Description

Technical Field

[0001] This invention relates to the field of workpiece fixing technology, and more particularly to a sheet metal welding flipping device. Background Technology

[0002] Large sheet metal workpieces present numerous welding challenges, including numerous parts, large size, heavy weight, difficulty in flipping, and susceptibility to deformation. Welders need to spend a significant amount of time and manpower repeatedly flipping the workpieces to be welded, which is quite cumbersome.

[0003] The prior art discloses a welding and flipping device for large sheet metal workpieces. The welding rotating frame is provided with positioning threaded holes. The welding rotating frame and the welding base frame are connected as a whole by a rotating shaft and a bushing. The rotating shaft can rotate within the bushing. The welding plate of the rotating shaft has multiple round holes. The rotating plate of the fixed frame has multiple round holes that correspond one-to-one with the round holes of the welding plate of the rotating shaft. The workpiece is fixed on the welding rotating frame through the positioning threaded holes. After the welding rotating frame flips the workpiece, it is fixed by inserting pins into the round holes of the rotating plate of the fixed frame and the round holes of the welding plate of the rotating shaft.

[0004] However, using the above method, which involves setting fixed positioning threaded holes on the welding rotating frame to fix sheet metal workpieces, can only fix sheet metal workpieces of a single size type. It cannot fix sheet metal workpieces of different sizes as needed, thus limiting its applicability. Summary of the Invention

Detailed Implementation

[0028] The first embodiment of this application is as follows:

[0029] Please see Figures 1-2 ,in, Figure 1 This is a schematic diagram of the overall structure of the first embodiment of the present invention. Figure 2 yes Figure 1 A magnified view of detail A.

[0030] This invention provides a sheet metal welding flipping device, comprising a base 101 and a clamping assembly 102; the clamping assembly 102 includes two support plates 103, a rotating shaft 104, a flipping frame 105, a rotating mechanism 106, multiple clamping mechanisms 107, and multiple suction cups 108; the clamping mechanism 107 includes a first screw 109, a first knob 110, a top block 111, and an anti-slip pad 112; the rotating mechanism 106 includes a worm gear 113, a bracket 114, a worm 115, and a handle 116; the aforementioned solution solves the problem that existing sheet metal welding flipping devices can only fix sheet metal workpieces of a single size.

[0031] In this specific embodiment, the base 101 is used to mount the clamping assembly 102, and the clamping assembly 102 is used to clamp and mount the sheet metal workpiece for welding.

[0032] The two support plates 103 are fixedly connected to the base 101 and are located on the top of the base 101 respectively; the rotating shaft 104 is rotatably connected to the two support plates 103 and is located on one side of the two support plates 103; the flipping frame 105 is fixedly connected to the rotating shaft 104 and is located on one side of the rotating shaft 104; the rotating mechanism 106 is disposed on one side of the rotating shaft 104; a plurality of clamping mechanisms 107 are disposed on the flipping frame 105; the first screw 109 is threadedly connected to the flipping frame 105 and passes through the flipping frame 105; the first knob 110 is fixedly connected to the first screw 109 and is located on one side of the first screw 109; the top block 111 is rotatably connected to the first screw 109 and is located on one side of the first screw 109; the anti-slip pad 112 is fixedly connected to the top block 111 and is located on one side of the top block 111. Two support plates 103 are disposed on the top of the base 101 for rotatably mounting the rotating shaft 104. The flipping frame 105 is fixed on the rotating shaft 104 and can therefore rotate with the rotating shaft 104. The rotating mechanism 106 is used to rotate the rotating shaft 104 and can lock the rotating shaft 104 to prevent it from rotating. Multiple clamping mechanisms 107 are used to clamp and mount the sheet metal workpiece inside the flipping frame 105. The first knob 110 is used to facilitate rotating the first screw 109. Rotating the first screw 109 can drive the top block 111 to move. The top block 111 is used to hold the sheet metal workpiece. The anti-slip pad 112 is used to increase the friction between the top block 111 and the sheet metal workpiece. In specific use... In use, the sheet metal workpiece is placed inside the flipping frame 105, and then the appropriate position and number of clamping mechanisms 107 are selected to clamp the sheet metal workpiece. When using the clamping mechanism 107, the first knob 110 is rotated so that the first screw 109 drives the top block 111 to abut against the outer wall of the sheet metal workpiece. Then, as needed, the rotating mechanism 106 is used to rotate the rotating shaft 104, thereby driving the flipping frame 105 to rotate to a suitable angle, and driving the internally clamped sheet metal workpiece to rotate to a suitable angle. Since multiple adjustable clamping mechanisms 107 are used to clamp the sheet metal workpiece, sheet metal workpieces of different sizes and types can be clamped, thereby solving the problem that existing sheet metal welding flipping devices can only fix sheet metal workpieces of a single size and type.

[0033] Secondly, the plurality of suction cups 108 are fixedly connected to the flipping frame 105 and are located on one side of the flipping frame 105. The plurality of suction cups 108 can hold sheet metal workpieces, and together with the plurality of clamping mechanisms 107, they can more stably clamp the sheet metal workpieces inside the flipping frame 105.

[0034] Meanwhile, the worm gear 113 is fixedly connected to the rotating shaft 104 and located on one side of the rotating shaft 104; the bracket 114 is fixedly connected to the base 101 and located on top of the base 101; the worm 115 is rotatably connected to the bracket 114 and meshes with the worm gear 113. The bracket 114 is used to rotatably mount the worm 115. Rotating the worm 115 can drive the worm gear 113 to rotate, and the worm gear 113 can drive the rotating shaft 104 to rotate, ultimately driving the clamped sheet metal workpiece to rotate. Since the worm gear 113 and worm 115 have self-locking properties, the rotating shaft 104 can be locked after rotation and adjustment.

