Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing technology for doors and windows, specifically a composite drilling and milling fastening device for aluminum profiles for doors and windows. Background Technology

[0002] As we all know, with the rapid development of the construction industry, aluminum alloy doors and windows are widely used due to their advantages such as light weight, corrosion resistance and aesthetics. In the production process of aluminum alloy doors and windows, it is necessary to perform composite processing such as drilling, milling grooves and milling tenons on the ends of the profiles. As a core component, the performance of the fastening device directly affects the processing accuracy and production efficiency.

[0003] Currently, the fastening devices of existing aluminum profile composite drilling and milling equipment for doors and windows generally adopt a separate design for the clamping mechanism and the supporting mechanism, with each equipped with an independent drive system and control unit. For example, Chinese utility model patent with publication number CN221134855U discloses a drilling and milling device for thermally broken aluminum doors and windows, in which the clamping unit and the material supporting unit are respectively set on the support base. The clamping unit is driven by an independent cylinder to clamp the profile, while the material supporting unit is supported by a separate lifting mechanism. Another example is Chinese utility model patent with publication number CN209578242U, which discloses a profile drilling and milling equipment, in which the lower pressure roller mechanism and the side pressure mechanism are driven by independent cylinders, and the material supporting roller of the feeding channel is also a separately set passive structure.

[0004] The aforementioned existing technology has several drawbacks. First, the clamping and lifting mechanisms use independent drive systems, making it difficult to precisely synchronize their actions. If the lifting mechanism moves before the clamping mechanism, it will lift the profile upwards, causing the profile end face to detach from the positioning reference surface, resulting in an axial positioning error of over 0.5mm. If the clamping mechanism moves before the lifting mechanism, the lifting mechanism will forcibly push the already clamped profile when it rises, causing internal stress in the profile. After processing, the profile will spring back and deform, severely affecting processing accuracy. Second, the independent drive system requires multiple sets of cylinders, solenoid valves, air pipes, and electrical wiring, which not only increases the equipment manufacturing cost and assembly difficulty but also increases the failure rate and subsequent maintenance costs. Third, the existing lifting mechanism is mostly in a free state when the equipment is in standby mode, making it prone to displacement due to vibration and collision. The lifting height needs to be recalibrated before each use, increasing auxiliary time and reducing production efficiency. Summary of the Invention

[0024] See Figures 1-12 A composite drilling and milling fastening device for aluminum profiles of doors and windows includes a machine body 1, which is a composite drilling and milling machine tool for aluminum profiles of doors and windows. A worktable 5 is fixedly connected inside the machine body 1. A fixing component 4 is slidably connected to one side of the worktable 5. A lifting component 3 is provided inside the worktable 5. Linkage components 2 are provided on both sides of the worktable 5, and one side of the linkage component 2 is fixedly connected to one side of the fixing component 4.

[0025] First, refer to Figure 2 , Figure 3 , Figure 4 , Figure 11 and Figure 12 In this embodiment, the fixing component 4 includes an operating table 401, two sets of support seats 403 and two sets of clamping members. The operating table 401 is slidably connected to one side of the workbench 5, the support seats 403 are fixedly connected to one side of the workbench 5, and a cylinder 402 is fixedly installed on one side of the support seats 403.

[0026] The clamping component includes a sliding plate 404, which is fixedly installed at the output end of the cylinder 402 and slidably connected inside the operating table 401. An anti-detachment block 405 is slidably connected inside the sliding plate 404. A clamping plate 407 is fixedly connected to one side of the anti-detachment block 405, and the width of the side of the anti-detachment block 405 near the clamping plate 407 is smaller than the width of the side away from the clamping plate 407, thereby preventing the anti-detachment block 405 from detaching from the sliding plate 404. Two sets of baffle plates 406 are fixedly connected to one side of the clamping plate 407. One side of the sliding plate 404 is fixedly connected to the linkage assembly 2.

[0027] After the cylinder 402 is activated, the output end of the cylinder 402 will push the sliding plate 404 to move, and the displacement of the sliding plate 404 will push the clamping plate 407 to move, thereby clamping the door and window aluminum profile workpiece on the operating table 401.

[0028] Then, refer to Figures 3 to 8 In this embodiment, the linkage component 2 includes a movable plate 201, a movable plate 213, and a locking component. The movable plate 201 is slidably connected to one side of the workbench 5. A connecting frame 206 is fixedly connected to one side of the movable plate 201. The side of the connecting frame 206 away from the movable plate 201 is fixedly connected to the sliding plate 404. A push plate 203 is fixedly connected to one side of the movable plate 201. Two sets of top blocks 202 are slidably connected inside the movable plate 201. The vertical cross-section of the top block 202 is triangular. A connecting plate 212 is fixedly connected to one side of the top block 202. One side of each of the two sets of connecting plates 212 is fixedly connected to a slider 207. A limiting plate 211 is fixedly connected to one side of the movable plate 201. The slider 207 is slidably connected to the outside of the limiting plate 211. A fixed plate 210 is fixedly connected to the outside of the limiting plate 211. A movable plate 208 is slidably connected to the outside of the limiting plate 211. A first spring 209 is fixedly connected between the movable plate 208 and the fixed plate 210.

