Description

Technical Field

[0001] This utility model relates to the field of furniture welding, and in particular to a rotary iron frame welding device. Background Technology

[0002] Furniture is an essential tool in people's daily lives. Commonly used furniture materials are mainly iron or steel, which are not easily damaged and have a long service life. In the production process of iron furniture, workers splice iron materials of different structures such as rods, plates and tubes to form an iron frame, and finally fix it by welding.

[0003] In existing iron frame welding processes, the iron frame is often placed on the ground or clamps for welding. To ensure the stability of the iron frame, welding is required at each joint. Traditionally, workers first spot weld the various connecting parts of the iron frame, and then perform full welding to achieve overall frame fixation. During the welding process, welding clamps are mostly of fixed size and cannot be adjusted, making it impossible to clamp iron frames of different sizes. Multiple clamps are often required for different iron frames, increasing operating costs. Furthermore, because the position of the welding clamps is relatively fixed, workers need to move back and forth to achieve overall welding; there is no way to achieve overall welding by rotating the workpiece, resulting in low welding efficiency and inconvenience. To address these problems, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide a rotary iron frame welding device to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A rotary iron frame welding device includes a support frame one and a connecting seat. The support frame one has a U-shaped structure. The connecting seat is rotatably mounted on the support frame one. A worm gear reducer motor is installed on the side wall of the support frame one. The output shaft of the worm gear reducer motor passes through the side wall of the support frame one and is fixedly connected to one end of the connecting seat. A square support frame two is installed on the top of the connecting seat. Adjustable frames are slidably arranged on both sides of the square support frame two. Both the square support frame two and the adjustable frames are hollow structures. The square support frame two has an adjustment component for adjusting the sliding of the adjustable frames. Both adjustable frames have multiple sets of clamping parts for clamping the iron frame.

[0007] Preferably, the adjustment assembly includes a double-ended screw, two sliders, and a support block. The support block is fixed inside the square support frame II. The middle part of the double-ended screw is rotatably mounted on the support block. The two sliders are threadedly engaged with both ends of the double-ended screw. The two sliders are respectively disposed inside the two adjustment frames and are fixedly connected to the inner wall of the adjustment frame. A connecting rod is installed at one end of the double-ended screw, and the end of the connecting rod away from the double-ended screw is disposed outside the adjustment frame. A rotating handwheel is installed on the connecting rod.

[0008] Preferably, the clamping part includes a support frame three, an L-shaped support plate, an adjusting screw, and a clamping plate. The support frame three is fixed to the side wall of the adjusting frame, the L-shaped support plate is fixed to the top of the support frame three, the adjusting screw is rotatably mounted on the L-shaped support plate, the adjusting screw is threadedly engaged with the L-shaped support plate, and the clamping plate is rotatably mounted at the bottom of the adjusting screw. The clamping plate and the adjusting screw are connected by a bearing.

[0009] Preferably, a rubber pad is fixed to the bottom of the clamping plate, and a rotating handle is installed on the top of the adjusting screw.

[0010] Preferably, the adjustment frame includes multiple support frames and multiple connecting frames, each support frame being disposed on one side of a connecting frame and fixed between two adjacent connecting frames. The square support frame includes multiple support frames and multiple connecting frames, each support frame being disposed on both sides of a connecting frame and fixed between two adjacent connecting frames. Each connecting frame corresponds to a connecting frame, and the connecting frame is slidably disposed within the connecting frame. The double-headed screw is disposed within one of the connecting frames and the connecting frame, and the support block is fixed inside the connecting frame.

[0011] Preferably, a baffle is fixed to the side of the adjustment frame away from the square support frame 2.

[0012] Beneficial effects: When welding is required on the iron frame, the extension distance of the adjusting frame can be adjusted first by adjusting the components. The two adjusting frames correspond to the size of the iron frame, and the adjustable settings of the adjusting frames can accommodate iron frames of different sizes, eliminating the need for multiple clamps and reducing usage costs. After the iron frame is installed, the clamping part is activated to clamp and fix both sides of the iron frame, allowing welding to proceed. After one side of the iron frame is welded, the worm gear reducer motor is activated, which drives the connecting seat to rotate. The connecting seat drives the square support frame and the adjusting frame to rotate, thereby rotating the iron frame and enabling welding at different angles. This eliminates the need for workers to walk back and forth during welding, improving welding efficiency and making welding more convenient. Attached Figure Description

Detailed Implementation

[0020] See Figures 1 to 6 As shown, a rotary iron frame welding device includes a support frame (1) and a connecting seat (2). The support frame (1) has a U-shaped structure. The connecting seat (2) is rotatably mounted on the support frame (1). A square support frame (4) is installed on the top of the connecting seat (2). Adjustment frames (5) are slidably arranged on both sides of the square support frame (4). Both the square support frame (4) and the adjustment frames (5) are hollow structures. An adjustment component (6) is provided inside the square support frame (4) for adjusting the sliding of the adjustment frame (5). When it is necessary to clamp the iron frame, the extension distance of the adjustment frame (5) can be changed by adjusting the adjustment component (6) to adapt the iron frame.

