[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] Reference Figures 1 to 4 The operating rotary table for sheet metal processing comprises a base frame 1, a workbench 2, a gantry 3 and a mounting frame 4, wherein the workbench 2 and the gantry 3 are both arranged on the base frame 1, and the gantry 3 spans above the workbench 2. The mounting frame 4 is arranged on the gantry 3, and the mounting frame 4 is used to install the welding head of a handheld welding machine, or the cutting head of a handheld cutting machine. Preferably, the handheld welding machine is a handheld laser welding machine, and the handheld cutting machine is a handheld plasma cutting machine.

[0027] like Figure 1 As shown, the mounting frame 4 includes an upper mounting frame 41, a connecting frame 43 and a lower mounting frame 42. The upper mounting frame 41 is mounted on the crossbeam of the gantry 3, and the upper mounting frame 41 can move back and forth along the crossbeam, and can also be locked and fixed on the crossbeam. The upper part of the connecting frame 43 is connected to the upper mounting frame 41 in a rotatable and lockable manner in the vertical direction to facilitate the adjustment of the angle relative to the upper mounting frame 41. The lower mounting frame 42 is connected to the lower part of the connecting frame 43 and can be moved back and forth. The lower mounting frame 42 is provided with a mounting position for installing a welding head or a cutting head to achieve linear movement, which is convenient for linear cutting of sheet metal parts. In addition, the gantry 3 can adjust the height by loosening the hand screws, operating the crossbeam to move up and down to the appropriate position and then tightening it to facilitate the adjustment of the height of the welding head or the cutting head.

[0028] For easy operation, the lower mounting frame 42 is also provided with a switch mechanism at the mounting position that can operate the switch button of the welding head or cutting head. The switch button on the welding head or cutting head is mainly operated by the action of the mechanical structure. Furthermore, the action of the switch mechanism is connected to the pedal 10 provided on the base frame 1 through a steel wire pull line 20, so that the switch mechanism can be controlled by the foot, freeing the hands to facilitate the operation of the lower mounting frame 42 to move in a straight line. Of course, a simpler structure can be adopted, and the gun-shaped welding head or cutting head can be directly bound to the lower mounting frame 42. When holding the welding head or cutting head, the switch button can be directly pressed, and the lower mounting frame 42 can be pulled at the same time to move in a straight line together with the restriction of the lower mounting frame 42. For sheet metal parts with more complex structures, the welding head or cutting head needs to be removed and welded or cut by hand.

[0029] The workbench 2 of the above embodiment can be rotated and locked relative to the base frame 1, which is not shown in the accompanying drawings. Its structure is mainly achieved by threading a locking screw with its tail pointing to the workbench 2 on the base frame 1. When tightened, the tail presses against the workbench 2 to achieve locking. After loosening, the workbench 2 can be rotated to a suitable position.

[0030] like Figure 2 , Figure 3 and Figure 4 The workbench 2 shown in the figure has a structure including a shell 21, a panel 22 and a layer plate 23. The panel 22 is fixedly connected to the upper part of the bottom shell, and the layer plate 23 is fixedly connected to the inside of the shell 21 and has a spacing between it and the panel 22. A plurality of support components 5, a locking component 6 and a plurality of interference components 7 are also provided on the workbench 2. The support component 5 is arranged on the bottom surface of the layer plate 23 and extends from the bottom to the top through the layer plate 23 and the panel 22 to the outside of the panel 22. Each support component 5 can be independently extended up and down to support each bottom surface of the sheet metal. The locking component 6 is arranged between the panel 22 and the layer plate 23 to lock each support component 5 when it is at different extension lengths. The interference component 7 is arranged on the panel 22. The interference component 7 can move back and forth along the radial direction of the workbench 2 and can be locked to interfere with other surfaces other than the bottom surface of the sheet metal.

[0031] When placing a sheet metal part with a more complex structure, press the sheet metal part appropriately. At this time, the support component 5 on the bottom surface will shrink automatically according to the contact situation until it matches the shape of the bottom surface; operate the locking component 6 to lock and fix the state of the support component 5, and then use the interference component 7 to interfere with and limit the other surfaces of the sheet metal part from all sides and lock it, finally positioning and fixing the sheet metal part.

