Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of parts assembling and processing application, especially relates to a door plate for grid-connected cabinet and production device. BACKGROUND

[0002] In the design and manufacture of grid-connected cabinet, the door plate, as an important component, undertakes multiple key functions. In the normal operating state, when the door plate is in the closed position, it can effectively build a protective barrier to prevent external foreign objects from accidentally invading the interior of the grid-connected cabinet and avoid physical damage to the electrical equipment, line connections and various precision components therein, such as preventing components from loosening or falling off due to collision. At the same time, for grid-connected cabinets with strict protection level requirements, the door plate is one of the core elements to ensure that the overall protection performance meets the standards. It can effectively block the infiltration of small particles such as dust, moisture and water vapor, prevent line short circuits caused by dust accumulation or electrical faults caused by humid environments, and prevent mice, insects and other small animals from entering the interior of the grid-connected cabinet to avoid serious safety hazards caused by their gnawing on lines and damaging insulation layers, thereby ensuring that the electrical system inside the grid-connected cabinet can operate safely, stably and reliably.

[0003] In the production process of the door plate, it is usually composed of multiple components connected and combined through welding process. Due to the precise splicing and firm welding of multiple components, the components must be accurately pressed and stably fixed in position during welding operation to ensure the welding quality and the stability of the overall structure of the door plate. Therefore, there is an urgent need for an efficient production device specifically for the door plate of the grid-connected cabinet, which can quickly and accurately position each component of the door plate and achieve reliable fixation to facilitate welding work and meet the high-quality production requirements of the door plate of the grid-connected cabinet. SUMMARY

[0004] The utility model wants to solve the problem that provides a kind of door plate for grid-connected cabinet and production device, and door plate structure is stable and layout is reasonable, and production device can be quickly positioned to door plate structure, to facilitate welding work to carry out.

[0005] The technical scheme adopted by the utility model to solve the above problems is as follows: a door plate for grid-connected cabinet, comprising a panel, a welding frame is fixed in the middle of the panel, three power racks are arranged in the middle of the welding frame along the short side direction of the panel, the welding frame includes a first long side and a second long side located on both sides of the short side, and a first short side and a second short side located on both sides of the long side, a first corner portion is arranged at the end of the second long side facing the second short side, and a second corner portion is arranged at the end of the second short side facing the second long side, and the first corner portion and the second corner portion are welded and connected.

[0006] By firmly fixing the welding frame in the middle of the panel, a stable frame foundation is formed. The first long edge, the second long edge, the first short edge and the second short edge of the welding frame are connected to each other to form a closed rectangular structure, which can effectively disperse and withstand external forces. In particular, the first corner portion of the second long edge is welded to the second corner portion of the second short edge, and this connection mode forms a stable triangular structure at the corner of the welding frame. The triangular structure has stability and can greatly enhance the anti-deformation ability of the entire welding frame, thereby ensuring that the overall structure of the door panel can maintain its shape and integrity when subjected to external force impact, vibration or long-term use pressure, and is not prone to twisting, deformation or breakage.

[0007] A production device for producing the above-mentioned door panel for a grid-connected cabinet includes a base plate and a placement plane provided on the base plate. The panel is placed on the placement plane. The first long edge has first clamping blocks at both ends and in the middle for clamping the first long edge to the panel. The first corner portion has a second clamping block above for clamping the first corner portion to the panel. The second long edge has third clamping blocks at the other end and in the middle for clamping the other end and the middle to the panel. The first short edge has fourth clamping blocks above both ends for clamping both ends to the panel. The second corner portion has a fifth clamping block above for clamping the second corner portion to the panel. The second short edge has a sixth clamping block at the other end for clamping the second short edge to the panel. The three power supply racks have pressure plates above for clamping the three power supply racks to the panel by gravity.

[0008] The placement plane on the base plate provides a stable and horizontal base placement surface for the door panel. When the panel is placed on the placement plane, its position can be preliminarily determined, laying a foundation for the accurate positioning of subsequent components.

