Description

Technical Field

[0001] This application relates to the technical field of rust prevention treatment, and in particular to an automatic oiling device. Background Technology

[0002] In the processing of automotive parts, projection welding is commonly used to weld a nut or a bolt to different positions on a metal sheet, forming a strong connection point. This connection method has high strength and facilitates the assembly of the workpiece by technicians during subsequent assembly processes.

[0003] However, welding can damage the oxide film on the metal surface of the weld seam, and the weld seam is uneven or has tiny gaps, making it more susceptible to corrosion from oxygen and moisture in the air, thus accelerating the rusting process. Currently, rust prevention treatment of the weld seam is often carried out by manually applying oil. Technicians use a brush to apply an appropriate amount of rust-preventive oil evenly around the weld seam to achieve rust prevention treatment of the workpiece weld seam.

[0004] Regarding the aforementioned technologies, during the manual oiling process, technicians need to pick up and apply oil to each piece individually, which is labor-intensive and inefficient. Furthermore, due to limitations in the individual operating skills and experience of the technicians, the coating thickness of the rust-preventive oil is easily uneven, and problems such as missed coating and accumulation may occur, affecting the coating quality of the rust-preventive oil and reducing the rust-preventive performance of the workpiece. Therefore, improvements are needed. Utility Model Content

[0005] In order to improve the coating efficiency and quality of rust-preventive oil and enhance the rust-preventive performance of workpieces, this application provides an automatic oiling device.

[0006] The automatic oil-brushing device provided in this application adopts the following technical solution:

[0007] An automatic oiling device includes a frame and a worktable mounted on the frame. A workpiece is placed on the worktable. Two mounting blocks are provided on the frame, and rotating rods are rotatably mounted on the mounting blocks. The rotating rods are located above the worktable, and the two rotating rods correspond one-to-one with a nut and a bolt, respectively, and are coaxially arranged. A first power component is provided on the worktable to drive the rotating rods to rotate. A positioning component is provided on the worktable to position and fix the workpiece. The frame is provided with a conveying component for conveying the workpiece, a cleaning component for cleaning the weld seams of the workpiece, and a spraying component for rust prevention treatment of the weld seams of the workpiece.

[0008] The spraying assembly includes a connecting plate on the side wall of the rotating rod near the workbench. A nozzle is provided on the connecting plate and is inclined toward the nut / bolt. An air supply pipe and an oil supply pipe are connected to the nozzle. The end of the air supply pipe away from the nozzle is connected to a stable and clean air source. A solenoid valve is also provided on the air supply pipe. An oil tank for storing rust-preventive oil is provided on the frame. The end of the oil supply pipe away from the nozzle is connected to the oil tank. An oil pump is also provided on the oil supply pipe.

[0009] By adopting the above technical solution, when rust prevention treatment is required for the workpiece, the workpiece is transported to the worktable by the conveying component and positioned and fixed by the positioning component to realize the loading of the workpiece. Then, the cleaning component cleans the dust, grease and other impurities at the weld, improving the cleanliness of the workpiece weld, which is conducive to the formation of a uniform coating of rust-preventive oil and improving the rust prevention effect.

[0010] Then the first power component operates, driving the rotating rod to rotate, which in turn drives the connecting plate and the nozzle to rotate around the axis of the rotating rod. At the same time, the solenoid valve and the oil pump are opened. The oil pump draws the rust-preventive oil in the oil storage tank into the nozzle through the oil delivery pipe. High-pressure gas enters the nozzle from the gas delivery pipe, thereby atomizing the rust-preventive oil. As the nozzle rotates, the rust-preventive oil is evenly sprayed onto the weld seam of the workpiece and the nut / bolt, achieving rust prevention treatment of the weld seam of the workpiece. Then the conveying component unloads the treated workpiece.

[0011] The above solution enables automated cleaning and rust-preventive oil spraying, ensuring rapid and even application of the rust-preventive oil to the workpiece surface. This reduces issues such as missed areas and accumulation, improves the spraying effect of the rust-preventive oil, enhances the rust-preventive performance of the workpiece, reduces waste of the rust-preventive oil, and increases spraying efficiency.

[0012] Optionally, the cleaning assembly includes a brush that is slidably and rotatably mounted on the connecting plate. The brush is located on the side of the connecting plate away from the rotating rod, and the brush is arranged opposite to the nozzle. The brush is movably fitted to the weld seam of the workpiece. The frame is provided with a synchronizing component that drives the brush to rotate and a lifting component that drives the brush to slide and rise.

