Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion coating polishing technology, and in particular to an anti-corrosion coating polishing device. Background Technology

[0002] In industrial production, the surface treatment of welded sheet metal is crucial, especially the grinding and polishing process for anti-corrosion coatings. Initially, manual grinding was primarily used to remove impurities such as weld slag and oxides generated during welding to ensure the accuracy and reliability of weld inspection. With technological advancements, various mechanical grinding equipment, such as angle grinders, have emerged, improving grinding efficiency and quality to some extent. However, these devices still have limitations when grinding the anti-corrosion coating at the weld seams of sheet metal, prompting the technology to continuously evolve towards automation and higher efficiency to meet the growing demands of industrial production.

[0003] Currently, the technology for grinding and polishing anti-corrosion coatings has made some progress. Various grinding equipment and processes are available on the market, capable of treating the surface of sheet materials to a certain extent. These devices typically possess some automation capabilities, which can improve grinding efficiency to some extent. However, in practical applications, especially when grinding the anti-corrosion coating at the weld seams of sheet materials, some problems still exist. For example, most equipment requires manual flipping and re-fixing of the sheet material after grinding one side to allow for grinding of the other side. This process is not only time-consuming and labor-intensive but also increases the workload of workers, severely impacting the overall grinding efficiency of the sheet material.

[0004] It is evident that traditional sanding processes require a significant amount of manpower and time to flip and fix the anti-corrosion coating on the board, which affects the sanding precision and quality. Furthermore, traditional sanding processes are usually performed manually by technicians, making it impossible to meet the needs of large-scale and high-efficiency production and achieve industrialized operation.

[0047] This utility model proposes a device for polishing anti-corrosion coatings.

[0048] Please see Figures 1 to 6 In one embodiment of this utility model, the anti-corrosion coating polishing device includes a frame 100, a fixing frame 200, a plate fixing mechanism 300, and a polishing mechanism 400.

[0050] In one embodiment, the plate fixing mechanism 300 includes a bearing ring 310 and a plurality of locking components 340. The bearing ring 310 is installed in the grinding space 110 and is rotatably engaged with the frame 100. A fixing cavity 320 for fixing the plate to be ground is formed in the bearing ring 310. A plurality of locking holes 330 are formed on the bearing ring 310 at intervals along the circumference.

Each locking component 340 is installed in the fixing cavity 320 and each locking component 340 can movably pass through the corresponding locking hole 330 and extend to the outside of the bearing ring 310. All locking components 340 cooperate with each other to fix the plate to be ground in the fixing cavity 320.

[0051] In one embodiment, the bearing ring 310 is a rectangular ring with a rectangular vertical projection plane, and two opposite sides of the rectangular ring are locking sides, with locking holes 330 spaced circumferentially on the locking sides.

[0052] In one embodiment, the bearing ring 310 includes an outer ring body 311, an inner ring body 313, two guide rods 315, and two linkage blocks 317. The outer ring body 311 is rotatably engaged with the frame 100.

The inner ring body 313 is spaced within the inner cavity of the outer ring body 311, and the inner cavity of the inner ring body 313 forms a fixed cavity 320. A movement space 314 is formed between the inner ring body 313 and the outer ring body 311. Locking holes 330 are circumferentially spaced within the inner ring body 313. On the mating side, each locking component 340 passes through the corresponding locking hole 330 and extends into the movement space 314. Two guide rods 315 are set one-to-one with two mounting holes 312, and one of the guide rods 315 is a threaded rod. Two unlocking plates 316 are movably set in the movement space 314, and each unlocking plate 316 corresponds to a locking side. The locking components 340 passing through the same locking side are connected to the unlocking plate 316 on the corresponding side. Two linkage blocks 317 are slidably connected to the guide rods 315, and each linkage block 317 is connected to an unlocking plate 316.

