[0007] Preferably, the sliding rod located on the right side of the first sliding sleeve is an L-shaped rod structure, and the sliding rod located on the left side of the first sliding sleeve is a round rod structure, and the motor is used to control the rotation of the rotating shaft and the clamping wheel.

[0008] Preferably, a judging mechanism is provided at the top of the clamping wheel, and the judging mechanism includes a first rotating block, the bottom of the first rotating block is rotatably connected to the top of the clamping wheel, an articulated rod is hinged on the outer wall of the first rotating block, a second rotating block is hinged on the other end of the articulated rod, the bottom of the second rotating block is fixedly connected to the top of the clamping wheel, and the articulated rod is used to perform a hinged rotation function on the clamping wheel.

[0011] Preferably, the surface of the dial is provided with scale grooves, and the scale grooves are used to judge the position distance of the rotating bar.

[0012] The present invention provides a sheet metal argon arc welding positioning tool, which has the following beneficial effects: 1. The present invention sets a positioning mechanism, and uses the elastic force of the spring to tightly fit the clamping wheel on the outer wall of the annular sheet metal part. The elastic force of each spring will tightly press the clamping wheel against the placement seat, thereby realizing automatic fitting and clamping of the placement seat. This avoids the problem that the clamp cannot adapt to the clamping of different types of sheet metal parts due to different radii of different annular sheet metal parts, resulting in unstable clamping of the sheet metal parts and affecting the welding effect. It also avoids the problem of deformation and scratches on the clamping surface of the sheet metal part due to the inappropriate clamping of the clamp.

[0013] 2. The present invention sets a positioning mechanism. Since the clamping wheel allows the placement seat to rotate, the placement seat can complete the rotational welding of the sheet metal by rotating the clamped sheet metal during welding, thereby facilitating the staff to move it for rotation to complete the annular welding work and realize efficient welding and clamping of the annular sheet metal.

[0014] 3. The present invention sets a movable mechanism. After the sheet metal is clamped and tightened, the motor is started. The motor controls the rotating shaft to drive the clamping wheel to rotate. When the clamping wheel rotates, it will drive the sheet metal in contact with it to rotate. Therefore, the rotation of the sheet metal can be adjusted manually, and the rotation of the clamping wheel can be controlled by starting the motor through the rotating shaft to realize the rotation control of the sheet metal in different working states and different situations, thereby ensuring the diversification of operations during sheet metal welding processing and reducing the inconvenience of welding operations.

[0015] 4. The present invention sets a judgment mechanism. Different arcs after fitting will form different inclination angles of the first rotating block and the hinged rod. By observing the positions of the connecting plate and the rotating bar on the dial after the hinged rotation, the rotation angle can be judged, and then the arc and radius of the clamped sheet metal part can be judged, which is conducive to the subsequent staff's understanding and targeted operation. 5. The present invention sets a judgment mechanism so that the two rotating bars will rotate on the dial in the same way. By observing whether the positions of the two rotating bars on the dial are axially symmetrical, it can be judged whether the angles of the two hinged rods are the same. If they are the same, it means that the sheet metal part is a relatively uniform perfect circle. If the angles of the hinged rods on the left and right sides are different, it means that the arc surface of the outer wall of the sheet metal part is composed of multiple arcs and is not a stable perfect circle. This makes it easier for the staff to further judge and take targeted measures. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] Example 1: Please refer to Figure 1-3 The present invention provides a technical solution: a sheet metal argon arc welding positioning tool, comprising a welding machine 1, a workbench 5 is fixedly connected to the inner wall of the welding machine 1, a placement seat 6 is fixedly connected to the top of the workbench 5, and a positioning mechanism 2 is arranged on the top of the placement seat 6; The positioning mechanism 2 comprises: The electric telescopic rod 201, the bottom of the electric telescopic rod 201 is fixedly connected to the surface of the placement seat 6, one end of the electric telescopic rod 201 is fixedly connected to a push plate 202, the push plate 202 is an arc-shaped plate structure, one side of the push plate 202 is fixedly connected to a telescopic rod 203, and the electric telescopic rod 201 is used to push the push plate 202 to move forward and backward; The clamping wheel 204, one end of the telescopic rod 203 is fixedly connected to a pad, one side of the pad is rotatably connected to the outer wall of the clamping wheel 204 through a dovetail groove, one side of the pad is fixedly connected to a spring 205, one end of the spring 205 is fixedly connected to one side of the push plate 202, and the clamping wheel 204 is used to clamp the annular sheet metal.

