DETAILED DESCRIPTION

[0023] The present invention will be described in detail below with reference to the accompanying drawings.

[0024] Combine Figures 1-4 As shown, the embodiment discloses a welding device capable of welding T-shaped and cross-shaped workpieces, including a frame, a tooling platform 11, a welding machine 6, a positioning clamping mechanism and a controller.

[0025] The frame includes a machine base 2 and a slide module. The slide module includes an X-axis module 9, a Y-axis module 7 and a Z-axis module 8 for driving the welding machine to move in three directions of XYZ. The X-axis module 9 and the tooling platform 11 are arranged on the machine base 2, the lower end of the Z-axis module 8 is installed on the X-axis module 9, the Y-axis module 7 is installed on the Z-axis module 8, and the welding machine 6 is installed on the Y-axis module 7. The X-axis module 9, the Y-axis module 7 and the Z-axis module 8 adopt existing technology.

[0026] The positioning and clamping mechanism is arranged on the tooling platform 11. There are four groups of positioning and clamping mechanisms. Each group of positioning and clamping mechanisms includes a positioning die 14 and a clamping device 5. The positioning die 14 is used to engage and position the profile 15. For example, a concave-convex structure matching the profile 15 is provided on the positioning die 14, so that the profile 15 is buckled on the positioning die 14 and can be combined into a T-shaped or cross-shaped workpiece with a fixed position. The clamping device is used to press the profile 15 against the corresponding positioning die 14. The positioning dies of the four groups of positioning and clamping mechanisms are arranged on the four sides of a cross. There are gaps between the four positioning dies 14, forming an area for the welding machine to operate. No side of the cross points to the frame. The travel of the Z-axis module 8 on the X-axis module 9 is located within a corner of the cross. As a result, when the profile 15 is clamped on the positioning die 14, the Z-axis module 8 has a large range of motion and does not interfere with the profile 15. The best effect is achieved when each side of the cross forms an angle of 45 degrees with the length direction of the tooling platform 11 .

[0027] like Figure 5 and Figure 6 As shown, each positioning die 14 is connected to the tooling platform 11 via four sets of positioning structures 10, arranged at the four vertices of a rectangle. The positioning structures 10 include a tapered column 102 fixed to the top surface of the tooling platform 11 and a tapered sleeve 103 fixed to the bottom surface of the positioning die 14. The tapered column 102 is fixed to the tooling platform 11 via a first bolt 101, and the tapered sleeve 103 is fixed to the positioning die 14 via a second bolt 104. The tapered sleeve 103 is fastened to the tapered column 102, and the contact surface between the tapered column 102 and the tapered sleeve 103 is a tapered surface. This not only facilitates the fastening of the tapered sleeve 103 onto the tapered column 102, but also ensures more accurate positioning after full fastening.

[0028] The pressing device 5 includes a pressing cylinder 13 and a pressing claw 12. The pressing cylinder 13 is an angle cylinder. The cylinder body of the angle cylinder is fixed on the tooling platform 11. The pressing claw 12 is fixed to the lower side of the pressing arm of the angle cylinder. During the rotation of the pressing arm, the pressing claw 12 has two states: rotating to the top of the corresponding positioning die 14 and deviating from the corresponding positioning die 14. When the pressing claw 12 rotates to the top of the corresponding positioning die 14, the angle cylinder drives the pressing arm to descend to press the profile 15.

[0029] A support frame 3 is installed on the extension line of each positioning die 14, located on the side of the positioning die 14 away from the center of the cross. One end of the support frame 3 is fixed to the tooling platform 11, and the other end is provided with a support column on the ground. When the profile is long, the support frame 3 can support the profile 15.

[0030] The controller controls the normal operation of the welder 6, X-axis module 9, Y-axis module 7, and Z-axis module 8. The emergency stop switch 4 is used to stop the welder 6, X-axis module 9, Y-axis module 7, and Z-axis module 8. The welder 6 is a laser welder, and two sets of emergency stop switches 4 are provided, one on each side of the tooling platform 11. A foot switch 1 is also located on the front of the machine base 2 to start and stop the welder 6. The control methods of the controller, emergency stop switch 4, and foot switch 1 all adopt existing technologies.

[0031] Working principle: When welding, the profile to be welded is placed on the positioning mold 14. Three positioning molds 14 are used to position three profiles 15 for a T-shaped workpiece, and four positioning molds 14 are used to position four profiles 15 for a cross-shaped workpiece. The profiles 15 are snapped into the positioning molds 14 and assembled into a workpiece of the corresponding shape. The profiles 15 are then pressed by the clamping device 5. Then the welder 6 can be started for welding, and the welder 6 can be controlled to move in the XYZ directions as needed.

[0032] The above embodiments are merely illustrative of this patent and do not limit its scope of protection. Those skilled in the art may also make partial changes thereto, and as long as they do not exceed the spirit of this patent, they are within the scope of protection of this patent.
