[0025] Currently, the processing and production of kitchen knives requires pre-welding of the steel. To ensure weld quality, this process places high demands on the relative positioning of the various materials. Laser welding requires full welding of the steel sheet, which requires the materials to remain in the same plane. Furthermore, the processing of kitchen knives often requires the handling of irregularly shaped materials, such as those with varying sizes, thicknesses, and surface flatness.

[0026] However, in current production, conventional fixtures often cannot meet the needs of multi-angle operations, have low clamping accuracy, large gaps between plate joints, and misaligned material positions, which greatly affect process efficiency and welding quality.

[0027] The overall structure, working principle and technical effects of the welding fixture system provided by the present invention are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0028] Please refer to Figure 1-Figure 3 The present invention provides a welding fixture system for use in the field of welding technology. Specifically, the welding fixture system in the present invention is used for tool production. In other optional embodiments, the welding fixture system provided by the present invention can also be used for welding processing of other sheet materials.

[0029] Please refer to Figure 1 and Figure 2The welding fixture system provided by the present invention includes a fixed table 100, a mobile mechanism 200, a first rotary mechanism 300, a second rotary mechanism 400, and a fixture gripper 500. The fixed table 100 is arranged horizontally and supported by a table bracket. The mobile mechanism 200 is movably arranged on the fixed table 100, the first rotary mechanism 300 is arranged on the mobile mechanism 200, the second rotary mechanism 400 is arranged on the first rotary mechanism 300, and the fixture gripper 500 is arranged on the second rotary mechanism 400. The mobile mechanism 200 is used to drive the first rotary mechanism 300 to move on the fixed table 100, the first rotary mechanism 300 is used to drive the second rotary mechanism 400 to rotate in the horizontal direction, and the second rotary mechanism 400 is used to drive the fixture gripper 500 to rotate in the vertical direction.

[0030] The clamp gripper 500 is used to clamp the material to be welded, and then the moving mechanism 200, the first rotating mechanism 300 and the second rotating mechanism 400 are set to drive the clamp gripper 500 to move in multiple directions, thereby accurately adjusting the angle of the material to be welded to meet the multi-angle operation requirements during welding, thereby improving the current problems of low clamping accuracy, large plate seam joint gap, and material misalignment, and improving process efficiency and welding quality.

[0031] Please refer to Figure 1 and Figure 2 In some optional embodiments, the moving mechanism 200 includes a panel 210, a panel rail 220, and a panel bracket 230. A receiving slot 110 for accommodating the panel 210 is provided on the fixed table 100. The receiving slot 110 extends through one side of the fixed table 100, facilitating movement of the panel 210 outside the fixed table 100. The panel rails 220 are disposed below the fixed table 100 and on both sides of the receiving slot 110. Specifically, the panel rails 220 are welded to the fixed table 100 via right-angle brackets. The panel bracket 230 is slidably disposed between the two panel rails 220. The panel 210 is disposed on the top surface of the panel bracket 230, and the upper surface of the panel 210 is flush with the surface of the fixed table 100. In this embodiment, to reduce the weight of the overall structure, the panel bracket 230 is lightweight while still meeting the required support requirements. Specifically, the side of the panel bracket 230 is hollowed out. The first rotating mechanism 300 is set on the panel 210. When it is necessary to drive the material to be welded to move in the horizontal direction, the panel 210 is moved along the guide rail direction of the panel 210, thereby driving the first rotating mechanism 300 and the material to be welded thereon to move in the horizontal direction, thereby achieving the effect of facilitating the movement of the welding material in the horizontal direction.

[0032] It can be understood that the setting of the mobile mechanism 200 can also allow workers to pull out the panel 210 and fix the material through the clamp gripper 500 before operating the welding equipment in actual production, and then return the panel 210 to its position and then operate the welding equipment to facilitate loading and unloading.

[0033] Please refer to Figure 2 In some optional embodiments, the first rotary mechanism 300 includes a mounting platform 310, a circular track 320, and a rotating member. The mounting platform 310 is disposed on the mobile mechanism 200. Specifically, the mounting platform 310 is fixedly connected to the panel 210. The rotating member (not shown in the drawings) is embedded in the mounting platform 310 and connected to the second rotary mechanism 400. The circular track 320 is disposed on the mounting platform 310 and is adapted to the second rotary mechanism 400. The rotating member can be a driving device such as an electric motor, which can drive the second rotary mechanism 400 to move along the circular track 320, thereby achieving the effect of driving the second rotary mechanism 400 to rotate in the horizontal direction.

[0034] Among them, in this embodiment, two second rotating mechanisms 400 are provided on the mounting table 310, and the two second rotating mechanisms 400 are independently controlled by the first rotating mechanism 300, so that the two second rotating mechanisms 400 can be driven to rotate separately by the first rotating mechanism 300 to adjust the angle between the two second rotating mechanisms 400, thereby realizing the same-side clamping and opposite-side clamping of the material to be welded. When the angle between the two second rotating mechanisms 400 is 90°, the clamp grippers 500 on the two second rotating mechanisms 400 can respectively clamp the adjacent edges of the material to be welded, so that the clamp system can fix materials with a certain volume that exceeds the fixed table 100, thereby improving the versatility of the clamp system.