[0029] The movable plate 213 is slidably connected to one side of the worktable 5. A guide plate 204 and a mounting plate 214 are fixedly connected to one side of the movable plate 213. A rack 217 is fixedly connected to one side of the mounting plate 214. The movable plate 213 and the push plate 203 are parallel. Two sets of second springs 215 are fixedly connected to one side of the movable plate 213. The end of the second spring 215 away from the movable plate 213 is fixedly connected to the inside of the worktable 5.

[0030] The locking assembly includes a parallel plate 218, which is slidably connected to one side of the worktable 5. A locking plate 216 is fixedly connected to one side of the parallel plate 218, and the locking plate 216 is located between the moving plate 213 and the worktable 5. A central shaft 224 is fixedly connected to both sides of the locking plate 216. A pulley 223 is rotatably connected to the outer side of the central shaft 224. Two sets of blocking plates 222 are fixedly connected to the outer side of the central shaft 224, and the two sets of blocking plates 222 are located on both sides of the pulley 223.

[0031] Specifically, in order to maintain the balance of the parallel plate 218, fixed plates 205 are fixedly connected to both sides of the workbench 5. Two sets of balance bars 221 are fixedly connected to one side of the fixed plate 205, and the parallel plate 218 is slidably connected to the outside of the two sets of balance bars 221. Thus, on the one hand, the balance bars 221 maintain the balance of the parallel plate 218 during movement, preventing the parallel plate 218 from becoming unbalanced and swaying during movement, and ensuring the normal displacement of the parallel plate 218. On the other hand, the balance bars 221 restrict the direction of the parallel plate 218, preventing the device from failing due to misalignment of the parallel plate 218, and ensuring the normal use of the device.

[0032] Meanwhile, in order to enable the parallel plate 218 to move back quickly, two sets of third springs 219 are fixedly connected between the parallel plate 218 and the fixed plate 205. Thus, when the parallel plate 218 is pushed, the third springs 219 will be squeezed by the parallel plate 218, and when the parallel plate 218 is no longer pushed, the third springs 219 will bounce the parallel plate 218 back quickly.

[0033] Furthermore, in order to prevent the parallel plate 218 from excessively shifting back and detaching from the balance bar 221, a disc 220 is fixedly connected to the outside of the balance bar 221. The disc 220 is made of rubber and is located on the side of the parallel plate 218 away from the third spring 219. Thus, the disc 220 can block the parallel plate 218 and prevent the parallel plate 218 from excessively shifting back and detaching from the balance bar 221.

[0034] This composite drilling and milling fastening device for aluminum profiles of doors and windows has a locking component. When the cylinder 402 is not activated, the locking component will lock and fix the moving plate 213, preventing the lifting component 3 from lifting the clamping parts when not in operation. This effectively prevents the internal parts from sliding or shifting on their own during the device's idle period, eliminates the phenomenon of the clamping parts being lifted without reason and abnormal contact between parts, and reduces the deformation and wear caused by long-term compression of parts.

[0035] When the sliding plate 404 displaces and pushes the connecting frame 206 to move, the connecting frame 206 will push the movable plate 201 to move. The displacement of the movable plate 201 will push the top block 202 to move. At this time, the displacement of the top block 202 will push the pulley 223 to move upward along the inclined surface of the top block 202. The displacement of the pulley 223 will push the locking plate 216 to move longitudinally by pushing the central shaft 224. The displacement of the locking plate 216 will disengage from the movable plate 213. At this time, the movable plate 213 is no longer restricted by the locking plate 216. Then the movable plate 204... The continued movement of 01 will cause the push plate 203 to push the moving plate 213 towards the worktable 5. At the same time, after contacting the worktable 5, the top block 202 will move towards the movable plate 201. At this time, the top block 202 will push the slider 207 to move by pushing the connecting plate 212. The displacement of the slider 207 will squeeze the first spring 209 by pushing the movable plate 208. The displacement of the moving plate 213 will push the mounting plate 214 to move horizontally. The displacement of the mounting plate 214 will push the rack 217 to move horizontally.