[0053] In one embodiment, the locking assembly 340 includes a locking rod 341, a locking block 342, a patch 343, and a resilient reset member 344. One end of the locking rod 341 movably passes through the lock hole 330 and is connected to the unlocking plate 316. The other end of the locking rod 341 extends into the fixing cavity 320. The locking block 342 is installed at the end of the locking rod 341 that extends into the fixing cavity 320. The patch 343 is installed at the end of the locking block 342 that is away from the locking rod 341. The patch 343 is arranged in a comb-like shape. The resilient reset member 344 is sleeved on the outer periphery of the locking rod 341 and is located between the unlocking plate 316 and the inner ring body 313.

[0054] In one embodiment, the locking block 342 is a triangular structure with its hypotenuse facing upwards.

[0055] In one embodiment, a drive unit 350 is further provided on the frame 100, and the output end of the drive unit 350 is rotatably engaged with the outer ring body 311. It should be particularly and explicitly stated that the drive unit 350 exemplified in this embodiment is preferably a drive motor.

[0056] In one embodiment, a support plate 360 ​​is provided at each corner of the inner ring 313, and a blocking protrusion 370 is provided on the top of each support plate 360.

[0057] In one embodiment, the grinding mechanism 400 includes an electric telescopic rod 410 and a grinding machine 420. The electric telescopic rod 410 is mounted on the fixed frame 200 and is located above the grinding space 110. The grinding machine 420 is mounted on the electric telescopic rod 410 and is mounted at the bottom end of the electric telescopic rod 410. The electric telescopic rod 410 can drive the grinding machine 420 to descend and grind the material to be ground placed in the grinding space 110.

[0058] In one embodiment, a first guide rail 500 extending in a first direction is provided on the fixing frame 200, a first sliding member is slidably fitted on the first guide rail 500, a second guide rail 600 extending in a second direction is mounted on the first sliding member, and the grinding mechanism 400 is slidably mounted on the second guide rail 600.

[0059] In this embodiment, the first direction of the example is the X-axis extension direction, and the second direction of the example is the Y-axis extension direction.

[0060] A fixed frame 200 is fixedly connected to the top of the frame 100. An XY axis moving platform is provided on the inner surface of the fixed frame 200. An electric telescopic rod 410 is provided on the XY axis moving platform. A grinder 420 is fixedly connected to the other end of the electric telescopic rod 410. A bearing ring 310 is rotatably connected to the inner surface of the frame 100. The bearing ring 310 is hollow inside. A bearing plate 360 ​​is fixedly connected to the inner surface of the bearing ring 310. A motor is fixedly connected to the outer wall of the frame 100. The main shaft of the motor passes through the frame 100 and is fixedly connected to the rotating shaft of the bearing ring 310. A fixing mechanism for fixing the plate is provided inside the bearing ring 310.

[0061] The fixing mechanism includes multiple sets of locking rods 341 disposed inside the bearing ring 310. Symmetrically arranged unlocking plates 316 are disposed inside the hollow portion of the bearing ring 310. One end of each locking rod 341 passes through the bearing ring 310 and the unlocking plate 316 into the interior of the bearing ring 310. A baffle plate is fixedly connected to the end of the locking rod 341 that passes through the unlocking plate 316. A pressure spring is fixedly connected to the outer wall of the locking rod 341 extending into the interior of the bearing ring 310. The other end of the pressure spring is fixedly connected to the outer wall of the unlocking plate 316. Locking blocks 342 are fixedly connected to the ends of the locking rods 341 away from the unlocking plate 316. The locking blocks 342 have a triangular structure. A limit rod and an adjusting rod are rotatably connected to the inner wall of the hollow portion of the bearing ring 310. Symmetrically arranged linkage blocks 317 are slidably connected to the limit rods. The linkage blocks 317 are respectively fixed to the ends of the unlocking plates 316. The adjusting rod has symmetrically arranged threaded grooves, and the linkage block 317 is passed through by the adjusting rod and threadedly connected to the threaded grooves. When the plate is placed on the bearing plate 360, the locking block 342 can automatically fix the plate. The XY axis moving platform can drive the electric telescopic rod 410 to move. As the electric telescopic rod 410 moves and extends and retracts, it drives the grinding machine 420 to grind the anti-corrosion coating on the surface of the plate. The motor can automatically flip the plate, so that the grinding machine 420 can grind the reverse side of the plate. After grinding, the plate 316 can be unlocked by rotating the adjusting rod, so that the plate can be taken out and replaced. This reduces the labor intensity and efficiency of the workers when flipping the plate and increases the grinding efficiency of the anti-corrosion coating on the surface of the plate.