[0019] The clamping wheel 204 is a circular columnar structure, the spring 205 is used to press against the clamping wheel 204 after being compressed to play the role of pushing the clamping wheel 204, and the telescopic rod 203 is used to limit the moving direction of the clamping wheel 204; When in use, the annular cylindrical sheet metal part is placed on the placement seat 6, and then the electric telescopic rod 201 is started to extend and control the push plate 202 to push forward. When the push plate 202 is pushed, the telescopic rod 203 and the spring 205 are driven to push forward synchronously, and the clamping wheel 204 is pushed by the spring 205 to hold the sheet metal part. Then the electric telescopic rod 201 continues to extend and push the push plate 202. At this time, several clamping wheels 204 will continuously fit and hold against the surface of the annular sheet metal part, and the telescopic rod 203 behind the clamping wheel 204 plays a role in the linear motion of the clamping wheel 204. The clamping wheel 204 is tightly attached to the outer wall of the annular sheet metal part by the elastic force of the spring 205, and the elastic force of each spring 205 will tightly press the clamping wheel 204 against the placement seat 6, so as to realize the automatic fitting and clamping of the placement seat 6, thereby avoiding the problem that the clamp cannot adapt to the clamping of various sheet metal parts due to different radii of different annular sheet metal parts, and the sheet metal part clamping is unstable, which affects the welding effect, and also avoids the problem that the clamping surface of the sheet metal part is deformed and scratched due to the incompatibility of the clamp; After the placement seat 6 is stably clamped by the clamping wheel 204, since the clamping wheel 204 allows the placement seat 6 to rotate, the placement seat 6 can complete the rotation welding of the sheet metal part by rotating the clamped sheet metal part during welding. Moreover, since the clamping wheel 204 is vertical, when the clamping wheel 204 clamps the sheet metal part, the sheet metal part cannot move up and down, but can rotate left and right, so that it is convenient for the staff to move it to rotate and complete the annular welding work, thereby realizing the efficient welding and clamping work of the annular sheet metal part. Example 2: Please refer to Figure 1-7On the basis of the first embodiment, the present invention provides a technical solution: a movable mechanism 3 is arranged on the outer wall of the push plate 202, and the movable mechanism 3 includes a sliding rod 301, and the outer wall of the sliding rod 301 is slidably connected with a first sliding sleeve 302, and the inner wall of the first sliding sleeve 302 is slidably connected with another sliding rod 301, and one end of the other sliding rod 301 is fixedly connected with the first sliding sleeve 302, and the output end of the first sliding sleeve 302 is fixedly connected with a rotating shaft 304, and the output end of the rotating shaft 304 is fixedly connected with the top of the clamping wheel 204, and the first sliding sleeve 302 is used to make the left and right sliding rods 301 slide therein.

[0020] The sliding rod 301 located on the right side of the first sliding sleeve 302 is an L-shaped rod structure, and the sliding rod 301 located on the left side of the first sliding sleeve 302 is a round rod structure. The motor 303 is used to control the rotation shaft 304 and the clamping wheel 204 to rotate. After the sheet metal is clamped and tightened, the motor 303 is started, and the motor 303 controls the rotating shaft 304 to drive the clamping wheel 204 to rotate. When the clamping wheel 204 rotates, it drives the sheet metal in contact with it to rotate, so that the rotation of the sheet metal can be adjusted manually, and the rotation of the clamping wheel 204 can be controlled by starting the motor 303 through the rotating shaft 304 to achieve different working states and different control of the rotation of the sheet metal under different conditions, thereby ensuring the diversification of operations during the sheet metal welding process and reducing the inconvenience of welding operations; Example 3: Please refer to Figure 1-13 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a judging mechanism 4 is arranged at the top of the clamping wheel 204, and the judging mechanism 4 includes a first rotating block 401, and the bottom of the first rotating block 401 is rotatably connected to the top of the clamping wheel 204, and the outer wall of the first rotating block 401 is hinged with a hinged rod 402, and the other end of the hinged rod 402 is hinged with a second rotating block 404, and the bottom of the second rotating block 404 is fixedly connected to the top of the clamping wheel 204, and the hinged rod 402 is used to play a role of hinged rotation on the clamping wheel 204.

[0021] The first rotating block 401 is a circular columnar structure. The inner wall of the first rotating block 401 is rotatably connected to the outer wall of the rotating shaft 304 through a bearing. The outer wall of the hinged rod 402 is slidably connected to the second sliding sleeve 403. The inner wall of the second sliding sleeve 403 is slidably connected to another hinged rod 402. One end of the other hinged rod 402 is hinged to the outer wall of the second rotating block 404.

[0022] The judging mechanism 4 also includes a connecting plate 405, an outer wall of the connecting plate 405 is fixedly connected to the outer wall of the hinged rod 402, a rotating bar 406 is fixedly connected to one side of the connecting plate 405, the rotating bar 406, the connecting plate 405 and the outer wall of the dial 407 are slidably connected, and the rotating bar 406 is used to slide and rotate on the dial 407.

[0023] The surface of the scale plate 407 is provided with a scale groove 408, and the scale groove 408 is used to judge the position distance of the rotating bar 406; After each clamping wheel 204 is against the outer wall of the sheet metal, the clamping wheels 204 will form an arc arrangement along the outer wall of the annular sheet metal, and the hinged rods 402 at the top of the middle clamping wheel 204 and the left and right clamping wheels 204 will be hinged and rotated on the first rotating block 401 and the second rotating block 404. The different arcs after fitting will form different inclination angles of the first rotating block 401 and the hinged rod 402. By observing the positions of the connecting plate 405 and the rotating bar 406 on the dial 407 on the hinged rod 402 after the hinged rotation, the rotation angle can be determined, and then the arc and radius of the clamped sheet metal can be determined, which is conducive to the subsequent understanding and targeted operation of the staff; There are two hinged rods 402 on the left and right clamping wheels 204. When the two hinged rods 402 rotate, they will drive the connecting plate 405 and the rotating bar 406 fixed on the outer wall to move on the dial 407. Originally, the two connecting plates 405 and the rotating bar 406 are located on the same line. When each clamping wheel 204 presses against the outer wall of the annular sheet metal to form an arc arrangement, the two rotating bars 406 will also rotate on the dial 407. By observing whether the positions of the two rotating bars 406 on the dial 407 are axially symmetrical, it can be determined whether the angles of the two hinged rods 402 are the same at this time. If they are the same, it means that the sheet metal is a relatively uniform perfect circle. If the angles of the hinged rods 402 on the left and right sides are different, it means that the arc surface of the outer wall of the sheet metal is composed of multiple arcs and is not a stable perfect circle, which makes it easier for the staff to further judge it and take targeted measures.
