Description

Technical Field

[0001] The present invention relates to the technical field of information acquisition and measurement of historical cultural relics, and specifically to a laser-type information acquisition and measurement mechanism. Background Art

[0002] Measuring the contour and other information of the surface of historical cultural relics through an information acquisition and measurement mechanism can provide important reference basis for the later restoration and protection of historical cultural relics. Therefore, the use of an information acquisition and measurement mechanism in the restoration and protection of historical cultural relics is particularly important;

[0003] In the prior art, the patent with the application number "CN202110055925.6" and the patent name "A Non-contact Measuring Device and Measuring Method for the Surface Dimensions of Cultural Relics" discloses the following steps: Step 1, initialize the measuring device. Place the base of the non-contact measuring device beside the cultural relic to be measured, adjust the track to be approximately parallel to the surface of the cultural relic to be measured, and adjust the focal length of the laser beam of the micro infrared laser so that it focuses on the surface of the cultural relic to be measured; Step 2, one measurement process. Slide the micro infrared laser on the track so that the laser spot irradiates the starting point to be measured on the surface of the cultural relic to be measured. Press the "start button" of the microprocessor, and manually move the micro infrared laser. As it moves, the size displayed on the liquid crystal display interface changes continuously; make the laser spot move until it finally irradiates the ending point to be measured on the surface of the cultural relic to be measured, and press the "end button" of the microprocessor. The measured value displayed on the liquid crystal display interface is fixed and no longer changes, and this value is the measured value of this size measurement; Step 3, refresh the maximum measured value. The first display interface of the liquid crystal display is used to display the optimal measured value among multiple measurement results up to the current time, and the second display interface is used to display the current measurement result; Step 4, adjust the track angle. Adjust the track angle with the rotation joint as the axis, and repeat the operations in Step 2 and Step 3; Step 5, complete the measurement of the surface dimensions of the cultural relic. Repeat the operation in Step 4 until the maximum measured value is obtained. This measured value can only be measured when the track is parallel to the surface of the cultural relic to be measured, and the accuracy is the highest, which is the final measured size;

[0004] In the prior art, the patent with the application number "CN202111307797.6" discloses a patent named "A complex surface contour measurement system". The complex surface contour measurement system of the present invention realizes the unification of the coordinate system of the laser acquisition system and the coordinate system of the complex surface to be measured through a laser acquisition system covering a viewing angle range, a rotatable turntable, a motion mechanism for the turntable to move along the Y-axis, and a motion mechanism for the laser acquisition system to move along the Z-axis. And the controller controls one or more of the turntable, the first motion mechanism, and the second motion mechanism to perform corresponding compensation motions, realizing the automatic three-dimensional contour measurement of the entire complex surface and ensuring the measurement efficiency and measurement accuracy. Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value;

[0005] During the use of the above-mentioned laser-type information acquisition and measurement mechanism, after the laser acquisition system completes one acquisition while moving along the Z-axis, it is necessary to first move the laser acquisition system along the Z-axis in the reverse direction to reset it, and then use the motion mechanism to move the turntable along the Y-axis to adjust the position of the turntable and then perform a second acquisition on the laser acquisition system. This makes the adjustment operation relatively troublesome and cannot be adjusted synchronously. Therefore, when collecting and measuring information on historical relics later, it takes a long time, resulting in a slow efficiency of the laser-type information acquisition and measurement mechanism, and then affecting the work of collecting and measuring information on the contour of historical relics;

[0006] Therefore, we propose a laser-type information acquisition and measurement mechanism to solve the problems raised above. Summary of the Invention

[0019] Preferably, the toggle plate drives the rotating column to rotate through the toggle rod, and the length of the toggle rod is greater than the shortest distance between the toggle plate and the transmission rod.

[0020] Through the setting of the above structure, when the toggle rod rotates, it can push the toggle plate, so that the toggle plate drives the rotating column to rotate a certain angle.

[0021] Preferably, sliding grooves are symmetrically opened on the upper surface of the workbench, sliders are installed on the bottom surface of the support frame, and the sliders are slidably connected inside the sliding grooves;

[0022] A bidirectional lead screw is installed in a groove on the inner side of the front side of the workbench, the sliders are threadedly connected to both ends of the bidirectional lead screw, and the support frame forms a sliding structure with the workbench through the sliders.

