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

[0029] The double-material conveying mechanism 200 is arranged on one side of the milling assembly 100, and the double-material conveying mechanism 200 includes a sliding base 5, an outer ring 6, an inner ring 7, a guide column 8, a clamping jaw slide 9, a screw 10, a screw drive mechanism 11, a rotation drive mechanism 12, an upper clamping jaw 13 and a lower clamping jaw 14. The sliding base 5 is slidably arranged on the slide rail 15; the outer ring 6 is arranged on the sliding base 5, the inner ring 7 is rotatably sleeved in the outer ring 6, and the rotation drive mechanism 12 is connected to the inner ring 7 and the outer ring 6. The guide post 8 and the screw 10 are arranged in the inner ring 7 horizontally, the clamp slide 9 is sleeved in the guide post 8 and connected with the screw 10, and the screw drive mechanism 11 is used to drive the screw 10 to rotate, thereby driving the clamp slide 9 to slide along the guide post 8; the upper clamp 13 is arranged on one side of the clamp slide 9, and the lower clamp 14 is arranged on the opposite side of the clamp slide 9, and the upper clamp 13 and the lower clamp 14 are both used to clamp aluminum. A linkage rod 16 is arranged between the inner ring 7 and the rotating disk 2, and the linkage rod 16 can drive the rotating disk 2 to rotate synchronously and horizontally by the same angle according to the rotation angle of the inner ring 7.

[0030] With the above structure, two aluminum materials are synchronously conveyed by the double-material conveying mechanism 200. During the processing, the rotating disk 2 and the inner ring 7 of the double-material conveying mechanism 200 rotate synchronously, so that the two aluminum materials correspond to the first milling head 3 and the second milling head 4, and the synchronous processing of the two aluminum materials can be achieved. The holes at different angles on the outer contour of the aluminum material can be completed by one clamping, and the processing dimensions of the length direction of the two aluminum materials can be guaranteed. It is allowed to use lower processing accuracy to process aluminum products with higher precision requirements, which can reduce equipment costs and improve the yield rate.

[0031] Preferably, the linkage rod 16 is arranged in a bearing seat 161, with a first synchronization gear 162 at one end and a second synchronization gear 163 at the other end; the first synchronization gear 162 is meshed with the inner tooth surface of the inner ring 7, and the second synchronization gear 163 is meshed 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 rise and fall as a whole, the rotating disk 2 includes a lower rotating disk 22 and an upper rotating disk 23. The upper rotating disk 23 is connected to the lower rotating disk 22 through a lifting cylinder 24. A guide rod 25 and a sliding sleeve 26 are also provided between the upper rotating disk 23 and the lower rotating 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 rotating disk 23, and the first milling head 3 and the second milling head 4 each include a milling body 31, a milling shaft 32 and a milling head 33, the milling shaft 32 is arranged in the milling body 31, the milling head 33 is arranged on the top, and the milling body 31 can drive the milling shaft 32 to rotate and extend. The first milling head 3 and the second milling head 4 can be existing one-axis milling equipment, which can realize the milling work of the milling head 33 by rotating the milling shaft 32, and realize the individual control of the milling depth by driving the milling shaft 32 to extend.

[0034] like Figure 4 As shown, preferably, the upper jaw 13 and the lower jaw 14 have the same structure, both comprising a jaw seat 131, a fixed jaw 132, a movable jaw 133 and a jaw air pump 134, a slide groove 135 is provided on the surface of the jaw seat 131, the fixed jaw 132 is fixedly arranged on one side of the surface of the jaw seat 131, and the movable jaw 133 is slidably arranged in the slide groove 135 and connected to the jaw air pump 134.

[0035] The clamping jaw air pump 134 is arranged in the slide groove 135, and includes an air pump body and an air pump piston, wherein the air pump body is connected to the clamping jaw seat 131, and the air pump piston is connected to the movable jaw 133. The clamping jaw air pump 134 is arranged in the slide groove 135, which can make full use of the position of the fixed jaw 132 and protect the easily damaged clamping jaw air pump 134 from being damaged by the collision of the aluminum material.

[0036] Since the outer contour shape and size of aluminum materials vary greatly, in order to reliably clamp aluminum materials of different shapes, the clamping surfaces of the movable claw 133 and the fixed claw 132 are both provided with recessed portions. The movable claw 133 is also provided with a clamping air pump 136, and the piston rod of the clamping air pump 136 extends out of the clamping surface of the movable claw 133 and is connected to the clamping plate 137. The surface of the clamping plate 137 is provided with a laterally extending anti-slip strip 138. When clamping aluminum materials with regular surfaces, the clamping air pump 136 can be used alone to drive the movable claw 133 to approach the fixed claw 132 to clamp the aluminum material. When the aluminum material surface has more recessed surfaces, in addition to using the clamping air pump 136 to drive the movable claw 133 to approach the fixed claw 132 to clamp the aluminum material, the clamping air pump 136 can also be used to drive the clamping plate 137 to extend, and the aluminum material can be further clamped and fixed by the clamping plate 137 with a smaller area. The anti-slip strip 138 can be made of rubber. On the one hand, it can fill the gaps on the surface of the aluminum material, so that the aluminum material is evenly stressed and prevent the aluminum material from being deformed due to excessive clamping force. On the other hand, it can increase friction, making the positioning of the aluminum material more reliable, and no additional clamps are required to fix the aluminum material during the processing process.

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

[0038] A strip groove 61 is provided on the side of the outer ring 6, and the rotation drive mechanism 12 includes a rack 121, a driving gear 122 and a rotating motor 123. The rack 121 is provided on a side wall of the strip groove 61, and the rotating motor 123 is provided on the inner ring 7 and connected to the driving gear 122. The driving gear 122 is meshed 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 clamp and feed two aluminum materials at the same time. During the processing, the aluminum materials can be rotated as a whole as needed. The processing of two aluminum materials can be completed in one clamping, with high processing accuracy and efficiency. The front end of the two aluminum materials can be positioned before clamping, and the two aluminum materials can be kept flush during the processing. The two aluminum materials processed at the same time can be used in the parts of aluminum alloy doors and windows that require size matching, thereby improving the matching of components.

[0041] The working principle of this device is described in detail below:

[0042] In the initial state, both double-material conveying mechanisms 200 move to the feeding area, and the aluminum material is fed into the upper clamping jaw 13 and the lower clamping jaw 14 through the transmission roller, and the front end limit plate and other mechanisms ensure that the front ends of the upper and lower aluminum materials are aligned. Then, the upper clamping jaw 13 and the lower clamping jaw 14 of the front double-material conveying mechanism 200 cooperate with their own clamping plates 137 to clamp the aluminum material, and the front double-material conveying mechanism 200 moves forward. When the front and rear double-material conveying mechanisms 200 reach a predetermined distance, the upper clamping jaw 13 and the lower clamping jaw 14 of the rear double-material conveying mechanism 200 cooperate with their own clamping plates 137 to clamp the aluminum material. The front and rear double-material conveying mechanisms 200 synchronously translate forward and backward, left and right, and rotate to meet the feeding requirements and processing angle requirements of the aluminum material during the processing process.

[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 double-material conveying mechanism 200, the rotating 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 is facing 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 just below the aluminum material, and the upper rotating disk 23 can be immediately driven to rise by the lifting cylinder 24, and the corresponding milling shaft 32 can be extended and retracted to perform processing and feeding to complete the corresponding milling process.

[0044] By adopting the above structure, simple drilling and milling equipment can be used to perform complex automated processing on aluminum materials, which greatly reduces the manufacturing cost of the processing equipment and meets the needs of processing companies of different sizes.

[0045] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
