Description

Technical Field

[0001] This invention relates to an aluminum processing equipment, and more particularly to an aluminum milling machining center. Background Technology

[0002] Modern aluminum alloy system doors and windows for buildings are primarily manufactured using aluminum processing centers for customized automated production. As customers demand increasingly higher levels of sealing performance and aesthetics from system doors and windows, the requirements for the hole dimensions of the aluminum materials composing the doors and windows are also becoming more stringent, especially for paired aluminum materials, such as the aluminum materials contained in the two vertical and two horizontal frames of an aluminum alloy window sash. Their hole positions need to correspond to each other to achieve high assembly accuracy after assembly. Existing automated aluminum processing centers mainly use roller feeding, with fixtures on the processing station to fix the aluminum materials before processing. Then, multiple milling, sawing, and drilling mechanisms mounted on robotic arms are used. Each processing mechanism is mounted on an independent robotic arm, resulting in high costs for both the robotic arms and programming. The processing accuracy of the aluminum materials mainly depends on the repeatability accuracy of the robotic arms, and each processing of different aluminum materials introduces new clamping errors, leading to a low pass rate and affecting the overall product quality. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides an aluminum milling machining center that can realize the simultaneous processing of two aluminum materials, and holes at different angles on the outer contour of the aluminum material can be completed in one clamping.

[0004] To solve the above-mentioned technical problems, embodiments of the present invention provide an aluminum milling machining center, including a milling assembly and a dual-material conveying mechanism. The milling assembly includes a base, a rotary table, and a first milling head and a second milling head disposed on the rotary table. The rotary table is rotatably disposed on the top of the base.

[0005] The dual-material conveying mechanism is located on one side of the milling assembly and includes a sliding base, an outer ring, an inner ring, a guide post, a gripper slide, a lead screw, a lead screw drive mechanism, a rotary drive mechanism, an upper gripper, and a lower gripper.

[0006] The sliding base is slidably mounted on the slide rail;

[0007] The outer ring is disposed on the sliding base, the inner ring is rotatably sleeved in the outer ring, and the rotation drive mechanism is connected to the inner ring and the outer ring to drive the inner ring to rotate relative to the outer ring;

[0008] The guide post and the lead screw are arranged laterally in the inner ring. The gripper slide is sleeved in the guide post and connected to the lead screw. The lead screw drive mechanism is used to drive the lead screw to rotate, thereby causing the gripper slide to slide along the guide post.

[0009] The upper jaw is located on one side of the jaw slide, and the lower jaw is located on the opposite side of the jaw slide. Both the upper jaw and the lower jaw are used to clamp aluminum materials.

[0010] A linkage rod is provided between the inner ring and the rotating disk. The linkage rod can drive the rotating disk to rotate horizontally by the same angle according to the rotation angle of the inner ring.

[0011] As an improvement to the above solution, the linkage rod is located in the bearing housing, with a first synchronous gear at one end and a second synchronous gear at the other end; the first synchronous gear meshes with the inner tooth surface of the inner ring, and the second synchronous gear meshes with the annular rack on the rotating disk.

[0012] As an improvement to the above solution, the rotating disk includes a lower rotating disk and an upper rotating disk. The upper rotating disk is connected to the lower rotating disk through a lifting cylinder. A guide rod and a sliding sleeve are also provided between the upper rotating disk and the lower rotating disk, and the guide rod extends into the sliding sleeve.

[0013] As an improvement to the above solution, the first milling head and the second milling head are symmetrically arranged on both sides of the rotation center of the upper rotary disk. The first milling head and the second milling head both include a milling body, a milling spindle and a milling head. The milling spindle is located in the milling body and the milling head is located on the top. The milling body can drive the milling spindle to rotate and extend.

[0014] As an improvement to the above solution, the upper and lower grippers have the same structure, both including a gripper seat, a fixed gripper, a movable gripper and a gripper air pump. The surface of the gripper seat is provided with a sliding groove. The fixed gripper is fixedly disposed on one side of the surface of the gripper seat. The movable gripper is slidably disposed in the sliding groove and connected to the gripper air pump.

[0015] As an improvement to the above solution, the gripper air pump is located in the slide groove and includes an air pump body and an air pump piston. The air pump body is connected to the gripper seat, and the air pump piston is connected to the movable gripper.

[0016] As an improvement to the above solution, the movable claw is also equipped with a clamping air pump. The piston rod of the clamping air pump extends out of the clamping surface of the movable claw and is connected to the clamping plate. The surface of the clamping plate is provided with transversely extending anti-slip strips.

The rack is provided on one side wall of the strip groove, and the rotary motor is provided on the inner ring and connected to the drive gear. The drive gear meshes with the rack.

