摘要： PROBLEM TO BE SOLVED: To provide a control device for a machine tool capable of properly holding a workpiece, even when holding force of a holding member is lowered. SOLUTION: In this machine tool, a chuck 8 is provided with a slide member 25 movably and drivably in a shaft center CT2 direction, and the workpiece 7 is fixed and held by using the chuck 8 by projecting a workpiece holding member 25g in the shaft center CT2 direction and moving the slide member 25 in the shaft center CT2 direction by driving a reciprocating and driving means 42. The machine tool is provided with a sensor 42d for detecting the release of the fixed and held state of the workpiece 7 by the workpiece holding member 25g during rotation of a main shaft 9, and driving and control means 46 and 50 for driving the slide member 25 in the shaft center CT2 direction (an arrow D direction) by the reciprocating and driving means 42 when detecting the release of the fixed and held state of the workpiece 7. Even when holding force such as hydraulic pressure of the workpiece holding member 25g is lowered, lowering of holding force of the workpiece 7 can be prevented to the utmost by moving the slide member 25 in the shaft center CT2 direction, that is, a workpiece direction.

摘要： PROBLEM TO BE SOLVED: To provide a method for lubricating a relatively moving mechanism of a power chuck capable of dispensing with regularly supplying or replacing reserve oil, and keeping a hollow chamber positive pressure to the atmosphere, and a power chuck having a movable mechanism for opening and closing a tongue. SOLUTION: A movable part of the chuck is stored in a sealed space having a circulation lubricating device. The circulation lubricating device is driven by force required for opening and closing the tongue of the chuck, especially a pressure difference between different parts of a hydraulic circuit for moving a jaw of the tongue.

摘要： PROBLEM TO BE SOLVED: To move a jaw portion in radial, axial and horizontal directions by methods independent of each other. SOLUTION: This chuck includes a plurality of jaw portions 8, each of them is fixed to the front end of a jaw portion holding arm 5, and the arm 5 is supported by a pivot joint 6 installed on a chuck main body 1. By the rotation of this pivot joint 6, substantially radial motion is provided to the jaw portion 8, the rotation being controlled by the radial displacement of a sliding element 4 for pushing a truncated conic ball 10, and the ball is housed between the sliding element 4 and a recessed portion formed in the arm 5 in the rear side of the pivot joint 6. The truncated conic ball 10 is slidable on a plane in contact with the sliding element 4, and thereby the jaw portion holding arm 5 is slid in the pivot joint 6 substantially in the axial direction while being pulled backward by a return spring 7.

摘要： PROBLEM TO BE SOLVED: To positively chuck a workpiece from two directions, miniaturize and lighten the chucking device, and improve the durability when the workpiece, etc., are chucked by four chucking jaws from two directions, namely from X axis direction and Y axis direction, in a machine tool. SOLUTION: Four sliders 12, 13 respectively provided with chucking jaws 20, 21 are provided in a chuck body 5 so that they can reciprocate and slide in four directions differed in phase by 90 deg.. Both the sliders 13 in X axis direction, out of the respective sliders 12, 13 are connected to an operating member 19 for X axis, arranged in the center so that they can be opened or closed simultaneously by the movement of the operating member 19, while both the sliders 12 in Y axis direction, out of the respective sliders 12, 13 are connected to an operating member 18 for Y axis, arranged in the center so that they can be simultaneously opened or closed by the movement of the operating member 18, and both the operating members 18, 19 are structured to be moved separately or simultaneously by a main piston 26 and an auxiliary piston 33 respectively.

摘要： PROBLEM TO BE SOLVED: To directly measure the force for moving a clamp jaw of a drill chuck by mounting a stress sensor in a stress transmission link comprising a ram shaft, a clamping rod and a chuck ram. SOLUTION: A clamping ram 2 is connected integrally to a ram shaft 5, and the ram shaft 5 is connected to a clamping rod 6. By the movement of the clamping ram 2, the tensile force and the pressure force are transmitted to the clamping rod 6, and the magnitude of this stress can be measured by a stress sensor 16 mounted on the connection part of the ram shaft 5 and the clamping rod 6. Further as the other arrangement of the stress sensor, it can be also mounted between the clamping rod 6 and the chuck ram. The movement in the axial direction of the clamping ram 2 is transmitted to the chuck ram through the clamping rod 6, and the clamp jaw of the drill, chuck is moved in the radial direction through a bell crank to be engaged with a groove of the chuck ram. The movement force can be directly measured by this stress sensor 16.