[0009] For the positioning of the welding frame, first clamping blocks are provided at both ends and in the middle of the first long edge. The first clamping blocks can apply uniform clamping force from above to the first long edge, making it tightly adhere to the panel and effectively limiting its displacement in the vertical and horizontal directions, ensuring the accuracy and stability of its position.

[0010] The second clamping block above the first corner portion, the third clamping block at the other end and in the middle of the second long edge, the fourth clamping block at both ends of the first short edge, the fifth clamping block above the second corner portion of the second short edge, and the sixth clamping block at the other end of the second short edge respectively clamp the edges and corners of the welding frame from the key positions. They work together to keep the shape of the welding frame complete and accurate, and whether it is a long edge or a short edge, it can be firmly fixed in all directions, eliminating the offset, rotation or deformation of the welding frame during welding, and achieving rapid and accurate positioning of the welding frame.

[0011] And for the three power supply frame, the upper setting of the pressing plate uses its self-weight to realize the positioning function. The pressing plate falls naturally by its own gravity, contacts with the power supply frame and applies downward pressure, tightly pressing the power supply frame to the panel, which ensures the stability of the power supply frame position without additional complex driving or adjusting device, simplifying the structure and improving the positioning speed and convenience.

[0012] Preferably, both sides of the pressing plate are provided with connecting parts, and the two connecting parts are provided with positioning pins. The upper end faces of the first long side and the second long side of the welding frame are provided with positioning holes, and the positioning pins are inserted and positioned in the positioning holes. The middle part of the pressing plate is provided with three groups of first positioning parts, and the lower end faces of the three groups of first positioning parts are respectively tightly attached to the upper end faces of the three power supply frames.

[0013] The positioning pins on the connecting parts of the two sides of the pressing plate cooperate with the positioning holes on the first long side and the second long side of the welding frame to realize the accurate positioning of the pressing plate in the horizontal direction. This positioning method can ensure that the pressing plate can be accurately positioned at the predetermined position every time it falls, so that the pressing force applied by the pressing plate to the power supply frame is uniform and stable, effectively avoiding the uneven force or displacement of the power supply frame caused by the deviation of the position of the pressing plate, thereby ensuring the position accuracy of the power supply frame during the welding process. The three groups of first positioning parts in the middle part of the pressing plate have their lower end faces tightly attached to the upper end faces of the three power supply frames, so that the power supply frames can be firmly fixed at the accurate positions on the panel. The cooperation of the positioning pins and the positioning holes and the attachment of the first positioning parts to the power supply frames make the entire positioning process relatively simple and efficient.

[0014] Preferably, the placement plane includes a first support below the first clamping block, a second support below the second clamping block, a third support below the third clamping block, a fourth support below the fourth clamping block, a fifth support below the fifth clamping block, and a sixth support below the sixth clamping block. The lower end faces of the first support, the second support, the third support, the fourth support, the fifth support, and the sixth support are fixed to the bottom plate, and the upper end faces are fixed with gaskets and pads from bottom to top. The upper end face of the pad abuts against the lower end face of the panel. The split structure can be quickly replaced and adjusted in height to achieve leveling.

[0015] Preferably, the first clamping block, the second clamping block, the third clamping block, the fourth clamping block, the fifth clamping block, and the sixth clamping block are respectively connected with a connecting block and a driving member. The driving member can generate a driving force to drive the connecting block connected thereto to move up and down in the vertical direction, thereby driving the first clamping block, the second clamping block, the third clamping block, the fourth clamping block, the fifth clamping block, or the sixth clamping block connected thereto to move up and down.

[0016] Preferably, the first support, the second support, the third support, the fourth support, the fifth support and the sixth support are provided with a first recess and a second recess, and the connecting block is provided with a first protrusion capable of being inserted into the first recess and a second protrusion capable of being inserted into the second recess. The mutual insertion of the first protrusion and the first recess and the second protrusion and the second recess provides a precise positioning reference for the connecting block relative to the supports. During the up-down movement of the clamping block, the connecting block can always run along the predetermined track, so that the position height of the clamping block is consistent and accurate when the clamping block is clamped or released.
