Description

Technical Field

[0001] The present invention relates to the field of welding technology, and more particularly to an automatic correction structure for fine steel welding. Background Art

[0002] Fine steel is usually used in occasions with high precision requirements, such as precision machinery, high-end equipment manufacturing and other fields. During the welding process, even a tiny deviation may lead to a decline in the quality of the welded joint. The automatic correction structure can accurately adjust the welding position, ensure the alignment accuracy of the weld seam, and reduce welding defects such as undercut, incomplete penetration, porosity, etc. For example, in the welding of fine steel components in the aerospace field, automatic correction can make the strength and sealing performance of the welded joint meet strict standards, preventing potential safety hazards caused by welding quality problems;

[0003] Manually correcting the welding position is a time-consuming and cumbersome process, especially when dealing with fine steel components with complex shapes. The automatic correction structure can quickly identify and adjust the welding position, reducing the time for manual correction. For example, in the mass production of automotive parts, the automatic correction welding equipment can complete the welding of a large number of fine steel components in a short time, improving production efficiency and reducing production costs;

[0004] In the prior art, the welding of T-shaped steel structure plates is often to vertically splice two steel plates with the same size and then weld them.

However, due to the large mass of the steel plates, after welding, under their own weight, it is easy to cause the weld seam to bend, and there is a problem that the splicing angles of the two steel plates cannot correspond.

[0005] Therefore, an automatic correction structure for fine steel welding is proposed. Summary of the Invention

[0030] Please refer to Figures 1 to 6 , the present invention provides a technical solution:

[0031] An automatic correction structure for delicate steel welding, including a base 1. A vertical plate 2 is fixedly connected vertically to the rear side of the upper end surface of the base 1, and a top plate 4 is fixedly connected to the top of the vertical plate 2. A plurality of U-shaped gantries 8 are equidistantly distributed on the upper end surface of the base 1, and a positioning plate 7 is fixedly connected to the top of the gantry 8. The rear end of the positioning plate 7 is fixed to the vertical plate 2. A flipping and correcting mechanism 9 is rotatably connected inside the gantry 8. A fixing plate 3 is slidably connected to the rear side of the lower end surface of the top plate 4;

[0032] The flipping and correcting mechanism 9 is distributed in an annular structure, and positioning blocks 14 are provided between the upper side, left and right sides of the flipping and correcting mechanism 9 and the gantry 8. Positioning blocks 14 are also provided on the upper end surface of the base 1 and are rotatably connected to the flipping and correcting mechanism 9;

[0033] The flipping and correcting mechanism 9 includes a positioning ring 15 in an annular structure, and clamping members are annularly and equidistantly distributed inside the positioning ring 15. The clamping members include elastic clamping plates I 18 and elastic clamping plates II 19 with the same structural dimensions. Both the elastic clamping plates I 18 and the elastic clamping plates II 19 are fixed to the inner wall of the positioning ring 15, and electromagnets 20 are embedded in the adjacent surfaces of the elastic clamping plates I 18 and the elastic clamping plates II 19.

[0034] Specifically, a steel plate I 16 and a steel plate II 17 are distributed inside the positioning ring 15. Both ends of the steel plate I 16 are clamped and fixed inside two clamping members, and one end of the steel plate II 17 is clamped and fixed inside one clamping member. The steel plate I 16 and the steel plate II 17 are perpendicularly distributed.

[0035] Specifically, an output shaft 5 and a connecting rod 6 are distributed between the vertical plate 2 and the fixing plate 3. One end of the output shaft 5 is fixedly connected to an electric push rod 10, and one end of the electric push rod 10 is fixed to the vertical plate 2. The output shaft 5 and the connecting rod 6 are parallel to each other. The other end of the output shaft 5 is fixed to the fixing plate 3.

[0036] Specifically, a servo motor is fixed at the front end surface of the fixed plate 3 at a position corresponding to the connecting rod 6, the servo motor output shaft 5 is fixed to the connecting rod 6, and a movable groove 12 is provided through the surface of the vertical plate 2 at a position corresponding to the connecting rod 6, and the other end of the connecting rod 6 extends to the front side of the vertical plate 2 through the movable groove 12.

