Description

Technical Field

[0001] This utility model belongs to the field of tooling and fixture technology, specifically relating to a rapid pre-alignment fixture for industrial CT inspection equipment. Background Technology

[0002] General-purpose industrial CT inspection equipment can inspect a wide variety of samples, covering materials from low to high density, samples from small to large sizes, and samples from soft biological materials to hard metal castings. Different clamps are required for different samples. Commonly used clamp materials include low-density materials such as foam, modeling clay, carbon fiber, and floral foam, which are simply processed according to the specific sample. These clamps can adapt to various inspection needs, but they are for single use only and may not securely hold the sample. Furthermore, after pre-inspection, it may be found that the sample posture is unsuitable; these disposable clamps cannot finely adjust the sample posture, requiring the clamp to be remade after the sample posture is adjusted.

[0003] Secondly, after the sample is clamped onto the fixture, it is necessary to ensure that the region of interest to be scanned is located on the central axis of the turntable. This ensures that the region of interest remains centered in the detector's field of view during rotational measurement, maximizing the magnification ratio. However, ensuring that the region of interest is located on the central axis of the turntable is usually not achievable with a single clamping. It requires repeatedly opening and closing the industrial CT inspection equipment door for adjustment based on the imaging, resulting in low inspection efficiency. Furthermore, frequent power-on and power-off cycles can adversely affect the lifespan of the industrial CT inspection equipment's X-ray source. Summary of the Invention

[0004] This invention provides a rapid pre-alignment fixture for industrial CT inspection equipment, which solves the problem that existing sample fixtures for industrial CT inspection equipment are disposable and cannot adjust the sample posture.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is a rapid pre-alignment fixture for industrial CT inspection equipment, comprising: A stage assembly includes a bottom platform, a middle platform, and a stage arranged in a stacked manner from bottom to top. The middle platform is slidably connected to the bottom platform via a first horizontal sliding mechanism, and the stage is slidably connected to the middle platform via a second horizontal sliding mechanism. The first horizontal sliding mechanism and the second horizontal sliding mechanism are arranged perpendicularly to each other. A laser alignment device includes a base, a column, and a cross-shaped laser emitter. The base is rotatably coupled to and detachable from the bottom platform, and the rotation axis of the base is coaxial with the central axis of the bottom platform. The bottom end of the column is connected to the base, and the cross-shaped laser emitter is connected to the top end of the column. The center of the cross-shaped laser emitted by the cross-shaped laser emitter is coaxial with the central axis of the bottom platform, and the central axis of the bottom platform is coaxial with the central axis of the turntable of the industrial CT inspection equipment. A clamping assembly, which is mounted on the stage, is used to position the sample to be tested.

[0006] The technical solution of this utility model also includes the following additional technical features: The first horizontal sliding mechanism consists of two sets of parallel linear guide rails, with the guide rail portion fixed to the bottom platform, and the middle platform connected to the slider of the first horizontal sliding mechanism. The second horizontal sliding mechanism consists of two sets of parallel linear guide rails, with the guide rail portion fixed to the middle platform. The platform is connected to the slider of the second horizontal sliding mechanism.

[0007] The base is circular, the bottom platform is disc-shaped, and the base is adapted to be installed around the bottom platform.

[0008] The middle platform and the stage are disc-shaped and are coaxially arranged with the bottom platform.

[0009] The column includes a fixed column and a rotating column. The bottom end of the fixed column is connected to the base, one end of the rotating column is rotatably connected to the top end of the fixed column, and the cross laser emitter is connected to the other end of the rotating column.

[0010] The fixed column includes a fixed section and a telescopic section. The telescopic section is telescopically inserted into the fixed section. The bottom end of the fixed section is connected to the base. One end of the rotating column is rotatably connected to the top end of the telescopic section. The cross laser emitter is connected to the rotating column via a connecting rod. The connecting rod includes a first straight segment and a second straight segment. The first straight segment is telescopically inserted into the rotating column. One end of the second straight segment is vertically connected to the exposed end of the first straight segment. The cross laser emitter is mounted on the other end of the second straight segment.

