Description

Technical Field

[0001] This invention relates to the technical field of heliostat main beam processing equipment, and more specifically, to a heliostat main beam positioning and vibration damping component and a heliostat main beam drilling device. Background Technology

[0002] In solar thermal power generation technology, the heliostat is one of the core components, and the machining accuracy of its main beam directly affects the efficiency and stability of the entire system. Existing drilling equipment for heliostat main beams typically uses a single clamping point or a rigid fixing method for the main beam positioning and clamping mechanism. However, this design cannot effectively cope with positioning deviations caused by deformation and vibration during drilling of the long axially elongated main beam, especially in double-layer drilling operations where vibration is more significant, thus posing a severe challenge to the stability and machining accuracy of the main beam during drilling.

[0003] Currently, existing devices for positioning the main beam typically use three-jaw calipers to radially clamp and fix the heliostat main beam, or use a method of squeezing the main beam on both radial sides to fix it. Both of these fixing methods not only squeeze the main beam, causing it to deform significantly, but also fail to buffer the minor vibrations during the main beam's processing, leading to reduced drilling accuracy.

[0004] Therefore, the existing heliostat main beam positioning device has the problem that it cannot effectively control the vibration during the processing and causes the main beam to undergo large radial deformation, resulting in poor processing accuracy. This problem urgently needs to be solved. Summary of the Invention

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figures 1 to 4 As shown, an embodiment of the present invention provides a heliostat main beam positioning and vibration damping assembly for fixing a heliostat main beam 30. At least one main beam mounting member is spaced along the axis of the heliostat main beam 30. The heliostat main beam positioning and vibration damping assembly includes at least one positioning clamping structure 10 and at least one vibration damping structure 20. The positioning clamping structure 10 includes an axial limiting part 11 and a radial fixing part 12. The axial limiting part 11 is configured to cooperate with the main beam mounting member to axially limit the heliostat main beam 30; the radial fixing part 12 is configured to... The structure is capable of supporting the heliostat main beam 30 and radially limiting the heliostat main beam 30; the vibration damping structure 20 includes a mating part 21, an elastic component 22 and a fixed base 23. The mating part 21 is directly or indirectly slidably disposed on the fixed base 23. The mating part 21 is configured to clamp or connect to the main beam mounting component; the elastic component 22 is disposed on the fixed base 23. The elastic component 22 is configured to act directly or indirectly on the mating part 21 to buffer the vibration generated during the processing of the heliostat main beam 30 through the elastic force of the elastic component 22.

[0031] This invention, through the coordinated operation of a positioning clamping structure 10 and a vibration damping structure 20, not only provides support, axial restraint, and radial restraint for the heliostat main beam 30, but also effectively controls the vibration of the heliostat main beam 30 and / or the main beam mounting components during subsequent processing, thereby ensuring the processing accuracy of subsequent steps. Specifically, the positioning clamping structure 10 includes an axial restraint part 11 and a radial fixing part 12. The axial restraint part 11 is used to axially restrain the heliostat main beam 30, and the radial fixing part 12 is used to support the heliostat main beam 30 and radially restrain it. The vibration damping structure 20 includes a mating part 21, an elastic component 22, and a fixed base 23. One end of the mating part 21 is slidably disposed in the fixed base 23, and the other end engages with the main beam mounting components on the heliostat main beam 30. When processing the heliostat main beam 30 or the main beam mounting components, the vibration generated during processing is transmitted to the mating part 21 via the main beam mounting components. Since the axial limiting part 11 and the radial fixing part 12 respectively form axial and radial constraints on the heliostat main beam 30, the vibration energy will eventually be transmitted to the main beam mounting component, thereby driving the mating part 21 to slide relative to the fixed base 23, causing the mating part 21 to compress or stretch the elastic component 22. The elastic component 22 absorbs the vibration energy through its own elastic deformation, thereby effectively buffering the vibration generated during the processing and reducing the impact of vibration on the processing accuracy. By setting the anti-vibration structure 20, the vibration generated by the heliostat main beam 30 and / or the main beam mounting component during the drilling process can be effectively absorbed, ensuring the stability of the heliostat main beam 30 and the main beam mounting component on it in the processing state. In practical applications, this heliostat main beam positioning anti-vibration component can significantly improve the stability of the heliostat main beam 30 during the processing, especially in drilling operations, effectively reducing processing errors caused by vibration and improving the processing quality of the product. Furthermore, the precise fit between the positioning and clamping structure 10 and the vibration damping structure 20 not only ensures the machining accuracy of the heliostat main beam 30 and / or the main beam mounting components, but also reduces abnormal stress on the axial limiting part 11 and the radial fixing part 12 during machining, helping to extend the service life of the equipment and reduce maintenance costs. The structural design of this component gives it good flexibility and adjustability, enabling it to adapt to different sizes and types of heliostat main beams 30, improving machining diversity and efficiency. This invention has a compact structure, is easy to assemble and maintain, and effectively solves the problems in the prior art where the heliostat main beam positioning device cannot effectively control machining vibration and where the heliostat main beam 30 is prone to radial deformation during machining, showing good prospects for widespread application.

