Description

Technical Field

[0001] This application relates to the field of fixtures, and in particular to a fixture for industrial CT scanners. Background Technology

[0002] Industrial CT fixtures are specialized devices designed for industrial computer scanning (CT) systems, primarily used to fix and support items to be inspected.

[0003] After the parts are machined, a CT scanner can be used to inspect the internal quality of the parts, such as detecting internal defects in cast parts, such as porosity, inclusions, and cracks. However, after fixing the object to be inspected with a fixture, it is difficult to adjust the distance between the fixture and the scanner. This makes it difficult to adjust the distance between the object and the scanner. Some objects are too small, and scanning them at too far a distance results in insufficient image clarity. Other objects are too large, and scanning them at too close a distance results in incomplete scanning, affecting the use of the equipment. Moreover, sometimes after scanning one side, it is necessary to scan the other side of the object to improve the scanning accuracy. In this case, the object needs to be removed from the fixture, flipped over, and then fixed again. This method reduces the inspection efficiency. Utility Model Content

[0004] This application provides an industrial CT-specific fixture. When using the fixture, the distance between the fixture and the scanner can be adjusted, which facilitates the inspection of different items and improves the practicality of the fixture. After the fixture fixes the object, it can be flipped to the other side to improve the inspection efficiency.

[0005] To achieve the above objectives, this application adopts the following technical solution: an industrial CT-specific clamp, the clamp comprising:

[0006] base;

[0007] Two boxes are fixedly installed on one side of the base, and threaded rods are provided on both sides of the inner wall of one of the boxes through bearings, and the threaded rods can rotate;

[0008] A sleeve is threadedly fitted onto the outer surface of the threaded rod;

[0009] The upright is fixedly installed on both sides of the inner wall of the other box, and a sliding cylinder is movably sleeved on the outer surface of the upright, which can slide on the outer surface of the upright;

[0010] Two rotating rods are respectively movably mounted on the outer surfaces of the sleeve and the slide, and a frame is fixedly mounted on the opposite side of the two rotating rods. The sleeve is connected to the slide through the two rotating rods and the frame, so that the sleeve moves up and down on the outer surface of the threaded rod when the threaded rod rotates in different directions.

[0011] As a further improvement of this application: hydraulic rods are installed on both sides of the inner wall of the frame, and clamps are fixedly installed on the output ends of the two hydraulic rods. Foam boards are fixedly installed on the opposite side of the two clamps. The object to be tested is placed in the middle of the two foam boards. At this time, the output ends of the two hydraulic rods are controlled to move the two clamps relative to each other, so that the two clamps clamp the two sides of the object to be tested through the two foam boards. The two foam boards are elastic and soft, and protect the two sides of the object when clamping it to prevent deformation caused by long-term compression.

[0012] As a further improvement of this application: a bidirectional motor is installed on one side of one of the housings, and the output shaft of the bidirectional motor is connected to one side of the threaded rod. When the external power switch of the bidirectional motor is turned on, the output shaft of the bidirectional motor can rotate in both directions, and the sleeve can be moved to different positions by controlling the output shaft of the bidirectional motor to rotate in different directions.

[0013] As a further improvement of this application: slots are provided on the opposite sides of the two boxes, and the two slots facilitate the movement of the two rotating rods.

[0014] As a further improvement of this application: a gear is fixedly sleeved on the outer surface of one of the rotating rods, and a rack is meshed on the outer surface of the gear. The teeth on the rack and the teeth on the outer surface of the gear mesh together. Then, the frame is controlled to move up and down, so that the rack drives the gear to rotate in different directions, which in turn drives one of the rotating rods to rotate, so that the frame drives the object to flip over. At this time, pulling the handle makes the rack and gear not mesh together, and the other side of the object can be detected.

[0015] As a further improvement of this application: a hollow cylinder is fixedly embedded on one side of another of the boxes, and a transmission rod is movably embedded in the inner wall of the hollow cylinder, and the transmission rod can slide on the inner wall of the hollow cylinder.

