Description
Technical Field
[0001] This utility model relates to the field of window frame production technology, and in particular to a window frame production device. Background Technology
[0002] Window frames are an important component of windows, playing a crucial role in their function, appearance, and energy efficiency. The production of window frames is a systematic process involving multiple steps and technologies to ensure the quality and performance of the final product. According to the design drawings, the selected materials are cut into appropriate sizes and shapes. After processing such as grinding, drilling, and milling, the various components are assembled together and surface treatments such as painting and film application are performed. After passing inspection, production is completed.
[0003] The production of window frames involves assembling various components through interlocking, and then maintaining the splicing effect with pins and movable corner brackets. This requires a large number of additional parts. Another method is to strike the corners after assembly to make the window frame splice more secure. However, existing machines can only strike one corner at a time, and a window frame needs to be rotated multiple times to strike the corners in order to complete the process. Therefore, this application provides a window frame production device to meet the needs. Utility Model Content
[0004] The technical problem this utility model aims to solve is to provide a window frame production device to address the issue that existing window frame production methods involve assembling various components through interlocking, and then maintaining the splicing effect with pins and movable corner brackets. This requires a large number of additional parts. Another method is to strike the corners after assembly to make the window frame spliced more firmly, but existing machines can only strike one corner at a time, and a window frame needs to be rotated multiple times to strike the corners in order to complete the process.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A window frame manufacturing apparatus includes a workbench. The top of the workbench has four opposing sliding grooves (first and second). A fixing mechanism (first) is installed inside the sliding grooves, and a fixing mechanism (second) is installed inside the sliding grooves. The fixing mechanisms (first and second) are used to fix the window frame body. Each fixing mechanism (first and second) is equipped with an adjustment mechanism. A limiting pin (third) is fixedly connected to the center of the bottom of the workbench. A turntable is fitted onto the limiting pin (third), and the turntable has four arc-shaped sliding grooves (four fourth). The device includes a clamping block 1, a slider 1 fixedly connected to the bottom of the clamping block 1, the slider 1 slidably connected to the slide groove 1, and a connecting column fixedly connected to the bottom of the slider 1. The connecting columns on the same side of the worktable are fixedly connected together by connecting blocks 1. Connecting blocks 2 are fixedly connected to each other on the side of the connecting blocks 1 that is close to each other. Connecting blocks 3 are rotatably connected to the end of the connecting blocks 2 that is away from the connecting blocks 1. The same connecting block 4 is rotatably connected to each of the connecting blocks 3. A cylinder is fixedly connected to the bottom of the limiting pin 3 and to the connecting block 4.
[0007] Preferably, the fixing mechanism two includes a clamping block two that is slidably connected to the slide groove two. The bottom of the clamping block two extends out of the slide groove two. A connecting rod is provided between the clamping blocks two on the same side of the worktable. The outer surfaces of the two ends of the connecting rod are provided with threads in opposite directions. The connecting rod is helically connected to the clamping block two through the threads and passes through the clamping block two. A gear is fixedly connected to one end of the connecting rod.
[0008] Preferably, the adjusting mechanism includes grooves formed on the top of both clamping block one and clamping block two, with a limiting block slidably connected inside the grooves. One side of clamping block one and clamping block two are provided with through grooves communicating with the grooves. An internally threaded block that can slide inside the through groove is fixedly connected to the side of clamping block one and clamping block two near the through groove. A limiting pin one is slidably connected inside the through groove. The limiting pin one is helically connected to the internally threaded block to fix the position of the limiting block.
[0009] Preferably, the top center of the workbench has four opposing sliding grooves 3. The sliding grooves 3 are inclined and have sliders 2 slidably connected inside. The top of the sliders 2 is fixedly connected to an inner top block, and the bottom of the sliders 2 is fixedly connected to a limit pin 2. The limit pin 2 passes through the sliding grooves 4 on the turntable and is slidably connected to the sliding grooves 4.
[0010] Preferably, a cylinder is fixedly connected to one side of the bottom of the turntable, and a limiting frame is fixedly connected to the bottom of the worktable near the cylinder. One end of the connecting rod, which is fixedly connected to the gear, extends through one side of the limiting frame and into the interior. A side groove is provided on the side of the limiting frame near the cylinder.