[0032] It should be noted that the axial direction mentioned in this application is with reference to the heliostat main beam 30, and the aforementioned axial direction is the extension direction of the heliostat main beam 30; the radial direction is the direction of extension with reference to the radius of the heliostat main beam 30.

[0033] It should also be noted that the engagement method between the mating part 21 and the main beam mounting component can be selected according to actual needs. In some embodiments, the mating part 21 is fixedly connected to the main beam mounting component by fasteners; in other embodiments, the mating part 21 is engaged with the main beam mounting component by clamping. This application does not limit the engagement method of the mating part 21. Similarly, the specific structure of the fixing base 23 can be designed according to actual installation requirements. In some embodiments, the fixing base 23 is an independent base structure; in other embodiments, the fixing base 23 is configured as a mounting seat suitable for fixed connection with processing equipment. This application also does not limit the specific structure of the fixing base 23. Of course, this application also does not limit the specific structure of the main beam mounting component; it can be specifically designed according to actual conditions.

[0034] In a specific embodiment of the present invention, the mating part 21 in the vibration damping structure 20 includes a bidirectional drive mechanism 211 and two clamping blocks 212. The bidirectional drive mechanism 211 has a body and a first telescopic end and a second telescopic end that can extend and retract in opposite directions. The body is slidably disposed on the fixed base 23. The two clamping blocks 212 are respectively installed on the first telescopic end and the second telescopic end and are used to clamp the main beam mounting component. The elastic component 22 includes at least one elastic member. The at least one elastic member is disposed on at least one side of the bidirectional drive mechanism 211 along the sliding direction of the bidirectional drive mechanism 211. Each elastic member has one end disposed on the bidirectional drive mechanism 211 and the other end disposed on the fixed base 23.

[0035] Specifically, the mating part 21 includes a bidirectional drive mechanism 211 and two clamping blocks 212. The body of the bidirectional drive mechanism 211 is slidably mounted on the fixed base 23. Its first telescopic end and second telescopic end extend and retract synchronously in opposite directions, respectively driving the two clamping blocks 212 to clamp the main beam mounting component, thereby achieving symmetrical bidirectional clamping of the main beam mounting component and reducing the vibration of the main beam mounting component itself caused by processing vibration. Since the axial and radial directions of the heliostat main beam 30 are limited by the positioning and clamping structure 10, during the processing of the heliostat main beam 30 or the main beam mounting component, vibration impact is transmitted through the main beam mounting component to the clamping blocks 212, causing the bidirectional drive mechanism 211 to slide along the fixed base 23. To buffer this vibration, at least one elastic member is provided on at least one side of the sliding direction of the bidirectional drive mechanism 211, and the two ends of the elastic member are respectively connected to the bidirectional drive mechanism 211 and the fixed base 23. When the bidirectional drive mechanism 211 slides on the fixed base 23, the elastic component absorbs vibration energy through elastic deformation, thereby effectively suppressing the displacement of the mating parts caused by vibration and improving the dynamic stability and processing accuracy of the vibration-damping structure 20.

[0036] In another specific embodiment of the present invention, the mating part 21 in the vibration damping structure 20 includes a connecting member, the connecting member having a sliding part and an extension connected to the sliding part, the sliding part being slidably disposed on the fixed base 23, and the extension being used to connect to the main beam mounting member by fasteners; wherein, the elastic component 22 includes at least one elastic member, at least one elastic member being disposed on at least one side of the sliding part of the connecting member along the sliding direction of the connecting member, and one end of each elastic member being disposed on the sliding part, and the other end of each elastic member being disposed on the fixed base 23.

