Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, specifically to a sheet metal oiling device. Background Technology

[0002] To ensure the quality of sheet metal during high-speed drawing, applying drawing oil to specific areas of the sheet metal using an oiling machine before stamping is a common process in automobile manufacturing.

[0003] In existing oiling machines, the drive components used to move the sheet metal are generally driven by a conveyor belt via belt transmission. However, due to the varying shapes of the sheet metal, some specially shaped sheets are prone to cutting the conveyor belt during transport. Since the conveyor belt in existing oiling machines needs to maintain a certain tension to transport the sheet metal, once the conveyor belt is cut, it is easy for it to break under the tension.

[0004] In addition, if one or more conveyor belts in the existing oiling machine break, it will affect the conveying function and require the machine to be stopped for maintenance, thus affecting production efficiency. Utility Model Content

[0005] To address the aforementioned issues, this application provides a sheet metal oiling device that can effectively reduce the risk of conveyor belt breakage, thereby ensuring the stability of the oiling process.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A sheet metal coating device includes a machine body, a conveying unit on the machine body, and spraying units located on the upper and lower sides of the conveying unit on the machine body. The conveying unit includes a drive motor and several transmission shafts.

[0008] The drive shaft is rotatably connected to the fuselage assembly;

[0009] The drive shafts are respectively connected to the power output terminals of the drive motors;

[0010] The drive shaft is provided with several pulleys, and a conveyor belt is fitted onto the pulleys.

[0011] Furthermore, the fuselage assembly includes two uprights, with an upper crossbeam and a lower crossbeam arranged sequentially from top to bottom between the two uprights. The drive shaft is mounted on the lower crossbeam, and the drive motor is mounted on the outside of one of the uprights and connected to the drive shaft via a first transmission mechanism.

[0012] Furthermore, the drive shaft includes a working shaft section and a transmission shaft section. The pulley is disposed on the working shaft section. Several detachable transmission brackets are disposed on the lower crossbeam. The working shaft section is rotatably connected to the transmission brackets through a bearing assembly. One end of the transmission shaft section is rotatably connected to the upright frame, and the other end of the transmission shaft is connected to the working shaft section.

[0013] Furthermore, the conveying assembly also includes a detection shaft, one end of which is rotatably connected to the upright frame, and the other end of which is connected to a transmission shaft. The detection shaft is also connected to the input end of an encoder.

[0014] Furthermore, the transmission bracket is provided with a clearance slot for avoiding the working shaft section of the transmission shaft, and the working shaft section is rotatably connected to the transmission bracket via a bearing with a mounting seat.

[0015] Furthermore, a base is provided at the lower end of the upright frame, a traveling wheel is provided on the base, and a traveling motor is provided on one of the bases. The power output shaft of the traveling motor is connected to the traveling wheel through a second transmission mechanism.

[0016] Furthermore, a transition plate is provided above the drive shaft, and the transition plate is provided with clearance openings corresponding to the pulleys one by one. The upper end of the conveyor belt protrudes above the transition plate through the clearance openings.

[0017] Furthermore, an auxiliary roller assembly is provided between two adjacent drive shafts.

[0018] Furthermore, the machine body is provided with a protective cover assembly, the conveying assembly is located inside the protective cover assembly, the protective cover assembly is provided with a feed inlet and a discharge outlet, an oil mist collector is provided on the outside of the protective cover assembly, and the oil inlet of the oil mist collector is connected to the inside of the protective cover assembly.

[0019] Furthermore, the oil tank is connected to the oil receiving box at the bottom of the protective cover via an oil return pipe.

[0020] The beneficial effects of this utility model are:

[0021] 1. The sheet metal oiling device provided in this application abandons the traditional belt conveyor method and instead uses several rows of pulleys, with a conveyor belt fitted around the outer circumference of each pulley. The sheet metal is propelled by the friction between the conveyor belt and the sheet metal. In this way, on the one hand, the conveyor belt and the sheet metal are not in full contact, thus reducing the risk of the sheet metal cutting the conveyor belt; on the other hand, since the conveyor belt is directly fitted around the outer circumference of the pulley, the tension on the conveyor belt is small, so even if the conveyor belt is cut by the sheet metal, it is not easy to break, thereby effectively improving the stability and reliability of the oiling process.

