plate members

9a, 9b, 9c, thereby enabling the

plate members

9a, 9b, 9c to be firmly clamped to the clamping seats 22, and then the

plate members

9a, 9b, 9c can be drilled.

Referring to fig. 10, the clamping method for clamping the

plates

9a, 9b, and 9c according to the first embodiment is further described:

plate members

9a, 9b, 9c are placed toward the clamping portions 224.

Step 82, in conjunction with fig. 13, drives the clamping portion 224 of each pair of clamping seats 22 to sink down from the corresponding chute 131 and drive the

corresponding plate

9a, 9b, 9c to descend until the

plate

9a, 9b, 9c is placed on the top surface 101.

Step 83, in conjunction with fig. 14 and 15, drives the clamping portions 224 of each pair of clamping bases 22 away from each other until they are separated from the

corresponding plate

9a, 9b, 9c, and then they rise again and protrude from the corresponding sliding slot 131 to be higher than the

corresponding plate

9a, 9b, 9c.

Step 84, with reference to fig. 16, the clamping portion 224 of each pair of clamping bases 22 is driven to approach and descend toward the

corresponding plate

9a, 9b, 9c to clamp the

corresponding plate

9a, 9b, 9c. Thereafter, the

plate members

9a, 9b, 9c are drilled.

Step 85, with reference to fig. 17, after the drilling operation is completed, the clamping portions 224 of each pair of clamping bases 22 are driven away from each other to separate from the

corresponding plate

9a, 9b, 9c.

Step 86, in conjunction with fig. 18, driving the clamping portions 224 of each pair of clamping seats 22 to sink from the corresponding sliding grooves 131 to be lower than the

corresponding plate members

9a, 9b, 9c and then to approach each other.

Step 87, referring to fig. 19, the clamping portion 224 of each pair of clamping bases 22 is driven to ascend and protrude from the corresponding sliding slot 131, thereby lifting the

plate members

9a, 9b, 9c up and away from the top surface 101.

Finally, the

plates

9a, 9b, 9c are taken out, step 88.

It should be noted that, as shown in fig. 9, in the first embodiment, three pairs of the clamping units 200 are used to clamp three positions before, during and after the

plates

9a, 9b and 9c, and in other variations, two pairs of the clamping units 200 can be used to clamp two positions before and after the

plates

9a, 9b and 9c, and the

plates

9a, 9b and 9c can be clamped stably.

In the first embodiment, the clamping driving member 21 of each clamping unit 200 is used to drive the three clamping seats 22 to move simultaneously, so that the three

plates

9a, 9b and 9c can be clamped simultaneously, the number of components can be reduced, and the cost can be reduced. In other variations, the clamping driving member 21 of each clamping unit 200 can simultaneously drive two or more clamping seats 22 to move, so as to simultaneously clamp two or more plates, and therefore, the number of the clamping seats 22 is not limited by the invention.

It can be understood that the present invention can also raise the

plate members

9a, 9b, 9c from the top surface 101 by the lifting driving member 222 driving the clamping portion 224 to rise, and further provide a space for the robot arm to clamp the

plate members

9a, 9b, 9c, which is helpful for achieving the full-automatic operation of the drilling machine.

Referring to fig. 20 to 22, a second embodiment of a clamping plate device of a drilling machine according to the present invention is similar to the first embodiment, with the difference that:

The clamping driving member 21 drives the clamping portion 224 of the clamping seat 22 to move in the sliding slot 131, so that the plate 9a is clamped in the clamping seat 22 and six clamping points are formed. In the second embodiment, one of the clamping driving members 21 is used to drive one of the clamping bases 22 to move, so that the clamping force is better.

Referring to fig. 23, the lifting driving member 222 can drive the clamping portion 224 of the clamping member 223 to move toward the top side to extend out of the top surface 101, and can also be used to lift the plate 9a for taking and placing materials.

In summary, the clamping plate device of the drilling machine of the present invention utilizes the clamping driving member 21 to drive the clamping base 22 to clamp the

plates