[0037] Specifically, the mating part 21 is a connecting member that reliably connects with the main beam mounting member. This connecting member includes a sliding part and an extension part. The sliding part can slide along the fixed base 23, while the extension part is fixed to the main beam mounting member by fasteners (such as bolts, screws, rivets, or clips, or one or more combinations thereof). The elastic component 22 consists of at least one elastic member. The elastic member is arranged along the sliding direction of the connecting member on at least one side of the sliding part, with one end of each elastic member fixed to the sliding part and the other end fixed to the fixed base 23. When the heliostat main beam 30 and / or the main beam mounting member vibrate during processing, the vibration is transmitted through the main beam mounting member to the extension part, and then absorbed and dissipated by the elastic member through the sliding part in a directional manner via tensile and compressive deformation. This effectively suppresses the offset of the mating part 21 in the non-target direction, improving the stability and accuracy of the buffer, thereby ensuring that the heliostat main beam 30 or the main beam mounting member maintains good axial and radial positioning capabilities during processing, avoiding deformation accumulation and processing errors caused by vibration.

[0038] In another specific embodiment of the present invention, the mating part 21 in the vibration damping structure 20 includes a bidirectional drive mechanism 211, a sliding member, and two clamping blocks 212. The sliding member is slidably disposed on the fixed base 23. The bidirectional drive mechanism 211 has a body and a first telescopic end and a second telescopic end that can extend and retract in opposite directions. The body is disposed on the sliding member. The two clamping blocks 212 are respectively installed on the first telescopic end and the second telescopic end and are used to clamp the main beam mounting member. The elastic component 22 includes at least one elastic member. The at least one elastic member is disposed on at least one side of the sliding member along the sliding direction of the sliding member. Each elastic member has one end disposed on the sliding member and the other end disposed on the fixed base 23.

[0039] Specifically, such as Figure 1 and Figure 2As shown, the mating part 21 includes a sliding member and a bidirectional drive mechanism 211. The sliding member is slidably mounted on the fixed base 23, and the body of the bidirectional drive mechanism 211 is fixed to the sliding member. The first telescopic end and the second telescopic end of the bidirectional drive mechanism 211 extend and retract synchronously in opposite directions, respectively driving two clamping blocks 212 to clamp the main beam mounting component, thereby achieving symmetrical bidirectional clamping of the main beam mounting component. During the processing of the heliostat main beam 30 or the main beam mounting component, when vibration and impact are transmitted to the main beam mounting component, the two clamping blocks 212 clamping the component cause the sliding member to move together. To buffer the vibration, at least one elastic member is provided on at least one side of the sliding direction of the sliding member, and the two ends of the elastic member are respectively connected to the sliding member and the fixed base 23. When the sliding member slides on the fixed base 23, the elastic member absorbs the vibration energy along the sliding direction through elastic deformation, thereby suppressing the displacement of the sliding member caused by vibration. Through the above structure, this embodiment can absorb vibration energy through the elastic deformation of the elastic component and suppress the displacement of the sliding component, thereby improving the dynamic stability and processing accuracy of the vibration-damping structure 20.

[0040] Furthermore, in embodiments of the present invention, the elastic components 22 can be two or more, such as a first spring 221 and a second spring 222. This arrangement provides a more balanced buffering effect, further reducing axial vibration, while ensuring the stability and reliability of the heliostat main beam positioning and vibration damping assembly. By adjusting the number and strength of the elastic components 22, it is possible to adapt to heliostat main beams 30 of different sizes and weights, enhancing the applicability and processing efficiency of the heliostat main beam positioning and vibration damping assembly. Overall, through the structural design of the fixed base 23, slide rail 232, and elastic components 22, the heliostat main beam positioning and vibration damping assembly of the present invention can effectively control vibration during processing and improve processing accuracy.

