Description

Technical Field

[0001] The invention relates to the technical field of aluminum building material welding, and in particular to a high-efficiency aluminum building material welding device and method. Background Art

[0002] Auxiliary devices are required during the parts welding process. The auxiliary devices are used to fix and position the parts during the welding process to ensure that the welded parts maintain the correct position and angle during welding, so as to improve the welding quality and efficiency.

[0003] For example, the Chinese patent application document with publication number CN117359083A, entitled "An adaptive hydraulic clamp for friction welding of curved surfaces", places the part above the mold when the part is larger than the capacity of the mold or is a curved part, and clamps the part between upper and lower relative positioning wheels. The positioning wheels move in the vertical direction on the positioning frame to self-adaptively clamp and fix the part, and the hydraulic distributor uses hydraulic pressure to control the auxiliary wheels to move upward so that the auxiliary wheels are against the part to adaptively support the part, and then the welding head is used to friction weld the part, so that the equipment can self-adapt to the shape of the part for clamping and fixing.

[0004] For the above related technologies, refer to Figure 1 The aluminum building material is composed of an arc-shaped bottom plate and a fan-shaped side plate. The arc-shaped bottom plate and the fan-shaped side plate are welded by a welding gun, and the side wall of the arc-shaped bottom plate is fixedly connected to a limit plate. The positioning wheel is difficult to limit the rotation of the arc-shaped bottom plate around its own central axis. Therefore, when the arc-shaped bottom plate rotates, the position of the arc-shaped bottom plate to be welded changes, and the position of the fan-shaped side plate needs to be readjusted, which increases the steps of the operator, reduces the welding efficiency of the aluminum building material, and reduces the welding accuracy between the arc-shaped bottom plate and the fan-shaped side plate.

DETAILED DESCRIPTION

[0039] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 10, the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0040] In the first aspect, this embodiment provides a high-efficiency aluminum building material welding device, referring to Figure 1 The aluminum building material 1 is composed of an arc-shaped bottom plate 11 and a fan-shaped side plate 12 . The arc-shaped bottom plate 11 and the fan-shaped side plate 12 are welded by a welding gun. The side wall of the arc-shaped bottom plate 11 is fixedly connected to a limiting plate 111 .

[0041] Reference Figure 2 , Figure 3 and Figure 4 A high-efficiency aluminum building material welding device includes a bracket 2, a support plate 3, a positioning plate 31, a first linear drive 4, a transmission block 41, a telescopic rod 42, a reset torsion spring 43, a positioning roller 44 and a reset spring 45. The bracket 2 is erected on a horizontal plane, the support plate 3 is fixed on the bracket 2, the upper surface of the support plate 3 is arc-shaped, and the upper surface of the support plate 3 can fit with the bottom surface of the arc-shaped bottom plate 11. The positioning plate 31 is fixedly connected to the upper surface of the support plate 3, and the side of the positioning plate 31 can abut against the side of the arc-shaped bottom plate 11, thereby limiting the arc-shaped bottom plate 11 in the axial direction.

[0042] Reference Figure 2 , Figure 3 and Figure 4 The first linear actuator 4 is arranged on the bracket 2, and the first linear actuator 4 is arranged above the support plate 3. The driving shaft of the first linear actuator 4 is fixedly connected to the transmission block 41. Four telescopic rods 42 are arranged, and the four telescopic rods 42 are evenly distributed on both sides of the transmission block 41 and are hinged to the transmission block 41. The two telescopic rods 42 located on the same side of the central axis of the support plate 3 are connected to a positioning roller 44 for common rotation. The positioning roller 44 is located at the end of the telescopic rod 42 away from the transmission block 41. The positioning roller 44 is parallel to the central axis of the support plate 3. The positioning roller 44 moves downward and can abut against the limit plate 111 on the arc bottom plate 11. The reset torsion spring 43 is fixedly connected between the transmission block 41 and the telescopic rod 42. The reset spring 45 is located between the transmission block 41 and the positioning roller 44. The reset spring 45 is sleeved on the telescopic rod 42 to push the telescopic rod 42 to extend.

[0043] First, place the arc bottom plate 11 on the upper surface of the support plate 3, and move the arc bottom plate 11 along the axial direction of the support plate 3 so that the arc bottom plate 11 abuts against the positioning plate 31. At this time, the side of the arc bottom plate 11 away from the positioning plate 31 protrudes from the side of the support plate 3, which is convenient for the arc bottom plate 11 to be welded. The first linear actuator 4 drives the positioning roller 44 to move downward through the transmission block 41 and the telescopic rod 42, so that the positioning roller 44 abuts against the upper surface of the arc bottom plate 11. The first linear actuator 4 continues to move the positioning roller 44 downward, and the positioning roller 44 rolls along the arc surface of the arc bottom plate 11 and abuts against the limit plate 111. The reset torsion spring 43 controls the angle between the telescopic rod 42 and the transmission block 41, so that the angles between the telescopic rods 42 on both sides of the transmission block 41 and the transmission block 41 are equal, thereby completing the positioning and fastening of the arc bottom plate 11. Then the operator places the fan-shaped side plate 12 on the arc-shaped bottom plate 11 , and then uses a welding gun to weld the contact position between the fan-shaped side plate 12 and the arc-shaped bottom plate 11 , thereby completing the welding work of the aluminum building material 1 .

