摘要： PROBLEM TO BE SOLVED: To provide a small truing device adaptable to a general grinder using a super abrasive grain grinding wheel and capable of rotating a truing tool at a high speed without requiring a separate electric motor for rotationally driving the truing tool. SOLUTION: A device body is detachably mounted on a table where a work rotation driving device for the grinder is provided, and a driving member, an output member and a tool support are rotatably supported on a supporting shaft fixed to the device body. The rotation transmitted from the work rotation driving device to the driving member is increased in speed by a speed increasing mechanism and then transmitted to the output member and the rotation of the output member is transmitted to the tool support via joint means, thus causing the truing of the super abrasive grain grinding wheel with the truing tool mounted on the tool support.

摘要： PROBLEM TO BE SOLVED: To provide a small truing device capable of rotating a tooling tool at a high speed without separately mounting an electric motor to rotationally drive a tooling tool as a truing device suitable for a general purpose grinding machine using a super-abrasive grinding wheel. SOLUTION: A support shaft is removably supported at the workpiece supporting device of a grinding machine with rotation regulated. A drive member, an output member, and a tool support body are rotatably supported on the support shaft. Rotation transmitted from the workpiece driving mechanism of the workpiece supporting device to the drive member is boosted by a truing device and transmitted to an output member. Rotation of the output member is transmitted to a tool support body through a joint means and truing of the super-abrasive grinding wheel is executed by the tooling tool attached to the tool support body.

摘要： PURPOSE:To omit a work shifting device, and to shorten process time by providing a ram member which is fitted to a hollow hole of a working spindle, so that it can freely slide, and which is provided with a center on the front end, and a chuck that carries out gripping work on a proceeding end on the front surface of an engaging member. CONSTITUTION:A work W is carried by a loader and the like, and is temporarily put on a work temporary receiving rest, while a screw shaft 39 is rotated by means of the driving of a servo motor 42, and a ram member 28 having a nut member 40 proceeds in a working spindle 9, and a tail spindle of a tail stock is proceeded then, and the work W is supported by a center 29 as well as by the tail stock center in both ends. A chuck part C works as a gripper for the working spindle side end of the work W at the proceeding position of the ram member 28. A longitudinal direction end surface measurement device is proceeded at the same time, and the longitudinal position of the work W is measured thereby, and the servo motor 42 is driven by a controller based on the detection signal, and the positioning of the work W in a longitudinal direction is carried out by the moving forward/backward of the center 29 as well as the moving forward/backward of the tail stock center that follows the movement of the center 29.

摘要： PURPOSE:To control the attitude of a grinding liquid nozzle automatically so that the grinding liquid is properly supplied to the grinding point, throughout the diameter range of the grinding wheel from its maximum to the minimum in linkage with rotation of a grinding stone front cover, by guiding a cam follower installed on the nozzle slidably into a cam groove in a cam member, and coupling the nozzle with the front cover. CONSTITUTION:When a grinding wheel front cover 4 is rotated with axial movement of a working shaft 7 of an actuator 6, a grinding liquid nozzle 11 mounted coaxially on the working shaft 7 rotates round a cam follower 13 in the same direction as the front cover 4. At this time, the cam follower 13 is guided along the slope of a cam groove 9 in a cam member 10 fixed to the front cover 4, and the attitude of the nozzle 11 is so controlled as to be directed to the grinding point at all times. Thereby the grinding liquid is always fed to the grinding point properly.

摘要： PURPOSE:To eliminate necessity for changing the preparation for different works and provide possibility of processing such works of different types by furnishing a rotary work holder with a drive key detainable with the detent part of the end of work, and supporting this rotary work holder between a drive holder and a tail-stock center in such a way as rotatable. CONSTITUTION:When the type of a work to be processed W is entered by a data input/output device, the ram 2 of a tail-stock body 1 advances while a rotary work driving unit 10 does also to allow the detent part K of the work W to run against a drive key 41 of a rotary work holder 40. When these ram 2 and unit 10 further advance, the drive key 41 is pressed by the work W to compress a compression spring 42, and the rotary work holder 40 is rotated under guidance of cooperative action of a pawl on a drive holder 20 and a spiral groove in its cylindrical part 40A, and thus the drive key 41 is detained with the above-mentioned detent part K. At the same time, the ram 2 reaches the advanced position in accordance with the work W, and then a servo motor 23 is operated to rotate the rotary work holder 40 through the mentioned drive holder 20 and a transmission. Thus grinding of the work is conducted.

摘要： PURPOSE: To realize the grinding by providing a pin stroke correcting device which adjusts the deviation of a chuck and corrects the pin stroke to preliminarily correct each pin part while grinding the pin stroke after the grinding by the quantity corresponding to the error. CONSTITUTION: The phase division of a socket 43 of a chuck 11a is made to the position corresponding to a spindle 56 of a pin stroke correcting device 14a, and the position of the socket 43 is stopped on the same axis as that of the spindle 56. After a clamping device 22 is returned to the original position by this pin stroke correcting device 14a, the correction is read from the memory to slide the clamping device 22 by that quantity in the radial direction, and correction is made to the pin stroke of third and fourth pin parts to be ground next.

摘要： PURPOSE:To effect positive and negative correction of a taper by a method wherein a first slip member forms the boosting output side and a link mechanism to intercouple the first and second slip members with no clearance is provided therebetween. CONSTITUTION:When a taper is formed on a surface to be machined due to the mounting error of a workpiece, wear of a grinding stone, thermal deformation of each part of a grinding machine, and other reason, a prime mover 22 is run by means of an input responding to a correction amount, and a second slip member 27 on the input side is moved forward and backward through a screw mechanism 24. Forward and backward movement of the second slip member 27 on the input side is reduced and boosted to transmit it to a first slip member 15 through a link mechanism 18. A grinding stone shaft housing 7 on the regulation side is pressed by the first slip member 15 through a guide rail 13 and inclined around a resilient flexible part 11 serving as a fulcrum. The end part of the grinding stone housing 7 side on the regulation side of a grinding stone spindle 5 is displaced from the end part of the grinding stone shaft housing side on the other side by a correction amount, and the grinding stone spindle 5 is reversely inclined by an amount equivalent to a taper, resulting in removal of a taper at a grinding work.