[0041] In embodiments of the present invention, the mating part 21 can adopt any of the above-described structures. The fixed base 23 has a mating cavity 231 and a slide rail 232 disposed in the mating cavity 231. All elastic members are disposed in the mating cavity 231. The first direction is the extension direction along the slide rail 232. The side of the mating part 21 with the first telescopic end is the first end, and the side of the mating part 21 with the second telescopic end is the second end. The elastic members are springs, and there are at least two elastic members, including a first spring 221 and a second spring 222. One end of the first spring 221 is connected to or abuts against the inner wall of the mating cavity 231 along the first direction, and the other end of the first spring 221 is connected to the first end of the mating part 21. One end of the second spring 222 is connected to or abuts against the inner wall of the mating cavity 231 along the first direction, and the other end of the second spring 222 is connected to the second end of the mating part 21.

[0042] Specifically, such asFigure 1 and Figure 2 As shown, the fixed base 23 has a mating cavity 231 and a slide rail 232 inside. The elastic component 22 uses at least two springs, namely a first spring 221 and a second spring 222. One end of the first spring 221 abuts or connects to the inner wall of the mating cavity 231 along one end in the first direction, and the other end connects to the first end of the mating part 21. One end of the second spring 222 abuts or connects to the inner wall of the mating cavity 231 along the other end in the first direction, and the other end connects to the second end of the mating part 21. This arrangement allows the mating part 21 to slide bidirectionally along the axial direction on the slide rail 232. During the processing, the vibration energy transmitted by the main beam mounting component is absorbed and dispersed synchronously by the first spring 221 and the second spring 222, effectively reducing the vibration amplitude and improving the clamping stability. At the same time, it avoids the misalignment or jamming of the mating part 21 caused by uneven force on one side of the spring, thereby enhancing the buffering capacity of the heliostat main beam 30 for axial vibration during the drilling process and ensuring positioning accuracy. It should be noted that the two ends of the first spring 221 or the second spring 222 refer to the two ends along its axial direction. When the mating part 21 does not apply external force to the first spring 221 or the second spring 222, both the first spring 221 and the second spring 222 are in their natural state.

[0043] Preferably, the fixing base 23 has a U-shaped structure, consisting of a first base plate and two first vertical plates. The two first vertical plates are parallel and opposite to each other, and are respectively disposed at both ends of the first base plate along its length. The slide rail 232 is installed along the length of the first base plate, and its two ends are respectively fixedly connected to the two first vertical plates.

[0044] In an embodiment of the present invention, the radial fixing part 12 includes a first linear drive mechanism and a support base 123; the support base 123 includes an upper support part and a lower support part, and a first receiving groove is provided on the lower support part of the support base 123; the first linear drive mechanism includes a first fixed end 121 and a third telescopic end 122, and the first fixed end 121 is mounted on the upper support part of the support base 123; wherein, the first receiving groove is configured to accommodate at least a portion of the radial cross-section of the heliostat main beam 30 when the heliostat main beam 30 is mounted on the support base 123; the third telescopic end 122 is configured to extend and press the heliostat main beam 30 when the heliostat main beam 30 is mounted on the support base 123, so as to cooperate with the first receiving groove to achieve radial fixing.

[0045] Specifically, such as Figure 3 and Figure 4As shown, the radial fixing part 12 includes a first linear drive mechanism and a support base 123. The support base 123 is divided into an upper support part and a lower support part. A first receiving groove is provided on the lower support part of the support base 123. Normally, the first receiving groove is an arc-shaped groove adapted to the cross-section of the heliostat main beam 30, and the cross-section is C-shaped. The first receiving groove can accommodate at least a part of the radial cross-section of the heliostat main beam 30, forming a stable bearing base surface. However, in other embodiments of the present invention, the first receiving groove can be a V-shaped groove or a U-shaped groove, etc., and the specific design can be made according to the actual situation, as long as the first receiving groove can accommodate at least a part of the radial cross-section of the heliostat main beam 30. The first fixed end 121 of the first linear drive mechanism is disposed on the upper support part of the support base 123. When the heliostat main beam 30 is placed on the support base 123, the third telescopic end 122 can extend toward the heliostat main beam 30 and directly press against the outer surface of the main beam. Together with the first receiving groove, it forms a clamping radial limiting structure. This structure effectively constrains the radial displacement of the main beam under processing vibration through uniform clamping force, avoids local stress concentration or elastic deformation caused by traditional positioning methods, and improves the stability of the main beam during drilling or cutting. The precise control capability of the first linear drive mechanism ensures that the clamping force is adjustable and does not exceed the limit, which not only ensures the reliability of positioning, but also prevents damage to the surface of the main beam caused by overpressure. Thus, under the synergistic action of the axial limiting part 11 and the radial fixing part 12, the precise fixing of the heliostat main beam 30 is achieved.

