Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a fixture for welding sheet metal cabinets, and more particularly to a special fixture that can achieve precise positioning, stable clamping, and flexible adjustment of the welding position of sheet metal. Background Technology

[0002] In the manufacturing process of server racks, the welding quality of sheet metal parts directly affects the overall structural strength and appearance of the rack. Currently, sheet metal welding of server racks typically uses conventional fixtures for fixing, but these fixtures have limitations in structural design and function, making it difficult to meet the demands for efficient and high-precision welding.

[0003] Specifically, the existing technology has the following main problems and drawbacks: 1. Insufficient positioning accuracy and inflexible welding position adjustment: Existing fixtures often lack precise movement paths and guiding mechanisms, making it difficult to achieve flexible adjustments to multiple positions and angles during sheet metal welding. This results in welding tools being unable to accurately align with the welding points, affecting welding accuracy, especially in applications requiring omnidirectional welding, where existing fixtures are inadequate.

[0004] 2. Poor clamping stability, easily leading to sheet metal deformation or displacement: Existing clamping devices mostly use a single-direction clamping method, which cannot effectively fix the edges and bottom surfaces of the sheet metal simultaneously. During the welding process, the sheet metal is prone to shaking, deformation, or displacement due to gravity or external welding forces, which not only reduces welding quality but may also increase the product scrap rate. Utility Model Content

[0005] In order to overcome the problems of inflexible adjustment of sheet metal welding position and unstable clamping that easily leads to deformation and displacement in the existing technology, this utility model provides a cabinet sheet metal welding fixture. By setting a movable frame and multiple sets of pneumatic clamping components, and cooperating with the rack movement path, the sheet metal welding position can be accurately adjusted and stably fixed.

[0009] The aforementioned cabinet sheet metal welding fixture has four clamping components, including a first clamping component, a second clamping component, a third clamping component, and a fourth clamping component; wherein, the first clamping component and the second clamping component are used to fix the sheet metal placed on the front, and the third clamping component and the fourth clamping component are used to fix the sheet metal placed on the back.

[0010] The aforementioned cabinet sheet metal welding fixture includes a first clamping component and a third clamping component for clamping and fixing the edges of the sheet metal and connectors; and a second clamping component and a fourth clamping component for clamping and fixing the bottom surface of the sheet metal and connectors.

[0024] This embodiment provides a cabinet sheet metal welding fixture, such as Figure 1-5As shown, its overall structure mainly includes a support frame 1, a movable frame 2, a clamping component 4 for holding sheet metal, and a driving component 5 for moving the frame 2. All parts work together to achieve precise positioning and stable fixation of the cabinet sheet metal during the welding process, meeting the needs of different welding positions and welding methods. The frame 1 serves as the supporting base of the entire fixture, and its upper part is planned with a moving path for the sheet metal to move horizontally in coordination with welding operations. The design of this moving path fully considers the requirement for the sheet metal to flexibly adjust its position during the welding process to complete all-round welding, providing accurate guidance for the subsequent movement of the frame 2 and the positioning of the sheet metal.

[0025] The frame 2 is horizontally arranged on the upper part of the frame 1 and can move along the moving path. The upper part of the frame 2 has a platform 3 arranged at intervals and symmetrically at both ends along the length direction. The platform 3 provides a stable support platform for the subsequent installation of the clamping component 4. The frame 2 is connected to the drive component 5 and can reciprocate along the moving path under the action of the drive component 5, thereby driving the sheet metal installed on the frame 2 to move, which facilitates the welding tools to perform welding operations on the sheet metal and connecting parts at different points.

[0026] In this embodiment, there are four clamping components 4: a first clamping component 4, a second clamping component 4, a third clamping component 4, and a fourth clamping component 4. Each clamping component 4 includes a cylinder seat 41, a first cylinder 42, a pressure arm 43, a support frame 44, and a pad 45. The specific structure and operation are as follows: The cylinder seat 41 is installed on one side of the upper part of the platform 3 and is firmly connected by bolts. The bolt connection method is not only convenient for installation, but also ensures the connection strength and stability between the cylinder seat 41 and the platform 3, providing a reliable foundation for the subsequent installation of the first cylinder 42 and the pressure arm 43. The first cylinder 42 is installed on one side of the cylinder seat 41 and is installed by a hinged connection. The hinged connection allows the first cylinder 42 to rotate flexibly within a certain angle range, thereby better adapting to the movement requirements of the pressure arm 43 and achieving precise clamping action. The pressure arm 43 is mounted on the top of the cylinder seat 41 and is hinged to the cylinder rod end of the first cylinder 42. When the first cylinder 42 extends or retracts, the cylinder rod will push or pull the pressure arm 43 to rotate around the cylinder seat 41. For example, when the cylinder rod of the first cylinder 42 extends, the pressure arm 43 will rotate downward around the cylinder seat 41, thereby clamping the sheet metal placed on the support 44; when the cylinder rod of the first cylinder 42 retracts, the pressure arm 43 will rotate upward around the cylinder seat 41, releasing the clamping of the sheet metal.

