[0029] S2: The telescopic end of the first cylinder pushes the connecting plate to move. The connecting plate drives the moving plate to move up and down along the inner wall of the rectangular groove.

[0085] Structure description:

[0086] Vertical drilling machine body 1: The vertical drilling machine body 1 is of an existing structure, and its working principle is explained in detail as follows:

[0087] I. Main components and functions

[0088] Base: Provides stable support to ensure that the drilling machine does not shake during drilling.

[0089] Column: Connects the base and the main machine part, providing support and guidance.

[0090] Main machine: Includes a motor and a transmission system. The power of the motor is transmitted to the main shaft gearbox through a belt, and then transmitted to the main shaft after speed change by the main shaft, so that the main shaft drives the drill bit to rotate.

[0091] Main shaft and drill bit: The main shaft is fixed on the column and can rotate, driven by the motor, and the speed can be adjusted. The drill bit is the core component of the drilling machine, responsible for the actual drilling operation. The rotation of the main shaft creates the rotational kinetic energy for drilling, and at the same time, the main shaft drives the drill bit into the workpiece and starts drilling.

[0092] Feeding device: Controls the depth and speed of the contact between the drill bit and the workpiece. Vertical drilling machines usually have a rapid feeding device, enabling the workpiece to be quickly moved to the correct position. At the same time, the axial feeding movement of the main shaft can be automatically or manually controlled by the feed box.

[0093] II. Working process

[0094] Position the workpiece: Place the workpiece to be machined on the workbench and fix it with a fixture to ensure that the workpiece does not move during drilling.

[0095] Select the drill bit: Select a suitable drill bit according to the requirements of different materials and hole diameters. The type and diameter of the drill bit will affect the depth and accuracy of the hole.

[0096] Start the drilling machine: Turn on the power, the motor starts to run, driving the drill bit to rotate. The speed of the drill bit can usually be adjusted to meet the drilling requirements of different materials.

[0097] Feeding: Make the main shaft move downward through the feeding device, driving the drill bit to slowly contact the workpiece. During this process, the drill bit cuts the material while rotating, gradually forming a hole.

[0098] Removing cutting substances: The rotation of the drill bit and the downward movement of the main shaft create a cutting force, which removes the cutting substances on the workpiece to complete drilling.

[0099] Coolant supply: During the drilling process, vertical drilling machines usually supply coolant to cool and lubricate the drill bit and the workpiece, preventing overheating and extending the tool life.

[0100] Complete drilling: Once the drilling reaches the predetermined depth, the main shaft stops rotating and can be moved upward through manual or automatic control, and the worker can take out the drilled workpiece.

[0101] Vertical drilling machine mounting base 4: The vertical drilling machine mounting base 4 is used to mount the vertical drilling machine body 1.

[0102] Cylinder mounting groove 17: The cylinder mounting groove 17 is used for the installation of the third cylinder 15.

[0103] Guide groove 16: The guide groove 16 is used for the installation of the guide plate 10.

[0104] Guide plate 10: The guide plate 10 cooperates with the guide groove 16 to assist in the movement of the rectangular fixing plate 20.

[0105] Fixed rod 5: The fixed rod 5 is used to fix and drive the fixed clamping plate 7 to move.

[0106] Rectangular groove 19: The rectangular groove 19 is used for the installation of the moving plate 3.

[0107] First cylinder 2: The first cylinder 2 drives the moving plate 3 to move up and down through the connecting plate 21.

[0108] Mounting bottom plate 18: The mounting bottom plate 18 is used for the installation of the first cylinder 2.

[0109] Third cylinder 15: The third cylinder 15 is used to drive the rectangular fixing plate 20 to move left and right.

[0110] Second rectangular mounting groove 14: The second rectangular mounting groove 14 is used for the installation of the positioning plate 24.

[0111] First rectangular mounting groove 13: The first rectangular mounting groove 13 is used for the installation of the clamping plate 25.

[0112] Pushing plate 26: The pushing plate 26 is used to fix and drive the clamping plate 25 to move.

[0113] Second cylinder 9: The second cylinder 9 is used to push the pushing plate 26 to move.

[0114] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.

After the fixed clamping plate (7) approaches the fixed position, start the first cylinder (2). S2: The telescopic end of the first cylinder (2) pushes the connecting plate (21) to move. The connecting plate (21) drives the moving plate (3) to move up and down along the inner wall of the rectangular groove (19). The moving plate (3) drives the fixed clamping plate (7) to move up and down through the fixed rod (5), so as to adjust the up and down fixed position of the fixed clamping plate (7) to adapt to different up and down fixed positions of the workpiece. S3: After the up and down fixed position of the fixed clamping plate (7) is adjusted, stop the first cylinder (2), and start the third cylinder (15) again to push the fixed clamping plate (7) to move to fix the workpiece. Among them, the movement modes of the other multiple third cylinders (15) and the first cylinder (2) are the same, and the multiple third cylinders (15) and the first cylinder (2) are all independently controlled. Among them, by setting the fixing components, the moving distance and up and down position of the multiple fixed clamping plates (7) can be adjusted according to the specific shape of the workpiece to adapt to the fixing of workpieces with different shapes. And the fixing method uses a point-fixing method to fix the specific fixing position of the specific shape of the workpiece, and the fixing is firm. S4: When installing the entire mounting base (11), first, the staff can use welding or other methods to fixedly connect the two mounting plates (22) to the left and right sides of the vertical drilling machine mounting base (4) as a whole, and then take out the entire mounting base (11). S5: Place the entire mounting base (11) above the vertical drilling machine mounting base (4), and then move the entire mounting base (11) downward so that the upper ends of the two positioning plates (24) respectively slide through the inner walls of the corresponding second rectangular mounting grooves (14). When the upper surfaces of the two support sleeves (23) are both in contact with the lower surface of the mounting base (11), the installation of the entire mounting base (11) is completed. Among them, then start multiple second cylinders (9); S6: The expansion and contraction of multiple second cylinders (9) push two push plates (26) to move towards opposite positions, thereby pushing four clamping plates (25) to be respectively clamped against the inner walls of the corresponding first rectangular mounting grooves (13). When the opposite surfaces of the two push plates (26) are respectively in contact with the corresponding fixed plates (12), the overall installation of the mounting base (11) is completed. Among them, the working principle of the overall disassembly and installation of the mounting base (11) is the same, but the movement direction is opposite.