[0013] By adopting the above technical solution, when cleaning the weld seam of the workpiece, the lifting component drives the brush to descend and make the brush fit against the weld seam of the workpiece. Then, the first power component drives the rotating rod and the connecting plate to rotate, thereby driving the brush to rotate around the axis of the rotating rod, thus cleaning the weld seam of the workpiece. At the same time, the synchronizing component drives the brush to rotate, improving the cleaning effect of the brush and further improving the cleanliness of the weld seam of the workpiece.

[0014] When performing rust prevention treatment on the weld seam of the workpiece, the lifting component drives the brush to rise, separating the brush from the workpiece. Then, the first power component drives the rotating rod to rotate in the opposite direction, realizing the spraying of rust-preventive oil. At this time, the brush is separated from the workpiece, which is less likely to damage the sprayed rust-preventive oil coating and improves the rust prevention performance of the workpiece.

[0015] Optionally, the lifting component includes a sliding rod coaxially mounted on the brush, the sliding rod being located on the side wall of the brush away from the worktable, and an electric actuator being provided on the side wall of the mounting block away from the worktable, the output end of the electric actuator being rotatably connected to the end of the sliding rod away from the brush.

[0016] By adopting the above technical solution, when it is necessary to drive the brush to rise or fall, the electric actuator drives the sliding rod to slide away from / near the worktable, thereby driving the brush to slide and realizing the brush rising / falling. Since the output end of the electric actuator is rotatably connected to the sliding rod, it is not easy to obstruct the rotation of the sliding rod and the brush when cleaning the weld seam of the workpiece.

[0017] Optionally, the synchronizing element includes a synchronizing internal gear located at the bottom of the mounting block, the synchronizing internal gear being coaxially arranged with the rotating rod, and a synchronizing external gear rotatably arranged at the bottom of the mounting block, the synchronizing internal gear meshing with the synchronizing external gear, the sliding rod slidingly passing through the synchronizing external gear, and the cross-section of the sliding rod being polygonal, the synchronizing external gear having a limiting hole, and the sliding rod being movably abutting against the inner sidewall of the limiting hole.

[0018] By adopting the above technical solution, when the sliding rod slides, it slides within the limiting hole, which does not easily obstruct the raising and lowering of the brush. When the rotating rod rotates, the brush rotates around the axis of the rotating rod. Since the synchronous internal gear and the synchronous external gear mesh, the synchronous external gear is driven to rotate. At this time, the sliding rod abuts against the inner wall of the limiting hole, so that the sliding rod and the synchronous external gear rotate synchronously, thereby realizing the rotation of the brush. The coordinated and synchronous operation of the brush rotation around the axis of the rotating rod and the brush rotation improves the cleaning effect and saves power.

[0019] Optionally, the positioning component includes a rotating disk that is slidably and rotatably disposed on the worktable. The rotating disk is provided with a positioning block. The workpiece is placed on top of the positioning block. The positioning block is movably located directly below the mounting block. The positioning block corresponds to the mounting block and the conveying component. The mounting block is provided with a clamping block on the side wall near the worktable. The clamping block is movably clamped to the side wall of the workpiece that is close to it. The worktable is provided with a driving component that drives the rotating disk to slide and rotate.

[0020] By adopting the above technical solution, when the workpiece needs to be rust-proofed, the positioning block corresponds to the conveying component. At this time, it is the initial position of the rotating disk. The conveying component places the workpiece on the positioning block, and then the driving component drives the rotating disk to rotate until the positioning block is directly below the mounting block. Then the driving component drives the rotating disk to slide towards the mounting block, so that the abutting block and the side wall of the workpiece are close to each other, thereby fixing the workpiece and realizing the loading of the workpiece. Then the weld seam of the workpiece is cleaned and rust-proof oil is sprayed.

[0021] After the rust prevention treatment is completed, the drive unit drives the rotating disk to slide away from the mounting block, so that the clamping block is separated from the workpiece, thereby unlocking the workpiece. Then the drive unit drives the rotating disk to rotate, so that the rotating disk rotates to the initial position. At this time, the conveying component unloads the processed workpiece and loads it again. This cycle is repeated to complete the automated oiling process of the workpiece.

[0022] With the above solution, the rotating disk can be fixed / unlocked by sliding a short distance towards / away from the clamping block. At the same time, when loading and unloading workpieces, the positioning block corresponds to the conveying component, and the nozzle and brush do not easily obstruct the conveying component from loading and unloading, which facilitates the loading and unloading of workpieces. In addition, the equipment has a compact structure.