[0046] It should be noted that this application does not limit the specific structure of the axial limiting part 11, and the specific structure of the axial limiting part 11 can be designed according to actual needs. In some embodiments, the axial limiting part 11 and the radial fixing part 12 are integrated as two functional components of the same mechanism; in other embodiments, the axial limiting part 11 and the radial fixing part 12 are two independent mechanisms that act on the heliostat main beam 30 respectively.

[0047] Furthermore, the axial limiting part 11 also includes two second linear drive mechanisms 112, both of which are mounted on the lower support part of the support base 123. The lower support part of the support base 123 is also provided with a second receiving groove, which is used to accommodate at least a portion of at least one main beam mounting member when the heliostat main beam 30 is mounted on the support base 123. Each second linear drive mechanism 112 includes a second fixed end 113 and a fourth telescopic end 114, both of which can telescopically enter the second receiving groove to clamp the main beam mounting member located in the second receiving groove when the heliostat main beam 30 is mounted on the support base 123.

[0048] Specifically, such as Figure 3 and Figure 4As shown, the axial limiting part 11 and the radial fixing part 12 are two parts of one mechanism. When the heliostat main beam 30 is mounted on the support base 123, the main beam mounting component is accommodated in the second receiving groove of the lower support part. The fourth telescopic ends 114 of the two second linear drive mechanisms 112 synchronously extend and retract into the second receiving groove and directly abut against the main beam mounting component, thereby achieving axial limiting, suppressing the displacement of the main beam mounting component caused by the axial force during processing, and improving positioning stability. At the same time, the first linear drive mechanism mounted on the upper support part of the support base 123 extends out through the third telescopic end 122 and presses against the main beam mounting component. The heliostat main beam 30 works in conjunction with the first receiving groove of the lower support to achieve radial clamping and limiting of the main beam. In addition, the mating part 21 of the vibration damping structure 20 clamps the main beam mounting components, and the elastic component 22 acts on the mating part 21 through its elastic force to buffer the vibration generated during processing and prevent processing deviations caused by resonance or impact. The above-mentioned axial limiting, radial fixing and vibration buffering work together to form multi-directional limiting constraints, which solves the problem of axial positioning loosening caused by traditional devices relying solely on passive receiving structures, and improves the overall stability and deformation control capability of the main beam in high-precision processing.

[0049] Example 2

[0050] In the second embodiment of the present invention, the main beam mounting components are further defined as positioning supports 32 and beam supports 31. All main beam mounting components include at least one positioning support 32 and at least one beam support 31. The positioning support 32 is fixedly mounted on the heliostat main beam 30, or the positioning support 32 is detachably mounted on the heliostat main beam 30. The beam support 31 is fixedly mounted on the heliostat main beam 30, or the beam support 31 is detachably mounted on the heliostat main beam 30. Each beam support 31 is configured to cooperate with a vibration damping structure 20, and each positioning support 32 is configured to cooperate with an axial limiting part 11.

[0051] Specifically, such as Figures 1 to 4As shown, the heliostat main beam 30 is equipped with a positioning support 32 and a beam support 31. The positioning support 32 is specifically designed to cooperate with the axial limiting part 11 to achieve precise axial positioning of the heliostat main beam 30, avoiding processing deviations caused by axial displacement. The beam support 31 is specifically designed to connect with the mating part 21 of the vibration damping structure 20, allowing the vibration damping structure 20 to apply a buffering force to the beam support 31 through the elastic component 22, effectively absorbing the vibration energy generated during processing. By having the axial limiting function and the vibration damping function independently supported by the positioning support 32 and the beam support 31, respectively, their functions do not interfere with each other, significantly improving assembly consistency and optimizing vibration buffering efficiency. Both the positioning support 32 and the beam support 31 can be fixedly or detachably installed on the heliostat main beam 30, facilitating flexible adjustment of the installation position according to the main beam structure, adapting to the processing requirements of main beams of different specifications, while ensuring stable positioning accuracy and vibration damping performance.

