Description

Technical Field

[0001] This utility model relates to the field of aerospace parts processing technology, and in particular to a burr removal device for aerospace metal parts. Background Technology

[0002] Aviation equipment is now widely used in many fields such as travel, transportation, exploration, and military equipment. For large aviation equipment, there are many parts with complex shapes and large volumes. The most common processing technology used today is the machining and casting of these parts.

[0003] Parts produced by casting are prone to burrs at the casting joints. These burrs need to be removed to ensure part quality. However, the complex curved surfaces on the parts make burr removal difficult to perform with automated equipment, requiring manual burr removal by workers.

[0004] When manually removing burrs, workers use a handheld electric drill with a grinding head to grind the burrs and flash on the parts. During the grinding process, waste chips are generated, which not only make the workbench messy, but also easily adhere to the parts and can even get into the parts, making them difficult for workers to clean up.

The top and bottom of the treatment tank are respectively provided with an inlet and a slag discharge port. An outlet is connected to the side wall of the treatment tank. Both the inlet and outlet of the treatment tank are connected to a negative pressure pipe. A filter cylinder is coaxially arranged inside the treatment tank. The filter cylinder separates the outlet from the inlet and the slag discharge port of the treatment tank. The collection tank is detachably connected to the slag discharge port.

[0008] Furthermore, a connecting frame is coaxially rotatably installed inside the treatment tank. The connecting frame is annular, and a cleaning roller is rotatably installed on the connecting frame. The outer wall of the cleaning roller is provided with bristles that contact the outer wall of the filter cartridge. A drive motor is installed on the outer wall of the treatment tank, and the output shaft of the drive motor extends into the treatment tank and engages with the connecting frame for transmission.

[0009] Furthermore, an adsorption chamber is provided on the workbench below the operating table surface along the circumference of the operating table surface. A negative pressure branch pipe is connected to the negative pressure pipe on the side of the collection component away from the negative pressure adsorption component. The negative pressure branch pipe is connected to the adsorption chamber. Several adsorption holes connected to the adsorption chamber are opened on the operating table surface.

[0010] Furthermore, the adsorption hood includes a connecting tube and several movable tubes. One end of the connecting tube is fixedly connected to the gun body, and several movable tubes are sequentially and coaxially slidably sleeved on the outside of the connecting tube.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] This application discloses a burr removal device for metal parts used in aviation, referring to... Figure 1 and Figure 2 The system includes a workbench 1, on which is an operating surface 11 for placing parts. A power grinding gun is mounted on the workbench 1, specifically connected to a power socket on the workbench 1 via a power cord. The power grinding gun consists of a gun body 21 and a grinding head 22. The gun body 21 has a handle for the operator to hold, and a motor is housed within the gun body 21. The motor's output shaft extends out of the gun body 21 and connects to the grinding head 22. A suction cup 3 with an opening facing the grinding head 22 is connected to the gun body 21, and the opening of the suction cup 3 should be slightly higher than the grinding head 22. The workbench 1 is equipped with a negative pressure adsorption component, which is connected to the adsorption hood 3 through a negative pressure pipe 6. A collection component 5 for filtering and collecting waste is connected to the negative pressure pipe 6. By activating the negative pressure adsorption component, an adsorption force can be generated at the opening of the adsorption hood 3 to adsorb the waste on the parts removed by the grinding head 22. The waste is filtered and collected by the collection component 5, which prevents the waste from falling onto the workbench 11 or into the parts.

[0019] Specifically, the negative pressure adsorption assembly can employ a negative pressure suction pump 4, with its inlet end connected to the end of the negative pressure pipe 6 furthest from the adsorption hood 3. In this embodiment, the collection assembly 5 can include a treatment tank 51 and a collection tank 52. The top and bottom of the treatment tank 51 are respectively provided with an inlet and a slag discharge port, and an outlet is connected to the side wall of the treatment tank 51. Both the inlet and outlet of the treatment tank 51 are connected to the negative pressure pipe 6. A filter cylinder 53 is coaxially arranged inside the treatment tank 51, separating the outlet from the inlet and slag discharge port of the treatment tank 51 through the filter cylinder 53. The collection tank 52 is detachably connected to the slag discharge port. Waste particles adsorbed into the treatment tank 51 are intercepted on one side of the filter cylinder 53 and accumulate in the collection tank 52 for centralized collection. The collection tank 52 can be connected to the bottom of the treatment tank 51 using any one of the following connection methods: snap-fit ​​connection, threaded connection, or flange bolt connection.

