Description

Technical Field

[0001] This utility model relates to the field of measurement, specifically a multi-station measurement bracket. Background Technology

[0002] Currently, when using a 3D optical scanner to measure blade products, it is usually necessary to affix markers to the blades so that the scanner software can accurately stitch together 3D images taken from different locations. Depending on the blade size, 15 to 50 markers are needed for each measurement. If multiple products are being measured, multiple blades need to be marked and measured sequentially. After measurement, these markers also need to be removed from the blades. Manually affixing and removing markers is time-consuming, reducing measurement efficiency and accuracy.

[0003] Therefore, a multi-station measurement bracket is provided to solve the above problems. Utility Model Content

[0004] The technical problem solved by this invention is how to improve measurement efficiency and accuracy.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multi-station measuring bracket, which further includes a base, a frame, a first clamping component and a second clamping component. The base is fixedly connected to the frame. A plurality of first measuring stations and a plurality of second measuring stations are distributed at intervals on the frame. A first clamping component is fixed in each first measuring station and a second clamping component is fixed in each second measuring station. A plurality of pasting areas are provided on the frame around each first measuring station and each second measuring station.

[0006] The beneficial effects of this utility model are: the base is fixedly installed on the turntable of the three-dimensional optical scanner, and multiple marker points and multiple code points are pasted alternately on the frame around each first measurement station and each second measurement station. The three-dimensional optical scanner collects the positions of multiple marker points and multiple code points and establishes a reference point frame.

[0007] Subsequently, multiple blades are clamped onto multiple first clamping assemblies and multiple second clamping assemblies, respectively. Driving the 3D optical scanner turntable to rotate causes the blades within the base and frame to rotate as well. The 3D optical scanner can simultaneously acquire images of the blades at different angles within one measurement station, as well as the positions of markers and coded points on the frame surrounding that measurement station. It then automatically stitches the acquired blade images together with the corresponding positions on the reference frame, completing the measurement of the blade and improving detection accuracy and efficiency.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the frame includes a first support plate, a second support plate, a third support plate, and a plurality of support columns. The base is fixedly connected to the first support plate. One end of the plurality of support columns is spaced apart on the first support plate, and the other end of the support columns passes through the second support plate and the third support plate in sequence, and is detachably connected to the second support plate and the third support plate respectively. Each first clamping assembly is located between two adjacent support columns and is detachably connected to the first support plate. Each second clamping assembly is located between two adjacent support columns and is detachably connected to the second support plate.

[0010] The beneficial effects of adopting the above-mentioned further solution are: multiple marking points and multiple coding points can be pasted alternately on the outer surfaces of the first support plate, the second support plate, the third support plate and multiple support columns, which facilitates the establishment of a reference point framework and improves the detection accuracy.

[0011] Furthermore, the support column is a hexagonal prism.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the support column has multiple surfaces, and multiple marking points and multiple coding points can be pasted on each surface in an alternating manner, thereby increasing the accuracy of the measurement.

[0013] Furthermore, it also includes a first fixing block, with one end of the support column fixedly connected to one end of each of the two first fixing blocks on both sides, and the other end of the first fixing block fixedly connected to the first support plate.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the two first fixing blocks are located on both sides of one end of the support column, which can increase the stability of the support column and prevent the support column from shifting during rotation, thus affecting the measurement quality.

[0015] Furthermore, it also includes a second fixing block, wherein the two sides of the middle part of the support column are respectively fixedly connected to one end of the two second fixing blocks, and the other end of the second fixing block is fixedly connected to the second support plate.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the two second fixing blocks are located on both sides of the middle of the support column, which can increase the stability of the support column and prevent the support column from shifting during rotation, thus affecting the measurement quality.

[0017] Furthermore, both the first fixing block and the second fixing block are right-angled triangular plates.

[0018] Furthermore, the first clamping assembly includes a first chassis, a first support platform, a first clamping block, a second clamping block, a first lead screw, and a first handle. The first chassis is fixedly connected to the first support plate, and the first support platform is fixedly mounted on the first chassis. The first lead screw is installed inside the first support platform, with one end of the first lead screw rotatably connected to one end of the first support platform. The other end of the first lead screw extends out of the other end of the first support platform and is fixedly connected to the first handle. The first clamping block is sleeved on the outside of the first lead screw and is threadedly connected to the first lead screw. The first clamping block is slidably connected to the first support platform. The second clamping block is sleeved on the outside of the first lead screw and is fixedly connected to one end of the first support platform.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the tenon of the blade is placed in the first clamping block and the second clamping block on the first support platform, and the first handle is rotated to drive the first clamping block to move along the length direction of the first screw until the first clamping block and the second clamping block clamp the tenon of the blade, thus completing the clamping of the blade to be tested.

