a second clamp plate 522, wherein the second clamp plate 522 is connected with the first clamp plate 521 in a sliding mode along the X-axis direction;

the first elastic member 523, the first elastic member 523 is disposed between the first clamping plate 521 and the second clamping plate 522. The sliding guide between the first clamping plate 521 and the second clamping plate 522 and between the first clamping plate 521 and the first sliding plate 51 are realized through different rod pieces; through the sliding connection of the first clamping plate 521 and the first sliding plate 51 along the Z-axis direction, the sliding connection of the second clamping plate 522 and the first clamping plate 521 along the X-axis direction, and the arrangement of the first elastic member 523, the clamping plate assembly 52 can slide along the Z-axis direction and can also be elastically telescopically adjusted along the X-axis direction.

Further, as shown in fig. 6, the clamping plate assembly 52 further includes:

a third clamping plate 524, wherein the third clamping plate 524 and the second clamping plate 522 are arranged in parallel and the third clamping plate 524 and the second clamping plate 522 are slidably connected, and the width of the clamping plate assembly 52 in the X-axis direction is adjusted. Since the width of the clamping plate assembly 52 relative to the X-axis direction is adjusted only by the first elastic member 523, the first elastic member 523 may be compressed too much to clamp the workpiece 100 too much to deform the workpiece 100, or the first elastic member 523 is loosened too much to clamp the workpiece 100, so that the width of the clamping plate assembly 52 along the X-axis direction can be further adjusted by providing the third clamping plate 524, thereby avoiding or reducing the problem that the clamping force is too large or too loose to cause insufficient clamping force due to too much compression of the first elastic member 523.

Further, as shown in fig. 1-2, the Y-axis direction of the table 11 is provided with a positioning assembly 6 for positioning the workpiece 100 in the Y-axis direction and capable of sliding and adjusting along the Y-axis direction.

Further, the positioning assembly 6 is fixed with the workbench 11 through other fixing assemblies by screws, the positioning assembly 6 comprises an L-shaped plate 61, and the L-shaped plate 61 is connected with the rack 1 in a sliding manner along the Y-axis direction;

a guide rod 62;

a second scale 63, the second scale 63 being arranged along the Y-axis direction;

and the positioning plate 64 is vertical and close to the second graduated scale 63, the positioning plate 64 is connected with the top end of the L-shaped plate 61 through a guide rod 62, and the guide rod 62 is connected with the machine frame 1 in the X-axis direction in a sliding manner. The length of the positioning plate 64 in the X-axis direction is smaller than the length of the smallest workpiece 100 to be machined in the X-axis direction to avoid the structural interference of the positioning plate 64 with the chucking assembly 52; according to the distance between the hole position of the workpiece 100 and the edge of the workpiece 100 along the Y-axis direction, the L-shaped plate 61 is pulled to adjust the position of the positioning plate 64 by contrasting with the second graduated scale 63, and then the L-shaped plate 61 is fixed with the workbench 11; when the workpiece 100 is placed, the workpiece 100 is directly placed on the table 11 while being attached to the positioning plate 64, thereby facilitating the positioning of the workpiece 100 along the Y-axis direction.

Further, as shown in fig. 1-2, a camera 7 is arranged on the positioning plate 64 close to the second scale 63, a display screen 71 is arranged on the rack 1, and the camera 7 is electrically connected with the display screen 71; because the workpiece 100 to be processed is long in the Y-axis direction, it is inconvenient for a person to manually check the position of the positioning plate 64, and the position of the positioning plate 64 on the second scale 63 is displayed in real time by the display screen 71 through shooting by the camera 7, so that the position of the positioning plate 64 can be conveniently adjusted manually.

The working steps are as follows: according to the distance from the hole position of the hole to be processed of the workpiece 100 on the workbench 11 to the edge, the position of the positioning plate 64 and the position of the slide rod 41 in the positioning assembly 6 in the Y-axis direction of the workbench 11 are adjusted, and the positions of the positioning plate 64 and the slide rod 41 are fixed;

the servo motor 14 drives the power screw rod 13 to rotate, so that the power screw rod 13 drives the clamping component 2 to slide on the power screw rod 13 to drive the drill bit component 3 to move, and the position of the required drill bit component 3 is adjusted;

meanwhile, the clamping assembly 5 is driven by the power screw 13 to clamp the workpiece 100;

then, the drill bit assembly 3 is started to work, and the workbench 11 is driven to move through the hydraulic cylinder 16, so that the workpiece 100 is close to the drill bit assembly 3 to drill a plurality of holes to be machined in the workpiece 100;

when the same workpiece 100 is processed in batches, the positioning assembly 6 only needs to be adjusted for the first time, the clamping assembly 2 and the sliding rod 41 do not need to be adjusted, when the clamping assembly 5 works, the power screw rod 13 is driven to rotate reversely to enable the clamping assembly 5 to loosen the workpiece 100, so that the workpiece 100 can be taken out, at the moment, the clamping assembly 2 can move, but under the condition that the position of the sliding rod 41 is not changed, when the power screw rod 13 rotates forwards to enable the clamping assembly 5 to continue to clamp the next workpiece 100, the clamping assembly 2 can reset and drive the drill bit assembly 3 to reset without adjustment.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
