Description

Technical Field

[0001] This utility model belongs to the field of bench drill technology, and in particular relates to an integrated lightweight bench drill that can be used for both drilling and tapping. Background Technology

[0002] A bench drill, also known as a benchtop drill, is a small drilling machine that can be placed on a worktable with a vertically arranged spindle. Benchtop drills typically drill holes with a diameter of 13 mm or less, generally not exceeding 25 mm. Spindle speed is usually changed by altering the position of the V-belt on the pulley, and spindle feed is manually operated.

[0003] Patent CN219358643U discloses a multifunctional integrated drilling and tapping bench drill, belonging to the field of bench drill technology. It includes a bench drill base, with a lifting device fixedly installed on one side of the top of the base. A driver is fixedly installed on the top of the lifting device, and an upper chuck seat is provided on the other side of the bottom of the driver. In this invention, the upper drive shaft, during its upward movement with the driver, utilizes the linkage between the driving gear plate, the driving large gear, the driven large gear, and the driven small gear. This, in turn, drives the driven gear plate to accelerate through the driven small gear, allowing the tapping head to perform tapping during the drill bit's upward resetting process. This effectively improves the bench drill's processing efficiency. Because the friction during drilling is high, generating significant heat, performing tapping shortly after drilling reduces the impact of stress changes in the hole's cooling, thus reducing wear on the tapping head.

[0004] In the existing technology, the processing efficiency is improved by setting the linkage between the driving gear and the driven gear, but the following problems still exist in the overall use: First, the positioning of the workpiece requires additional tooling fixtures, the installation and assembly operation is cumbersome, and the existing equipment is huge and bulky, making it inconvenient to carry and move; Second, the existing device cannot collect the debris when processing the workpiece, causing the debris to adhere to the surface of the workpiece and affecting the processing quality.

The moving block 38 is threadedly connected to the first threaded rod 11. An auxiliary rod is mounted on one side of the first threaded rod 11. The auxiliary rod cooperates with the first threaded rod 11 to drive the moving platform 13 to move. A handle 12 is rotatably mounted on the outside of the base 10. A drive shaft is mounted on one end of the handle 12. The drive shaft is rotatably connected to the inner wall of the base 10. A second pulley is mounted on one end of the drive shaft. The first pulley and the second pulley are connected by a belt drive, so that the first threaded rod 11 and the handle 12 are connected by a belt drive.

[0037] Further reference Figure 3 and Figure 4The end face of the moving platform 13 is provided with a sliding groove 15, and a sliding sleeve 18 is slidably arranged inside the sliding groove 15. One end of the sliding sleeve 18 is fixedly connected to the bottom end face of the positioning block 14. A second threaded rod 17 is rotatably arranged on the bottom end face of the moving platform 13. The second threaded rod 17 is threadedly connected to the sliding sleeve 18. A knob 16 is provided at one end of the second threaded rod 17. The second threaded rod 17 can be driven to rotate by rotating the knob 16. Multiple folding blocks for auxiliary positioning are provided on the end face of the moving platform 13, so that the workpiece can abut against one side of the folding block to form a clamping effect with the sliding positioning block 14.

[0038] Further reference Figure 1 and 2 A slide rail 27 is provided on the end face of the mounting plate 26, and a slider 28 is slidably provided on the outside of the slide rail 27. The slider 28 is fixedly connected to the lifting block 30. Connectors 39 are provided on both sides of the slider 28, and return springs 29 are provided on the end faces of the two connectors 39. A protrusion is provided on the end face of the mounting plate 26, and one end of the return spring 29 is fixedly connected to the protrusion. By setting the return spring 29, the lifting block 30 can be provided with a rebound force. After use, it will pull the lifting block 30 to reset, thus facilitating the next use and improving the convenience of the device.