[0020] Furthermore, the second clamping assembly includes a second chassis, a second support platform, a third clamping block, a fourth clamping block, a second lead screw, and a second handle. The second chassis is fixedly connected to the second support plate, and the second support platform is fixed on the second chassis. The second lead screw is installed inside the second support platform, with one end of the second lead screw rotatably connected to one end of the second support platform, and the other end of the second lead screw extending out of the other end of the second support platform and fixedly connected to the second handle. The third clamping block is sleeved on the second lead screw and threadedly connected to the second lead screw. The third clamping block is slidably connected to the second support platform. The fourth clamping block is sleeved on the second lead screw and fixedly connected to one end of the second support platform.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the tenon of the blade is placed in the third and fourth clamping blocks on the second support platform, and the second handle is rotated to drive the third clamping block to move along the length of the second screw until the third and fourth clamping blocks clamp the tenon of the blade, thus completing the clamping of the blade to be tested.

[0022] Furthermore, multiple second measurement stations are located above multiple first measurement stations, and the multiple second measurement stations are arranged horizontally at intervals, as are the multiple first measurement stations.

[0023] Furthermore, the number of the plurality of second measurement stations is the same as the number of the plurality of first measurement stations. Attached Figure Description

[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] like Figures 1-7 As shown, this embodiment provides a multi-station measuring bracket, which also includes a base 1, a frame 2, a first clamping component 3, and a second clamping component 4. The base 1 is fixedly connected to the frame 2. The frame 2 has a plurality of first measuring stations 5 and a plurality of second measuring stations 6 distributed at intervals. The first clamping component 3 is fixed in each first measuring station 5, and the second clamping component 4 is fixed in each second measuring station 6. The frame 2 around each first measuring station 5 and each second measuring station 6 has a plurality of adhesive areas.

[0035] The base 1 is fixedly installed on the turntable of the 3D optical scanner, and multiple marker points and multiple coded points are pasted alternately on the frame 2 around each first measurement station 5 and each second measurement station 6. The 3D optical scanner collects the positions of the multiple marker points and multiple coded points and establishes a reference point frame.

[0036] Subsequently, multiple blades are clamped onto multiple first clamping assemblies 3 and multiple second clamping assemblies 4, respectively. Driving the 3D optical scanner turntable to rotate causes the blades within the base 1 and frame 2 to rotate. The 3D optical scanner can simultaneously acquire photographs of the blades at different angles within one of the measurement stations, as well as the positions of marker points and coded points on the frame 2 surrounding that measurement station. It then automatically stitches the acquired blade photographs to the corresponding positions, completing the measurement of the blade and improving detection accuracy and efficiency.

[0037] Specifically, multiple first measurement stations 5 and multiple second measurement stations 6 are evenly distributed on frame 2. For example... Figure 1 As shown, this embodiment includes 5 first measurement stations 5 and 5 second measurement stations 6, which can sequentially measure ten blades.

[0038] The middle part of the frame 2 is threadedly fixed to the top of the base 1.

[0039] In addition, the frame 2 is made of aluminum alloy, which can improve the service life of the device and also makes it easier to attach marking points and coding points.

[0040] The 3D optical scanner first uses a Plus 45M lens to collect data on multiple marker and coded points pasted on frame 2, and then establishes a reference point frame. (See below.) Figure 6 The diagram shows a reference point frame for either two first measurement stations 5 or two second measurement stations 6.

[0041] After the blade is clamped onto the first clamping assembly 3 and the second clamping assembly 4, the 3D optical scanner turntable is driven to rotate, causing the blade to be measured to rotate. Subsequently, the 3D optical scanner, using an MV270 lens, acquires images of the blade at different angles within one of the measurement stations; simultaneously, using a Plus 45M lens, it acquires the positions of marker points and coded points on the frame 2 surrounding the measurement station. The acquired positions of the marker points and coded points are then matched one-to-one with the positions of the marker points and coded points in the reference frame. The corresponding blade images are automatically stitched together to complete the measurement of one blade, as shown below. Figure 7 As shown, this is the relative position of the measured blade and the reference frame.

