Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cooling liquid constant temperature device, specifically is a kind of grinding cooling liquid constant temperature device. BACKGROUND

[0002] Grinding machine is a kind of machining device to workpiece surface grinding process can process the workpiece surface of high smoothness, so it is often used as semi-finishing or finishing process.In grinding process, the high-speed movement of the outer edge of polishing wheel relative to the workpiece surface will generate high temperature, and often accompanied by sparks.If the heat generated during grinding process cannot be removed in time, the workpiece surface will be deformed by heat, and the plasticity will increase, which will seriously affect the workpiece surface finish and grinding accuracy.At present, the cooling liquid is usually poured on the contact part of polishing wheel and workpiece in the whole machining process to cool the workpiece in time and ensure the grinding quality.Because the cooling liquid is excessive, the worker usually does not stop the cooling liquid when operating, measuring and testing, and there is a large amount of cooling liquid on the workpiece surface and the grinding machine table, which causes the worker to contact the cooling liquid when operating.In winter, the cooling liquid temperature is low, and long-time operation can easily cause frostbite.

[0003] According to the published patent 201821881942.5, a grinding coolant constant temperature device, it includes a coolant recovery inlet, a coolant recovery outlet, a spiral tube, a liquid collection tube, a temperature sensor, a heater, and a temperature control circuit. The coolant recovery inlet and coolant recovery outlet are connected through the spiral tube, which is sleeved inside the liquid collection tube. The outer wall of the spiral tube abuts against the inner wall of the liquid collection tube. The outlet of the liquid collection tube is connected to the inlet of the grinding machine tool coolant pump. A heater is provided at the outlet of the liquid collection tube. A temperature sensor is provided between the heater and the inlet of the grinding machine tool coolant pump. Both the heater and the temperature sensor are connected to the temperature control circuit. The substantial effect of this utility model is that by detecting the temperature of the coolant entering the coolant pump inlet of the grinding machine tool using a temperature sensor, and controlling the start and stop of the heating device through a temperature control circuit, the coolant is kept within a suitable temperature range, preventing frostbite to workers. In the process of developing this utility model, the inventors discovered that at least the following problems remain unresolved in the prior art: Although the temperature sensor detects the temperature of the coolant entering the coolant pump inlet of the grinding machine tool, and the temperature control circuit controls the start and stop of the heating device to keep the coolant within a suitable temperature range and prevent frostbite to workers, in actual use, traditional grinding coolant temperature control devices use a heater to control the temperature of the grinding fluid. Since the heater only heats the grinding fluid from one location, the overall heating time of the grinding fluid is long, resulting in low heating efficiency. Moreover, since the temperature of the grinding fluid is controlled only by heating, when it is necessary to lower the temperature of the grinding fluid, the heater can only be turned off, and the temperature of the grinding fluid can be allowed to drop automatically, resulting in poor temperature control. Therefore, a new technical solution is needed to address these issues. Utility Model Content
