler, and an electrical control box. The cooler and the water tank are placed side by side. The diaphragm water pump and the electrical control box are fixed on top of the water tank. The water tank is connected to an external spindle flushing pump through the diaphragm water pump and a delivery pipe. Both the diaphragm water pump and the external spindle flushing pump are electrically connected to the electrical control box and controlled by it. A machine tool cutting fluid return pipe is also connected to the water tank. An outlet pipe and an inlet pipe are provided between the cooler and the water tank. The cutting fluid circulates between the water tank and the cooler along the outlet pipe and the inlet pipe. The cooler is electrically connected to the electrical control box and controls the cooling temperature. A first temperature sensor for detecting the cutting fluid temperature is also installed inside the water tank and is electrically connected to the electrical control box.

[0006] Furthermore, a second temperature sensor is installed inside the water tank to detect the temperature of the cutting fluid after it has been cooled by the cooler. The second temperature sensor is located inside the water tank and directly opposite the connection between the inlet pipe and the water tank. The second temperature sensor is electrically connected to the electrical control box.

[0007] Furthermore, the water tank is also equipped with a third temperature sensor for detecting the temperature of the cutting fluid outlet at the machine tool end. The third temperature sensor is located at the upper end of the water tank and is directly opposite the connection between the machine tool cutting fluid return pipe and the water tank. The third temperature sensor is also electrically connected to the electrical control box.

[0008] Furthermore, the cooling machine is an oil-cooled or water-cooled machine, and a fan assembly for heat dissipation is installed on the top of the cooling machine.

[0009] After adopting the above structure, the present invention has the following beneficial effects:

[0010] 1. This utility model controls the temperature of the cutting fluid by adding a cooling machine in conjunction with a temperature sensor, and selects an oil-cooled or water-cooled machine with high control accuracy and fast response speed, so that the temperature of the cutting fluid is freed from the influence of the ambient temperature, thereby achieving constant temperature.

[0011] 2. In this utility model, the temperature of the cutting fluid can be set by an oil-cooled or water-cooled machine, thereby better removing the heat generated by the cutting tip cutting the workpiece, ensuring machining accuracy, and increasing practical performance.
