Description

Technical Field

[0001] The invention belongs to the technical field of steel plate welding, and in particular relates to a positioning fixture for steel plate welding. Background Art

[0002] Steel plate welding is a common and important metal connection process, which is widely used in many fields such as construction, machinery manufacturing, and automobile industry.

[0003] When welding the U-shaped steel corrugated plate, the existing technology fixes the steel corrugated plate on the welding machine and then uses the welding gun to weld the steel corrugated plate. When welding the U-shaped steel corrugated plate, the U-shaped steel corrugated plate itself is relatively curved and cannot be directly fitted with the welding machine. At this time, the staff needs to apply pressure to the U-shaped steel corrugated plate and press the U-shaped steel corrugated plate to fix it on the welding machine before the U-shaped steel corrugated plate can be welded with the welding gun. This method requires the staff to always press the U-shaped steel corrugated plate during the welding process to ensure that the U-shaped steel corrugated plate does not move during the welding process. However, long-term pressing will cause fatigue of the arms and hands, affect the reaction speed and attention of the staff, increase safety hazards, and when other parts of the U-shaped steel corrugated plate need to be welded, the U-shaped steel corrugated plate needs to be manually converted to the corresponding position so that the welding gun can weld the U-shaped steel corrugated plate, which greatly reduces the work efficiency and reliability when welding the U-shaped steel corrugated plate.

[0020] Specifically, the distance between the first slide plate 72 and the second slide plate 79 can be adjusted according to the distance between the two ends of the U-shaped steel corrugated plate to be welded, so as to fix the U-shaped steel corrugated plate. The angle of the first support plate 75 and the second support plate 98 can be adjusted according to the angles at both ends of the U-shaped steel corrugated plate, so that the inclination angle of the first support plate 75 and the second support plate 98 matches the inclination angle of both sides of the U-shaped steel corrugated plate, so that the first clamping plate 714 and the second clamping plate 918 can be moved to the inside of the wave of the U-shaped steel corrugated plate to fix the U-shaped steel corrugated plate. At the same time, the angle between the two sides of the wave inside the U-shaped steel corrugated plate to be welded can be adjusted. The angle of the first clamping plate 714 and the second clamping plate 918 can be adjusted to facilitate fixing the U-shaped steel corrugated plate with different inclination angles on both sides and different inclination angles inside the wave, avoiding the workers from always pressing the U-shaped steel corrugated plate during the welding process, affecting the workers' reaction speed and attention, and increasing safety hazards. When it is necessary to weld other positions of the U-shaped steel corrugated plate, the position where the U-shaped steel corrugated plate needs to be welded can be rotated to one side of the worker, which is convenient for continuing to weld the U-shaped steel corrugated plate, thereby greatly improving the work efficiency and reliability when welding the U-shaped steel corrugated plate.

[0021] In the embodiment, the angle adjustment assembly 12 includes two adjustment plates 121 slidingly connected to the inner wall of the third groove 11, the bottom ends of the two adjustment plates 121 are rotatably connected to the fourteenth electric telescopic rod 122, and the bottom end side walls of the two fourteenth electric telescopic rods 122 are fixedly connected to the same support base 123.

[0022] Specifically, when it is necessary to weld the inside of the U-shaped steel corrugated plate, the U-shaped steel corrugated plate needs to be tilted to a certain angle as a whole so that the welding machine can operate. At this time, the fourteenth electric telescopic rod 122 in the direction of tilting is controlled to start, driving the corresponding adjusting plate 121 to move upward. Since the bottom plate 1 is connected to the other adjusting plate 121 through the third groove 11 at this time, as the adjusting plate 121 moves upward, this adjusting plate 121 will move inside the third groove 11. Similarly, the other adjusting plate 121 will move in the third groove 11, but the other fourteenth electric telescopic rod 122 is not extended. At this time, the bottom plate 1 will tilt as a whole, driving the U-shaped steel corrugated plate to tilt. After the U-shaped steel corrugated plate tilts to a certain angle, the fourteenth electric telescopic rod 122 is controlled to stop extending, so as to achieve the tilting of the U-shaped steel corrugated plate, which is convenient for continuing to weld the U-shaped steel corrugated plate.

