Description
Technical Field
[0001] This utility model relates to the technical field of aluminum alloy door and window processing equipment, specifically to an edge and corner passivation treatment device for aluminum alloy door and window processing. Background Technology
[0002] In the production and processing of aluminum alloy doors and windows, edge and corner passivation is a core process to ensure product quality and service life. However, traditional aluminum alloy door and window processing equipment often uses fixed clamping fixtures in the clamping and fixing stage. This design lacks flexibility and cannot be precisely adjusted according to the different sizes of aluminum alloy doors and windows, resulting in poor clamping stability. During processing, doors and windows are prone to shaking or displacement, which not only affects processing accuracy but also directly reduces the effectiveness of edge and corner passivation.
[0003] Existing passivation equipment has significant limitations in adjusting the grinding range. It typically only grinds aluminum alloy doors and windows of specific sizes, requiring frequent replacement of grinding components or readjustment of the equipment structure when dealing with doors and windows of different sizes or with different passivation requirements. This not only increases operational complexity and labor intensity but also significantly reduces production efficiency. For example, for larger doors and windows, the equipment may not be able to effectively adjust the grinding range, resulting in insufficient grinding; while for smaller doors and windows, over-grinding may occur, affecting product quality.
[0004] Furthermore, existing passivation equipment suffers from numerous inconveniences in its processing flow. Typically, the equipment can only passivate a single aluminum alloy door or window. After processing, the treated door or window must be disassembled and removed, and other doors and windows from the same batch must be placed on top for fixation and positioning. The equipment is then restarted for further grinding and passivation. This repetitive operation is not only cumbersome but also significantly impacts production efficiency, making it difficult to meet the demands of modern large-scale production.
[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing edge passivation equipment. Utility Model Content
[0006] This utility model addresses the problem that existing technical solutions are too simplistic by providing a significantly different solution for the edge passivation treatment equipment used in aluminum alloy door and window processing, thus resolving the issues raised in the background section.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a corner passivation treatment device for aluminum alloy door and window processing, comprising a conveying mechanism, wherein clamping structures for limiting the aluminum alloy door and window are installed at equal intervals on the conveyor belt of the conveying mechanism, a gantry frame is installed on the conveying mechanism, and a width adjustment structure is provided on each side of the conveying mechanism inside the gantry frame, and a plate is connected to each end of each width adjustment structure, and a grinding belt assembly for grinding and passivating the corners of the aluminum alloy door and window is installed on each plate, and a length adjustment structure for controlling the distance between the grinding belt assembly and the conveying mechanism is installed between the top and sides of the gantry frame.
[0008] Preferably, the clamping structure includes a bearing plate, a clamping screw, and a clamping plate. Bearing plates are installed at equal intervals on the conveyor belt of the conveying mechanism, and a clamping screw is threaded to each side of each bearing plate. The clamping screw is rotatably connected to a clamping plate for fitting aluminum alloy doors and windows at the inner end of the bearing plate.
[0009] Preferably, the support plate is configured with a concave structure.
[0010] Preferably, the width adjustment structure includes a box body, a control screw, and a sliding sleeve. A control screw is rotatably connected to each box body, and a sliding sleeve is fitted at each end of the control screw in the area inside the box body. Each sliding sleeve is connected to a plate through the top of the box body.
[0011] Preferably, the threads of each control screw located at both ends of the housing area have opposite helical directions, and the control screw and the sliding sleeve are threadedly connected.
[0012] Preferably, the length adjustment structure includes a connecting box, a connecting piston rod, a hose, a control box, a control piston rod, a groove, an adjusting screw, an electric push rod, a nut, an annular groove, and a limiting block. A connecting box is installed on each side of the gantry, and each connecting box contains a connecting piston rod. The end of each connecting piston rod penetrates the inner wall of the gantry and is connected to a housing. A hose is connected to the outer wall of each connecting box on the side away from the conveying mechanism, and each hose is connected to the control box. The control box is installed on the top of the gantry. The control box contains a control piston rod, and a groove is formed at the upper end of the control piston rod penetrating the top of the control box. An adjusting screw is connected within the groove. An electric push rod is connected to the end of the adjusting screw, and the electric push rod is installed on the top of the gantry via a mounting bracket. A nut is threaded onto the adjusting screw, and an annular groove is formed at the bottom of the nut. Several limiting blocks are slidably engaged within the annular groove at equal angles, and the limiting blocks are fixedly connected to the upper end of the control piston rod.