[0027] The support frame 44 is installed on the upper part of the frame 3 and is bolted on. The support frame 44 is used to support the edge of the sheet metal. The design of the support frame 44 is customized according to the shape and size of the sheet metal, which can ensure that the edge of the sheet metal is stably supported when placed, and avoid deformation due to gravity or other external forces during the welding process. The pad 45 is set at the end of the pressure arm 43 that contacts the sheet metal. The flexible pad 45 can play a buffering role, reduce the pressure of the pressure arm 43 on the edge of the sheet metal, effectively reduce the deformation of the edge of the sheet metal during the clamping process, and ensure the welding quality of the sheet metal.

[0028] The four clamping components 4 have clearly defined functions. The first and second clamping components 4 are used to fix the sheet metal and its connectors placed on the front during welding. The third and fourth clamping components 4 are used to fix the sheet metal and its connectors placed on the back during welding. The first and third clamping components 4 are mainly used to clamp and fix the edges of the sheet metal and connectors. Through the cooperation of the pressure arm 43 and the support frame 44, pressure is applied to the edges of the sheet metal from both the top and bottom to ensure that the edges of the sheet metal remain stable during welding. The second and fourth clamping components 4 are used to clamp and fix the bottom surface of the sheet metal and connectors. By applying pressure to the bottom surface of the sheet metal, the sheet metal is prevented from shaking or shifting during welding, thus facilitating all-round welding and fixing between the sheet metal and the connectors.

[0029] The drive assembly 5 includes a second cylinder 51, a slider 52, and a slide rail 53. Its specific structure and operation are as follows: The slide rail 53 is installed on the upper part of the frame 1, with slide rails 53 spaced apart along the moving path. The precision and surface quality of the slide rail 53 play a crucial role in the smooth movement of the frame 2. Therefore, high-precision slide rails 53 are selected, and their installation position is ensured to guarantee that the frame 2 can move smoothly along the moving path. The slider 52 is installed at the bottom of the frame 2, and sliders 52 adapted to the slide rails 53 are provided. The fitting precision between the slider 52 and the slide rail 53 directly affects the frame 2's stability. To improve the moving accuracy of frame 2, the slider 52 is manufactured using high-precision machining technology, and the gap between slider 52 and slide rail 53 is made reasonable to reduce frictional resistance and improve moving efficiency. The second cylinder 51 is installed on the upper part of frame 1 and arranged along the moving path. The cylinder body of the second cylinder 51 is fixedly connected to frame 1 by bolts, and the cylinder rod of the second cylinder 51 is fixedly connected to frame 2 by bolts. This connection method can ensure that the connection between the second cylinder 51 and frame 1 and frame 2 is firm and reliable during operation, and there will be no loosening or falling off.

[0030] When the cylinder rod of the second cylinder 51 extends, it pushes the frame 2 to move in one direction along the slide rail 53; when the cylinder rod of the second cylinder 51 retracts, it pulls the frame 2 to move in the opposite direction along the slide rail 53. By controlling the extension and retraction of the second cylinder 51, the frame 2 can be precisely driven to reciprocate along the moving path, which facilitates spot welding operations between sheet metal and connecting parts in conjunction with welding tools. For example, when spot welding, the position of the frame 2 can be adjusted by the second cylinder 51 according to the position requirements of the welding point, so that the welding point on the sheet metal is accurately aligned with the welding tool, thereby improving the welding accuracy and efficiency.

[0031] The cabinet sheet metal welding fixture of this embodiment achieves precise positioning and stable fixation of the cabinet sheet metal during the welding process through the coordinated work of the above-mentioned parts. It can meet the needs of different welding positions and welding methods, and effectively improve welding quality and production efficiency.