[0021] The adjusting assembly (6) includes a double-ended screw (61), two sliders (62), and a support block (63). The support block (63) is fixed inside the square support frame (4). The middle part of the double-ended screw (61) is rotatably mounted on the support block (63). The two sliders (62) are threadedly engaged with both ends of the double-ended screw (61). The two sliders (62) are respectively located inside the two adjusting frames (5), and the sliders (62) are fixedly connected to the inner wall of the adjusting frame (5). A connecting rod (64) is installed at one end of the double-ended screw (61). The end of the connecting rod (64) away from the double-ended screw (61) is located outside the adjusting frame (5). A rotating handwheel (65) is installed on the connecting rod (64). When adjusting the adjusting frame (5), first, rotate the rotating handwheel (65). The connecting rod (64) is rotated, which in turn drives the double-ended screw (61) to rotate. The double-ended screw (61) drives the slider (62) that is threaded to slide. During the sliding process, the slider (62) pushes the adjusting frame (5) to slide within the square support frame (4), thereby adjusting the extension distance of the adjusting frame (5). The adjusting frame (5) is first adjusted to a distance greater than the width of the iron frame. The iron frame is then placed on the two adjusting frames (5) and the square support frame (4). At this time, the adjusting frame (5) retracts. A baffle (53) is fixed on the side of the adjusting frame (5) away from the square support frame (4). The adjusting frame (5) moves until the baffle (53) contacts the iron frame. The baffles (53) on both sides limit the movement of the iron frame.

[0022] The adjustment frame (5) includes multiple support frames (51) and multiple connecting frames (52). Each support frame is located on one side of a connecting frame (52), and each support frame is fixed between two adjacent connecting frames (52). The square support frame (4) includes multiple support frames (41) and multiple connecting frames (42). Each support frame (41) is located on both sides of a connecting frame (42), and each support frame (41) is fixed between two adjacent connecting frames (42). Each connecting frame (52) corresponds to a connecting frame (42), and the connecting frames (52) are slidably set. Inside the second connecting frame (42), the double-headed screw (61) is set inside the first connecting frame (52) and the second connecting frame (42) on one side. The support block (63) is fixed inside the second connecting frame (42). The adjustment frame (5) is slidably set inside the second connecting frame (42) of the square support frame (4) through the first support frame (51), so as to realize the connection and cooperation between the adjustment frame (5) and the square support frame (4). When the double-headed screw (61) rotates, it pushes the first support frame (51) of the two sides of the adjustment frame (5) to slide through the slider (62), thereby realizing the distance adjustment.

[0023] Both adjustment frames (5) are provided with multiple clamping parts (7) for clamping the iron frame. After the iron frame is placed, the clamping parts (7) are used to press the iron frame, thereby fixing the iron frame and facilitating subsequent welding processing of the iron frame.

[0024] The clamping part (7) includes a support frame three, an L-shaped support plate (72), an adjusting screw (73), and a clamping plate (74). The support frame three is fixed to the side wall of the adjusting frame (5). The L-shaped support plate (72) is fixed to the top of the support frame three. The adjusting screw (73) is rotatably mounted on the L-shaped support plate (72). The adjusting screw (73) and the L-shaped support plate (72) are threaded together. The clamping plate (74) is rotatably mounted at the bottom of the adjusting screw (73). The clamping plate (74) and the adjusting screw (73) are connected by a bearing. After the iron frame is installed, the clamping plate (74) is located above the iron frame connecting rod (64). A rotating handle (76) is installed on the top. The adjusting screw (73) is rotated by rotating the handle (76). The adjusting screw (73) will drive the pressure plate (74) at the bottom to adjust the height. The pressure plate (74) and the adjusting screw (73) are connected by a bearing, so that the combined motion of rotation and sliding of the pressure plate (74) and the adjusting screw (73) becomes only sliding motion. The continuous downward pressure of the pressure plate (74) will make the pressure plate (74) contact the iron frame. A rubber pad (75) is fixed at the bottom of the pressure plate (74). The pressure plate (74) makes contact with the iron frame through the rubber pad (75), thereby achieving the pressing and fixing of the iron frame.

[0025] A worm gear reducer motor (3) is installed on the side wall of support frame one (1). The output shaft of the worm gear reducer motor (3) passes through the side wall of support frame one (1). The output shaft of the worm gear reducer motor (3) is fixedly connected to one end of the connecting seat (2). The two sides of the iron frame are clamped and fixed by the clamping part (7), so that welding can be performed. After one side of the iron frame is welded, the worm gear reducer motor (3) is started. The worm gear reducer motor (3) drives the connecting seat (2) to rotate. The connecting seat (2) drives the square support frame two (4) and the adjusting frame (5) to rotate, so that the iron frame can be rotated. Welding can be performed at different angles of the iron frame. There is no need for workers to walk back and forth to weld, which improves welding efficiency and makes welding more convenient.

[0026] Working principle: When welding is required on the iron frame, the extension distance of the adjustment frame (5) can be adjusted by adjusting component (6) so that the adjustment frame (5) can adapt to iron frames of different sizes. The adjustment frame (5) limits the iron frame by baffle (53). After the iron frame is placed, the clamping part (7) is activated. The clamping part (7) clamps and fixes the two sides of the iron frame by pressing plate (74), so that welding can be performed. After one side of the iron frame is welded, the worm gear reducer motor (3) is activated. The worm gear reducer motor (3) drives the connecting seat (2) to rotate. The connecting seat (2) drives the square support frame (4) and the adjustment frame (5) to rotate, so that the iron frame can be rotated, and welding can be performed on the iron frame at different angles.
