Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to an adaptive control automated welding device. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flame, electric arc, laser, electron beam, friction and ultrasound.

[0003] Existing automated welding platforms mostly use clamping robotic arms to hold and fix the materials to be welded, and then weld them using a welding torch. This type of clamping robotic arm works well for welding simple two rods or plates. However, when welding steel frames composed of multiple rods, it is difficult to fix them by clamping due to the large number of rods. Currently, the common method is to disassemble the steel frame and weld the rods in pairs to complete the welding of the steel frame. This method of welding steel frames is inefficient and cannot meet the needs of rapid production. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: An adaptive control automated welding device, such as Figure 1 As shown, it includes a welding platform 1, and a plurality of support legs 2 are fixedly provided at the bottom of the welding platform 1. The bottom of the support legs 2 is threadedly connected to a leveling support 3.

[0018] The welding platform 1 is equipped with a detachable workpiece fixing platform 8, specifically, as follows: Figure 1 As shown, in order to achieve quick assembly and disassembly of the workpiece fixing platform 8 and the welding platform 1, two first slide rails 4 are fixedly arranged on the welding platform 1 with left and right intervals. A first slider 5 is slidably arranged on the first slide rail 4. A fastening screw 7 is threaded through the first slider 5 and connected to it. The fastening screw 7 is used to fix the first slider 5 on the first slide rail 4. A support frame 6 is fixedly arranged on the top of the first slider 5. The support frame 6 has a through hole on the left and right. Fixing rods 9 extending in the left and right direction are fixed on both sides of the rectangular frame of the workpiece fixing platform 8. The fixing rods 9 can be inserted into the holes of the support frame 6.

[0019] The workpiece fixing platform 8 includes a rectangular frame connected end to end. The top of the rectangular frame is covered with several support unit plates 11, spaced apart horizontally and with adjustable left and right positions. The adjustable left and right positions of the support unit plates 11 allow the workpiece fixing platform 8 to meet the support and fixing needs of steel frames of different sizes. Specifically, for example... Figure 2 and Figure 3 As shown, the tops of the front and rear crossbeams of the rectangular frame are both fixedly equipped with slide rods 10 extending in the left-right direction. The bottoms of both the front and rear ends of the support unit plate 11 are fixedly equipped with second sliders 12, which slide on the slide rods 10.

[0020] Furthermore, a positioning screw is threaded through the second slider 12 and connected to it. One end of the positioning screw abuts against the slider 10 to fix the position of the second slider 12.

[0021] The support unit plate 11 supports the welded outer frame 15 and multiple inner support rods 16. The support unit plate 11 has multiple adjustable first positioning members 13 and second positioning members 14. The first positioning members 13 are located on the outer side of the outer frame 15 and spaced apart circumferentially. Each inner support rod 16 has a second positioning member 14 on both its left and right sides. The first positioning members 13 are used to press and fix the outer frame 15 onto the support unit plate 11, and the second positioning members 14 are used to press and fix the inner support rods 16 onto the support unit plate 11.

[0022] Specifically, such as Figure 3 As shown, the first positioning component 13 includes a first fixing block 1301 that can be detachably mounted on the support unit plate 11. The first fixing block 1301 is provided with a first lead screw that is threadedly connected to it. A first pressure plate 1302 is fixedly mounted on the top of the first lead screw. The first pressure plate 1302 is used to press and fix the outer frame 15 onto the support unit plate 11.

[0023] The second positioning component 14 includes a second fixing block 1401 that can be detachably mounted on the support unit plate 11. The second fixing block 1401 is provided with a second lead screw that is threadedly connected to it. A second pressure plate 1402 is fixedly mounted on the top of the second lead screw. The second pressure plate 1402 is used to press and fix the inner support rod 16 onto the support unit plate 11.

[0024] In this embodiment, the position adjustment method of the first positioning member 13 and the second positioning member 14 is as follows: the support unit plate 11 is provided with a number of through screw holes, and the bottom of the first fixing block 1301 and the second fixing block 1401 are both fixed with screw rods. The screw rods can be inserted into any one of the screw holes and threadedly connected to the nut to fix the first fixing block 1301 and the second fixing block 1401 on the support unit plate 11.

[0025] To further reduce the weight and material usage of the support unit plate 11, save costs, and improve the ease of installation and position adjustment of the first positioning member 13 and the second positioning member 14, such as Figure 3 As shown, the support unit plate 11 has several through slots 1102 that are spaced apart front and back and open from top to bottom. Screw holes are distributed on the left and right sides of the through slots 1102. The through slots 1102 allow the arm to pass through so that the positions of the first positioning member 13 and the second positioning member 14 can be adjusted without removing the support unit plate 11.

[0026] A second slide rail 18 extending in a left-right direction is provided above the welding platform 1. Vertical rods 17 are fixedly installed at the bottom of both ends of the second slide rail 18, and the vertical rods 17 are fixedly mounted on the welding platform 1. A welding device capable of left-right translation is provided on the second slide rail 18, and the welding device is located behind the workpiece fixing platform 8. Specifically, the welding device includes a third slider 19 slidably mounted on the second slide rail 18.

[0029] Working principle: When in use, place the rectangular frame of the workpiece fixing platform 8 on the welding platform 1, and move the support frames 6 on the left and right sides of the welding platform 1 so that the fixing rod 9 is inserted into the insertion hole of the support frame 6. Then, by rotating the fastening screw 7 on the first slider 5, the position of the first slider 5 and the support frame 6 is fixed to fix the position of the rectangular frame.

[0030] The second slider 12 slides the support unit plate 11 onto the slide rod 10. The position of the support unit plate 11 is adjusted according to the position of the outer frame 15 and inner support rod 16 to be welded, and the position of the support unit plate 11 is fixed by the positioning screw on the second slider 12.

[0031] like Figure 1 As shown, the outer frame 15 and the inner support rod 16 are then placed on the support unit plate 11. Based on the positions of the outer frame 15 and the inner support rod 16, the first positioning piece 13 and the second positioning piece 14 are installed on the support unit plate 11 one by one. Then, the outer frame 15 is pressed and fixed on the support unit plate 11 by rotating the first pressure plate 1302, and the inner support rod 16 is pressed and fixed on the support unit plate 11 by rotating the second pressure plate 1402.

[0032] The controller controls the moving drive device 20 to move the welding robot arm 22 left and right, the controller controls the rotating platform 21 to rotate the welding robot arm 22, and the controller controls the welding robot arm 22 to perform bending and welding operations to complete the welding operation of the steel frame.