[0042] In addition, multiple marker points and multiple coded points need to be manually affixed to the outer surface of frame 2 in an alternating pattern. The marker points are circular, while the coded points are irregularly shaped. The marker points are affixed within a 270mm × 200mm area at any position on the camera lens, consisting of 6-8 points. The coded points are affixed within a 500mm × 330mm area at any position on the camera lens, consisting of 8-10 points.

[0043] Based on the above scheme, the frame 2 includes a first support plate 201, a second support plate 202, a third support plate 203, and a plurality of support columns 204. The base 1 is fixedly connected to the first support plate 201. One end of the plurality of support columns 204 is spaced apart on the first support plate 201. The other end of the support column 204 passes through the second support plate 202 and the third support plate 203 in sequence, and is detachably connected to the second support plate 202 and the third support plate 203 respectively. Each first clamping assembly 3 is located between two adjacent support columns 204 and is detachably connected to the first support plate 201. Each second clamping assembly 4 is located between two adjacent support columns 204 and is detachably connected to the second support plate 202.

[0044] Multiple marker points and multiple coded points can be staggered and pasted on the outer surfaces of the first support plate 201, the second support plate 202, the third support plate 203, and multiple support columns 204 to facilitate the establishment of a reference point framework and improve detection accuracy.

[0045] Specifically, one end of each of the multiple support columns 204 can be evenly distributed on the first support plate 201 at intervals.

[0046] Among them, the outer surfaces of the first support plate 201, the second support plate 202, the third support plate 203 and the multiple support columns 204 can be uniformly pasted with multiple marking points and multiple coding points at staggered intervals, or they can be unevenly pasted with staggered intervals.

[0047] In addition, depending on the actual situation, a fourth support plate may also be included. The other end of the support column 204 extends through the third support plate 203 and is detachably connected to the fourth support plate to increase multiple measurement stations for measuring multiple blades and improve measurement efficiency.

[0048] Specifically, in this embodiment, as follows: Figure 2 As shown, the middle part of the support column 204 is detachably connected to the second support plate 202.

[0049] The first support plate 201 has the same shape in the middle as the top of the base 1, which increases the stability of the frame 2 and the base 1. The second support plate 202 and the third support plate 203 are both rectangular plates.

[0050] Additionally, the first support plate 201, the second support plate 202, and two adjacent support columns 204 form the first measuring station 5. The second support plate 202, the third support plate 203, and two adjacent support columns 204 form the second measuring station 6.

[0051] Based on the above scheme, the support column 204 is a hexagonal prism.

[0052] The support column 204 has multiple surfaces, on which multiple marker points and multiple coding points can be pasted in an alternating pattern to increase the accuracy of the measurement.

[0053] Based on the above scheme, it also includes a first fixing block 205. One end of the support column 204 is fixedly connected to one end of the two first fixing blocks 205 on both sides, and the other end of the first fixing block 205 is fixedly connected to the first support plate 201.

[0054] The two first fixing blocks 205 are located on both sides of one end of the support column 204, which can increase the stability of the support column 204 and prevent the support column 204 from shifting during rotation, thus affecting the measurement quality.

[0055] Based on the above scheme, a second fixing block 206 is also included. The two sides of the middle part of the support column 204 are respectively fixedly connected to one end of the two second fixing blocks 206, and the other end of the second fixing block 206 is fixedly connected to the second support plate 202.

[0056] The two second fixing blocks 206 are located on both sides of the middle of the support column 204, which can increase the stability of the support column 204 and prevent the support column 204 from shifting during rotation, thus affecting the measurement quality.

[0057] Based on the above scheme, both the first fixing block 205 and the second fixing block 206 are right-angled triangular plates.

[0058] Specifically, depending on the actual situation, the first fixing block 205 and the second fixing block 206 can be set to other shapes, such as cubes or cuboids.

