Description

Technical Field

[0001] This utility model relates to the field of CT scanning station technology, specifically to an automatic positioning CT scanning station. Background Technology

[0002] Industrial CT scanners use X-rays or gamma rays to penetrate the object being inspected. The attenuated ray signals are received by a detector, and then combined with computer image processing technology to reconstruct two-dimensional tomographic images or three-dimensional images of the object's interior. When scanning an object, an industrial CT scanner needs a scanning table to support the CT scanning table.

[0003] For example, the announcement number CN214427316U (named "An Industrial CT Scanning Workbench") includes an operating table, a worm gear, a rotating table, a moving support unit, a kinetic energy unit, an L-shaped bracket, a lifting unit, a CT scanner mounting bracket, and a CT scanner. The lower end of the worm gear is rotatably mounted on the center of the upper surface of the operating table. The lower end of the rotating table is fixedly mounted on the upper surface of the worm gear. The moving support unit is mounted on the rotating table. The kinetic energy unit is mounted on the upper surface of the operating table. The rear of the L-shaped bracket is open at both ends, and the front lower end of the L-shaped bracket is fixedly mounted on the center of the rear side of the operating table. The lifting unit is mounted on the L-shaped bracket. The moving support unit is used to place the items to be scanned, and it can also move the items left and right to facilitate scanning items of different lengths. The kinetic energy unit drives the worm gear to rotate, thereby rotating the rotating table and the moving support unit to rotate, facilitating 360° scanning of items. The lifting unit drives the CT scanner to move up and down, facilitating scanning of items of different heights.

[0004] The aforementioned CT scanning station uses a rotation and lifting mechanism to assist in omnidirectional scanning and detection of objects. However, the lack of an effective positioning mechanism during the detection process makes it easy for objects to shift and fall during rotational detection. To address this, we provide an automatic positioning CT scanning station. Utility Model Content

[0005] The purpose of this invention is to provide an automatic positioning CT scanning stage to solve the problem mentioned in the background art that the existing CT scanning stage uses a rotation and lifting mechanism to assist in the all-round scanning and detection of objects, but the object lacks an effective positioning mechanism during the detection process, which leads to the problem that the object is prone to displacement and falling during the rotation detection process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic positioning CT scanning stage, including a support base, an integrally formed motor carrier at the upper end of the support base, a servo motor installed inside the motor carrier by screws, a top connector welded to the output shaft of the servo motor, and an extension connecting rod welded to one side of the outer wall of the top connector.

[0007] Also includes:

[0008] A vertical frame is located on one side of the motor carrier. The vertical frame and the support base are an integral structure. The vertical frame has a lifting groove inside, and a threaded screw is installed inside the lifting groove. A screw slider is movably installed on the screw. A support platform is welded to one end of the screw slider through a connecting rod.

[0009] The guide slide is located inside the support platform. There are two guide slides, and each guide slide has a movable seat inside. The upper end of the movable seat is integrally formed with a device holder.

[0010] Preferably, the inner walls on both sides of the guide groove are provided with limiting grooves, and the inner sliders are movably arranged inside the two limiting grooves. The two inner sliders and the movable seat are an integral structure.

[0011] Preferably, one end of the extension link is welded with a device holder, and a CT scanner is fixed in the internal slot of the device holder by screws.

[0012] Preferably, a top support spring is provided at the connection position between the movable seat and one end of the guide slide, and the two ends of the top support spring are welded to one end of the movable seat and one end of the guide slide, respectively.

[0013] Preferably, the two device holders are symmetrically distributed about the center point of the support platform, and the movable seat is guided and movably connected to the support platform through a guide groove.

[0014] Preferably, a lead screw motor is provided at the top of the vertical frame, and the output shaft of the lead screw motor is connected to the threaded lead screw drive through a coupling.

[0015] Preferably, two mounting end slots are provided on each of the two outer walls of the support base, and all four mounting end slots are integral with the support base.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention places the item to be scanned by a CT scanner on a support platform, then separates two positioning plates, allowing the movable seat to move along a guide groove. The restoring force of the top support spring applies a clamping force to the movable seat, acting as the positioning plates, achieving automatic positioning of the placed item. After positioning, the support platform remains stationary to ensure stability. A servo motor drives the top support to rotate slowly, thereby rotating and adjusting the CT scanner to facilitate scanning of the item from different angles. A lead screw motor drives the lead screw slider to move up and down along a lifting groove, allowing the support platform to be raised and lowered. This, combined with the CT scanner, enables omnidirectional scanning. This overcomes the problem of existing CT scanning platforms, which use rotation and lifting mechanisms to assist in omnidirectional scanning but lack an effective positioning mechanism, leading to the item easily shifting and falling during rotational scanning.