[0036] Finally, see Figure 4 , Figure 9 and Figure 10 In this embodiment, the lifting assembly 3 includes two sets of mounting plates 307. A fixing frame 306 is fixedly connected to both sides of each mounting plate 307. One side of the fixing frame 306 is fixedly connected to the inside of the workbench 5. A rotating column 311 is rotatably arranged between the two sets of mounting plates 307. A support plate 312 is arranged on the outer side of the rotating column 311, located between the two sets of mounting plates 307. The support plate 312 is blocked by the two sets of mounting plates 307 and cannot detach from them. A gear 313 is arranged on the outer side of the support plate 312. Two sets of racks 217 mesh with the gear 313, and the two sets of racks 217 are respectively located on the outer side of the gear 313. On both sides, a threaded tube 302 is provided at one end of the rotating column 311. A sleeve 304 is screwed onto the outside of the threaded tube 302. Mounting seats 305 are provided on both sides of the sleeve 304. A placement rack 303 is provided on one side of the mounting seat 305. One side of each of the two placement racks 303 is fixedly mounted to a top roller 301 that is slidably disposed inside the worktable 5. One end of the top roller 301 is fixedly mounted to one side of the operating table 401. A movable ring 308 is provided on the outside of the top roller 301. A fixed ring 309 is provided inside the worktable 5. Two sets of guide rods 310 are provided on one side of the movable ring 308. The guide rods 310 are slidably disposed inside the fixed ring 309.

[0037] When gear 313 is pushed, gear 313 will drive the rotating column 311 to rotate by driving the support plate 312 to rotate. The rotation of the rotating column 311 will drive the threaded tube 302 to rotate. The rotation of the threaded tube 302 will drive the sleeve 304 to move linearly. The displacement of the sleeve 304 will push the mounting base 305 to move longitudinally. The displacement of the mounting base 305 will push the placement frame 303 to move longitudinally. The displacement of the placement frame 303 will push the top roller 301 to move longitudinally. The displacement of the top roller 301 will push the workpiece to move longitudinally by pushing the operating table 401.

[0038] This composite drilling and milling fastening device for aluminum profiles of doors and windows works by cooperating with the linkage component 2 with the fixing component 4 and the lifting component 3 respectively. When the cylinder 402 drives the clamping component to move horizontally, the linkage component 2 will be driven by the clamping component. At this time, the linkage component 2 will drive the lifting component 3 to lift the clamping component. Thus, the workpiece can be lifted while being clamped. This eliminates the traditional design of separate and independent driving of clamping and lifting structures, simplifies the overall assembly structure of the equipment, reduces the investment in unnecessary pneumatic and electrical control components, and reduces production costs and the difficulty of later inspection and maintenance.

[0039] This composite drilling and milling fastening device for aluminum profiles of doors and windows, in use, first places the aluminum profile workpiece on the operating table 401, positioning it between two sets of clamping plates 407. Then, the cylinder 402 is activated, causing its output end to push the sliding plate 404 to move. The displacement of the sliding plate 404 will push the clamping plate 407 to move, thereby clamping the aluminum profile workpiece on the operating table 401. Furthermore, the displacement of the sliding plate 404 will push the connecting frame 206 to move. When the sliding plate 404 pushes the connecting frame 206 to move, the connecting frame 206 will push the movable plate 201 to move. The displacement of the movable plate 201 will push the top block 202 to move. At this time, the displacement of the top block 202 will push the pulley 223 to move upward along the inclined surface of the top block 202. The displacement of 3 will push the locking plate 216 longitudinally by pushing the central shaft 224. The displacement of the locking plate 216 will disengage from the moving plate 213. At this time, the moving plate 213 is no longer restricted by the locking plate 216. Then, the continued movement of the movable plate 201 will cause the push plate 203 to push the moving plate 213 towards the worktable 5. At the same time, the top block 202 will move towards the movable plate 201 after contacting the worktable 5. At this time, the top block 202 will push the slider 207 to move by pushing the connecting plate 212. The displacement of the slider 207 will squeeze the first spring 209 by pushing the movable disk 208. The displacement of the moving plate 213 will push the mounting plate 214 to move horizontally. The displacement of the mounting plate 214 will push the rack 217 to move horizontally.

[0040] The displacement of rack 217 will drive gear 313 to rotate. When gear 313 is driven, gear 313 will drive rotating column 311 to rotate by driving support plate 312 to rotate. The rotation of rotating column 311 will drive threaded tube 302 to rotate. The rotation of threaded tube 302 will drive sleeve 304 to move linearly. The displacement of sleeve 304 will drive mounting base 305 to move longitudinally. The displacement of mounting base 305 will drive placement frame 303 to move longitudinally. The displacement of placement frame 303 will drive top roller 301 to move longitudinally. The displacement of top roller 301 will drive workpiece to move longitudinally by pushing operating table 401, thereby completing the workpiece lifting operation.
