摘要： PROBLEM TO BE SOLVED: To compensate positional deviation of a drive table based on pitch error of a two-spindle machine tool device driving one drive table by motors for two spindles and ball screws.
SOLUTION: A synchronous controller as a command switch means for transmitting a command sent from a high-order device to the motor of the spindle selected arbitrarily from among the first spindle and the second spindle, two attitude detection means for detecting the attitude of the drive table, and a pitch error compensation memory for storing a compensation value for a pitch error. When the drive table has a predetermined attitude at a first position, the drive table is moved in the direction of the second attitude detection means by a predetermined distance corresponding to a predetermined command value, and a command is given to either or both of the motors of the first spindle and the second spindle at the position to compensate eccentricity of a position and eccentricity of an attitude of the drive table. At this time, the compensation for the pitch error of the ball screws of the first spindle and the second spindle is performed based on the command value given to the motors of the first spindle and the second spindle.

摘要： PROBLEM TO BE SOLVED: To reduce the weight of an X table to reduce the inertia force of the X table by arranging a drive motor for the Y axis on the bed on which the X table is provided and transmitting the drive force of the drive motor for Y axis to the ball screw for driving a Y table through a ball spline shaft and a bevel gear. SOLUTION: An X table 2 is arranged so as to reciprocate on orbital rails through a slider 13 in the X direction. A plurality of track rails, i.e., orbital rails 8, are fixed to the X table 2 by bolts, etc., in parallel with each other. A slider 7 is fixed to the lower face of a Y table 1. The slider 7 is mounted on the orbital rails r so as to slidably move. Therefore, the Y table 1 reciprocate through the slider 7 in the Y axis direction orthogonal to the X axis direction. Positioning is made by moving the equipment attached on this Y table 1 to a specified position on a flat plane.

摘要： PURPOSE: To obtain a floating mechanism which possesses the high rigidity in the axial direction of a feeding screw and generates the little dangling. CONSTITUTION: A floating member 18 is constituted of the first floating member 18a which is swingable in the X direction and the second floating member 18b which is swingable in the Y direction, by forming the hinge springs 21 and 22 in the flexible direction which cross at right angle on the same plane by cutting a plate-shaped work in the plate thickness direction, and both the floating parts are fixed on a table or a bed, directing the plate thickness direction in the same direction to the axis line of a feeding screw, and a bearing for a nut or the feeding screw is fixed on the second floating part 18b.

摘要： PURPOSE:To provide a device excellent in operability in the case of the delivery device of a grinder equipped with the two drive systems of motor drive and manual drive. CONSTITUTION:Friction plates 66a, 66b, plates 58a, 58b and a friction clutch 80 having predetermined frictional force that is by means of a friction giving means 65, are formed between an ascent/descent motor 50 and a delivery screw 42. The frictional force is set larger than resistance at the time of the delivery screw 42 being driven, and smaller than resistance at the time of the ascent/ descent motor 50 being made to rotate. As a result, in a case in which the delivery screw 42 is driven by means of the ascent/descent motor 50 automatically without conducting the operation of the friction clutch 80, the friction clutch 80 is connected, and in a case in which the delivery screw 42 is operated manually, the friction clutch 80 is slid, and operation can be accomplished by means of small force.

摘要： PURPOSE:To speed up positioning without increasing torque required for driving a feed screw in the table device employing the feed screw. CONSTITUTION:A sliding unit 4 is provided for the shaft end section of a feed screw 1 in such a way as to be slidably rotated with respect to the feed screw 1, and the sliding unit 4 is connected to a viscosity attenuation element 5 provided for a fixed section 3. The viscosity attenuation element 5 retains rotational vibration when the feed screw 1 is positioned. When excessive torque beyond requirement is applied to the viscosity attenuation element 5, the sliding unit 4 is slidably rotated with respect to the feed screw.
