Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, and in particular to a drilling machine that prevents plate displacement. Background Technology

[0002] Drilling technology is frequently used in the processing and production of sheet metal. However, in the existing technology, the sheet metal to be processed by the drilling equipment of drilling machine technology usually needs to be clamped and fixed to prevent the sheet metal from shifting during drilling, which would affect the accuracy of drilling and cause waste of sheet metal.

[0003] Chinese Patent Publication No. CN219234018U discloses a CNC drilling machine for sheet metal, which includes a worktable, a drill base, and a drill bit. A dustproof cylinder is provided on the drill base, and a dustproof cover is slidably connected to the outside of the dustproof cylinder. The dustproof cover can be moved to cover the sheet metal to be processed. The dustproof cylinder is provided with an elastic component that causes the dustproof cover to move away from the drill base. A dust collection chamber is opened in the dustproof cylinder. A vacuum cleaner is also provided on the drill base, and the vacuum cleaner is connected to the dust collection chamber through a vacuum pipe.

[0004] The existing technical solutions have the following shortcomings: the current drilling machines are not convenient for fixing the plates. The technical solutions lack a structure for fixing and clamping the metal plates during use, which can easily cause the plates to shift during processing, causing the drilling position to shift, thereby reducing the accuracy of the drilling machine and affecting the drilling quality. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a drilling machine that prevents plate displacement, so as to solve the problem mentioned in the background art that existing drilling machines are inconvenient to fix plates and that plates are prone to displacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling machine for preventing plate displacement, comprising a base and a support block, wherein a guide rod is provided on one side inside the base, and a guide block is sleeved on the outside of the guide rod, a servo motor is connected to one side of the base, and a connecting rod is connected to one side of the servo motor, a drive gear is sleeved on the outside of the connecting rod, and a movable toothed plate meshes on one side of the drive gear, and a support block is provided at the top of both the movable toothed plate and the guide block;

[0007] The support block consists of two blocks connected by a horizontal plate. An electric telescopic rod is installed at the top of the horizontal plate, and a rotary motor is connected to one end of the electric telescopic rod. A drill bit is connected to one end of the rotary motor. Cylinders are installed at both ends of the bottom of the horizontal plate. A fixing block is connected to the bottom of the cylinder. A threaded rod is installed inside the fixing block. A sleeve block is sleeved on the outside of the threaded rod. A limit mechanism is installed on one side of the sleeve block.

[0008] Preferably, a first inner groove is provided on one side of the base, and a second inner groove is provided on the other side of the base.

[0009] Preferably, the cross-section of the sleeve block is rectangular, two sleeve blocks are provided, and two sets of limiting mechanisms are provided.

[0010] Preferably, the limiting mechanism includes a fixing frame, which is disposed on one side of the sleeve block. A pressure rod passes through the interior of one end of the fixing frame, and a limiting block is provided at one end of the pressure rod. A handle is threadedly connected to the other end of the pressure rod.

[0011] Preferably, the cross-section of the fixing frame is an inverted "L" shape, and the top of the fixing frame is provided with a groove, the cross-section of the groove being annular.

[0012] Preferably, a rubber pad is connected to one side of the fixing frame, and rubber protrusions are evenly distributed on the bottom of the limiting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the drilling machine for preventing plate offset achieves easy fixation and improves the accuracy of plate processing;

[0014] By using a cylinder, the fixed block is driven to move downward, moving the sleeve block to the required position. The threaded rod is rotated outward, causing the sleeve block to move horizontally. Simultaneously, the sleeve block slides on the limit rod for support, which improves the stability of the sleeve block's movement. There are two sets of sleeve blocks. The width of the plate placement position can be adjusted by adjusting the distance between the sleeve blocks. When the sleeve block moves to the required position on the plate, a positioning pin can be inserted into the fixed block to prevent the threaded rod from rotating when it stops, thus affecting the accuracy of the sleeve block.

[0015] By moving the sleeve blocks to the desired position as described above, the plate is placed between the sleeve blocks and clamped and fixed by the fixing frame and rubber pads to prevent the plate from shifting during drilling. The rubber pads also protect the clamping area of ​​the plate to prevent external damage. Next, the handle is rotated inside the groove. Since the handle and the pressure rod are connected by threads, even if the handle drives the pressure rod to move downward, the limiting block will then press against the plate, which will facilitate further clamping and fixing of the plate, improve the stability of the plate during drilling, and improve the drilling accuracy of the drilling machine. In addition, the bottom of the limiting block is evenly provided with rubber protrusions, which protect the outside of the plate and prevent external damage to the plate during clamping and fixing.

[0016] By activating the servo motor, the connecting rod is rotated, causing the drive gear and the moving gear plate to mesh. This causes the moving gear plate to move back and forth inside the second inner groove. Simultaneously, the moving gear plate drives the support block to move back and forth, and the guide block slides on the guide rod, causing the guide block to move back and forth inside the first inner groove. This allows the guide block to drive the support block to move back and forth, facilitating the movement of the cross plate, rotary motor, electric telescopic rod, and drill bit. This facilitates the forward and backward displacement of the drilling machine, improving its flexibility and, consequently, the accuracy of drilling holes in the plate.

