The present invention relates to a clamping finger of the automatic sheet feeder (Clamping Finger), and more particularly, as a clamping finger of the automatic sheet feeder Automatically supplying, discharging and conveying a thin plate efficiently clamping in a limited space below the plate It is to be done.

Conventionally, there is no device for automatically performing plate work, so a simple separation tool is used for supplying, discharging, and transporting a plate, or a user manually works on a processing machine, resulting in a lot of inconvenience when working, There was a problem such as falling off productivity significantly.

The present invention is to solve the above-mentioned problems, the present invention is to automatically supply, discharge and transport the thin plate by clamping the automatic plate feeder which can significantly improve productivity by clamping efficiently in the limited space below the plate The purpose is to provide a finger.

In order to achieve the above object, the present invention is a plate fixed to the body bracket, the cylinder is installed in the hinge hinged to the cylinder bracket of the plate and the cylinder which is moved forward and backward by the pneumatic cylinder is fixed to the plate, The clamping body is provided with a spring to give elasticity to the tie bar, the stopper block fixed to the tie bar and the plate and the cam pole connected to the clamping of the plate is hinged, and the rod of the cylinder clamps and unclamps the forward and backward plates. Clamping finger of the automatic plate feeder comprising a clamping lever, a lever plate hinged to the cylinder joint, the clamping body and the clamping lever to guide clamping and unclamping of the clamping lever, and a cover installed on the plate to protect the parts. to be.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

Figure 1 a and b is a longitudinal cross-sectional view showing the operating state at the time of unclamping and clamping of the present invention, Figure 2 is a cross-sectional view showing the present invention, the body bracket (1) of the clamping finger is fastening member (2) and nut It is fixed by the plate (3), the plate (4) is fixed on the body bracket (1), the cylinder bracket (5) is fixed to the upper portion of the plate (4), the cylinder (5) to the cylinder (6) The upper end of the hinge is coupled to the pin (7), the end of the rod (8) of the cylinder (6) is connected to the upper end of the cylinder joint (9).

In addition, an upper end of the spring 11 is fixed to the clamping body 10 fixed to the lower part of the plate 4 by a pin 7a, and a lower end of the spring 11 is the long hole 12 of the clamping body 10. The hinge is coupled to the pin (7a) with the upper end of the tie bar 13, the lower end of the tie bar 13 is hinged to the lower end of one side of the clamping lever 14 by the pin (7b), The upper end of the clamping lever 14 is hinged with the pin 7c together with the cam 15.

In addition, an upper end of the lever plate 16 is hinged to the lower end of the cylinder joint 9 by a pin 7d together with the spacer 17, and a central side of the lever plate 16 is pinned to the clamping body 10. 7e is hinged, and the lower end of the lever plate 16 is hinged to the clamping lever 14 with a pin 7f.

In addition, a stopper block 19 to which the clamping lever 14 is connected to the cam pole 15 when the plate 18 is clamped is fixed to one side of the lower end of the plate 4, and a lower end of the plate 4. The reference block 20 is fixed to clamp the upper surface of 18), and a cover 21 is provided on the plate 4 to protect the components.

As shown in FIG. 1 and FIG. 2, the present invention configured as described above has a cylinder bracket 5 on the plate 4 fixed on the body bracket 1 when clamping the plate 17 with the clamping finger. When air is supplied to the hinged cylinder 6 in the state shown in FIG. 1a, the rod 8 of the cylinder 6 is advanced, and the cylinder joint 9 connected to the end of the rod 8 is advanced. The lever plate 16 hinged at the lower end of the cylinder joint 9 by the pin 7d together with the spacer 17 is rotated about the pin 7e hinged to the clamping body 10 at the center thereof. You exercise.

At the same time, as the clamping lever 14 hinged by the pin 7f at the bottom of the lever plate 16 and the lever plate 16 is moved, the lower end is hinged by the pin 7b at the bottom of one side of the clamping lever 14. As the combined tie bar 13 is tensioned, the spring 11, which is hinged at the bottom by the pin 7a, is tensioned with the upper end of the tie bar 13 to the long hole 12 of the clamping body 10.

At the same time, the upper end of the clamping lever 14 is connected to the stopper block 19 fixed to the lower end side of the plate 14 at the same time the cam pole 15 hinged together by the pin 7c. 15, the clamping lever 14 clamps the plate 18 connected to the reference block 19 fixed to the lower end of the plate 4 as shown in FIG. 1B.

In addition, when unclamping the plate 18, as air is supplied to the port opposite to the cylinder 6, the reverse operation is performed in the above reverse order to return to the state shown in FIG.

As described above, the present invention efficiently installs the plate 18 in a limited space below the plate 18 as the rod 8 of the cylinder 6 installed on the clamping finger and operated by the supply of air moves forward and backward. By clamping and unclamping, the plate 18 can be automatically supplied, discharged, and transported to improve productivity, thereby greatly improving the efficiency and reliability of the device.