[0039] Further reference Figure 1 and Figure 2 The lifting block 30 is equipped with a drive motor 31 inside. A gearbox 32 is provided on the bottom end face of the lifting block 30. The torque during drilling or tapping can be adjusted by setting the gearbox 32, thereby improving the overall flexibility of the device. The output shaft of the drive motor 31 is connected to the gearbox 32. A chuck 33 is provided at the bottom of the gearbox 32. The chuck 33 is used to hold the drill bit and the tap, thereby facilitating the switching of the device's functions and improving the device's flexibility. A support rod is provided on one side of the lifting block 30. A controller 41 is provided at the top end of the support rod. A switch button is provided on the end face of the controller 41.

[0040] Further reference Figure 6 and Figure 7 The lifting block 30 has a limiting groove 34 on its outside. A transmission rod 35 is slidably installed inside the limiting groove 34. A connecting rod 36 is installed at one end of the transmission rod 35. The connecting rod 36 is rotatably connected to a handle 37. One end of the handle 37 is rotatably connected to a mounting plate 26. By setting the handle 37, the lifting block 30 can be moved up and down by rotating the handle 37, thereby driving the drill bit at the bottom of the lifting block 30 to process the workpiece. The limiting groove 34 allows the transmission rod 35 at the bottom end to slide adaptively within the limiting groove 34 when the connecting rod 36 moves. One end of the transmission rod 35 is provided with a wide head, which prevents the transmission rod 35 from dislodging from the inside of the limiting groove 34, thereby improving the overall adaptability of the device.

[0041] Furthermore, two miniature fans 24 are symmetrically arranged below the mobile platform 13. A cooling block 25 is positioned above the two miniature fans 24 on the end face of the mobile platform 13. The cooling block 25 is connected to the air outlet of the miniature fans 24. A cooling chamber 26 is provided inside the cooling block 25. The two cooling chambers 26 are symmetrically arranged and are L-shaped, with their air outlets pointing towards the drill bit processing area. The air generated by the miniature fans 24 when they absorb waste chips through the trough 43 can be ejected from the cooling chamber 42, thereby reducing the temperature of the drill bit. The temperature treatment also cleans the surface of the workpiece, preventing waste from adhering to the workpiece surface. Filter screens 23 are provided on both sides of the collection box 22. The two filter screens 23 are respectively abutted against the air inlet of the micro fan 24. Through this setting, the air in the collection box 22 can be drawn out, so that the collection box 22 generates negative pressure. The debris on the end face of the moving platform 13 is adsorbed through the trough 43. By setting the filter screens 23, the waste can be prevented from entering the micro fan 24, preventing damage to the micro fan 24, thereby improving the service life of the device.

[0042] In use, the workpiece is placed on the end face of the moving platform 13, and then the knob 16 at one end of the second threaded rod 17 is rotated, causing the second threaded rod 17 to rotate and drive the moving sleeve 18 to move. The moving sleeve 18 moves along the slide groove 15 and drives the top positioning block 14 to move, so that the positioning block 14 pushes the top workpiece to move and abuts the workpiece against one side of the folding block to position the workpiece. Then, by fixing the drill bit or tap to the bottom of the chuck 33, the mounting block 21 is fitted onto the outer circular surface of the vertical shaft 19. The height of the mounting block 21 is observed through the scale 20, which is equivalent to controlling the height of the drill bit. Then, the fixing knob is rotated to fix the mounting block 21, thus fixing the height of the mounting plate 26. Then, the drive motor 31 is started by the switch button on the controller 41, so that the drive shaft of the drive motor 31 drives the drill bit to rotate.

[0043] During processing, rotating the handle 37 causes the connecting rod 36 on one side to move downwards, which in turn causes the transmission rod 35 to move downwards. The transmission rod 35 slides adaptively inside the limiting groove 34 and pushes the drive motor 31 downwards, allowing the drill bit at the bottom of the drive motor 31 to process the workpiece. At the same time, the micro fan 24 is activated, causing the micro fan 24 to discharge the air inside the collection box 22 through the cooling chamber 42 to cool the surface of the drill bit. Simultaneously, a negative pressure is formed inside the collection box 22, which adsorbs the waste debris on the end face of the moving platform 13 through the trough 43, thereby collecting the waste debris. After collection, the moving platform 13 and the collection box 22 are removed for cleaning.
