Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window processing technology, and in particular to a CNC end milling machine for aluminum alloy door and window processing. Background Technology

[0002] Aluminum alloy doors and windows are products made primarily of extruded aluminum alloy profiles for frames, mullions, and sashes. They are lightweight, high-strength, corrosion-resistant, have excellent sealing properties, are aesthetically pleasing, and are highly machinable. They are widely used in various types of buildings. Using CNC end milling machines to process aluminum alloy doors and windows enables high-precision machining, ensuring the dimensions and surface quality of the doors and windows, guaranteeing their sealing and stability after installation. Automated operation can significantly improve production efficiency and can also process complex shapes to meet diverse design needs. At the same time, a unified processing procedure can ensure consistent quality, reduce human error, and a well-planned processing path can improve material utilization and reduce production costs.

[0003] However, existing CNC end milling machines have many shortcomings in actual processing. First, each time the milling machine is used, the workpiece is placed on the worktable by manual operation and extends a certain distance from the worktable so that it contacts the baffle on the cutting machine. The baffle added to the cutting part affects the rotation angle of the cutting blade and affects the overall cutting efficiency. Second, the position of the workpiece contacting the baffle is different each time. Most milling machines need to identify the length and position of the workpiece before starting the cutting process, which is inefficient and easily affected by human error, making it impossible to meet the needs of modern large-scale, high-precision aluminum alloy door and window production.

[0004] Therefore, it is necessary to provide a new CNC end milling machine for processing aluminum alloy doors and windows to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a CNC end milling machine for processing aluminum alloy doors and windows.

[0006] The CNC end milling machine for processing aluminum alloy doors and windows provided by this utility model includes: a base, a worktable mounted on the top of the base, a workpiece to be processed placed on the top of the worktable, a positioning plate for positioning the workpiece mounted on one side of the worktable, an L-shaped rod for pushing the workpiece mounted on the side of the worktable away from the positioning plate, a first driving component for driving the worktable to move installed inside both the base and the worktable, a clamping component for clamping the workpiece mounted inside the worktable, and a second driving component for driving the L-shaped rod to move installed inside the worktable.

[0007] Preferably, the first drive assembly includes: a drive motor, a first gear and a fixed rack. The drive motor is fixedly connected inside the worktable, the first gear is fixedly connected to the output end of the drive motor, a guide rail is provided inside the base, and a fixed rack is fixedly connected to the base at the bottom of the guide rail. The first gear meshes with the fixed rack.

[0008] Preferably, the clamping assembly includes: a second gear, a bidirectional toothed plate, a fixed gear, a bidirectional threaded rod, and a clamping plate. The second gear is fixedly connected to the output end of the drive motor. The bidirectional toothed plate is slidably connected inside the worktable, and the bottom of the bidirectional toothed plate meshes with the second gear. The fixed gear is rotatably connected inside the worktable, and the fixed gear meshes with the top of the bidirectional toothed plate. A bidirectional threaded rod is fixedly connected to the shaft of the fixed gear, and clamping plates for clamping the object body are threaded to both ends of the bidirectional threaded rod.

[0009] Preferably, the second drive assembly includes: a fixed threaded rod and a threaded sleeve, the fixed threaded rod is fixedly connected to the end of the bidirectional toothed plate away from the positioning plate, the threaded sleeve is threadedly connected to the outer wall of the fixed threaded rod, and the end of the threaded sleeve away from the fixed threaded rod is rotatably connected to the L-shaped rod.

[0010] Preferably, both ends of the bidirectional toothed plate are symmetrically fixedly connected to fixing blocks, one end of the fixing block is fixedly connected to a slide rod, and both ends of the bidirectional toothed plate are symmetrically installed with slide plates. The slide plates slide within the corresponding two slide rods. The outer walls of multiple sets of slide rods are all equipped with springs, one end of the spring is fixedly connected to the fixing block, and the other end of the spring is fixedly connected to the slide plate.

[0011] Preferably, a friction roller is rotatably connected inside the worktable, the friction roller is fixedly connected to the positioning plate, and a friction block is fixedly connected to the end of the bidirectional toothed plate away from the fixed threaded rod, the friction block being in contact with the friction roller.

[0012] Preferably, the top of the positioning plate is located above the top of the worktable.

[0013] Preferably, the base has an auxiliary slide groove at the top, and an auxiliary roller is rotatably connected to the bottom of the worktable, with the auxiliary roller sliding within the auxiliary slide groove.

[0014] Compared with related technologies, the CNC end milling machine for processing aluminum alloy doors and windows provided by this utility model has the following beneficial effects:

[0015] Automated, precise positioning and efficient clamping:

[0016] By coordinating the design of the first drive component, the clamping component, and the second drive component, the traditional method of manually placing profiles is changed, realizing automatic positioning and precise clamping of the object body. Under the action of the second drive component, the L-shaped rod can automatically push the object body to extend a fixed distance outside the worktable, avoiding the deviation of the position when placed manually. At the same time, the clamping component uses gear transmission to realize the synchronous movement of the clamping plates in opposite directions, ensuring that the object body is firmly fixed without the need for additional position identification, effectively improving processing efficiency and accuracy, and meeting the needs of modern large-scale production.

