Description

Technical Field

[0002] Aluminum profiles are metal materials with specific cross-sectional shapes, with aluminum as the main component, made through extrusion, rolling and other processes. They are widely used in construction, industrial manufacturing, transportation and other fields.

[0003] Aluminum profiles are usually long strips. When preparing them into door and window frames, they first need to be cut into 45° angles at the corners.

[0017] Beneficial effects

[0018] 1. The present invention realizes the clamping of the welding right-angled edges by providing two clamping mechanisms. The two clamping mechanisms move synchronously to realize the movable splicing of the two welding right-angled edges. At the same time, an L-shaped bottom plate is slidably provided on the clamping mechanism. The L-shaped bottom plate cooperates with the first spring to realize adaptive adjustment of the two welding edges. When one right-angled edge reaches the welding point and the other edge has not yet reached the welding point, the first spring is compressed to realize the relative stillness of the U-shaped clamping piece until both sides reach the welding position. The welding is performed after automatic splicing, which has higher splicing efficiency, avoids repeated adjustments, and saves time.

[0019] 2. The present invention is provided with a rotating mechanism, in which a circular ring is provided. The circular ring cooperates with the clamping airbag to clamp the welded right-angled edge. At the same time, the clamping airbag can also lift the welded right-angled piece before clamping and flip it over, avoiding manual flipping and saving time and manpower.

[0020] 3. The present invention realizes the movement of the clamping plate in the clamping mechanism by providing an auxiliary part and a movable plate. Before loading, the matching block on the clamping mechanism is moved into the auxiliary part to open the clamping plate. The operator can directly place the welding edge on the U-shaped clamping part. As the clamping mechanism moves, automatic clamping is achieved. After welding one side, the clamping plate can also be opened by moving the movable plate, which is convenient for turning over the welded part and loading and unloading the welded part with the auxiliary part.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] like Figures 1 to 11As shown, an aluminum profile processing and welding device provided by an embodiment of the present invention is mainly used to weld 45° aluminum profiles into right angles, including a workbench 1, a plurality of supporting legs 2 are fixedly provided at the bottom end of the workbench 1, a sliding member 3 is slidably provided on the side of the workbench 1, a telescopic cylinder 5 and a telescopic rod 4 are fixedly provided on the sliding member 3, a mounting bracket 6 is fixedly provided at the output end of the telescopic cylinder 5 and the extended end of the telescopic rod 4, a mounting bracket 6 is rotatably provided with a mounting groove 7, a limiting slide bar 8 is fixedly provided in the mounting groove 7, and a first threaded rod 9 is rotatably provided, a welding mechanism 11 is threadedly matched with the first threaded rod 9, the welding mechanism 11 is slidably connected to the limiting slide bar 8, and a first motor 12 is provided at the rotation connection between the mounting bracket 6 and the mounting groove 7, and the first motor 12 is fixed to the mounting bracket 6 A fixed connection is formed, and the first motor 12 drives the mounting groove 7 and the mounting bracket 6 to rotate. A second motor 10 is also fixed to one end of the mounting groove 7. The output end of the second motor 10 is connected to the first threaded rod 9. In this embodiment, the welding mechanism 11 can adopt laser welding equipment. The telescopic cylinder 5 controls the mounting bracket 6 to move up and down to realize the height change of the welding mechanism 11, and adjusts the welding mechanism 11 to a suitable welding position for welding. At the same time, the second motor 10 drives the first threaded rod 9 to rotate to realize the movement of the welding mechanism 11 in the mounting groove 7. The sliding of the sliding member 3, the rotation of the mounting groove 7 and the movement of the welding mechanism 11 in the mounting groove 7 further realize the change of the position of the welding mechanism 11, which is convenient for the welding mechanism 11 to perform welding in different orientations.

[0036] like Figure 1 As shown, the workbench 1 is further provided with a first slide 24, and a second slide 14 is symmetrically provided on both sides of the first slide 24. The two second slides 14 are distributed at right angles. A right-angle piece 13 is slidably provided on the first slide 24, and the right-angle piece 13 can move in the first slide 24. A clamping mechanism 16 is slidably provided on the two second slides 14, and a baffle 15 is fixed on the two second slides 14. A movable plate 19 is slidably provided on the adjacent sides of the two second slides 14. A movable groove 21 is provided below the two movable plates 19 on the workbench 1, and a rotating groove 21 is provided in the movable groove 21. A second threaded rod 20 is provided, and the two second threaded rods 20 are respectively threadedly engaged with the two movable plates 19. A first gear box 22 is also installed on the workbench 1. The top of the first gear box 22 is connected to a rotating rod 23. Three mutually meshing bevel gears are provided in the first gear box 22. The three bevel gears are respectively fixedly connected to the two second threaded rods 20 and the rotating rod 23. When the rotating rod 23 is manually rotated, the meshing transmission between the bevel gears can realize the synchronous rotation of the two second threaded rods 20, and further realize the movement of the two movable plates 19 in the movable groove 21.

