[0048] To make the purpose, technical solution and advantages of the present utility model clearer and more definite, the following further details the present utility model by way of examples with reference to the accompanying drawings. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

Therefore, it cannot be understood as a limitation to the present invention. In addition, "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is more than two.

[0050] Please refer to Figures 1 to 5 , the present utility model provides a welding positioner device, including a main body 5 of the positioner, a support rail 1, an L-shaped bracket 2 and a welding torch adjustment assembly 3.

[0051] Among them, at least two support rails 1 are provided, and a guide groove 101 is provided on the support rail 1. The main body 5 of the positioner is placed on the support rail 1. At least two L-shaped brackets 2 are provided, and the L-shaped brackets 2 are all arranged in parallel. At the same time, the horizontal parts of the L-shaped brackets 2 are all movably connected to multiple support rails 1. The welding torch adjustment assembly 3 is arranged on the vertical part of the L-shaped bracket 2, which is used to install the welding torch and enable the angle of the welding torch to be adjusted based on the welding requirements. After the welding torch is installed, it is ensured that the welding torch is located on one side of the welded part.

[0052] When the welding positioner device of the present utility model is needed to weld a reinforcing ring plate to a steel pipe 4, one end of the steel pipe 4 spot-welded with the reinforcing ring plate is fixed on the chuck of the main body 5 of the positioner. When the turntable rotates to a direction perpendicular to the horizontal plane, the axis of the steel pipe 4 is exactly parallel to the horizontal plane. And because the number of L-shaped brackets 2 is more than one, after the welding torch is installed on the welding torch adjustment assembly 3, there are multiple welding torches distributed along the length direction of the steel pipe 4 on one side of the steel pipe 4. Thus, multiple reinforcing ring plates can be welded firmly to the outer wall of the steel pipe 4 at the same time, thereby being able to solve the problem that the welding torches of the existing welding positioner cannot weld multiple areas existing along the length direction on the welded part at the same time, and improving the welding efficiency of metal components and the production efficiency of products.

[0053] In addition, since the L-shaped brackets 2 can all move along the length direction of the support rail 1, the distance between the welding torches can be adjusted, making the welding operation more flexible.

[0054] As Figure 4 shown, in a preferred embodiment of the present invention, each of the L-shaped brackets 2 includes a longitudinal beam 201, a column 202, and a sliding portion 203.

[0055] Among them, the sliding portion 203 can be a slider; the column 202 is vertically arranged on the longitudinal beam 201; the bottom of the longitudinal beam 201 is connected to the aforementioned sliding portion 203, and the sliding portion 203 is in sliding fit with the guide groove 101, so as to ensure that the L-shaped bracket 2 moves along the support rail 1.

[0056] In a preferred embodiment of the present invention, each of the L-shaped brackets 2 further includes a driving mechanism 204 and a sliding bracket 205.

[0057] Among them, the driving mechanism 204 can be a cylinder or a hydraulic cylinder, which is fixedly installed at the top of the column 202 and has a telescopic rod that extends downward; and the sliding bracket 205 is slidably arranged on one side surface of the column 202 facing the workpiece to be welded, and the sliding bracket 205 is connected to the telescopic rod.

[0058] In the present invention, the welding torch adjusting assembly 3 is connected to the sliding bracket 205. Therefore, when the driving mechanism 204 operates, the welding torch installed on the welding torch adjusting assembly 3 can move up or down together with the sliding bracket 205. Thus, before the welding operation starts, the welding torch can be controlled to move to the welding position (weld seam position), and after the welding is completed, the welding torch can be made to leave the welding position, facilitating the transfer of the welded metal component.

[0059] As Figure 5 shown, in a preferred embodiment of the present invention, the welding torch adjusting assembly 3 includes a guide rod 31, a first sleeve 32, a second sleeve 33, a first connecting rod 34, and a welding torch clamp 35.

[0060] Among them, the guide rod 31 is arranged on the sliding bracket 205, and the guide rod 31 is parallel to the longitudinal beam 201; the first sleeve 32 is movably sleeved on the guide rod 31; the second sleeve 33 is connected to the first sleeve 32; the first connecting rod 34 is movably passed through the second sleeve 33, and the first connecting rod 34 is parallel to the support rail 1; the welding torch clamp 35 is connected to the first connecting rod 34 and is used for clamping the welding torch.

