Description

Technical Field

[0001] This invention relates to the field of measurement technology, and more specifically, to a lofting and marking mechanism and a lofting and marking method. Background Technology

[0002] In the final assembly of a fusion reactor main unit, the accuracy requirements for the collimation and positioning of components are very high, and the requirements for critical components are even higher. Furthermore, due to the significant weight of most components, high-precision layout and marking are typically required before placement to reduce post-placement adjustments. Existing layout solutions use a laser tracker paired with a hollow target base for single-point layout. First, the laser tracker measures the reference grid to position itself. Then, the position of the target ball on the hollow target base is monitored and adjusted. After the position is determined, the target base is manually pressed down, the target ball is removed, and a tungsten carbide marking pen is used to draw the line on the hollow target base. This method can only locate one point at a time, which is unsuitable for the layout requirements of hundreds of points in a single fusion reactor main unit assembly. Moreover, because the target base position cannot be monitored in real time during marking, the accuracy of the marking is uncontrollable. Summary of the Invention

[0007] Optionally, the first adjustment assembly further includes a locking member; the locking member is movably connected to the frame and located at the end of the abutment rod away from the adjustment member; when the adjustment member adjusts the rotating assembly to a specified position, the locking member is used to move relative to the frame to abut the abutment rod so as to clamp the abutment rod together with the adjustment member.

[0008] Optionally, the lofting and marking mechanism further includes a second adjustment component, which includes at least four adjustment knobs. All four adjustment knobs are located on the frame, and at least three of the adjustment knobs are arranged in a triangular pattern.

[0024] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0025] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0026] Please refer to the following: Figures 1 to 6 This embodiment provides a lofting and marking mechanism, which can be applied to the alignment and positioning of components during the final assembly of a fusion mainframe to improve the accuracy and efficiency of alignment and positioning. This lofting and marking mechanism not only meets the high-precision lofting and marking requirements of ultra-large components, but also reduces the number of lofting and positioning operations, significantly improving the efficiency of lofting and marking during the alignment and installation of ultra-large equipment, and addressing the technical problem of low efficiency in marking operations in existing technologies.

[0027] In this embodiment, the lofting and marking mechanism includes a frame 1, a rotating component 2, a first measuring component 6, a second measuring component, a marking component 7, and a first adjusting component 4. One end of the rotating component 2 is rotatably connected to the frame 1. The first measuring component 6 is located at one end of the rotating component 2, and its center is located on the straight line of the rotation axis of the rotating component 2; that is, after the rotating component 2 rotates, the first measuring component 6 remains at the rotation center of the rotating component 2. The second measuring component is located at the other end of the rotating component 2. Both the first and second measuring components are used for tracking and identification by a laser tracker for positioning and measurement. In other words, the lofting and marking mechanism provided in this embodiment is applied to lofting and marking operations using a laser tracker. The marking component 7 is connected to the rotating component 2 and has multiple slots for marking lines; after the marking component 7 completes its positioning following the rotating component 2, a marking pen such as a tungsten carbide pen can be used to draw lines. The first adjusting component 4 is located on the frame 1 and abuts against the rotating component 2, used to drive the rotating component 2 to rotate under external force.

[0028] As described above, when performing the layout and marking operation, the layout and marking mechanism can first be placed in the area to be marked, and the first measuring component 6 and the second measuring component can be roughly adjusted to their approximate positions. Then, while ensuring that the frame 1 is level overall, the position of the first measuring component 6 can be finely adjusted to the designated position, and the frame 1 can be fixed in the area to be marked. With the layout and marking mechanism remaining stable, the first adjusting component 4 drives the rotating component 2 to rotate, causing the second measuring component to move to the designated position, thus achieving layout positioning. Then, lines are drawn through the grooves on the marking component 7 to form multiple points. Connecting the lines of multiple points completes the layout and marking operation. In particular, by coarsely adjusting the positions of the first measuring component 6 and the second measuring component, and then finely adjusting the positions of the first measuring component 6 and the second measuring component, multiple points are determined based on two adjustments. Finally, connecting the multiple points can form more points, which can be applied to the layout requirements of hundreds of points in a single fusion reactor main assembly, improving the technical problem of low positioning and marking efficiency in the prior art.