[0013] Preferably, the polishing belt assembly is mounted on the plate in an inclined manner, and the two sets of polishing belt assemblies on each box have opposite inclination directions.
[0014] Compared with existing technologies, the advantages of this invention are as follows: This aluminum alloy door and window processing edge passivation equipment allows the aluminum alloy door and window to be placed on a support plate. Rotating the clamping screw pushes the clamping plate to contact and clamp the two sides of the aluminum alloy door and window for positioning and fixation. This clamping method is not only simple and quick to operate, but also allows for flexible adjustment according to different sizes of aluminum alloy doors and windows, ensuring the doors and windows remain stable throughout the processing.
[0015] The ingeniously designed width and length adjustment structures allow for flexible adjustment based on the size and passivation requirements of aluminum alloy doors and windows, greatly enhancing the equipment's versatility. The width adjustment structure uses a rotating control screw with opposite thread directions at both ends to move the sliding sleeve, which in turn moves the plate and its grinding belt assembly closer or further apart, accommodating the grinding needs of aluminum alloy doors and windows of varying widths. The length adjustment structure, through the coordinated action of a nut, adjusting screw, and electric push rod, controls the distance between the grinding belt assembly and the conveying mechanism to meet different passivation depth requirements. This flexible and adjustable grinding range allows the equipment to handle aluminum alloy doors and windows of various sizes and passivation needs without frequent equipment changes or complex adjustments, improving the equipment's versatility and production efficiency.
[0016] During the polishing process, the polishing belt assembly is installed on the plate in an inclined manner, and the two sets of polishing belt assemblies on each box are inclined in opposite directions. This unique installation method can ensure that the polishing belt has more sufficient and uniform contact with the corners of the aluminum alloy doors and windows, effectively improving the polishing and passivation effect.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-8 This utility model provides a technical solution: an edge passivation treatment device for aluminum alloy door and window processing, including a conveying mechanism 1, a clamping structure 2, a bearing plate 201, a clamping screw 202, a clamping plate 203, a gantry frame 3, a width adjustment structure 4, a box 401, a control screw 402, a sliding sleeve 403, a plate 5, a grinding belt assembly 6, a length adjustment structure 7, a connecting box 701, a connecting piston rod 702, a hose 703, a control box 704, a control piston rod 705, a groove 706, an adjusting screw 707, an electric push rod 708, and a nut 709. The conveyor belt of the conveyor mechanism 1 is equipped with clamping structures 2 for limiting the aluminum alloy doors and windows at equal intervals. The conveyor mechanism 1 is equipped with a gantry frame 3, and a width adjustment structure 4 is provided on each side of the conveyor mechanism 1 inside the gantry frame 3. Each width adjustment structure 4 is connected to a plate 5 at both ends, and a grinding belt assembly 6 for grinding and blunting the edges and corners of the aluminum alloy doors and windows is installed on each plate 5. A length adjustment structure 7 for controlling the distance between the grinding belt assembly 6 and the conveyor mechanism 1 is installed between the top and sides of the gantry frame 3.
[0028] The clamping structure 2 includes a bearing plate 201, a clamping screw 202, and a clamping plate 203. The bearing plates 201 are installed at equal intervals on the conveyor belt of the conveying mechanism 1, and each bearing plate 201 is threaded to a clamping screw 202 on both sides. The clamping screw 202 is rotatably connected to the clamping plate 203 for fitting aluminum alloy doors and windows at the inner end of the bearing plate 201.
[0029] The support plate 201 is designed with a concave structure.
[0030] The width adjustment structure 4 includes a box body 401, a control screw 402, and a sliding sleeve 403. Each box body 401 is rotatably connected to a control screw 402, and each control screw 402 is fitted with a sliding sleeve 403 at both ends of the area inside the box body 401. Each sliding sleeve 403 has a plate 5 connected to the top of the box body 401 through its end.
[0031] The threads of each control screw 402 located at both ends of the inner region of the housing 401 are in opposite directions, and the control screw 402 and the sliding sleeve 403 are threadedly connected.
