[0024] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] Please refer to Figure 1 and Figure 2, A positioning tool for profile welding, comprising a left plate 1 and a right plate 2. One end of the left plate 1 and the right plate 2 is rotatably connected. The left plate 1 and the right plate 2 are rotatably connected, and the included angle between the left plate 1 and the right plate 2 can be adjusted to facilitate the angular welding of profiles. When the left plate 1 and the right plate 2 are in the same horizontal plane, the two profiles are aligned for welding. Clamping components 3 are respectively rotatably connected to the upper ends of the left plate 1 and the right plate 2. Fixing components 4 are respectively provided at the upper ends of the left plate 1 and the right plate 2. One end of the clamping component 3 is rotatably connected to the left plate 1 and the right plate 2. The other end of the clamping component 3 is located in the through hole 6 and is clamped in the through hole 6 by the fixing component 4 to fix the clamping component 3 and prevent the clamping component 3 from rotating. The clamping component 3 positions and fixes the profiles, making the butt joints of the two profiles fit tightly to prevent the profiles from moving during welding. Angle adjusting components 5 are provided at the front ends of the left plate 1 and the right plate 2. Through holes 6 are respectively opened at the upper ends of the left plate 1 and the right plate 2. The through holes 6 are square funnel-shaped. The through holes 6 are used for one end of the clamping component 3 to enter and engage with the fixing component 4, thereby realizing the fixation of the clamping component 3. At the same time, the through holes 6 are set as funnel-shaped to facilitate the clamping component 3 to smoothly enter the through holes 6 and engage with the fixing component 4 for fixation. Counterbores 7 are respectively opened at the front ends of the left plate 1 and the right plate 2. The angle adjusting components 5 are inserted into the counterbores 7 and connected to the left plate 1 and the right plate 2. The angle adjusting components 5 are inserted into the counterbores 7 and connected to the left plate 1 and the right plate 2, making the left plate 1 and the right plate 2 stop rotating, thereby realizing the fixation of the included angle between the left plate 1 and the right plate 2. The distance from the counterbore 7 to the rotational connection of the left plate 1 and the right plate 2 is the same as the length of the angle adjusting component 5 when it is the shortest. Setting the distance from the counterbore 7 to the rotational connection of the left plate 1 and the right plate 2 to be the same as the length of the angle adjusting component 5 when it is the shortest enables the device to be applicable to the angles of profile welding from 60 degrees to 180 degrees.

[0026] Please refer to Figure 2The clamping assembly 3 includes a U-shaped frame 31 with an opening facing downward. The U-shaped frame 31 is set to a U-shape so that the U-shaped frame 31 can wrap the welding end of the profile to prevent the welding end of the longer profile from warping up due to the lever. The upper end of the U-shaped frame 31 is threadedly connected to a first threaded rod 32, and a downward pressure adjustment wheel 33 is fixed to the upper end of the first threaded rod 32. The lower end of the first threaded rod 32 is rotatably connected to a downward pressure block 34. The rear end of the U-shaped frame 31 is threadedly connected to a second threaded rod 35, and the front end of the second threaded rod 35 is rotatably connected to a clamping block 37. The rear end of the second threaded rod 35 is fixedly connected to a clamping adjustment wheel 36. Rotating the downward pressure adjustment wheel 33 and the clamping adjustment wheel 36 drives the corresponding first threaded rod 32 and second threaded rod 35 to rotate. At the same time, since the first threaded rod 32 and the second threaded rod 35 are threadedly connected to the U-shaped frame 31, the first threaded rod 32 and the second threaded rod 35 clamp and fix the profile against the lower pressing block 34 and the clamping block 37 to achieve the positioning of the profile. One end of the U-shaped frame 31 is rotatably connected to the corresponding left plate 1 or right plate 2, and the other end of the U-shaped frame 31 is provided with a fixing hole 38, and the lower end of the lower pressing block 34 is provided with an arc groove, and the front end of the clamping block 37 is provided with an arc groove. The two long rod-shaped profile welding ends are fixed by two clamping assemblies 3 to prevent the long rod profile from warping up at the welding end due to the principle of leverage, thereby increasing the probability of welding. By providing an arc groove at the lower end of the lower pressing block 34 and the front end of the clamping block 37, the clamping assembly 3 can also clamp and fix the circular profile, which is more applicable.