[0023] Optionally, the driving component includes a support cylinder mounted on the worktable, the support cylinder being coaxially arranged with the rotating disk, a drive screw being coaxially rotatably mounted inside the support cylinder, a screw nut being coaxially threaded onto the drive screw, a guide post being provided on the screw nut, one end of the guide post protruding from the outer peripheral wall of the support cylinder, the protruding end of the guide post being connected to the rotating disk, a guide groove being formed on the outer peripheral wall of the support cylinder, the guide groove being connected to the inside of the support cylinder, the guide post being movably located within the guide groove and being movably abutting against the inner side wall of the guide groove, the guide groove including a sliding groove and a rotating groove, the sliding groove being formed along the axial direction of the support cylinder, the rotating groove being formed along the radial direction of the support cylinder, and the sliding groove being connected to the rotating groove, the rotating groove being located at one end of the support cylinder near the rotating disk, and a second power component for driving the drive screw to rotate being provided on the worktable.

[0024] By adopting the above technical solution, when the workpiece is fixed, the second power component drives the active lead screw to rotate. At this time, the guide column is located in the rotating groove and abuts against the inner top wall of the rotating groove, so that the active lead screw and the lead screw nut maintain a constant relative position. The guide column and the lead screw nut can only rotate in the rotating groove until the guide column rotates into the sliding groove. At this time, the rotating disk rotates until the positioning block is directly below the mounting block.

[0025] Then the active lead screw continues to rotate. At this time, the guide post abuts against the inner wall of the sliding groove, thereby restricting the rotation of the guide post and the lead screw nut. This causes the lead screw nut and the guide post to slide along the opening direction of the sliding groove, thereby causing the rotating disk to slide closer to the mounting block until the abutting block abuts against the side wall of the workpiece, thus fixing the workpiece.

[0026] When unlocking the workpiece, the second power component drives the active lead screw to rotate in the opposite direction. At this time, the guide post abuts against the inner wall of the sliding groove, thereby restricting the rotation of the guide post and the lead screw nut. This causes the lead screw nut and the guide post to slide along the opening direction of the sliding groove, thereby causing the rotating disk to slide away from the mounting block until the guide post abuts against the inner bottom wall of the rotating groove, thus unlocking the workpiece.

[0027] Then the active screw continues to rotate in the opposite direction. At this time, the guide column abuts against the inner bottom wall of the rotating groove, so that the active screw and the screw nut maintain a constant relative position. The guide column and the screw nut can only rotate within the rotating groove until the guide column rotates into the rotating groove and abuts against the inner side wall of the rotating groove until the rotating disk rotates to the initial position. The structure is simple and has high stability.

[0028] Optionally, the positioning block has two positioning holes, and a positioning bushing is coaxially provided in each positioning hole. One of the positioning holes corresponds to a nut welded to the workpiece, and a positioning rod is provided in this positioning hole. The positioning rod is movably fitted with the inner peripheral wall of the corresponding positioning bushing, and the nut is coaxially movably sleeved on the positioning rod. The other positioning hole corresponds to a screw welded to the workpiece, and the threaded end of the screw is coaxially movably located in the positioning bushing. The clamping block, the positioning bushing, and the positioning rod are all made of copper.

[0029] By adopting the above technical solution, when feeding the workpiece, the conveying component places the workpiece on the positioning block, and the nut welded to the workpiece is coaxially sleeved on the positioning rod. At the same time, the threaded end of the bolt welded to the workpiece is coaxially inserted into the corresponding positioning bushing to achieve the positioning of the workpiece. When the rotating disk slides towards the mounting block, the workpiece is not easy to move relative to the positioning block.

[0030] When fixing the workpiece, the rotating disk slides towards the mounting block. At this time, the clamping block and the side wall of the workpiece are pressed together. Meanwhile, the clamping block, positioning bushing and positioning rod are all made of copper, which reduces the risk of damage to the end face of the workpiece, the nut thread and the bolt thread.

[0031] Optionally, the connecting plate is provided with an isolation sponge at the nozzle. The isolation sponge is funnel-shaped, and the nozzle is located inside the isolation sponge. Magnetic blocks are provided on the sidewalls of the isolation sponge and the connecting plate that are close to each other, and the two magnetic blocks are magnetically connected.