[0023] The operating principle of the present invention is now described as follows: When the U-shaped steel corrugated plate needs to be welded, the staff first controls the first electric slide rail 71 to start, drives the two first slide plates 72 to move, makes the spacing between the two first slide plates 72 smaller than the spacing between the two ends of the U-shaped steel corrugated plate to be welded, then controls the second electric telescopic rod 73 to start, drives the first side plate 77 to move upward, at this time, because one end of the first support plate 75 is fixedly connected to the first round rod 74, at this time, when the first side plate 77 drives the first support plate 75 to move upward, the first support plate 75 will rotate around the first round rod 74 as the center, and the first side plate 77 will move in the fourth groove 76, by controlling the extension and contraction of the second electric telescopic rod 73 to adjust the inclination angle of the first support plate 75, the two first support plates The angle of the plate 75 matches the inclination angle of the side walls at both ends of the U-shaped steel corrugated plate to be welded, and then the second electric slide rail 78 is controlled to start, driving the second slide plate 79 to move, so that the spacing between the three second slide plates 79 matches the spacing of the wave depressions on the inner wall of the U-shaped steel corrugated plate, and then the second motor 715 is controlled to start, driving the first side rod 712 to rotate, so that the angle between the two fourth electric telescopic rods 713 in the first U-shaped plate 711 matches the angle between the two sides of the wave on the inner wall of the U-shaped steel corrugated plate, and then the staff will place the U-shaped steel corrugated plate on the outer wall of the rotating rod 4 so that the inner wall of the U-shaped steel corrugated plate covers the first slide plate 72, and then the third electric telescopic rod 710 with the angle adjustment completed is controlled to start, so that the first U-shaped plate 71 1 enters the wave inside the inner wall of the U-shaped steel wave plate, and then controls the fourth electric telescopic rod 713 with the angle adjustment completed to start, drive the first clamping plate 714 to move, and use the first clamping plate 714 to fix the wave inner wall of the U-shaped steel wave plate, and when the staff places the U-shaped steel wave plate on the rotating rod 4, controls the fifth electric telescopic rod 91 to start, drive the mounting plate 92 to move upward, so that the outer wall clamping assembly 9 does not block the placement of the U-shaped steel wave plate, and then controls the third electric slide rail 93 to start, drive the two third slide plates 94 to move, so that the connecting block 96 is close to the outer wall of the U-shaped steel wave plate, and then controls the seventh electric telescopic rod 99 to start, drive the second side plate 911 to move downward, because one end of the second support plate 98 is connected to the first One end of the second round rod 97 is fixedly connected, and as the second side plate 911 drives the second support plate 98 to move downward, the second side plate 911 will gradually move inside the fifth groove 910. At this time, the second support plate 98 will rotate with the second round rod 97 as the center, thereby adjusting the angle between the second support plate 98 and the eighth electric telescopic rod 914, so that the inclination angle of the eighth electric telescopic rod 914 matches the inclination angle of the outer wall of the U-shaped steel wave plate, and then the third motor 919 is controlled to start, driving the corresponding second side rod 916 to rotate, so that the angle between the two ninth electric telescopic rods 917 matches the angle between the inner walls of the two ends of the wave of the outer wall of the U-shaped steel wave plate, and then the sixth electric telescopic rod 95 is controlled to start, driving the ninth electric telescopic rod 917 to move downward.Make the ninth electric telescopic rod 917 and the outer wall of the U-shaped steel wave plate in the same plane, then control the eighth electric telescopic rod 914 to start, so that the second clamping plate 918 enters the wave of the outer wall of the U-shaped steel wave plate, then control the ninth electric telescopic rod 917 to start, drive the second clamping plate 918 to move, and use the second clamping plate 918 to fix the wave of the outer wall of the U-shaped steel wave plate to achieve the fixation of the outer wall of the U-shaped steel wave plate, then control the thirteenth electric telescopic rod 106 to extend, at this time, since one end and the telescopic end of the thirteenth electric telescopic rod 106 are both rotatably connected to the outer walls of the two twelfth electric telescopic rods 105, as the thirteenth electric telescopic rod 106 is extended, the two twelfth electric telescopic rods 105 will be fixed with the corresponding fixing rods 104 The third clamping plate 107 is used to fix the middle wave of the U-shaped steel wave plate, thereby fixing the inner wall, outer wall and middle part of the U-shaped steel wave plate, so that the subsequent staff can use the welding gun to weld the U-shaped steel wave plate. When welding is performed at other positions, the first electric telescopic rod 2 is controlled to start, driving the connecting plate 3 to move upward, so that the U-shaped steel wave plate moves upward, and then the first motor 5 is controlled to start, driving the rotating rod 4 to rotate, so that the U-shaped steel wave plate rotates, until the position where the U-shaped steel wave plate needs to be welded is rotated to the side of the staff, so as to facilitate the continued welding of the U-shaped steel wave plate, and the distance between the first slide plate 72 and the second slide plate 79 can be adjusted according to the distance between the two ends of the U-shaped steel wave plate to be welded, so as to fix the U-shaped steel wave plate, and the angle of the first support plate 75 and the second support plate 98 can be adjusted according to the angle of the two ends of the U-shaped steel wave plate, so that the inclination angle of the first support plate 75 and the second support plate 98 is consistent with the angle of the U-shaped steel wave plate. The inclination angles on both sides of the plate match each other, which makes it easy for the first clamping plate 714 and the second clamping plate 918 to move into the inside of the wave of the U-shaped steel corrugated plate to fix the U-shaped steel corrugated plate. At the same time, the angles of the first clamping plate 714 and the second clamping plate 918 can be adjusted according to the angle between the two sides of the wave inside the U-shaped steel corrugated plate to be welded, thereby facilitating the fixation of the U-shaped steel corrugated plate with different inclination angles on both sides and different inclination angles inside the wave, avoiding the staff from always pressing the U-shaped steel corrugated plate during the welding process, affecting the staff's reaction speed and attention, and increasing safety hazards. When it is necessary to weld other positions of the U-shaped steel corrugated plate, the position where the U-shaped steel corrugated plate needs to be welded can be rotated to one side of the staff.It is convenient to continue welding the U-shaped steel corrugated plate, which greatly improves the work efficiency and reliability when welding the U-shaped steel corrugated plate.
