Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and particularly relates to a repair tool for punching holes in a photovoltaic water tank. Background Art

[0002] The M water tank is a key component in a building-integrated photovoltaic system, mainly used for waterproofing, water guiding and structural support of photovoltaic brackets. For the structure of the M water tank, see Figure 1 . The installation holes on both sides of the M water tank are punched when the profile is in the form of a sheet. As Figure 2 shown, due to problems such as design errors, construction techniques and material compatibility, the positions of individual installation holes may deviate. In the case of a small deviation, if it is not detected in time, it will enter the next process of bending to form the M water tank. The deviation of the installation hole position will cause it to be impossible to install, and it needs to be repaired before it can be used normally.

[0003] Due to the structural limitations of the photovoltaic water tank, there is no special repair equipment in the related art. For example, reprocessing through a milling machine has a high cost; if an electric punching machine is used, the matching is poor and the operation is troublesome; if hydraulic processing is used, a mold needs to be customized again, and the cost will also increase. Therefore, photovoltaic water tanks with hole position deviations often end up being scrapped directly, resulting in waste. Summary of the Invention

[0052] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0053] In the description of the invention, it should be noted that unless otherwise specified, the meaning of "a plurality of" is two or more; the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention. In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0054] In the description of the present invention, it should also be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] In the related art, if there are deviations in the size or position of the mounting holes 41 on the photovoltaic water tank, the photovoltaic water tank cannot be normally installed and used. The hole position deviation will cause conflicts in the installation positions of the photovoltaic water tank and the purlin or column. For example, when the distance between the center of the M-shaped water tank and the center of the column shown in Figure 1 is less than 155 mm, mechanical interference will occur during installation, and the hole position needs to be readjusted. Due to the shape limitation of the photovoltaic water tank, there is no suitable repair equipment in the related art, the repair cost is high, and direct scrapping will cause waste. In view of this, the present invention is proposed.

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

[0057] According to an embodiment of the present invention, on the one hand, a punching repair tooling for a photovoltaic water tank is provided, including:

[0058] A workbench 3;

[0059] A punching device 1, installed on the workbench 3;

[0060] An alignment device 5, installed on the workbench 3, adapted to position the workpiece to be repaired 4 so that the punching device 1 can punch holes again.

[0061] The alignment device 5 installed on the workbench 3 can position and fix the returned workpiece 4 at the processing station, and re-punch the mounting hole 41 with a deviation in position through the punching device 1. The punching and repair tooling for the photovoltaic water tank realizes the batch repair of the photovoltaic water tank, is convenient and fast for positioning and punching, can effectively control the cost, and avoid the waste caused by scrapping the photovoltaic water tank.

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

[0063] A positioning seat 14, and the alignment device 5 is fixed to the workbench 3 through the positioning seat 14;

[0064] A turning plate 9, hinged to the positioning seat 14 and capable of turning around the hinge shaft 8 to switch between a positioning state and a non-positioning state; a through chute 91 is formed on the turning plate 9;

[0065] A positioning member 6, slidably disposed in the chute 91.

[0066] The turning plate 9 hinged to the positioning seat 14 can be switched between a positioning state and a non-positioning state under an external force. During the process of switching from the non-positioning state to the positioning state, the positioning member 6 slides along the chute 91 under the action of gravity and is embedded into the reference hole of the returned workpiece 4 to complete the positioning of the returned workpiece 4. The alignment device 5 has a simple structure and is easy to operate.

[0067] It should be noted that generally only a small number of holes on the returned workpiece 4 will be misaligned. At this time, the non-misaligned mounting holes 41 can be used as reference holes for positioning, and the positioning member 6 is embedded into the reference holes to achieve positioning; if all the mounting holes 41 are misaligned, only need to drill a reference hole on the returned workpiece 4 first. The distance between the alignment device 5 and the processing station of the returned workpiece 4 is adapted to the position of the reference hole. It is necessary to ensure that after the positioning seat 14 is installed, the positioning member 6 can just be embedded into the reference hole after turning and sliding with the turning plate 9.

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

[0069] A positioning block 61, 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 returned workpiece 4.

[0070] By providing a positioning block 61 at the end of the positioning member 6 that matches the shape and size of the mounting hole 41 on the returned workpiece 4, the positioning reliability is high, so that the returned workpiece 4 will not shift during punching, ensuring the repair quality.

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

[0072] Two limiting structures 13, spaced along the sliding direction of the positioning member 6 and disposed on the positioning member 6.

[0073] Two limiting structures 13 are provided to limit the sliding range of the positioning member 6 in the sliding groove 91, enabling the depth of the positioning member 6 embedded in the reference hole after sliding and falling to be appropriate, further ensuring the reliability of positioning; moreover, the positioning member 6 is slidable, which is also convenient for manual adjustment.