[0011] Preferably, a rack is provided inside the limiting frame one, the rack meshes with the gear, a slider three is fixedly connected to one side of the rack, the slider three extends out of the limiting frame one and is slidably connected to the side groove, and a limiting frame two is fixedly connected to the end of the slider three away from the limiting frame one, the limiting frame two is located below the cylinder and frames the cylinder.
[0012] Compared with the prior art, this utility model has at least the following beneficial effects:
[0013] In the above scheme, by setting a fixing mechanism one, after the window frame body is assembled by splicing, the window frame body is placed in the middle of the top of the workbench. The cylinder is activated, which pushes the connecting block four downward, causing the connecting blocks three at both ends of the connecting block four to rotate. This causes the connecting blocks two to move towards each other, which in turn causes the connecting block one to move. The connecting block one then drives the slider one to slide towards the middle of the workbench through the connecting column, thereby causing the clamping block one to abut against the window frame body. The advantage of this is that it can quickly and easily clamp both sides of the window frame body, fixing the position of the window frame body and facilitating subsequent operations.
[0014] By setting up a second fixing mechanism, after the window frame body is fixed in position, pulling the rack will cause the gear to rotate, which in turn drives the connecting rod to rotate. The rotating connecting rod, in turn, drives the threads at both ends to rotate. These threads, moving in opposite directions, will cause the clamping blocks two to move closer together inside the sliding groove two, clamping the other two sides of the window frame body that are not clamped. By setting up an inner top block, when the rack is pulled, it will cause the slider three to slide within the side groove of the limiting frame one. As the slider three slides, it will cause the limiting frame two to move accordingly. The movement of the limiting frame two will then cause the cylinder to move. When the column moves, it drives the turntable to rotate on the limiting pin three. When the turntable rotates, the limiting pin two slides inside the arc-shaped slide groove four, so that the limiting pin two drives the inner top block to move and press against the inner wall of the window frame body through the slider two. The advantage of this is that while pulling the rack allows the clamping block two to clamp the other two sides of the window frame body that are not clamped, it also allows the inner top block to press against the inner wall of the window frame body, and the window frame body is further fixed. The cooperation between the clamping block two and the clamping block one will cause the four corners of the window frame body to be impacted at the same time, thereby making the window frame splicing more solid, while saving the use of additional parts such as pins and movable corner brackets.
[0015] By setting an adjustment mechanism, when clamps one and two move closer to and abut against the side of the window frame body, the limiting block will abut against the irregular part of the window frame body, making the window frame body more stable and strengthening the impact effect on the corners of the window frame body. When fixing window frame bodies of different heights, the limiting pin one can be rotated so that it does not abut against clamps one and two. At this time, the limiting block is loose, and the height position of the limiting block can be adjusted as needed. After completion, the limiting pin one is rotated again to abut against clamps one and two to fix the limiting block. The advantage of this is that the position of the limiting block can be adjusted as needed, thereby adapting to more models of window frame bodies. Attached Figure Description

[0024] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model. However, this is only for illustrative purposes and is not intended to limit this utility model to the specific structure, device and environment. According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation
[0025] The window frame production apparatus of this utility model is described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0026] like Figures 1-4 As shown, an embodiment of this utility model provides a window frame production device, including a workbench 1. The top of the workbench 1 has four opposing sliding grooves 5 and 6. A fixing mechanism 2 is installed inside the sliding groove 5, and a fixing mechanism 3 is installed inside the sliding groove 6. The fixing mechanisms 2 and 3 are used to fix the window frame body 8. Both the fixing mechanisms 2 and 3 are equipped with adjusting mechanisms 4. A limiting pin 3 15 is fixedly connected to the middle of the bottom of the workbench 1. A turntable 12 is fitted onto the limiting pin 3 15, and the turntable 12 has four arc-shaped sliding grooves 4 13 for fixing... Mechanism 12 includes clamping block 121. A slider 122 is fixedly connected to the bottom of clamping block 121. Slider 122 is slidably connected to slide groove 15. A connecting post 23 is fixedly connected to the bottom of slider 122. The connecting posts 23 on the same side of the worktable 1 are fixedly connected together by connecting block 124. Connecting block 25 is fixedly connected to the side of connecting block 124 that is close to each other. Connecting block 36 is rotatably connected to the end of connecting block 25 that is away from connecting block 124. The same connecting block 47 is rotatably connected between connecting blocks 326. A cylinder is fixedly connected to connecting block 427 at the bottom of limiting pin 315.
