[0037] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0038] like Figure 1 As shown, a simple welding bracket includes a base 1, a support column 2, a support assembly 5 arranged above the base 1 and a clamping assembly arranged on the base 1, wherein the support assembly 5 is arranged below the clamping assembly; wherein the support assembly 5 is used to support a workpiece, and the clamping assembly is used to press downward the workpiece placed on the support assembly 5; the top of the support column 2 is laterally bent to form a first beam 21; a second beam 22 is also arranged below the first beam 21, and the end of the second beam 22 is welded and fixed to the support column 2; the clamping assembly is fixed to the ends of the first beam 21 and the second beam 22.

[0039] like Figure 1 As shown, a connecting plate is welded to the bottom of the support column 2, and the connecting plate is fixedly connected to the base 1 by bolts.

[0040] The utility model discloses a simplified welding bracket with a simple structure. When manufacturing the bracket, local materials can be used, and very conventional steel can be used for manufacturing. Not only is the manufacturing cost low, but the weight is also light and convenient to carry. The support column 2 of the application is provided with a first crossbeam 21 and a second crossbeam 22, which are not only used to increase the stability of the clamping assembly when in use, but the first crossbeam 21 can also be used as a handle to facilitate the carrying (hand-held) of the bracket.

[0041] like Figure 2 , Figure 3 As shown, the clamping assembly includes a threaded sleeve 3 welded to the ends of the first beam 21 and the second beam 22; the inner side of the threaded sleeve 3 has an internal thread, and a threaded rod 4 is correspondingly arranged inside the threaded sleeve 3. A fixed handle 41 is welded to the top of the threaded rod 4, and the threaded rod 4 is rotated by the handle 41. Figure 2 , Figure 3 As shown, the handle 41 can be made of a small round steel, which is welded to the top of the threaded rod 4 to form the handle 41. The threaded rod 4 is used to press the workpiece downward. When in use, the threaded rod 4 only needs to be rotated to move the threaded rod 4 downward to press the workpiece, which is convenient for welding the workpiece, and of course, it is also convenient to perform other operations on the workpiece, such as polishing, processing, etc.

[0042] In one embodiment, if Figure 2 , Figure 3 As shown, a clamping head 6 is also provided at the lower end of the threaded rod 4. The clamping head 6 includes a rotating sleeve 61, a clamping block 62 fixed to the lower end of the rotating sleeve 61, and a limiting rod 63 welded and fixed to both sides of the rotating sleeve 61; a light hole matching the outer diameter of the threaded rod 4 is provided on the inner side of the rotating sleeve 61; the upper end of the rotating sleeve 61 is rotatably connected to the threaded rod 4, and guide channel steels 7 are also welded on both sides of the threaded sleeve 3, and the outer end of the limiting rod 63 is arranged in the guide channel steel 7 ( Figure 3 The middle guide channel steel 7 is displayed in an exploded form to facilitate the display of the specific structure of the clamping head 6). The upper end of the rotating sleeve 61 is rotatably connected to the threaded rod 4, that is, it is rotatably arranged at the lower end of the threaded rod 4. When the threaded rod 4 is rotated, the threaded rod 4 will move downward or upward. Since the rotating sleeve 61 has a limit rod 63, the rotating sleeve 61 will not rotate with the threaded rod 4, but only move upward or downward according to the threaded rod 4, which is convenient for clamping the workpiece. The rotatable connection between the rotating sleeve 61 and the threaded rod 4 can be realized by using the existing technology, which will not be repeated here.

[0043] It should be noted that, in order to reduce the friction between the limiting rod 63 and the guide channel steel 7 , the end of the limiting rod 63 can be set to be spherical to reduce the friction between the limiting rod 63 and the guide channel steel 7 .

[0044] like Figure 2 , Figure 3 As shown, the support assembly 5 includes a base plate and two support blocks 51 welded above the base plate; a rotating shaft 52 is provided between the two support blocks 51; a support head is provided on the rotating shaft 52, and the support head is used to support the workpiece; the base plate is fixedly connected to the base 1, and can be fixedly connected by bolts.

[0045] The support head includes a rotating block 55 , and a first support block 5451 and a second support block 5351 fixed at two ends of the rotating block 55 ; the first support block 5451 and the second support block 5351 are used to support different types of workpieces.

[0046] A through hole corresponding to the rotating shaft 52 is provided at the center of the rotating block 55, and the rotating block 55 is rotatably arranged on the rotating shaft 52 through the through hole. It should be noted that in order to prevent the rotating block 55 from moving laterally along the rotating shaft 52, a stopper needs to be provided on the rotating shaft 52, for example, a snap ring is provided on both sides of the rotating block 55 (a corresponding snap groove needs to be provided on the rotating shaft 52), and the snap ring prevents the rotating block 55 from moving laterally.

[0047] The rotating block 55 is also provided with a corresponding limiting assembly for fixing the rotating block 55. In the present application, a limiting pin 56 can be provided on the supporting block 51, the limiting assembly is a limiting pin 56, and a limiting hole corresponding to the limiting pin 56 is provided on each side of the through hole. Figure 3 As shown, a spring pin may be provided on the support block 51 on one side to facilitate limiting the rotation block 55 and prevent the rotation block 55 from rotating around the rotation axis 52 .

[0048] The first support block 5451 is an angle steel, which can be used to support cylindrical workpieces, such as cylindrical steel pipes, threaded steel, round steel, etc. Since the contact area between the angle steel and the rotating block 55 is small during welding, in order to increase the stability of the angle steel welding, it can be as follows Figure 3 As shown, a round steel is added on each side of the angle steel. The round steel and the angle steel are fixed by high full welds, and then the round steel and the rotating block 55 are fixed by high full welds, thereby increasing the stability between the angle steel and the rotating block 55.

[0049] The second support block 5351 is a U-shaped steel, which can be used to support a square workpiece, such as a square steel. The type of the support block 51 can be flexibly selected by rotating the block 55 .

[0050] The bottom of the base 1 is further provided with supporting legs 11 to increase the stability of the base 1 .

[0051] Working process:

[0052] First, determine the type of workpiece, determine the support block 51 according to the type of workpiece, and after determining the support block 51, insert the limit pin 56 into the corresponding pin hole to fix the rotating block 55. Then rotate the threaded rod 4 through the handle 41 to move the clamping block 62 downward, thereby clamping the workpiece to facilitate subsequent welding of the workpiece.
