Description

Technical Field

[0001] This utility model belongs to the technical field of drilling equipment, and in particular relates to a drilling machine for machining that is easy to automatically position. Background Technology

[0002] A drilling machine is a machine tool that mainly uses a drill bit to process holes in a workpiece. Usually, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. Drilling machines have a simple structure and relatively low machining accuracy. They can drill through holes and blind holes. By changing special tools, they can also perform processes such as reaming, counterboring, boring, or tapping.

[0003] Patent CN221362826U discloses a drilling machine for machining that facilitates automatic positioning. The machine includes a base plate with a hollowed-out top and grooves running through both sides. A support platform is fixed to the grooves via a slide rail. A rack is bolted to the bottom of the support platform, and the rack meshes with a gear. A lead screw is rotatably connected to one side of the support platform via a bearing. The lead screw is rotatably connected to a worktable via a lead screw structure. The advantages are: by setting up a displacement structure composed of a lead screw, support platform, rack, gear, and sliding rod, this invention allows for precise movement of parts to the desired position on the control panel, improving positioning accuracy and thus enhancing the quality of the machined parts.

[0004] In existing technologies, by setting up structures such as lead screws and support platforms, parts can be positioned and positioning accuracy can be improved. However, the following problems still exist in overall use: First, when processing workpieces, the bottom of the workpiece will be unbalanced due to its own shape. During drilling, the pressure and vibration of the drill bit will cause it to tilt, affecting the processing quality. Moreover, existing technologies cannot detect the horizontal height of the workpiece, resulting in deviations during drilling. Second, existing technologies lack a structure for cleaning and collecting waste chips when drilling workpieces. Dust and debris will adhere to the surface of the workpiece, affecting the accuracy and quality of drilling. Utility Model Content

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] refer to Figure 1 , Figure 2 and Figure 6 A drilling machine for machining, which facilitates automatic positioning, includes a machine body 10 and a drilling device 38. The drilling device 38 is located on one side of the machine body 10. The drilling device 38 is entirely based on existing technology and is not an innovation of this invention. The drilling device 38 only needs to perform the drilling operation on the workpiece. Therefore, the electrical control method and specific structure of the drilling device 38 (signal transmission, electrical connection between various sensors) will not be elaborated in this solution. A positioning box 11 is slidably arranged inside the machine body 10, and the end face of the positioning box 11 slides down. The device is equipped with a liftable lifting plate 12, and multiple strip-shaped slots are provided on the end face of the lifting plate 12. This design can prevent the drill bit of the drilling device 38 from being damaged by the lifting error of the lifting plate 12, thereby improving the service life of the device. A mounting base 21 is provided on the end face of the positioning box 11. Two detection mounting shells 20 are rotatably provided on the end face of the mounting base 21. Detection probes 25 for detecting levelness are slidably provided inside the two detection mounting shells 20. A dust suction port 32 for collecting waste is provided on the bottom end face of the positioning box 11.

[0027] Further reference Figure 1 and Figure 3A fixing plate 45 is provided on the end face of the positioning box 11. A first cylinder is provided on one side of the fixing plate 45. A clamping block 44 is provided at the end of the first cylinder output shaft facing the mounting base 21. By activating the fixing plate 45, the clamping block 44 at one end can be pushed to move towards the mounting base 21 and clamp the workpiece between the clamping block 44 and the mounting base 21, thereby improving the stability of the workpiece during drilling. Multiple auxiliary telescopic rods are provided between the clamping block 44 and the fixing plate 45 to limit the movement direction of the clamping block 44, prevent the clamping block 44 from rotating and damaging the internal transmission structure of the fixing plate 45, thereby improving the service life of the fixing plate 45.

[0028] Further reference Figure 2 , Figure 3 and Figure 4 A knob 13 is rotatably mounted on the end face of the positioning box 11. A threaded rod 14 is rotatably mounted inside the positioning box 11 on the bottom end face of the knob 13. A U-shaped plate 46 is mounted on the inner wall of the positioning box 11. The threaded rod 14 is rotatably connected to the U-shaped plate 46, which supports the threaded rod 14 and improves its stability. A threaded sleeve 15 is slidably mounted on the outside of the threaded rod 14. The threaded sleeve 15 is threadedly connected to the threaded rod 14. A long rod is mounted on one side of the threaded sleeve 15. A top rod 16 is mounted on the top end face of the long rod. One top end of the top rod 16 is fixedly connected to the bottom end face of the lifting plate 12. A limit rod 17 is mounted on the bottom end face of the lifting plate 12. One end of the limit rod 17 is equipped with a... The connecting rod 18 has an auxiliary rod 19 slidably mounted inside it. One end of the auxiliary rod 19 is fixedly connected to the inner wall of the positioning box 11, and the other end is fixedly connected to the end face of the U-shaped plate 46. By setting the auxiliary rod 19, the movement direction of the lifting plate 12 can be restricted to prevent the lifting plate 12 from rotating. When positioning the workpiece, if the bottom end face of the workpiece is not supported enough, the threaded rod 14 can be rotated by rotating the knob 13. After the threaded rod 14 rotates, it drives the external threaded sleeve 15 to rise through the thread. The threaded sleeve 15 pushes the lifting plate 12 to rise through the push rod 16 on one side, thereby causing the lifting plate 12 to push the bottom end face of the workpiece to move upward, thereby supporting the workpiece and adjusting the level of the workpiece.