[0044] The arc-shaped bottom plate 11 abuts against the support plate 3, and the positioning roller 44 abuts against the limit plate 111. The driving shaft of the first linear actuator 4 needs to continue to move downward to apply a tightening force to the arc-shaped bottom plate 11. At this time, the telescopic rod 42 is shortened, and the return spring 45 is compressed to buffer the squeezing force applied by the positioning roller 44 on the limit plate 111. Therefore, while the arc-shaped bottom plate 11 is pressed, the probability of the limit plate 111 being bent and deformed due to excessive force is reduced.

[0045] The first linear drive 4 enables the positioning roller 44 to move downward to press the arc bottom plate 11 while adjusting the position of the arc bottom plate 11 so that the distances between the two side surfaces of the arc bottom plate 11 and the central axis of the support plate 3 are equal, thereby improving the positioning accuracy of the arc bottom plate 11 and facilitating the alignment of the fan-shaped side panel 12 with the position where the arc bottom plate 11 needs to be welded, thereby replacing manual adjustment of the position of the fan-shaped side panel 12, thereby improving the welding efficiency of the aluminum building material 1 and improving the welding effect of the fan-shaped side panel 12 and the arc bottom plate 11.

[0046] Reference Figure 2 and Figure 5 The support plate 3 is provided with a second slide groove 32, in which a support rod 33 is slidably connected, and the support rod 33 is rotatably connected with a support ball 34 that can abut against the arc-shaped bottom plate 11 at one end away from the support plate 3, and a support spring 35 is provided in the second slide groove 32 for moving the support ball 34 out of the second slide groove 32.

[0047] When the operator places the arc bottom plate 11 on the support plate 3, the arc bottom plate 11 abuts against the support ball 34, and the support spring 35 supports the arc bottom plate 11 through the support ball 34. At this time, the bottom surface of the arc bottom plate 11 does not abut against the upper surface of the support plate 3. Therefore, when the positioning roller 44 adjusts the position of the arc bottom plate 11, the rotation of the support ball 34 can reduce the friction between the arc bottom plate 11 and the support plate 3, and the driving shaft of the first linear actuator 4 pushes the positioning roller 44 to continue to move downward, and the positioning roller 44 pushes the arc bottom plate 11 downward, so that the arc bottom plate 11 abuts against the support plate 3, and then the arc bottom plate 11 is tightened.

[0048] Reference Figure 3 and Figure 6 The positioning plate 31 is slidably connected to the support plate 3. The support plate 3 is provided with a plurality of locking holes 36 along the length direction. The outer side of the positioning plate 31 is provided with a locking mechanism 5. The locking mechanism 5 is used to fix the positioning plate 31 at different positions of the support plate 3 through the locking holes 36.

[0049] Reference Figure 3 and Figure 6 The locking mechanism 5 includes a supporting shell 51, a supporting ring 52, a locking rod 53, a locking spring 54 and a locking block 55. The supporting shell 51 is fixedly connected to the outer side of the positioning plate 31, and the supporting ring 52 is fixedly connected to the inside of the supporting shell 51. The side wall of the supporting ring 52 is axially provided with a first sliding groove 521 and a limiting groove 522, and the opening length of the first sliding groove 521 is greater than the opening length of the limiting groove 522. The locking rod 53 is slidably arranged inside the supporting ring 52, and the locking rod 53 can rotate in the supporting ring 52, and the locking rod 53 can move and extend into the locking hole 36. The locking spring 54 is arranged in the supporting shell 51, and is used to push the locking rod 53 to move. The locking block 55 is fixed on the arc surface of the locking rod 53, and the locking block 55 rotates around the central axis of the locking rod 53 and can alternately move into the first sliding groove 521 and the limiting groove 522. One end of the locking rod 53 away from the support plate 3 is fixedly connected with a pull ring 531. When the operator pulls the pull ring 531, the locking block 55 can be separated from the first sliding groove 521 and the limiting groove 522, and then the locking rod 53 is driven to rotate.

