サイクルに入る。 For example, in the case of the workpiece W1 , the position of the movable secondary notch pin 4 is shifted to the position corresponding to the notch hole pitch of the workpiece W1 , and the transfer device is advanced to move the workpiece W1 to the position of the notch hole pitch on the device body 1. Bring it to the 0 position, lower the transfer device, stop halfway, and release the clamp. Then transfer direction TR
The stopper shaft of the stopper 27 is moved to a predetermined position, the movable bar 16 is rotated to rotate the engaging claw 17 to the position where it engages with the workpiece W1 , and the movable bar 16 is moved forward to start the workpiece. Stop object W 1 2
7 along the guide block 38 in the transfer direction TR. Thereafter, the transfer device is moved down to the lowering end and the workpiece W1 is placed on the seat pad 2. At the same time, the stopper 28 in the direction perpendicular to the transfer direction TR
Move the stopper shafts 29 of a and 28b to a predetermined position, actuate the rotating lever 25 of the shift device 24 that pushes in a direction perpendicular to the transfer direction TR,
The workpiece W1 is pushed until it comes into contact with the stoppers 28a and 28b. As a result, the pair of knock pins formed on the workpiece W1 correspond to the fixed main knock pin and the movable sub-knock pin 4. Then, by engaging the fixed main knock pin 3 and the movable sub-knock pin 4 with the pair of notch holes of the workpiece W1 , the workpiece
W 1 is positioned at the processing center position P 1 . After that, the jig is tightened as usual and the machining cycle begins.

Transfer direction TR by the required amount from point W 0 position
When the stopper axis of the stopper 27 is moved by a predetermined amount in order to move the workpiece W1 and make the amount of movement different from that of the workpiece W1 , and also to move the stopper shaft of the stopper 27 by a predetermined amount in a direction perpendicular to the transfer direction TR to the center position P2' during machining. Stoppers 28a, 28b are used to change the amount of movement of
The stopper shaft 29 is also moved. In this way, the workpiece W 2 is shifted in the transfer direction TR by the engagement claw 17 as described above, and the workpiece W 2 is shifted in a direction perpendicular to the transfer direction TR by the rotary lever 25, so that the fixed main body The dowel pin 3 and the movable auxiliary dowel pin 4 are engaged with a pair of notch holes in the workpiece W2 for positioning.

われ、生産性並びに位置決め精度を向上する。<Effects> As described above, according to the device of the present invention, the stopper is finely adjusted forward and backward in the transfer direction and in two directions perpendicular to the transfer direction depending on the type of workpiece to regulate the shift position of the workpiece, and the fixed main Of the two dowel pins, the dowel pin and the movable sub-knot pin, the pitch of the movable sub-knot pin relative to the fixed main dot pin is arbitrarily changed using a feed screw mechanism, and the pitch is changed to the dot hole according to the notch hole pitch based on the type of workpiece. Because it is configured to engage, even if multiple types of workpieces are randomly brought in, not only with different notch hole pitches, but also with different notch hole positions in two directions: the transfer direction and the direction perpendicular to this direction. Positioning work for the workpiece can be performed quickly, improving productivity and positioning accuracy.

たことを特徴とする工作物位置決め装置。1 A device for positioning a rectangular block-shaped workpiece, which includes a fixed main dowel pin that engages and disengages from one of a pair of notch holes provided in the workpiece that serves as a positioning reference, and a fixed main dowel pin that engages and disengages from the other notch hole. A movable sub-knock pin that engages and disengages, a knock-pin advance/retreat movement device that moves the fixed main knock pin and the movable sub-knock pin forward and backward in the axial direction in synchronization, and a knock pin feed screw mechanism that adjusts the pitch of the movable sub-knock pin with respect to the fixed main knock pin. A movable auxiliary knock pin moving device that can be arbitrarily changed and positioned to correspond to the other notch hole, a transfer device that conveys the workpiece, and a stopper feed screw mechanism that allows fine adjustment of forward and backward movement depending on the type of workpiece. and a stopper for regulating the transfer direction of the workpiece, a stopper for regulating the direction perpendicular to the transfer direction, and a shift device for pushing the workpiece to the stoppers in the two different directions. Characteristic workpiece positioning device.
