[0030] Reference Figure 2 and Figure 3The utility model provides an embodiment: a polishing device for producing a shield machine cutter head, comprising a workbench 1, a limiting groove 25 is provided inside the workbench 1, a dual-axis motor 24 is fixedly connected inside the limiting groove 25, two output ends of the dual-axis motor 24 are fixedly connected with a fixing rod 26, and two bevel gears 23 are fixedly connected to the outside of the fixing rod 26, limiting grooves 19 are provided on both sides of the inside of the workbench 1, a bevel gear 22 is rotatably connected inside the limiting groove 19, a bidirectional screw rod 18 is fixedly connected to the outside of the bevel gear 12, and two threaded sleeves 20 are externally threadedly connected to the two threaded sleeves 20, a connecting column 21 is fixedly connected to the top of the two threaded sleeves 20, a clamping plate 16 is fixedly connected to the top of the workbench 1, an electric guide rail 12 is installed inside the bracket 2, a cylinder 13 is fixedly connected to the outside of the electric guide rail 12, a polishing disc 14 is fixedly connected to the output end of the cylinder 13, and a cleaning component is installed on the top of the bracket 2.
[0031] Specifically, the workbench 1 is the main supporting platform of the entire device, and a limit groove 19 and a limit groove 25 are arranged inside it for installing and positioning other components. The output end of the dual-axis motor 24 is connected to the fixed rod 26, and two bevel gears 23 are installed on the fixed rod 26 for transmitting and controlling the movement of other components. At the same time, the bevel gear 12 meshing with the bevel gear 23 drives the bidirectional screw 18 to rotate through the limit groove 19. The rotation of the bidirectional screw 18 can control the movement of the threaded sleeve 20. The clamping plate 16 is fixed on the threaded sleeve 20. Through the movement of the clamping plate 16, the fixed tool 17 can realize the polishing operation. The electric guide rail 12 is installed on the bracket 2 for controlling the movement of the polishing disk 14. At the same time, the output end of the cylinder 13 is connected to the polishing disk 14, and the multi-directional polishing of the tool 17 is realized through the movement of the cylinder 13.
[0032] Reference Figure 1 and Figure 4 The cleaning component includes a conveying box 4, the bottom of which is fixedly connected to the top of the bracket 2, a movable plate 27 is slidably connected inside the conveying box 4, a connecting rod 6 is fixedly connected to one side of the movable plate 27, one end of the connecting rod 6 is rotatably connected to a swing rod 7, a conveying pipe 3 is fixedly connected to the external through hole of the conveying box 4, a one-way valve 28 is installed inside the conveying pipe 3, one end of the conveying pipe 3 is fixedly connected to a connecting plate 10, and a plurality of exhaust holes 15 are fixedly connected to the outside of the connecting plate 10, a servo motor 9 is fixedly connected to the top of the bracket 2, a reciprocating wheel 8 is fixedly connected to the output end of the servo motor 9, and a swing rod 7 is rotatably connected to the outside of the reciprocating wheel 8.
[0033] Specifically, the bottom of the conveying box 4 is fixed to the top of the bracket 2, providing a closed environment for the movement of the moving plate 27. The moving plate 27 is slidably connected inside the conveying box 4 and is driven to move by the connecting rod 6 and the swing rod 7. The movement of the moving plate 27 inside the conveying box 4 helps to generate airflow and guide the gas to flow to the connecting plate 10 through the conveying pipe 3. At the same time, under the combination of the connecting rod 6 and the swing rod 7, the moving plate 27 is driven by the reciprocating wheel 8 to slide inside the conveying box 4. The connecting plate 10 is provided with an exhaust hole 15, so that the airflow is discharged from the exhaust hole 15, and then the powder on the tool 17 is cleaned to ensure that the tool 17 is clean. The servo motor 9 is started to provide power to the reciprocating wheel 8, drive the swing rod 7 to move, thereby driving the connecting rod 6 to move. This movement can effectively allow the airflow inside the conveying box 4 to clean the powder attached to the surface of the cutter head through the connecting pipe 5, wherein the conveying pipe 3 is connected to the conveying box 4, and a one-way valve 28 is installed inside to control the flow direction of the airflow. When the movable plate 27 moves to the left, the one-way valve 28 opens, allowing the airflow to flow to the conveying pipe 3; when the movable plate 27 moves to the right, the one-way valve 28 closes, stopping the airflow from flowing to the conveying pipe 3. When the air enters and exits the connecting pipe 5, it ensures that external air enters the conveying box 4 to help clean the powder on the surface of the tool 17.