[0022] 2. The sheet metal oiling device provided in this application is equipped with several rows of pulleys. The risk of the conveyor belts on several pulleys in the same column (with the column as the direction of sheet metal travel) breaking at the same time is extremely low. If the conveyor belts in different columns break, it will not affect the sheet metal conveying. Therefore, the sheet metal oiling device provided in this application has improved operational reliability and can effectively reduce the risk of downtime. Attached Figure Description

[0040] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0041] like Figure 2 As shown, a sheet metal coating device includes a machine body, on which a conveying unit 2 is mounted. Oil spraying units 3 are respectively mounted on the upper and lower sides of the conveying unit 2. The inlets of the oil spraying units 3 are connected to an oil tank 4 via connections. The oil spraying units 3 are existing technology, and their structure will not be described in detail here.

[0042] In one specific embodiment, the fuselage assembly described in this embodiment includes two uprights 11, and an upper crossbeam 12 and a lower crossbeam 13 are arranged sequentially from top to bottom between the two uprights 11.

[0043] like Figure 4 As shown, the conveying assembly 2 includes a drive motor 22 and several parallel drive shafts 21. The drive shafts 21 are rotatably connected to the machine body assembly, and are perpendicular to the conveying direction of the conveying assembly 2. Each drive shaft 21 is connected to the power output end of the drive motor 22, and under the drive of the drive motor 22, the several drive shafts 21 can rotate synchronously. Several pulleys 23 are axially arranged on each drive shaft 21, and a conveyor belt 231 is fitted onto the outer cylindrical surface of each pulley 23.

[0044] In one specific embodiment, the conveying unit 2 in this embodiment includes two drive shafts 21, which are mounted on the lower crossbeam 13 and rotatably connected to the lower crossbeam 13 via bearing assemblies. Each drive shaft 21 is equipped with 15 pulleys 23, which are evenly arranged along the axial direction of the drive shaft 21. A first motor base 14 is provided on the outer side of one of the uprights 11 (with the opposite side of the two uprights 11 as the inner side), and the drive motor 22 is detachably fixed to the first motor base 14. For example, when a person stands on the feed side of the oiling device and faces the oiling device, the drive motor 22 is located on the right side.

[0045] As one specific implementation method, such as Figure 6 As shown, in this embodiment, the right end of the transmission shaft 21 is connected to the power output shaft of the drive motor 22 via a first transmission mechanism 24. The first transmission mechanism 24 includes a driven pulley 241 disposed at the right end of the transmission shaft 21, and a driving pulley 242 disposed on the power output shaft of the drive motor 22. The driving pulley 242 is connected to two driven pulleys 241 via a synchronous belt 243. Tensioning pulleys 244, which press the synchronous belt 243 inward, are respectively disposed on both sides of the synchronous belt 243 between the driving pulley 242 and the driven pulleys 241.

[0046] Furthermore, such as Figure 4 , Figure 5 and Figure 6As shown, the drive shaft 21 includes a working shaft section 211 and a drive shaft section 212. The pulley 23 is mounted on the working shaft section 211. A plurality of drive supports 25 are evenly distributed along the axial direction of the working shaft section 211 on the lower crossbeam 13. The drive supports 25 are detachably fixed to the lower crossbeam 13, and the working shaft section 211 of the drive shaft 21 is rotatably connected to the drive supports 25 via bearing assemblies. One end of the drive shaft section 212 extends through the upright frame 11 to the outer side of the upright frame 11 (with the opposite side of the two upright frames 11 as the inner side), and is rotatably connected to the upright frame 11 via a bearing assembly. The driven pulley 241 is mounted on the drive shaft section 212. The other end of the drive shaft 21 is connected to the working shaft section 211 via a first coupling 213, and the first coupling 213 drives the working shaft section 211 to rotate synchronously.

[0047] When conveyor belt 231 is damaged, first disconnect the new conveyor belt 231, then slip it onto the working shaft section 211 next to the damaged conveyor belt 231. Use a special hot melt gun to connect the conveyor belt 231, and then slip the conveyor belt 231 onto the pulley 23. This method is convenient and quick, reduces downtime, and improves production efficiency.