[0037] During the right-angle welding process of aluminum profiles, the operator needs to hold the two right-angle edges, splice the 45° welding surfaces and then weld. This process sometimes requires repeated adjustments to ensure that the welding surfaces are spliced ​​correctly. This embodiment solves the above problem by providing two sliding clamping mechanisms 16.

[0038] like Figure 2-4 As shown, the clamping mechanism 16 includes an L-shaped base plate 1601, a third sliding groove 1602 is provided on the L-shaped base plate 1601, a U-shaped clamping member 1610 is slidably provided on the third sliding groove 1602, the U-shaped clamping member 1610 and the L-shaped base plate 1601 are connected by a first spring 1603, a notch 1611 is further provided on one side of the U-shaped clamping member 1610, a clamping plate 1605 is slidably provided in the notch 1611, the clamping plate 1605 and the U-shaped clamping member 1610 are connected by a second spring 1612, a bending rod 1606 is further fixed to the top of the clamping plate 1605, and a matching block 1607 is fixed to the top of the bending rod 1606, as shown in FIG. Figure 4 The mating block 1607 shown is a trapezoidal structure, and a cylindrical slide rod 1608 is fixed on the splint 1605. A circular plate 1609 is fixed at the end of the cylindrical slide rod 1608. The cylindrical slide rod 1608 is slidingly connected to the side wall of the U-shaped clamping member 1610, and a sliding block 1604 is also fixed on the side end of the L-shaped bottom plate 1601.

[0039] like Figure 8 As shown, the sliding modes of the clamping mechanisms 16 in the two second slides 14 are consistent. Taking the sliding mode of one of the clamping mechanisms 16 as an example, specifically, a third threaded rod 1613 is rotatably provided in the second slide 14, and the third threaded rod 1613 is slidably connected to the sliding block 1604 on the clamping mechanism 16. One end of the third threaded rod 1613 is coaxially and fixedly provided with a first pulley 1614. A second gear box 1618 is also fixedly provided at the bottom end of the workbench 1. A cylindrical shaft 1616 is rotatably provided on the second gear box 1618, and a second pulley 1615 is fixedly provided at the end of the cylindrical shaft 1616. The first pulley 1614 and the second pulley 1615 are connected by a first synchronous belt 1617, as shown in FIG. Figure 10 and Figure 11 As shown, three mutually meshing bevel gears are provided in the second gear box 1618, two of which are coaxial with and fixedly connected to the two cylindrical shafts 1616 (the two cylindrical shafts 1616 here are respectively on the two clamping mechanisms 16, and are also distributed at right angles), and the other bevel gear is connected to a third motor 1619, which drives one of the bevel gears to rotate, and realizes the synchronous rotation of the two cylindrical shafts 1616 through the meshing transmission between the bevel gears. The two cylindrical shafts 1616 then drive the rotation of the two third threaded rods 1613 through the first synchronous belt 1617, thereby finally realizing the movement of the two clamping mechanisms 16.

[0040] When in use, the right-angled edge to be welded is placed in the U-shaped clamping piece 1610, and the clamping plate 1605 cooperates with the second spring 1612 to clamp the right-angled edge. After the right-angled edge is fixed, the two third threaded rods 1613 are driven to rotate by the third motor 1619 to realize the forward movement of the U-shaped clamping piece 1610, and the right-angled edge is pushed forward along the second slide groove 14. Before this, the right-angled piece 13 can be slid to the specified position. During the forward movement of the right-angled edge, it will gradually contact the edge of the right-angled piece 13 until it reaches its right-angle point. After the two right-angled edges of the aluminum profiles are spliced ​​together to form a right angle, they stop moving and the welding mechanism 11 is started for welding.

[0041] In actual operation, there is a problem that the two U-shaped clamping members 1610 have inconsistent clamping positions on the two right-angled sides or inconsistent lengths of the two right-angled sides, which may result in a situation where one right-angled side reaches the welding point while the other side has not yet reached the welding point. For this problem, this embodiment solves the above problem by providing a first spring 1603 to cooperate with the U-shaped clamping member 1610. Specifically, when one of the right-angled sides reaches the welding point and contacts the right-angled member 13 (at this time, the other right-angled side has not yet arrived and the third threaded rod 1613 continues to rotate), the right-angled member 13 will block the right-angled side that reaches the welding point first, and the L-shaped bottom plate 160 1 continues to move, and the U-shaped clamping piece 1610 encounters resistance and compresses the first spring 1603, so that the U-shaped clamping piece 1610 drives the upper right-angled side thereof to slide a certain distance on the third slide groove 1602. When the other right-angled side reaches the welding point and contacts the right-angled piece 13, the two right-angled sides are spliced ​​to form a right angle. At this time, the welding mechanism 11 is started to weld, avoiding repeated manual adjustment of the clamping point of the right-angled side and saving time. During the welding process, it is only necessary to roughly place the right-angled side to be welded on the U-shaped clamping piece 1610, and the first spring 1603 can achieve alignment of the welding point by self-adaptation.