[0034] Reference Figure 3 The outsides of the two bevel gears 23 are respectively meshed with the outsides of the bevel gears 1 22 at the corresponding positions. One end of the bidirectional screw rod 18 is rotatably connected to the inside of the limiting groove 19. The outside of the threaded sleeve 20 is slidably connected to the inside of the limiting groove 19. A tool 17 is arranged between the two clamping plates 16, and a rubber pad is arranged on the outside of the clamping plate 16.
[0035] Specifically, through the meshing connection between bevel gear 2 23 and bevel gear 1 22, the bidirectional screw 18 rotates at a constant speed, which in turn drives the threaded sleeve 20 to move, thereby causing the two clamping plates 16 to move relative to each other. This process achieves the clamping and fixing of the tool 17. Through the design of the anti-slip pad, the tool 17 will not be misplaced during clamping.
[0036] Reference Figure 1 One end of the swing rod 7 is rotatably connected to the connecting rod 6, the outside of the connecting rod 6 is slidably connected to one side of the conveying box 4, the top of the conveying box 4 is fixedly connected to the connecting pipe 5, and a one-way valve 29 is installed inside the connecting pipe 5. The bottom of the workbench 1 is fixedly connected with supporting legs 11 all around, and the bottom ends of the supporting legs 11 are fixedly connected with anti-slip pads.
[0037] Specifically, by rotating the reciprocating wheel 8, the swing rod 7 swings, so that the connecting rod 6 drives the movable plate 27 to move, and by controlling the connecting pipe 5, external air enters the interior of the conveying box 4. By installing the support legs 11, the workbench 1 is more stable during operation.
[0038] Working principle: First, the staff puts the tool 17 to be polished on the top of the workbench 1, and starts the double-axis motor 24 inside the workbench 1, so that the fixed rod 26 drives the bevel gear 23 to rotate, and then the bevel gear 1 22 meshing with the bevel gear 23 rotates, so that the bidirectional screw 18 rotates. However, under the rotation of the bidirectional screw 18, the threaded sleeve 20 moves inside the limiting groove 19, thereby driving the connecting column 21 to move, so that the clamping plate 16 fixedly connected to the top of the connecting column 21 moves horizontally on the top of the workbench 1, so as to clamp and fix the tool 17. However, the anti-slip pad provided on the outside of the clamping plate 16 can prevent the tool 17 from moving during grinding and polishing. Then, driven by the electric guide rail 12, the polishing disc 14 moves to the position where the tool 17 needs to be polished. At the same time, driven by the cylinder 13, the polishing disc 14 polishes the tool 17 in many aspects.
[0039] Secondly, during polishing, the debris attached to the surface of the tool 17 can be started by the servo motor 9, causing the reciprocating wheel 8 to start rotating, and then driven by the reciprocating wheel 8, the swing rod 7 moves to the left, and then drives the connecting rod 6 to move, so that the movable plate 27 moves inside the conveying box 4, wherein when the movable plate 27 moves to the left, the airflow inside the conveying box 4 passes through the one-way valve 1 28 and is transported to the conveying pipe 3, and at the same time, the one-way valve 29 inside the connecting pipe 5 is closed, however, when the movable plate 27 moves to the right, the one-way valve 1 28 is closed, the one-way valve 2 29 is opened, and the air enters the interior of the conveying box 4 from the connecting pipe 5, wherein the airflow is transported from the conveying pipe 3 to the connecting plate 10, so that the airflow passes through the exhaust hole 15 to clean the powder attached to the surface of the tool 17, thereby improving work efficiency.
[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
