Detailed Implementation

[0013] Example 1: See Figure 1 , Figure 2 and Figure 3 The present invention relates to an automatic TIG welding machine for joints, comprising a welding machine frame 1, a welding torch movable frame 2, a welding torch adjustment mechanism 3, a welding torch body 309, and a clamping mechanism 4.

[0015] Example 2: See Figure 4 , Figure 5 The welding torch adjustment mechanism 3 includes a fixed block 301, a fixed rod 302, a moving groove 303, a drive frame 304, a drive motor 305, a gear 306, a rack 307, and an adjustment frame 308. One side of the bottom of the welding torch movable frame 2 is fixedly connected to one side of the fixed block 301. The fixed block 301 is fixedly connected to the fixed rod 302. A vertically arranged moving groove 303 is provided on the outer wall of the fixed rod 302. The moving groove 303 is open at both the upper and lower ends of the fixed rod 302. One side of the fixed rod 302 is fixedly connected to one side of the drive frame 304. The inner... The wall is fixedly connected to one side of the housing of the drive motor 305. The output end of the drive motor 305 is fixedly connected to one end of the gear 306 through a coupling. The other end of the gear 306 is rotatably connected to the inner wall of the drive frame 304 through a rotating shaft. The rack 307 passes through the moving groove 303 and is slidably connected to the fixed rod 302 through the moving groove 303. The gear 306 extends into the moving groove 303 and meshes with the rack 307. The bottom side of the rack 307 is rotatably connected to the top side of the adjusting frame 308 through a rotating shaft. The adjusting frame 308 is fixed to the welding torch body 309.

[0016] The drive motor 305 is started to drive the gear 306 to rotate, which in turn drives the rack 307 to move stably inside the moving groove 303. The movement of the rack 307 and the welding wire connected to one end of the welding gun body 309 are used to limit the movement, which in turn drives the adjustment frame 308 to rotate, thereby driving the welding gun body 309 to adjust the angle. This allows the welding gun body 309 to be adjusted to the optimal welding posture, resulting in minimal discoloration of the weld after welding.

[0017] Example 3: See Figure 6The clamping mechanism 4 includes a fixed frame 401, a first clamping block 402, a slide rail frame 403, a movable frame 404, a drag chain 405, a bearing seat 406, and a second clamping block 407. The welding machine frame 1 is fixedly connected to the fixed frame 401. The fixed frame 401 has a rotating disk driven by a motor inside, and the rotating disk is connected to the first clamping block 402.

[0018] The welding machine frame 1 is fixedly connected to one side of the slide rail frame 403, and the other side of the slide rail frame 403 is slidably connected to one side of the movable frame 404. The bottom of the movable frame 404 is fixedly connected to one end of the drag chain 405, and the other end of the drag chain 405 is fixedly connected to one side of the slide rail frame 403. One side of the movable frame 404 is fixedly connected to one end of the bearing seat 406, and the inner wall of the other end of the bearing seat 406 is rotatably connected to the outer wall of one end of the second clamping block 407 through a bearing.

[0019] The fixed frame 401 and the movable frame 404 cooperate to make it easy to fix the workpiece with the first clamping block 402 and the second clamping block 407; the first clamping block 402, which can be driven by the rotating disk, and the rotatable second clamping block 407 cooperate to make the workpiece able to be rotated and welded.

[0020] The working process of this utility model: In the operation of this automatic TIG welding machine for joints, the two parts of the joint-type workpiece to be welded are pre-tack welded together. First, one part of the workpiece is clamped by the first clamping block 402. The drag chain 405 is activated, causing the moving frame 404 to slide on one side of the slide rail frame 403. The sliding of the moving frame 404 causes the second clamping block 407 to move towards the first clamping block 402 until the second clamping block 407 can clamp the other part of the workpiece. Once the second clamping block 407 has clamped the other part of the workpiece, the welding torch body 309 is adjusted to a suitable position using the welding torch movable frame 2. Positioning, the drive motor 305 is started to drive the gear 306 to rotate, which in turn drives the rack 307 to move stably inside the moving groove 303. The movement of the rack 307 and the welding wire connected to one end of the welding gun body 309 are used for limiting, which in turn drives the adjusting frame 308 to rotate, thereby driving the welding gun body 309 to adjust the angle. After adjustment, the motor inside the fixed frame 401 drives the rotating disk to rotate, and the rotating disk drives the first clamping block 402 to rotate. The first clamping block 402 drives the workpiece and the second clamping block 407 to rotate together, and the welding gun body 309 welds the workpiece.

[0021] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
