Description

Technical Field

[0001] This invention relates to a positioning device for a swing bracket, a double-ear seat, and a positioning method for the swing bracket, belonging to the technical field of heliostat swing bracket processing tooling. Background Technology

[0002] As human society continues to develop, the demand for energy is constantly increasing. New energy technologies are emerging and making significant contributions to optimizing the social energy structure, with solar photovoltaic power generation being one of the key technologies. Compared to traditional energy sources, solar energy has advantages such as being renewable, green, safe, and environmentally friendly, playing a crucial role in the healthy development of my country's energy and power industries. A large number of photovoltaic power generation projects have emerged, and heliostats, as key equipment, significantly impact the operation of these projects due to their product quality.

[0003] The oscillating support is one of the most critical structural components of a heliostat. Due to its poor structural rigidity, large amount of welding, high precision, and interchangeability, the manufacturing technology of the oscillating support is a key aspect of heliostat structural components. If the oscillating support is manufactured using conventional methods, relying on manual marking, assembly, and welding, its poor rigidity and large amount of welding will lead to uncontrollable deformation, making it impossible to guarantee the dimensional accuracy of the shafts. Simultaneously, the end faces of each shaft require galvanizing, symmetry, parallelism, and perpendicularity to the centerline. This necessitates machining the end faces as a whole after the structural component is manufactured, resulting in low efficiency, dimensional inconsistencies, and failure to meet interchangeability requirements. Therefore, it cannot meet the industry characteristics of "low cost, high quality, interchangeability, and short delivery time" for mass production of heliostat structural components. Therefore, to address the above issues, the oscillating support is manufactured in two stages, with specialized tooling designed to reduce manufacturing processes, meet product precision requirements, and achieve interchangeability.

[0004] Traditional manufacturing process: material preparation - marking - assembly - manual welding - straightening - grinding - end face machining - hot-dip galvanizing - hole machining - repair.

[0005] Analysis revealed that the manual manufacturing process for the swing bracket is lengthy, inefficient, and requires highly skilled personnel, resulting in a lack of interchangeability. Furthermore, the swing bracket requires two complete machining processes, increasing the number of steps and machine tool usage, further hindering efficiency and impacting the overall product delivery cycle.

Detailed Implementation

[0049] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0050] Any feature disclosed in this specification, unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.

[0051] Example 1

[0052] A positioning device for a heliostat swing bracket, such as Figures 1-8 As shown, it includes a double-ear seat fixture for positioning the double-ear seat and a swing bracket fixture for positioning the swing bracket.

[0053] The double-ear seat tooling includes a tooling base 101, on which a first positioning plate 102 and a second positioning plate 103 for assembling the double-ear seat ear plate 301 are provided, as well as a third positioning plate 104 for positioning the end of the double-ear seat. The first positioning plate 102 and the second positioning plate 103 are arranged opposite to each other, and the third positioning plate 104 matches the end face of the double-ear seat.

[0054] The swing bracket fixture includes a fixture base plate 201. One end of the fixture base plate 201 is provided with a fourth positioning plate 202 and a fifth positioning plate 203 for assembling the end of the double ear plate 301, and a ninth positioning plate 207 for matching the end face of the double ear plate. The fourth positioning plate 202 and the fifth positioning plate 203 are assembled opposite to each other. The other end of the fixture base plate 201 is provided with a sixth positioning plate 204, a seventh positioning plate 205, and an eighth positioning plate 206 for assembling the end of the swing arm. The sixth positioning plate 204 and the seventh positioning plate 205 are assembled opposite to each other and are used to assemble the middle part of the swing arm. The eighth positioning plate 206 matches the end face of the swing arm. The base plate is also provided with a support assembly for support.

[0055] In this embodiment, the specific structural design primarily considers the formation of the swing bracket. To better achieve positioning during the processing of the entire swing bracket, a double-ear fixture structure is used to assemble and position the double ear seats. This is also the first and fundamental step in the entire swing bracket processing. Furthermore, based on the assembly method of the entire swing bracket fixture, the remaining swing arms are further positioned and processed. In this design, axial positioning is achieved using multiple positioning plates, radial positioning is achieved using paired positioning plates similar to ear plates, and vertical positioning is achieved using support components. This effectively achieves three-dimensional positioning, further ensuring positioning accuracy while simultaneously guaranteeing clamping efficiency, thus effectively improving the production efficiency of the swing bracket for mass production.

[0056] Based on the aforementioned structural design, the double-ear seat fixture further includes a first positioning block 105 disposed on the fixture base 101 and located below the third positioning plate 104. The first positioning block 105 can match the bottom of the double-ear seat base plate 302 to achieve positioning. As a specific structural design, this design can effectively position the bottom of the double-ear seat base plate 302, achieving higher precision positioning.

[0057] In conjunction with the above specific structural design, more specifically, the end face of the third positioning plate 104 that matches the end face of the double ear seat is also provided with a first groove 106.

[0058] Based on the above specific structural design, as a further design, the first positioning plate 102 and the second positioning plate 103 are provided with through holes that match the double ear seat, and are assembled and fastened one by one by bolts.

[0059] The third positioning plate 104 has a through hole in the middle that matches the end face of the double ear seat, and the end face of the double ear seat can be fitted and fastened to the positioning surface of the third positioning plate 104 by means of the pin bolt assembly 4.

