Technical Field

[0001] This utility model relates to the field of welding positioner technology, and in particular to a welding positioner that facilitates the replacement of welding heads. Background Technology

[0002] Welding positioners have quietly become an indispensable piece of equipment in the manufacturing industry. They are essential for achieving semi-automatic or fully automatic welding in manufacturing welding production.

[0003] An automatic welding positioner is disclosed in patent CN115846982B.

When welding disc-shaped workpieces, it can drive the workpiece to move along the X and Y axes. By simultaneously or separately adjusting the vertical pitch and rotating the circumferential direction, combined with a welding torch, rapid and efficient circumferential welding operations can be achieved, greatly saving manual labor, improving work efficiency, and ensuring welding quality. Furthermore, its manufacturing process is simple and inexpensive. When operators weld workpieces, the generated fine welding slag or dust can be collected into the cavity of the substrate under negative pressure, achieving the purpose of slag collection and improving the working environment. However, the following problems still exist in this patent:

However, if the welding head of the welding torch is not replaced after long-term use, it is easy to cause welding errors. In addition, the welding torch and the welding head are generally fixedly connected, which is not convenient to replace. Each time it needs to be replaced, the welding torch needs to be replaced, which is both wasteful and troublesome.

[0005] To address the above problems, a welding positioner that facilitates the replacement of welding heads needs to be designed to overcome these issues. Utility Model Content

A slide plate 402 is provided on the upper side of the slider 401, and a support plate 403 is provided on the upper side of the slide plate 402. An L-shaped support plate 404 is provided near one end of the support plate 403. A positioning hole 411 and a slot 412 are respectively provided at one end of the L-shaped support plate 404 and the support plate 403, and the positioning hole 411 and the slot 412 are connected at right angles. An L-shaped connecting plate 409 is provided on the outer wall near the positioning hole 411. An electric telescopic rod 410 is provided on the top of the L-shaped connecting plate 409. A protruding locking block 414 is embedded inside the slot 412. A spring 413 is provided at one end of the protruding locking block 414, and a first positioning block 406 is provided at one end of the spring 413.

[0027] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, a welding head 408 is installed between the first positioning block 406 and the L-shaped support plate 404. A threaded mounting rod 415 is installed at one end of the welding head 408, and a motor 405 is installed at the top of the threaded mounting rod 415. Four sets of L-shaped connecting plates 409 are provided, four sets of electric telescopic rods 410 are provided, four sets of positioning holes 411 are provided, four sets of slots 412 are provided, two sets of first positioning blocks 406 are provided, and four sets of protruding locking blocks 414 are provided. The operating frame 2 is fixedly installed between itself and the welding positioner body 1. The slide rail 3 is fixedly connected to the operating frame 2. The slider 401 is slidably connected to the slide rail 3. The slider 401 is fixedly connected to the slide plate 402. The slide plate 402 is connected to the support plate 403. The following components are fixedly connected: support plate 403 is fixedly connected to L-shaped support plate 404; two sets of L-shaped connecting plates 409 are fixedly connected to L-shaped support plate 404; two sets of L-shaped connecting plates 409 are fixedly connected to support plate 403; electric telescopic rod 410 is fixedly connected to L-shaped connecting plate 409; spring 413 is fixedly connected to first positioning block 406; protruding locking block 414 is fixedly connected to spring 413; protruding locking block 414 is engaged with locking groove 412; electric telescopic rod 410 is engaged with protruding locking block 414; welding head 408 is detachably installed with first positioning block 406; welding head 408 is detachably installed with L-shaped support plate 404; threaded mounting rod 415 is threadedly connected to welding head 408.

[0028] The operating frame 2 is vertically fixed to the side wall of the welding positioner body 1 with high-strength bolts to ensure that the horizontality error of the operating frame 2 is ≤0.5mm / m;

[0029] Among them, two parallel slide rails 3 are installed on the upper surface of the operating frame 2. The surface of the slide rails needs to be hardened and laser calibration is used to ensure that the parallelism error is ≤0.1mm.

[0030] Among them, the threaded mounting rod 415 of the welding head 408 is screwed into the threaded hole at the output end of the motor 405, and after tightening, thread fastening adhesive is applied.

[0031] Among them, the neck of the welding head 408 is clamped by two sets of first positioning blocks 406, and the clamping surface is covered with polyurethane anti-slip pads to ensure that the clamping force is ≥200N.

[0032] In this process, the positioning pin of the new welding head 408 is aligned with the positioning hole 411 of the support plate 403, and pushed along the slide rail 3 to the limit stop. The welding head 408 is rotated ninety degrees so that it enters the locking position of the slot 412. The electric telescopic rod 410 extends automatically and pushes the protruding block 414 into the slot 412.

[0033] The working process of this utility model is as follows: Using the welding positioner designed for easy replacement of welding heads, the main body 1 of the welding positioner is connected to an external power source to operate normally and perform welding operations on the objects to be welded. When the welding head 408 needs to be replaced, the electric telescopic rod 410 is retracted via an external controller, causing one end of the rod to move away from the slot of the protruding locking block 414. By pulling the two sets of first positioning blocks 406 in the opposite direction to the L-shaped support plate 404 and support plate 403, the protruding locking block 414 at one end of the first positioning block 406 disengages from the slot 412, allowing the first positioning block 406 to move away from the welding head 408. The welding head 408 can then be disassembled by rotating it to separate it from the threaded mounting rod 415. A new welding head 408 can then be replaced by rotating it. The welding head 408 is installed on the lower outer wall of the threaded mounting rod 415 by rotating it. By locking the protruding locking block 414 at one end of each of the two sets of first positioning blocks 406 into the slot 412, the electric telescopic rod 410 is extended by the external controller, which drives the locking block at one end to lock into the slot opened on the upper side of the protruding locking block 414, thus limiting its position. This facilitates the connection between the first positioning block 406 and the L-shaped support plate 404, and the connection between the first positioning block 406 and the support plate 403, thus limiting the position of the welding head 408 and facilitating its replacement. The operation is simple and does not require tools to remove the screws, which improves the speed of replacing the welding head 408. Furthermore, by pushing the slider 401, it slides along the inner wall of the slide rail 3, which drives the welding head 408 to move in position, making it easy to adjust and use as needed, thus improving the efficiency of the welding positioner body 1.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
