Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A workpiece processing auxiliary fixing structure includes a base 1, an mounting block 19 is provided on the top of the base 1 for mounting a support rod 3, and four rectangularly distributed pillars 2 are fixedly connected between the lower end of the mounting block 19 and the base 1 for supporting the mounting block 19. The upper and lower ends of the pillars 2 are fixedly fitted with fixing rings to improve the stability of the pillars 2. The opposite sides of the two fixing rings are fixedly connected to the upper ends of the mounting block 19 and the base 1, respectively.

[0022] In this embodiment, the mounting block 19 has a square groove that is open at both the top and bottom. A movable block 5 is slidably connected to the inner wall of the square groove for adjusting the left and right positions of the workpiece. Two horizontally arranged support rods 3 are slidably inserted into the movable block 5 for supporting and guiding the movable block 5. The two ends of the support rods 3 pass through the movable block 5 and are fixedly connected to the inner wall of the square groove. An electric push rod 4 is fixedly inserted into the inner right side of the square groove for driving the movable block 5 to move. One end of the electric push rod 4 is fixedly connected to the movable block 5, and the other end of the electric push rod 4 passes through the mounting block 19.

[0023] In this embodiment, the upper end of the movable block 5 passes through the square groove. A vertically arranged first support plate 9 is fixedly connected to the upper end of the movable block 5 and near the right edge to support the first cylinder 16. A connecting plate 10 is rotatably connected to the left side wall of the first support plate 9 to install the connecting block 11. A square block 14 is fixedly connected to the right side of the connecting plate 10 to prevent the connecting plate 10 from loosening. A storage groove corresponding to the square block 14 is provided on the left side of the first support plate 9. One end of the square block 14 extends into the storage groove. A first clamping block 15 is provided at the upper end of the square block 14 to press down and clamp the square block 14. A first cylinder 16 is fixedly inserted into the top of the storage groove to drive the first clamping block 15 to rise and fall. The upper end of the first cylinder 16 passes through the first support plate 9.

[0024] In this embodiment, the lower end of the first clamping block 15 is fixedly connected to the locking block 18, which is used to lock the square block 14 with the locking slot. There are multiple locking blocks 18. The upper, lower and front and rear sides of the square block 14 are provided with locking slots corresponding to the locking blocks 18. The lower end of the locking block 18 slides into the locking slot. The lower end of the first cylinder 16 is fixedly connected to the upper end of the first clamping block 15. The end of the square block 14 away from the connecting plate 10 is fixedly connected to the connecting rod 17, which is used to support the square block 14. The end of the connecting rod 17 away from the square block 14 is rotatably connected to the inner side wall of the storage slot.

[0025] In this embodiment, a connecting block 11 is fixedly connected to the left side of the connecting plate 10 for supporting the workpiece. The end of the connecting block 11 away from the connecting plate 10 is provided with a slot. The upper and lower sides of the slot are slidably connected with second clamping blocks 12 for clamping the workpiece. The opposite sides of the two second clamping blocks 12 are fixedly connected with second cylinders 13 for driving the second clamping blocks 12 to rise and fall. The end of the second cylinder 13 away from the second clamping blocks 12 passes through the connecting block 11. The second cylinder 13 and the connecting block 11 are fixedly connected.

[0026] In this embodiment, a vertically arranged second support plate 7 is fixedly connected to the upper end of the movable block 5 and near the left edge to support the third cylinder 6. The third cylinder 6 is fixedly inserted into the right side of the second support plate 7 to drive the third clamping block 8 to move. One end of the third cylinder 6 passes through the second support plate 7, and the other end of the third cylinder 6 is rotatably connected to the third clamping block 8 to provide a certain support for the workpiece.

[0027] In this embodiment, firstly, the base 1 is securely installed on the workbench of the bench drill. Then, the workpiece is inserted into a preset slot. Next, the second cylinder 13 is activated, driving the second clamping block 12 to reliably clamp and fix the workpiece. At this point, the bench drill can be used to drill holes in the workpiece. Simultaneously, the first cylinder 16 is activated, causing the first clamping block 15 to rise, which in turn drives the locking block 18 to rise as well. At this time, the user can manually rotate the connecting block 11, easily rotating and flipping the workpiece, facilitating drilling operations on the front, back, top, and bottom surfaces of the workpiece. When specific drilling is required... When the surface is rotated to the upward position, simply restart the first cylinder 16 to drive the first clamping block 15 to descend, clamping and pressing the square block 14. The descent of the first clamping block 15 will also cause the locking block 18 to insert into the slot, further locking the square block 14 and effectively preventing the connecting plate 10 and the connecting block 11 from rotating or loosening. Finally, start the third cylinder 6 to drive the third clamping block 8 to move to the right, so that it tightly presses against the workpiece, thereby significantly improving the stability during the processing. At the same time, start the electric push rod 4 to drive the moving block 5 to move left and right, so that the user can easily adjust the drilling position of the workpiece.

[0028] As described above, electric actuators and cylinders are existing mature technologies, and their working principles and internal structures are known to those skilled in the art. This application only utilizes their functions and does not improve their internal structures; therefore, it will not be described in detail.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