[0029] It should be noted that, in this embodiment, Spatial Analyzer software can be used to construct the center points of the first measuring component 6 and the second measuring component. Specifically, the center points of the first measuring component 6 and the second measuring component can be constructed based on the center distance between them and a preset drawing position. Furthermore, after measuring the reference network using a laser tracker and completing its own positioning, measurement point monitoring can be enabled using Spatial Analyzer software to simultaneously monitor the positions of the first measuring component 6 and the second measuring component. Of course, generally only the horizontal positions of the first measuring component 6 and the second measuring component need to be monitored.

[0030] It should be understood that in other embodiments, other software besides Spatial Analyzer software that can be used to construct the center point of the first measurement component 6 and the second measurement component and to perform position monitoring of the first measurement component 6 and the second measurement component can also be used.

[0031] In this embodiment, the first adjusting component 4 includes an adjusting member 301, a supporting component, and an elastic member 404. The adjusting member 301 is movably disposed on the frame 1 and abuts against the rotating component 2. The adjusting member 301 is used to drive the rotating component 2 to rotate under the action of an external force. The supporting component abuts against the rotating component 2 and, together with the adjusting member 301, clamps the rotating component 2. The elastic member 404 is connected to the supporting component and is used to generate elastic deformation when the rotating component 2 pushes the supporting component. The adjusting member 301 can be a rotating adjusting structure such as an adjusting screw; alternatively, a threaded fine-tuning mechanism can be used instead of an adjusting screw. In this embodiment, an L-shaped base 401 is provided on the frame 1. The adjusting member 301 is movably connected to the base 401, and the portion passing through the base 401 abuts against the rotating component 2.

[0032] When the rotating component 2 is driven by the first adjusting component 4, the adjusting component 301 can be driven by an external force. Under the action of the external force, the adjusting component 301 drives the rotating component 2 to move, thereby realizing the rotation of the rotating component 2. At the same time, the rotating component 2 pushes the supporting component. Based on the elastic deformation of the elastic component 404, the rotating component 2 can be stably supported on the adjusting component 301, so as to ensure that the rotating component 2 and the adjusting component 301 can move synchronously and ensure the accuracy of adjustment.

[0033] Furthermore, the supporting assembly includes a fixed base 402, a supporting rod 403, and a limiting member 405. The fixed base 402 is fixedly connected to the frame 1, the supporting rod 403 passes through the fixed base 402 and can move relative to the fixed base 402, and one end of the supporting rod 403 abuts against the adjusting member 301. The limiting member 405 is fixedly disposed on the supporting rod 403. An elastic member 404 is disposed at the end of the supporting rod 403 away from the adjusting member 301, and one end of the elastic member 404 abuts against the limiting member 405, and the other end abuts against the fixed base 402. When the rotating assembly 2 moves with the adjusting member 301, the rotating assembly 2 pushes the supporting rod 403 to move, and the limiting member 405 moves with the supporting rod 403 to compress the elastic member 404. Under the action of the elastic member 404, the supporting rod 403 can be stably abutted against the rotating assembly 2.

[0034] Optionally, in this embodiment, the fixing seat 402 has a U-shaped structure, and the abutment rod 403 passes through two vertical parts on the fixing seat 402. The limiting member 405 is located inside the opening of the U-shaped structure, and the elastic member 404 is sleeved on the abutment rod 403 and located inside the opening of the U-shaped structure. One end of the elastic member 404 abuts against the limiting member 405, and the other end abuts against the inner wall of the opening of the U-shaped structure.

[0035] Furthermore, the first adjustment component 4 also includes a locking member; the locking member is movably connected to the frame 1 and located at the end of the abutment rod 403 away from the adjustment member 301; when the adjustment member 301 adjusts the rotating component 2 to a designated position, the locking member is used to move relative to the frame 1 to abut the abutment rod 403 so as to clamp the abutment rod 403 together with the adjustment member 301. After the first measuring component 6 and the second measuring component are finely adjusted to the designated positions, the abutment rod 403 can be clamped and fixed by the locking member and the adjustment member 301, ensuring the stability of the positions of the first target ball 601 and the second target ball during the line drawing process, ensuring real-time monitoring of the target position during line drawing, and ensuring the accuracy of the line drawing.

[0036] Similarly, when the rotating component 2 needs to be freely adjusted, the locking member must first release its grip on the abutment rod 403 to ensure that the rotating component 2 can rotate freely. After the adjustment of the rotating component 2 is completed, the locking member is used to fix the abutment rod 403, thereby fixing the rotating component 2.