[0023] Through the setting of the above structure, the stable sliding of the support frame is ensured.

[0024] Preferably, through grooves are opened inside the left and right sides of the main bracket;

[0025] The left and right sides of the main bracket are in concave-convex fit connection with the auxiliary brackets, a limiting column with a "T" shaped structure is installed above the auxiliary brackets, the lower end of the limiting column penetrates through the through groove, and the upper end diameter of the limiting column is greater than the width of the through groove.

[0026] With the above - mentioned structure, the cooperation between the limit posts and the through - grooves enables the main support to stably drive the two sub - supports to lift and lower together.

[0027] Preferably, a sub - receiving plate is installed by grooving on the upper surface of the main receiving plate. One end of the sub - receiving plate with an arc - shaped structure is provided with a connecting rod below it. The lower end of the connecting rod is inserted into the main receiving plate, and a connecting rope is wound around the outer side of the connecting rod.

[0028] A second scroll spring is nested on the outer side of the lower end of the connecting rod. The sub - receiving plate and the main receiving plate form a rotating structure through the connecting rod.

[0029] The upper surface of the main receiving plate and the upper surface of the sub - receiving plate are on the same horizontal plane.

[0030] With the above - mentioned structure, the cooperation between the main receiving plate and the rotatably deployed sub - receiving plate can increase the placement area for historical relics of larger sizes.

[0031] Preferably, the lower part inside the rotating column is of a hollow structure. A piston assembly is fitted inside the rotating column. A piston rod is installed above the piston assembly, and a mounting disc is installed above the piston rod.

[0032] The lower end of the connecting rope passes through the bottom surface of the main receiving plate and the upper part inside the rotating column and is connected to the upper surface of the mounting disc.

[0033] With the above - mentioned structure, when the mounting disc descends, it can simultaneously pull the lower ends of the four connecting ropes.

[0034] Preferably, a transfer frame is arranged outside the through - hole. The inside of the transfer frame is of a hollow structure. The transfer frame is installed in a groove opened in the workbench. The lower outer side of the rotating column is connected to the upper and lower inner walls of the transfer frame through two sealing bearings.

[0035] Through - holes are equidistantly arranged on the lower outer side of the rotating column, and the through - holes are arranged below the piston assembly.

[0036] The space inside the transfer frame is connected to the space inside the rotating column through the through - holes, and a flow - through pipe is installed through the front end of the transfer frame.

[0037] With the above - mentioned structure, the cooperation of the transfer frame will not affect the later rotation work of the rotating column and is also convenient for injecting or extracting the gas inside the rotating column.

[0038] Preferably, the middle position of the bidirectional lead screw is connected to the lower vertical adjusting rod through a bevel gear set. The vertical adjusting rod is installed inside the front of the workbench, and threads are provided on the surface of the vertical adjusting rod.

[0041] The rear side of the air storage bag is connected to the front end of the flow tube.

[0042] By setting the above structure, when the volume of the air storage bag expands, part of the gas in the rotating column can be extracted through the circulation pipe, so that the piston assembly in the rotating column moves downward.

[0043] Compared with the prior art, the invention has the following beneficial effects: the laser information collection and measurement mechanism, through the coordinated use of the toggle lever and the toggle plate, facilitates the upward movement of the measuring head to reset, and at the same time, the measurement area of ​​the historical relics can be rotated and replaced through the structure, which is convenient to operate and saves time, thereby improving the measurement efficiency of the laser information collection and measurement mechanism. The specific contents are as follows:

[0044] When the transmission rod rotates, the fan-shaped gear meshes with the driven gear to drive the threaded rod to rotate, so that the threaded rod drives the measuring head to move downward through the main bracket and the auxiliary bracket, so that the laser profile sensor in the measuring head can measure the contour of the surface of the historical relic well. When a measurement is completed, the fan-shaped gear rotates to be out of mesh with the driven gear. At this time, the threaded rod rotates in the opposite direction through the first vortex spring, so that the main bracket and the auxiliary bracket drive the measuring head to move upward and reset. At the same time, the transmission rod continues to rotate to drive the toggle rod to push the toggle plate at the corresponding position, so that the toggle plate drives the rotating column and the main receiving plate to rotate, so that the measuring head moves upward and resets, and the measuring area of ​​the historical relic can be rotated and replaced through this structure. The operation is convenient and time-saving, thereby improving the measurement efficiency of the laser information acquisition and measurement mechanism.

