Description

Technical Field

[0001] This utility model relates to the field of welding positioner technology, specifically to a hand-cranked flip welding table. Background Technology

[0002] In existing welding processes, workpieces typically need to be welded at different angles to ensure a continuous and strong weld. A common solution is to fix the workpiece on a welding table or fixture, and then have the operator manually adjust the workpiece's angle.

[0003] However, most traditional welding stations have simple structures, and once the workpiece is fixed in position, it is difficult to rotate flexibly. Workers often need to frequently loosen the clamps and reposition the workpiece, which is not only time-consuming and labor-intensive, but also prone to causing the workpiece to shift during welding, affecting the welding quality. On the other hand, although some flip-type welding stations can adjust the workpiece angle, they often use complex electric drive mechanisms, which are costly and inconvenient to maintain, making them unsuitable for small and medium-sized workshops or occasions requiring flexible movement. In addition, existing manual flip-type structures generally lack reliable locking mechanisms. Once the workpiece is flipped to the target angle, it is difficult to keep it stable and fixed, which can easily lead to problems such as the flipping support shaking or angle deviation, resulting in reduced weld accuracy. Utility Model Content

[0004] In order to overcome the defects of the prior art, the present invention provides a hand-cranked flip welding table. By configuring a hand-cranked rotating component on the flipping seat, the operator only needs to manually crank to achieve smooth flipping of the workpiece, avoiding the tedious steps of frequent clamping and repositioning of traditional welding tables, and greatly improving work efficiency.

Detailed Implementation

[0019] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] like Figure 1-2 The illustrated hand-cranked rotating welding table includes a frame 1, a first rotating base 2, a second rotating base 3, and a rotating support 9. One end of the frame 1 has a first column 11, and the other end has a second column 12. The first rotating base 2 is rotatably mounted on the first column 11; the second rotating base 3 is rotatably mounted on the second column 12; the rotating support 9 is connected at both ends to the first rotating base 2 and the second rotating base 3, respectively, and is used to support the workpiece. By setting a hand-cranked rotating component and a locking component on the rotating base, the operator only needs to manually crank the hand-cranked rotating component to achieve smooth workpiece rotation, and locks it in place promptly when rotated to the target angle. This avoids the tedious steps of frequent clamping and repositioning required by traditional welding tables, significantly improving work efficiency and ensuring the stability of the workpiece welding position, thereby improving welding quality.

[0023] Furthermore, the top of the first column 11 is provided with a first bearing seat 4 and a first bearing installed therein. One side of the first tilting seat 2 is rotatably connected to the first bearing via a first rotating shaft 41, and the other side is connected to one end of the tilting bracket 9. This structure supports rotation through bearings, making the tilting process smoother, reducing manual operation resistance, and effectively extending the service life of the device.

[0024] Specifically, the top of the second column 12 is provided with a second bearing seat 5 and a second bearing installed therein. One side of the second tilting seat 3 is rotatably connected to the second bearing through a second rotating shaft 51, and the other side is connected to the other end of the tilting bracket 9. With symmetrical support at both ends, the tilting bracket 9 is subjected to balanced force during tilting, which can prevent the workpiece from shaking and improve the overall load-bearing stability.

[0025] In this embodiment, the first column 11 and the second column 12 are fixedly connected by a connecting beam 13, which can be welded to the column. This connection structure not only enhances the overall stability and rigidity of the frame, but also effectively distributes the force during workpiece flipping, preventing deformation of the column and thus ensuring the smooth operation and reliable load-bearing capacity of the flipping support.

[0026] Furthermore, the hand-cranked rotating assembly includes a handle 6, which is fastened to one end of a first rotating shaft 41 by a nut, and the other end of the first rotating shaft 41 is connected to a first tilting seat 2; alternatively, the handle 6 is fastened to one end of a second rotating shaft 51 by a nut, and the other end of the second rotating shaft 51 is connected to a second tilting seat 3. This hand-cranked structure has a simple design and intuitive operation, and can easily achieve workpiece tilting without external power, making it particularly suitable for small and medium-sized workshops or mobile welding applications.

[0027] Furthermore, the locking assembly includes an indexing hole 21 and a pin 72 formed on the first flip base 2 or the second flip base 3. By inserting the pin 72 into the indexing hole 21, the flip bracket 9 can be locked at the required angle, thereby ensuring the accuracy and safety of the welding operation.