[0017] After the board material is fixed in place as described above, the electric telescopic rod drives the drill bit down to the desired drilling position on the board. Then, the rotary motor is started to rotate the drill bit, making it easier for the drill bit to drill holes in the board material. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-5 The present invention provides the following technical solution:

[0027] Example 1

[0028] To address the problem in existing drilling machines where forward and backward movement is inconvenient, thus affecting drilling accuracy, the following solution is disclosed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 3 The system includes a base 1 and a support block 4. A guide rod 2 is provided on one side inside the base 1, and a guide block 3 is sleeved on the outside of the guide rod 2. A servo motor 5 is connected to one side of the base 1, and a connecting rod 6 is connected to one side of the servo motor 5. A drive gear 7 is sleeved on the outside of the connecting rod 6, and a movable gear plate 8 meshes with one side of the drive gear 7. The top of both the movable gear plate 8 and the guide block 3 is provided with a support block 4. A first inner groove 101 is provided on one side of the base 1, and a second inner groove 102 is provided on the other side of the base 1.

[0029] In this embodiment, during use, the servo motor 5 is activated, causing the connecting rod 6 to rotate. The connecting rod 6 then rotates the drive gear 7, causing the drive gear 7 and the moving gear plate 8 to mesh. This causes the moving gear plate 8 to move back and forth inside the second inner groove 102. Simultaneously, the moving gear plate 8 drives the support block 4 to move back and forth, and the guide block 3 slides on the guide rod 2, allowing the guide block 3 to move back and forth inside the first inner groove 101. This movement of the guide block 3 and the support block 4 facilitates the movement of the support block 4, which in turn drives the horizontal plate 9, the rotary motor 10, the electric telescopic rod 11, and the drill bit 12. This allows the drilling machine to be displaced back and forth, enabling adjustment of the drilling position on the sheet metal. This improves the flexibility of the drilling machine and, consequently, the accuracy of drilling holes in the sheet metal.

[0030] Example 2

[0031] This embodiment differs from Embodiment 1. To address the problem in the prior art where drilling machines are inconvenient for limiting and fixing the sheet metal, leading to easy positional displacement of the sheet metal, the following solution is disclosed. Please refer to the details below. Figure 1 , Figure 4 , Figure 5 The support block 4 consists of two blocks, connected by a horizontal plate 9. An electric telescopic rod 11 is mounted on the top of the horizontal plate 9, with one end connected to a rotary motor 10 and the other end connected to a drill bit 12. Cylinders 13 are mounted on both ends of the bottom of the horizontal plate 9, with a fixing block 14 connected to the bottom of each cylinder 13. A threaded rod 15 is mounted inside the fixing block 14, and a sleeve block 16 is fitted around the threaded rod 15. A limit mechanism 17 is mounted on one side of the sleeve block 16. A limit rod is mounted inside the fixing block 14, and a sleeve block 16 is fitted around the limit rod. The sleeve block 16 has a rectangular cross-section. Two limit mechanisms 17 are provided, each including a fixed frame 1701, which is located on one side of the sleeve block 16. A pressure rod 1702 passes through the interior of one end of the fixed frame 1701, and a limit block 1704 is provided at one end of the pressure rod 1702. A handle 1703 is threaded to the other end of the pressure rod 1702. The cross-section of the fixed frame 1701 is an inverted "L" shape. A groove 1705 is provided at the top of the fixed frame 1701, and the cross-section of the groove 1705 is annular. A rubber pad is connected to one side of the fixed frame 1701. Rubber protrusions are evenly provided at the bottom of the limit block 1704.

[0032] In this embodiment, during use, the cylinder 13 drives the fixed block 14 to descend, moving the sleeve block 16 to the desired position. The threaded rod 15 is rotated outwards, causing the sleeve block 16 to move horizontally. Simultaneously, the sleeve block 16 slides on the limit rod, improving the stability of its movement. Two sets of sleeve blocks 16 are provided; the width of the plate placement position is adjusted by regulating the distance between them. When the sleeve block 16 moves to the desired position, a positioning pin can be inserted into the fixed block 14 to prevent the threaded rod 15 from rotating when it stops. The plate is then placed between the sleeve blocks 16, and clamped and fixed by the fixing frame 1701 and rubber pads to prevent displacement during drilling. The rubber pads also provide insulation at the plate clamping point. To protect the material from external damage, the handle 1703 is rotated inside the groove 1705. Since the handle 1703 and the pressure rod 1702 are connected by a thread, the handle 1703 drives the pressure rod 1702 to move downward, thereby pressing the limiting block 1704 against the material. This facilitates further clamping and fixing of the material, improving the stability of drilling and the accuracy of the drilling machine. The bottom of the limiting block 1704 is uniformly provided with rubber protrusions, which protect the material from external damage. The electric telescopic rod 11 drives the drill bit 12 to descend, so that the drill bit 12 is pressed against the material where drilling is required. The rotary motor 10 is started, which drives the drill bit 12 to rotate, facilitating the drilling of the material by the drill bit 12.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