[0045] By sliding the slider in the slide slot, the distance between the two measuring heads can be adjusted, so it is convenient to place historical relics of larger sizes on the main receiving plate, so that the entire laser information collection and measurement mechanism can measure historical relics of different sizes, thereby increasing the scope of use of the entire laser information collection and measurement mechanism;

[0046] Furthermore, the sliding of the limit column in the through groove facilitates the sliding connection between the main bracket and the auxiliary bracket, so that the distance between the two auxiliary brackets can be well adjusted, so that the two auxiliary brackets can stably support the two measuring machine heads;

[0047] By rotating the auxiliary receiving plate with the connecting rod as the center, the four auxiliary receiving plates can be used in coordination with the main receiving plate, so as to support and place historical relics of larger size well, thereby improving the stability of placing historical relics of larger size;

[0048] Furthermore, while the two-way screw rotates to drive the two measuring heads to move outward, the two-way screw drives the vertical adjustment rod to rotate through the bevel gear set, so that the adjustment plate drives the extrusion plate to move upward to remove the extrusion force on the air storage bag. The volume expansion of the air storage bag draws out the gas in the rotating column through the flow tube, so that the piston assembly in the rotating column pulls the connecting rope to move downward, and then the four auxiliary receiving plates can be controlled to rotate outward and unfold at the same time, so as to facilitate the stable placement of larger historical relics in the later stage.

Detailed implementation manner

[0061] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0062] Please refer to Figures 1-11 , the present invention provides the following technical solutions:

[0063] Embodiment 1: When the laser-type information acquisition and measurement mechanism in this embodiment is used, the efficiency of acquiring and measuring the contour information of historical cultural relics can be improved, and the measurement time is shortened. Specifically, refer to the attached Figures 1-4 shown, which includes a workbench 1 and a display 4 installed above the right side of the workbench 1; a main receiving plate 5 is installed above the workbench 1, and a rotating column 13 is installed on the bottom surface of the main receiving plate 5. The lower part of the rotating column 13 is inserted into the workbench 1 for rotational connection; two support frames 2 are symmetrically installed on the upper surface of the workbench 1 with the center of the main receiving plate 5 as the vertical center line, and a measuring head 3 is arranged in the support frame 2;

[0064] A threaded rod 6 is installed through the inside of the workbench 1, and the upper outer side of the threaded rod 6 is threadedly connected with a main bracket 7; the two sides of the main bracket 7 are slidably connected with sub-brackets 8, and the front end of the sub-bracket 8 is inserted into the groove on the rear side of the support frame 2 and connected with the measuring machine head 3; a driven gear 61 is installed on the lower outer side of the threaded rod 6, and a transmission rod 12 is installed in the workbench 1 on the front side of the threaded rod 6, and the bottom end of the transmission rod 12 is connected to the motor in the workbench 1; the outer side of the transmission rod 12 is sequentially installed with a fan gear 121 and a toggle rod 122 from bottom to top, and the fan gear 121 is meshed and connected with the driven gear 61; the upper outer side of the rotating column 13 is evenly spaced and the toggle plate 18 is installed, and the toggle rod 122 is set on the left side of the toggle plate 18. A support rod 201 is installed in the support frame 2, and the outer side of the support rod 201 is slidably connected with the measuring machine head 3; the outer side of the threaded rod 6 is installed with a first vortex spring 62. The toggle plate 18 drives the rotating column 13 to rotate through the toggle rod 122, and the length of the toggle rod 122 is greater than the shortest distance between the toggle plate 18 and the transmission rod 12;

