摘要： PURPOSE: To simplify slide table machining work and miniaturize and lighten the whole of a linear actuator by reducing the width of a actuator body in its cross direction without deteriorating the linearity accuracy of the slide table. CONSTITUTION: A linear actuator 10 is provided with a cylinder body 12 in which an opening 26a is formed, a slide table 14, a joint member 24, which is jointed at the bottom face section of the slid table 14 in nearly orthogonal relationship, and a pair of pistons 42a and 42b, which are slidably arranged along the cylinder chamber demarcated in a through hole 32 and press the joint member 24 with pressure fluid supplied. In addition, it is provided with a guide section 56 expandedly formed oh the bottom face section of the slide table 14, a pair of guide blocks expandedly formed in the top face of the cylinder body 12 and a plurality of ball bearings interposed between the guide section 56 and the guide blocks.

摘要： PURPOSE: To obtain a small working device using a small cylinder by disposing a rhombic cross sectional guide below a mold conveyor, providing a roller box engaged with a holding roller movably and fitting a rotatatably/vertically movable working mechanism. CONSTITUTION: At the time of moving a sand mold 3 on the mold conveyor 2, a sprue cutter 22 rotated by a motor 7 is ascended with an elevating cylinder 19 and a sprue 3A communicated with the runner 3B is cut off. In the case of transferring the sand mold 3 being different position of the sprue 3A, the sprue cutter 22 is cut off so as to be accurately matched with the sprue 3A by working a first cylinder 8 and a second cylinder 11. The cylindrical roller box 7 is guided by a fixed guide 4 and a moving guide 13 is guided to a cylindrical roller box 15 and moved in the linear state. The first cylinder 8 and the second cylinder 10 can be satisfied with the small type capable of moving only the working mechanism, and the device can be made small in size.

摘要： PURPOSE:To enable a spindle to accurately fine move by changing a pnenumatic pressure acting in a thrust surface of the spindle, making the spindle take refuge, and resetting the spindle to the original point by the same pressure. CONSTITUTION:When moved to a measuring position after the first time grinding, ordinarily in the case of moving a grinding wheel to escape by linear moving, about 6kgwt./cm air pressure is left as supplied to a bearing clearance 13 from a port 9, to supply air pressure lower than about 6kgwt./cm to a bearing clearance 14 from a port 10. In this way, a spindle 3 is retracted about 3 to 5mum in accordance with a difference of air pressure between both the bearing clearances 13, 14. After retracted, a supply pressure of the port 10 is again increased, and by equalizing to the pressure of the port 9, the spindle 3 is reset to the moving original point.

摘要： PURPOSE:To permit the small output of a driving motor for turning a tilt table and smoothly carry out the positioning and work for a workpiece with high precision. CONSTITUTION:A controller for tilt table is equipped with a tilt table 5 on which a workpiece is placed and which is supported in a turnable manner on supporting boards 3 and 4, servomotor 19 for tilting the tilt table 5 around the turning shaft, and a cylinder device 21 for balance which applies the torque in the direction offsetting the imbalance moment during the tilt of the tilt table 5 to the tilt table 5. The imbalance moment of the tilt table 5 is calculated according to the balance calculation program on the basis of the turning angle detected by an encoder 28 during the operation of the tilt table 5, and the fluid pressure supplied to the cylinder device 21 for balance from a fluid pressure pump 27 is controlled according to the turning angle by controlling an electromagnetic reducing valve 26 so that the imbalance moment is offset.