[0048] Furthermore, the transmission bracket 25 includes a base plate, which is fixedly connected to the lower crossbeam 13 by screws. A vertical plate extending upwards perpendicular to the base plate is provided on the base plate, and the vertical plate has a clearance slot for avoiding the working shaft section 211 of the transmission shaft 21. The working shaft section 211 is rotatably connected to the transmission bracket 25 via a seated bearing 251, and the seated bearing 251 is fixedly connected to the vertical plate by screws.

[0049] Furthermore, such as Figure 8 and Figure 10 As shown, a transition plate 26 is provided above each of the drive shafts 21. The transition plate 26 is detachably fixed to the machine body or transmission bracket 25. The transition plate 26 is provided with clearance openings 261 corresponding to the pulleys 23. The upper end of the conveyor belt 231 protrudes above the transition plate 26 through the clearance openings 261. Preferably, the distance by which the conveyor belt 231 protrudes from the transition plate 26 is 0.1-0.2 times the radius of the conveyor belt 231.

[0050] In one specific embodiment, the transition plate 26 in this embodiment includes a web, with downwardly extending wing plates on both sides of the web. The web and wing plates together form a U-shaped structure with the opening facing downwards, and the pulley 23 is located within the U-shaped structure. The two sides of the web are fixedly connected to the upper end face of the vertical plate of the transmission bracket 25 by screws, and threaded holes are respectively provided on both sides of the clearance notch on the upper end face of the vertical plate.

[0051] By setting the transition plate 26, it can play a good transition role on the one hand, and effectively reduce the risk of the conveyor belt 231 being cut on the other hand.

[0052] In one specific embodiment, the conveyor belt 231 described in this embodiment is a round belt, and the outer cylindrical surface of the pulley 23 is provided with a groove with an arc-shaped cross-section for accommodating the round belt.

[0053] Furthermore, such as Figure 7 , Figure 8 and Figure 10 As shown, a plurality of auxiliary roller assemblies 27 are evenly distributed along the axial direction of two adjacent drive shafts 21. These assemblies provide auxiliary support when passing small sheet metal, preventing the sheet metal from sagging and reducing limitations on workpiece size, making it suitable for smaller sheet metal. For example, eight auxiliary roller assemblies 27 are evenly distributed along the axial direction of two adjacent drive shafts 21.

[0054] In one specific embodiment, the auxiliary roller assembly 27 in this embodiment includes a mounting bracket 271. The mounting bracket 271 includes a first vertical plate 2711 extending in a vertical direction. The first vertical plate 2711 is connected to the wing plate of a transition plate 26 on one side via a bolt assembly. Preferably, the first mounting hole 2712 on the first vertical plate 2711 for accommodating the bolt assembly is an elongated hole extending in a vertical direction, which allows the height of the entire auxiliary roller assembly 27 to be adjusted as needed to match the height of the pulley 23. A horizontal plate 2713 extending perpendicularly to the first vertical plate 2711 towards the transition plate 26 on the other side is provided at the lower end of the first vertical plate 2711. Second vertical plates 2714 extending upward perpendicularly to the horizontal plate 2713 are respectively provided at both ends of the horizontal plate 2713. A mounting shaft 272 is provided between the two second vertical plates 2714, and both ends of the mounting shaft 272 are detachably fixedly connected to the second vertical plates 2714. A plurality of rollers 273 are disposed on the mounting shaft 272 between the two second upright plates 2714. For example, the mounting shaft 272 has two rollers 273, with the two rollers 273 located at opposite ends of the mounting shaft 272. Preferably, the second upright plate 2714 has a second mounting hole 2715 for accommodating the mounting shaft 272. A locking nut 274 is disposed on the outer side of the second upright plate 2714 (with the opposite side of the two second upright plates 2714 as the inner side). The second mounting hole 2715 is an elongated hole extending vertically, allowing for further adjustment of the height of the entire auxiliary roller assembly 27 to match the height of the pulley 23.

