歯車と可動外歯車が回動される。As described above, the drive internal gear, the fixed external gear, and the rotatable planetary gear are arranged between the drive internal gear and the fixed external gear, and the planetary gear that receives the revolution is superposed on the planetary gear with a spindle. The movable internal gear and the movable external gear that are superposed on the internal gear and the fixed external gear mesh with each other, and the movable internal gear and the movable external gear each mesh with a pair of small gears. Parallel guide rollers are connected to each of the swivel links, and the guide rollers are formed in a cross beam shape as a whole.
Even if workpieces with different lateral dimensions are inserted, simply rotating the handle that is integrated with the drive internal gear facing the outside of the casing will rotate the planetary gear that is the planetary speed reduction mechanism inscribed in the drive internal gear while rotating. If only the revolution is transmitted to the second-stage planetary gear that is rotatably arranged with the planetary gear, the movable internal gear and the movable external gear are rotated.

らかの対向面に当接（接触）し挟むようになる。[0007] Since a pair of small gears meshing with the rotating movable internal gear and the movable external gear respectively rotate, the revolving links facing the front surface of the casing, which are the shaft ends of the respective small gears, respectively rotate. Of these, the parallel guide roller, which is a four-bar mechanism of one of the revolving links, is flattened, and comes into contact with (contacts) one of the opposing surfaces of the work.

ークの直交した残る面（短幅部分）に当接される。If the handle is further rotated, the movable internal gear or movable external gear on the guide roller side stopped by the contact of the work becomes immobile, but the movable external gear or movable gear on the other guide roller side becomes stationary. It does not become immovable with respect to the internal gear, so that the revolving rotation is given to the movable external gear or the movable internal gear while rotating further to the meshing planetary gear, and meshed with the movable external gear or the movable internal gear. The other small gear side rotates, the turning link at the shaft end of the small gear rotates, and the space between the other parallel guide rollers connected to this turning link is sequentially narrowed, and the remaining surface (short) of the workpiece is orthogonal.

る。That is, when one of the parallel guide rollers comes into contact with the work, the operation of the guide roller stops. For example, in the case of a work such as a rectangular bar having different vertical and horizontal dimensions, one parallel guide roller hits both surfaces of a long side portion which is a wide cross section and stops. At this time, the other parallel guide rollers are not yet in contact with the narrow cross-sectional side, and are appropriately separated by a gap. For this reason, if the handle is further turned, the movable external gear or the movable internal gear is rotated by the revolving operation of the planetary gear, and the other guide roller is further rolled by the deformation of the swivel link integrated with the small gear associated therewith. The gap is narrowed, and the guide roller eventually comes into contact with the work, where the centering (centering) is performed, and complete centering is completed as a whole.

る。As the fixing after the centering, if the handle for opening and closing and fixing the guide roller is turned and tightened tightly on the outer periphery of the casing, the driving internal gear projecting from the handle becomes immovable. Fix it. When the centering position is released after the predetermined work is completed, the handle is released in the opposite direction, and the handle is rotated in the opposite direction, so that the guide opening in the middle of the four guide rollers is widened. To enter a standby state.

When 8b is regarded as a pinion, when it is moved by an initial handle operation (a state where the guide rollers are not in contact with the four surfaces of the work), the planetary gear 18b, the movable external gear 5, and the movable internal gear 7
Both move by the amount as shown by arrow c. Here, it is assumed that one of the movable internal gears 7 is stopped due to contact with the work. That is,
When the movable internal gear 7 becomes immobile, the planetary gear 18b meshing with the movable internal gear 7 moves by the amount indicated by the arrow d while rotating, and the movable outer gear 5 facing the movable internal gear 7 rotates and rotates on the planetary gear 18b. Is moved by the added amount (that is, an amount twice the amount shown by the arrow d). Therefore, only the small gear 8 meshing with the movable external gear 5 rotates, and the turning link 10 at this shaft end performs a pinching operation on the remaining surface of the work A by the pair of guide rollers 11 remaining tilted.

される効果を奏する。As described above, according to the work guide centering device of the present invention, two external gears (a fixed external gear and a movable external gear) are opposed to each other in a disk-shaped casing in which a work insertion hole is provided. Two internal gears (drive internal gear, movable internal gear) and two separate planetary gears interposed in the middle are provided, and two small gears meshing with the movable external gear are interlocked with this. Since it is composed of a guide roller parallel to the revolving link and two small gears meshing with the movable internal gear side, the apparatus is compact and can be mounted on various apparatuses. Moreover, the centering operation of the work is performed only by turning the handle facing the outside of the casing protruding from the drive internal gear, and the planetary gear meshing with the drive internal gear rotates and revolves, and the other planetary gears overlapping with the planetary gear are rotated. By utilizing the characteristics of a planetary gear that has a decelerating effect that only the revolution can be taken out, the guide rollers arranged in a square (four-sided) arrangement as a whole hold the four sides of the work for centering. In this case, the two sets of parallel guide rollers are a parallel link roller and a turning link of a four-bar mechanism at the shaft end of a small gear meshing with a movable external gear, and are parallel deformed in the orthogonal direction to hold the work independently. -Even for a workpiece with a rectangular cross section with different lateral dimensions, it can be done by simply turning the handle step by step, and it becomes a one-touch center guide. Furthermore, since a two-stage planetary gear is used to reduce the speed by utilizing the characteristics of the planetary gear, two sets of parallel guide rollers can be moved by a light handle operation. Further, since the present invention performs the guide operation while the guide roller operates in parallel while the guide roller itself operates, unlike the conventional guide roller type which performs centering simultaneously in the X and Y directions, the effect of eliminating the work inclination phenomenon is eliminated. To play.