[0065] First, place the historical relics to be measured in the central area of ​​the main receiving plate 5, then start the motor at the bottom end of the transmission rod 12, the motor drives the transmission rod 12 to rotate, and the transmission rod 12 drives the fan gear 121 and the toggle rod 122 to rotate when rotating, then the fan gear 121 starts to mesh with the driven gear 61, and then the fan gear 121 drives the driven gear 61 to rotate, at this time the driven gear 61 drives the threaded rod 6 to rotate, and when the threaded rod 6 rotates, the first vortex spring 62 accumulates force, and at the same time, when the threaded rod 6 rotates, it drives the main bracket 7 and the auxiliary bracket 8 on the upper outer side to move downward together, at this time, one end of the auxiliary bracket 8 drives the measuring head 3 to the lower end, and at this time, one end of the measuring head 3 is on the support The outer side of the support rod 201 in the support frame 2 slides, thereby ensuring that the measuring head 3 moves downward stably. During the movement of the measuring head 3 from top to bottom, the laser profile sensor in the measuring head 3 starts to emit a laser beam, so that the laser beam is irradiated on the corresponding historical cultural relics, and then the laser profile sensor transmits this signal to the computer, and the computer finally restores the contour information and roughness information of the historical cultural relics and displays them in a curve graph, which can be viewed through the display 4. The analysis tools provided by the software can perform various parameter analyses on the contour and roughness. Since this part is a prior art, it will not be introduced in detail here. Therefore, the laser type information collection and measurement mechanism is very good at collecting and measuring the contour information of historical cultural relics;

[0066] When the sector gear 121 rotates to the point where it is not meshed with the driven gear 61, the central processing module controls the closing of the measuring head 3, and then the accumulated force of the first vortex spring 62 automatically drives the threaded rod 6 to rotate in the opposite direction, so that the threaded rod 6 drives the main bracket 7 to move upward, as shown above, so that the measuring head 3 moves upward and resets, and at the same time, the transmission rod 12 continues to drive the sector gear 121 and the toggle rod 122 to rotate. At this time, the toggle rod 122 rotates to push the toggle plate 18 at the corresponding position, as shown in the attached figure. Figure 11 As shown, the toggle plate 18 drives the rotating column 13 to rotate at a certain angle, and the rotating column 13 drives the main receiving plate 5 to rotate at a certain angle, so that the main receiving plate 5 drives the historical relics placed on it to rotate at a certain angle with the center of the main receiving plate 5 as the center, so as to facilitate the replacement of the measurement area of ​​the historical relics;

[0067] Then the sector gear 121 continues to rotate until it meshes with the driven gear 61, and similarly as shown above, the measuring head 3 descends to perform the secondary measuring area for measuring work. By repeating the operation, the historical relics can be quickly measured in all directions without the need for the staff to manually rotate the historical relics to adjust the measuring area, and the operation is convenient;

[0068] Embodiment 2: The laser information collection and measurement mechanism in this embodiment can well adjust the distance between the two measuring heads 3, so that the two measuring heads 3 can measure historical relics of different sizes. Figures 4-5 As shown, the upper surface of the workbench 1 is symmetrically provided with a slide groove 9, the bottom surface of the support frame 2 is installed with a slider 202, and the inside of the slide groove 9 is slidably connected with the slider 202; the front side surface of the workbench 1 is internally grooved with a bidirectional screw rod 10, and the slider 202 is threadedly connected to the outer sides of both ends of the bidirectional screw rod 10, and the support frame 2 forms a sliding structure with the workbench 1 through the slider 202. The left and right sides of the main bracket 7 are provided with a through groove 71; the left and right sides of the main bracket 7 are connected with a sub-bracket 8 in a concave-convex manner, and a limiting column 81 in a "T" shape is installed above the sub-bracket 8, the lower end of the limiting column 81 passes through the through groove 71, and the upper end diameter of the limiting column 81 is larger than the width of the through groove 71;

[0069] When it is necessary to measure large-sized historical relics, manually rotate the left end of the bidirectional lead screw 10 at this time. At this time, the rotation of the bidirectional lead screw 10 drives the slider 202 connected by the outer thread to move outward in the chute 9. Therefore, the slider 202 drives the support frame 2 to move outward. At this time, the measuring head 3 in the support frame 2 drives the auxiliary support 8 to move outward. At this time, the limit post 81 on the outer side of one end of the auxiliary support 8 slides in the through groove 71, so as to ensure the stable sliding of the auxiliary support 8. Therefore, it is convenient to stably adjust the distance between the two measuring heads 3, improving the use range of the laser-type information acquisition and measurement mechanism. Then, as shown in Embodiment 1, carry out the information acquisition and measurement work;

