The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figure 1-6The utility model embodiment provides a flexible welding tool, which includes a base 1, the upper surface of the base 1 is fixedly connected to a support column 2, and a circular hole penetrating in the left and right horizontal directions is arranged near the upper surface of the support column 2, the cylindrical surface of the circular hole of the support column 2 is fixedly connected to a bearing 8, and the inner cylindrical surface of the bearing 8 is fixedly connected to a rotating shaft 4, and the rotating shaft 4 is fixedly connected to a frame 5 away from the support column 2. The frame 5 is on the right side of the support column 2, and a limiting mechanism 3 is arranged on the upper surface of the base 1 away from the support column 2. The number of the limiting mechanisms 3 is two and they are symmetrically distributed about the axis of the rotating shaft 4, and the frame 5 will not contact the legs 301 of the limiting mechanism 3 when rotating.

[0025] The inner surface of the frame 5 is provided with a mounting plate 6, and the mounting plate 6 is fixedly connected to a clamp 7. There are two clamps 7 distributed on adjacent mounting plates 6 perpendicular to each other, and the clamps 7 are fixed to the mounting plate 6 by screws.

[0026] The limiting mechanism 3 includes a leg 301, a sliding block 302, a spring 303, a sliding shaft 304, a pull ring 305, a limiting plate 306, a rotating plate 307, a fixed shaft 308, and a magnet 309. The leg 301 is fixedly connected to the upper surface of the base 1, and the leg 301 is on both sides of the front and rear side surfaces of the frame 5. The leg 301 is provided with a rectangular slide groove close to the frame 5, and the side surface of the leg 301 away from the frame 5 is provided with a circular slide groove that passes through the rectangular slide groove. The rectangular slide groove on the leg 301 can completely accommodate the sliding block 302 therein, and the sliding block 302 is slidably connected in the rectangular slide groove of the leg 301. The upper surface of the sliding block 302 contacts the lower surface of the frame 5, and the sliding shaft 304 is fixedly connected to the side surface of the sliding block 302 away from the frame 5, and the sliding shaft 304 passes through the circular slide groove of the leg 301.

[0027] The limit plate 306 is fixedly connected to the side surface of the leg 301 away from the frame 5. The limit plate 306 is directly above the pull ring 305. The side surface of the limit plate 306 away from the frame 5 is provided with a groove. The magnet 309 is fixedly connected in the groove of the limit plate 306. The thickness of the magnet 309 is the same as the depth of the groove of the limit plate 306. The fixed shaft 308 is fixedly connected to the side surface of the limit plate 306 away from the leg 301. The rotating plate 307 is rotatably connected to the cylindrical surface of the fixed shaft 308. The rotating plate 307 is made of iron. When the rotating plate 307 is rotated at normal times, it is adsorbed on the magnet 309. When it is separated from the adsorption force of the magnet 309 and droops under the influence of gravity and jams the pull ring 305, the sliding block 302 is completely pulled into the rectangular slide groove of the leg 301.

[0028] The spring 303 is fixedly connected between the side surface of the rectangular slide groove and the circular slide groove of the frame 5 and the side surface of the sliding block 302 close to the sliding shaft 304. The spring 303 is looped on the cylindrical surface of the sliding shaft 304. The pull ring 305 is fixedly connected to the side surface of the sliding shaft 304 away from the sliding block 302. When the elastic force of the spring 303 itself cannot push the sliding block 302, the upper surface of the sliding block 302 away from the spring 303 contacts the lower surface of the frame 5.

[0029] Working principle: After one side of the workpiece on the frame 5 is welded, the pull ring 305 is pulled to drive the sliding block 302 and the lower surface of the frame 5 to separate and completely retract into the rectangular slide groove of the leg 301, and then the rotating plate 307 is rotated downward to allow the rotating plate 307 to be stuck between the pull ring 305 and the leg 301, and then the hand pulling the pull ring 305 is released. At this time, the pull ring 305 is blocked by the rotating plate 307 and cannot return to the initial position, so the sliding block 302 will not rebound under the push of the spring 303. The same operation is performed on the other limiting mechanism 3. Then, the frame 5 is rotated half a circle, and then a rotating plate 307 is rotated upward. At this time, the pull ring 305 is unblocked, and the sliding block 302 will slide to below the lower surface of the frame 5 under the push of the spring 303, and then the lower surface of the frame 5 is brought into contact with the upper surface of the pop-up sliding block 302, and then the other rotating plate 307 is rotated upward, and the other sliding block 302 will slide directly to the bottom of the frame 5 and contact with its lower surface. At this time, the frame 5 is restricted by the two sliding blocks 302 and cannot continue to rotate, and at the same time, the workpiece on the frame 5 is also rotated half a circle.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