[0011] The clamp assembly is detachably connected to the stage.

[0012] The clamp assembly includes a support base, a first support plate, and a second support plate; the bottom end of the support base is connected to the stage, and the top end is supported and connected to the first support plate; the bottom end of the first support plate is connected to the stage; the second support plate is slidably connected to the first support plate, forming a sample positioning part with the first support plate, and the second support plate is provided with a locking element for locking the second support plate when it slides into place.

[0013] A slide rail is formed on the platform, and the bottom end of the support base and the bottom end of the first support plate are slidably connected to the slide rail, while the top end of the support base is slidably connected to the first support plate.

[0014] Isolation plates are laid on the opposite surfaces of the first support plate and the second support plate.

[0015] Compared with the prior art, the present invention has the following advantages and positive effects: 1. In use, the cross laser emitted by the cross laser emitter of the laser alignment device is coaxial with the central axis of the bottom platform of the stage assembly. After the position of the cross laser center is determined, the position of the sample positioned by the clamp assembly on the stage can be adjusted by adjusting the position of the stage, so that the region of interest of the sample is quickly aligned with the cross laser center. Since the cross laser center is coaxial with the central axis of the bottom platform of the stage assembly, the alignment of the region of interest of the sample with the central axis of the bottom platform is achieved. Since the central axis of the bottom platform is coaxial with the central axis of the industrial CT inspection equipment turntable, the pre-alignment of the region of interest of the sample with the turntable is achieved. Then, the stage assembly is separated from the laser alignment device, and the aligned stage assembly and sample are installed on the turntable of the industrial CT inspection equipment. Since the central axis of the bottom platform is coaxial with the central axis of the industrial CT inspection equipment turntable, the region of interest of the sample can be aligned with the central axis of the turntable, ensuring that the region of interest to be scanned during the rotation measurement of the sample can be kept in the center of the detector's field of view. There is no need to frequently turn the industrial CT inspection equipment on and off for adjustment, which greatly improves the detection efficiency and effectively avoids the adverse effects of frequent power-on and power-off on the lifespan of the X-ray source of the industrial CT inspection equipment. 2. The rapid pre-alignment fixture of this utility model industrial CT inspection equipment is reusable, which significantly reduces the workload of fixture manufacturing, saves fixture costs, and makes clamping more stable.

Sample to be tested. Detailed Implementation

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Reference Figures 1 to 6 In some embodiments of this utility model, a rapid pre-alignment fixture for industrial CT inspection equipment includes a stage assembly 100, a laser alignment device 200, and a fixture assembly 300.

[0022] The stage assembly 100 includes a bottom platform 110, a middle platform 120 and a stage 130 stacked sequentially from bottom to top. The middle platform 120 and the bottom platform 110 are slidably connected by a first horizontal sliding mechanism, and the stage 130 and the middle platform 120 are slidably connected by a second horizontal sliding mechanism. The first horizontal sliding mechanism and the second horizontal sliding mechanism are arranged perpendicularly.

[0023] The laser alignment device 200 includes a base 210, a column, and a cross laser emitter 220. The base 210 is rotatably coupled to the bottom platform 110 and can be detached from it. The rotation axis of the base 210 is coaxial with the central axis of the bottom platform 110. The bottom end of the column is connected to the base 210, and the cross laser emitter 220 is connected to the top end of the column. The center O of the cross laser emitted by the cross laser emitter 220 is coaxial with the central axis a of the bottom platform 110, that is, the center O of the cross laser emitted by the cross laser emitter 220 is located on the central axis a of the bottom platform 110. The central axis of the bottom platform 110 is coaxial with the central axis of the turntable of the industrial CT inspection equipment.

[0024] The fixture assembly 300 is mounted on the stage 130 and is used to position the sample 1 to be tested.

[0025] Specifically, the first horizontal sliding mechanism can be an X-axis sliding mechanism, and correspondingly, the second horizontal sliding mechanism is a Y-axis sliding mechanism. Then, the middle platform 120 can slide and adjust relative to the bottom platform 110 along the X-axis, and the stage 130 can slide and adjust relative to the middle platform 120 along the Y-axis. Ultimately, the sample 1 to be tested clamped by the clamp assembly 300 on the stage 130 can be positioned relative to the bottom platform 110 in both the X and Y axes.