[0016] As a further improvement of this application: a connecting plate is fixedly provided on one side of the transmission rod, and one side of the connecting plate is fixedly provided on one side of the rack. When the transmission rod is moved, the rack is driven to move through the connecting plate.

[0017] As a further improvement of this application: a handle is fixedly provided on one side of the transmission rod, and a scanner is installed on one side of the two boxes. By pulling or pushing the handle, the transmission rod is moved, and the object is scanned and detected by the scanner.

[0018] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0019] 1. In this application, when using the fixture, the object to be inspected is placed between two foam boards. The output ends of two hydraulic rods are controlled to move the two clamping plates relative to each other, clamping the object on both sides through the foam boards. The foam boards are elastic and flexible, protecting the object's sides during clamping and preventing deformation due to long-term compression. The object is then inspected by a scanner. The sliding cylinder can slide on the outer surface of the upright. The sleeve is connected to the sliding cylinder via two rotating rods and a frame. As the threaded rod rotates in different directions, the sleeve moves up and down on the outer surface of the threaded rod. By turning on the external power switch of the bidirectional motor, the output shaft of the bidirectional motor can rotate in both directions. Controlling the bidirectional motor output shaft to rotate in different directions moves the sleeve to different positions, further adjusting the distance between the object and the scanner. Therefore, when using the fixture, the distance between the fixture and the scanner is adjustable, facilitating the inspection of different items and improving the fixture's practicality.

[0020] 2. In this application, when using the fixture, the object is fixed by the clamping plate, and the transmission rod can slide on the inner wall of the hollow cylinder. By pulling or pushing the handle, the transmission rod is moved. When the transmission rod is pushed, the rack is moved through the connecting plate, so that the teeth on the rack and the teeth on the outer surface of the gear mesh together. Then, the frame is controlled to move up and down, so that the rack drives the gear to rotate in different directions, further driving one of the rotating rods to rotate, so that the frame drives the object to flip over. At this time, pulling the handle makes the rack and gear not mesh together, and the other side of the object can be inspected. Thus, after the fixture fixes the object, the other side of the object can be flipped over, improving the inspection efficiency. Attached Figure Description

[0027] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways than those described herein, and therefore this application is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, as Figures 1 to 5 As shown, this application provides a special fixture for industrial CT scanners, which includes:

[0030] Base 1;

[0031] Two boxes 2 are fixedly installed on one side of the base 1, and threaded rods 201 are provided on both sides of the inner wall of one of the boxes 2 through bearings. The threaded rods 201 can rotate.

[0032] Sleeve 202 is threaded onto the outer surface of threaded rod 201;

[0033] The upright 203 is fixedly installed on both sides of the inner wall of another box 2, and the slide cylinder 204 is movably sleeved on the outer surface of the upright 203, and the slide cylinder 204 can slide on the outer surface of the upright 203.

[0034] Two rotating rods 205 are respectively movably mounted on the outer surfaces of the sleeve 202 and the slide 204, and a frame 206 is fixedly mounted on the opposite side of the two rotating rods 205. The sleeve 202 is connected to the slide 204 through the two rotating rods 205 and the frame 206, so that when the threaded rod 201 rotates in different directions, the sleeve 202 moves up and down on the outer surface of the threaded rod 201.

[0035] like Figures 1 to 5As shown, hydraulic rods 207 are installed on both sides of the inner wall of the frame 206. Clamping plates 208 are fixedly installed on the output ends of the two hydraulic rods 207. Foam plates 209 are fixedly installed on the opposite side of the two clamping plates 208. The object to be tested is placed in the middle of the two foam plates 209. At this time, the output ends of the two hydraulic rods 207 are controlled to move the two clamping plates 208 relative to each other, so that the two clamping plates 208 clamp the two sides of the object to be tested through the two foam plates 209. The two foam plates 209 are elastic and soft, and protect the two sides of the object when clamping it to prevent deformation caused by long-term compression.

