Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a welding fixture for a photovoltaic frame base. Background Technology

[0002] As the main supporting component of a photovoltaic (PV) frame, the base of the PV frame primarily serves to install columns, inclined beams, and other parts. To facilitate processing, the base is typically divided into two parts: a base plate and a support frame. After bending and punching, these two parts are manufactured and then vertically welded together to form the base. In actual welding, the base plate is usually placed directly in a fixture, and the support frame is aligned with it. Spot welding is then used to fix them in place before welding at the joint. However, to facilitate removal of the base from the fixture after welding, only the two vertical sides of the support frame are typically provided with restraints, while the other two sides are manually restrained. This can cause the support frame to shift under external forces, reducing welding precision and potentially even rendering the product unusable. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a photovoltaic frame base welding fixture, which can apply limiting to both the base plate and the periphery of the support to ensure welding accuracy. In addition, it is easy to remove while adapting to different sizes, and has strong practicality.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A photovoltaic frame base welding fixture includes: a workbench, a load-bearing component, and a positioning component.

[0006] The top of the workbench has a rectangular hole that runs vertically through it. The support assembly includes four support plates located on the inner sides of the rectangular hole. The support plates are movable along the length or width of the rectangular hole to support the base plate. A detachable locking block is located above the support plate to limit the periphery of the base plate. The positioning assembly is located above the workbench and includes a U-shaped frame that moves along its length. Two symmetrically arranged and opposing clamping blocks are located inside the U-shaped frame to limit the sides of the support. A limiting block is located above the U-shaped frame, between the clamping blocks, and moves along the length of the workbench to limit the inner side of the support.

[0007] Furthermore, the support plate is in the shape of an inverted L, and a support rod is provided on the outside. The support rod passes through the workbench, and the outside of the support plate is connected to the moving end of the telescopic rod. The telescopic rod is installed at the bottom of the workbench.

[0008] Furthermore, a T-shaped block is provided on the outer side of the card block, and four protrusions are provided on the top surface of the worktable, which are located around the rectangular hole respectively. The top of the protrusions is provided with a T-shaped groove, and the T-shaped block fits into the T-shaped groove.

[0009] Furthermore, a sliding rod is provided on the outside of the clamping block. The sliding rod passes through the end of the U-shaped frame. A connecting block is provided at the end of the sliding rod. A connecting rod is rotatably connected to the connecting block. One end of the connecting rod is rotatably connected to the moving block. The moving block is sleeved on the first screw and locked with a nut. The first screw is installed on the U-shaped frame.

[0010] Furthermore, the top surface of the U-shaped frame is provided with a vertical rod, and a top plate is fitted on the vertical rod. The top plate is provided with a sliding groove along its length. The upper end of the limiting block is slidably fitted in the sliding groove and fitted on the second screw, and locked with a nut. The second screw is installed on the top plate and arranged along its length.

[0011] Furthermore, two mounting plates are provided on the outer side of the U-shaped frame. The top surface of the mounting plate has a long through hole running vertically along its length. A limit rod slides in the long through hole. The limit rod is installed on the side plate. The side plate is installed on the workbench, and its top surface contacts the bottom surface of the mounting plate. A third screw is provided at the end of the mounting plate. The third screw passes through the side plate and is locked with a nut.

[0012] The advantages of this utility model are as follows: the clamping block limits the periphery of the base plate, while the U-shaped frame, clamping plate, and limiting block limit the periphery of the support, thereby ensuring that the support and base plate will not shake during the welding process, thus ensuring welding accuracy and adapting to different size requirements; the support plate can move, so that the base can automatically fall under the action of gravity after welding, realizing rapid transfer of the base and improving welding efficiency.

[0018] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1-4 As shown, this example provides a photovoltaic frame base welding fixture, including: a workbench 100, a load-bearing component 200, and a positioning component 300.

