Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and more specifically, to a drilling device for processing metal workpieces. Background Technology

[0002] Metalworking is a process technology that transforms metal workpieces into items, parts, and components. It includes large parts such as bridges and ships, as well as small components such as engines, jewelry, and watches. Metalworking involves many steps, including drilling metal workpieces. Before drilling, the workpiece must be fixed in a fixture. After drilling, the chips and dirt on the worktable must be cleaned; otherwise, the fixture or workpiece cannot be positioned correctly, which will affect subsequent drilling operations.

[0003] Most existing drilling devices are unable to clean up the chips, which in turn affects the subsequent clamping of the metal workpiece.

[0004] A search revealed a Chinese patent with publication number CN221890928U that discloses a drilling device for metal processing. This utility model uses an exhaust pipe to blow chips into a collection box for chip collection, thereby ensuring that the surface of the slider is clean and tidy, which is beneficial for the subsequent clamping operation of the clamping mechanism on the metal workpiece. The pressure plate clamps the metal workpiece, ensuring that it will not move when drilling, which is beneficial for subsequent drilling operations.

[0005] However, in actual use, the drilling device described above leaves some residue on the surface of the metal workpiece during the drilling process. This residue will splash outwards during the drilling process, which will affect the drilling accuracy of the metal workpiece. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a drilling device for processing metal workpieces to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A drilling device for processing metal workpieces includes a worktable, a mounting arm fixedly connected to one side of the worktable, a drilling machine body mounted inside the mounting arm, a drill bit disposed at the bottom end of the drilling machine body, a fixing ring fixedly connected to one side of the mounting arm, a base column fixedly connected to the inside of the worktable, and a cleaning mechanism disposed on the outside of the worktable; the cleaning mechanism includes a liquid storage tank, one side of which is fixedly connected to the outside of the worktable, a water pump fixedly connected to the top of the liquid storage tank, and water supply terminals fixedly connected to both the output and input ends of the water pump. The system includes a water supply pipe, one end of which penetrates the inside of the storage tank and extends into the tank. A fan is fixedly connected to one side of the mounting arm, and an air duct is fixedly connected to the output end of the fan. An arc-shaped conduit is fixedly connected to one end of both the water supply pipe and the air duct. Two flexible hoses are fixedly connected to the bottom of the arc-shaped conduit, and an empty pipe is fixedly connected to the bottom of each flexible hose. One side of the empty pipe is hinged to the outside of a fixing ring, and an electric cylinder is hinged to one side of the empty pipe. One end of the electric cylinder is hinged to the outside of the drilling machine body. A switching mechanism is provided on the top of the workbench.

[0009] By adopting the above technical solution: using an electric cylinder to drive the empty tube to deflect, the empty tube can be aligned with the drill bit and the drilling position of the metal workpiece to spray coolant, and the two empty tubes can be combined to blow and clean the coolant and residue on the surface of the metal workpiece, avoiding the splashing of residue from the drilling hole of the metal workpiece.

[0010] As a further description of the above technical solution: the switching mechanism includes a chassis, the bottom end of which is rotatably connected to the inner side of a base column. Multiple openings are provided on the inner side of the chassis. Two fixed frames are fixedly connected inside the chassis. A rotating rod is rotatably connected to the inner side of each fixed frame. Two threads are symmetrically arranged on the outer side of the rotating rod. Two clamping arms are slidably connected to the inner side of each fixed frame. Two pressure blocks are fixedly connected to the bottom of each clamping arm. A fixed rod is fixedly connected to one side of the base column. A pin is inserted into the inner side of the fixed rod, and one end of the pin is inserted into the inner side of the chassis.

[0011] By adopting the above technical solution: through the screw drive of the rotating rod and the thread, the two clamping arms and the pressure block are positioned to position the metal workpiece, and in conjunction with the rotation of the chassis, the two metal workpieces can be interchanged, thus separating the loading / unloading area and the processing area.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a cleaning mechanism, compared with the existing technology, multiple deflectable tubes are used to spray coolant and blow air respectively, which can effectively prevent drilling residue from splashing out, and can flush out fine chips from the hole and the chip groove of the drill bit, preventing chips from accumulating on the workpiece surface, keeping the processing area and the surface of the metal workpiece clean, improving the service life of the drill bit, and improving the drilling accuracy of the metal workpiece.

