Description

Technical Field

[0001] This utility model relates to the field of welding support technology, specifically an adjustable angle welding support device with a limiting block. Background Technology

[0002] In fields such as machinery manufacturing and steel structure processing, welding is one of the core processes. Welding support devices, as key equipment ensuring welding accuracy and efficiency, directly impact welding quality. Currently, welding support devices on the market generally suffer from the following technical pain points: Traditional welding support tables are mostly designed with a fixed angle, only able to support the workpiece horizontally or at a specific angle. When tilting the workpiece for welding (such as welding bevels or butt joints of irregular structures), the angle must be adjusted by placing shims or changing support fixtures. This operation is cumbersome, and the angle accuracy is difficult to control, easily leading to poor weld formation and reduced weld strength due to angle deviation. While some adjustable-angle support devices achieve angle adjustment through bolts, hinges, etc., the adjustment process requires repeated disassembly and calibration, resulting in low operational efficiency and a lack of intuitive angle reference markings, making it difficult to meet the requirements of high-precision welding operations. Therefore, new technical solutions are needed to address these issues. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0016] Please see Figures 1-4 As shown, an adjustable angle welding support device with limiting blocks includes a support base plate 1. Welding support mechanisms 2 are mounted on both the left and right sides of the upper end of the support base plate 1. The welding support mechanism 2 includes a movable seat 5 mounted on the support base plate 1. Limiting arc plates 6 are vertically mounted on both the left and right sides of the upper end of the movable seat 5. A welding support platform 11 is assembled between the two limiting arc plates 6. Adjusting plates 16 are mounted on both the left and right sides of the bottom end of the welding support platform 11. A rotating shaft 13 is mounted on the side wall of the adjusting plate 16. A rotating hole 9 is opened at the center of the side wall of one limiting arc plate 6. A bearing is installed at the center of the side wall of the other limiting arc plate 6. The rotating shaft 13 on one side is installed in the rotating hole 9. The rotating shaft 13 on the other side is installed in the bearing. The rotating shaft 13 on one side extends through the rotating hole 9 to the outside of the limiting arc plate 6 and is then fitted with a limiting component 8.

[0017] In the specific implementation process, the support base plate 1 serves as the basic load-bearing component of the entire welding support device. The welding support mechanisms 2 assembled on the left and right sides of the upper end of the support base plate 1 are symmetrically distributed, and the structure and size of the two welding support mechanisms 2 are completely identical, ensuring the balance of the workpiece support. The movable seat 5 is detachably assembled with the support base plate 1. Positioning holes are opened at the four corners of the bottom end of the movable seat 5, which can be temporarily fixed to the support base plate 1 by bolts. When it is necessary to adjust the distance between the two welding support mechanisms 2, the bolts can be loosened to move it. After adjustment, the bolts are tightened again to complete the fixation. The bottom end of the welding support table 11 is equipped with a rotating shaft 13 through the adjusting plate 16. The rotating shaft 13 enables the welding support table 11 to rotate between the two limiting arc plates 6.

[0018] In some technical solutions, the limiting component 8 includes a limiting plate 18 installed at the end of the rotating shaft 13, a limiting screw 19 installed at the end of the limiting plate 18, and a limiting nut 20 screwed onto the outside of the limiting screw 19.

[0019] In the specific implementation process, after the rotating shaft 13 rotates in the rotating hole 9, the swing angle of the welding support table 11 is adjusted, and the limiting component 8 is used for limiting and fixing. The limiting screw 19 and the limiting nut 20 at the end of the rotating shaft 13 are threaded together to fix it.

[0020] In some technical solutions, a limiting ring 17 is installed at the end of the limiting screw 19, and a limiting groove 3 is opened on the side wall of the limiting nut 20, with the limiting ring 17 being engaged in the limiting groove 3.

[0021] In the specific implementation process, after the welding support platform 11 is adjusted to the required angle, the limiting nut 20 is tightened clockwise so that the limiting nut 20 fits tightly against the outer wall of the limiting arc plate 6. The rotating shaft 13 is fixed by friction to prevent it from rotating during the welding process. After the limiting ring 17 is engaged in the limiting groove 3, it can prevent the limiting nut 20 from being displaced in the axial direction, ensuring that the limiting nut 20 always maintains a stable screw connection with the limiting screw 19, and avoiding the limiting nut 20 from falling off the limiting screw 19 due to long-term use.

[0022] In some technical solutions, the outer wall of the limiting nut 20 is provided with slots 21 evenly spaced along its axis, and the side wall of the limiting ring 17 is provided with a retaining plate 22, which is engaged in the slots 21.

[0023] In the specific implementation process, after the limit nut 20 is tightened, the limit ring 17 is rotated to make the clamping plate 22 engage in the corresponding clamping groove 21, which can further fix the limit nut 20 circumferentially and prevent the limit nut 20 from loosening due to vibration during the welding process. When it is necessary to adjust the angle, first rotate the limit ring 17 to make the clamping plate 22 disengage from the clamping groove 21, and then loosen the limit nut 20 counterclockwise to perform the angle adjustment operation. The operation is convenient and the positioning is reliable.

[0024] In some technical solutions, the sidewall of the limiting arc plate 6 is provided with scale lines 10 along its axis.

[0025] In practice, the angle indication of the scale line 10 corresponds to the position of the slot 21.

[0026] In some technical solutions, the top of the welding support platform 11 is evenly spaced from left to right with stops 14, and a clamping cavity 15 is provided between two adjacent stops 14.

[0027] In the specific implementation process, when placing the workpiece, it is clamped in the corresponding clamping cavity 15. The stops 14 on both sides provide lateral restraint for the workpiece, preventing it from shifting left or right during welding. For longer workpieces, they can be simultaneously clamped in the corresponding clamping cavities 15 on the welding support tables 11 of the two welding support mechanisms 2, achieving multi-point restraint of the workpiece and further improving the stability of workpiece positioning.

[0028] In some technical solutions, a slide rail 4 is provided at the upper center of the support base plate 1, and a slider 7 is installed at the bottom of the movable seat 5. The slider 7 is installed in the slide rail 4.

[0029] In the specific implementation process, the position of the welding support mechanism 2 on the support base plate 1 is adjusted by moving the slider 7 within the slide rail 4.

[0030] In some technical solutions, handles 12 are installed on both sides of the movable seat 5.

[0031] In the specific implementation process, the handle 12 facilitates the movement of the movable seat 5.

[0032] Working principle: First, push the movable seat 5 with handle 12 to make the slider 7 slide along the slide rail 4 of the support base plate 1, and adjust the distance between the two welding support mechanisms 2 to match the length of the workpiece. Place the workpiece into the clamping cavity 15 of the welding support table 10. The stop block 14 achieves lateral limitation. When adjusting the angle, loosen the limiting nut 20, rotate the welding support table 11, and the adjusting plate 16 drives the rotating shaft 13 to rotate in the rotating hole 9 and bearing of the limiting arc plate 6. After determining the angle with reference to the scale line 11, tighten the limiting nut 20. The limiting ring 17 is inserted into the limiting groove 3 to prevent the axial displacement of the limiting nut 20. Then rotate the limiting ring 17 to make the clamping plate 22 be inserted into the clamping groove 21 to prevent the nut from vibrating and loosening. The positioning is completed, and the welding operation can be carried out.
