Description
Technical Field

Solar thermal power generation with energy storage function is a grid-friendly power generation method and can be used as a basic load power source like nuclear power and thermal power. As a key equipment in the solar thermal power generation concentrating and collecting system, the manufacturing quality of heliostats is directly related to whether the concentrating and collecting system can operate safely and reliably, and whether various assessment indicators can meet the design requirements. The high-precision operation of heliostats is guaranteed by high-precision bracket components. The special-shaped structural components in the special design of heliostats have high precision requirements and are very difficult to manufacture.

[0027] Example
[0028] Please refer to Figure 1-5 This embodiment provides a heliostat center disk positioner welding tool, which is used to clamp the center disk 1 to facilitate the welding of the center disk 1. Figure 1 As shown, the small flange on the top is the second flange 12 , and the large flange on the bottom is the first flange 11 . The welding fixture of this embodiment is connected with the first flange 11 and the second flange 12 to achieve the clamping of the center disk 1 .
[0029] Specifically, the heliostat center disk positioner welding tooling of this embodiment includes a positioner mechanism having an active rotating part and a driven rotating part, an active terminal tooling 31 and a driven terminal tooling 32. The positioner mechanism adopts an existing commercially available positioner, or adopts a structure with the same function as the commercially available positioner 2. This embodiment adopts a commercially available H-type positioner 2, which has an active end connection disk and a driven end connection disk, that is, the active rotating part and the driven rotating part.
[0030] The active terminal tooling 31 includes a workpiece support 311 with an active connecting plate 316. The workpiece support 311 is connected to the active end connecting plate and rotates synchronously. The active connecting plate 316 is close to the first flange 11. The active connecting plate 316 is provided with a pair of first positioning blocks 312. The first positioning block 312 has a positioning inclined surface. The two first positioning blocks 312 are symmetrically distributed on both sides of the first flange 11. The first flange 11 is supported by the positioning inclined surfaces of the first positioning blocks 312 to achieve support and positioning of the first flange 11. It should be noted that the first positioning block 312 can be circular, triangular, quadrilateral, etc., as long as it has a positioning inclined surface supporting the first flange 11. The first positioning block 312 in this embodiment adopts a triangular triangular block. In order to install the first positioning block 312, the active connecting plate 316 is also provided with a first pad 313 and a first bottom plate 314. One first positioning block 312 corresponds to one first pad 313 and one first floor. The first pad 313 is installed on the left vertical side / right vertical side of the active connecting plate 316. At the same time, the first pad 313 is connected to the first positioning block 312. The first bottom plate 314 is installed on the lower bottom edge of the active connecting plate 316 and connected to the first positioning block 312.
[0031] In order to fix the first flange 11 after the first flange 11 of the center disk 1 is close to the active connecting plate 316, this embodiment sets a connecting key bar 315 on the workpiece support 311, and the connecting key bar 315 and the first flange 11 are respectively located on both sides of the active connecting plate 316, and then a number of tensioning threaded rods are used to penetrate the connecting key bar 315, the first flange 11 and the active connecting plate 316 and lock the three to achieve the fixation of the first flange 11.
[0032] The driven terminal fixture 32 includes a driven connecting plate 321 connected to the second flange 12, a slider fixing member 322, and a slider connecting member 323 connected to the driven connecting plate 321. The slider fixing member 322 is connected to the driven connecting plate, and the slider connecting member 323 is slidably connected to the slider fixing member 322, for example, by a linear guide rail, and a stop plate 327 is also provided on the slider fixing member 322 to prevent the slider connecting member 323 from being separated from the slider fixing member 322.
[0033] The driven connecting plate 321 is provided with a pair of second positioning blocks 324, which have a positioning inclined surface. The two second positioning blocks 324 are symmetrically distributed on both sides of the second flange 12. The second flange 12 is supported by the positioning inclined surfaces of the second positioning blocks 324 to achieve support and positioning of the second flange 12. It should be noted that the second positioning block 324 can be circular, triangular, quadrilateral, etc., as long as it has a positioning inclined surface supporting the second flange 12. The second positioning block 324 in this embodiment adopts a triangular triangular block. In order to install the second positioning block 324, the active connecting plate 316 is also provided with a second pad 325 and a second bottom plate 326. One second positioning block 324 corresponds to one second pad 325 and a second floor. The second pad 325 is installed on the left vertical side / right vertical side of the driven connecting plate 321. At the same time, the second pad 325 is connected to the second positioning block 324. The second bottom plate 326 is installed on the lower bottom side of the driven connecting plate 321 and is connected to the second positioning block 324. After the second flange 12 of the center plate 1 is placed on the second positioning block 324 , the second flange 12 and the driven connecting plate 321 can be fixed by bolts.
[0034] When this embodiment is in use, the center disk 1 is placed between the active terminal tooling 31 and the driven terminal tooling 32, and the first flange 11 is fixed to the active terminal tooling 31, and the second flange 12 is fixed to the driven terminal tooling 32, and then the positioner 2 is started, and the center disk 1 can be rotated as needed to facilitate the welding operation. If this embodiment is combined with an automatic welding robot, automatic welding of the center disk 1 can be achieved. When clamping the center disk 1 before welding, due to different center disks 1, the size may be slightly different. Therefore, a structure in which a slider connector 323 and a slider fixing member 322 are slidably connected in the driven terminal tooling 32 is adopted to achieve an adjustable overall length of the driven terminal tooling 32, so as to facilitate the clamping of the center disk 1 with a size deviation. It should be noted that the aforementioned "different center disks 1 may have some differences in size", and the overall length adjustment range of the driven terminal tooling 32 can cover the size deviation. When the center disk 1 is cooling after welding, the center disk 1 continues to remain in the clamping state until the cooling is completed. During the cooling of the center disk 1, since the active terminal tooling 31 and the driven terminal tooling 32 simultaneously constrain the center disk 1, the deformation degree of the center disk 1 will be reduced. In the prior art, when the center disk 1 is cooled after welding, there is no external constraint, and the center disk 1 can deform freely. In addition, due to the characteristics of small steel plate thickness, poor rigidity, large welding volume, easy deformation during welding, and high precision requirements, the center disk 1 will produce uncontrollable welding deformation, unable to ensure dimensional accuracy requirements, affecting the product qualification rate, and low efficiency, unable to meet the requirements of short delivery time. Compared with the prior art, when the center disk 1 is cooling after welding, the tooling of this embodiment is used to constrain it, which can effectively control the welding deformation of the center disk 1 and improve the welding quality and quality stability.

For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