[0020] Reference Figure 3 To maintain the negative pressure suction force in the negative pressure pipe 6 for a long time, a cleaning assembly for cleaning the filter cylinder 53 is also provided inside the treatment tank 51. Specifically, the cleaning assembly includes a connecting frame 54 and a cleaning roller 55. In this embodiment, both the treatment tank 51 and the filter cylinder 53 are cylindrical, and an installation gap is provided between the inner wall of the treatment pipe and the outer wall of the filter cylinder 53. An annular track is provided on the top wall of the installation gap. The connecting frame 54 is annular and coaxially installed in the installation gap inside the treatment tank 51, and is rotatably connected to the track. The cleaning roller 55 is rotatably installed on the connecting frame 54. The outer wall of the cleaning roller 55 is provided with bristles that contact the outer wall of the filter cylinder 53. The axis of rotation of the cleaning roller 55 is parallel to the axis of the filter cylinder 53, and several cleaning rollers 55 are provided circumferentially along the connecting frame 54. In this embodiment, there is one cleaning roller 55 on the connecting frame 54, and a drive motor 56 is provided on the outer wall of the treatment tank 51. The output shaft of the drive motor 56 extends into the treatment tank 51 and meshes with the connecting frame 54 for transmission. By starting the drive motor 56, the connecting frame 54 can be driven to rotate, so that the cleaning roller 55 moves along the circumferential direction of the installation gap on the outer wall of the filter cylinder 53. During the movement, the bristles on the cleaning roller 55 insert into the holes on the filter cylinder 53, pushing the waste debris that is blocked on the inner wall of the filter cylinder 53 into the interior and falling into the collection tank 52 below.

[0021] Furthermore, a ring of adsorption chambers is arranged around the circumference of the workbench 11 below the workbench surface 11. A negative pressure branch pipe 61 is connected to the negative pressure pipe 6 on the side of the collection component 5 away from the negative pressure adsorption component. The negative pressure branch pipe 61 communicates with the adsorption chambers. Several adsorption holes 12 communicating with the adsorption chambers are opened on the workbench surface 11. The adsorption holes 12 can adsorb the waste debris falling on the workbench surface 11. They can also be used by the operator to push the waste debris on the workbench surface 11 to the adsorption holes 12 and remove it from the workbench surface 11 in time during the grinding process, reducing the phenomenon of waste debris adhering to the parts due to static electricity when turning the parts.

[0022] Furthermore, in order to improve the adsorption effect of the adsorption hood 3 on the waste chips under grinding, the adsorption hood 3 can be composed of a connecting pipe 31 and several movable pipes 32. One end of the connecting pipe 31 is fixedly connected to the gun body 21, and the negative pressure pipe 6 is connected to the connecting pipe 31. Several movable pipes 32 are sequentially and coaxially slidably sleeved on the outside of the connecting pipe 31. Between the connecting pipe 31 and the connected movable pipe 32, as well as between two adjacent movable pipes 32, there are elastic elements 33 for driving the outer movable pipe 32 to slide towards the grinding head 22. Both the connecting pipe 31 and the movable pipe 32 are made of transparent material. Specifically, both the connecting tube 31 and the movable tube 32 can be made of tempered glass or transparent PC material. Connecting rings are fixedly attached to the ends of both the connecting tube 31 and the movable tube 32 near the gun body 21, protruding outwards. A guide rod 34 is fixedly connected to the connecting ring on the outermost movable tube 32 along the axial direction of the movable tube 32. A guide sleeve 35 is fixedly connected to the gun body 21. The guide rod 34 passes through the other connecting rings and is movably inserted into the guide sleeve 35. The elastic element 33 can be a spring, which is sleeved on the guide rod 34 and located between every two connecting rings to drive the two connecting rings away from each other. By making the connecting tube 31 and the movable tube 32 elastically connected, the length of the adsorption hood 3 can be extended, allowing the opening of the adsorption hood 3 to be closer to the contact position between the part and the grinding head 22. During the grinding process, after the opening of the adsorption hood 3 contacts the part, it is pushed and compressed. Without interfering with the normal operation of the grinding head 22, the opening of the adsorption hood 3 is brought as close to the part as possible, improving the adsorption and treatment effect of waste.

[0023] Furthermore, an adjusting screw 36, parallel to the guide rod 34, is fixedly connected to the connecting piece of the outermost movable tube 32, which is furthest from the gun body 21. An abutment piece is fixedly connected to the gun body 21, and the adjusting screw 36 passes through the abutment piece and is threadedly connected to an adjusting nut 37. In actual use, by adjusting the position of the adjusting nut 37 on the adjusting screw 36, the maximum extension distance of the adsorption cover 3 can be adjusted. Based on the length of the grinding head 22 and the position of the part being processed, the maximum length of the adsorption cover 3 can be adjusted to an appropriate length, reducing the amount of extension and retraction of the adsorption cover 3 during processing and reducing wear on the adsorption cover 3.
