Abstract

PROBLEM TO BE SOLVED: To make it possible to finely adjust the axial tilt and breadthwise tilt of a work and to securely insert an insert member into the work by engaging a specific number of screws with a positioning plate in the front-rear and right-left directions and allowing them to project from below, and finely adjusting the projection heights of those screws and adjusting the axial tilt and breadthwise tilt of the work. SOLUTION: At setting time, a handle 18 is loosened to rotate the positioning plate 7 sideward and rotate the positioning plate 7 upward, and three screws are finely adjusted in height and positioned so that the axial tilt and breadthwise tilt insert members 19 of the positioning plate 7 are correctly inserted. Then the positioning plate 7 is rotated downward and the three screws are made to abut against a fixed plate 12; and a rotary plate is rotated onto the positioning plate 7 and the handle 18 is rotated to fix the positioning plate 7. At this time, a work presser 13 fixes the work 3 at a specific position through springs 14 and 15. Then the insert members 19 are inserted into the work 3.

Is turned downward, the screws 28 and 29 abut against the fixing plate 30, the turning plate 34 is turned on the positioning plate 26, and the handle 3
6, the positioning plate 26 is fixed. At this time, the work holder 31 fixes the work 22 at a predetermined position via the springs 32 and 33. Next, the insertion member 37 is inserted into the work 22. When the work 22 or the insertion member 37 is changed, the positioning of the two is performed by the above operation.

[0004]

In the above prior art, the fine adjustment of the positional relationship between the work holder and the work cannot be performed only in the vertical direction before and after, and the fine adjustment in the horizontal direction cannot be performed. There was a problem that it could not be inserted securely.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, and a positioning plate which is placed on a transfer table on which a workpiece is intermittently transferred and which rotates vertically when stopped is fixed. In a work positioning device in which the work is pressed from above by a pressing plate and an insertion member is inserted from the axial direction, three screws are screwed into the positioning plate back and forth, left and right, and projected from below. The protrusion height of the three screws is finely adjusted so that the inclination in the work axis direction and the inclination in the width direction can be finely adjusted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail based on an embodiment shown in FIGS. Reference numeral 1 denotes a base on which a work 3 which is a main body such as a mechanical pencil is placed substantially horizontally on a transfer table 2 on a chain which is intermittently transferred. Reference numeral 4 denotes a lifter that pushes the transfer table 2 at a predetermined position stopped upward by a predetermined amount, and a roller 5 at the lower end is moved up and down by a cam 6. Reference numeral 7 denotes a positioning plate that rotates about a shaft 8,
One screw 9 is screwed in the work axis direction, and two screws 10 and 11 are screwed in the width direction at a predetermined axial distance from the screw 9 to project from below. The shaft 8 and the shaft hole of the positioning plate 7 can move not only vertically but also horizontally. Reference numeral 12 denotes a fixing plate with which the lower ends of the screws 9, 10, 11 abut. A work retainer 13 is connected to the end of the positioning plate 7 via springs 14 and 15.
Reference numeral 16 denotes a rotating plate that rotates about a shaft 17 of the fixed plate 12 on the side of the positioning plate 7, and the positioning plate 7 is pressed and fixed by the lower end of the handle 18 by the rotation of the handle 18. When setting, loosen the handle 18 and turn the rotating plate 1.
6 is rotated to the side of the positioning plate 7. Reference numeral 19 denotes an insertion member such as a core tank which is inserted into the mechanical pencil body 3 at a fixed position.

Next, the method of use will be described. When setting, loosen the handle 18 to position the positioning plate 7 as shown by the dotted line in FIG.
By turning to the side, the positioning plate 7 is turned upward, and the screws 9,
The height of the positioning plates 7 and 11 is finely adjusted, and the positioning plate 7 is tilted in the axial direction and the width direction. The positioning member 7 is positioned so that the insertion member 19 is correctly inserted. 10 and 11 are brought into contact with the fixed plate 12,
Is turned on the positioning plate 7 and the handle 18 is turned to fix the positioning plate 7. At this time, the work holder 13 is
The work 3 is fixed at a predetermined position via the work 4 and the work 15. Next, the insertion member 19 is inserted into the work 3.

[0008]

According to the present invention, the work is placed on the transfer table where the work is intermittently transferred, and the positioning plate which rotates vertically when the work is stopped comes into contact with the fixed plate, and the work is pressed from above by the holding plate. In a work positioning device in which an insertion member is inserted from an axial direction, three screws are placed on a positioning plate,
It is screwed to the left and right and protrudes from below, so that the protrusion height of the three screws can be finely adjusted to finely adjust the inclination in the work axis direction and the inclination in the width direction. The inclination and the inclination in the width direction can be finely adjusted, and the insertion member can be reliably inserted into the work.