[0037] By adopting the above technical solution, the electric push rod 10 contracts to drive the output shaft 5 to move, and then drives the fixed plate 3 to slide on the top plate 4, thereby driving the connecting rod 6 to drive the welding head 11 to axially move, thereby achieving complete welding of the steel plate weld.

[0038] Specifically, welding heads 11 are distributed in an annular manner and at equal distances on the front end surface of the connecting rod 6, and the welding heads 11 are composed of a telescopic and adjustable structure.

[0039] By adopting the above technical solution, the rotating motor 13 is controlled to rotate forward and reversely, thereby driving the welding angle of the two steel plates to be further fine-tuned so that it matches the angle of the welding head 11.

[0040] Specifically, a rotating motor 13 is fixedly connected to the lower side of the positioning plate 7 , and the rotating motor 13 is transmission-connected to the front-side flipping correction mechanism 9 .

[0041] By adopting the above technical solution, the rotating motor 13 drives the gear 23 to rotate through the output end, and the gear 23 is meshed with the gear ring 24 to drive the positioning ring 15 in the positioning block 14 to rotate.

[0042] Specifically, the positioning block 14 is designed in a U-shaped structure and is wrapped around the positioning ring 15 . The positioning ring 15 has sliding grooves 22 on both sides thereof, and a slider 21 is slidably connected in the sliding groove 22 . The slider 21 is fixedly connected to the positioning block 14 .

[0043] By adopting the above technical solution, the slider 21 is slidably connected to the slide groove 22 , which can keep the positioning ring 15 stable in rotation in the positioning block 14 .

[0044] Specifically, a gear ring 24 is fixed to the outside of the positioning ring 15, a gear 23 is rotatably connected inside the positioning block 14, the gear 23 is meshed with the gear ring 24, the output shaft of the rotating motor 13 is fixedly connected to a transmission shaft 25, and the gear 23 is connected to the transmission shaft 25 fixed at the output end of the rotating motor 13.

[0045] By adopting the above technical solution, the rotating motor 13 then drives the transmission shaft 25 through the output end, drives the gear 23 to rotate through the transmission shaft 25, and drives the positioning ring 15 in the positioning block 14 to rotate through the engagement of the gear 23 with the gear ring 24.

[0046] Working principle: During operation, first place the two ends of steel plate 16 into the correspondingly distributed clamping members, which are connected to an external controller through electromagnets 20. Control the electromagnets 20 to conduct electricity and magnetically attract and pull elastic clamping plate 18 and elastic clamping plate 19 towards each other to firmly clamp and fix one end of the steel plate 16 between them. Subsequently, according to the welding handover between steel plate 17 and steel plate 16, insert one end of steel plate 17 into the clamping member at the corresponding position, and the other end of steel plate 17 contacts steel plate 16. The contact area between the two is the weld. The weld angle here is fixed and will not deform. For example, in this application, steel plate 16 and steel plate 17 are vertically distributed and are clamped and fixed by the clamping members. Subsequently, the controller controls the operation of the welding head 11 at a specified angle, and the length of the welding head 11 is adjustable to correspond to the weld. At this time, the user drives the connecting rod 6 to rotate through the servo motor, driving the welding head 11 to rotate to an angle corresponding to the weld. The visual sensor module is arranged on the lower end surface of the positioning plate 7 to accurately identify information such as the weld position and weld angle and feedback it to the controller. The controller timely adjusts the position of the welding head 11. Subsequently, the rotation motor 13 drives the transmission shaft 25 through the output end, drives the gear 23 to rotate through the transmission shaft 25, drives the positioning ring 15 in the positioning block 14 to rotate through the engagement of the gear 23 and the gear ring 24, and then drives the clamping members and the steel plate in the positioning ring 15 to rotate. By controlling the forward and reverse rotation of the rotation motor 13, the weld angle of the two steel plates is further finely adjusted to make it coincide with the angle of the welding head 11. Subsequently, the electric push rod 10 contracts, driving the displacement of the output shaft 5, and then driving the fixed plate 3 to slide and displace on the top plate 4, thereby driving the connecting rod 6 to drive the axial displacement of the welding head 11 to complete the welding of the steel plate weld. Generally, the welds are welded on both sides. After one side of the weld is welded, the welding head 11 is reset, and the rotation motor 13 drives the flipping and correcting mechanism 9 to rotate, driving the adjustment of the internal steel plate angle to process the welding of the other side of the weld.