[0050] When the locking block 55 is located in the limiting groove 522, the locking rod 53 is located outside the locking hole 36, the locking spring 54 is compressed, and the operator can push the positioning plate 31 to move along the axial direction of the support plate 3. When the locking block 55 is located in the first slide groove 521, the locking spring 54 pushes the locking rod 53 to move into the locking hole 36, and the locking block 55 and the locking rod 53 move synchronously to abut against the bottom surface of the first slide groove 521. At this time, the locking rod 53 cooperates with the locking hole 36 to lock the positioning plate 31. In this way, the position of the positioning plate 31 relative to the support plate 3 can be adjusted according to the different lengths of the arc bottom plate 11, so that the support plate 3 can position the arc bottom plates 11 of different specifications.

[0051] Reference Figure 2 , Figure 7 and Figure 8 One end of the bracket 2 is fixedly connected to the second linear actuator 6, the driving shaft of the second linear actuator 6 is fixedly connected to the connecting plate 61, the connecting plate 61 is fixedly connected to the first sliding rod 62, the first sliding rod 62 is slidably connected to the adjusting plate 63, the adjusting plate 63 is vertically slidably connected to the bracket 2, the first sliding rod 62 is sleeved with a buffer spring 621, and the buffer spring 621 is arranged between the connecting plate 61 and the adjusting plate 63 to buffer the movement of the first sliding rod 62 relative to the adjusting plate 63. Adjustment rods 64 are horizontally slidably connected to both sides of the adjusting plate 63, the adjustment rods 64 are respectively abutted against the two side surfaces of the fan-shaped side plate 12, the outer side surface of the adjustment rod 64 is sleeved with an adjustment spring 641, and the bottom surface of the connecting plate 61 is fixedly connected to an extrusion block 65 that can abut against the upper surface of the fan-shaped side plate 12.

[0052] The operator places the fan-shaped side plate 12 between the adjustment rods 64 on both sides of the adjustment plate 63, and the adjustment spring 641 pushes the adjustment rod 64 to center the fan-shaped side plate 12. The adjustment spring 641 moves the fan-shaped side plate 12 to the middle of the arc bottom plate 11 through the adjustment rod 64. The driving shaft of the second linear actuator 6 drives the adjustment plate 63 to move downward through the connecting plate 61 and the first sliding rod 62, and the adjustment rod 64 moves synchronously with the connecting plate 61. The fan-shaped side plate 12 moves close to the arc bottom plate 11 due to its own gravity. At the same time, the second linear actuator 6 presses the fan-shaped side plate 12 downward through the connecting plate 61 and the extrusion block 65, and fastens the fan-shaped side plate 12 to the upper surface of the arc bottom plate 11. The first sliding rod 62 is slidably connected to the adjustment plate 63, and the first sliding rod 62 is fixedly connected to the extrusion block 65 through the connecting plate 61, so that the relative position of the extrusion block 65 and the adjustment plate 63 can be adjusted, so as to adapt to fan-shaped side plates 12 of different sizes.

[0053] The adjusting rod 64 moves the fan-shaped side panel 12 to the arc-shaped bottom plate 11 and adjusts the fan-shaped side panel 12 to the center at the same time, instead of manually adjusting the fan-shaped side panel 12. This is beneficial for aligning the arc-shaped bottom plate 11 with the fan-shaped side panel 12 at the welding position, improves the efficiency of welding the fan-shaped side panel 12 to the arc-shaped bottom plate 11, and improves the quality of the finished product after the arc-shaped bottom plate 11 and the fan-shaped side panel 12 are welded.

[0054] Reference Figure 7 and Fig.10The adjusting plate 63 is horizontally fixedly connected with a second slide bar 66, and the second slide bar 66 is slidably connected with a fastening plate 67 and a limiting rod 68. The fastening plate 67 is arranged between the adjusting plate 63 and the limiting rod 68, and the fan-shaped side plate 12 can vertically pass through between the adjusting plate 63 and the fastening plate 67. The second slide bar 66 is fixedly connected with a limiting block 662 at one end away from the adjusting plate 63, and the limiting block 662 is used to prevent the limiting rod 68 from being separated from the second slide bar 66. The outer side surface of the fastening plate 67 is fixedly connected with a first handle 671, and the upper surface of the limiting rod 68 is fixedly connected with a second handle 682. The fastening plate 67 is provided with a first friction inclined surface 672, and the limiting rod 68 is provided with a second friction inclined surface 681. The second slide bar 66 is sleeved with a tension spring 661, and the tension spring 661 is used to pull the limiting rod 68 to move through the second slide bar 66, so that the second friction inclined surface 681 abuts against the first friction inclined surface 672. When the second friction slope 681 abuts against the first friction slope 672 , due to the friction self-locking effect, the first friction slope 672 moves horizontally away from the adjustment plate 63 and cannot push the second friction slope 681 to move upward, thereby preventing the fastening plate 67 from moving away from the adjustment plate 63 .