[0026] The laser alignment device 200 rotates relative to the bottom platform 110 of the stage assembly 100 through the base 210, so that the laser alignment device 200 can rotate around the central axis of the bottom platform 110. This allows the laser emission position to be adjusted circumferentially in the horizontal plane to adjust the alignment of the cross laser center O with various test samples 1 of different contour shapes, thereby meeting the pre-alignment requirements of various test samples 1 of different contour shapes.

[0027] In use, the operator can adjust the position of the stage 130 according to the position indication of the cross laser center O, and then adjust the sample position so that the region of interest of the sample is quickly aligned with the cross laser center. Since the cross laser center is coaxial with the central axis of the bottom platform 110 and the central axis of the bottom platform 110 is coaxial with the central axis of the turntable, the region of interest of the sample 1 to be tested can be accurately adjusted to the central axis of the turntable before being sent into the industrial CT inspection equipment. This achieves pre-alignment of the region of interest of the sample with the turntable of the industrial CT inspection equipment, ensuring that the region of interest to be scanned can remain in the center of the detector's field of view during the rotation measurement of the sample 1 in the industrial CT equipment. This eliminates the need for frequent switching of the industrial CT inspection equipment for adjustment, greatly improving the inspection efficiency and effectively avoiding the adverse effects of frequent switching on and off on the lifespan of the X-ray source of the industrial CT inspection equipment.

[0028] In some embodiments of this utility model, the first horizontal sliding mechanism consists of two sets of parallel X-axis linear guides 140, with their guide rail portions fixed on the bottom platform 110, and the middle platform 120 connected to the slider of the X-axis linear guide 140; the second horizontal sliding mechanism consists of two sets of parallel Y-axis linear guides 150, with their guide rail portions fixed on the middle platform 120, and the stage 130 connected to the slider of the Y-axis linear guide 150. The use of two sets of X-axis linear guides 140 and two sets of Y-axis linear guides 150 ensures smooth and reliable sliding adjustment of the stage 130, which is beneficial for improving adjustment accuracy.

[0029] Of course, each linear guide can be configured with multiple sliders, for example Figure 4 Each linear guide rail shown is equipped with two sliders to further improve the smoothness of the sliding adjustment of the stage 130.

[0030] In some embodiments of this utility model, such as Figure 4 As shown, two guide rail mounting grooves 160 are formed on the top surface of the bottom platform 110 and the top surface of the middle platform 120. The guide rail portion of the X-direction linear guide rail 140 and the guide rail portion of the Y-direction linear guide rail 150 are fixedly installed in the corresponding guide rail mounting grooves 160. Similarly, slider mounting grooves (not shown due to viewing angle) are formed on the bottom surface of the middle platform 120 and the bottom platform 110, and on the bottom surface of the stage 130, to achieve embedded installation of the guide rails and sliders, thereby reducing the distance between the middle platform 120 and the bottom platform 110, and between the stage 130 and the middle platform 120, improving the stability of the entire stage assembly 100, and thus improving the smoothness of the sliding adjustment of the stage 130.

[0031] Since the turntable of industrial CT inspection equipment is usually circular, the bottom platform 110 of the stage assembly 100 is disc-shaped to facilitate coaxial mounting with the turntable. Correspondingly, the base 210 of the laser alignment device 200 is annular, fitted around the bottom platform 110, and can rotate freely around the bottom platform 110, and can also be easily detached from the bottom platform 110. A connecting part 211 extending outward along one of its radial directions is fixed on the base 210, and the column is vertically connected to the connecting part 211, thereby achieving connection with the base 210. When the annular base 210 rotates around the circular bottom platform 110, it drives the column and the cross laser emitter 220 on it to rotate around the circular bottom platform 110, and during the rotation, the center of the cross laser emitted by the cross laser emitter 220 is on the central axis of the bottom platform 110.

