Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to a tooling for punching and repairing photovoltaic water tanks. Background Technology

[0002] The M-channel is a key component of a building-integrated photovoltaic (BIPV) system, primarily used for waterproofing, water drainage, and structural support of the photovoltaic brackets. For the structure of the M-channel, please refer to [link / reference needed]. Figure 1 The mounting holes on both sides of the M-shaped water tank are punched from the profile while it is in sheet metal form, such as... Figure 2 As shown, due to design errors, construction techniques, and material compatibility issues, the position of some mounting holes may deviate. If the deviation is small and not detected in time, it will proceed to the next process of bending to form the M-shaped water tank. The deviation in the mounting hole position will prevent installation and require rework before normal use.

[0003] Due to structural limitations of photovoltaic water tanks, there is no dedicated equipment for repair in related technologies. Reprocessing via a washing machine is costly; using an electric punching machine results in poor compatibility and cumbersome operation; and hydraulic processing requires custom-made molds, further increasing costs. Therefore, photovoltaic water tanks with misaligned holes are often scrapped, leading to waste. Utility Model Content

[0004] In view of this, the present invention provides a punching and repair tool for photovoltaic water tanks to solve the problems of high cost and complicated operation in repairing photovoltaic water tanks.

[0005] Firstly, this utility model provides a punching and repair fixture for photovoltaic water tanks, comprising:

[0006] Workbench;

[0007] A punching device is installed on the worktable;

[0008] An alignment device, mounted on the worktable, is adapted to position the workpiece for re-punching by the punching device.

[0009] Beneficial effects: The alignment device installed on the workbench can position and fix the reworkpiece at the processing station, and the punching device can re-punch the mounting holes with positional deviations. The photovoltaic water tank punching and repair fixture enables the batch repair of photovoltaic water tanks. Positioning and punching is convenient and quick, which can effectively control costs and avoid waste caused by the scrapping of photovoltaic water tanks.

[0010] In one alternative embodiment, the alignment device includes:

[0011] A positioning seat is provided, and the alignment device is fixed to the worktable via the positioning seat.

[0012] A flip plate is hinged to the positioning seat and can be flipped around the hinge axis to switch between a positioning state and a non-positioning state; a through groove is provided on the flip plate;

[0013] The positioning element is slidably disposed within the groove.

[0014] Beneficial effects: The flip plate hinged to the positioning seat can switch between the positioning state and the non-positioning state under the action of external force. When switching from the non-positioning state to the positioning state, the positioning part slides along the slide groove under the action of gravity and is embedded in the reference hole of the return workpiece to complete the positioning of the return workpiece. The alignment device has a simple structure and is easy to operate.

[0015] In one optional implementation, the positioning element includes:

[0016] A positioning block is disposed at the end of the positioning member, and the shape and size of the positioning block match the shape and size of the mounting hole on the workpiece.

[0017] Beneficial effects: By setting a positioning block at the end of the positioning component that matches the shape and size of the mounting hole on the rework piece, the positioning reliability is high, ensuring that the rework piece will not shift during punching and guaranteeing the quality of rework.

[0018] In one optional embodiment, the alignment device further includes:

[0019] Two limiting structures are spaced apart on the positioning member along the sliding direction of the positioning member.

[0020] Beneficial effects: By setting two limiting structures to limit the sliding range of the positioning component in the groove, the positioning component can be embedded into the reference hole at an appropriate depth after sliding down, which further ensures the reliability of positioning; moreover, the positioning component can slide, which is also convenient for manual adjustment.

[0021] In one alternative embodiment, the distance between the two limiting structures is greater than the thickness of the flip plate.

[0022] Beneficial effect: The distance between the two limiting structures must be greater than the thickness of the flip plate to ensure that the positioning component can slide within a certain range, thus facilitating positioning and adjustment.

[0023] In one alternative embodiment, the positioning seat is detachably mounted on the worktable.

[0024] Beneficial effects: The positioning seat can be detachably installed on the worktable, which can flexibly adapt to the needs of reworkpieces of different shapes and sizes; and by precisely constraining the position of the reworkpiece, it prevents slippage or displacement during punching; the modular design of the alignment device makes it easy to disassemble and replace worn parts, reducing maintenance costs, and the detachable connection method also facilitates subsequent tooling upgrades or functional expansion.

[0025] In one alternative embodiment, a retaining ring is provided at the connection between the hinge shaft and the positioning seat.

[0026] Beneficial effects: After the snap ring is installed, the radial pressure generated by the snap ring's own elastic deformation constrains the axial displacement of the hinge shaft on the positioning seat, preventing the hinge shaft from separating from the positioning seat due to vibration or load changes; the snap ring has both fixing and buffering functions in the connection between the hinge shaft and the positioning seat.

[0027] In one alternative implementation, the flip plate is provided with a handle.

[0028] Beneficial effect: The handle makes it easier to manually rotate the flip plate, improving the ease of operation.