[0019] Implementing the embodiments of the present invention has the following beneficial effects:

[0020] Two aluminum profiles are synchronously fed via a dual-material conveyor mechanism. During processing, the rotary table rotates synchronously with the inner ring of the dual-material conveyor mechanism, ensuring that the two aluminum profiles align with the first and second milling heads. This allows for simultaneous processing of both aluminum profiles, enabling the completion of holes at different angles on the outer contour of the aluminum profiles in a single clamping operation. Furthermore, the processing dimensions along the length of both aluminum profiles are guaranteed. This allows for the processing of high-precision aluminum products with lower machining accuracy, reducing equipment costs and improving yield. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0028] like Figures 1-3As shown, a specific embodiment of the present invention provides an aluminum milling machining center, including a milling assembly 100 and a dual material conveying mechanism 200. The milling assembly 100 includes a base 1, a rotary disk 2, and a first milling head 3 and a second milling head 4 disposed on the rotary disk 2; the rotary disk 2 is rotatably disposed on the top of the base 1.

[0029] The dual-material conveying mechanism 200 is located on one side of the milling assembly 100. The dual-material conveying mechanism 200 includes a sliding base 5, an outer ring 6, an inner ring 7, a guide post 8, a gripper slide 9, a lead screw 10, a lead screw drive mechanism 11, a rotary drive mechanism 12, an upper gripper 13, and a lower gripper 14. The sliding base 5 is slidably mounted on a slide rail 15. The outer ring 6 is mounted on the sliding base 5, and the inner ring 7 is rotatably fitted within the outer ring 6. The rotary drive mechanism 12 is connected to the inner ring 7 and the outer ring 6. The inner ring 7 is driven to rotate relative to the outer ring 6. The guide post 8 and the lead screw 10 are laterally arranged in the inner ring 7. The gripper slide 9 is sleeved in the guide post 8 and connected to the lead screw 10. The lead screw drive mechanism 11 is used to drive the lead screw 10 to rotate, thereby causing the gripper slide 9 to slide along the guide post 8. The upper gripper 13 is located on one side of the gripper slide 9, and the lower gripper 14 is located on the opposite side of the gripper slide 9. Both the upper gripper 13 and the lower gripper 14 are used to clamp aluminum materials. A linkage rod 16 is provided between the inner ring 7 and the rotating disk 2. The linkage rod 16 can drive the rotating disk 2 to rotate horizontally by the same angle according to the rotation angle of the inner ring 7.

[0030] Using the above structure, two aluminum materials are synchronously conveyed via a dual-material conveying mechanism 200. During processing, the rotary disk 2 and the inner ring 7 of the dual-material conveying mechanism 200 rotate synchronously, ensuring that the two aluminum materials correspond to the first milling head 3 and the second milling head 4. This enables simultaneous processing of the two aluminum materials, allowing holes at different angles on the outer contour of the aluminum materials to be completed in a single clamping operation. Furthermore, the processing dimensions along the length of the two aluminum materials are guaranteed. This allows for the processing of aluminum products with higher precision requirements using lower machining accuracy, reducing equipment costs and improving yield.

[0031] Preferably, the linkage 16 is disposed in the bearing seat 161, with a first synchronous gear 162 at one end and a second synchronous gear 163 at the other end; the first synchronous gear 162 meshes with the inner tooth surface of the inner ring 7, and the second synchronous gear 163 meshes with the annular rack 21 on the rotating disk 2.

[0032] In order to drive the first milling head 3 and the second milling head 4 to lift and lower as a whole, the rotary disk 2 includes a lower rotary disk 22 and an upper rotary disk 23. The upper rotary disk 23 is connected to the lower rotary disk 22 through a lifting cylinder 24. A guide rod 25 and a sliding sleeve 26 are also provided between the upper rotary disk 23 and the lower rotary disk 22. The guide rod 25 extends into the sliding sleeve 26.

[0033] Preferably, the first milling head 3 and the second milling head 4 are symmetrically arranged on both sides of the rotation center of the upper rotary disk 23. Both the first milling head 3 and the second milling head 4 include a milling body 31, a milling spindle 32, and a milling head 33. The milling spindle 32 is disposed within the milling body 31, and the milling head 33 is located at its top. The milling body 31 can drive the milling spindle 32 to rotate and extend / retract. The first milling head 3 and the second milling head 4 can be existing single-axis milling equipment, capable of milling the milling head 33 by rotating the milling spindle 32, and achieving individual control of the milling depth by driving the milling spindle 32 to extend / retract.

[0034] like Figure 4 As shown, preferably, the upper gripper 13 and the lower gripper 14 have the same structure, each including a gripper seat 131, a fixed gripper 132, a movable gripper 133 and a gripper air pump 134. The surface of the gripper seat 131 is provided with a sliding groove 135. The fixed gripper 132 is fixedly disposed on one side of the surface of the gripper seat 131. The movable gripper 133 is slidably disposed in the sliding groove 135 and connected to the gripper air pump 134.

