The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The embodiment of the present invention provides a movable welding fixture with quick switching, such as Figure 1-4 As shown, it includes a base plate 1, a bracket 2 is installed on the surface of the base plate 1, a limiting sleeve 3 is rotatably installed on the top of the bracket 2, a connecting shaft 4 is rotatably installed on the inner side of the limiting sleeve 3, a connecting disk 5 is installed at the axial end of the connecting shaft 4, a connecting frame 6 is installed on the side of the connecting disk 5, six groups of connecting frames 6 are provided, and the six groups of connecting frames 6 are distributed on the surface of the connecting disk 5 in a circular array, a fixing plate 7 is installed at one end of the connecting frame 6 away from the connecting disk 5, a mounting frame 8 is installed on the side of the fixing plate 7 away from the connecting frame 6, a fixture body 9 is installed on the upper end of the mounting frame 8, the bracket 2 and the limiting sleeve 3 are each provided with two groups, connecting disks 5 are installed at both ends of the connecting shaft 4, a worm gear 10 is fixedly sleeved on the outer side of the connecting shaft 4, a worm 11 meshing with the worm gear 10 is rotatably installed on the side of the bracket 2, a motor 12 is installed on the side of the bracket 2, and the output of the motor 12 The output shaft is connected to the rod end of the worm 11, and a controller 13 is installed between the two groups of brackets 2. The controller 13 is electrically connected to the motor 12. The device is implemented by installing six different types of clamp bodies 9 on the connecting frame 6. When the clamp body 9 needs to be replaced, the motor 12 is first started through the controller 13. The motor 12 drives the worm 11 to rotate, and the worm wheel 10 drives the connecting shaft 4 to rotate under the action of the thread on the surface of the worm 11. The single rotation angle of the connecting shaft 4 is 60 degrees. At this time, the connecting disk 5 drives the connecting frame 6 to rotate, and the adapted clamp body 9 can be rotated to a horizontal position for use according to the welding workpiece. The device switches the clamp body 9 by rotation, eliminating the need to disassemble and assemble the clamp body 9, thereby effectively improving the convenience of replacing the clamp body 9.

[0026] The lower end of the clamp body 9 is connected with a card plate 14, and the mounting frame 8 is provided with two groups and is in an inverted L shape. The card plate 14 is embedded between the two groups of mounting frames 8, and the card plate 14 slides and snaps in from the front side of the mounting frame 8. A fixing frame 15 is installed at the bottom of the fixing plate 7, and a pull rod 16 is slidably installed on the inner side of the fixing frame 15. The inner end of the pull rod 16 is connected with a pin shaft 17, and the outer side of the pull rod 16 is sleeved with a first spring 18. The bottom of the card plate 14 is provided with a card slot adapted to the pin shaft 17, and the pin shaft 17 passes through the surface of the fixing plate 7 and is plugged into the bottom of the card plate 14. By providing the card plate 14, the card plate 14 is installed between the two groups of mounting frames 8 by sliding and clamping and is fixed by the pin shaft 17. When the clamp fails and needs to be disassembled for maintenance, the pull rod 16 can be pulled to pull the pin shaft 17 out of the card slot of the card plate 14, and then the clamp body 9 can be pulled horizontally to separate from the two groups of mounting frames 8 for removal. This installation method can make the disassembly and maintenance of the clamp body 9 easier and faster.

[0027] Pulleys 19 are rotatably installed on the upper and lower surfaces of the card plate 14. There are four groups of pulleys 19, which are distributed around the card plate 14. By installing the pulleys 19 on the upper and lower surfaces of the card plate 14, the pulleys 19 can convert the sliding friction between the card plate 14 and the mounting frame 8 into rolling friction, thereby making the disassembly and assembly of the clamp body 9 more labor-saving.

[0028] A fixing tube 20 is installed at the bottom of the clamp body 9, and electric wires are inserted into the interior of the fixing tube 20 and a plug 21 is installed at the bottom. The front sides of the card plate 14, the fixing plate 7 and the connecting frame 6 are all provided with placement grooves adapted to the fixing tube 20. A fixing frame 22 is installed on the top side of the bracket 2, and a slot 23 is installed at the upper end of the fixing frame 22. The slot 23 and the plug 21 are slidably connected. By providing the fixing tube 20, the fixing tube 20 can bundle the wires and limit the plug 21 to the inner side of the connecting frame 6, so as to realize the subsequent on-off connection between the plug 21 and the slot 23.

[0029] A groove is provided inside the plug 21, and two groups of gaskets 24 are installed in the groove. The two groups of gaskets 24 are connected by a second spring 25, and the second spring 25 is conductive. A conductive block 26 is connected to the side of one group of gaskets 24, and a conductive plate 27 is installed on the inner side of the slot 23. By providing the plug 21 and the slot 23, the plug 21 is located on the inner side of the connecting frame 6. When the connecting frame 6 rotates to switch the clamp body 9, the plug 21 of the clamp body 9 before use will be disengaged from the slot 23, and the plug 21 of the clamp body 9 to be used will be inserted into the slot 23. Through this setting, the power can be automatically turned on and off when the clamp body 9 is switched, thereby further improving the convenience of switching the clamp body 9.

[0030] The side surface of the conductive block 26 is set as an inclined surface, and the inner wall of the slot 23 is opened as an inclined groove. By setting both sides of the conductive block 26 as inclined surfaces, electricity is supplied to the plug 21 and the slot 23 through the contact between the conductive block 26 and the conductive plate 27. When the connecting frame 6 rotates, the side wall of the slot 23 will generate pressure on the conductive block 26, and the pressure will cause the conductive block 26 to retract into the inside of the plug 21, thereby achieving power off.

[0031] Two groups of electric cylinders 28 are installed on the top of the bracket 2, and an operating table 29 is installed on the top of the output shaft of the electric cylinder 28. The operating table 29 is located between the clamp bodies 9. By setting the electric cylinder 28, the electric cylinder 28 can push the operating table 29 up and down, thereby realizing the lifting and lowering adjustment of the operating table 29. This setting can make the operating table 29 more convenient to use.

[0032] A top plate 30 is installed on the top of the clamp body 9, and a ball 31 is installed on the upper surface of the top plate 30. By providing the top plate 30, when the clamp body 9 is removed, the clamp body 9 can be inverted and moved by sliding the ball 31 on the surface of the top plate 30, thereby making the movement and replacement of the clamp body 9 more labor-saving.
