Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment technology, specifically to a multi-angle plate welding device. Background Technology

[0002] The welding of sheet metal requires multiple angles, including vertical, horizontal, and specified angle welding. Current sheet metal welding methods involve creating various angle positioning fixtures for the welding operation. This method has drawbacks such as a large variety of fixtures, difficulties in fixing and welding after positioning, and inaccurate angles. Furthermore, the frequent change of fixtures for different welding requirements significantly reduces production efficiency. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this utility model proposes a multi-angle plate welding device, which can conveniently realize the angle adjustment and fixation of the plates to be welded, reduce the difficulty of angle adjustment, save production time, and improve production efficiency.

[0004] To achieve the above objectives, the multi-angle plate welding device of this utility model includes a main base, a manual lifting mechanism on one side of the main base, a roller base that can be raised and lowered along the manual lifting mechanism, a rotation positioning component on the side of the main base opposite to the manual lifting mechanism, the roller base and the rotation positioning component together support the inclined plate to be welded, and the main base is used to support the horizontal plate to be welded.

[0018] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0019] like Figure 1 As shown, the multi-angle plate welding device of the preferred embodiment of this utility model includes a main base 1, with support feet 11 at the four corners of the bottom of the main base 1. A manual lifting mechanism is provided on one side of the main base 1, and a roller base that can be raised and lowered along the manual lifting mechanism is provided on the manual lifting mechanism. A rotation positioning component is provided on the side of the main base 1 opposite to the manual lifting mechanism. The roller base and the rotation positioning component together support the inclined plate to be welded, and the main base 1 is used to support the horizontal plate to be welded.

[0020] like Figure 2 and Figure 3 As shown, the manual lifting mechanism includes a vertical support 21 arranged in a vertical direction. A first bearing seat 22 is provided at the top of the vertical support 21, and a second bearing seat 23 is provided at the bottom of the vertical support 21. A lead screw 24 is provided between the first bearing seat 22 and the second bearing seat 23. The two ends of the lead screw 24 are rotatably connected to the first bearing seat 22 and the second bearing seat 23, respectively. A manual turntable 26 is provided at the top of the lead screw 24 above the first bearing seat 22. By rotating the manual turntable 26, the lead screw 24 is rotated along its own axis. A lead screw nut 25 is provided on the lead screw 24. The lead screw nut 25 and the lead screw 24 form a lead screw pair. The rotation of the lead screw 24 drives the lead screw nut 25 to rise and fall along the lead screw 24.

[0021] like Figure 2 and Figure 3 As shown, a roller base is mounted on the lead screw nut 25, and the roller base includes a roller support plate 31 arranged horizontally. Two guide posts 41 are provided on the vertical support 21, each positioned on one side of the lead screw 24. Sliding blocks 42 are slidably connected to the guide posts 41 and are fixedly connected to the roller support plate 31. The guide posts 41 on both sides restrict the horizontal movement of the roller support plate 31, thereby limiting the rotation of the lead screw nut 25 and forcing it to rise and fall with the rotation of the lead screw 24 rather than rotating accordingly.

[0022] like Figure 2 and Figure 3 As shown, the top of the vertical support 21 is equipped with a quick-locking device 51 located above the first bearing seat 22. The top end of the lead screw 24 passes through the locking hole of the quick-locking device 51. After the quick clamp 52 of the quick-locking device 51 is clamped, it restricts the rotation of the lead screw 24. When the roller base is raised or lowered to a suitable height, the quick clamp 52 is clamped to maintain the stability of the roller base.

[0023] like Figure 2 and Figure 3As shown, the roller support plate 31 extends towards the side closest to the rotary positioning assembly. A sliding roller 32 is provided on the side of the roller support plate 31 away from the lead screw nut 25. The sliding roller 32 supports the inclined plate and reduces friction on the plate during the rising and falling of the roller base. The main base 1 has a U-shaped plate structure, and the roller support plate 31 can descend below the main base 1 through the U-shaped notch.

[0024] like Figure 2 and Figure 3 As shown, the rotary positioning assembly includes two rotating hinges 61 disposed on the side of the main base 1. Each rotating hinge 61 is a spring hinge, requiring a certain force to rotate; it cannot move without force. Driven by elasticity, the rotating hinges 61 tend to rotate towards the main base 1, thus cooperating with sliding and rolling to maintain the stability of the plate. A fixing plate 62 is provided on one side of the main base 1 near the rotary positioning assembly. An angle plate 63 is provided at the end of one side of the main base 1 opposite the fixing plate 62. When the plate abuts against the bottom of the rotating hinges 61 on both sides, the angle plate 63 can measure the angle between the inclined plate and the main base 1.

[0025] Specific implementation process: Before welding, first open the quick clamp 52 of the quick-locking device 51 to release the lock on the lead screw 24, then rotate the manual turntable 26 in the reverse direction to lower the roller support plate 31 below the main base 1. At this time, the overall state of the device is as follows: Figure 3 As shown. Then open the rotating hinges 61 on both sides and place the first plate on the surface of the main base 1. The end of the first plate should reach the bottom of the rotating hinge 61. Then rotate the manual turntable 26 to raise the roller support plate 31 and make a circular motion around one side. At this time, the first plate is raised on one side under the action of the roller support plate 31, while the other half remains in contact with the rotating hinge 61, so that the plate as a whole forms a certain angle with the main base 1. The angle is read by the angle plate 63. When the set angle is reached, stop rotating the manual turntable 26, clamp the quick clamp 52 of the quick locking device 51, and lock the screw 24. At this time, the overall state of the device is as shown. Figure 2 As shown. Then place the second board onto the main base 1, aligning the sides of the two boards, as shown. Figure 1 As shown, welding can begin immediately. Weld from the inner corner first, then from the outside. No hand support is required during the welding process. After welding is complete, repeat the operation of lowering the roller support plate 31 to easily remove the welded part.

[0026] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims.