[0027] See also Figure 3 and Figure 4 The fixing assembly 4 includes a convex slide groove 41, and the front and rear ends of the slide groove 41 are symmetrically provided with limiting grooves 42. A slider 43 is slidably connected in the slide groove 41. The left end of the slider 43 is conical and the outer wall is provided with an inclined surface. The outer wall of the slider 43 is provided with a limiting block 44 corresponding to the limiting groove 42. The slider 43 slides in the slide groove 41, and the limiting block 44 slides in the limiting groove 42. Since the limiting groove 42 does not penetrate the slide groove 41, the limiting groove 42 and the limiting block 44 are slidably connected to the slider 43 to limit the slider 43, preventing the slider 43 from sliding out of the slide groove. 41, the left end of the slider 43 is conical and has an inclined surface. When the clamping component 3 enters the through hole 6, it directly contacts the inclined surface of the slider 43 to squeeze it, so that the slider 43 slides in the slide groove 41. When the fixing hole 38 on the clamping component 3 corresponds to the slider 43, the slider 43 slides out and is engaged in the fixing hole 38 to fix the clamping component 3. A paddle 45 is fixed to the upper end of the slider 43, and a clamping adjustment wheel 36 is placed in the slide groove 41. The spring 46 is a compression spring. The spring 46 cooperates with the slider 43 to achieve the effect of automatically clamping the clamping component 3.

[0028] Please refer to Figure 1 and Figure 2 wherein the angle adjusting assembly 5 includes an L-shaped adjusting rod 51 and a fixing post 52. One end of the adjusting rod 51 is inserted into the counterbore 7 of the left plate 1, and the other end of the adjusting rod 51 is threadedly connected to one end of a connecting cylinder 53. The other end of the connecting cylinder 53 is rotatably connected to one end of the fixing post 52, and the other end of the fixing post 52 is inserted into the counterbore 7 of the right plate 2. By rotatably connecting the left plate 1 and the right plate 2, welding of two profiles at a certain angle can be achieved. By connecting the left plate 1 and the right plate 2 through the angle adjusting assembly 5, the angle between the left plate 1 and the right plate 2 is limited to keep the angle unchanged, preventing the angle from changing during welding of the profiles. At the same time, by rotating the connecting cylinder 53, the length of the angle adjusting assembly 5 is adjusted, thereby adjusting the degree of the angle formed by the left plate 1 and the right plate 2.

[0029] When the present utility model is in use:

[0030] First, determine whether the profiles to be welded are welded in alignment or at a certain angle;

[0031] Then, when welding in alignment, place the welding ends of the profiles respectively below the clamping assemblies 3 at the upper ends of the left plate 1 and the right plate 2, rotate the clamping assemblies 3 so that the other ends of the clamping assemblies 3 enter the through holes 6, and fix the clamping assemblies 3 through the fixing assemblies 4;

[0032] When the profiles are welded at a certain angle, rotate the left plate 1 and the right plate 2 so that the angle between them corresponds to the welding angle of the profiles. Rotate the connecting cylinder 53 so that the adjusting rod 51 enters the connecting cylinder 53. After the angle adjusting assembly 5 is adjusted, insert both ends of the angle adjusting assembly 5 into the counterbores 7 of the left plate 1 and the right plate 2 to fix the angle between the left plate 1 and the right plate 2. After completion, place the welding ends of the profiles respectively below the clamping assemblies 3 at the upper ends of the left plate 1 and the right plate 2, rotate the clamping assemblies 3 so that the other ends of the clamping assemblies 3 enter the through holes 6, and fix the clamping assemblies 3 through the fixing assemblies 4;

[0033] Next, rotate the downward pressing adjusting wheel 33 and the clamping adjusting wheel 36 respectively to drive the corresponding first threaded rod 32 and second threaded rod 35 to rotate. At the same time, since the first threaded rod 32 and the second threaded rod 35 are threadedly connected to the U-shaped frame 31, the first threaded rod 32 and the second threaded rod 35 push against the downward pressing block 34 and the clamping block 37 to clamp and fix the profiles;

[0034] Finally, weld the two profiles through an existing welding device.

[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