[0035] The gripper air pump 134 is disposed in the slide groove 135 and includes an air pump body and an air pump piston. The air pump body is connected to the gripper seat 131, and the air pump piston is connected to the movable gripper 133. The gripper air pump 134 is disposed in the slide groove 135, which can make full use of the position of the fixed gripper 132 and also protect the easily damaged gripper air pump 134 from damage caused by collisions with the aluminum material.

[0036] Due to the significant variations in the outer contour and size of aluminum materials, recesses are provided on the clamping surfaces of both the movable claw 133 and the fixed claw 132 to ensure reliable clamping of aluminum materials with different shapes. A clamping air pump 136 is also provided on the movable claw 133. The piston rod of the clamping air pump 136 extends beyond the clamping surface of the movable claw 133 and connects to the clamping plate 137. The surface of the clamping plate 137 is provided with laterally extending anti-slip strips 138. When clamping aluminum materials with regular surfaces, the clamping air pump 136 can be used alone to drive the movable claw 133 closer to the fixed claw 132 to clamp the aluminum material. When the aluminum material surface has many recesses, in addition to using the clamping air pump 136 to drive the movable claw 133 closer to the fixed claw 132 to clamp the aluminum material, the clamping air pump 136 can also drive the clamping plate 137 to extend, further clamping and fixing the aluminum material through the smaller area of ​​the clamping plate 137. The anti-slip strip 138 can be made of rubber, which can fill the gaps on the surface of the aluminum material, so that the aluminum material is subjected to uniform force and avoid excessive clamping force causing deformation of the aluminum material. On the other hand, it can increase the friction, making the positioning of the aluminum material more reliable, and no additional clamps are needed to fix the aluminum material during the processing.

[0037] like Figure 5 As shown, preferably, the lead screw drive mechanism 11 includes a connecting vertical plate 111, a connecting bottom plate 112, and a lead screw drive motor 113. The connecting vertical plate 111 is fixedly connected to the inner ring 7, the connecting bottom plate 112 is located at the end of the connecting vertical plate 111, and the lead screw drive motor 113 is located on the connecting bottom plate 112 and connected to the lead screw 10.

[0038] The outer ring 6 has a strip groove 61 on its side. The rotary drive mechanism 12 includes a rack 121, a drive gear 122 and a rotary motor 123. The rack 121 is located on one side wall of the strip groove 61. The rotary motor 123 is located on the inner ring 7 and is connected to the drive gear 122. The drive gear 122 meshes with the rack 121.

[0039] like Figure 6 As shown, the sliding base 5 is provided with a passive wheel 51, a driving wheel 52 and a driving motor 53. The passive wheel 51 and the driving wheel 52 are both in contact with the slide rail 15, and the driving motor 53 is connected to the driving wheel 52.

[0040] This conveying equipment can simultaneously clamp and feed two aluminum profiles. During processing, the aluminum profiles can also be rotated as a whole as needed. Processing of two aluminum profiles can be completed in a single clamping operation, resulting in high precision and efficiency. Before clamping, the two aluminum profiles can be positioned at their front ends, ensuring they remain flush during processing. Subsequently, the two simultaneously processed aluminum profiles can be used in areas of aluminum alloy doors and windows requiring dimensional matching, improving component compatibility.

[0041] The working principle of this equipment is explained in detail below:

[0042] Initially, both dual-material conveying mechanisms 200 move to the feeding area. Aluminum is fed into the upper gripper 13 and lower gripper 14 via transfer rollers, and the front ends of the two aluminum pieces are aligned by a front limiting plate and other mechanisms. Next, the upper gripper 13 and lower gripper 14 of the front dual-material conveying mechanism 200, in conjunction with its own clamping plate 137, clamp the aluminum. The front dual-material conveying mechanism 200 moves forward. After the two dual-material conveying mechanisms 200 reach a predetermined distance, the upper gripper 13 and lower gripper 14 of the rear dual-material conveying mechanism 200, in conjunction with its own clamping plate 137, clamp the aluminum. The front and rear dual-material conveying mechanisms 200 synchronously translate forward and backward, translate left and right, and rotate to meet the feeding and processing angle requirements of the aluminum during the processing.

[0043] The distance between the first milling head 3 and the second milling head 4 is equal to the distance between the aluminum material on the two upper jaws 13 and the lower jaws 14. Therefore, during the rotation of the inner ring 7 of the dual material conveying mechanism 200, the rotary disk 2 driven by the linkage rod 16 can rotate synchronously with the inner ring 7 at the same angular velocity, ensuring that when a certain surface of the aluminum material faces the first milling head 3 or the second milling head 4, the corresponding first milling head 3 or the second milling head 4 can be located directly below the aluminum material, and can immediately drive the upper rotary disk 23 to rise through the lifting cylinder 24, and cooperate with the extension and retraction of the corresponding milling shaft 32 to perform processing feed and complete the corresponding milling process.

[0044] The above structure enables complex automated processing of aluminum materials using simple drilling and milling equipment, greatly reducing the manufacturing cost of processing equipment and meeting the needs of processing enterprises of different sizes.

[0045] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