[0035] Additionally, the handle 116 is fixedly connected to the worm gear 115 and is located on one side of the worm gear 115. The handle 116 is used to increase the lever arm, allowing the worm gear 115 to be rotated with less effort.

[0036] In this embodiment, a sheet metal welding flipping device is described. Two support plates 103 are disposed on the top of the base 101 for rotatably mounting the rotating shaft 104. The flipping frame 105 is fixed on the rotating shaft 104 and can therefore rotate with the rotating shaft 104. The rotating mechanism 106 is used to rotate the rotating shaft 104 and can lock the rotating shaft 104 to prevent it from rotating. Multiple clamping mechanisms 107 are used to clamp and mount the sheet metal workpiece inside the flipping frame 105. The first knob 110 is used to facilitate the rotation of the first screw 109. Rotating the first screw 109 can drive the top block 111 to move. The top block 111 is used to support the sheet metal workpiece. The anti-slip pad 112 is used to increase the distance between the top block 111 and the sheet metal workpiece. The friction force; in specific use, the sheet metal workpiece is placed inside the flipping frame 105, and then the appropriate position and number of clamping mechanisms 107 are selected to clamp the sheet metal workpiece. When using the clamping mechanism 107, the first knob 110 is rotated so that the first screw 109 drives the top block 111 to abut against the outer wall of the sheet metal workpiece. Then, as needed, the rotating mechanism 106 is used to rotate the rotating shaft 104, thereby driving the flipping frame 105 to rotate to a suitable angle, and driving the internally clamped sheet metal workpiece to rotate to a suitable angle. Since multiple adjustable clamping mechanisms 107 are used to clamp the sheet metal workpiece, sheet metal workpieces of different sizes and types can be clamped, thereby solving the problem that the existing sheet metal welding flipping device can only fix a single size and type of sheet metal workpiece.

[0037] The second embodiment of this application is as follows:

[0038] Based on the first embodiment, please refer to Figures 3-4 ,in, Figure 3This is a schematic diagram of the overall structure of the second embodiment of the present invention. Figure 4 yes Figure 3 A magnified view of detail B.

[0040] In this specific embodiment, the reinforcing mechanism 201 is disposed on one side of the rotating shaft 104. Since the rotating shaft 104 is only locked by the worm gear 113 and the worm 115 after rotation, it is not stable enough. Therefore, the reinforcing mechanism 201 is provided to further lock the rotating shaft 104.

[0041] The second screw 202 is threadedly connected to the support plate 103 and passes through the support plate 103; the friction block 203 is rotatably connected to the second screw 202 and is located on one side of the second screw 202; the friction disk 204 is fixedly connected to the rotating shaft 104 and is located on one side of the rotating shaft 104. The friction coefficient of the friction block 203 and the friction disk 204 is relatively large. When it is necessary to rotate the rotating shaft 104, the second screw 202 is turned, causing the friction block 203 to move away from the friction disk 204. When it is necessary to lock the rotating shaft 104, the second screw 202 is turned, causing the friction block 203 to press against the friction disk 204, thereby locking the rotating shaft 104.

[0042] Secondly, the second knob 205 is fixedly connected to the second screw 202 and is located on one side of the second screw 202. The second knob 205 is used to facilitate the rotation of the second screw 202.

[0043] In this embodiment, a sheet metal welding flipping device is described. The friction block 203 and the friction disk 204 have a large coefficient of friction. When it is necessary to rotate the rotating shaft 104, the second screw 202 is turned to drive the friction block 203 away from the friction disk 204. When it is necessary to lock the rotating shaft 104, the second screw 202 is turned to drive the friction block 203 to press against the friction disk 204, thereby locking the rotating shaft 104.

[0044] The third embodiment of this application is as follows:

[0045] Based on the second embodiment, please refer to Figures 5-6 ,in, Figure 5 This is a schematic diagram of the overall structure of the third embodiment of the present invention. Figure 6 This is a front view of the entire third embodiment of the present invention.

[0046] The sheet metal welding flipping device provided by the present invention further includes a support component 301; the support component 301 includes a plurality of universal wheels 302 and two braking mechanisms 303; the braking mechanism 303 includes a third screw 304, a chassis 305 and a third knob 306.

[0047] In this specific embodiment, the support component 301 is disposed on the base 101. The support component 301 is used to support the base 101 and facilitates movement.

[0048] The multiple casters 302 are rotatably connected to the base 101 and are located at the bottom of the base 101; the two braking mechanisms 303 are respectively disposed on the base 101. The multiple casters 302 facilitate the movement of the base 101, and the two braking mechanisms 303 are arranged one in front of the other to stably stop the base 101.

[0049] Secondly, the third screw 304 is threadedly connected to the base 101 and passes through the base 101; the chassis 305 is rotatably connected to the third screw 304 and is located at the bottom of the third screw 304; the third knob 306 is fixedly connected to the third screw 304 and is located at the top of the third screw 304. When the base 101 needs to be stably parked, the third knob 306 is rotated, causing the third screw 304 to drive the chassis 305 down to the ground, thus stopping the base 101 stably. When the base 101 needs to be moved, the third knob 306 is rotated, causing the third screw 304 to drive the chassis 305 up away from the ground.

[0050] The sheet metal welding flipping device described in this embodiment, when the base 101 needs to be stably parked, rotates the third knob 306, causing the third screw 304 to drive the chassis 305 to move down and abut against the ground, so that the base 101 is stably stopped. When the base 101 needs to be moved, rotates the third knob 306, causing the third screw 304 to drive the chassis 305 up and away from the ground.