[0029] In one alternative embodiment, the punching device is detachably mounted on the worktable.

[0030] Beneficial effects: The punching device is detachably mounted on the workbench. It can be used not only as a punching device for rework but also, when rework is not required, it can be removed and used directly for machining holes. One set of punching devices can be used in different processes, without any idle waste.

[0031] In one optional implementation, the number of alignment devices is two sets, and the distances from the two sets of alignment devices to the rework station of the workpiece are different.

[0032] Beneficial effects: During rework, two sets of alignment devices are used to position the front (first side) and back (second side) of the photovoltaic water tank respectively, eliminating the need to disassemble and adjust the position of the alignment fixture, thus improving the positioning and processing efficiency.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0053] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0055] In related technologies, if the size or position of the mounting holes 41 on the photovoltaic water tank is deviated, the photovoltaic water tank cannot be installed and used normally. Hole position deviations can cause conflicts between the photovoltaic water tank and the purlin or column installation positions. For example, if... Figure 1 When the distance between the center of the M-shaped water tank and the center of the column is less than 155mm, mechanical interference will occur during installation, requiring readjustment of the hole positions. However, due to the limitations of the photovoltaic water tank's shape, there is no suitable repair equipment in related technologies, resulting in high repair costs, while direct scrapping would be wasteful. Therefore, this utility model is proposed.

[0056] The following is combined with Figures 3 to 9 The following describes embodiments of the present invention.

[0057] According to an embodiment of the present invention, in one aspect, a photovoltaic water tank punching and repair tooling is provided, comprising:

[0058] Workbench 3;

[0059] Punching device 1 is installed on the workbench 3;

[0060] Alignment device 5, installed on the worktable 3, is adapted to position the return workpiece 4 so that the punching device 1 can re-punch.

[0061] The alignment device 5 installed on the workbench 3 can position and fix the reworkpiece 4 at the processing station, and the punching device 1 can re-punch the mounting holes 41 that are misaligned. The photovoltaic water tank punching and rework fixture realizes the batch rework of photovoltaic water tanks. The positioning punching is convenient and quick, which can effectively control costs and avoid waste caused by the scrapping of photovoltaic water tanks.

[0062] In some embodiments, the alignment device 5 includes:

[0063] Positioning seat 14, the alignment device 5 is fixed to the worktable 3 through the positioning seat 14;

[0064] The flip plate 9 is hinged to the positioning seat 14 and can be flipped around the hinge axis 8 to switch between the positioning state and the non-positioning state; the flip plate 9 is provided with a through groove 91.

[0065] The positioning element 6 is slidably disposed within the slide groove 91.

[0066] The flip plate 9, which is hinged to the positioning seat 14, can switch between the positioning state and the non-positioning state under the action of external force. When switching from the non-positioning state to the positioning state, the positioning part 6 slides along the slide groove 91 under the action of gravity and is embedded in the reference hole of the return workpiece 4 to complete the positioning of the return workpiece 4. The alignment device 5 has a simple structure and is easy to operate.

[0067] It should be noted that only a few holes on the rework piece 4 will typically be misaligned. In this case, the non-misaligned mounting holes 41 can serve as the reference holes for positioning, and the positioning element 6 is embedded in the reference holes to achieve positioning. If all mounting holes 41 are misaligned, it is only necessary to drill a reference hole on the rework piece 4 first. The distance between the alignment device 5 and the processing station of the rework piece 4 should be adapted to the location of the reference hole, so that after the positioning seat 14 is installed, the positioning element 6 can be precisely embedded in the reference hole after it is rotated and slid with the flipping plate 9.

[0068] In some embodiments, the positioning element 6 includes:

[0069] A positioning block 61 is disposed at the end of the positioning member 6, and the shape and size of the positioning block 61 match the shape and size of the mounting hole 41 on the return workpiece 4.

[0070] A positioning block 61 is provided at the end of the positioning component 6, which matches the shape and size of the mounting hole 41 on the rework piece 4. The positioning reliability is high, so that the rework piece 4 will not shift during punching, thus ensuring the quality of rework.

[0071] In some embodiments, the alignment device 5 further includes:

[0072] Two limiting structures 13 are spaced apart on the positioning member 6 along the sliding direction of the positioning member 6.

[0073] Two limiting structures 13 are set to limit the sliding range of the positioning member 6 in the slide groove 91, which can make the positioning member 6 sink to a suitable depth after sliding down into the reference hole, further ensuring the reliability of positioning; moreover, the positioning member 6 can slide, which is also convenient for manual adjustment.

[0074] In some embodiments, the distance between the two limiting structures 13 is greater than the thickness of the flip plate 9.

[0075] The distance between the two limiting structures 13 must be greater than the thickness of the flip plate 9 to ensure that the positioning component 6 can slide within a certain range, thus facilitating positioning and adjustment.

