[0002] Welding is a commonly used method in machining to connect several independent profiles. When welding, without a reasonable tooling, the welding quality is extremely unstable, the profiles are difficult to position, and are prone to falling off, etc.

[0003] Currently, for products that weld four profiles into a complete frame, the conventional method only uses convex tenons for positioning at the four corners. The positioning is not comprehensive and cannot meet the dimensional requirements of the product's diagonal line, and it is very easy to deform the rectangular frame into a parallelogram; moreover, the processing cost of using convex tenons for positioning is high, and post-welding shaping treatment is required, which is time-consuming and laborious, resulting in an increase in the product cost.

Each clamping component includes a transverse clamping mechanism and a longitudinal clamping mechanism.

[0010] By adopting the above technical solution, the firmness of clamping can be ensured, and the force on each profile can be made more uniform, avoiding deformation due to excessive stress and ensuring the welding accuracy of the rectangular frame.

[0011] In an embodiment of the present utility model, the transverse clamping mechanism is a push cylinder, and the longitudinal clamping mechanism is a rotary cylinder.

[0012] In an embodiment of the present utility model, the platform is further provided with a fixing block for installing the push cylinder. The fixing block is provided with a through hole, and the output end of the push cylinder is located in the through hole.

[0013] In an embodiment of the present utility model, the platform is in a "cross" shape, and the platform between adjacent clamping assemblies has a notch.

[0014] By adopting the above technical solution, the four corners of the rectangular frame can be exposed. After the platform is flipped, welding can be performed on the reverse side of the rectangular frame from the notch position.

[0015] In an embodiment of the present utility model, the positioning block is in an "L" shape, and the positioning block is located at the four notches of the platform.

[0016] By adopting the above technical solution, one positioning block can respectively position one end of two profiles, and the four positioning blocks at the notch positions can realize the positioning of four profiles.

[0017] In an embodiment of the present utility model, the base is in a "U" shape structure. Bearing seats are provided on both sides of the base, and the platform is rotatably installed in the bearing seats of the base through the rotating shafts on both sides.

[0018] In an embodiment of the present utility model, a limit assembly for locking the rotation angle is further provided on the rotating shaft; the limit assembly includes a limit plate and a plunger. The limit plate is arranged on the rotating shaft and is located on one side of the bearing seat, and the plunger is installed on the limit plate to limit the rotation of the limit plate.

[0019] By adopting the above technical solution, the platform can be flipped to perform welding operations on the reverse side of the rectangular frame, and the plunger can lock the rotating shaft after flipping in place to realize the fixation of the platform.

[0026] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0027] Please refer to Figures 1-3 , the present utility model provides a quick positioning and flipping device for welded parts, including a base 1 and a platform 2. The platform 2 is rotatably arranged on the base 1. Four groups of clamping components 3 are arranged on the platform 2 in a "cross" shape. The clamping component 3 includes a transverse clamping mechanism 31 and a longitudinal clamping mechanism 32. A positioning block 4 that cooperates with the transverse clamping mechanism 31 to clamp the profile 8 from the side is arranged on the platform 2 and inside the transverse clamping mechanism 31, and the longitudinal clamping mechanism 32 clamps from above the profile 8.

[0028] The utility model quickly positions four profiles 8 through four groups of clamping assemblies 3 distributed in a "cross" shape, ensuring that the four profiles 8 form a rectangular frame rather than a parallelogram, thereby guaranteeing the welding precision of the product. In addition, each group of clamping assemblies 3 simultaneously fixes and clamps the profile 8 from both the side and the top, ensuring the clamping stability and reliability of each profile 8, and thus guaranteeing the welding dimensional precision of the rectangular frame.

[0029] Furthermore, two groups of clamping assemblies 3 at relative positions are symmetrically arranged. By arranging the clamping assemblies 3 in pairs symmetrically, it can be ensured that the forces on the two opposite profiles 8 are the same, reducing the deformation of the profiles 8 caused by uneven stress and guaranteeing the rectangular shape of the product.

[0030] Furthermore, each group of clamping assemblies 3 includes two transverse clamping mechanisms 31 and two longitudinal clamping mechanisms 32. By arranging two transverse clamping mechanisms 31 and two longitudinal clamping mechanisms 32 in each group of clamping assemblies 3, not only can the clamping firmness be ensured, but also the force on each profile 8 can be made more uniform, avoiding deformation due to excessive stress and guaranteeing the welding precision of the rectangular frame.

[0031] Specifically, the transverse clamping mechanism 31 is a push cylinder, and the longitudinal clamping mechanism 32 is a rotary cylinder.

[0032] Even further, a fixing block 5 is also provided on the platform 2 for installing the push cylinder. A through hole is provided on the fixing block 5, and the output end of the push cylinder is located in the through hole.

[0033] Furthermore, the platform 2 is in a "cross" shape, that is, there are notches 21 on the platform 2 between adjacent clamping assemblies 3. Through the notches 21 on the platform 2, the four corners of the rectangular frame can be exposed. After turning the platform 2 over, the reverse side of the rectangular frame can be welded from the position of the notches 21.

[0034] Furthermore, the positioning block 4 is in an "L" shape, and the positioning block 4 is located at the four notches 21 of the platform 2. Through the "L"-shaped positioning block 4, one positioning block 4 can respectively position one end of two profiles 8, and the four positioning blocks 4 at the notches 21 can realize the positioning of the four profiles 8.

[0035] Furthermore, the base 1 is in a "U" shape structure, and bearing seats 11 are provided on both sides of the base 1. The platform 2 is rotatably installed in the bearing seats 11 of the base 1 through the rotating shafts 6 on both sides.

[0036] Even further, a limit assembly 7 for locking the rotation angle is also provided on the rotating shaft 6; the limit assembly 7 includes a limit plate 71 and a plunger 72. The limit plate 71 is arranged on the rotating shaft 6 and located on one side of the bearing seat, and the plunger 72 is installed on the limit plate 71 to limit the rotation of the limit plate 71.

[0037] Further, a handwheel 61 is provided at one end of the rotating shaft 6 close to the limiting component 7. By providing the handwheel 61, it is convenient to rotate the platform 2, which is easy to operate and more labor-saving.

[0038] During use, first place two profiles 8 in the same direction on the platform 2 and position them through the positioning blocks 4, then the transverse clamping mechanism 31 clamps them from the side, and the longitudinal clamping mechanism 32 clamps them from above; similarly, place the other two profiles 8 in the other direction on the platform 2 for positioning and clamping; after the four profiles 8 form a rectangular frame, welding can be carried out. First, complete the flat welding on the front and vertical welding on the side of the rectangular frame; refer to Figure 3 , then pull out the plunger 72 and rotate the platform 2 by 180 degrees, and then limit it through the plunger 72 to weld the reverse side of the rectangular frame.

[0039] To sum up, the utility model quickly positions the four profiles through four groups of clamping components distributed in a "cross" shape, ensuring that the four profiles form a rectangular frame rather than a parallelogram, thus guaranteeing the welding accuracy of the product; in addition, each group of clamping components simultaneously fixes and clamps from the side and above of the profile, ensuring the clamping stability and reliability of each profile, thus guaranteeing the welding dimensional accuracy of the rectangular frame; the platform can rotate relative to the base, and the platform can be flipped 180 degrees to weld the back of the rectangular frame, making the welding more comprehensive. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0040] The above embodiments merely illustrate the principles and effects of the utility model, rather than limiting the utility model. All equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the utility model should still be covered by the claims of the utility model.