[0070] Embodiment 3: On the basis of Embodiment 2, the supporting area of the main bearing plate 5 can be increased to facilitate the stable placement of large-sized historical relics on the main bearing plate 5. Specifically, refer to the appendix Figures 7-10 As shown, a secondary bearing plate 11 is installed in a groove on the upper surface of the main bearing plate 5. One end of the arc-shaped secondary bearing plate 11 is provided with a connecting rod 111 below it. The lower end of the connecting rod 111 is inserted into the main bearing plate 5, and a connecting rope 113 is wound around the outer side of the connecting rod 111;

[0071] A second scroll spring 112 is nested on the outer side of the lower end of the connecting rod 111. The secondary bearing plate 11 forms a rotating structure with the main bearing plate 5 through the connecting rod 111; the upper surface of the main bearing plate 5 and the upper surface of the secondary bearing plate 11 are on the same horizontal plane. The lower part inside the rotating column 13 is hollow. A piston assembly 17 is fitted inside the rotating column 13. A piston rod 172 is installed above the piston assembly 17, and a mounting plate 171 is installed above the piston rod 172; the lower end of the connecting rope 113 passes through the bottom surface of the main bearing plate 5 and the upper part inside the rotating column 13 and is connected to the upper surface of the mounting plate 171. A transfer frame 14 is arranged outside the through hole 131. The inside of the transfer frame 14 is hollow. The transfer frame 14 is installed in a groove opened in the workbench 1. The lower outer side of the rotating column 13 is connected to the upper and lower inner walls of the transfer frame 14 through two sealed bearings. The sum of the heights of the two sealed bearings is less than the height of the transfer frame 14. The inner wall of the transfer frame 14 is an open structure;

[0072] Through holes 131 are equidistantly arranged on the outer side below the rotating column 13, and the through holes 131 are arranged below the piston assembly 17; the space inside the transfer frame 14 is communicated with the space inside the rotating column 13 through the through holes 131, and a flow pipe 141 is installed through the front end of the transfer frame 14. The middle position of the bidirectional lead screw 10 is connected to the vertical adjusting rod 16 below through a bevel gear set. The vertical adjusting rod 16 is installed inside the front of the workbench 1, and threads are provided on the surface of the vertical adjusting rod 16; a regulating plate 161 with a "7" - shaped structure is thread - connected to the outside of the vertical adjusting rod 16, and a pressing plate 162 is installed below the regulating plate 161. An air storage airbag 15 is installed in a groove inside the front of the workbench 1, an air inlet pipe is installed on the front side of the air storage airbag 15, and the pressing plate 162 is arranged above the air storage airbag 15; the rear side of the air storage airbag 15 is connected to the front end of the flow pipe 141;

[0073] When the bidirectional lead screw 10 rotates, it drives the vertical adjusting rod 16 below to rotate through the bevel gear set in the middle position. Since the vertical adjusting rod 16 and the regulating plate 161 are thread - connected, the rotation of the vertical adjusting rod 16 drives the regulating plate 161 to move upward. At this time, the regulating plate 161 with a "7" - shaped structure drives the pressing plate 162 to move upward. At this time, the pressing plate 162 does not squeeze the air storage airbag 15, and then the volume of the air storage airbag 15 automatically expands. At this time, through the cooperation of the air storage airbag 15 and the transfer frame 14 with the flow pipe 141, the gas in the rotating column 13 is pumped out through the through holes 131. At this time, the gas in the rotating column 13 decreases, causing the piston assembly 17 in the rotating column 13 to move downward. Then the piston assembly 17 drives the mounting disc 171 and the piston rod 172 to move downward. At this time, the mounting disc 171 pulls the four connecting ropes 113 downward, causing the upper ends of the four connecting ropes 113 to drive the corresponding connecting rods 111 to rotate. At this time, the connecting rods 111 drive the auxiliary bearing plates 11 to rotate and unfold outward, as shown in the appendix Figure 10 As shown, at this time, the second scroll spring 112 stores energy. Therefore, through the cooperation of the four auxiliary bearing plates 11 that rotate and unfold outward and the main bearing plate 5, the bearing area for larger - sized historical relics can be increased. Therefore, the laser - type information acquisition and measurement mechanism can stably place larger - sized historical relics, facilitating the subsequent information acquisition and measurement work on larger - sized historical relics, thus completing a series of work.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
