[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In one embodiment, such as Figures 1-5As shown, the robot large rotary workstation includes a workstation body 1. Inside the workstation body 1, there is a support base 4. A rotary base 3 is installed on the top of the support base 4. A second rotary frame 9 is installed on the top of the rotary base 3. A first servo motor is installed inside the rotary base 3. The output end of the first servo motor is fixedly connected to the second rotary frame 9. Two robot bodies 7 are symmetrically installed on the top of the second rotary frame 9. Each of the two robot bodies 7 is equipped with a welding torch 8. Two first rotary frames 6 are symmetrically fixedly connected to the outer wall of the second rotary frame 9. Two turntables 5 are symmetrically arranged on the end of each of the two first rotary frames 6 near the second rotary frame 9. Two second servo motors are symmetrically installed inside each of the two first rotary frames 6. The output ends of the two second servo motors are fixedly connected to the two turntables 5 respectively. The robot body 7 is equipped with a replacement mechanism for easy replacement of the welding torch 8.

[0036] In this embodiment, it should be noted that: a clamp for holding the workpiece is installed at the end of the turntable 5 away from the first rotary frame 6, and a wire feeding hose is provided at the top of the welding torch 8, and the welding torch 8 is threadedly connected to the wire feeding hose.

[0037] In use, the workpiece can be clamped and fixed at the end of the turntable 5 away from the first rotary frame 6 by the clamp. When the workpiece is clamped and fixed and there are no staff inside the main body of the workstation 1, the first servo motor is started to drive the second rotary frame 9 to rotate 180 degrees. At the same time, the two first rotary frames 6 are driven by the second rotary frame 9 to drive the turntable 5 to rotate synchronously, so as to quickly switch between the two turntables 5 with and without workpiece clamped.

[0038] Then, the two robot bodies 7 are started to drive the two welding guns 8 to weld the workpieces on the two turntables 5 respectively. At the same time, the two second servo motors are started to drive the two turntables 5 to rotate. This allows the angle of the workpiece to be automatically adjusted according to the welding requirements of the workpiece, so as to facilitate the welding of the workpiece. The above operation is repeated, so that the welded workpiece and the unwelded workpiece can be replaced while welding the workpiece, thereby further improving the welding efficiency of the workpiece.

[0039] When the welding torch 8 needs to be maintained or replaced, the welding torch 8 can be easily disassembled through the replacement mechanism. Then, the above operation is reversed to install and fix the new welding torch 8, thereby achieving the purpose of convenient replacement of the welding torch 8.

[0040] In one embodiment, such as Figures 2-5 As shown, the replacement mechanism includes: a support assembly mounted on the robot body 7;

[0041] The support component is a support frame 208 installed on one side of the robot body 7. The support frame 208 is slidably sleeved on the outer wall of the welding torch 8. The support frame 208 is L-shaped. An anti-slip rubber ring is fixedly connected to the bottom end of the support frame 208. The anti-slip rubber ring is in contact with the outer wall of the welding torch 8. The anti-slip rubber ring is used to limit the rotation of the welding torch 8, thereby preventing the welding torch 8 from rotating during the installation process.

[0042] A connecting component is provided on the support frame 208;

[0043] In one embodiment, such as Figures 2-5 As shown, the connecting component is a connecting cylinder 205 located below the support frame 208. The connecting cylinder 205 is sleeved on the outer wall of the welding torch 8 and is threadedly connected to the welding torch 8.

