Description

Technical Field

[0001] This utility model relates to the field of sheet metal drilling technology, and in particular to a drilling device. Background Technology

[0002] In sheet metal processing, drilling is a crucial step in achieving structural assembly and fastening connections. For example, drilling is used to install screws, bolts, or other fasteners to ensure a secure and reliable connection between components. Sheet metal requires three different types of holes for various purposes: screw holes for fixing, pre-drilled holes as required by the customer, and through holes for wiring. These holes not only facilitate subsequent installation and fixing but also improve the overall structural stability.

[0003] In existing technologies, traditional drilling equipment mostly uses a single-direction clamping mechanism, which cannot effectively control the multi-dimensional displacement of the plate during the drilling process. When the drill bit contacts the plate, the resulting cutting force can easily cause the plate to shift horizontally or vibrate vertically, seriously affecting the drilling accuracy. Therefore, we propose a drilling device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drilling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drilling device includes a frame. Two servo motors are fixedly connected to the outer wall of the frame. Lead screws are fixedly connected to the outer walls of the output shafts of the two servo motors. Four guide rods are fixedly connected to the outer wall of the frame. The four guide rods are slidably fitted onto a mounting frame and a worktable in pairs. A threaded hole is opened at the bottom of the worktable. The inner wall of the threaded hole is threadedly connected to the outer wall of one of the lead screws. An electric push rod is fixedly connected to the outer wall of the mounting frame. A drilling machine body is fixedly connected to the bottom of the output end of the electric push rod. A return frame is fixedly fitted onto the outer wall of the drilling machine body. Two rectangular grooves are opened at the bottom of the return frame. Short shafts are fixedly connected to the inner walls of the two rectangular grooves. Legs are rotatably fitted onto the outer walls of the two short shafts. U-shaped sleeves are fixedly connected to the outer walls of the two legs. Metal elastic plates are placed inside the two U-shaped sleeves. The tops of the two metal elastic plates are fixedly connected to the outer wall of the mounting frame. A pressing component is provided at the bottom of the legs.

[0007] Preferably, the pressing assembly includes two threaded mating sleeves, the bottoms of the two legs are fixedly connected to the outer walls of the two threaded mating sleeves respectively, a first pressing roller is rotatably connected to one end of each of the two threaded mating sleeves, a threaded rod is threadedly connected to the inner wall of each of the two threaded mating sleeves, and a second pressing roller is rotatably connected to one end of each of the two threaded rods. The pressing assembly is used to fix the position of the plate.

[0008] Preferably, the outer wall of the frame has two through holes, and the inner walls of the two through holes are rotatably connected to the outer walls of two lead screws, so that the worktable and the mounting frame can be moved by the lead screws.

[0009] Preferably, one end of each of the two lead screws is fixedly fitted with a roller bearing, and the outer ring of the roller bearing is fixedly connected to the outer wall of the frame. The roller bearing is used to assist the lead screw in stable rotation.

[0010] Preferably, the top of the mounting bracket is provided with a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the output end of the electric push rod, so that the mounting bracket can be moved up and down by setting the electric push rod.

[0011] Preferably, the outer walls of both threaded rods are threaded with nuts. Rotating the nuts presses against the outer wall of the threaded mating sleeve, preventing the threaded rods from rotating through the second lower pressure roller. The thread directions of the threaded rods and nuts are opposite, and a washer can be added.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] In this solution, the worktable is longitudinally positioned by a servo motor-driven lead screw, while the mounting frame is laterally moved by another set of servo motors and lead screws. An electric push rod drives the drilling machine body for vertical feed. During drilling, the lowering assembly descends synchronously with the drill bit. The inclined legs, when the first and second lowering rollers contact the sheet metal, generate an outward-expanding clamping force through the elastic deformation of the metal elastic sheet, achieving automatic clamping of the sheet metal. This design can accommodate processing sheet metal of varying widths. Attached Figure Description

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

[0021] Depend on Figures 1-4 As shown, a drilling device is disclosed, comprising a frame 1. Two servo motors 2 are fixedly connected to the outer wall of the frame 1. Lead screws 3 are fixedly connected to the outer walls of the output shafts of the two servo motors 2. Two through holes are opened on the outer wall of the frame 1. The inner walls of the two through holes are rotatably connected to the outer walls of the two lead screws 3 respectively. Roller bearings are fixedly fitted at one end of the two lead screws 3. The outer rings of the roller bearings are fixedly connected to the outer wall of the frame 1. The lead screws 3 are rotatably connected to the through holes of the frame 1 through the roller bearings to ensure smooth transmission.