[0052] Furthermore, the radial fixing part 12 includes a first linear drive mechanism and a support base 123. The support base 123 includes an upper support part and a lower support part. The lower support part includes a base and two first support plates. The first end of each first support plate is respectively disposed on the base. The two first support plates are parallel to each other and opposite each other along the thickness direction. The second end of each first support plate is respectively provided with a first receiving groove. The upper support part includes a first linear drive mechanism and a drive structure support base. The drive structure support base is disposed on the base and located on one side of the first support plate along the width direction. The first linear drive mechanism is disposed on the side of the drive structure support base away from the base. The first linear drive mechanism includes a first fixed end 121 and a third telescopic end 122. The first receiving groove is configured to accommodate at least a portion of the radial cross-section of the heliostat main beam 30 when the heliostat main beam 30 is disposed on the support base 123. The third telescopic end 122 is configured to extend and press the heliostat main beam 30 when the heliostat main beam 30 is disposed on the support base 123, so as to cooperate with the first receiving groove to achieve radial fixing.

[0053] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, when the heliostat main beam 30 is mounted on the support base 123, at least a portion of its radial cross-section is accommodated in the first receiving grooves provided at the second ends of the two first support plates. At the same time, the third telescopic end 122 of the first linear drive mechanism extends from the first fixed end 121 and presses against the outer wall of the heliostat main beam 30, so that the first receiving grooves and the third telescopic end 122 jointly clamp the radial cross-section of the main beam from both sides, forming a two-point constrained radial limiting structure. This structure can suppress the local elastic deformation and radial displacement of the main beam caused by cutting force or external disturbance during the processing, thereby improving the positioning stability and processing accuracy. Since the first support plates are parallel to each other and arranged relative to each other along the thickness direction, their support surface for the main beam is uniform and symmetrical, avoiding eccentric deformation caused by unilateral force. As an integral load-bearing structure, the base ensures the consistency of the installation reference of the first receiving groove and the first fixed end 121, so that the clamping force of the third telescopic end 122 can be accurately transmitted to the radially controlled area of ​​the main beam, further enhancing the system's vibration resistance and positioning repeatability.

[0054] Furthermore, the axial limiting part 11 includes a second support plate 111 and two second linear drive mechanisms 112. The two second linear drive mechanisms 112 are respectively mounted on the two first support plates. Each second linear drive mechanism 112 includes a second fixed end 113 and a fourth telescopic end 114. A second receiving groove is provided between the two first support plates. The second receiving groove is used to accommodate a positioning support 32 when the heliostat main beam 30 is set on the support base 123. The second support plate 111 is set on the base and located between the two first support plates. The second support plate 111 is configured to support the positioning support 32 when the heliostat main beam 30 is set on the support base 123. When the heliostat main beam 30 is set on the support base 123, the fourth telescopic ends 114 of the two second linear drive mechanisms 112 can extend and retract along the axial direction of the heliostat main beam 30 to abut against both ends of the positioning support 32 along the axial direction of the heliostat main beam 30.

[0055] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, when the heliostat main beam 30 is placed on the support base 123, the positioning support 32 is accommodated in the second receiving groove formed between the two first support plates, and is stably supported by the second support plate 111 set on the base and located between the two first support plates, ensuring the accurate position of the positioning support 32 in the radial and vertical directions. At the same time, two second linear drive mechanisms 112 are respectively installed on the two first support plates, with their second fixed ends 113 fixed to the first support plates and their fourth telescopic ends 114 extending toward the positioning support 32. When the drive mechanism is started, the fourth telescopic ends 114 on both sides extend synchronously along the axial direction of the heliostat main beam 30, respectively abutting against the two ends of the positioning support 32, forming a bidirectional axial clamping and limiting of the positioning support 32, suppressing the axial displacement caused by cutting force or external disturbance during the processing, thereby improving the positioning accuracy of the heliostat main beam 30. This structure, together with the radial constraint of the radial fixing part 12 and the vibration buffering function of the vibration damping structure 20, achieves a stable processing environment with high precision and low vibration.