[0035] For further information, please refer to 1- Figure 3 In some optional embodiments, the second rotary mechanism 400 includes a rotary arm support 410 and a rotary arm 420. Two rotary arm supports 410 are disposed opposite each other on the first rotary mechanism 300. Specifically, the two rotary arm supports 410 are mounted on the mounting platform 310 and are adapted to the circular track 320. Both rotary arm supports 410 are movable along the circular track 320. The rotary arm 420 is rotatably mounted at the end of the rotary arm support 410. The rotary arms 420 on the two rotary arm supports 410 are disposed opposite each other, and the clamp gripper 500 is disposed on the rotary arm 420. In this embodiment, the rotary arm 420 is C-shaped. The two clamp grippers 500 are disposed at each end of the rotary arm 420 and are disposed opposite each other in the vertical direction. The two opposing clamp grippers 500 can clamp the material to be welded. The rotary arm 420 is rotatably mounted on the rotary arm support 410. The rotary arm 420 is driven to rotate on the rotary arm support 410, thereby driving the clamp gripper 500 to rotate.

[0036] Please refer to Figure 1-Figure 3 In some optional embodiments, a support shaft 430 is connected between the rotary arm bracket 410 and the rotary arm 420, and the rotary arm 420 is rotatably connected to the rotary arm bracket 410 via the support shaft 430. A drive motor 440 is provided in the rotary arm bracket 410, and the drive motor 440 is coaxially connected to the support shaft 430. The support shaft 430 is driven to rotate by the drive motor 440, thereby driving the rotary arm 420. Furthermore, the second rotary mechanism 400 also includes a clamp rotary layer 450 and a rotary slide (not shown in the drawings). The clamp rotary layer 450 is also C-shaped, and the rotary slide is fitted on the inner side of the rotary arm 420. The clamp rotary layer 450 is provided on the inner side of the rotary arm 420 via the rotary slide, and the clamp gripper 500 is provided on the clamp rotary layer 450. This makes it easy to set the clamp gripper 500 on the clamp rotation layer 450. At the same time, the clamp rotation layer 450 can also move independently relative to the rotary arm 420, and cooperate with the independent movement of the rotary arm bracket 410 and the rotary arm 420 to achieve multi-angle welding operations of the materials to be welded.

[0037] Please refer to Figure 1-Figure 3 In some optional embodiments, the clamp gripper 500 includes a sub-cylinder 510, a sub-cylinder 520, and a gripper cylinder 530. The sub-cylinder 510 is disposed on the second rotary mechanism 400. Specifically, the sub-cylinder 510 is disposed on the clamp rotary layer 450, and a plurality of sub-cylinders 520 are evenly distributed on the sub-cylinder 510. The gripper cylinder 530 is slidably disposed within the sub-cylinder 520 along the length direction of the sub-cylinder 520. The clamp grippers 500 are disposed opposite each other in pairs, with the sub-cylinders 510 disposed at both ends of the clamp rotary layer 450. The two sub-cylinders 510 on the same clamp rotary layer 450 are disposed opposite each other, and the sub-cylinders 520 are located on opposite sides of the two sub-cylinders 510. The gripper cylinders 530 on the two opposing clamp grippers 500 correspond one to one.

[0038] Since the diameter of a single gripper cylinder 530 is small and the cylinders on the sub-cylinder 510 are arranged closely, it is possible to ensure that there are enough force application points when clamping materials of different volumes; since the internal pressure of each gripper cylinder 530 is equal, it is possible to ensure that any shape can be uniformly stressed in any three-dimensional direction when being grasped by the gripper cylinder 530, which makes the clamping system stable and precise in clamping, and enhances the versatility of this system in handling special-shaped materials.

[0039] Furthermore, to enhance the gripping effect of the gripper cylinder 530 on the material, a pressure detector (not shown) is provided within the sub-cylinder 510. This detector is used to detect the pressure applied by the gripper cylinder 530 to the material to be welded. This ensures uniform force on the material and enhances gripping.

[0040] Please refer to Figure 1-Figure 3In some optional embodiments, in order to facilitate the clamping of the material to be welded, a telescopic cylinder 600 is further provided between the second rotary mechanism 400 and the sub-cylinder 510. The telescopic cylinder 600 is used to drive the two opposing sub-cylinders 510 to move closer to or further away from each other, thereby achieving a clamping effect on the material to be welded. Furthermore, the telescopic cylinder 600 has an outer tube 610 and an inner tube 620. One end of the inner tube 620 is connected to the sub-cylinder 510, and the other end of the inner tube 620 is connected to an external gas supply device. The outer tube 610 is connected to the external gas supply device. The sub-cylinder 510 is supplied with gas through the inner tube 620 to achieve a clamping effect on the material to be welded; the telescopic cylinder 600 is extended and retracted through the outer tube 610 to drive the two sub-cylinders 510 to move closer to or further away from each other, thereby being suitable for materials to be welded of different thicknesses.

[0041] Furthermore, in other optional embodiments, communication equipment and controllers can be connected between the mobile mechanism 200, the first rotating member mechanism, the second rotating mechanism 400 and the clamp gripper 500 to achieve remote operation of each component and reduce close-range operation of personnel.

[0042] To sum up, the implementation principle of the welding fixture system provided by the present invention is: using the fixture gripper 500 to clamp the material to be welded, and then by setting the moving mechanism 200, the first rotating mechanism 300 and the second rotating mechanism 400, the fixture gripper 500 is driven to move in multiple directions, and then the angle of the material to be welded is accurately adjusted to meet the multi-angle operation requirements during welding, thereby improving the current problems of low clamping accuracy, large plate seam joint gap, and material misalignment, and improving process efficiency and welding quality.

[0043] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