[0022] Four guide rods 4 are fixedly connected to the outer wall of the frame 1. The four guide rods 4 are slidably mounted on the mounting frame 5 and the worktable 8 in pairs. The four guide rods 4 form a double track guide, which improves the movement stability of the worktable 8 and the mounting frame 5. The bottom of the worktable 8 is provided with a threaded hole. The inner wall of the threaded hole is threadedly connected to the outer wall of one of the lead screws 3. An electric push rod 6 is fixedly connected to the outer wall of the mounting frame 5. A sliding hole is provided on the top of the mounting frame 5. The inner wall of the sliding hole is slidably connected to the outer wall of the output end of the electric push rod 6.

[0023] The bottom of the output end of the electric push rod 6 is fixedly connected to the drilling machine body 7 (Z1Z). The electric push rod 6 realizes the vertical feed movement of the drilling machine body 7 (Z1Z). The outer wall of the drilling machine body 7 (Z1Z) is fixedly fitted with a return frame. The bottom of the return frame has two rectangular grooves. The inner wall of the two rectangular grooves is fixedly connected to a short shaft 9. The foot 10 is hinged to the return frame through the short shaft 9.

[0024] Both short shafts 9 are rotatably fitted with legs 10 on their outer walls. Both legs 10 are fixedly connected to U-shaped sleeves 12 on their outer walls. Both U-shaped sleeves 12 contain metal elastic plates 11. The tops of both metal elastic plates 11 are fixedly connected to the outer wall of the mounting bracket 5 by existing bolts. When disassembling, the bolts are rotated and the bottom of the metal elastic plate 11 is removed from the U-shaped sleeve 12. The metal elastic plate 11 provides elastic restoring force, so that the legs 10 automatically return to their original position after moving on the drilling machine body 7 (Z1Z).

[0025] The bottom of the leg 10 is provided with a pressing assembly, which includes two threaded mating sleeves 13. The bottom of the two legs 10 is fixedly connected to the outer wall of the two threaded mating sleeves 13 respectively. One end of each of the two threaded mating sleeves 13 is rotatably connected to a first pressing roller 14 through an existing bearing. The inner wall of each of the two threaded mating sleeves 13 is threaded with a threaded rod 15. The outer wall of each of the two threaded rods 15 is threaded with a nut. One end of each of the two threaded rods 15 is rotatably connected to a second pressing roller 16 through an existing bearing.

[0026] Working principle: During use, the sheet material is placed on the worktable 8. One of the servo motors 2 rotates, driving the connected lead screw 3 to rotate. The rotation of the lead screw 3 moves the worktable 8, thus positioning the sheet material below the drilling machine body 7. Simultaneously, the other servo motor 2 rotates, driving the connected lead screw 3 to rotate. The rotation of the lead screw 3 causes the mounting bracket 5 to move laterally, adjusting the lateral position of the drilling machine body 7. The electric push rod 6 then moves the drilling machine body 7 up and down. When the drilling machine body 7 moves downward to drill, it causes the two legs 10 to move downward, which in turn causes the two threaded coupling sleeves 13 to move downward. The two threaded coupling sleeves 13 move downwards, causing the first lower pressure roller 14 and the second lower pressure roller 16 to move downwards. After the first lower pressure roller 14 and the second lower pressure roller 16 press against the top of the plate, the two metal elastic plates 11 undergo elastic deformation due to the inclined setting of the first lower pressure roller 14 and the second lower pressure roller 16. The first lower pressure roller 14 and the second lower pressure roller 16 move outwards, pressing and limiting the plate to prevent it from moving during drilling. When limiting the plate of different widths, the two threaded rods 15 are rotated to adjust the position of the second lower pressure roller 16, so that the distance between the first lower pressure roller 14 and the second lower pressure roller 16 changes, thus satisfying the limitation of the plate of different widths.

[0027] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the servo motor 2, the electric push rod 6, and the drilling machine body 7 to facilitate the control of the overall operation.