[0027] By setting a fixing mechanism 2, after the window frame body 8 is assembled by interlocking, the window frame body 8 is placed in the middle of the top of the workbench 1. The cylinder is activated, which pushes the connecting block 4 27 downward, causing the connecting blocks 3 26 at both ends of the connecting block 4 27 to rotate. This causes the connecting blocks 25 to move towards each other, which in turn causes the connecting block 1 24 to move. The connecting block 1 24 then drives the slider 1 22 to slide towards the middle of the workbench 1 through the connecting post 23. This causes the clamping block 1 21 to come into contact with the window frame body 8. The advantage of this is that it can quickly and easily clamp the two sides of the window frame body 8, fixing the position of the window frame body 8 and facilitating subsequent operations.
[0028] like Figures 1-5 As shown, the fixing mechanism 2 3 includes a clamping block 2 31 slidably connected to the slide groove 2 6. The bottom of the clamping block 2 31 extends out of the slide groove 2 6. A connecting rod 32 is provided between the clamping blocks 2 31 on the same side of the worktable 1. The outer surfaces of the two ends of the connecting rod 32 are provided with threads 33 in opposite directions. The connecting rod 32 is spirally connected to the clamping block 2 31 through the threads 33 and passes through the clamping block 2 31. A gear 34 is fixedly connected to one end of the connecting rod 32. Four opposing slide grooves 3 7 are opened in the middle of the top of the worktable 1. The slide grooves 3 7 are inclined and slide sliders 2 10 are slidably connected inside. An inner top block 9 is fixedly connected to the top of the slide sliders 2 10. A limit pin 2 11 is fixedly connected to the bottom of the slide sliders 2 10. The limit pin 2 11 passes through the slide groove 4 1 on the turntable 12. 3. It is slidably connected to the slide groove 13. A cylinder 14 is fixedly connected to one side of the bottom of the turntable 12. A limit frame 16 is fixedly connected to the bottom of the worktable 1 near the cylinder 14. One end of the connecting rod 32 is fixedly connected to the gear 34 and extends through one side of the limit frame 16 into the interior. A side groove 20 is opened on the side of the limit frame 16 near the cylinder 14. A rack 17 is provided inside the limit frame 16. The rack 17 meshes with the gear 34. A slider 3 18 is fixedly connected to one side of the rack 17. The slider 3 18 extends out of the limit frame 16 and is slidably connected to the side groove 20. A limit frame 2 19 is fixedly connected to the end of the slider 3 18 away from the limit frame 16. The limit frame 2 19 is located below the cylinder 14 and frames the cylinder 14.
[0029] By setting the fixing mechanism 2 3, after the position of the window frame body 8 is fixed, the rack 17 is pulled. When the rack 17 moves, it drives the gear 34 to rotate, which in turn drives the connecting rod 32 to rotate. When the connecting rod 32 rotates, it drives the threads 33 at both ends to rotate. The threads 33 in opposite directions drive the clamping blocks 2 31 to move closer to each other inside the slide groove 2 6, clamping the other two sides of the window frame body 8 that are not clamped. By setting the inner top block 9, when the rack 17 is pulled, the rack 17 drives the slider 3 18 to slide in the side groove 20 on the limiting frame 1 16. When the slider 3 18 slides, it drives the limiting frame 2 19 to move accordingly. When the limiting frame 2 19 moves, it drives the cylinder 1 4. Movement: When the cylinder 14 moves, it drives the turntable 12 to rotate on the limiting pin three 15. When the turntable 12 rotates, the limiting pin two 11 slides inside the arc-shaped sliding groove four 13, so that the limiting pin two 11 drives the inner top block 9 to move and press against the inner wall of the window frame body 8 through the slider two 10. The advantage of doing this is that while pulling the rack 17 to make the clamping block two 31 clamp the other two sides of the window frame body 8 that are not clamped, it also makes the inner top block 9 press against the inner wall of the window frame body 8, and the window frame body 8 is further fixed. The cooperation between the clamping block two 31 and the clamping block one 21 will make the four corners of the window frame body 8 impact at the same time, so that the window frame splicing is more solid, and at the same time saves the use of additional parts such as pins and movable corner brackets.