[0055] The operator pulls the limit rod 68 upward through the second handle 682 to disengage the second friction slope 681 from the first friction slope 672. The operator pulls the fastening plate 67 away from the adjustment plate 63 through the first handle 671 to increase the distance between the adjustment plate 63 and the fastening plate 67. The operator then places the fan-shaped side panel 12 between the adjustment plate 63 and the fastening plate 67, and places the fan-shaped side panel 12 on the adjustment rod 64. The operator pushes the fastening plate 67 to the surface of the fan-shaped side plate 12 through the first handle 671, and the operator loosens the second handle 682 to make the first friction bevel 672 abut against the second friction bevel 681. The fastening plate 67 fixes the fan-shaped side plate 12 by utilizing the friction self-locking effect of the first friction bevel 672 and the second friction bevel 681 to prevent the fan-shaped side plate 12 from moving axially along the arc bottom plate 11. While preventing the fan-shaped side plate 12 from detaching from the adjusting rod 64, the positioning accuracy of the fan-shaped side plate 12 and the arc bottom plate 11 is improved.

[0056] Reference Figure 2 and Figure 7The bottom surface of the adjustment plate 63 is a first fastening surface 632, which is matched with the upper surface of the arc bottom plate 11 and can abut against the upper surface of the arc bottom plate 11. The lower bottom surface of the extrusion block 65 is a second fastening surface 651, which is matched with the upper surface of the fan-shaped side plate 12 and can abut against the upper surface of the fan-shaped side plate 12. In the vertical direction, the adjustment plate 63 can overlap with the support plate 3, and the extrusion block 65 does not overlap with the support plate 3, that is, the extrusion block 65 is located outside the support plate 3. Since when the arc-shaped bottom plate 11 abuts against the positioning plate 31, the side of the arc-shaped bottom plate 11 away from the positioning plate 31 protrudes from the side of the support plate 3, the first fastening surface 632 presses downward the arc-shaped bottom plate 11 just above the support plate 3, and the second fastening surface 651 presses downward the arc-shaped bottom plate 11 outside the support plate 3 through the fan-shaped side plate 12. The first fastening surface 632 fastens the arc-shaped bottom plate 11 between the positioning plate 31 and the second fastening surface 651, reducing the cantilever length of the arc-shaped bottom plate 11 relative to the positioning plate 31, thereby reducing the deformation of the arc-shaped bottom plate 11 caused by the second fastening surface 651 pressing the arc-shaped bottom plate 11 downward through the fan-shaped side plate 12.

[0057] Reference Figure 3 The end of the support plate 3 close to the adjustment plate 63 is higher than the end of the support plate 3 away from the adjustment plate 63, so that the arc bottom plate 11 moves downward by its own gravity and abuts against the positioning plate 31, which saves the operating steps of the operator and improves the welding efficiency of the aluminum building material 1. The bracket 2 is fixedly connected to the guide rod 21, and the central axis of the guide rod 21 is parallel to the axial direction of the support plate 3. The first linear drive 4 is slidably connected to the guide rod 21, and the positioning roller 44 moves synchronously with the first linear drive 4, thereby adjusting the position of the positioning roller 44 relative to the arc bottom plate 11 according to the synchronous length of the arc bottom plate 11.

[0058] The implementation principle of the high-efficiency aluminum building material welding device of the embodiment of the present invention is as follows: first, the arc bottom plate 11 is placed on the upper surface of the support plate 3, so that the arc bottom plate 11 abuts against the positioning plate 31, the positioning roller 44 moves downward to abut against the limit plate 111, and the reset torsion spring 43 controls the telescopic rod 42 to adjust the fan-shaped side plate 12 to the center. The operator pulls the limit rod 68 to move upward, and pulls the fastening plate 67 away from the adjustment plate 63, and then places the fan-shaped side plate 12 between the adjustment plate 63 and the fastening plate 67. The operator pushes the fastening plate 67 to the surface of the fan-shaped side plate 12 to fix the fan-shaped side plate 12. The operator places the fan-shaped side panel 12 on the adjusting rod 64, and the adjusting spring 641 pushes the adjusting rod 64 to center the fan-shaped side panel 12. The second linear actuator 6 fixes the fan-shaped side panel 12 on the upper surface of the arc-shaped bottom plate 11 through the connecting plate 61 and the extrusion block 65, and uses a welding gun to weld the arc-shaped bottom plate 11 and the fan-shaped side panel 12.

[0061] S2, the operator pulls the limit rod 68 to move upward, and pulls the fastening plate 67 to move away from the adjustment plate 63, and then places the fan-shaped side plate 12 between the adjustment plate 63 and the fastening plate 67. The operator pushes the fastening plate 67 to the surface of the fan-shaped side plate 12 to fix the fan-shaped side plate 12;

[0062] S3, the operator places the fan-shaped side panel 12 on the adjusting rod 64, and the adjusting spring 641 pushes the adjusting rod 64 to center the fan-shaped side panel 12.
