Description

Technical Field

[0001] The utility model relates to the technical field of corner assembly machines, in particular to a corner assembly machine for processing aluminum alloy doors and windows. Background Art

[0002] Aluminum alloy doors and windows are widely used in architectural decoration due to their lightweight, corrosion-resistant, aesthetically pleasing, and durable properties. Cornering is a critical step in aluminum alloy door and window processing, directly impacting their structural stability, sealing, and overall aesthetics. The aluminum alloy door and window cornering machine, the core equipment for this process, precisely cuts and joins the corners of door and window profiles using cutting tools, creating secure right-angle connections.

[0003] Existing angle-assembling machines for processing aluminum alloy doors and windows have obvious limitations in the use of tools: since door and window profiles of different specifications and models require matching angle-assembling tools of different sizes or types, traditional angle-assembling machines mostly use manual tool replacement, which requires manual removal of old tools, installation of new tools and recalibration after stopping the machine. This is not only cumbersome and time-consuming, affecting production efficiency, but also manual calibration makes it difficult to ensure tool positioning accuracy, which can easily lead to unstable angle-assembling quality; although some improved equipment has attempted to achieve semi-automatic tool change, most of them are single-tool independent control, and cannot achieve synchronous switching of two symmetrical tools. During the tool change process, tool positioning deviations on both sides are prone to occur, further affecting the symmetry and accuracy of the angle assembly. Therefore, we disclose an aluminum alloy door and window processing angle-assembling machine to meet people's needs. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 - Figure 5 , the embodiment provided by the utility model:

[0027] A machine for processing and cornering aluminum alloy doors and windows comprises a workbench 1. A limiting mechanism for limiting the position of door and window profiles is installed on the top of the workbench 1.

[0028] like Figure 1 As shown, the limiting mechanism includes a groove defined at the top of the workbench 1, within which a front cylinder 9 is mounted. A triangular clamping plate 10 is connected to the movable end of the front cylinder 9. A V-shaped baffle 16 is fixedly mounted on the top of the workbench 1, with the triangular clamping plate 10 positioned opposite the V-shaped baffle 16. When the front cylinder 9 is activated, the movable end of the front cylinder 9 pushes the triangular clamping plate 10 toward the profile. The triangular clamping plate 10 and the V-shaped baffle 16 cooperate to securely hold the door and window profile between them, achieving precise positioning. The cross-section of the triangular clamping plate 10 is an isosceles trapezoid, with the two sides of the V-shaped baffle 16 perpendicular.

[0029] A cavity 17 is provided on the workbench 1, and two guide holes 18 are provided on the top wall of the cavity 17. Guide blocks 3 are slidably installed in the two guide holes 18, and tool head seats 30 are rotatably installed on the tops of the two guide blocks 3. Multiple cutting tools 29 are installed on the outer sides of the two tool head seats 30, and a moving mechanism for moving the two guide blocks 3 is installed on the top of the workbench 1.

[0030] In this embodiment, the cutter head seat 30 is cylindrical, and a plurality of mounting grooves are provided around the side of the cutter head seat 30. The mounting grooves are arranged along the axial direction of the cutter head seat 30. One end of the cutter 29 extends into the cutter head seat 30 and is tightened by a bolt threaded on the cutter head seat 30. The cutters 29 on the two cutter head seats 30 are arranged opposite each other.

[0031] like Figure 1As shown, the moving mechanism includes a rear cylinder 4 fixedly mounted on the side of the workbench 1. The movable end of the rear cylinder 4 is fixedly connected to a U-shaped plate 5. The top of the U-shaped plate 5 is provided with two inclined slots 6. The sides of the two guide blocks 3 that are away from each other are fixedly mounted with L-shaped slides 7. The bottoms of the two L-shaped slides 7 are respectively slidably mounted within the two inclined slots 6. When the rear cylinder 4 is activated, the movable end of the rear cylinder 4 is stretched outward, driving the U-shaped plate 5 connected thereto to move synchronously. As the U-shaped plate 5 moves, the inclined slots 6 on both sides of the rear cylinder 4 guide the two L-shaped slides 7, prompting them to move toward each other along a preset trajectory, thereby driving the two guide blocks 3 closer to each other, ultimately causing the two tool holders 30 and the two cutting tools 29 mounted thereon to gradually approach the corners of the door and window profile, completing the cornering operation. In this embodiment, the opening of the U-shaped plate 5 faces the workbench 1, and the U-shaped plate 5 is slidably mounted on the workbench 1.

[0032] A mounting plate 19 is fixedly mounted within the cavity 17. A motor 20 is fixedly mounted at the bottom of the mounting plate 19. The output shaft of the motor 20 passes through the mounting plate 19 and is fixedly mounted with a screw 21. A connecting plate 22 is threadedly sleeved on the screw 21. Slanted plates 34 are fixedly mounted at both ends of the connecting plate 22. Sliding plates 25 are slidably sleeved on each of the two inclined plates 34. A rotating mechanism is mounted at the bottom of each of the two guide blocks 3. The rotating mechanism cooperates with the corresponding sliding plate 25 and the tool head holder 30. The inclined plates 34 are perpendicular to the inclined slot 6.