[0036] like Figures 1 to 5 As shown, a bidirectional motor 210 is installed on one side of one of the housings 2. The output shaft of the bidirectional motor 210 is connected to one side of the threaded rod 201. When the external power switch of the bidirectional motor 210 is turned on, the output shaft of the bidirectional motor 210 can rotate in both directions. By controlling the output shaft of the bidirectional motor 210 to rotate in different directions, the sleeve 202 can be moved to different positions.

[0037] like Figures 1 to 5 As shown, slots 211 are provided on opposite sides of the two boxes 2, which facilitate the movement of the two rotating rods 205.

[0038] like Figures 1 to 5 As shown, a gear 304 is fixedly sleeved on the outer surface of one of the rotating rods 205. A rack 303 is meshed on the outer surface of the gear 304. The teeth on the rack 303 mesh with the teeth on the outer surface of the gear 304. The frame 206 is then controlled to move up and down, causing the rack 303 to drive the gear 304 to rotate in different directions, which in turn drives one of the rotating rods 205 to rotate, causing the frame 206 to flip the object to one side. At this time, pulling the handle 305 will cause the rack 303 and the gear 304 to disengage, allowing the other side of the object to be inspected.

[0039] like Figures 1 to 5 As shown, a hollow cylinder 3 is fixedly embedded on one side of another box 2, and a transmission rod 301 is movably embedded in the inner wall of the hollow cylinder 3. The transmission rod 301 can slide on the inner wall of the hollow cylinder 3.

[0040] like Figures 1 to 5 As shown, a connecting plate 302 is fixedly installed on one side of the transmission rod 301, and one side of the connecting plate 302 is fixedly installed on one side of the rack 303. When the transmission rod 301 is moved, the rack 303 is moved through the connecting plate 302.

[0041] like Figures 1 to 5As shown, a handle 305 is fixedly installed on one side of the transmission rod 301, and a scanner 306 is installed on one side of the two boxes 2. By pulling or pushing the handle 305, the transmission rod 301 is moved, and the object is scanned and detected by the scanner 306.

[0042] Working Principle: When using the clamp, the object to be inspected is placed between two foam plates 209. The output ends of two hydraulic rods 207 are controlled to move two clamping plates 208 relative to each other, clamping the object on both sides through the foam plates 209. The foam plates 209 are elastic and flexible, protecting the object's sides and preventing deformation due to long-term compression. The scanner 306 then inspects the object. The sliding cylinder 204 can slide on the outer surface of the upright 203. The sleeve 202 is connected to the sliding cylinder 204 via two rotating rods 205 and a frame 206. As the threaded rod 201 rotates in different directions, the sleeve 202 moves up and down on the outer surface of the threaded rod 201. By turning on the external power switch of the bidirectional motor 210, the output shaft of the bidirectional motor 210 can rotate in both directions. Controlling the rotation of the bidirectional motor 210's output shaft in different directions moves the sleeve 202 to different positions, further adjusting the position of the object being inspected. The distance between the scanners 306 is adjustable when using the fixture, facilitating the inspection of different items and improving the fixture's practicality. When using the fixture, the object is fixed by the clamping plate 208, and the transmission rod 301 can slide along the inner wall of the hollow cylinder 3. Pulling or pushing the handle 305 moves the transmission rod 301. Pushing the transmission rod 301 moves the rack 303 via the connecting plate 302, causing the teeth on the rack 303 to mesh with the teeth on the outer surface of the gear 304. The frame 206 is then controlled to move up and down, causing the rack 303 to drive the gear 304 to rotate in different directions, further rotating one of the rotating rods 205. This causes the frame 206 to flip the object over. Pulling the handle 305 at this point de-engages the rack 303 and gear 304, allowing inspection of the other side of the object. Thus, after the fixture has fixed the object, it can be flipped over, improving inspection efficiency.

[0043] The above are merely preferred embodiments and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