[0061] It can be seen that after the welding torch (not shown in the attached drawings) is clamped on the welding torch fixture 35, by moving the first connecting rod 34, the position of the welding torch in the direction of the length of the support rail 1 can be adjusted; and since the second sleeve 33 is connected to the first sleeve 32 through a connecting member, by moving the first sleeve 32, the position of the welding torch in the direction of the longitudinal beam 201 can be adjusted. Thus, the use of the welding torch adjusting assembly 3 can adjust the position of the welding torch in the horizontal direction to meet the requirements of welding operations.

[0062] In a preferred embodiment of the present invention, the guide rod 31 is a cylindrical guide rod 31, whereby the first sleeve 32 can rotate on the guide rod 31, so that the position of the welding torch in the vertical direction can be adjusted, and the welding operation can be more flexible.

[0063] As Figure 5 shown, in a preferred embodiment of the present invention, the welding torch fixture 35 includes a second connecting rod 351, a first clamping plate 352, a first positioning rod 353, a second clamping plate 354 and a second positioning rod 355.

[0064] Among them, the second connecting rod 351 is perpendicular to the first connecting rod 34 and is arranged at the end of the first connecting rod 34. The setting of the second connecting rod 351 makes the welding torch closer to the welding place, so that the telescopic stroke of the telescopic rod of the driving mechanism 204 does not need to be too long, which helps to reduce the volume size of the L-shaped bracket 2.

[0065] Among them, both the first clamping plate 352 and the second clamping plate 354 are used to clamp the welding torch. Specifically, the first clamping plate 352 is fixedly arranged at the lower end of the second connecting rod 351, and the second clamping plate 354 is arranged opposite to the first clamping plate 352.

[0066] Among them, the first positioning rod 353 is vertically and fixedly arranged inside the first clamping plate 352, and the second clamping plate 354 is movably sleeved on the first positioning rod 353; the second positioning rod 355 is vertically and fixedly arranged inside the second clamping plate 354, and the second positioning rod 355 movably passes through the first clamping plate 352. The settings of the first positioning rod 353 and the second positioning rod 355 ensure that the second clamping plate 354 can move relative to the first clamping plate 352, and at the same time, during the movement of the second clamping plate 354, it is always parallel to the first clamping plate 352, which is convenient for clamping the welding torch.

[0067] Further, nuts are sleeved on the ends of the first positioning rod 353 passing through the second clamping plate 354 and the second positioning rod 355 passing through the first clamping plate 352. After the welding torch is clamped by the first clamping plate 352 and the second clamping plate 354, the second clamping plate 354 is fixed by the nuts, so that the distance between the second clamping plate 354 and the first clamping plate 352 will not change during the welding operation, thereby ensuring that the welding torch will not fall off the fixture and reducing the potential safety hazards during the operation.

[0068] In a preferred embodiment of the present utility model, sponge layers are provided on the inner sides of the first clamping plate 352 and the second clamping plate 354. The provision of the sponge layers can prevent the welding torch from being damaged by the welding torch fixture 35.

[0069] As Figure 1 and Figure 2 shown, in a preferred embodiment of the present utility model, a guiding strip 206 is provided on one side surface of the column 202 facing the workpiece to be welded; the back of the sliding bracket 205 is slidably connected to the guiding strip 206. The guiding strip 206 is used to limit the movement of the sliding bracket 205 in the horizontal direction, and can ensure the welding accuracy and welding quality when the welding torch performs the welding operation.

[0070] As Figure 1 and Figure 3 shown, in a preferred embodiment of the present utility model, magnetic seats 6 are provided on the support rail 1 on both sides of the L-shaped bracket 2. When the magnetic seats 6 are adsorbed on the upper part of the support rail 1, they can limit the movement of the L-shaped bracket 2, thereby ensuring the welding quality and reducing the potential safety hazards during the welding operation.

[0071] In summary, the present utility model sets multiple support rails for supporting the main body of the positioner, and multiple L-shaped brackets that are parallel and used for installing the welding torch adjustment assembly and the welding torch are provided on the support rails. Thus, when multiple regions existing along the length direction on the workpiece to be welded need to be welded, multiple welding torches with adjustable spacing exist on the same side of the workpiece to be welded, so that multiple regions existing along the length direction on the workpiece to be welded can be welded simultaneously, improving both the welding efficiency of the metal component and the production efficiency of the product.

[0072] It should be understood that the application of the present utility model is not limited to the above examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