[0055] Furthermore, such as Figure 8 and Figure 9 As shown, the conveying assembly 2 also includes a detection shaft 28, and the detection shaft 28 and the drive motor 22 are located on opposite sides of the transmission shaft 21. One end of the detection shaft 28 extends through the upright 11 to the outer side of the upright 11 (with the opposite side of the two uprights 11 as the inner side), and is rotatably connected to the upright 11 via a bearing assembly. The other end of the detection shaft 28 is connected to a working shaft section 211 of the transmission shaft 21 via a second coupling 281. An encoder bracket 291 is provided on the outer side of the upright 11 on which the detection shaft 28 is mounted (with the opposite side of the two uprights 11 as the inner side). The encoder 29 is detachably fixedly connected to the encoder bracket 291, and the detection shaft 28 is connected to the input end of the encoder 29.

[0056] Furthermore, such as Figure 2 and Figure 3As shown, a base 15 is provided at the lower end of the support frame 11, and a traveling wheel 151 is provided on the lower side of the base 15. A second motor mount 16 is provided on the base 15, and a detachable traveling motor 17 is fixedly mounted on the second motor mount 16. The power output shaft of the traveling motor 17 is connected to the traveling wheel 151 on the base 15 on which the traveling motor 17 is mounted through a second transmission mechanism 18.

[0057] By incorporating the traveling wheels 151 and the traveling motor 17 for driving the traveling wheels 151, the entire oiling device can be made capable of offline operation. In actual operation, when the oiling device is not needed, the traveling motor 17 can drive the traveling wheels 151 to move, thereby allowing the oiling device to leave the production line.

[0058] In one specific embodiment, the second motor base 16 in this example includes a base plate 161, which is fixedly connected to the base 15 by screws. A lifting adjustment plate 162 is provided above the base plate 161, and an adjusting screw 163 is provided on the base plate 161. The lower end of the adjusting screw 163 is fixedly connected to the base plate 161, and the upper end of the adjusting screw 163 extends through the lifting adjustment plate 162 to above it. Adjusting nuts 164 are respectively provided on the upper and lower sides of the lifting adjustment plate 162 on the adjusting screw 163. The walking motor 17 is detachably fixed to the lifting adjustment plate 162. During installation, the height of the walking motor 17 can be adjusted by vertically adjusting the height of the lifting adjustment plate 162, thereby placing the second transmission mechanism 18 in a suitable tension state. For example, the second transmission mechanism 18 uses chain drive.

[0059] Furthermore, the machine body is equipped with a protective cover assembly 5, and the conveying assembly 2 is located inside the protective cover assembly 5. The protective cover assembly 5 has a feed port 51 on the feed side of the conveying assembly 2, allowing the sheet metal to pass through, and the protective cover assembly 5 has a discharge port on the discharge side of the conveying assembly 2, allowing the sheet metal to pass through.

[0060] By setting up the protective cover 5, the overall appearance of the equipment can be improved, and the oil mist can be reliably confined within the protective cover 5 to prevent overflow.

[0061] Furthermore, a sheet metal oiling device also includes an oil mist collector 6. The oil mist collector 6 is located outside the protective cover assembly 5, and the oil inlet of the oil mist collector 6 is directly or through a pipeline connected to the interior of the protective cover assembly 5.

[0062] In one specific embodiment, the oil mist collector 6 is located above the fuselage assembly, and the oil mist collector 6 is detachably and fixedly connected to the upper crossbeam 12 of the fuselage assembly. The oil mist collector 6 is existing technology and can be obtained through external purchase; its internal structure will not be described in detail here.

[0063] Furthermore, an oil tank 4 is provided between the two uprights 11 below the lower crossbeam 13, and the oil tank 4 is connected to the oil receiving box 52 at the bottom of the protective cover 5 via an oil return pipe 7.

[0064] During operation, the oil is drawn from the oil tank 4 by the oil pump and pumped to the spraying unit 3, and then sprayed out in an atomized form from the nozzle of the spraying unit 3, which is evenly sprayed onto the sheet metal. Excess oil will collect in the oil collection box 52 along the inner wall of the protective cover unit 5, and finally flow back to the oil tank 4 through the return oil pipe 7.

[0065] Other embodiments obtained by those skilled in the art based on the embodiments provided in this application by combining, splitting, or reorganizing the embodiments of this application do not exceed the protection scope of this application.
