Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and more specifically, to a polishing equipment for fine polishing of metal window frame surfaces. Background Technology

[0002] In the modern construction industry, as people's requirements for building quality and aesthetics continue to increase, the surface quality of metal window frames is receiving more and more attention. In the existing door and window frame grinding process using workbenches and grinding equipment, the workbench lacks components to limit the door and window frame. Therefore, the door and window frame is prone to deviation during the conveying and grinding process, making it impossible for the grinding equipment to grind it stably. The current method of manually supporting the door and window frame to limit it not only reduces the convenience of grinding the door and window frame, but also occupies more time and energy for the user, thus making it inconvenient for the user.

[0003] To address the aforementioned issues, patent document CN222327749U discloses a grinding structure for processing door and window frames, comprising a worktable, a processing plate, two guiding mechanisms, a transmission mechanism, and a polishing mechanism. The processing plate is located on top of the worktable, and the two guiding mechanisms are located on the front and rear sides of the worktable, respectively. This solves the problem that during the grinding process of door and window frames using a worktable and grinding equipment, the worktable lacks components to limit the movement of the door and window frames. Such limiting methods not only reduce the convenience of grinding door and window frames but also consume a significant amount of time and effort for the user, making it inconvenient for the user.

[0004] However, it still has some shortcomings in actual use. For example, after a single operation of the above-mentioned grinding structure, the door and window frames that require fine grinding need to be transferred to a more refined grinding device for further grinding, which makes the grinding mechanism less practical and greatly reduces the working efficiency and quality of the grinding equipment to a certain extent. In order to solve the shortcomings of the existing technology, we propose a grinding device for fine polishing of metal window frame surfaces. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a grinding device for fine polishing of metal window frame surfaces. This solves the problem that after a single operation of the above-mentioned grinding structure, the door and window frames requiring fine grinding need to be transferred to a more refined grinding device for further grinding, which results in poor practicality of the grinding mechanism and greatly reduces the working efficiency and quality of the grinding device to a certain extent.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a polishing device for fine polishing of metal window frame surface, including a base, a double polishing component is provided on the upper side of the middle part of the base, a clamping and moving component is provided on the lower side of the double polishing component, a roller is rotatably connected to the upper inner wall of the base, and a plate is attached to the outer surface of the roller.

[0007] The dual grinding assembly includes two brackets, with an H-shaped mounting bracket between them. A first grinding roller is rotatably connected to the inner surface of one side of the H-shaped mounting bracket, and a second grinding roller is rotatably connected to the inner surface of the other side of the H-shaped mounting bracket. A first motor is fixedly mounted at one end of both the first and second grinding rollers. Two fixed shafts are fixedly mounted on the outer surfaces of both sides of the H-shaped mounting bracket. A first gear is fixedly mounted at one end of one of the fixed shafts. A toothed plate meshes with the outer surface of the first gear, and a cylinder is fixedly mounted at one end of the toothed plate.

[0008] The two brackets are symmetrically fixedly installed on the outer surfaces of both sides of the base, the first motor is fixedly installed on the outer surface of one side of the H-shaped mounting bracket, the two fixed shafts are rotatably connected to the inner walls of the two brackets respectively, the toothed plate slides on the inner wall of the bracket, and the cylinder is fixedly installed on the upper outer surface of the bracket.

[0009] The clamping and moving assembly includes a second motor. An L-shaped fixing frame is symmetrically fixedly mounted on the side of the base. A second gear is fixedly mounted on the outer surface of the output end of the second motor. A shaped gear meshes with the outer surface of the second gear. A guide rail is fixedly mounted on one end of the shaped gear. A limit rod is fixedly mounted on one side of the outer surface of the guide rail. A limit frame is slidably mounted on the outer wall of the limit rod. A threaded screw is rotatably connected to the inner wall of the guide rail. A clamping block is uniformly threaded onto the outer surface of the threaded screw. A third motor is fixedly mounted on one end of the threaded screw. The L-shaped fixing frame is fixedly mounted on the lower outer surface of the base. The cylindrical outer wall of the shaped gear and the limit rod slide on the inner wall of the base. The limit frame is fixedly mounted on one side of the outer surface of the base. The clamping block slides on one side of the outer wall of the guide rail. The third motor is fixedly mounted on one end of the outer surface of the guide rail.

[0010] The grinding precision of the first grinding roller is greater than that of the second grinding roller.