[0020] The top of the workbench 100 has a rectangular hole 101 that runs vertically through it. The support assembly 200 includes four support plates 201 respectively located on the inner sides of the rectangular hole 101. The support plates 201 located on both sides of the length direction of the rectangular hole 101 are movable along the width direction of the rectangular hole 101, while the support plates 201 located on both sides of the width direction of the rectangular hole 101 are movable along the length direction of the rectangular hole 101, for supporting the bottom plate. The support plates 201 are provided with detachably connected locking blocks 202 for limiting the periphery of the bottom plate. The positioning assembly 300 is located above the workbench 100 and includes a U-shaped frame 301 that moves along its length direction. One side of the frame abuts against the bottom of the inner side of the U-shaped frame 301. The inner side of the U-shaped frame 301 is provided with two symmetrically arranged and opposing clamping blocks 302 for limiting the sides of the frame. The U-shaped frame 301 is provided with a limiting block 303 located between the clamping blocks 302 and moving along the length direction of the workbench 100, for limiting the inner side of the frame.

[0021] Specifically, the support plate 201 is inverted L-shaped and has a support rod 203 on its outer side. The support rod 203 passes through the workbench 100 to provide support for the support plate 201. The outer side of the support plate 201 is connected to the moving end of the telescopic rod 204. The telescopic rod 204 is installed at the bottom of the workbench 100. After welding is completed, the support plate 201 is driven to move away from the center of the rectangular hole 101 by the telescopic rod 204. The support plate 201 no longer provides support for the base plate, and the welded base can fall automatically under the action of gravity.

[0022] Specifically, a T-shaped block 205 is provided on the outer side of the card block 202, and four protrusions 102 are respectively located around the rectangular hole 101 on the top surface of the workbench 100. A T-shaped groove 103 is provided on the top of the protrusion 102, and the T-shaped block 205 is fitted into the T-shaped groove 103, which facilitates the disassembly of the card block 202. When it is necessary to weld base plates of different sizes, different card blocks 202 can be replaced.

[0023] Specifically, a sliding rod 304 is provided on the outer side of the clamping block 302. The sliding rod 304 passes through the end of the U-shaped frame 301. A connecting block 305 is provided at the end of the sliding rod 304. A connecting rod 306 is rotatably connected to the connecting block 305. One end of the connecting rod 306 is rotatably connected to the moving block 307. The moving block 307 is sleeved on the first screw 308 and locked with a nut. The first screw 308 is installed on the U-shaped frame 301. By moving the moving block 307 along the axial direction of the first screw 308, the two clamping blocks 302 can be moved towards each other or in opposite directions, thereby adjusting the distance between the two clamping blocks 302 to accommodate brackets of different widths.

[0024] Specifically, the top surface of the U-shaped frame 301 is provided with a vertical rod 309, and a top plate 310 is sleeved on the vertical rod 309. The top plate 310 is provided with a sliding groove 311 along its length direction. The upper end of the limiting block 303 is slidably fitted in the sliding groove 311 and sleeved on the second screw 312 and locked with a nut. The second screw 312 is installed on the top plate 310 and arranged along its length direction. When the bracket is limited, the upper end of the bracket is located between the limiting block 303 and the bottom of the inner side of the U-shaped frame 301. At this time, the bottom surface of the top plate 310 abuts against the top of the bracket under its own weight, while the side of the limiting block 303 contacts the inner side of the bracket, and the outer side of the bracket contacts the bottom of the inner side of the U-shaped frame 301, thereby realizing the all-round limitation of the bracket, preventing it from shaking and ensuring welding accuracy.

[0025] Specifically, the U-shaped frame 301 has two mounting plates 313 on its outer side. The top surface of the mounting plate 313 has a through-hole 314 along its length. A limit rod 104 slides in the through-hole 314. The limit rod 104 can guide the movement of the mounting plate 313. The limit rod 104 is mounted on the side plate 105, which is mounted on the workbench 100. The top surface of the side plate 105 is in contact with the bottom surface of the mounting plate 313, which can provide a certain support for the mounting plate 313. The end of the mounting plate 313 is provided with a third screw 315, which passes through the side plate 105 and is locked with a nut. This allows the U-shaped frame 301 to move to adapt to different connection positions between the base plate and the support.

[0026] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
