摘要： PURPOSE:To enable confirmation of the positions of a work and a roller, by providing an electrical circuit for lighting a lamp when two electrically conductive collars fixed to the opposite ends of the roller and rotatable together with the roller contact with the work. CONSTITUTION:Two springs 12 made of electrically conductive board are fixed through electrically insulating spacer 13 and a small screw 14 to a shaft end metal 9. When a collar 5 contacts with a work 1, an electrical circuit formed of the work 1, the collar 5, the leaf spring 12 and an electric wire 15 is brought into conducting condition so as to light a lamp connected in series with a power source in said circuit thus indicating contact between the collar 5 and the work 1. Two lamps are lighted simultaneously under the condition where two collars are contacting, so as to confirm that a proper angle is being set between the relative positions of the work and a teaching roller. Thereafter, the teaching roller is replaced by a polishing roller so as to transfer to automatic polishing work.

摘要： PURPOSE:To miniaturize an automatic centering device, by providing such an arrangement that a table is moved up and down by means of a horizontality adjusting receiving metal through a table fixing hardware, and is clamped by a clamping retaining metal through the table fixing hardware. CONSTITUTION:Under the control of a control board which is not shown, a worm shaft 27 and a worm wheel 28 are rotated, and a horizontality adjusting cylindrical screw shaft 33 moves by an instructed amount in an instructed direction. With this arrangement a workpiece attaching table is moved up and down by means of a horizontality adjusting metal 53 and a table fixing hardware 26 to adjust the horizontality and to center a workpiece. Then, a clamping jack device 15 is energized to move a clamping screw rod 20 in its clamping direction by means of an worm shaft 17 and a wheel 18, and a clamping retainer metal 24 is lowered to press the table fixing hardware 26 which therefore clamps the workpiece. With this arrangement, the centering may be rapidly and easily carried out, and as well it is possible to miniaturize the centering device.

摘要： PURPOSE:To enable an end face of blade groove to be bevelled with high accu racy by moving a column plate along the shape of blade groove with a copying pin copying a gauge plate so that a grinding wheel bevels the end face of blade groove to be worked. CONSTITUTION:A base plate 1 is fixedly located relative to a blade groove A to be worked with reference to a blade groove adjacent said groove A. And when an operator grasps a knob 16 to transfer two-dimensionally a copying pin 7 along the side surface of groove of a gauge plate 5, a column plate 2 draws the same locus as the blade groove. By driving an air motor 13 under such a condition is rotated a grinding wheel 19 which is mounted on the column plate 2 side to draw the same locus as the blade groove A under the gauge plate 5 guided condition and bevel the opposed corners B of blade groove A. Further, the bevelling shape can be freely selected by exchanging the grinding wheel 19 or adjusting the axial mounting position of grinding wheel.

摘要： PURPOSE:To permit the speedy centering by inputting the initial state of a work as the necessary conversion values of sensors into a controller and adjusting the horizontal degree and the right-angle degree on the basis of the initial state. CONSTITUTION:The initial state where a work is installed onto a work installation table 9, namely the intitial state obtained from the detected values by sensors 14-19, horizontal degree, and right-angle degree data are memorized into a control board 10. Centering is performed by adjusting the horizontal degree and the right-angle degree, comparing the memorized data with the sensing values of the sensors 14-19. With such constitution, the necessity of metering midway in the operation is obviated, and speedy centering is permitted.