[0030] like Figure 1 , Figure 4 and Figure 5 As shown, the adjustment mechanism 4 includes grooves 41 on the top of clamping block 21 and clamping block 31. A limiting block 42 is slidably connected inside the grooves 41. A through groove 43 communicating with the grooves 41 is provided on one side of clamping block 21 and clamping block 31. An internally threaded block 45 that can slide inside the through groove 43 is fixedly connected to the side of clamping block 21 and clamping block 31 near the through groove 43. A limiting pin 44 is slidably connected inside the through groove 43. The limiting pin 44 and the internally threaded block 45 are spirally connected to fix the position of the limiting block 42.
[0031] By setting the adjustment mechanism 4, when clamping blocks 21 and 31 move closer to and abut against the side of the window frame body 8, the limiting block 42 will abut against the irregular part of the window frame body 8, making the window frame body 8 more stable and strengthening the impact effect on the corners of the window frame body 8. When fixing window frame bodies 8 of different heights, the limiting pin 44 can be rotated so that the limiting pin 44 does not abut against clamping blocks 21 and 31. At this time, the limiting block 42 is loose, and the height position of the limiting block 42 can be adjusted as needed. After completion, the limiting pin 44 is rotated again so that it abuts against clamping blocks 21 and 31 to fix the limiting block 42. The advantage of doing this is that the position of the limiting block 42 can be adjusted as needed, thereby adapting to more models of window frame bodies 8.
[0032] The technical solution provided by this utility model, by setting a fixing mechanism 2, after the window frame body 8 is assembled by splicing, the window frame body 8 is placed in the middle of the top of the workbench 1. The cylinder is activated, which pushes the connecting block 4 27 downward, causing the connecting blocks 3 26 at both ends of the connecting block 4 27 to rotate, so that the connecting blocks 25 move towards each other, causing the connecting block 1 24 to move. The connecting block 1 24 drives the slider 1 22 to slide in the sliding groove 5 towards the middle of the workbench 1 through the connecting column 23, so that the clamping block 1 21 abuts against the window frame body 8. The advantage of this is that it can quickly and easily clamp the two sides of the window frame body 8, fix the position of the window frame body 8, and facilitate subsequent operations.
[0033] By setting the fixing mechanism 2 3, after the position of the window frame body 8 is fixed, the rack 17 is pulled. When the rack 17 moves, it drives the gear 34 to rotate, which in turn drives the connecting rod 32 to rotate. When the connecting rod 32 rotates, it drives the threads 33 at both ends to rotate. The threads 33 in opposite directions drive the clamping blocks 2 31 to move closer to each other inside the slide groove 2 6, clamping the other two sides of the window frame body 8 that are not clamped. By setting the inner top block 9, when the rack 17 is pulled, the rack 17 drives the slider 3 18 to slide in the side groove 20 on the limiting frame 1 16. When the slider 3 18 slides, it drives the limiting frame 2 19 to move accordingly. When the limiting frame 2 19 moves, it drives the cylinder 1 4. Movement: When the cylinder 14 moves, it drives the turntable 12 to rotate on the limiting pin three 15. When the turntable 12 rotates, the limiting pin two 11 slides inside the arc-shaped sliding groove four 13, so that the limiting pin two 11 drives the inner top block 9 to move and press against the inner wall of the window frame body 8 through the slider two 10. The advantage of doing this is that while pulling the rack 17 to make the clamping block two 31 clamp the other two sides of the window frame body 8 that are not clamped, it also makes the inner top block 9 press against the inner wall of the window frame body 8, and the window frame body 8 is further fixed. The cooperation between the clamping block two 31 and the clamping block one 21 will make the four corners of the window frame body 8 impact at the same time, so that the window frame splicing is more solid, and at the same time saves the use of additional parts such as pins and movable corner brackets.
[0034] By setting the adjustment mechanism 4, when clamping blocks 21 and 31 move closer to and abut against the side of the window frame body 8, the limiting block 42 will abut against the irregular part of the window frame body 8, making the window frame body 8 more stable and strengthening the impact effect on the corners of the window frame body 8. When fixing window frame bodies 8 of different heights, the limiting pin 44 can be rotated so that the limiting pin 44 does not abut against clamping blocks 21 and 31. At this time, the limiting block 42 is loose, and the height position of the limiting block 42 can be adjusted as needed. After completion, the limiting pin 44 is rotated again so that it abuts against clamping blocks 21 and 31 to fix the limiting block 42. The advantage of doing this is that the position of the limiting block 42 can be adjusted as needed, thereby adapting to more models of window frame bodies 8.