[0059] Based on the above scheme, the first clamping assembly 3 includes a first chassis 301, a first support platform 302, a first clamping block 303, a second clamping block 304, a first lead screw 305, and a first handle 306. The first chassis 301 is fixedly connected to the first support plate 201. The first support platform 302 is fixed on the first chassis 301. The first lead screw 305 is installed inside the first support platform 302. One end of the first lead screw 305 is rotatably connected to one end of the first support platform 302. The other end of the first lead screw 305 extends out of the other end of the first support platform 302 and is fixedly connected to the first handle 306. The first clamping block 303 is sleeved on the first lead screw 305 and is threadedly connected to the first lead screw 305. The first clamping block 303 is slidably connected to the first support platform 302. The second clamping block 304 is sleeved on the first lead screw 305 and is fixedly connected to one end of the first support platform 302.

[0060] Place the tenon of the blade in the first clamping block 303 and the second clamping block 304 on the first support platform 302, rotate the first handle 306 to drive the first clamping block 303 to move along the length direction of the first lead screw 305 until the first clamping block 303 and the second clamping block 304 clamp the tenon of the blade, thus completing the clamping of the blade to be tested.

[0061] Based on the above scheme, the second clamping assembly 4 includes a second chassis 401, a second support platform 402, a third clamping block 403, a fourth clamping block 404, a second lead screw 405, and a second handle 406. The second chassis 401 is fixedly connected to the second support plate 202. The second support platform 402 is fixed on the second chassis 401. The second lead screw 405 is installed inside the second support platform 402. One end of the second lead screw 405 is rotatably connected to one end of the second support platform 402. The other end of the second lead screw 405 extends out of the other end of the second support platform 402 and is fixedly connected to the second handle 406. The third clamping block 403 is sleeved on the second lead screw 405 and is threadedly connected to the second lead screw 405. The third clamping block 403 is slidably connected to the second support platform 402. The fourth clamping block 404 is sleeved on the second lead screw 405 and is fixedly connected to one end of the second support platform 402.

[0062] Place the tenon of the blade into the third clamping block 403 and the fourth clamping block 404 on the second support platform 402, and rotate the second handle 406 to move the third clamping block 403 along the length of the second lead screw 405 until the third clamping block 403 and the fourth clamping block 404 clamp the tenon of the blade, thus completing the clamping of the blade to be tested.

[0063] Based on the above scheme, multiple second measuring stations 6 are located above multiple first measuring stations 5, and the multiple second measuring stations 6 are arranged horizontally at intervals, and the multiple first measuring stations 5 are arranged horizontally at intervals.

[0064] Based on the above scheme, the number of multiple second measurement stations 6 and multiple first measurement stations 5 is the same.

[0065] In this implementation case, when in use, the base 1 is fixedly installed on the turntable of the 3D optical scanner, and multiple marker points and multiple coding points are pasted alternately on the outer surface of the frame 2. The 3D optical scanner uses a Plus 45M lens to collect the positions of multiple marker points and multiple coding points and establish a reference point frame.

[0066] Multiple blade tenons to be tested are placed in the first clamping block 303 and the second clamping block 304 on the first support platform 302 in multiple first measurement stations 5. The first handle 306 is rotated to drive the first clamping block 303 to move along the first lead screw 305 until the first clamping block 303 and the second clamping block 304 clamp the tenons of the blade to be tested.

[0067] Multiple blade tenons to be tested are placed in the third clamping block 403 and the fourth clamping block 404 on the second support platform 402 in multiple second measurement stations 6. The second handle 406 is rotated to drive the third clamping block 403 to move along the second lead screw 405 until the third clamping block 403 and the fourth clamping block 404 clamp the tenons of the blades to be tested, thus completing the clamping of all blades to be tested on the frame 2.

[0068] After multiple blades to be tested are clamped in multiple first clamping components 3 or second clamping components 4, the 3D optical scanner turntable is driven to rotate, causing the blades to be tested in the base 1 and frame 2 to rotate. At this time, the 3D optical scanner uses an MV270 lens to acquire photos of the blades to be tested at different angles in one of the measurement stations, and uses a Plus 45M lens to acquire the positions of the marker points and coded points on the frame 2 around the measurement station. The acquired positions of the marker points and coded points are matched one-to-one with the positions of the marker points and coded points in the reference frame, and the corresponding acquired photos of the blades to be tested are automatically stitched together to the corresponding positions to complete the detection of the blades to be tested. After the measurement of the blades in the measurement station is completed, the 3D optical scanner repeats this step to measure the blades to be tested in other measurement stations in turn, until the measurement of all blades in the frame 2 is completed.