[0032] The length adjustment structure 7 includes a connecting box 701, a connecting piston rod 702, a hose 703, a control box 704, a control piston rod 705, a groove 706, an adjusting screw 707, an electric push rod 708, a nut 709, an annular groove 710, and a limit block 711. A connecting box 701 is installed on each side of the gantry 3, and each connecting box 701 contains a connecting piston rod 702. The end of each connecting piston rod 702 penetrates the inner wall of the gantry 3 and is connected to a housing 401. A hose 703 is connected to the outer wall of each connecting box 701 on the side away from the conveying mechanism 1, and each hose 703 is connected to the control box 704. The control box 704 is installed on the top of the gantry 3 and contains a control... The piston rod 705 has a groove 706 at the top end of the control box 704, and an adjusting screw 707 is connected inside the groove 706. An electric push rod 708 is connected to the end of the adjusting screw 707, and the electric push rod 708 is installed on the top of the gantry frame 3 through a mounting bracket. A nut 709 is threaded onto the adjusting screw 707, and an annular groove 710 is opened at the bottom of the nut 709. Several limit blocks 711 are slidably connected at equal angles in the annular groove 710, and the limit blocks 711 are fixedly connected to the upper end of the control piston rod 705. The adjusting screw 707 and the electric push rod 708 are fixedly connected, while the adjusting screw 707 and the control piston rod 705 are slidably connected through a snap-fit structure. Because there is a threaded connection between the outer wall of the adjusting screw 707 and the nut 709, when the nut 709 rotates, it is constrained by the annular groove 710 and the limiting block 711, but this constraint does not affect the normal rotation of the nut 709. On the contrary, the rotation of the nut 709 will drive the piston rod 705 to move upward or downward along the axial direction of the adjusting screw 707 through the thread action, and the oil inside the control box 704 is not full.
[0033] The sanding belt assembly 6 is mounted on the plate 5 in an inclined manner, and the two sets of sanding belt assemblies 6 on each box 401 have opposite inclination directions.
[0034] Working principle: According to Figure 1 As shown, the aluminum alloy door and window to be passivated is first placed on the carrier plate 201, with the head and tail of the aluminum alloy door and window facing the two sides of the conveying mechanism 1. Then, the clamping screw 202 is rotated and moved on the carrier plate 201, pushing the two clamping plates 203 to contact the two sides of the aluminum alloy door and window respectively for limiting and fixing.
[0035] Based on the size parameters of the aluminum alloy doors and windows, and the degree of wear to be ground and dulled, the nut 709 is pre-rotated. Under the limiting constraints of the annular groove 710 and the limiting block 711, the adjusting screw 707 can be extended into or moved out of the groove 706 by rotating the nut 709. This process achieves precise adjustment of the total length of the control piston rod 705 and the adjusting screw 707, thereby meeting different working requirements. The rotation of the nut 709 drives the threaded adjusting screw 707 to move into or out of the groove 706. If the size of the aluminum alloy doors and windows is larger, and the degree of wear to be ground and dulled is greater, then the adjusting screw 707 moves deeper into the groove 706. If the size of the aluminum alloy doors and windows is smaller, then the opposite is true.
[0036] Meanwhile, based on the size parameters of the aluminum alloy doors and windows, the control screw 402 is pre-rotated, and the two ends of the screw located in the inner area of the housing 401 are spiraled in opposite directions, so that the sliding sleeves 403 connected to the two ends by threads move closer to each other or further away from each other. For example, if the size of the aluminum alloy doors and windows is larger, then the two sliding sleeves 403 connected by threads on the control screw 402 will drive the plate 5 and the grinding belt assembly 6 on it to move further away from each other. If the size of the aluminum alloy doors and windows is smaller, then the opposite is true.
[0037] The conveying mechanism 1 is started for transmission. When the aluminum alloy door and window clamped and limited on the bearing plate 201 moves into the gantry 3, the electric push rod 708 is started, pushing the adjusting screw 707 and the control piston rod 705 to move into the control box 704. The hydraulic oil in the control box 704 is squeezed into the hose 703 and then transported to the connecting box 701 through the hose 703. This causes the connecting piston rod 702 in the connecting box 701 to move outward. The connecting piston rod 702 pushes the box 401 closer to the head and tail ends of the aluminum alloy door and window, so that the grinding belt assembly 6 on the plate 5 grinds and passivates the edges and corners of the aluminum alloy door and window. The stroke of the electric push rod 708 remains consistent. With the length control of the control piston rod 705 and the adjusting screw 707, different injection volumes of oil are achieved. This is the working principle of the edge passivation treatment equipment for aluminum alloy door and window processing.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
