The support seat 1-1 is rotatably connected to the frame 7 and can be rotated a certain angle in the horizontal direction, which is convenient for the operator to operate. The lower end of the support rod 1-2 is rotatably connected to the support seat 1-1, and the upper end of the support rod 1-2 is rotatably connected to the support platform 1-3. The length of the support rod 1-2 can be adjusted. By adjusting the length of the support rod, the adjustment requirements of different heights of the support platform 1-3 can be achieved to adapt to the height coordination of aluminum alloy profiles of different specifications and other devices on the workbench.

[0034] The punching and riveting indexing device 4 is composed of two groups, which are symmetrically arranged on the upper plane of the workbench 2 at 90 degrees. The device includes a punching and riveting mechanism and a indexing mechanism. The two mechanisms are coaxially connected by a connecting shaft 4-2. A pin plate 4-1 is installed at the front of the punching and riveting bracket 4-8. A plurality of pins are installed on the pin plate. The installation method is a gap connection. The pins can be separated from the mounting holes of the pin plate under the ejection force of the ejector rod 4-7. The connecting shaft 4-2 passes through the axle box and is connected to the indexing mechanism 4-3. The indexing mechanism 4-3 is connected to the punching and riveting head 4-5 through the connecting rod transmission mechanism 4-4. The lower part of the punching and riveting head is installed with a transmission shaft 4-6 that passes through the workbench. The transmission shaft is connected to the synchronous feeding device 6.

The feeding cylinder 6-2 drives the feeding plate 6-3 forward, and the feeding plate drives the transmission shaft 4-6 forward through the guide groove, thereby driving the punching and riveting indexing device 4 forward. When the punching and riveting indexing device 4 moves forward, it pushes the pins into the mounting holes of the aluminum alloy profile and the angle code C. When the feeding cylinder 6-2 returns to its position, it drives the punching and riveting indexing device 4 backward. The movement of the indexing mechanism drives the pin disk to rotate through the connecting shaft to prepare for the next process.

The rear of the lifting seat is connected to an inner positioning angle plate 9-3. The lifting seat is driven by the cylinder to move up and down, thereby realizing the height adjustment of the positioning angle plate. A horizontal moving seat is installed inside the lifting seat, and the horizontal moving seat is connected to a horizontal cylinder 9-5.

[0038] The height position adjustment and angle combination process of the present invention is as follows:

[0039] (1) Adjust the height of the synchronous support device 3 and the position of the ejector rods 4-7;

[0040] First, the profile A to be assembled is placed on the synchronous supporting device 3, and the height of the synchronous supporting device 3 is adjusted to be the same as the horizontal height of the supporting frame 1.

[0041] (2) Adjust the position of the pin plate 4-1;

[0042] First, loosen the relevant screws fixed on the pin plate 4-1, align the round hole on the pin plate 4-1 with the top rod 4-8, and then tighten the relevant screws on the pin plate 4-1.

[0043] (3) Adjust the inner positioning angle plate 9-3 in the inner positioning device and the outer positioning angle plate 5-6 in the outer positioning device so that they coincide with the inner and outer facades of the profile respectively and the upper plane of the bracket coincides with the upper plane of the 1st plate;

[0044] Place the profile with the corner code inserted on the synchronous supporting device 3, control the foot valve in the foot box of the control system 8 to operate, lift the lifting seat 9-2 in the front positioning device to a fixed position, turn the operating handle 5-9 in the rear positioning device to adjust the inner side surface of the outer positioning angle plate 5-6 in the rear positioning device to overlap with the outer corner facade of the profile and lock it.

[0045] (4) Adjust the distance between the pin plate 4-1 and the outer surface of the profile;

[0046] By rotating the adjusting screw in the synchronous feeding device 6, the push plate 6-3 moves forward or backward accordingly, driving the pin plate 4-1 in the punching and riveting indexing device 4 to move forward or backward through the transmission shaft 4-6. When the distance between the pin plate 4-1 and the outer vertical surface of the profile reaches the requirement, the nut in the synchronous feeding device 6 is locked.

[0047] (5) Adjust the position of the pressing cylinder 5-4;

[0048] Loosen the adjustable handle and adjust the clamping cylinder 5-4 to a suitable position according to the profile height, and then lock the adjustable handle.

[0049] (6) Adjust the side positioning position;

[0050] Loosen the control handle of the side support plate, move the side support plate along the long groove direction, let its side elevation overlap with the outer side of the profile, and then lock the control handle.

[0051] (5) Install the pins;

[0052] Step on the foot valve, and all devices will return to their original positions driven by the cylinder; remove the pin plates in the punching and riveting and indexing devices, fill them with pins, and then install them again.

[0053] (6) Angle combination;

[0054] After the above work is ready, put the profile on the supporting device 3, step on the foot valve, and the cylinders will act in sequence; the sequence of actions is controlled by the delay valve, and the actions are as follows: cylinder 9-4 rises, the horizontal cylinder 9-5 pushes out the piston rod, the inner positioning angle plate 9-3 rises and moves forward, the clamping cylinder 5-4 clamps the profile, the feed cylinder 6-2 pushes the punch rivet head forward, and the top plate fixed with the punch rivet head pushes the top rod 4-7, Push rod 4-7 pushes the pin in the pin disk to insert into the profile and the angle code. At this point, one sample angle of the profile has been assembled, and the corresponding pin in the pin disk has been inserted into the profile; step on the foot valve again, and the cylinders act in sequence, the cylinders retreat, and the parts connected to them also retreat, and push rod B also retreats under the action of the spring; the impact shaft fixed with the punch rivet head retreats to a certain distance and drives the indexing device together with the connecting rod assembly to drive the pin disk to rotate a corresponding degree, so that the hole with the pin on the pin disk is aligned with the push rod 4-7, and the above actions are repeated to complete the angle assembly work of the other angle of the profile.