[0032] In some embodiments of this utility model, the middle platform 120 and the stage 130 are also correspondingly disc-shaped and coaxially arranged with the bottom platform 110. The stage 130 has a countersunk hole and a threaded hole at its center to facilitate the installation of other clamps.

[0033] In some embodiments of this utility model, the column of the laser alignment device 200 includes a fixed column 230 and a rotating column 240. The bottom end of the fixed column 230 is connected to the base 210, one end of the rotating column 240 is rotatably connected to the top end of the fixed column 230, and the cross laser emitter 220 is connected to the other end of the rotating column 240.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, the rotating connection structure between the rotating column 240 and the fixed column 230 is configured such that the rotating column 240 rotates in a vertical plane around a horizontal axis 233 on the top of the fixed column 230. This horizontal axis 233 is parallel to the radial direction of the stage 130, ensuring that the center of the cross laser emitted by the cross laser emitter 220 remains on the central axis of the bottom platform 110 during the rotation of the rotating column 240. With this structure, the cross laser emitter 220 can not only adjust its laser emission position circumferentially around the central axis of the bottom platform 110 with the base 210, but also adjust its own position by rotating the rotating column 240 when the base 210 is in a fixed position. This further expands the adjustment range of the laser emission position of the cross laser emitter 220 and greatly improves the versatility of the rapid pre-alignment fixture for industrial CT inspection equipment in this embodiment of the invention.

[0035] like Figure 1 As shown, at this time, the rotating column 240 rotates relative to the fixed column 230 to a vertical position, the rotating column 240 and the fixed column 230 are coaxial, and the cross laser emitter 220 emits laser vertically downwards; as Figure 6 As shown, at this time, the rotating column 240 rotates to a horizontal position relative to the fixed column 230, the rotating column 240 is perpendicular to the fixed column 230, and the cross laser emitter 220 emits laser horizontally.

[0036] Furthermore, such as Figure 2 As shown, the fixed column 230 includes a fixed section 231 and a telescopic section 232. The fixed section 231 is tubular, and the telescopic section 232 is telescopically inserted into the fixed section 231. At this time, the fixed column 230 is connected to the base 210 with the bottom end of the fixed section 231. A horizontal rotating shaft 233 is formed on the top end of the telescopic section. The rotating column 240 is rotatably connected to the top end of the telescopic section 232 through the horizontal rotating shaft 233. The cross laser emitter 220 is connected to the rotating column 240 through a connecting rod 250. The rotating column 240 is tubular, and the connecting rod 250 includes a first straight section 251 and a second straight section 252. The first straight section 251 is telescopically inserted into the rotating column 240, and one end of the second straight section 252 is vertically connected to the exposed end of the first straight section 251 (i.e., the end located outside the rotating column 240). That is, the connecting rod 250 is an L-shaped rod, and the cross laser emitter 220 is installed on the other end of the second straight section 252.

[0037] By adjusting the telescopic section 232 and the connecting rod 250, the distance between the cross laser emitter 220 and the sample 1 to be tested can be adjusted in the height or horizontal direction to accommodate samples 1 of different sizes.

[0038] To ensure reliability, after the telescopic section 232 and connecting rod 250 are adjusted to the correct position, they can be tightened and fixed with set screw 340 to keep them firmly in the adjusted position.

[0039] In some embodiments of this utility model, the clamp assembly 300 is detachably connected to the stage 130, that is, the clamp assembly 300 can be detached from the stage 130 to replace and install different clamps in the prior art or self-made clamps, so as to adapt to the clamping and positioning of samples 1 to be tested with different contour shapes, thereby further improving the versatility for different samples.

[0040] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the fixture assembly 300 includes a support base 310, a first support plate 320, and a second support plate 330. The bottom end of the support base 310 is connected to the stage 130, and the top end is connected to the first support plate 320. The bottom end of the first support plate 320 is connected to the stage 130. The second support plate 330 is slidably connected to the first support plate 320, and together with the first support plate 320, they form a sample positioning part. The second support plate 330 is provided with a locking element for locking the second support plate 330 when it slides into place.