[0011] The guide rail frame has a gap between its bottom and the top of the base, and the height of the gap is equal to the distance between the highest point of the roller and the top of the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a dual-grinding assembly, including a support frame. Two first motors are simultaneously activated, driving the first and second grinding rollers to rotate. The second grinding roller performs the first grinding and polishing of the material. After this, a starting cylinder pushes a toothed plate downwards, causing the toothed plate to rotate and thus rotating the H-shaped mounting frame. This allows the first grinding roller to perform a second grinding and polishing of the material. This structure, using a starting cylinder to rotate the H-shaped mounting frame, enables the replacement of the first and second grinding rollers, facilitating double grinding and polishing of the material. This results in a finer polished surface, significantly increasing the equipment's practicality and improving the efficiency and quality of the grinding and polishing equipment.

[0014] This invention utilizes a clamping and moving assembly, including a second motor. First, the plate is placed on the upper outer surface of the base. Then, the second motor is activated, driving a second gear to rotate. The rotation of the second gear causes two irregularly shaped gear frames to slide relative to each other, thereby causing two guide rail frames to slide relative to each other. This allows the clamping block to clamp the outer surfaces of both sides of the plate. Next, a third motor is activated, driving a threaded screw to rotate. The rotation of the threaded screw causes the clamping block to move horizontally, further causing the plate to slide on the outer surface of the roller. After the first grinding and polishing is completed, the third motor is activated again to reverse and reset the plate. During the reset process, the second grinding and polishing is completed. Using this structure, by activating the second and third motors, not only is clamping and moving of different plates achieved, but repeated clamping of plates is also avoided, further improving the working efficiency of the grinding and polishing device.

A toothed plate 28 meshes with the outer surface of the first gear 27. A cylinder 29 is fixedly mounted at one end of the toothed plate 28.

[0023] Two brackets 21 are symmetrically fixedly installed on the outer surfaces of both sides of the base 1, the first motor 25 is fixedly installed on the outer surface of one side of the H-shaped mounting bracket 22, two fixed shafts 26 are rotatably connected to the inner walls of the two brackets 21 respectively, the toothed plate 28 slides on the inner wall of the bracket 21, and the cylinder 29 is fixedly installed on the upper outer surface of the bracket 21.

[0024] By starting the cylinder 29 to drive the H-shaped mounting bracket 22 to rotate, the positions of the first grinding roller 23 and the second grinding roller 24 can be changed, which facilitates double grinding and polishing of the plate 5, thereby achieving a finer polished surface, greatly increasing the practicality of the equipment, and thus improving the working efficiency and quality of the grinding and polishing equipment.

[0025] The clamping and moving assembly 3 includes a second motor 31. An L-shaped fixing bracket 32 ​​is symmetrically fixedly mounted on the side of the base 1. A second gear 33 is fixedly mounted on the outer surface of the output end of the second motor 31. A shaped gear frame 34 meshes with the outer surface of the second gear 33. A guide rail frame 35 is fixedly mounted on one end of the shaped gear frame 34. A limit rod 36 is fixedly mounted on one outer surface of the guide rail frame 35. A limit bracket 37 is slidably mounted on the outer wall of the limit rod 36. A threaded wire is rotatably connected to the inner wall of the guide rail frame 35. The outer surface of the threaded rod 38 is uniformly threaded with a clamping block 39. A third motor 311 is fixedly installed at one end of the threaded rod 38. The L-shaped fixing frame 32 is fixedly installed on the lower outer surface of the base 1.

[0030] First, the plate 5 is placed on the upper outer surface of the base 1. Then, the second motor 31 is started to drive the second gear 33 to rotate. The rotation of the second gear 33 causes the two irregularly shaped gear frames 34 to slide relative to each other, thereby causing the two guide rail frames 35 to slide relative to each other, so that the clamping block 39 clamps the outer surfaces of both sides of the plate 5. Then, the third motor 311 is started to drive the threaded screw 38 to rotate. The rotation of the threaded screw 38 causes the clamping block 39 to move horizontally, thereby causing the plate 5 to slide on the outer surface of the roller 4. At the same time, the two first motors 25 are started to drive the first grinding roller 23 and the second grinding roller 24 to rotate simultaneously. Then, the second grinding roller 24 performs the first grinding and polishing on the plate 5. After the first grinding and polishing is completed, the cylinder 29 is started to push the toothed plate 28 to slide downward. The sliding of the toothed plate 28 drives the first gear 27 to rotate, thereby driving the H-shaped mounting bracket 22 to rotate, so that the first grinding roller 23 and the second grinding roller 24 exchange positions. At this time, the third motor 311 is started again to reverse and drive the plate 5 to reset. The second grinding and polishing is completed during the reset process.