[0037] In this embodiment, the lofting and drawing mechanism further includes a second adjustment component 3, which includes at least four adjustment knobs 301. All four adjustment knobs 301 are located on the frame 1, and at least three of the adjustment knobs 301 are arranged in a triangular pattern, meaning that the positions of the at least three adjustment knobs 301 can form a triangle when connected in pairs. The adjustment knobs 301 are used to adjust the placement posture of the frame 1 to be horizontal. In this embodiment, the frame 1 is generally square, and the adjustment knobs 301 are distributed at different positions on the frame 1. The posture of the frame 1 is adjusted using three of the adjustment knobs 301 until the entire frame 1 is placed horizontally, thereby ensuring that the rotating component 2 is placed horizontally, which helps improve the accuracy of the lofting and drawing. After the frame 1 is adjusted to be horizontal, it can be fixed using the remaining adjustment knobs 301.

[0038] In this embodiment, the layout and marking mechanism further includes a level 302, which is mounted on the rotating assembly 2 and located between the first measuring assembly 6 and the second measuring assembly. During adjustment using the adjusting knob 301, the level 302 can be used to determine whether the frame 1 and the rotating assembly 2 are in a horizontal position. The level 302 can be a three-part bubble level.

[0039] In this embodiment, the first measuring component 6 includes a first target holder 602 and a first target ball 601. The first target holder 602 is disposed on the rotating component 2, and the first target ball 601 is disposed on the first target holder 602. The geometric center of the first target ball 601 is located on the straight line of the rotation center axis of the rotating component 2. The second measuring component includes a second target holder and a second target ball. The second target holder is disposed on the rotating component 2, and the second target ball is disposed on the second target holder. The laser tracker can perform positioning measurements using the first target ball 601 and the second target ball.

[0040] Additionally, the rotating assembly 2 includes a crossbeam 201, a connecting block 206, and multiple first trays 204. One end of the crossbeam 201 is rotatably connected to the frame 1 via a tapered roller bearing 203. First trays 204 are provided at both ends of the crossbeam 201, supporting the first measuring component 6 and the second measuring component. A second tray 205 is also provided in the middle of the crossbeam 201, supporting the level 302. The connecting block 206 is located on the bottom side of the middle section of the crossbeam 201, connecting the marking component 7. Furthermore, a positioning block 202 is provided at the end of the crossbeam 201 away from the tapered roller bearing 203, and the adjusting member 301 transmits power to the rotating assembly 2 by abutting against the positioning block 202. Fastening screws 303 can be provided on both the first tray 204 and the second tray 205. Taking the first tray 204 as an example, the fastening screws 303 can pass through the outer wall of the first tray 204 and extend into the interior of the first tray 204 to fix the first measuring component 6, the second measuring component and the level 302.

[0041] In this embodiment, the drawing component 7 includes a first ruler and a second ruler, which are perpendicular to each other. Both the first and second rulers have multiple L-shaped grooves. Notably, the first and second rulers together form a cross shape, with multiple L-shaped grooves on both. These grooves can be divided into multiple groups, with each group containing four grooves. Two grooves are located on the first ruler, and the other two on the second ruler. The four grooves are distributed at the four corners of a rectangle; in other words, the extensions of the four grooves connect to form a rectangle. It should be noted that, generally, the lengths of the first and second rulers can extend beyond the frame 1. Preferably, the length of the first and second rulers extending beyond the frame 1 is no more than twice the length of the portion that does not extend beyond.

[0042] In this embodiment, the lofting and drawing mechanism further includes a magnetic base 5, which is disposed on the frame 1; the magnetic base 5 is used to fix the frame 1 at the drawing position. Generally, the magnetic base 5 can be used to fix the frame 1 in the magnetic area; while when drawing lines in the non-magnetic area, the magnetic base 5 can be replaced with a vacuum suction cup or other detachable fixing device.