[0041] As one implementation method, such as Figure 4 and Figure 5 As shown, the support base 310 and the first support plate 320 are both flat plates. They are arranged opposite each other and are inclined relative to the platform 130. The top of the support base 310 abuts against the upper bottom surface of the first support plate 320, so that the support base 310, the first support plate 320 and the platform 130 form a stable triangular support structure.

[0042] The bottom end of the support base 310 can be screwed to the platform 130 for easy disassembly. Similarly, the bottom end of the first support plate 320 can also be screwed to the platform 130.

[0043] In some embodiments of this utility model, a slide rail 131 is formed on the platform 130, the bottom end of the support base 310 and the bottom end of the first support plate 320 are slidably connected to the slide rail 131, and the top end of the support base 310 is slidably connected to the first support plate 320.

[0044] Specifically, as in Figure 4 and Figure 5 As shown, two slide rails 131 are arranged in parallel, parallel to the X-direction linear guide rail 140. The two ends of each slide rail 131 are fixed to the platform 130, and the part between the two ends protrudes upward from the top surface of the platform 130 to form a sliding guide gap 132 with the top surface of the platform 130. A rotating shaft 311 is rotatably inserted through the bottom of the support base 310. A guide block 312 is rotatably sleeved at each end of the rotating shaft 311. The guide block 312 is embedded in the sliding guide gap 132 and slides in cooperation with the sliding guide gap 132. When the support base 310 is slidably adjusted, the guide block 312 is tightened by the set screw 340.

[0045] Similarly, the bottom end of the first support plate 320 is connected to the slide rail 131 using the same structure as described above, which will not be elaborated here.

[0046] Specifically, for the sliding connection between the top of the support base 310 and the first support plate 320, a first groove 321 with the top end through is formed on the bottom surface of the first support plate 320. A sliding connecting plate 322 is slidably inserted in the first groove 321. The sliding connecting plate 322 can be pulled out from the top of the first groove 321, and the top of the support base 310 is rotatably connected to the sliding connecting plate 322.

[0047] The support base 310 and the stage 130, the first support plate 320 and the stage 130, and the support base 310 and the first support plate 320 are respectively connected by the above-mentioned structure. On the one hand, the support base 310 and the first support plate 320 can be easily disassembled by removing the set screw 340, guide block 312, rotating shaft 311, and sliding connecting plate 322. On the other hand, the support base 310 and the first support plate 320 can be slidably adjusted along the slide rail 131 to adjust the position, thereby adjusting the tilt angle of the first support plate 320, thereby changing the tilt angle of the sample 1 to be tested, so as to be suitable for different sizes of samples 1 to be tested, and to facilitate the pre-centering of the sample 1 to be tested.

[0048] The second support plate 330 is also flat, connected to the lower part of the first support plate 320 and located above the first support plate 320, forming a certain angle with the first support plate 320, such as a 90° angle, and can be used to clamp relatively regular-shaped samples to be tested, such as cuboids.

[0049] By sliding and adjusting the position of the second support plate 330 relative to the first support plate 320, the height of the second support plate 330 can be adjusted, thereby adjusting the lifting height of the sample 1 to be tested to suit samples 1 of different sizes.

[0050] Specifically, such as Figure 5 As shown, the first support plate 320 has a second sliding groove 323 on each of its opposite sides. The bottom surface of the second support plate 330 has an extension 331 at each end. The extension 331 is located on the outside of the second support plate and slides with the two sides of the first support plate 320. After sliding into place, the second support plate 330 is fixed by the top screw 340 (i.e., the locking element is the top screw 340) passing through the extension 331 and pressing against the bottom wall of the second sliding groove 323.

[0051] In some embodiments of this utility model, an isolation plate 350 is laid on the opposite surfaces (i.e., the surfaces in contact with the sample 1 to be tested) of the first support plate 320 and the second support plate 330. The isolation plate 350 is a low-density foam isolation plate 350, which isolates the sample 1 to be tested from the surfaces of the first support plate 320 and the second support plate 330, facilitating the separation of the sample from the fixture after imaging by the industrial CT inspection equipment.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