[0056] In a specific embodiment of the present invention, the second support plate 111 adopts a support block structure, the second fixed end 113 is one end of the first cylinder structure, the fourth telescopic end 114 is a clamping plate structure and is connected to the first cylinder structure; the first fixed end 121 is one end of the third cylinder structure, the third telescopic end 122 is an arc-shaped plate structure (i.e. an arc-shaped plate structure adapted to the heliostat main beam 30) and is connected to the third cylinder structure; the bidirectional drive mechanism 211 adopts a bidirectional cylinder structure to drive the clamping block 212 to move towards or away from each other.

[0057] The present invention also provides a drilling device for the main beam of a heliostat, which includes the above-mentioned positioning and vibration damping components for the main beam of the heliostat and a drilling assembly for drilling holes in the main beam 30 of the heliostat to be processed.

[0058] Through the effective support and vibration buffering performance of the positioning clamping structure 10 and the vibration damping structure 20, the drilling device for the heliostat main beam to be processed can significantly reduce processing errors caused by vibration of the heliostat main beam 30 and / or main beam mounting components during operation, ensuring the accuracy and quality of drilling operations. Furthermore, the integrated design of the drilling device for the heliostat main beam to be processed helps to shorten the processing flow, improve production efficiency, and also reduces the risk of damage to the heliostat main beam 30, thus helping to extend the service life of the heliostat main beam 30 and reduce maintenance costs.

[0059] The working process and principle of a specific embodiment of the present invention will now be described in detail as follows:

[0060] When drilling the heliostat main beam 30 using the heliostat main beam positioning and vibration damping assembly, the heliostat main beam 30 is first placed on the support seat 123 of the positioning and clamping structure 10, so that the support seat 123 contacts the lower part of the main beam. The second support plate 111 cooperates with the positioning support 32 on the main beam to achieve the initial positioning of the main beam. Subsequently, the axial limiting part 11 abuts against both ends of the positioning support 32 to limit the axial movement of the main beam; the first fixing end 121 of the radial fixing part 12 drives the third telescopic end 122 to abut against the upper part of the main beam to limit the radial movement of the main beam. Afterwards, the bidirectional drive mechanism 211 in the mating part 21 of the vibration damping structure 20 drives the clamping block 212 to clamp the support beam support 31. The first spring 221 and the second spring 222 of the elastic component 22 can be set to a pre-compressed state or a natural state as needed to buffer the axial vibration of the main beam.

[0061] When the drilling assembly begins operation, the elastic component 22 absorbs the axial vibration of the heliostat main beam 30 and its mounting components caused by drilling impact. Guided by the slide rail 232 within the fixed base 23, the mating part 21 can slide slightly along the main beam's axial direction, further mitigating vibration and helping to ensure the accuracy and stability of the drilling operation. Throughout the machining process, the positioning and clamping structure 10 and the vibration damping structure 20 work in coordination to effectively control the vibration of the main beam, reduce machining errors and the risk of component damage, and improve the machining efficiency of the drilling device and the product quality of the main beam. The number and location of the vibration damping structures 20 can be determined according to the number and distribution of the main beam mounting components on the heliostat main beam 30. The adaptable design of the positioning and clamping structure 10 and the vibration damping structure 20 helps ensure the stability and accuracy of the machining process when machining main beams of different sizes and types.

[0062] Furthermore, the positioning and clamping structure 10 designed in this invention includes an axial limiting part 11 and a radial fixing part 12. The first linear drive mechanism of the radial fixing part 12 drives the third telescopic end 122 to extend and retract through the first fixed end 121, so that the third telescopic end 122 abuts against the upper part of the heliostat main beam 30, thereby achieving radial limiting of the main beam. The axial limiting part 11 includes two second linear drive mechanisms 112. The positioning support 32 on the heliostat main beam 30 is placed on the second support plate 111, and the two second linear drive mechanisms 112 are respectively located on both sides of the positioning support 32, with their fourth telescopic ends 114 extending towards each other, clamping the second support plate 111 and the positioning support 32 simultaneously, thereby achieving axial limiting of the main beam and restricting the rotation of the main beam around its central axis.