[0032] By adopting the above technical solution, when spraying rust-preventive oil on the nozzle, the set isolation sponge absorbs the rust-preventive oil that is sprayed outside the controllable range, thereby improving the cleanliness of the working environment. When the isolation sponge absorbs too much rust-preventive oil, the technicians remove the isolation sponge and clean or replace it. At this time, the isolation sponge is fixed to the connecting plate by the set magnetic block, which makes it easy for the technicians to disassemble and install.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. The system comprises a worktable, conveying assembly, mounting block, rotating rod, connecting plate, nozzle, first power component, brush, sliding rod, electric actuator, synchronous internal gear, and synchronous external gear. When rust prevention treatment is required, the workpiece is placed on the worktable via the conveying assembly. The electric actuator then moves the sliding rod closer to the worktable, raising and lowering the brush to bring it into contact with the weld seam of the workpiece. The first power component then operates, driving the rotating rod and connecting plate to rotate. This causes the brush and synchronous external gear to rotate around the axis of the rotating rod, which in turn drives the synchronous internal gear to rotate the synchronous external gear, resulting in the brush rotating. This cleans the weld seam of the workpiece, improving its cleanliness and facilitating the formation of a uniform coating with the subsequent rust-preventive oil, thus enhancing the rust prevention effect.

[0035] Then, the electric actuator drives the sliding rod to slide away from the worktable, raising the brush and separating it from the weld seam of the workpiece. The first power component then drives the rotating rod to rotate in the opposite direction, causing the connecting plate and spray head to rotate around the axis of the rotating rod, spraying rust-preventive oil towards the weld seam of the workpiece. At this point, the brush is separated from the workpiece, minimizing damage to the sprayed rust-preventive oil coating. This achieves automated cleaning and rust-preventive oil spraying, ensuring rapid and even application of the rust-preventive oil to the workpiece surface, reducing issues such as missed areas and accumulation, improving the spraying effect, and thus enhancing the rust-preventive oil's anti-rust performance. Simultaneously, it reduces rust-preventive oil waste and increases spraying efficiency.

[0036] 2. The rotating disk, positioning block, clamping block, positioning bushing, positioning rod, and driving component are configured to perform rust prevention treatment on the workpiece. When rust prevention treatment is required, the positioning block corresponds to the conveying assembly, which is the initial position of the rotating disk. The conveying assembly places the workpiece on the positioning block, and the nut welded to the workpiece is coaxially sleeved on the positioning rod. Simultaneously, the threaded end of the bolt welded to the workpiece is coaxially inserted into the corresponding positioning bushing, thus positioning the workpiece. Then, the driving component drives the rotating disk to rotate until the positioning block is directly below the mounting block. The driving component then drives the rotating disk to slide closer to the mounting block, causing the clamping block to abut against the adjacent sidewalls of the workpiece, thus fixing the workpiece and allowing it to be loaded. Afterward, the weld seam of the workpiece is cleaned and rust-preventive oil is sprayed. The clamping block, positioning bushing, and positioning rod are all made of copper, reducing the risk of damage to the workpiece end face, nut threads, and bolt threads.

[0037] After the rust prevention treatment is completed, the drive unit drives the rotating disk to slide away from the mounting block, so that the clamping block is separated from the workpiece, thereby unlocking the workpiece. Then the drive unit drives the rotating disk to rotate, so that the rotating disk rotates to the initial position. At this time, the conveying component unloads the processed workpiece and loads it again. This cycle is repeated to complete the automated oiling process of the workpiece.

[0038] With the above solution, and the rotating disk sliding a short distance towards / away from the clamping block, the workpiece can be fixed / unlocked. At the same time, when loading and unloading the workpiece, the positioning block corresponds to the conveying component, and the nozzle and brush do not easily obstruct the conveying component from loading and unloading, which facilitates the loading and unloading of the workpiece and makes the equipment structure simple and compact.

[0039] 3. With the help of the isolation sponge and magnetic blocks, when the anti-rust oil is sprayed from the nozzle, the isolation sponge absorbs the anti-rust oil that is sprayed outside the controllable range, thereby improving the cleanliness of the working environment. When the isolation sponge absorbs too much anti-rust oil, the technicians can remove the isolation sponge and clean or replace it. At this time, the isolation sponge is fixed to the connecting plate by the magnetic blocks, which makes it easy for technicians to disassemble and install. Attached Figure Description

