[0008] As a preferred technical solution of this utility model, a magnetic switch is rotatably installed on the top of the movable magnetic base, and limit slide rods are fixedly connected to the front and rear sides of the movable magnetic base. An adjusting bolt is fixedly connected to the side of the movable magnetic base facing the front panel of the first positioning frame, and a first adjusting nut is threaded onto the adjusting bolt.

[0009] As a preferred embodiment of this utility model, the adjustment groove is also formed through the front and rear panels of the second positioning frame, and the front magnetic seat is also fixedly connected between the front and rear panels of the second positioning frame.

[0010] As a preferred technical solution of this utility model, the two sets of movable magnetic seats are slidably connected to the inner sides of the first positioning frame and the second positioning frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This auxiliary positioning mechanism for welding metal workpieces involves aligning the bottom of the first positioning frame with the welding surface of the workpiece, then unclamping the second positioning frame by turning the second adjusting nut in the opposite direction. While holding the first positioning frame in place, the second positioning frame is rotated under the constraints of the rotating shaft and threaded rod. During rotation, the position of the pointer on the rotating shaft is observed. Once the angle between the second and first positioning frames reaches the required welding angle, the second adjusting nut is rotated in the forward direction to re-clamp and fix the second positioning frame using the threaded rod. The workpiece to be welded is then placed on the upper surface of the second positioning frame and aligned with it. After alignment, it is slowly slid downwards until the workpiece contacts the bottom workpiece at a fixed angle. Finally, the first and second positioning frames and the workpiece are moved to adjust the final welding point, and the front magnetic seat is activated and the magnetic switch is turned to open the movable magnetic seat to fix the bottom workpiece and the workpiece to be welded. This device facilitates welding workpieces at a fixed angle.

[0016] This auxiliary positioning mechanism for welding metal workpieces releases the lock on the movable magnetic seat by unscrewing the first adjusting nut from the adjusting bolt. Then, under the limit of the limiting slide rod and the adjusting groove, the movable magnetic seat is moved to the left or right according to the size of the workpiece to adjust it. After the movable magnetic seat is adjusted, the first adjusting nut is screwed back into the adjusting bolt to lock the movable magnetic seat. Finally, the magnetic switch is rotated to fix the movable magnetic seat to the workpiece magnetically. This device is convenient for fixing welding workpieces of different sizes.

A support frame 102 is fixedly connected between the front and rear panels of the first positioning frame 1. A front magnetic seat 104 is fixedly connected between the front and rear panels of the first positioning frame 1. The adjustment slots 101 are also provided through the front and rear panels of the second positioning frame 103, and the front magnetic seat 104 is fixedly connected between the front and rear panels of the second positioning frame 103.

[0025] Please see Figure 5The adjustment mechanism 3 includes a first rotating hole 301, a second rotating hole 302, a scale line 303, a rotating shaft 304, a threaded rotating rod 305, and a second adjusting nut 306. The first rotating hole 301 is opened through the top of the front panel of the first positioning frame 1, and the second rotating hole 302 is opened through the top of the rear panel of the first positioning frame 1. The scale line 303 is fixedly connected to the outside of the front panel of the first positioning frame 1. The rotating shaft 304 is fixedly connected to the outside of the front panel of the second positioning frame 103. The threaded rotating rod 305 is fixedly connected to the outside of the rear panel of the second positioning frame 103. The second adjusting nut 306 is threadedly connected to the threaded rotating rod 305. The rotating shaft 304 is rotatably connected inside the first rotating hole 301. The outer end of the rotating shaft 304 is provided with a pointer, and the pointer at the outer end of the rotating shaft 304 is rotatably connected inside the scale line 303. The threaded rotating rod 305 is rotatably inserted into the inside of the second rotating hole 302. The inner side of the second adjusting nut 306 is in contact with the outer side of the rear panel of the first positioning frame 1.