[0017] Optimize the cutting workspace:

[0018] This device uses a positioning plate design instead of a baffle, providing the cutting blade with more room to move and effectively avoiding the problem of low cutting efficiency caused by the baffle restricting the cutting blade's rotation angle.

[0019] Linkage drives reduce energy consumption and costs:

[0020] The first drive assembly drives the worktable to move through a gear and rack transmission, while simultaneously providing power to the clamping assembly and the second drive assembly, realizing multi-component linkage drive. This integrated power transmission method reduces the need for independent drive devices, simplifies the equipment structure, reduces energy consumption and equipment manufacturing costs, and facilitates later maintenance.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 5 A CNC end milling machine for processing aluminum alloy doors and windows includes: a base 1, a worktable 2 mounted on the top of the base 1, a workpiece body 3 to be processed placed on the top of the worktable 2, a positioning plate 4 for positioning the workpiece body 3 mounted on one side of the worktable 2, an L-shaped rod 5 for pushing the workpiece body 3 mounted on the side of the worktable 2 away from the positioning plate 4, a first driving assembly for driving the worktable 2 to move installed inside both the base 1 and the worktable 2, and a clamping mechanism for holding the workpiece body installed inside the worktable 2. The clamping assembly of body 3, the worktable 2 is equipped with a second drive assembly for driving the L-shaped rod 5 to move, the worktable 2 is rotatably connected with a friction roller 61, the friction roller 61 is fixedly connected to the positioning plate 4, the end of the bidirectional toothed plate 32 away from the fixed threaded rod 41 is fixedly connected with a friction block 62, the friction block 62 is in contact with the friction roller 61, the top of the positioning plate 4 is located above the top of the worktable 2, the top of the base 1 is provided with an auxiliary slide groove 81, the bottom of the worktable 2 is rotatably connected with an auxiliary roller 82, the auxiliary roller 82 slides in the auxiliary slide groove 81.

[0030] It should be noted that when the worktable 2 moves, the auxiliary roller 82 also moves within the auxiliary chute 81, providing stability for the movement of the worktable 2.

[0031] Please see Figures 1 to 4 The first drive assembly includes a drive motor 21, a first gear 22 and a fixed rack 23. The drive motor 21 is fixedly connected inside the worktable 2. The output end of the drive motor 21 is fixedly connected to the first gear 22. The base 1 has a guide rail inside. The base 1 is located at the bottom of the guide rail and the fixed rack 23 is fixedly connected to it. The first gear 22 meshes with the fixed rack 23.

[0032] It should be noted that the rack is fixed inside the guide rail of base 1.

[0033] Please see Figures 1 to 5 The clamping assembly includes: a second gear 31, a bidirectional toothed plate 32, a fixed gear 33, a bidirectional threaded rod 34, and a clamping plate 35. The output end of the drive motor 21 is fixedly connected to the second gear 31. The bidirectional toothed plate 32 is slidably connected inside the worktable 2, and the bottom of the bidirectional toothed plate 32 meshes with the second gear 31. The fixed gear 33 is rotatably connected inside the worktable 2, and the fixed gear 33 meshes with the top of the bidirectional toothed plate 32. The bidirectional threaded rod 34 is fixedly connected to the axis of the fixed gear 33. Both ends of the bidirectional threaded rod 34 are threadedly connected to clamping plates 35 for clamping the object body 3. The second drive assembly includes: a fixed threaded rod 41 and a threaded rod 35. A fixed threaded rod 41 is fixedly connected to one end of the bidirectional toothed plate 32 away from the positioning plate 4. A threaded sleeve 42 is threadedly connected to the outer wall of the fixed threaded rod 41. The end of the threaded sleeve 42 away from the fixed threaded rod 41 is rotatably connected to the L-shaped rod 5. Fixed blocks 51 are symmetrically fixedly connected to both ends of the bidirectional toothed plate 32. A slide rod 52 is fixedly connected to one end of the fixed block 51. Slide plates 53 are symmetrically installed at both ends of the bidirectional toothed plate 32. The slide plates 53 slide within the corresponding two slide rods 52. Springs 54 are installed on the outer walls of multiple sets of slide rods 52. One end of the spring 54 is fixedly connected to the fixed block 51, and the other end of the spring 54 is fixedly connected to the slide plate 53.