[0045] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0046] This application discloses an automatic oiling device. (Refer to...) Figure 1 and Figure 2 An automatic oiling device includes a frame 1 placed vertically on the ground and a worktable 2 fixed to the bottom of the frame 1. The workpiece 7 is placed on the worktable 2. Two mounting blocks 21 are detachably fixed on the top side of the frame 1. Rotating rods 22 are rotatably connected to the mounting blocks 21. The two rotating rods 22 correspond one-to-one with nuts and bolts and are coaxially arranged. The rotation axis of the rotating rods 22 is parallel to the height direction of the frame 1. The frame 1 is provided with a conveying assembly 6 for conveying the workpiece 7. The conveying assembly 6 includes a conveyor belt 62 fixed to the frame 1, a robotic arm 61, and a storage box 63. The workpiece 7 to be rust-proofed is located on the conveyor belt 62 and is conveyed to the corresponding position of the robotic arm 61 by the conveyor belt 62.

[0047] To position and fix the workpiece 7, a positioning component 5 is provided on the worktable 2, as shown in the reference. Figure 1 and Figure 2The positioning component 5 includes a rotating disk 51 that is slidably and rotatably connected to the top of the worktable 2. The sliding direction of the rotating disk 51 is parallel to the axis of the rotating rod 22, and the rotation axis of the rotating disk 51 is parallel to the rotation axis of the rotating rod 22. A positioning block 52 is fixed on the top of the rotating disk 51. The workpiece 7 is placed on the top of the positioning block 52. The positioning block 52 is movably located directly below the mounting block 21. The positioning block 52 corresponds to the mounting block 21 and the robotic arm 61. A clamping block 53 is fixed on the side wall of the mounting block 21 near the worktable 2. The clamping block 53 is movably clamped to the side wall of the workpiece 7 that is close to each other.

[0048] Two positioning holes 55 are provided on the side wall of the positioning block 52 away from the rotating disk 51. A positioning bushing 56 is coaxially fixed in the positioning hole 55. One positioning hole 55 corresponds to the nut welded to the workpiece 7, and a positioning rod 57 is detachably fixed in this positioning hole 55. The positioning rod 57 is movably fitted with the inner peripheral wall of the corresponding positioning bushing 56. The nut is coaxially movably sleeved on the positioning rod 57. The other positioning hole 55 corresponds to the screw welded to the workpiece 7, and the threaded end of the screw is coaxially movably located in the positioning bushing 56. The clamping block 53, the positioning bushing 56 and the positioning rod 57 are all made of copper. In this application, only one bolt and one nut are installed on the workpiece 7. In other embodiments, multiple bolts and nuts can be installed. The relevant technicians need to set multiple rotating rods 22, and the multiple rotating rods 22 correspond one-to-one with the bolts and nuts. The corresponding mounting block 21 also corresponds one-to-one with the corresponding rotating rod 22.

[0049] To drive the rotating disk 51 to slide and rotate, a driving component 54 is provided on the worktable 2, as shown in the reference. Figure 1 , Figure 2 and Figure 3The driving component 54 includes a support cylinder 541 fixed on the worktable 2. The support cylinder 541 is coaxially arranged with the rotating disk 51. A drive screw 542 is coaxially rotatably connected inside the support cylinder 541. The rotation axis of the drive screw 542 is coaxial with the rotation axis of the rotating disk 51. A screw nut 543 is coaxially threaded on the drive screw 542. A guide post 544 is fixed on the screw nut 543. One end of the guide post 544 protrudes from the outer peripheral wall of the support cylinder 541 and is fixedly connected to the rotating disk 51. A guide is provided on the outer peripheral wall of the support cylinder 541. The guide groove is connected to the support cylinder 541. The guide column 544 is movably located in the guide groove and is movably abutted against the inner side wall of the guide groove. The guide groove includes a sliding groove 545 and a rotating groove 546. The sliding groove 545 is opened along the axial direction of the support cylinder 541, and the rotating groove 546 is opened along the radial direction of the support cylinder 541. The sliding groove 545 and the rotating groove 546 are connected. The rotating groove 546 is located at one end of the support cylinder 541 near the rotating disk 51. A second power component 547 that drives the active lead screw 542 to rotate is fixed on the worktable 2. In this application, the first power component 23 is a drive motor.

[0050] When rust prevention treatment is required for workpiece 7, the positioning block 52 corresponds to the conveying component 6. At this time, the initial position of the rotating disk 51 is reached. The conveyor belt 62 conveys workpiece 7 to the corresponding position of the robotic arm 61. Then, the robotic arm 61 places workpiece 7 on the positioning block 52 and makes the nut welded to workpiece 7 coaxially sleeved on the positioning rod 57. At the same time, the threaded end of the bolt welded to workpiece 7 is coaxially inserted into the corresponding positioning bushing 56 to achieve positioning of workpiece 7.