[0026] By setting a first rotating hole 301, a second rotating hole 302, a rotating shaft 304, and a threaded rotating rod 305, the first positioning frame 1 and the second positioning frame 103 can be connected, and the function of adjusting the angle between the first positioning frame 1 and the second positioning frame 103 can be realized at the same time. By setting a second adjusting nut 306, the adjusted angle of the first positioning frame 1 and the second positioning frame 103 can be locked. A pointer is set at the outer end of the rotating shaft 304, and the pointer is rotatably connected in the scale line 303, so that the combined angle of the first positioning frame 1 and the second positioning frame 103 can be known by observing the position of the pointer pointing to the scale line 303.

[0027] Please see Figure 3-4 A magnetic switch 201 is rotatably mounted on the top of the movable magnetic base 2. Limiting slide rods 202 are fixedly connected to the front and rear sides of the movable magnetic base 2. An adjusting bolt 203 is fixedly connected to the side of the movable magnetic base 2 facing the front panel of the first positioning frame 1. A first adjusting nut 204 is threaded onto the adjusting bolt 203. The two sets of movable magnetic bases 2 are slidably connected to the inner sides of the first positioning frame 1 and the second positioning frame 103. The limiting slide rod 202 is slidably engaged inside the adjusting groove 101. The adjusting bolt 203 is slidably connected inside the adjusting groove 101.

[0028] By setting up a movable magnetic base 2, the workpiece can be fixed a second time. By setting up a limiting slide bar 202, an adjusting bolt 203 and a first adjusting nut 204, the position of the fixed movable magnetic base 2 can be adjusted, thereby fixing weldments of different sizes a second time.

[0029] Working principle: When a metal workpiece welding auxiliary positioning mechanism is used, in the initial state, the support frame 102 is first set inside the first positioning frame 1 and the second positioning frame 103 for support. A front magnetic seat 104 is also set inside the second positioning frame 103 and the first positioning frame 1 to facilitate magnetic fixing welding of the workpiece. The rotating shaft 304 and the threaded rotating rod 305, which are fixedly connected to the front and rear sides of the second positioning frame 103, are rotatably inserted into the first rotating hole 301 and the second rotating hole 302 opened at the front end of the first positioning frame 1. The second adjusting nut 306 connected to the threaded rotating rod 305 contacts the rear panel of the first positioning frame 1 to adjust and maintain the angle of the first positioning frame 1 and the second positioning frame 103. At the same time, the limiting slide rod 202 and the adjusting bolt 203 set on both sides of the movable magnetic seat 2 are slidably inserted into the inside of the adjusting groove 101. The first adjusting nut 204 is connected to the adjusting bolt 203 to fix workpieces of different sizes.

[0030] When welding a workpiece at a fixed angle is required, first align the bottom of the first positioning frame 1 with the welding surface of the workpiece. Then, untie the second adjusting nut 306 by turning it in the opposite direction to release the clamping and fixing of the second positioning frame 103. At this time, hold down the first positioning frame 1 and rotate the second positioning frame 103 under the limiting position of the rotating shaft 304 and the threaded rotating rod 305. During the rotation, observe the position of the pointer on the scale line 303 of the rotating shaft 304. Once the angle between the second positioning frame 103 and the first positioning frame 1 reaches the required welding angle, rotate the second adjusting nut 306 in the forward direction. The second positioning frame 103 is clamped and fixed again using the threaded rotating rod 305. At this time, the workpiece to be welded is placed on the upper surface of the second positioning frame 103 and attached to it. After attachment, it is slowly slid downward until the workpiece to be welded contacts the bottom workpiece at a fixed angle. Finally, the first positioning frame 1, the second positioning frame 103 and the workpiece to be welded are moved to adjust the final welding point position. The front magnetic seat 104 is turned on and the magnetic switch 201 is turned on to open the movable magnetic seat 2 to fix the bottom workpiece and the workpiece to be welded. This device facilitates welding of the workpiece at a fixed angle.