[0034] It should be noted that: the two ends of the spring 54 are fixedly connected to the fixed block 51 and the slide rod 52 respectively. When the bidirectional toothed plate 32 moves to its end in one direction, the bidirectional toothed plate 32 no longer meshes with the second gear 31. The teeth fixedly connected to the bottom of the slider mesh with the second gear 31. The second gear 31 drives the slider to move through the teeth. The slider will only cause the spring 54 to contract and return to its original position. This process repeats. Therefore, the second gear 31 can no longer drive the bidirectional toothed plate 32 to move. When the second gear 31 rotates in the opposite direction, the second gear 31 will drive the teeth and the slider to move and cause the spring to... 54. During the stretching process, the slider touches one end of the slide bar 52 and moves the slide bar 52 a certain distance. The slide bar 52 moves the fixed block 51 and the bidirectional toothed plate 32 a certain distance. At this time, the teeth at the bottom of the bidirectional toothed plate 32 re-mesh with the teeth of the second gear 31. Auxiliary rods are fixedly connected to both sides of the worktable 2. The auxiliary rods pass through the corresponding clamping plates 35 and slide to connect with the clamping plates 35. The design of the auxiliary rods can restrict the rotation of the two clamping plates 35, so that when the bidirectional threaded rod 34 rotates, the clamping plate 35 can slide on the auxiliary rod and clamp the object body 3.

[0035] The working principle of the CNC end milling machine for aluminum alloy door and window processing provided by this utility model is as follows:

[0036] Object body 3 positioning and clamping:

[0037] The object body 3 is placed on the workbench 2. At this time, one end of the object body 3 is in contact with the positioning plate 4, and the other end is in contact with the L-shaped rod 5. The drive motor 21 of the first drive assembly is started. The drive motor 21 drives the first gear 22 to rotate. The first gear 22 meshes with the fixed rack 23 in the base 1. The movement of the first gear 22 on the fixed rack 23 causes the workbench 2 to move on the base 1. When the workbench 2 moves, the auxiliary roller 82 also moves in the auxiliary slide 81 to provide stability for the movement of the workbench 2. At the same time, the motor drives the second gear 31 to rotate. The second gear 31 meshes with the bottom of the bidirectional toothed plate 32. The second gear 31 has the same number of teeth as the first gear 22, and the diameter of the second gear 31 is twice that of the first gear 22. The second gear 31 drives the bidirectional toothed plate 32 to slide within the worktable 2. The top of the bidirectional toothed plate 32 meshes with the fixed gear 33, thereby driving the second gear 31 to rotate. The bidirectional threaded rod 34 at the axis of the second gear 31 rotates accordingly, driving the clamping plates 35 at both ends to move synchronously towards each other, firmly clamping the object body 3. During the movement of the clamping plates 35, when the bidirectional toothed plate 32 moves, the second drive assembly composed of the threaded rod and the threaded sleeve 42 pulls the L-shaped rod 5 towards the worktable 2, pushing the object body 3 out to one side of the worktable 2, making it convenient for the cutting device to cut. After the bidirectional toothed plate 32 finishes its stroke, the L-shaped rod 5 no longer pushes the object body 3, and at this time the clamping plate 35 completes the clamping work.

[0038] Positioning plate 4 rotates:

[0039] When positioning, the positioning plate 4 blocks the object body 3 from moving forward. When the bidirectional toothed plate 32 moves, it will push the friction block 62 to move. Since the friction block 62 is in frictional contact with the friction roller 61 and causes the friction roller 61 to rotate inside the worktable 2, the friction roller 61 drives the positioning plate 4 to rotate around the axis of the friction roller 61. The rotation of the positioning plate 4 is synchronized with the push-out movement of the object body 3. Therefore, the positioning plate 4 will not affect the movement of the object body 3.

[0040] Bidirectional toothed plate 32 limit:

[0041] Both ends of the bidirectional toothed plate 32 are fixedly connected to fixed blocks 51, and fixed blocks 51 are fixedly connected to slide rods 52. The slider moves on the slide rods 52. The two ends of the spring 54 are fixedly connected to the fixed blocks 51 and the slide rods 52 respectively. When the bidirectional toothed plate 32 moves to the end in one direction, the bidirectional toothed plate 32 no longer meshes with the second gear 31. The teeth fixedly connected to the bottom of the slider mesh with the second gear 31. The second gear 31 drives the slider to move through the teeth. The slider will only drive the spring 54 to contract and return to its original position. This process repeats, so the second gear 31 can no longer drive the bidirectional toothed plate 32 to move. When the second gear 31 rotates in the opposite direction, the second gear 31 will drive the teeth and the slider to move and stretch the spring 54. At this time, the slider touches one end of the slide rod 52 and drives the slide rod 52 to move a certain distance. The slide rod 52 drives the fixed blocks 51 and the bidirectional toothed plate 32 to move a certain distance. At this time, the teeth at the bottom of the bidirectional toothed plate 32 re-mesh with the teeth of the second gear 31. The bidirectional toothed plate 32 moves in the opposite direction and drives other components to complete the reset.
