[0019] Example 1

[0020] like Figures 1 to 3 As shown, the present invention proposes a rotary welding device, including a lifting platform 2, a horizontal displacement mechanism 3, a guide plate 405, a robotic arm mechanism 6, and an exhaust gas filtration mechanism 7. The lifting platform 2 is located on one side of the top of the base 1, and a three-jaw chuck mechanism 201 is rotatably connected to the lifting platform 2. The three-jaw chuck mechanism 201 is driven to rotate by a motor installed on the lifting platform 2. The horizontal displacement mechanism 3 is located on the other side of the top of the base 1, and a welding box is installed on the horizontal displacement mechanism 3. The welding box is provided with a glass observation window. The welding box is driven by the horizontal displacement mechanism 3 to move laterally along the base 1. Both sides of the welding box have clearance openings, which are connected to the three-jaw chuck mechanism. Corresponding to structure 201, the horizontal displacement mechanism 3 consists of a driving component and a support frame that is driven by the driving component to move laterally along the base 1. The top of the support frame is connected to the bottom of the welding box. The guide plate 405 is installed obliquely inside the welding box. A discharge channel is provided on the right side wall of the welding box and below the clearance opening. The discharge channel corresponds to the bottom of the guide plate 405 and a door is installed on the discharge channel. The robotic arm mechanism 6 is set at the top of the welding box. The output end of the robotic arm mechanism 6 extends into the welding box and is equipped with a welding torch 601. The exhaust gas filtration mechanism 7 is set at the top of the welding box. The intake end of the exhaust gas filtration mechanism 7 extends into the welding box and is located near the welding torch 601.

[0021] Furthermore, the exhaust gas treatment mechanism includes an exhaust gas filtration mechanism 7; the exhaust gas filtration mechanism 7 is located at the top of the welding cover 5, and the exhaust gas filtration mechanism 7 consists of a treatment box and a filter assembly located inside the treatment box. The filter assembly can be set as an activated carbon adsorption plate to filter welding odors and reduce pollution. The intake end of the exhaust gas filtration mechanism 7 is connected to a duct 701 through an air pump, and the absorption end of the duct 701 extends into the inside of the welding cover 5 and is equipped with multiple sets of suction hoods 702.

[0022] In this embodiment, the component to be welded by the hydraulic cylinder is clamped and fixed on the three-jaw chuck mechanism 201. The lifting platform 2 drives the hydraulic cylinder to move up and down to adjust it to a suitable position. The horizontal displacement mechanism 3 starts the welding box to move towards the hydraulic cylinder until the part to be welded on the hydraulic cylinder passes through the clearance port and is adjusted to a suitable position inside the welding box. The motor drives the three-jaw chuck mechanism 201 to rotate the hydraulic cylinder. The robotic arm mechanism 6 is existing technology and can drive the welding gun 601 to adjust to any angle to perform full welding on the hydraulic cylinder. The welding slag produced by welding slides along the guide plate 405 towards the discharge channel of the welding box. The welding slag can be disposed of by opening the door. The air pump is started to absorb the odor produced by welding gun 601 through multiple sets of air suction hoods 702 and enters the exhaust gas filter mechanism 7 through the duct 701 for filtration. After the odor is filtered out, it is discharged from the exhaust port of the exhaust gas filter mechanism 7, reducing air pollution. The welding box can cover the welding slag and welding odor, avoiding a large amount of welding slag splashing. At the same time, it facilitates the exhaust gas filter mechanism to absorb and filter the odor in time, reducing pollution.

[0023] Example 2

[0024] like Figures 1 to 4 As shown, the rotary welding device proposed in this utility model, compared with Embodiment 1, has a welding box consisting of a welding seat 4 and a welding cover 5 detachably installed on the top of the welding seat 4. The clearance opening on the welding box consists of two sets of arc-shaped openings 402, which are symmetrically arranged on the welding seat 4 and the welding cover 5. The guide plate 405 is installed on the inner wall of the welding seat 4, and the door is installed on the side wall of the welding seat 4. The exhaust gas treatment mechanism is installed on the welding cover 5.

[0025] Furthermore, the welding seat 4 is provided with a support mechanism, which includes a support plate 403 and a support roller 404. The support plate 403 is installed on the side wall of the welding seat 4 and is located above the guide plate 405. The support plate 403 is also provided with a set of arc-shaped openings 402. There are two sets of support rollers 404, which are rotatably connected between the support plate 403 and the side wall of the welding seat 4. The support rollers 404 are arranged laterally along the welding seat 4.

[0026] Furthermore, a disassembly and assembly mechanism is provided between the welding base 4 and the welding cover 5. The disassembly and assembly mechanism includes a positioning component and a locking component. The positioning component consists of a positioning rod 401 and a positioning hole 501. Multiple sets of positioning rods 401 and positioning holes 501 are evenly installed on the welding base 4 and the welding cover 5, respectively. The positioning rod 401 slides into the corresponding positioning hole 501. The locking component is provided between the welding base 4 and the welding cover 5 and is used to complete the disassembly and assembly of the welding base 4 and the welding cover 5.

[0027] Furthermore, the locking assembly includes a mounting plate 804, an L-shaped plate 8, and a sliding plate 802; the mounting plate 804 is mounted on the side wall of the welding seat 4, and a gear 801 is rotatably connected to the top of the mounting plate 804; one end of the L-shaped plate 8 is mounted on the side wall of the welding cover 5, and the other end of the L-shaped plate 8 slides vertically along the mounting plate 804; the sliding plate 802 slides vertically along the mounting plate 804, and toothed plates are mounted on both the sliding plate 802 and the L-shaped plate 8. The two sets of toothed plates are respectively engaged with the two side walls of the gear 801. The top of the L-shaped plate 8 has an opening that slides with the sliding plate 802. A sliding rod 803 is inserted into the upper end of the sliding plate 802, and the sliding rod 803 abuts against the top of the L-shaped plate 8.

[0028] In this embodiment, when the welding box moves toward the hydraulic cylinder and the welding part reaches above the support roller 404, the lifting platform 2 drives the hydraulic cylinder to adjust its vertical position so that the outer wall of the hydraulic cylinder contacts the outer peripheral surface of the two sets of support rollers 404. The two sets of support rollers 404 can rotate with the hydraulic cylinder. The support rollers 404 can support the hydraulic cylinder near the welding part, making the welding gun 601 welding more stable and improving the welding efficiency.

[0029] Lift the welding cover 5 so that the positioning hole 501 is aligned with the positioning rod 401 and inserted. Then, the insertion end of the L-shaped plate 8 slides down along the mounting plate 804 and is inserted. When the L-shaped plate 8 moves down along the mounting plate 804, the sliding plate 802 moves up along the through-hole on the mounting plate 804 until the insertion hole at the top of the sliding plate 802 is exposed. At the same time, the bottom end of the sliding rod 803 abuts against the top end of the L-shaped plate 8 and is inserted along the insertion hole on the sliding plate 802, thereby locking the sliding plate 802 and the L-shaped plate 8, and then locking the welding seat 4 and the welding cover 5. The assembly and disassembly are convenient and quick, and it is convenient to inspect the internal components of the welding seat 4 and the welding cover 5.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