[0044] The support frame 208 is equipped with a fixing component;

[0045] The fixing components include: multiple connecting slide rods 206 that are circumferentially and equidistantly fixed to the bottom end of the support frame 208, and the multiple connecting slide rods 206 all penetrate into the interior of the connecting cylinder 205;

[0046] A positioning component is provided on the connecting slide bar 206;

[0047] The positioning component is a limiting slider 207 fixedly connected to the bottom end of the connecting slide bar 206, and the limiting slider 207 is located inside the connecting cylinder 205;

[0048] A sliding component is provided on the connecting cylinder 205;

[0049] The sliding assembly includes: an arc-shaped groove 204 formed at the junction of the connecting cylinder 205, the connecting slide rod 206, and the limiting slider 207; a docking slot 202 for the limiting slider 207 to slide is formed at the end of the connecting cylinder 205 located away from the connecting slide rod 206; the inner cavity of the docking slot 202 is connected to the inner cavity of the arc-shaped groove 204; through the cooperation of the connecting assembly, the fixing assembly, the positioning assembly, and the sliding assembly, the welding torch 8 can be easily disassembled and assembled, which is conducive to the purpose of quickly replacing the welding torch 8;

[0050] A limit component is provided on the connecting cylinder 205;

[0051] In one embodiment, such as Figures 2-4 As shown, the limiting component is a fixing plate 203 fixedly connected to the outer wall of the connecting cylinder 205, and the fixing plate 203 is located on the outside of the support frame 208;

[0052] A locking assembly is provided on the fixing plate 203;

[0053] The locking component is a bolt 201 located at the end of the fixed plate 203 away from the connecting cylinder 205. The bolt 201 passes through the fixed plate 203 to the interior of the support frame 208. The bolt 201 is threadedly connected to the support frame 208. Through the cooperation of the limiting component and the locking component, the connecting cylinder 205 can be locked and fixed.

[0054] The above embodiments disclose a large rotary workstation for robots. In use, a worker places a workpiece on one side of the second rotary frame 9 at the end of the turntable 5 away from the first rotary frame 6, and clamps and fixes the workpiece. When the workpiece is clamped and fixed, and there are no workers inside the main body 1 of the workstation, the first servo motor is started to drive the second rotary frame 9 to rotate 180 degrees. At the same time, the two first rotary frames 6, driven by the second rotary frame 9, drive the turntable 5 to rotate synchronously, so as to quickly switch between the two turntables 5 with and without workpieces clamped.

[0055] Then, the two robot bodies 7 are started to drive the two welding guns 8 to weld the workpieces on the two turntables 5 respectively. At the same time, the two second servo motors are started to drive the two turntables 5 to rotate. In this way, the angle of the workpiece can be automatically adjusted according to the welding requirements of the workpiece, so as to facilitate the welding of the workpiece.

[0056] During this process, the staff places the workpiece on one end of the switched turntable 5 and clamps and fixes the workpiece. When the workpiece is welded, the first servo motor is started to drive the second rotary frame 9 to rotate and reset. This allows the first rotary frame 6 to switch the two turntables 5 again. Then, the two robot bodies 7 are started so that the two welding guns 8 can perform welding operations on the new workpiece. This allows the welded workpiece and the unwelded workpiece to be replaced at the same time as the workpiece is being welded, thereby further improving the welding efficiency of the workpiece.

[0057] When maintenance or replacement of the welding torch 8 is required, the bolt 201 is rotated using a tool to separate it from the support frame 208. Then, the connecting cylinder 205 is rotated, causing the fixing plate 203 to rotate. Simultaneously, the welding torch 8 rotates synchronously under the influence of the connecting cylinder 205 via a threaded connection. At this time, the arc-shaped slide 204 slides along the outer wall of the connecting slide rod 206 and the limiting slider 207 under the influence of the connecting cylinder 205, until the limiting slider 207 contacts the inner wall of the mating slot 202. Then, the connecting cylinder 205 is pulled vertically downwards. At this time, the connecting cylinder 205 slides along the outer wall of the limiting slider 207 through the docking slot 202. At the same time, the welding gun 8 and the fixing plate 203 are moved synchronously under the drive of the connecting cylinder 205 until the welding gun 8 and the fixing plate 203 are separated from the support frame 208 under the drive of the connecting cylinder 205. Then, the connecting cylinder 205 is rotated to separate from the welding gun 8, so that the welding gun 8 can be easily disassembled. After that, the above operation is reversed to install and fix a new welding gun 8, so as to achieve the purpose of convenient replacement of the welding gun 8.

[0058] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