[0062] Furthermore, one end of the adjusting rod passes through the bearing ring 310 to its outside and is fixedly connected to an adjusting plate; by setting the adjusting plate, it is more convenient for the staff to rotate the adjusting rod, making the process of unlocking the plate 316 material more convenient.

[0063] Furthermore, the inner wall of the bearing ring 310 is fixedly connected with symmetrically arranged upper abutment plates, and the inner wall of the frame 100 is fixedly connected with a lower abutment plate. When the upper abutment plate rotates with the bearing ring 310, the upper abutment plate can abut against the lower abutment plate. Through the abutment plates, after the bearing ring 310 rotates and flips the plate, the upper abutment plate and the lower abutment plate can abut against each other, and the lower abutment plate can support the bearing ring 310 through the upper abutment plate, thereby increasing the stability when polishing the anti-corrosion coating on the surface of the plate.

[0064] Furthermore, right-angle stops are fixedly connected to each of the 360° support plates; the right-angle stops can block the plate and prevent it from sliding during the sanding process.

[0065] Furthermore, the vertical arrangement of each set of locking rods 341 ensures that when bent or uneven plates (which are subjected to tensile, compressive, or cutting forces during production and processing, or are subjected to stress during welding, causing them to bend) are placed on the support plate 360, the bent or uneven parts of the plates will push against the locking blocks 342 on the locking rods 341 at different positions in each set of locking rods 341. This allows the locking blocks 342 at different positions to block and fix the bent or uneven parts of the plates, thereby increasing the stability of the plates during grinding and flipping.

[0066] Furthermore, a rubber patch 343 is fixedly connected to the end of the locking block 342 away from the locking rod 341. The end of the patch 343 away from the locking block 342 has a comb-tooth structure. When the locking block 342 is squeezed by the plate, the patch 343 will also be squeezed by the plate and begin to bend. When the plate is placed on the support plate 360, during the process of the locking block 342 resetting under the elastic force of the pressure spring, the patch 343 is squeezed and bent by the plate. Therefore, as the locking block 342 moves, it pushes the patch 343, so that the patch 343 bends and fits against the surface of the plate. This allows the friction generated by the comb-tooth structure at the end of the patch 343 against the plate to limit the plate, thereby reducing the probability of the plate shifting due to contact with the grinder 420 during grinding. In addition, the comb-tooth structure at the end of the patch 343 can distribute the pressure evenly on the surface of the plate, which can effectively increase the friction with the surface of the plate.

[0067] Working principle: This embodiment provides a device for quickly polishing the anti-corrosion coating during weld inspection. When the plate to be polished is placed on the support plate 360, the plate will push the locking block 342, causing the locking block 342 to push the locking rod 341 into the support ring 310. The locking rod 341 will then compress the pressure spring. After the plate is placed on the support plate 360, the locking block 342 will begin to reset under the force of the pressure spring. This will cause the bottom of the locking block 342 to block the top of the plate, thus fixing the plate. The XY axis moving platform can drive the electric telescopic rod 410 to move. As the electric telescopic rod 410 moves and extends and retracts, it drives the polishing machine 420 to polish the anti-corrosion coating on the surface of the plate.

[0068] When the other side of the board needs to be polished after the first polishing is completed, the motor drives the bearing ring 310 to rotate, causing the bearing ring 310 to flip the board. The locking block 342 then fixes the board in place, preventing it from falling off. After the other side of the board is polished, the adjusting rod can be rotated to move the threaded grooves and the linkage blocks 317 away from each other. This causes the linkage blocks 317 to move the unlocking plate 316, and the baffle moves the locking rod 341. This causes the locking rod 341 to move the locking block 342, which then stops fixing the board. At this point, the board can be removed, and the adjusting rod can be flipped. Similarly, the locking block 342 is reset to prepare for the next board fixing.

[0069] Therefore, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. The above description is merely an exemplary embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