[0043] In summary, when performing the layout and marking operation, this mechanism can first be placed in the area to be marked, and the first measuring component 6 and the second measuring component can be roughly adjusted to their approximate positions. Then, while ensuring the frame 1 is level, the position of the first measuring component 6 can be finely adjusted to the designated position, and the frame 1 can be fixed in the area to be marked. With the layout and marking mechanism remaining stable, the first adjusting component 4 drives the rotating component 2 to rotate, causing the second measuring component to move to the designated position, thus achieving layout positioning. Then, lines are drawn through the grooves on the marking component 7 to form multiple points. Connecting these multiple points completes the layout and marking operation. By coarsely adjusting the positions of the first measuring component 6 and the second measuring component, and then finely adjusting them, multiple points are determined based on these two adjustments. Finally, connecting these multiple points allows for the formation of even more points, making it suitable for the layout requirements of hundreds of points in a single fusion reactor main assembly, thus improving the low efficiency of positioning and marking in existing technologies. Furthermore, after the first measuring component 6 and the second measuring component are finely adjusted to the designated positions, the holding rod 403 can be clamped and fixed by the locking member and the adjusting member 301 to ensure that the positions of the first target ball 601 and the second target ball are stable during the line drawing process, and to ensure that the target position is monitored in real time during the line drawing, thus ensuring the accuracy of the line drawing.

[0044] Based on the lofting and drawing mechanism provided above, this embodiment also provides a lofting and drawing method, which is applied to the above lofting and drawing mechanism and can improve the problem of low efficiency in the prior art.

[0045] Please refer to the following: Figure 6 and Figure 7 The methods for lofting and drawing lines include: S1. Place frame 1 in the drawn area and roughly adjust the positions of the first measuring component 6 and the second measuring component.

[0046] It is worth noting that after placing frame 1 in the drawn area, the center points of the first target ball 601 and the second target ball can be pre-constructed in the Spatial Analyzer software based on the center distance between the first target ball 601 and the second target ball and the position of the drawn area. Then, the reference network is measured using a laser tracker to complete its self-positioning. After completing the preparation work, measurement point monitoring can be enabled in the Spatial Analyzer software to monitor the positions of the first target ball 601 and the second target ball. Afterwards, the first measurement component 6 and the second measurement component are placed in their approximate positions.

[0047] S2. After fine-tuning the first measuring component 6 to the designated position, fix the frame 1 in the drawn area.

[0048] Before step S1, after placing the first measuring component 6 and the second measuring component in their approximate positions, the overall posture of the frame 1 is adjusted by adjusting the knob 301 until the frame 1 can be judged to be horizontal by the level 302. Then, the first measuring component 6 is finely adjusted, and after the adjustment is in place, the frame 1 is fixedly installed by the magnetic base 5.

[0049] S3. After adjusting the rotating component 2 to a horizontal position, control the first adjusting component 4 to output power to adjust the second measuring component to the specified position.

[0050] The method of controlling the output power of the first adjusting component 4 can be manual, such as manually rotating the adjusting member 301 to drive the rotating component 2. Alternatively, a motor, hydraulic mechanism, or a motor combined with a worm gear structure can be used to drive the adjusting member 301, thereby driving the rotating component 2.

[0051] It is worth noting that before driving the adjustment component 301, it is essential to ensure that the locking component is released from the abutment rod 403, otherwise the instrument will inevitably be damaged.

[0052] S4. Fix the rotating component 2 and draw lines from the groove to obtain multiple points.

[0053] After the position of the rotating component 2 is precisely adjusted by the first adjustment component 4, that is, after the second measuring component is moved to the designated position, the locking member is used to lock and reinforce the abutment rod 403, thereby improving the overall positional stability of the rotating component 2, the first target ball 601, and the second target ball, and reducing the loss of measurement accuracy caused by manual pressing of the target ball in the prior art.

[0054] After fixing the rotating component 2, you can use a drawing tool such as a tungsten carbide pen to draw lines through the groove and in the drawing area to obtain multiple points.

[0055] S5. Use a straight ruler to draw lines connecting multiple points to complete the layout and line drawing operation.

[0056] By connecting multiple points, more points can be obtained, thereby improving the efficiency of layout and positioning.

[0057] like Figure 6 As shown, after step S4, eight points containing L-shaped imprints can be obtained (e.g. Figure 6 The attached diagram in the middle shows a multi-grid graphic (as shown in the image). By extending and connecting the lines of the L-shaped imprint, a multi-grid graphic can be obtained (e.g., ...). Figure 6 (See the attached diagram on the right), and the intersections of the multi-grid graphic complete the precise layout of multiple points.

[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
