This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0033] like Figure 1 As shown, the H-shaped aluminum alloy profile automatic production line of the present invention includes a frame, on which a pulling device A, a milling device B and a receiving device C are installed in sequence.

[0034] like Figure 2-4 As shown, the material pulling device A comprises a reciprocating driving mechanism mounted on a frame, and a material pulling clamping mechanism for clamping the web of the H-shaped aluminum alloy profile is mounted on the reciprocating driving mechanism.

[0035] The reciprocating drive mechanism includes a guide rail A101 and a rack A102 mounted on a frame, the rack A102 is located on one side of the guide rail A101, a slidably mounted support plate A103 is mounted on the support plate A103, a material pulling clamping mechanism and a material pulling motor A104 are mounted on the support plate A103, the motor shaft of the material pulling motor A104 is connected to a gear A105 located below the support plate A103, and the gear A105 is meshed and connected to the rack A102. When the material pulling motor A104 drives the gear A105 to rotate, the support plate A103 and the material pulling clamping mechanism above it can be driven to move forward or backward along the guide rail.

[0036] The above-mentioned material pulling and clamping mechanism includes a fixed material clamping plate A201 installed on the support plate A103, and the fixed material clamping plate A201 is connected to a movable material clamping plate A202 located above it through a lifting drive mechanism. The clamping ends of the fixed material clamping plate A201 and the movable material clamping plate A202 are provided with at least one ( Figure 2 , 3 There are 3 of them) A203 clamping teeth for clamping the web of H-shaped aluminum alloy profiles.

[0037] The lifting drive mechanism is composed of a driving part and a guiding part, wherein the driving part includes a first door-shaped frame A301 connected to the fixed clamping plate A201, and a clamping cylinder A302 located above the movable clamping plate A202 and connected to the two is installed on the first door-shaped frame A301; the guiding part includes a guide column A303 connected to the fixed clamping plate A201 at one end and passing through the movable clamping plate A202 and extending upward at the other end, and a linear bearing A304 fixedly connected to the movable clamping plate A202 is sleeved on the guide column A303, and a return spring A305 located between the fixed clamping plate A201 and the movable clamping plate A202 is also sleeved on the guide column A303. Usually, four guide columns A303 are arranged in a rectangular symmetrical structure, and correspondingly, four linear bearings A304 and return springs A305 thereon are also arranged, and the first door-shaped frame A301 is located between the guide columns A303. When the clamping cylinder A302 is working, the fixed clamping plate A201 and the movable clamping plate A202 fit closely together to clamp the H-shaped aluminum alloy profile; when the clamping cylinder A302 returns to its original position, the fixed clamping plate A201 and the movable clamping plate A202 will separate under the action of the return spring A305, so that the H-shaped aluminum alloy profile can be placed or taken out.

[0038] When the fixed clamping plate A201 and the movable clamping plate A202 are tightly fitted together, the engaging teeth A203 at the clamping end thereof can firmly clamp the web of the H-shaped aluminum alloy profile.

When there are multiple engaging teeth A203, they are arranged side by side and spaced apart at the clamping ends of the fixed clamping plate A201 and the movable clamping plate A202. Preferably, the width of the upper or lower teeth is slightly smaller than the width of the web of the H-shaped aluminum alloy profile, and the spacing between adjacent clamping teeth A203 is the width when two H-shaped aluminum alloy profile vertical plates are set adjacent to each other, so that multiple H-shaped aluminum alloy profiles can be closely arranged when clamped to avoid displacement.

[0039] like Figure 5 , 6 As shown, the above-mentioned gear milling device B includes a gear milling clamping mechanism and a gear milling mechanism installed on a frame, which can be used to place a row of H-shaped aluminum alloy profiles ( Figure 5 The top surface of the lower notch of three H-shaped aluminum alloy profiles arranged side by side is milled in batches in the X direction, which not only improves the milling efficiency but also has high processing accuracy.

[0040] The above-mentioned milling gear clamping mechanism includes an X-axis clamping mechanism and a Z-axis clamping mechanism. The X-axis clamping mechanism includes a fixed stopper B101 installed on the frame and a movable stopper B103 connected to the X-axis oil cylinder B102.

Under the action of the X-axis oil cylinder B102, the two can firmly clamp the row of H-shaped aluminum alloy profiles along the X direction; the Z-axis clamping mechanism is located above the row of H-shaped aluminum alloy profiles, and includes a second door-shaped Frame, a Z-axis cylinder B201 and a Z-axis clamping plate B202 connected thereto are installed on the top wall of the second door-type frame, and a plurality of protrusions B203 adapted to the grooves of the rows of H-shaped aluminum alloy profiles are arranged at intervals on the lower surface of the Z-axis clamping plate B202. When the X-axis clamping mechanism clamps the rows of H-shaped aluminum alloy profiles in X direction, the Z-axis cylinder B201 is actuated, and the Z-axis clamping plate B202 is pressed downward to press the protrusions B203 into the grooves of the rows of H-shaped aluminum alloy profiles, thereby realizing the Z-direction clamping of the rows of H-shaped aluminum alloy profiles.

[0041] The above-mentioned milling gear mechanism is located on the frame below the rows of H-shaped aluminum alloy profiles, and includes a horizontal fixed plate B301 for installing an X-axis push-pull assembly and a tool assembly, a horizontal sliding plate B303 connected to the X-axis guide rail B302 is installed on the horizontal fixed plate B301, an X-axis motor B304 is installed on the frame leg on one side of the horizontal sliding plate B303, and the X-axis motor B304 and the horizontal sliding plate B303 are connected through a ball screw B305 to form an X-axis push-pull assembly.

After the milling gear clamping mechanism clamps the rows of H-shaped aluminum alloy profiles in the X and Z directions, the Y-axis motor B405 is started to make the Y-axis rotating shaft B403 drive the toothed cutter wheel B404 to rotate. At the same time, the horizontal sliding plate B303 is driven by the X-axis motor B304 to reciprocate along the X direction, so that the toothed cutter wheel B404 performs X-direction milling on the top surface of the lower notch of the rows of H-shaped aluminum alloy profiles. After completion, the rows of H-shaped aluminum alloy profiles are moved forward along the Y direction, and the above steps are repeated to perform the next section of X-direction milling.

[0042] like Figure 7-9As shown, the material receiving device C includes an adjusting component and a conveying component which are matched and mounted on the frame. The adjusting components are arranged in pairs and arranged in sequence along the transmission direction of the H-shaped aluminum alloy profile. A conveying component is installed between each pair of adjusting components. Each adjusting component is composed of a fixing part and a lifting part. The fixing part is usually an L-shaped bracket C101 installed on the frame, on which two horizontal screws C102 are arranged vertically at intervals; the lifting part is a connecting piece C203 with a vertical long hole C201 and a mounting hole C202, and the vertical long hole C201 is located below the mounting hole C202.

Each conveying assembly includes a roller C301 and a support shaft C302 at both ends thereof. The support shaft C302 is rotatably connected to the mounting hole C202 of the connecting plate C203 through a bearing.

The top surface height of the roller C301 is matched with the bottom surface height of the H-shaped aluminum alloy profile. The length of the roller C301 is 2-5 times the width of a single H-shaped aluminum alloy profile, which is convenient for batch connection and improves production efficiency.
