    • PURPOSE: A standard point establishment method of a tool position is provided to minimize a machine work and accurately distinguish the tool position by conveniently and accurately establishing a longitudinal direction center line of a tool for the machine work with a standard point of the tool position. CONSTITUTION: A standard point establishment method of a tool position comprises as follows. A laser beam is irradiated from a laser with a light detector according to a predetermined direction (S10). A tool desiring the establishment of a standard point between the laser and the light detector is moved at a fixed distance as a fixed interval according to the direction which is at right angles to an irradiated direction of the laser beam (S20). When the tool is overlapped with the laser beam by moving between the laser and the light detector, the strength of the laser beam is measured by receiving the laser beam irradiated in a laser beam irradiating step (S40). The strength of the laser beam measured in a laser beam strength measuring step is converted into the intensity of an output voltage (S50). A point in which the intensity of the changed output voltage converted in an output voltage converting step is minimally set up as the standard point of a tool moving direction axle (S60). [Reference numerals] (S10) Step of irradiating a laser beam; (S20) Step of moving a tool at a fixed distance; (S30) Step of measuring the location of the tool; (S40) Step of measuring the strength of the laser beam; (S50) Step of converting an output voltage; (S60) Step of setting a reference point; (S70) Step of correcting an original point of the tool

    • The present invention relates to a volume adjustable piston for internal combustion including: a cylinder body constantly moving up and down inside a cylinder and vertically forming a pair of grooves facing each other; a pin in which two ends are inserted into each of the grooves to be slid, combined to a connecting rod; and an elastic member in which longitudinal one end is arranged at the top of the pin while being arranged inside the body and longitudinal other end is hooked at the top of the inner surface of the body to make the body elastically supported on the pin. Elastic modulus of the elastic member is designed to correspond to the maximum inner pressure of the cylinder. Therefore, after the internal pressure of the cylinder reaches the designed maximum pressure, the elastic member is pressured proportionally to an increase of internal pressure inside a combustor, and the volume of the combustor increases to maintain the combustor at a certain level of internal pressure. If the internal pressure of the combustor becomes lower than the elastic modulus of the elastic member, the body elevates by the expansion of the elastic member to return the volume of the combustor to its original state. Certain amount of energy by the internal pressure of the cylinder is stored as potential energy as the elastic member is pressed and diffuses the potential energy as the elastic member is expanded. The total amount of energy is not changed, only the volume of maximum inner pressure of the cylinder is reduced, so that the friction between the cylinder and the body can be reduced.
    • 本发明涉及一种用于内燃的容积可调节活塞,包括:缸体,其在气缸内不断地上下移动,并垂直地形成一对面对的槽; 一个销,其中两端插入每个要滑动的槽中,组合到一个连杆上; 以及弹性构件,其中纵向一端布置在销的顶部,同时布置在主体内部,并且纵向另一端钩在主体的内表面的顶部,以使得主体弹性地支撑在销上。 弹性构件的弹性模量被设计成对应于气缸的最大内部压力。 因此,在气缸的内压达到设计的最大压力之后,弹性部件与燃烧器内部的内部压力的增加成比例地加压,并且燃烧器的体积增加,以将燃烧器维持在一定的内部压力水平。 如果燃烧器的内部压力低于弹性部件的弹性模量,则通过弹性部件的膨胀使本体升高,使燃烧器的体积恢复到原来的状态。 通过气缸的内部压力将一定量的能量作为势能被储存为弹性构件被按压时的能量,并且随着弹性构件的膨胀而扩散势能。 总能量没有变化,只有气缸的最大内压体积减小,从而可以减小气缸与机体之间的摩擦。