[0076] Specifically, such as Figure 5 As shown, the limiting structure 13 includes limiting screws. Multiple spaced screw holes can also be provided on the positioning member 6 along its length, allowing adjustment of the distance and height between the two limiting screws to accommodate photovoltaic water tanks of various structural shapes. Of course, in some embodiments, limiting blocks or similar structures can also be used.

[0077] In some embodiments, the positioning seat 14 is detachably mounted on the worktable 3.

[0078] The positioning seat 14 can be detachably installed on the worktable 3, which can flexibly adapt to the needs of return workpieces 4 of different shapes and sizes; and by precisely constraining the position of the return workpiece 4, it prevents slippage or displacement during the punching process; the alignment device 5 adopts a modular design to facilitate the disassembly and replacement of worn parts, reduce maintenance costs, and the detachable connection method also facilitates subsequent tooling upgrades or functional expansion.

[0079] In some embodiments, a retaining ring 10 is provided at the connection between the hinge shaft 8 and the positioning seat 14.

[0080] After the snap ring 10 is installed, the radial pressure generated by the elastic deformation of the snap ring 10 itself constrains the axial displacement of the hinge shaft 8 on the positioning seat 14, preventing the hinge shaft 8 from separating from the positioning seat 14 due to vibration or load changes; the snap ring 10 has both fixing and buffering functions in the connection between the hinge shaft 8 and the positioning seat 14.

[0081] In some embodiments, the flip plate 9 is provided with a handle 7.

[0082] The handle 7 allows for easy manual operation of the rotating plate 9, improving ease of use.

[0083] In some embodiments, the punching device 1 is detachably mounted on the worktable 3.

[0084] The punching device 1 is detachably installed on the workbench 3. It can be used not only as a punching device for rework but also as a processing device for mounting holes 41 when rework is not required. One set of punching device 1 can be used in different processes without being idle or wasted.

[0085] In some embodiments, the number of alignment devices 5 is two sets, and the distances from the two sets of alignment devices 5 to the rework station of the workpiece 4 are not the same.

[0086] During rework, two sets of alignment devices 5 are used to position the front (first side) and back (second side) of the photovoltaic water tank respectively, eliminating the need to disassemble and adjust the alignment fixture, thus improving positioning processing efficiency. Since punching holes in the sheet material is done in pairs (left and right), a positional deviation in one will inevitably lead to a positional deviation in the other. This results in different distances from the edge to the two corresponding mounting holes 41 at the offset positions after the M-shaped water tank is formed. Figure 2 (a1≠a2). Therefore, two sets of alignment devices 5 are set up, and the distances from the two sets of alignment devices 5 to the rework station of the workpiece 4 are different. The two sets of alignment devices 5 are respectively adapted to the reference hole positions of the misaligned mounting holes 41 on the M water tank. During rework, it is not necessary to adjust the position of the alignment devices 5. The first set of alignment devices 5 is used for alignment and positioning. After the first side of the workpiece 4 is reworked, the workpiece 4 is directly flipped over, and the second set of alignment devices 5 is used for the second side alignment to complete the punching rework, thereby improving the efficiency of the rework.

[0087] like Figures 3-9 As shown, this embodiment of the invention provides a punching and repair fixture for a photovoltaic M-shaped water tank. The fixture consists of a punching device 1 and two sets of alignment devices 5. A lifting ring 2 is installed at each of the four corners of the workbench 3 for easy on-site hoisting. The punching device 1 is mounted on the workbench 3 via mounting blocks 15. Specifically, the mounting blocks 15 are fixedly locked to the workbench 3 by locking screws 12. The punching device 1 is fixed to the mounting blocks 15 by four mounting screws 16 for easy repair.

[0088] The punching device 1 is installed in the middle of the workbench 3. An alignment device 5 is installed on each of the left and right sides of the punching device 1. This is to facilitate use and improve rework efficiency. When installing the alignment device 5, the two positioning pins 11 are used to accurately position the alignment device 5, and then it is fixed and locked with screws.

[0089] The alignment device 5 includes a positioning base 14, a flip plate 9, and a positioning element 6. The flip plate 9 is rotatably connected to the positioning base 14 via a hinge shaft 8, and one end of the hinge shaft 8 is engaged with a retaining spring 10 to prevent the hinge shaft 8 from falling out. A handle 7 is locked onto the flip plate 9 with screws for easy flipping operation. A groove 91 is provided at the front end of the flip plate 9, and the positioning element 6 is slidably installed in the groove 91 to achieve the positioning function. Two limit screws are installed at intervals on the positioning element 6 to accurately control the vertical movement distance of the positioning element 6.

[0090] This utility model's photovoltaic water tank punching and repair fixture solves the problem of uneven rework hole positions through the alignment device 5, and also improves repair efficiency. Furthermore, by simultaneously arranging two sets of alignment devices 5, alignment operations on both sides can be achieved, reducing processing costs while increasing processing efficiency.

[0091] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