[0051] The second power component 547 drives the active lead screw 542 to rotate. At this time, the guide column 544 is located in the rotating groove and abuts against the inner top wall of the rotating groove, so that the active lead screw 542 and the lead screw nut 543 maintain a constant relative position. The guide column 544 and the lead screw nut 543 can only rotate in the rotating groove until the guide column 544 rotates into the sliding groove 545. At this time, the rotating disk 51 rotates until the positioning block 52 is located directly below the mounting block 21, and the workpiece 7 is not easy to move relative to the positioning block 52.

[0052] Then the active lead screw 542 continues to rotate. At this time, the guide post 544 abuts against the inner wall of the sliding groove 545, thereby restricting the rotation of the guide post 544 and the lead screw nut 543. This causes the lead screw nut 543 and the guide post 544 to slide along the opening direction of the sliding groove 545, thereby causing the rotating disk 51 to slide closer to the mounting block 21 until the abutting block 53 abuts against the side wall of the workpiece 7. The second power component 547 stops working, thus fixing the workpiece 7 and loading the workpiece 7. Then, the workpiece 7 is subjected to rust prevention treatment.

[0053] After the rust prevention treatment is completed, the second power component 547 drives the active lead screw 542 to rotate in the opposite direction. At this time, the guide post 544 abuts against the inner wall of the sliding groove 545, thereby restricting the rotation of the guide post 544 and the lead screw nut 543, causing the lead screw nut 543 and the guide post 544 to slide along the opening direction of the sliding groove 545, thereby causing the rotating disk 51 to slide away from the mounting block 21 until the guide post 544 abuts against the inner bottom wall of the rotating groove, thus unlocking the workpiece 7.

[0054] Then the active lead screw 542 continues to rotate in the opposite direction. At this time, the guide column 544 abuts against the inner bottom wall of the rotating groove, so that the active lead screw 542 and the lead screw nut 543 maintain a constant relative position. The guide column 544 and the lead screw nut 543 can only rotate within the rotating groove until the guide column 544 rotates into the rotating groove and abuts against the inner side wall of the rotating groove, until the rotating disk 51 rotates to the initial position. The second power component 547 stops working. At this time, the robotic arm 61 removes the rust-proofed workpiece 7 and puts it into the storage box 63, realizing the unloading of workpiece 7, and loading the next workpiece 7 to be rust-proofed. This cycle completes the automated rust-proofing treatment of workpiece 7.

[0055] With the above scheme, the rotating disk 51 can slide a short distance closer to / away from the clamping block 53 to fix / unlock the workpiece 7. At the same time, when loading and unloading the workpiece 7, the positioning block 52 corresponds to the conveying component 6, and the nozzle 31 and brush 41 do not obstruct the conveying component 6 from loading and unloading, which facilitates the loading and unloading of the workpiece 7. As a result, the equipment has a compact structure, simple structure and high stability.

[0056] Furthermore, in order to perform rust prevention treatment on workpiece 7, a spraying assembly 3 is installed on the frame 1, as shown in the figure. Figure 2 and Figure 4 The spraying assembly 3 includes a connecting plate 32 fixed to the rotating rod 22 near the side wall of the workbench 2. A nozzle 31 is provided on the connecting plate 32, and the nozzle 31 is inclined towards the nut / bolt. An isolation sponge 36 is provided on the connecting plate 32 at the nozzle 31. The isolation sponge 36 is funnel-shaped, and the nozzle 31 is located inside the isolation sponge 36 to absorb the anti-rust oil sprayed outside the controllable range, thereby improving the cleanliness of the working environment. At the same time, magnetic blocks 37 are fixed on the side walls of the isolation sponge 36 and the connecting plate 32 that are close to each other. The two magnetic blocks 37 are magnetically connected, which makes it easy for technicians to disassemble and install the isolation sponge 36.

[0057] The workbench 2 is equipped with a first power component 23 that drives the rotating rod 22 to rotate. In this application, the first power component 23 is also a drive motor. The nozzle 31 is connected to an air supply pipe and an oil supply pipe. The end of the air supply pipe away from the nozzle 31 is connected to a stable and clean air source. A solenoid valve 33 is also fixed on the air supply pipe. An oil storage tank 35 for storing rust-preventive oil is fixed on the frame 1. The end of the oil supply pipe away from the nozzle 31 is connected to the oil storage tank 35. An oil pump 34 is also fixed on the oil supply pipe.

