After the processing is completed, the left inclined rod 27 is reset, driving the conveying plate 25 to reset accordingly, and the workpiece 5 is left at the center of the processing table 2. At this time, the right inclined rod 27 moves toward the direction of the processing table 2, driving the push plate 20 to move accordingly, thereby pushing the processed workpiece 5 away from the processing table 2. During the resetting process after the processing is completed, a new unprocessed workpiece 5 is replaced at the bottom of the conveying plate 25, and the above steps are repeated, so that continuous alternating loading and unloading of the workpiece 5 can be realized, thereby fully improving the processing efficiency. When the driving shaft 35 rotates, the driving wheel 36 is driven to rotate accordingly, so that the driven wheel 42 meshed with it through the transmission belt 37 starts to rotate. When the driven wheel 42 rotates, it drives the transmission shaft 40 at its center to start to rotate. When the transmission shaft 40 rotates, it drives the driving bevel gear 41 at the bottom to rotate accordingly. When the driving bevel gear 41 rotates, it drives the driven bevel gear 10 meshed with the bottom edge to start to rotate, so that the two-way threaded rod 8 rotates accordingly. When the two-way threaded rod 8 rotates, it drives the movable blocks 9 threadedly connected on both sides thereof to approach or move away synchronously. When the movable block 9 moves, it drives the fixed rod 6 at its top to move accordingly, so that the connecting block at the top of the fixed rod 6 moves along the The second slide groove 4 starts to slide, and the movement of the connecting block drives the mounting plate 11 on its top to move synchronously. The movement of the mounting plate 11 drives the drilling motor 12 on the top to move accordingly. The drilling motor 12 is started during drilling, so that the drilling motor 12 drives the tool holder 16 to start rotating through the rotating shaft 14 during the synchronous movement toward each other. The rotation of the tool holder 16 drives the drill bit 17 to start rotating, so that the left and right side walls of the workpiece 5 can be drilled more synchronously at multiple stations during processing, thereby further improving the processing efficiency. The synchronous movement of the multi-station drilling motor 12 can ensure the processing accuracy and consistency of the product, thereby improving the processing quality.

[0032] When the mounting plate 11 moves, the connecting rod 18 is driven to move accordingly, so that the clamping plate 26 connected to the other end of the connecting rod 18 moves accordingly, until the clamping plate 26 abuts against the side wall of the workpiece 5. With the continuous movement of the mounting plate 11, the connecting rod 18 moves toward the inside of the clamping plate 26. At this time, the spring 19 is compressed, and the clamping plate 26 generates an elastic force toward the workpiece 5, thereby clamping and fixing the workpiece 5 during the drilling process to prevent the workpiece 5 from being deflected during processing; when the connecting rod 18 moves, it drives the first push block 43 at the other end thereof to move in the direction of the workpiece 5, so that the second push block 47 slidably connected thereto through the inclined surface moves upward, and when the second push block 47 moves upward, it drives the vertical rod 46 at the top to move upward, and when the vertical rod 46 moves upward, it drives the positioning block 45 to move upward, so that the lower slot 49 at the top of the positioning block 45 moves in the direction of the upper slot 48, until the lower slot 49 is in close contact with the upper slot 48, surrounding a positioning hole, positioning the drill bit 17 during drilling, and fully improving the drilling accuracy.

[0033] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
