    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: 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.

    Abstract translation: 夹持定位装置包括底座,旋转构件,移动组件和弹性构件。 旋转构件可旋转地设置在基座上并且包括面向基座的止动表面。 移动组件包括可移动地设置在基座上以具有第一和第二位置的移动构件。 当处于第一位置时,移动构件被压靠在旋转构件上,以允许止动面向基座施加法向力; 当处于第二位置时,在移动构件和旋转构件之间形成间隙,因此由旋转构件的止动面施加的法向力从基座释放。 弹性构件具有分别连接到基座和移动构件的两端。 弹性构件通常使移动构件处于第一位置。
