Abstract: A temperature regulation system and a temperature regulation method are applicable to a machine tool. The temperature regulation system includes a cooling fluid storage tank, a heating fluid storage tank, an internal circulation subsystem, an external circulation subsystem and a computing unit. The internal circulation subsystem includes a first valve. The external circulation subsystem includes a plurality of flow channels and a second valve and a third valve disposed on the plurality of the flow channels. The computing unit controls the first valve, the second valve and the third valve to switch flow directions of the plurality of the flow channels among the cooling fluid storage tank, the heating fluid storage tank and machine tool. Therefore, a thermal balance of the machine tool can be effectively maintained.

Abstract: A machining thermostatic control system and method of using the same are disclosed. The system comprises a detecting unit, a processing unit and at least a cooling unit. The detecting unit is used for detecting the temperature distribution of a workpiece. The processing unit is coupled to the detecting unit and is used for processing the temperature distribution for obtaining a position of maximum hot spot of the workpiece. The cooling unit comprises a head which is provided for discharging cooling fluid and a plurality of blades which are angle-adjustably mounted to the head. The blades are coupled to the processing unit and the angle of blades are controlled by the processing unit for enabling the cooling fluid to flow toward to the position of maximum hot spot position.

Abstract: The disclosure is a thermal stability control system and a control method thereof for a machine tool. The control system mainly consists of a machine cooling sub-system composed of a pump, at least a cooling loop and a tank for storing cooling fluid, a cooling fluid cooling and heating sub-system, a heater and a micro controller. The cooling fluid cooling and heating sub-system further consists of a condenser, an evaporator, a directional valve, an expansion valve and a compressor. The micro controller dominates corresponding operation combinations of turning on/off the heater, enabling/disenabling the cooling fluid cooling and heating sub-system as a heat pump or a cooler by activating/releasing the directional vale, and adjusting upward/downward the driving frequency of an inverter duty motor to drive the pump to change the flow rate of cooling fluid through the cooling loop according the real time load of the machine tool.

Abstract: This disclosure relates to a temperature control system that may be applied to a machine tool. The system includes a cooling circulation and a controller. The cooling circulation comprises a pump, a cooler and a solenoid valve. The pump may be driven by a variable frequency motor so as to flow through the spindle of the machine tool. The cooler is serially connected with the liquid pump, and may cool the liquid coolant. The solenoid valve connects to inlet and outlet of the cooler, and may prevent the liquid coolant flows through the spindle from flowing back to the cooler. The controller is electrically connected with the variable frequency motor, the cooler and the solenoid valve. Further, the controller is connected to the machine tool to detect several parameters, so as to control the variable frequency motor, the cooler and the solenoid valve.

Abstract: A clamping and positioning device includes a base, a rotary member, a moving assembly and an elastic member. The rotary member is rotatably disposed on the base and includes a stopping surface facing the base. The moving assembly includes a moving member movably disposed on the base to have a first and a second position. When being at the first position, the moving member is pressed against the rotary member to allow the stopping surface to apply a normal force to the base; when being at the second position, a gap is formed between the moving member and the rotary member so the normal force applied by the stopping surface of the rotary member is released from the base. The elastic member has two ends connected to the base and the moving member, respectively. The elastic member normally causes the moving member to be at the first position.