[0014] 2. By setting up a switching mechanism, compared with the existing technology, the positions of two metal workpieces are switched by rotating the chassis and the fixed frame, realizing the physical separation of the processing area and the loading and unloading area, eliminating the idle time of the equipment waiting for loading and unloading, and improving production efficiency.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The embodiments disclosed in this application are as follows: Figures 1-6The diagram shows a drilling device for processing metal workpieces, comprising a worktable 1, a mounting arm 2 fixedly connected to one side of the worktable 1, a drilling machine body 3 mounted inside the mounting arm 2, a drill bit 4 at the bottom of the drilling machine body 3, a fixing ring 6 fixedly connected to one side of the mounting arm 2, a base column 5 fixedly connected to the inside of the worktable 1, and a cleaning mechanism on the outside of the worktable 1. The cleaning mechanism includes a liquid storage tank 7, one side of which is fixedly connected to the outside of the worktable 1, a water pump 8 fixedly connected to the top of the liquid storage tank 7, and water pipes 9 fixedly connected to both the output and input ends of the water pump 8. One end of one of the water pipes 9 penetrates the inside of the liquid storage tank 7 and extends into the interior of the liquid storage tank 7. A fan 10 is fixedly connected to one side of the mounting arm 2, and an air duct 11 is fixedly connected to the output end of the fan 10. An arc-shaped conduit 12 is fixedly connected to one end of a water pipe 9 and an air pipe 11. Two flexible hoses 13 are fixedly connected to the bottom of the arc-shaped conduit 12. An empty pipe 14 is fixedly connected to the bottom of the flexible hoses 13. One side of the empty pipe 14 is hinged to the outside of the fixing ring 6. An electric cylinder 15 is hinged to one side of the empty pipe 14. One end of the electric cylinder 15 is hinged to the outside of the drilling machine body 3. A switching mechanism is set on the top of the workbench 1. Coolant and air are input into the two arc-shaped conduits 12 by the water pump 8, water pipe 9, fan 10 and air pipe 11. Combined with the electric cylinder 15 pushing the empty pipe 14 to deflect, the coolant can first spray and cool the drilling position of the drill bit 4 and the metal workpiece. At the same time, the air blows the coolant and residue outward, improving the drilling accuracy and cleaning efficiency of the metal workpiece.

[0024] Reference Figure 1 , Figure 3 and Figure 4 As shown, the switching mechanism includes a chassis 16, the bottom of which is rotatably connected to the inner side of the base column 5. Multiple openings 17 are provided on the inner side of the chassis 16. Two fixing brackets 18 are fixedly connected inside the chassis 16. A rotating rod 19 is rotatably connected to the inner side of each fixing bracket 18. Two threads 20 are symmetrically arranged on the outer side of the rotating rod 19. Two clamping arms 21 are slidably connected to the inner side of each fixing bracket 18. Two pressure blocks 22 are fixedly connected to the bottom of each clamping arm 21. A fixing rod 23 is fixedly connected to one side of the base column 5. A pin 24 is inserted into the inner side of the base 16. One end of the pin 24 is inserted into the inner side of the base 16. By rotating the rotating rod 19 and the thread 20, the two clamping arms 21 and the pressure block 22 are positioned opposite each other for the metal workpiece. The positioning of the base 16 by the pin 24 allows the base 16 to rotate on the top of the base column 5. The base 16 can drive the two fixed frames 18 and the metal workpiece to deflect and change positions. Unprocessed metal workpieces can be pre-positioned and installed, improving the continuity of the loading and unloading of metal workpieces and the coordination of the drilling equipment.

[0025] The working principle of this utility model is as follows: When drilling a metal workpiece, the workpiece is first placed on the upper surface of the fixing frame 18 at the top of the chassis 16. Then, the rotating rod 19 is rotated inside the fixing frame 18, causing the two symmetrically arranged threads 20 on the outer side of the rotating rod 19 to drive the two clamping arms 21. This allows the two clamping arms 21 to drive the corresponding two pressure blocks 22 to press and position the metal workpiece placed on the upper surface of the fixing frame 18. Then, the pin 24 is pulled out from one side of the chassis 16, which pushes the chassis 16, allowing it to rotate on the top of the base column 5. After the chassis 16 rotates 180 degrees, the pin 24 can be reinserted into the chassis 16. Then, another metal workpiece is placed on the upper surface of the fixing frame 18 on the other side. The drilling machine body 3 is started, driving the drill bit 4 to drill a hole in the surface of the metal workpiece. At the same time, the water pump 8 and the water supply pipe 9 are started to input the coolant injected into the liquid storage tank 7 into the connected arc-shaped conduit 12 and two hoses 13. Then, the coolant is output through the corresponding two empty pipes 14 to the drilling position of the drill bit 4 and the metal workpiece to rinse the residue and reduce the temperature. After that, the fan 10, the air pipe 11, and the arc-shaped conduit 12 input fresh air into the two hoses 13 and the empty pipes 14, so that the air blows from the bottom of the two empty pipes 14 to the drilling position of the drill bit 4 and the metal workpiece, which can promote the removal of coolant and residue from the surface of the metal workpiece. The blown-off residue and coolant fall into the interior of the chassis 16, and the coolant and residue are filtered and separated through multiple openings 17 to complete the drilling of the metal workpiece.