[0028] Specifically, the first column 11 or the second column 12 is provided with a mounting plate 7, and the mounting plate 7 is provided with a positioning hole 71. The pin 72 is inserted into the positioning hole 71. When the positioning hole 71 is aligned with the indexing hole 21, the pin 72 is inserted into the positioning hole 71 and the indexing hole 21 in sequence, so as to lock and fix the first flip seat 2 or the second flip seat 3, so that the flip bracket 9 is accurately stopped at the target angle, effectively avoiding the weld offset caused by the workpiece sliding.

[0029] In this embodiment, multiple indexing holes 21 are arranged at intervals along the circumference of the first bearing seat 4 on the first tilting seat 2; or, multiple indexing holes 21 are arranged at intervals along the circumference of the second bearing seat 5 on the second tilting seat 3. This design with multiple indexing holes 21 enables multi-angle adjustment, allowing the welded workpiece to be flexibly positioned under different working conditions, significantly improving the applicability of the equipment.

[0030] Furthermore, the mounting plate 7 is also equipped with a resilient top column assembly, which includes a top column 8 and an elastic element 81. The elastic element 81 is sleeved on one end of the top column and connected to the mounting plate 7, applying elastic force to the top column 8 so that the top column 8 presses against the first flip seat 2 or the second flip seat 3 under the action of the elastic element 81. This design provides additional clamping force during the locking process, which can avoid loosening problems caused by workpiece weight or operational vibration, thereby further improving the stability of the flip bracket 9.

[0031] The flipping bracket 9 is equipped with multiple clamping cylinders 91 for holding the workpiece. Through the coordinated action of these multiple clamping cylinders 91, multi-point clamping of workpieces of different specifications can be achieved. This not only enables rapid workpiece clamping and release, reducing manual intervention and significantly improving work efficiency, but also effectively disperses clamping force, avoiding uneven stress on the workpiece caused by single-point clamping, thereby enhancing the stability and reliability of workpiece fixation. Simultaneously, this structure also improves the accuracy of workpiece positioning during welding, ensuring the consistency of weld quality.

[0032] Furthermore, a first connecting bracket 14 is provided on one side of the bottom of the frame 1, and a second connecting bracket 15 is provided on the other side; the bottom of the first connecting bracket 14 is provided with a first moving wheel 141, and the bottom of the second connecting bracket 15 is provided with a second moving wheel 151. The provision of moving wheels enables the welding table to have good mobility and flexibility, facilitating position adjustment within the workshop or use across workstations, thereby expanding the application scenarios of the device.

[0033] It should be noted that in this embodiment, there are two first connecting brackets 14, which are respectively fixed on both sides of the first column 11, and the bottom of each of the two first connecting brackets 14 is provided with a first moving wheel 141. Similarly, there are also two second connecting brackets 15, which are respectively fixed on both sides of the second column 12, and the bottom of each of them is provided with a second moving wheel 151. Through the above structural arrangement, the welding table is subjected to more balanced forces when moving, which can avoid tilting or instability caused by excessive force on one side, thereby improving the overall stability and safety of movement. Furthermore, the two first connecting brackets 14 can be connected to both sides of the first column 11 by welding, and the two second connecting brackets 15 can also be connected to both sides of the second column 12 by welding. This fixing method not only improves the firmness of the connection, but also enhances the overall rigidity of the column and the bottom of the frame 1, so that the welding table remains stable and reliable when bearing heavy workpieces.

[0034] In summary, this utility model of a hand-cranked flip welding table, by configuring a hand-cranked rotating component on the flipping base, allows the operator to smoothly flip the workpiece simply by manually cranking it, avoiding the tedious steps of frequent clamping and repositioning required by traditional welding tables, thus significantly improving work efficiency. Simultaneously, the locking component can promptly lock the flipping base after the flipping bracket 9 reaches the target angle, effectively preventing bracket wobbling or angle deviation, ensuring the stability of the welding position and the accuracy of the weld.

[0035] This utility model features a hand-cranked flip welding table with a simple structure and low cost, making it suitable for widespread application in small and medium-sized workshops. It also significantly improves the ease of operation and welding quality, thus possessing high practical value.