[0058] To clean the weld seam of workpiece 7, a cleaning component 4 is also installed on the frame 1, as shown in the reference. Figure 2 and Figure 4 The cleaning component 4 includes a brush 41 that is slidably and rotatably connected to the connecting plate 32. In this application, the brush 41 is made of nylon. The brush 41 is located on the side of the connecting plate 32 away from the rotating rod 22, and the brush 41 is arranged opposite to the nozzle 31. The rotation axis of the brush 41 is parallel to the rotation axis of the rotating rod 22. The sliding direction of the brush 41 is parallel to the axial direction of the rotating rod 22. The brush 41 is in contact with the weld of the workpiece 7. The frame 1 is provided with a synchronizing component 43 for driving the brush 41 to rotate and a lifting component 42 for driving the brush 41 to slide and lift.

[0059] Reference Figure 2 and Figure 4 The lifting component 42 includes a sliding rod 421 coaxially fixed to the brush 41. The sliding rod 421 is fixed to the side wall of the brush 41 away from the worktable 2. An electric push rod 423 is fixed to the side wall of the mounting block 21 away from the worktable 2. The output end of the electric push rod 423 is rotatably connected to the end of the sliding rod 421 away from the brush 41.

[0060] Reference Figure 2 and Figure 4 The synchronizing element 43 includes a synchronizing internal gear 431 fixed to the bottom of the mounting block 21. The synchronizing internal gear 431 is coaxially arranged with the rotating rod 22. The bottom of the mounting block 21 is also rotatably connected to a synchronizing external gear 432. The synchronizing internal gear 431 and the synchronizing external gear 432 mesh with each other. The sliding rod 421 slides through the synchronizing external gear 432. The cross-section of the sliding rod 421 is polygonal. A limiting hole 422 is opened on the synchronizing external gear 432. The sliding rod 421 is movably pressed against the inner sidewall of the limiting hole 422. In this application, the cross-section of the sliding rod 421 is a regular quadrilateral shape. In other embodiments, the cross-section of the sliding rod 421 can also be a polygon such as a triangle, pentagon, or hexagon. As long as the sliding rod 421 can slide within the limiting hole 422 and the synchronizing external gear 432 can drive the sliding rod 421 to rotate synchronously.

[0061] After the workpiece 7 is fixed, the electric actuator 423 drives the sliding rod 421 to slide within the limiting hole 422, and drives the brush 41 to slide closer to the worktable 2, so that the brush 41 is in contact with the weld of the workpiece 7. Then the first power component 23 works, driving the rotating rod 22 and the connecting plate 32 to rotate, thereby driving the nozzle 31 and the brush 41 to rotate around the axis of the rotating rod 22, thus cleaning the weld of the workpiece 7. At the same time, since the synchronous internal gear 431 and the synchronous external gear 432 mesh, the synchronous external gear 432 is driven to rotate. At this time, the sliding rod 421 abuts against the inner wall of the limiting hole 422, so that the sliding rod 421 and the synchronous external gear 432 rotate synchronously, thereby realizing the rotation of the brush 41, improving the cleaning effect of the brush 41, improving the cleanliness of the weld of the workpiece 7, which is conducive to the formation of a uniform coating of the subsequent anti-rust oil and improving the anti-rust effect.

[0062] When performing rust prevention treatment on workpiece 7, the electric actuator 423 drives the sliding rod 421 to slide within the limiting hole 422, and drives the brush 41 to slide away from the worktable 2, separating the brush 41 from the workpiece 7. Then, the first power component 23 operates, driving the rotating rod 22 to rotate in the opposite direction, thereby causing the connecting plate 32, brush 41, and nozzle 31 to rotate around the axis of the rotating rod 22. At the same time, the solenoid valve 33 and the oil pump 34 are opened, and the oil pump 34 draws the rust-preventive oil in the oil storage tank 35 into the nozzle 31 through the oil delivery pipe. High-pressure gas enters the nozzle from the gas delivery pipe. The nozzle 31 atomizes the rust-preventive oil, and as the nozzle 31 rotates, it evenly sprays the rust-preventive oil onto the weld seam of the nut / bolt on the workpiece 7, achieving rust prevention treatment at the weld seam of the workpiece 7. At the same time, the brush 41 separates from the workpiece 7, which is less likely to damage the sprayed rust-preventive oil coating, realizing automated cleaning and spraying of rust-preventive oil, and ensuring that the rust-preventive oil is quickly and evenly sprayed onto the surface of the workpiece 7, reducing problems such as missed coating and accumulation, improving the spraying effect of the rust-preventive oil, thereby improving the rust prevention performance of the workpiece 7, while reducing the waste of rust-preventive oil and improving the spraying efficiency.