[0063] The positioning clamping structure 10 clamps the positioning heliostat main beam 30 (hereinafter referred to as the main beam) to prevent the heliostat main beam 30 from moving during processing, thereby ensuring the drilling accuracy. The existing technical solution is to clamp the heliostat main beam 30 with a three-jaw caliper or to squeeze the main beam from both radial sides to fix the main beam. Both of these fixing methods will squeeze the main beam and cause deformation. The fixing method in this application is to clamp the positioning support 32 of the heliostat main beam 30 with the second linear drive mechanism 112 and fix the main beam in conjunction with the third telescopic end 122, thereby fixing the main beam and reducing the radial deformation of the main beam.

[0064] Secondly, the vibration-damping structure 20 designed in this invention includes a mating part 21, an elastic component 22, and a fixed base 23; the bidirectional drive mechanism 211 extends and retracts to make the clamping block 212 fit tightly against the support beam 31, and the slide rail 232 adjusts the position of the mating part 21. The vibration during drilling is absorbed by the elastic component 22, eliminating the impact on accuracy caused by vibration; the function of the vibration-damping structure 20 is to lock the axial direction of the heliostat main beam 30 while giving the heliostat main beam 30 a certain buffer space in the axial direction, so as to ensure that other connecting components on the heliostat main beam 30 are not damaged or deformed while maintaining the heliostat main beam 30 in the preset state.

[0065] It should be noted that, in a specific embodiment of the present invention, before drilling begins, the pre-clamping and positioning of the heliostat main beam 30 by the heliostat main beam positioning and vibration damping assembly is the preset state of the heliostat main beam 30.

[0066] In summary, this invention provides a heliostat main beam positioning and vibration damping assembly and a drilling device for the heliostat main beam 30. By setting up a positioning clamping structure 10 and a vibration damping structure 20 to work together, this invention not only provides support, axial limiting, and radial limiting for the heliostat main beam 30, but also effectively controls the vibration of the heliostat main beam 30 and / or the main beam mounting components during subsequent processing, thereby ensuring the processing accuracy of subsequent steps. Specifically, the positioning clamping structure 10 includes an axial limiting part 11 and a radial fixing part 12. The axial limiting part 11 is used to axially limit the heliostat main beam 30, and the radial fixing part 12 is used to support the heliostat main beam 30 and radially limit it. The vibration damping structure 20 includes a mating part 21, an elastic component 22, and a fixed base 23. One end of the mating part 21 is slidably disposed in the fixed base 23, and the other end engages with the main beam mounting components on the heliostat main beam 30. When the heliostat main beam 30 or the main beam mounting component is machined, the vibration generated during machining is transmitted to the mating part 21 via the main beam mounting component. Since the axial limiting part 11 and the radial fixing part 12 respectively provide axial and radial constraints to the heliostat main beam 30, the vibration energy is ultimately transmitted to the main beam mounting component, thereby driving the mating part 21 to slide relative to the fixed base 23, causing the mating part 21 to compress or stretch the elastic component 22. The elastic component 22 absorbs the vibration energy through its own elastic deformation, effectively buffering the vibration generated during machining and reducing the impact of vibration on machining accuracy. By setting the anti-vibration structure 20, the vibration generated by the heliostat main beam 30 and / or the main beam mounting component during drilling can be effectively absorbed, ensuring the stability of the heliostat main beam 30 and its mounting components during machining. In practical applications, this heliostat main beam positioning anti-vibration component can significantly improve the stability of the heliostat main beam 30 during machining, especially in drilling operations, effectively reducing machining errors caused by vibration and improving product machining quality. Furthermore, the precise fit between the positioning and clamping structure 10 and the vibration damping structure 20 not only ensures the machining accuracy of the heliostat main beam 30 and / or the main beam mounting components, but also reduces abnormal stress on the axial limiting part 11 and the radial fixing part 12 during machining, helping to extend the service life of the equipment and reduce maintenance costs. The structural design of this component gives it good flexibility and adjustability, enabling it to adapt to different sizes and types of heliostat main beams 30, improving machining diversity and efficiency. This invention has a compact structure, is easy to assemble and maintain, and effectively solves the problems in the prior art where the heliostat main beam positioning device cannot effectively control machining vibration and where the heliostat main beam 30 is prone to radial deformation during machining, showing good prospects for widespread application.