[0029] Further reference Figure 3 The bottom end face of the lifting plate 12 is provided with a guard plate 43. After the lifting plate 12 is lifted, a storage groove for the lifting plate 12 will appear on the end face of the positioning box 11. By providing the guard plate 43, the guard plate 43 can be moved upward when the lifting plate 12 moves, and the guard plate 43 will abut against the inner wall of the storage groove of the positioning box 11, preventing the debris generated during processing from entering the interior of the positioning box 11 through the storage groove and damaging the transmission components, thereby improving the service life of the device.

[0030] Further reference Figure 2 , Figure 5 and Figure 6 Both detection mounting shells 20 are equipped with elastic telescopic members 24 inside. One end of each elastic telescopic member 24 is fixedly connected to the top end face of the detection probe 25. Both detection probes 25 are equipped with fixing members 26 on their outer circular surfaces. The outer surface of the detection mounting shell 20 is provided with a limiting groove 27. The limiting groove 27 is L-shaped. The fixing member 26 is slidably connected to the limiting groove 27. By setting the limiting groove 27, after the fixing member 26 is detected, the fixing member 26 can be rotated to abut against the transverse groove of the limiting groove 27 to prevent the fixing member 26 from sliding out and to store the fixing member 26. A height gauge 29 is set on one side of the limiting groove 27 on the outer surface of the detection mounting shell 20. The height gauge 29 makes it easy to observe the height of the two limiting grooves 27, thereby facilitating the adjustment of the lifting height of the lifting plate 12 to adjust the level of the workpiece and improving the convenience of the device.

[0031] Both detection mounting shells 20 have rotating shafts 28 rotatably mounted on their bottom end faces. Both shafts 28 are fixedly connected to the end faces of mounting bases 21. Both mounting bases 21 have positioning grooves 22 on their end faces. Positioning rods 23 are slidably mounted inside the positioning grooves 22. The two positioning rods 23 are fixedly connected to the bottom end faces of the two detection mounting shells 20 respectively. By setting the positioning grooves 22 and the positioning rods 23, the position of the detection mounting shells 20 can be restricted and guided, thereby supporting the detection mounting shells 20 and improving their stability.

[0032] Further reference Figure 2 , Figure 3 and Figure 4 The positioning box 11 is equipped with a blower 30. The air inlet of the blower 30 is connected to the dust suction port 32 through a hose. The air outlet of the blower 30 is equipped with a collection box 31. The collection box 31 is connected to the blower 30 through a pipe. The bottom end face of the positioning box 11 is equipped with an expansion groove 33. With this setting, when the positioning box 11 moves, the blower 30 is started to perform dust suction treatment on the inside of the machine body 10. The metal debris generated by drilling is absorbed into the collection box 31 through the dust suction port 32 for recycling. The expansion groove 33 can create a gap between the positioning box 11 and the bottom of the inner wall of the machine body 10, which facilitates the suction of metal waste and improves cleaning efficiency.

[0033] A filter plate 34 is provided on the top end face of the collection box 31, and a diversion pipe 35 is provided on the end face of the filter plate 34. The diversion pipe 35 is connected to two detection mounting shells 20 through air pipes. Both detection mounting shells 20 have cavities inside, and a connection port 36 is provided on one side of the two cavities on the outer surface of the detection mounting shells 20. The diversion pipe 35 is connected to the connection port 36. A cleaning hole 37 is provided on the bottom end face of the two detection mounting shells 20. The blower 30 transmits the adsorbed waste to the inside of the collection box 31. The drawn air enters the inside of the diversion pipe 35 through the filter plate 34. The filter plate 34 filters the air to prevent metal waste from entering the inside of the detection mounting shells 20. The air entering the inside of the detection mounting shells 20 is sprayed out from the bottom of the cleaning hole 37, which can blow air to clean the upper surface of the workpiece when it is being inspected, preventing debris from adhering to the top of the upper surface of the workpiece, thereby improving the drilling quality.

[0034] Further reference Figure 1 and Figure 4 The outer surface of the positioning box 11 is provided with a first slide groove 39. A first slider 40 is slidably disposed inside the first slide groove 39. The first slider 40 is generally I-shaped and is engaged inside the first slide groove 39. A second cylinder is provided on one side of the first slider 40 on the outer surface of the body 10. The output shaft of the second cylinder is fixedly connected to the first slider 40. When the second cylinder is activated, it can push the first slider 40 to move, and the positioning box 11 is moved through the first slider 40. A second slide groove 41 is provided on one side of the first slide groove 39 on the outer surface of the positioning box 11. A second slider 42 is slidably disposed inside the second slide groove 41. A third cylinder is provided on one side of the second slider 42 on the outer surface of the body 10. The output shaft of the third cylinder is connected to the second slider 42. The fixed connection allows the third cylinder to be activated, which in turn pushes the second slider 42 to move. The second slider 42 then moves the positioning box 11. When the positioning box 11 moves, the first slider 40 moves along the first slide groove 39, thereby changing the position of the positioning box 11 and facilitating automatic adjustment of the drilling position. A control terminal is provided on one side of the machine body 10 to improve the convenience of the device. In this solution, the control terminal can detect and control the specific distance of multiple first cylinders, second cylinders, and third cylinders, as well as each part, during movement. In actual production, controllers, sensors, or control circuits are installed outside these driving components. Existing technologies can be used, which are not technical problems that this solution needs to solve. Therefore, this solution will not elaborate further.