[0063] Meanwhile, when the anti-rust oil is sprayed on the nozzle 31, the isolation sponge 36 is used to absorb the anti-rust oil that is sprayed outside the controllable range, thereby improving the cleanliness of the working environment. When the isolation sponge 36 absorbs too much anti-rust oil, the technicians remove the isolation sponge 36 and clean or replace it. At this time, the isolation sponge 36 is fixed to the connecting plate 32 by the magnetic block 37, which makes it easy for the technicians to disassemble and install.

[0064] The implementation principle of the automatic oiling device in this application embodiment is as follows: When the workpiece 7 needs to be rust-proofed, the conveyor belt 62 transports the workpiece 7 to the corresponding position of the robotic arm 61. Then, the robotic arm 61 places the workpiece 7 on the positioning block 52 to achieve positioning of the workpiece 7. Then, the second power component 547 works to drive the active lead screw 542 to rotate. At this time, the guide column 544 is located in the rotating groove and abuts against the inner top wall of the rotating groove, so that the active lead screw 542 and the lead screw nut 543 maintain a constant relative position. The guide column 544 and the lead screw nut 543 can only move within the rotating groove. Rotate until the guide post 544 rotates into the sliding groove 545. At this time, the rotating disk 51 rotates until the positioning block 52 is directly below the mounting block 21. Then the drive screw 542 continues to rotate. At this time, the guide post 544 abuts against the inner wall of the sliding groove 545, thereby restricting the rotation of the guide post 544 and the screw nut 543. This allows the screw nut 543 and the guide post 544 to slide along the opening direction of the sliding groove 545, thereby causing the rotating disk 51 to slide closer to the mounting block 21 until the abutting block 53 abuts against the side wall of the workpiece 7, thus fixing the workpiece 7.

[0065] Then, the electric actuator 423 drives the brush 41 to descend and come into contact with the weld of the workpiece 7. Then, the first power component 23 works, driving the rotating rod 22 and the connecting plate 32 to rotate, and driving the brush 41 to rotate around the axis of the rotating rod 22. At the same time, the synchronous internal gear 431 drives the synchronous external gear 432 to rotate, realizing the rotation of the brush 41 and cleaning the weld of the workpiece 7. Then, the electric actuator 423 drives the brush 41 to rise, separating the brush 41 from the workpiece 7. Then, the first power component 23 drives the rotating rod 22 and the connecting plate 32 to rotate in opposite directions, and drives the nozzle 31 to rotate around the rotation axis of the rotating rod 22. At the same time, the solenoid valve 33 and the oil pump 34 are opened. The oil pump 34 draws the rust-preventive oil in the oil storage tank 35 into the nozzle 31 through the oil pipe. High-pressure gas enters the nozzle 31 from the gas pipe, thereby atomizing the rust-preventive oil. As the nozzle 31 rotates, the rust-preventive oil is evenly sprayed onto the weld of the nut / bolt of the workpiece 7.

[0066] After the rust prevention treatment is completed, the second power component 547 drives the active lead screw 542 to rotate in the opposite direction. At this time, the guide post 544 abuts against the inner wall of the sliding groove 545, thereby restricting the rotation of the guide post 544 and the lead screw nut 543, causing the lead screw nut 543 and the guide post 544 to slide along the opening direction of the sliding groove 545, thereby causing the rotating disk 51 to slide away from the mounting block 21 until the guide post 544 abuts against the inner bottom wall of the rotating groove, thus unlocking the workpiece 7.

[0067] Then the active lead screw 542 continues to rotate in the opposite direction. At this time, the guide column 544 abuts against the inner bottom wall of the rotating groove, so that the active lead screw 542 and the lead screw nut 543 maintain a constant relative position. The guide column 544 and the lead screw nut 543 can only rotate within the rotating groove until the guide column 544 rotates into the rotating groove and abuts against the inner side wall of the rotating groove, until the rotating disk 51 rotates to the initial position. The second power component 547 stops working. At this time, the robotic arm 61 removes the rust-proofed workpiece 7 and puts it into the storage box 63, realizing the unloading of workpiece 7, and loading the next workpiece 7 to be rust-proofed. This cycle completes the automated rust-proofing treatment of workpiece 7.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
