不可能であるため専用工具を必要とした。(Prior art) Pins, such as jig positioning pins used to place a workpiece in a fixed position relative to a cutter, are usually tightly attached or press-fitted into a jig plate. implanted. Therefore,
Even if the pin was to be removed from the jig plate after the machining operation was completed, a special tool was required since it was almost impossible to pull it out by hand.
そこで、このような専用工具として、例えば、

部品を引き抜くようにしたものであつた。 Therefore, as such special tools, for example,
There was one disclosed in Utility Model Application Publication No. 53-35499.
As shown in FIG. 3, the device of the same number has a slider 23 slidably attached to a shaft 22 of a main body 21, and flanges 24, 25 are provided at both front and rear ends of the shaft 22. A bolt 26 is fixed to the front flange 24, and a tightening nut 2 is screwed onto the bolt 26.
7, a threaded bolt 28 that is screwed into a screw hole of the pull-out part is integrally tightened and fixed. Therefore, the pull-out part is pulled out by the impact force generated when the slider 23 collides with the rear flange 25.

のを防ぐため受け金８が介装されている。 A cylindrical hammer member 4 is attached to the pull-out rod 3 and is inserted through the pull-out rod 3 with some play so that it can slide up and down smoothly. In order to prevent the attached hammer member 4 from coming off, a stopper pin 5 is driven near the front end of the pull-out rod 3. Further, an appropriate impact receiving member is provided on the proximal end side to absorb the impact caused by the upward movement of the hammer member 4. For example, in this embodiment, a double nut 7 is attached to the proximal threaded portion 6. is screwed on,
In addition, a receiver 8 is interposed to prevent the hammer member 4 from directly colliding with the nut 7.

る。 The front end of the pull-out rod 3 is formed with a mounting part 10 in which a screw hole 9 opening in the axial direction is screwed, and a notch step part 11 for attaching a wrench is provided at the rear of the mounting part 10. When attaching the pin extracting member 2, the entire extracting rod 3 can be fixed using a tool such as a spanner.

抜き爪１５が相対抗するように形成されている。 The pin extraction member 2 is formed into a substantially U-shaped cross section so that it can sandwich and cover a pin, for example, a large round-headed positioning pin P for a jig with a rounded top surface from above. It has a main body 13. A male screw 12 is provided at the base end of the main body 13 to be screwed into the mounting portion 10 of the pull-out rod 3.
is provided. Moreover, a pair of extracting claws 15 are formed at the tip thereof to engage with both recesses 14, such as notches, provided on the outer periphery of the lower surface of the head of the pin P so as to sandwich the shaft part. has been done.

る。 Next, handling of the extracting tool configured in this way will be explained. The pin P is press-fitted into a reference hole type jig plate J. First, the extraction member 2 is attached to the extraction rod 3. Then, the first
As shown by the arrow X in the figure, the member 2 is moved laterally parallel to the head of the press-fitted pin P, and the pair of extraction claws 15 are provided on the outer periphery of the lower surface of the head. Engage with the recess 14. Therefore, as shown in FIG.
It is worn so as to sandwich and cover the head of the person from above. At this time, the hammer member 4 attached to the pull-out rod 3 is moving downward together with the receiver 88 due to its own weight, and is supported by the stopper pin 5 driven into the front end of the pull-out rod 3. .

れることとなる。 Then, the hammer member 4 in a stationary state is moved upward with force, and is caused to collide with the nut 7 via the receiver 8 (as shown by the imaginary line in FIG. 2). After a collision, it quickly returns to its downward motion and then moves upward again with momentum. In this way, as the hammer member 4 is moved up and down several times, the pin P is pulled out from the jig plate J due to the impact of the hammer.
なお、この実施例では、頭部上面がアール面と
なつている位置決めピンを引き抜く例について説

付けできる構成としても良い。 In addition, various changes can be made to the configuration without departing from the gist of the invention. For example, the design can be changed to any desired configuration, such as integrally molding an impact receiving member for receiving hammer impact at the base end of the pull-out rod 3, or changing the double nut to a cap nut, a nut with a seat, etc. . Furthermore, the attachment part formed on the front end of the pull-out rod 3 is not a screw hole but a male screw threaded on the outer periphery of the front end of the pull-out rod 3, and on the other hand, a female screw is provided on the pull-out member 2 side to be screwed with the male screw. In some cases, it may be detachable. Further, the drawing member 2 may be configured to be detachably attached by an appropriate means other than screws.

効率良く引き抜き作業を進めることができる。(Effects of the invention) As is clear from the detailed explanation above, the pin extraction tool according to this invention only requires a recess for extraction to be machined on the outer periphery of the lower surface of the pin head such as a locating pin, and the tool is press-fitted. The attached pin can be easily pulled out without damaging it. Furthermore, when pulling out, the attachment is completed by simply moving the pull-out member provided at the tip of the tool in parallel with the head of the pin from the side, making attachment easier and requiring less effort to pull out.
The extraction work can be carried out efficiently.
また、引き抜き対象であるピンの頭部上面には
なんらの加工を施す必要がないため、機能上その
上面にネジ穴加工などができないようにピンにつ
いても使用することができる。 Furthermore, since there is no need to perform any processing on the top surface of the head of the pin to be pulled out, it can also be used for pins that are functionally unable to machine screw holes or the like on the top surface.

The pin can be pulled out with a small amount of force.