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

[0075] The distance between the two limiting structures 13 being greater than the plate thickness of the flipping plate 9 can ensure that the positioning member 6 can slide within a certain range, thereby facilitating positioning and adjustment.

[0076] Specifically, as Figure 5 shown, the limiting structure 13 includes a limiting screw. Multiple spaced screw holes can also be provided along the length direction of the positioning member 6, and the distance and height of the two limiting screws can be adjusted as needed to adapt to photovoltaic water troughs of various structural shapes. Of course, in some embodiments, structures such as limiting blocks can also be used.

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

[0078] Detachably mounting the positioning seat 14 on the workbench 3 can flexibly adapt to the requirements of workpieces 4 of different shapes and sizes; moreover, by precisely restricting the position of the workpiece 4, sliding or offset during the punching process can be prevented; the alignment device 5 adopts a modular design, which is convenient for disassembling and replacing worn parts, reducing maintenance costs, and the detachable connection method is also convenient for subsequent tooling upgrade or function expansion.

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

[0080] After installing the circlip 10, the radial pressure generated by the self-elastic deformation of the circlip 10 restricts the axial displacement of the hinge shaft 8 on the positioning seat 14, preventing the hinge shaft 8 from detaching from the positioning seat 14 due to vibration or load changes; the circlip 10 has both a fixing and a buffering function in the connection between the hinge shaft 8 and the positioning seat 14.

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

[0082] Providing the handle 7 can facilitate manual operation to rotate the flipping plate 9 and improve the operation convenience.

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

[0084] The punching device 1 is installed on the workbench 3 in a detachable manner. It can not only be used as the punching device 1 for the repair tooling, but also, when repair is not required, the punching device 1 can be removed and directly used for the processing device of the installation hole 41. One set of punching device 1 can be applied to different processes without idle waste.

[0085] In some embodiments, the number of the alignment devices 5 is two sets, and the distances from the two sets of alignment devices 5 to the repair station of the workpiece to be repaired 4 are different.

[0086] During repair, two sets of alignment devices 5 are used to position the front side (the first side) and the back side (the second side) of the photovoltaic water trough respectively, without the need to disassemble and adjust the position of the alignment tooling, thus improving the positioning and processing efficiency. Since the punching is carried out in groups of two on the left and right when punching in the form of a plate, if one has a position deviation, the other will surely have a position deviation. This results in different distances from the two corresponding installation holes 41 with offset positions to the edge after forming the M-shaped water trough ( Figure 2 where a1 ≠ a2). Therefore, two sets of alignment devices 5 are provided, and the distances from the two sets of alignment devices 5 to the repair station of the workpiece to be repaired 4 are different. The two sets of alignment devices 5 respectively correspond to the reference hole positions of the misaligned installation holes 41 on the M-shaped water trough. During repair, there is no need to adjust the position of the alignment device 5. Use the first set of alignment device 5 for alignment and positioning. After completing the repair of the first side of the workpiece to be repaired 4, directly turn over the workpiece to be repaired 4, and use the second set of alignment device 5 for alignment of the second side to complete the punching repair, thereby improving the repair work efficiency.

[0087] As Figures 3 - 9 shown, the embodiment of the present invention provides a punching repair tooling for a photovoltaic M-shaped water trough. The tooling is composed 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 convenient on-site hoisting. The punching device 1 is arranged on the workbench 3 through a mounting block 15. Specifically, the mounting block 15 is fixedly locked with the workbench 3 through a locking screw 12. The punching device 1 is fixed on the mounting block 15 through four mounting screws 16 for convenient repair use.

[0088] The punching device 1 is installed in the middle of the workbench 3. One set of alignment device 5 is installed on each of the left and right sides of the punching device 1, which is for convenient use and improving the repair efficiency. When installing the alignment device 5, first accurately position the alignment device 5 by using two positioning pins 11, and then fix and lock it with screws.

[0089] The alignment device 5 includes a positioning seat 14, a flipping plate 9, and a positioning member 6. The flipping plate 9 is rotatably connected to the positioning seat 14 through a hinge shaft 8, and one end of the hinge shaft 8 is clamped into a snap spring 10 to prevent the hinge shaft 8 from falling out. A handle 7 is fixedly installed on the flipping plate 9 through screws, facilitating the flipping operation. A chute 91 is provided at the front end of the flipping plate 9, and the positioning member 6 is slidably installed in the chute 91 to cooperate to achieve the positioning function. Two limit screws are installed on the positioning member 6 at intervals, capable of accurately controlling the up and down movement distance of the positioning member 6.

[0090] The punching repair tooling for the photovoltaic water tank of the present invention solves the problem of uneven positions of the rework holes through the alignment device 5, and improves the repair efficiency. In addition, by arranging two groups of alignment devices 5 at the same time, the operations of aligning the two sides respectively can be realized, reducing the processing cost and improving the processing efficiency at the same time.

[0091] Although the 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.
