[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 (refer to) Figure 1-4 This is the first embodiment of the present invention, which provides an adjustable positioning fixture for welded pipe molds, including a main body 1 and a mold 2. The mold 2 is disposed on the upper side of the main body 1, and a positioning mechanism 3 is provided on the outer surface of the mold 2. There are four positioning mechanisms 3. The four positioning mechanisms 3 include anti-slip plate 31, positioning plate 32, connecting plate 33 and stroke component 34. The side of anti-slip plate 31 close to mold 2 is in contact with the outer surface of mold 2. The side of positioning plate 32 close to anti-slip plate 31 is fixedly connected to the outer surface of anti-slip plate 31. The side of connecting plate 33 close to positioning plate 32 is fixedly connected to the outer surface of positioning plate 32. The stroke component 34 is located on the lower surface of connecting plate 33. The upper surface of the main body 1 is provided with a limiting groove 4. There are four limiting grooves 4, and the inner wall of the four limiting grooves 4 is slidably connected to the outer surface of the connecting plate 33.

[0022] Specifically, the connecting plate 33 moves along the limiting groove 4, causing the positioning plate 32 and the anti-slip plate 31 to move synchronously, so that the clamping force is evenly distributed on the surface of the mold 2, which can achieve the effect of quick positioning of the mold 2. Compared with the traditional fixing method of bolts and clamps, this method is faster and more stable.

[0023] Furthermore, the mold 2 is placed between the positioning mechanisms 3. Then, the connecting plate 33 moves along the inner wall of the limiting groove 4 towards the mold 2. The connecting plate 33 drives the positioning plate 32, which in turn drives the anti-slip plate 31 on the surface to move together until the outer surface of the anti-slip plate 31 is tightly attached to the outer surface of the mold 2, thereby fixing the mold 2.

[0024] Example 2: In the second embodiment of this utility model, the stroke assembly 34 includes a stroke column 341, a stroke plate 342, and a stroke groove 343. The upper end face of the stroke column 341 is fixedly connected to the lower surface of the connecting plate 33. The stroke plate 342 is disposed on the outer surface of the stroke column 341. The stroke groove 343 is opened on the surface of the stroke plate 342. The inner wall of the stroke groove 343 is slidably connected to the outer surface of the stroke column 341. A transmission assembly 5 is provided on the lower side of the stroke plate 342. The transmission assembly 5 includes a support column 51, a gear 52, and a toothed plate 53. There are four support columns 51. The outer surfaces of the four support columns 51 are fixedly connected to the inner wall of the stroke plate 342. The lower end face of the support column 51 is rotatably connected to the inner wall of the main body 1 through a bearing. There are four gears 52. The inner walls of the four gears 52 are fixedly connected to the outer surfaces of the support columns 51. The outer surfaces of the toothed plate 53 and the outer surfaces of the gears 52 are in a meshing relationship. The inner wall of the main body 1 is provided with a sliding groove 6, and the inner wall of the sliding groove 6 is slidably connected to the lower surface of the toothed plate 53.

[0025] Specifically, the linear motion of the toothed plate 53 is converted into rotational motion by the gear 52, and then converted into linear motion of the connecting plate 33 by the stroke groove 343. This composite motion and the design of the stroke groove 343 improve positioning accuracy.

[0026] Furthermore, the toothed plate 53 moves to the right along the inner wall of the slide groove 6, and the toothed plate 53 meshes with the four gears 52, so that the gears 52 rotate around the support column 51 as the rotation center. The support column 51 transmits the rotational force to the stroke plate 342, so that the stroke plate 342 drives the stroke groove 343 on the surface to rotate. The inner wall of the stroke groove 343 presses the stroke column 341, so that the stroke column 341 slides along the inner wall of the stroke groove 343. The stroke column 341 then drives the connecting plate 33 to move closer to the mold 2.

[0027] Example 3: In the third embodiment of this utility model, a drive assembly 7 is provided on the inner wall of the toothed plate 53. The drive assembly 7 includes a threaded rod 71 and a servo motor 72. The outer surface of the threaded rod 71 is rotatably connected to the inner wall of the toothed plate 53 by a thread. The output end of the servo motor 72 is fixedly connected to the right end face of the threaded rod 71, and the right surface of the servo motor 72 is fixedly connected to the inner wall of the main body 1. The outer surface of the threaded rod 71 is provided with a fastener 8. There are two fasteners 8. The inner walls of the two fasteners 8 are rotatably connected to the outer surface of the threaded rod 71 through bearings. The lower surface of the fastener 8 is fixedly connected to the inner wall of the main body 1.

[0028] Specifically, through the design of the drive component 7, in which the threaded drive has a self-locking function, when the motor stops, the toothed plate 53 stabilizes at the current position due to the thread friction, thereby enhancing the stability of the mold 2 after positioning.

[0029] Furthermore, in order to make the toothed plate 53 move laterally, the servo motor 72 drives the threaded rod 71 to rotate, and the threaded rod 71 drives the toothed plate 53 to move along the inner wall of the slide groove 6 through the thread.

[0030] The mold 2 is placed between the positioning mechanisms 3. Then, the servo motor 72 drives the threaded rod 71 to rotate. The threaded rod 71 drives the toothed plate 53 to move to the right along the inner wall of the slide groove 6 through the thread. The toothed plate 53 meshes with the four gears 52, so that the gears 52 rotate around the support column 51 as the rotation center. The support column 51 transmits the rotational force to the stroke plate 342, so that the stroke plate 342 drives the stroke groove 343 on the surface to rotate. The inner wall of the stroke groove 343 presses the stroke column 341, so that the stroke column 341 slides along the inner wall of the stroke groove 343. The stroke column 341 drives the connecting plate 33 to move along the inner wall of the limiting groove 4 to one side of the mold 2. The connecting plate 33 drives the positioning plate 32, so that the positioning plate 32 drives the anti-slip plate 31 on the surface to move together until the outer surface of the anti-slip plate 31 is tightly attached to the outer surface of the mold 2, thereby fixing the mold 2.

[0031] In summary, the combination of positioning mechanism 3, limiting groove 4, transmission component 5, slide 6, drive component 7, and fixing component 8 solves the problem of the cumbersome positioning method involving multiple bolts and multiple clamps, which requires workers to use professional tools for installation and positioning. If the bolts are accidentally lost or loosened during positioning, the stability of the mold after positioning will be greatly reduced.