[0060] In the above-mentioned specific structural design, the design of two positioning plates can effectively position the double ear plate 301.

[0061] As a more specific design, the overall clamping and positioning of the swing bracket is also carried out in three directions to achieve a better positioning effect. Therefore, a second positioning block 208 matching the single ear plate 307 at the end of the swing arm is also provided on the working base plate. The second positioning block 208 is located at the lower part of the seventh positioning plate 205.

[0062] Based on the above specific structural design, and more specifically, the fourth positioning plate 202 and the fifth positioning plate 203 are provided with through holes that match the double ear plate 301, and the double ear plate 301 can be fixedly assembled by the pin bolt assembly 4.

[0063] The sixth positioning plate 204 and the seventh positioning plate 205 are provided with through holes that cooperate with the middle part of the rocker arm, and the middle part of the rocker arm can be fixedly assembled by the pin bolt assembly 4, and is located on the outside of the rocker wall.

[0064] The eighth positioning plate 206 is provided with a through hole that matches the single ear plate 307 at the end of the swing wall, and the end of the swing arm can be fixedly assembled by the pin bolt assembly 4.

[0065] In the design of this structure, the main consideration is the stress points of the entire swing bracket. After determining the relevant stress points through the structure, the structural design of the tooling is further optimized. The design of this structure enables the precise positioning of the swing bracket. At the same time, the assembly effect during the entire swing bracket processing is also taken into account. The design of the relevant structure effectively realizes the precise positioning of the entire tooling during the processing.

[0066] Based on the above-mentioned specific structural design, the design is further optimized. The support components include a first support component and a second support component. The tops of the first and second support components support the partition 304 at the bottom of the swing bracket. The second support component includes a second support plate 210, which matches the end face of the double-ear seat. In this structural design, the bottom of the swing arm of the swing bracket is mainly considered to be the partition 304. To better support the partition 304 and the side plate 305, two sets of support components are used as the bottom support in this design. By accurately locating the bottom fulcrum of the swing arm, the height positioning is effectively achieved, ensuring the positioning accuracy of the entire swing bracket when welded together.

[0067] Based on the specific structural design described above, the first support assembly further includes a first support plate 209. A protrusion 214 is provided in the middle of the first support plate 209. The height of the protrusion 214 is the same as the top height of the second support plate 210. The top of the first support plate 209, located on both sides of the protrusion 214, supports the bottom of the swing arm side plate 305. To further optimize the structure, in this embodiment, the second support plate 210 and the ninth positioning plate 207 are the same plate.

[0068] As a more specific design, the support assembly also includes a third support assembly for supporting the bottom of the rocker arm. This third support assembly has at least two sets of third support plates 211 that match the height of the bottom of the assembled rocker arm. This structural design allows for separate support of the side plate 305, primarily considering that the heights of the side plate 305 and the partition plate 304 are not identical, thus effectively ensuring the positioning of each component.

[0069] Based on the aforementioned structural design, more specifically, the second support plate 210 is provided with a through hole matching the end face of the double-ear seat. A connecting block 213 is fixedly provided on the outer side of the fourth positioning plate 202 and the fifth positioning plate 203. A threaded hole corresponding to the through hole on the second support plate 210 is provided in the middle of the connecting block 213. The double-ear seat can be assembled and positioned by matching the threaded hole on the connecting block 213, the through hole on the support plate, and the through hole on the end face of the double-ear seat with the pin bolt assembly 4. The three holes maintain axial alignment. This structural design effectively ensures the stability of the entire double-ear seat and provides better positioning performance.

[0070] In a more specific design, the eighth positioning plate 206 is also equipped with a U-shaped clamp assembly for assembling the single ear plate 307 of the swing bracket. The U-shaped clamp assembly includes two U-shaped clamps 212, which are respectively disposed on both sides of the eighth positioning plate 206. The grooves of the U-shaped clamps 212 can hold the eighth positioning plate 206 and the single ear plate 307. During the assembly of the positioning plate, the fit of the single ear plate 307 can be effectively guaranteed, further ensuring the axial positioning effect of the entire structure and achieving a higher precision positioning effect.

[0071] Based on the above, in the overall structural design, every surface of the tooling (including the double-ear tooling and the swing bracket tooling) that matches the swing bracket is machined with a smooth surface, mainly to ensure the accuracy of the entire structure.

[0072] Example 2

[0073] Regarding the positioning fixture of Embodiment 1, the structure of the swing bracket is further specified in conjunction with the fixture. Specifically, the swing bracket includes a double ear seat and a swing arm. The double ear seat includes a pair of parallel double ear seat ear plates 301 with through holes. A double ear seat base plate 302 with through holes is fixedly provided at one end of the ear plate without through holes. A cover plate 303 is also provided on the upper side of the ear plate.

[0074] The rocker arm includes a partition 304, and side plates 305 are fixedly mounted on both sides of the partition 304. One end of the side plate 305 is matched and fixedly connected to the double-ear base plate 302, and a single-ear plate 307 is fixedly provided at the other end. A bushing 306 is also provided between the side plates 305, and its two ends are fixedly mounted to the side plates 305 respectively and matched with the through holes on the side plates 305.