[0042] In the case where the clamping plate 1605 needs to be adjusted to clamp the right angle side, this embodiment solves this problem by providing an auxiliary member 18, such as Figure 5-7 As shown, the side of the second chute 14 is also fixed with an auxiliary member 18, the auxiliary member 18 includes a vertical rod 1801, the top of the vertical rod 1801 is fixed with two inclined plates 1802, the two inclined plates 1802 and the vertical rod 1801 connection end is a trapezoidal structure (as shown in FIG. Figure 6During use, the clamping mechanism 16 is moved to its rearmost end. During this movement, the mating block 1607 gradually moves to a position between the two inclined plates 1802, with the oblique edges of the mating block 1607 abutting against the inclined plates 1802. As the clamping mechanism 16 continues to move, the mating block 1607 moves along the inclined plates 1802. At this time, the clamping plate 1605 compresses the second spring 1612, causing the clamping plate 1605 to automatically open. The operator then simply places the weld edge within the U-shaped clamping member 1610. As the U-shaped clamping member 1610 moves forward, the mating block 1607 separates from the inclined plates 1802, ultimately achieving clamping of the weld edge.

[0043] During the operation, after welding one side of the aluminum profile, it needs to be manually turned over before welding the other side. This embodiment solves the above problem through the following structure: Figure 8 As shown, the front end of one of the second slides 14 is also provided with a rotating mechanism 17, which includes a circular ring 1701, a clamping airbag 1704 is provided in the circular ring 1701, the clamping airbag 1704 is connected to the air pump 1705, and the air pump 1705 is fixedly installed on the circular ring 1701. A fourth motor 1707 is also fixedly provided at the bottom of the workbench 1, and the output end of the fourth motor 1707 is fixedly connected to the first gear 1706. A second gear 1703 is fixedly provided on the outer side of the circular ring 1701, and the first gear 1706 and the second gear 1703 are transmitted. A rectangular groove is provided on the workbench 1 below the circular ring 1701, and limit plates 1702 are fixedly provided on both sides of the rectangular groove. The limit plates 1702 on both sides are slidably connected to the circular ring 1701. Specifically, an annular slide groove is provided on both sides of the circular ring 1701, and the limit plates 1702 slide in the annular slide groove when the circular ring 1701 rotates.

[0044] During use, when the clamping mechanism 16 drives one of the right-angled edges to move forward, it will pass through the circular ring 1701. After the two welding edges complete the welding on one side, the air pump 1705 works to clamp the clamping airbag 1704 to clamp the welding parts inside it. The clamping airbag 1704 can be set to a structure with a large amount of inflation at the bottom, which can lift the welding parts a certain distance to facilitate the flipping of the welding parts. At this time, the rotating rod 23 is manually rotated, and the rotating rod 23 is driven by the first gear box 22 to realize the movement of the two movable plates 19. At the beginning, the movable plate 19 is located between the circular plate 1609 and the side wall of the U-shaped clamping member 1610. As the movable plate 19 moves, the movable plate 19 contacts the circular plate 1609 and pulls it outward, that is, the two clamping mechanisms 16 loosen the welding parts, and the fourth motor 1707 drives the first gear 1706 to rotate, and the first gear 1706 drives the synchronous rotation of the circular ring 1701 to flip the welding parts and cooperate with the welding mechanism 11 to perform welding on the other side.

[0045] A welding method for an aluminum profile welding device comprises the following steps:

[0046] S1: First, the right-angled edge to be welded is placed in the clamping mechanism 16, and the right-angled piece 13 is slid to the specified position. The third threaded rod 1613 is rotated to realize the movement of the U-shaped clamping piece 1610, and the first spring 1603 is used to realize the adaptive adjustment of the two right-angled edges. After the splicing is completed, the welding mechanism 11 is started to weld;

[0047] S2: After one side is welded, the weldment is located in the circular ring 1701 and is lifted and clamped by the clamping airbag 1704. At this time, the rotating rod 23 is manually adjusted, the movable plate 19 contacts the circular plate 1609 and pulls it outward, the clamping mechanism 16 releases the weldment, and then the weldment is flipped by rotating the circular ring 1701, and the welding mechanism 11 is used to achieve welding on the other side.