[0032] like Figure 3 and Figure 4As shown, the support assembly 5 includes a support rod 51, a bottom sleeve 52 and an elastic member 53. The bottom sleeve 52 is fixedly connected to the bottom surface of the layer plate 23 by screws or adhesive. The support rod 51 passes through the layer plate 23 and the panel 22 from bottom to top, and the upper part extends to the outside of the panel 22. The two ends of the elastic member 53 respectively abut the support rod 51 and the bottom sleeve 52. The elastic member 53 adopts a spring to keep the upper part of the support rod 51 extending outside the panel 22. The layer plate 23 is provided with a through hole for the support rod 51 to pass through. The diameter of the tail end of the support rod 51 is larger than the diameter of the through hole, so that the entire support rod 51 will not pass through the through hole, and each support rod 51 maintains a certain extension height.

[0033] like Figure 3 and Figure 4 As shown, the locking assembly 6 includes a turntable 61, a pressure plate 62, a plurality of pressure sleeves 63 and an adjusting member 64. The through hole on the layer plate 23 for the support rod 51 to pass through is a tapered hole. The number of the pressure sleeves 63 is the same as the tapered holes and they are respectively and one-to-one matched and placed at the tapered mouth of each tapered hole. The pressure plate 62 is arranged between the panel 22 and the layer plate 23 and can move up and down, and can drive all the pressure sleeves 63 to move synchronously. The turntable 61 is arranged between the panel 22 and the pressure plate 62, and the turntable 61 can rotate and move up and down.

[0034] A plurality of limiting posts 611 are evenly arranged around the rotating disk 61, and a plurality of inclined strip grooves 211 are evenly arranged around the shell wall of the housing 21, and the number of limiting posts 611 is the same as that of the strip grooves 211. The limiting posts 611 are matched and connected in the strip grooves 211. When the rotating disk 61 rotates forward and reverse, it is limited by the strip grooves 211 and will press or move away from the pressure plate 62 respectively. When pressing, it will push the pressure plate 62 to move downward synchronously, and the pressure plate 62 pushes all the pressing sleeves 63 to move downward synchronously. The pressing sleeves 63 are limited by the tapered mouth of the tapered hole and move toward the axis of the tapered hole, thereby clamping the support rod 51 to fix it.

[0035] like Figure 4 As shown, two through grooves 621 are symmetrically arranged on the pressure plate 62 at the through hole for the support rod 51 to pass through, and the pressure sleeve 63 includes two symmetrically arranged half-side sleeves, and a T-block 631 is arranged at the top of the half-side sleeve. The vertical parts of the T-blocks 631 of the two half-side sleeves are respectively matched and connected in the two through grooves 621, so that the pressure plate 62 drives the pressure sleeve 63 to move up and down.

[0036] like Figure 2 and Figure 4 As shown, the adjustment member 64 includes a hand screw 641 and a pull ring 642. The hand screw 641 is threadedly connected to the housing 21. The pull ring 642 is hinged to the tail of the hand screw 641 so that it will not rotate with the hand screw 641. The pull ring 642 is sleeved on one of the limit posts 611 to pull or push the limit post 611.

[0037] The panel 22 is evenly provided with a plurality of radially arranged sliding grooves 221, and the abutment assembly 7 is slidably connected to the sliding grooves 221 and can be locked by screws. Figure 5 As shown, the abutment assembly 7 includes a base 71, a telescopic rod 72 and a abutment head 73. The base 71 can be slidably connected to the slide groove 221 and can be locked by screws. The telescopic rod 72 can be moved up and down and connected to the base 71 and can be locked by hand screws. The abutment head 73 can be rotatably connected to the top of the telescopic rod 72 and locked by screws to adjust the direction of the abutment head 73, so as to facilitate the abutment and pressing of surfaces of different directions on the sheet metal.

[0038] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