[0033] like Figure 3 、 Figure 4 and Figure 5As shown, the rotating mechanism includes a vertical plate 28 fixedly mounted on the bottom of the guide block 3, a horizontal shaft 27 is rotatably mounted on the vertical plate 28, a gear 24 is fixedly mounted on one end of the horizontal shaft 27, a slide groove is provided at the bottom of the guide block 3, a rack 23 is slidably mounted in the slide groove, the bottom of the rack 23 is fixedly connected to the sliding plate 25, the rack 23 is meshed with the gear 24, a sliding column 26 is fixedly mounted on the bottom of the guide block 3, the sliding plate 25 is slidably sleeved on the sliding column 26, a vertical bevel gear 33 is fixedly mounted on the other end of the horizontal shaft 27, and a vertical shaft 31 is fixedly mounted on the bottom of the cutter head seat 30, the lower end of the vertical shaft 31 can rotatably pass through the guide block 3 and is connected to a horizontal bevel gear 32, and the horizontal bevel gear 32 is meshed with the vertical bevel gear 33. When it is necessary to replace the tools 29 of different specifications, the motor 20 is started, and the output shaft of the motor 20 rotates to drive the screw 21 to rotate. The rotational movement of the screw 21 is converted into the downward movement of the connecting plate 22 through the threaded transmission, and the connecting plate 22 drives the two inclined plates 34 to move downward synchronously. When the two inclined plates 34 move downward, they will push the two sliding plates 25 to move accordingly. During the downward movement of the sliding plate 25, the two racks 23 connected thereto will be driven to move downward synchronously. The rack 23 is meshed with the gear 24, thereby driving the two gears 24 to rotate. The rotation of the gear 24 drives the two horizontal shafts 27 and the two vertical bevel gears 33 installed at the ends of the horizontal shaft 27 to rotate synchronously. The vertical bevel gear 33 is meshed with the horizontal bevel gear 32, thereby driving the two horizontal bevel gears 32 and the two vertical shafts 31 connected thereto to rotate, finally realizing the synchronous rotation of the two tool head seats 30, completing the switching of the two tools 29.

[0034] like Figure 1 and Figure 2 As shown, two guide rods 2 are fixedly mounted on the inner walls of both sides of the guide hole 18, and the guide block 3 is slidably sleeved on the two guide rods 2, and the guide rods 2 are arranged parallel to the inclined plate 34. The advantage of this arrangement is that it is easy to limit the guide block 3.

[0035] like Figure 2 As shown, a mounting bracket 15 is fixedly mounted on the top of the workbench 1, a pressing cylinder 14 is fixedly mounted on the mounting bracket 15, and a pressing pad 13 is fixedly mounted on the movable end of the pressing cylinder 14. By starting the pressing cylinder 14, the pressing pad 13 can be moved downward, thereby positioning the triangular clamping plate 10 and the V-shaped baffle 16 to complete the top of the door and window and press it, which is convenient for later corner assembly.

[0036] like Figure 1 As shown, two placement plates 11 are fixedly installed on the side of the workbench 1, and the two placement plates 11 are symmetrically arranged based on the triangular clamping plate 10. The arrangement of the placement plates 11 facilitates the placement of doors and windows.

[0037] like Figure 1 and Figure 2As shown, a control box 8 is fixedly mounted on the side of the workbench 1. A foot switch 12 is provided on one side of the workbench 1. The foot switch 12 is electrically connected to the control box 8. The foot switch 12 controls the solenoid valves connected to the front cylinder 9 and the rear cylinder 4, mainly through the on-off circuit and the linkage of the air circuit. There are two foot switches 12, one for controlling the front cylinder 9 and the other for controlling the rear cylinder 4.

[0038] Working Principle: When in use, first place the door and window profile to be angled on the corresponding position of the V-shaped baffle 16. Then, activate the front cylinder 9. The movable end of the front cylinder 9 pushes the triangular clamping plate 10 toward the profile. The triangular clamping plate 10 cooperates with the V-shaped baffle 16 to firmly fix the door and window profile between them, achieving precise positioning. At this point, the door and window profile is actually pressed against the top of the workbench 1.

[0039] After the fixation is completed, the rear cylinder 4 is started, and the movable end of the rear cylinder 4 is stretched outward, driving the U-shaped plate 5 connected to it to move synchronously. When the U-shaped plate 5 moves, the inclined grooves 6 on both sides thereof will guide the two L-shaped slides 7, prompting the two L-shaped slides 7 to move toward each other along the preset trajectory, thereby driving the two guide blocks 3 to approach each other, and finally making the two tool head seats 30 and the two tools 29 installed thereon gradually approach the corners of the door and window profiles, completing the corner assembly operation. When the guide block 3 moves, it will drive the sliding plate 25 to slide on the inclined plate 34 so that it will not get stuck.

[0040] When it is necessary to replace the tools 29 of different specifications, the motor 20 is started, and the output shaft of the motor 20 rotates to drive the screw 21 to rotate. The rotational movement of the screw 21 is converted into the downward movement of the connecting plate 22 through the threaded transmission, and the connecting plate 22 drives the two inclined plates 34 to move downward synchronously. When the two inclined plates 34 move downward, they will push the two sliding plates 25 to move accordingly. During the downward movement of the sliding plate 25, the two racks 23 connected thereto will be driven to move downward synchronously. The rack 23 is meshed with the gear 24, thereby driving the two gears 24 to rotate. The rotation of the gear 24 drives the two horizontal shafts 27 and the two vertical bevel gears 33 installed at the ends of the horizontal shaft 27 to rotate synchronously. The vertical bevel gear 33 is meshed with the horizontal bevel gear 32, thereby driving the two horizontal bevel gears 32 and the two vertical shafts 31 connected thereto to rotate, finally realizing the synchronous rotation of the two tool head seats 30, completing the switching of the two tools 29.

[0041] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
