A digital X-ray inspection workpiece fixing device

Abstract

This utility model relates to the field of digital X-ray inspection technology and discloses a digital X-ray inspection workpiece fixing device, including a fixing base, on one side of which the workpiece to be inspected is mounted. A fixing component is disposed inside the fixing base, and a locking component is mounted on the top of the fixing base. This digital X-ray inspection instrument fixing device achieves initial engagement and positioning through connecting blocks on both sides of the workpiece and connecting grooves on the inner wall of the fixing base. A rotating knob drives the threaded rod to rotate, causing the drive plate to move stably downwards along the sliding rod, allowing the interlocking blocks to precisely embed into the interlocking grooves on the top of the connecting blocks. This forms a double mechanical fixing structure of interlocking and locking, replacing the traditional fixing method that relies solely on friction. The rigid connection avoids the attenuation of clamping force caused by long-term use or vibration impact, effectively preventing the workpiece from shifting or shaking during rotational inspection, and significantly improving the reliability and durability of the fixing effect.

Description

Technical Field

[0001] This utility model relates to the field of digital X-ray inspection technology, specifically to a digital X-ray inspection workpiece fixing device. Background Technology

[0002] A digital X-ray inspection instrument is an advanced device used for non-destructive testing. It receives X-ray or gamma-ray signals that penetrate an object and directly converts them into digital images, enabling the visual inspection of the object's internal structure, defects, or composition.

[0003] Existing technology publication CN220508824U patent document provides a digital X-ray inspection workpiece fixing device. This fixing device has a cavity inside the fixing base to facilitate the fixed installation of a flat panel detector and protect the flat panel detector. The setting of the connecting strip facilitates the fixed connection of two fixing bases, thereby firmly fixing and protecting the flat panel detector. The setting of the connecting groove facilitates the fitting of the connecting strip to the outside of the connecting strip, thereby fixing the two fixing bases. The setting of the fixing knob facilitates the fixing of the connecting strip inserted in the connecting groove, thereby fixing the two fixing bases.

[0004] While the aforementioned prior art can securely protect the flat panel detector and allow it to move around the pipe for inspection, the existing technology relies on the friction of a knob to clamp the detector between two mounting bases. However, this friction-dependent installation method is prone to loosening due to vibration, impact, or slight displacement during long-term use or adjustment, leading to a decrease in clamping force and reduced detector fixation. Therefore, we need a digital X-ray inspection workpiece fixing device. Utility Model Content

[0005] The purpose of this utility model is to provide a digital X-ray inspection workpiece fixing device to solve the problem in the above-mentioned background technology where the fixing device uses the friction of a fixing knob to clamp the workpiece between two mounting seats. However, this installation method that relies solely on friction is prone to loosening of the knob due to vibration, impact or slight displacement during long-term use or rotation adjustment of the equipment, resulting in a decrease in clamping force and a reduction in the fixing effect of the workpiece.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A digital X-ray inspection workpiece fixing device includes a fixing base, on one side of which the workpiece to be inspected is mounted, a fixing component is disposed inside the fixing base, and a locking component is mounted on the top of the fixing base. The fixing component includes a connecting groove, a connecting block is engaged with the inner wall of the connecting groove, a fitting groove is opened on the top of the connecting block, and a fitting block is engaged with the inner wall of the fitting groove. A driving plate is fixedly connected to the top of the fitting block, and a threaded rod is threadedly connected to the inner wall of the driving plate. A knob is fixedly connected to one end of the threaded rod, and a slide rod is slidably connected to the inner wall of the driving plate. The locking assembly includes a fixing plate, a rotating wheel is mounted on one side of the fixing plate, and a lead screw is provided on one side of the rotating wheel. A mating plate is threaded to the outer surface of the lead screw, and a limit rod is slidably connected to the inner wall of the mating plate. A tapered groove is opened on the outer surface of the knob, and a tapered block is fixedly connected to one side of the mating plate.

[0007] Preferably, a wheel seat is installed on one side of the fixed base, and a strap roller is provided on the top of the fixed base.

[0008] Preferably, one side of the connecting block is fixedly connected to one side of the workpiece being inspected, and there are two connecting blocks. The connecting blocks are symmetrically arranged about the vertical axis of the workpiece being inspected, and the shape and size of one side of the connecting block match the shape and size of the inner wall of the connecting groove.

[0009] Preferably, the bottom of the interlocking block extends into the inner wall of the interlocking groove and connects with the connecting block, and the shape and size of the interlocking groove match the shape and size of the interlocking block.

[0010] Preferably, the external thread of the threaded rod matches the internal thread of the drive plate, and one end of the threaded rod passes through the drive plate. There are two slide rods, and the slide rods are symmetrically arranged about the perpendicular bisector of the threaded rod.

[0011] Preferably, there are two docking plates, which are symmetrically arranged about the vertical axis of the knob. The threads on both sides of the lead screw have opposite directions, and the lead screw and the limiting rod are symmetrically arranged about the vertical axis of the docking plates.

[0012] Preferably, one end of the conical block extends into the inner wall of the conical groove and connects to the knob, and the shape and size of one end of the conical block match the shape and size of the inner wall of the conical groove. Both the conical block and the conical groove are conical in shape and size.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this digital X-ray inspection workpiece fixing device, 1. This utility model uses the connecting blocks on both sides of the workpiece to form a preliminary engagement and positioning with the connecting grooves on the inner wall of the fixed seat. With the rotation of the knob, the threaded rod is driven to rotate, which drives the drive plate to move steadily down along the slide rod, so that the fitting block is accurately embedded into the fitting groove at the top of the connecting block, forming a double mechanical fixing structure of engagement and locking. This replaces the traditional fixing method that relies solely on friction. The rigid connection avoids the attenuation of clamping force caused by long-term use or vibration and impact, effectively preventing the workpiece from shifting or shaking during the rotation test, and significantly improving the reliability and durability of the fixing effect.

[0014] 2. This utility model uses a rotating wheel to drive a lead screw to rotate. The reverse threads on both sides of the lead screw drive two mating plates to move relative to each other along a limiting rod. This allows the conical block on one side of the mating plate to precisely embed into the conical groove on the outer surface of the knob, forming a mechanical lock on the knob. This structure restricts the accidental rotation of the knob and avoids a decrease in the clamping force of the fixing components due to the knob loosening. It ensures that the inspected workpiece maintains a stable position during long-term testing or under complex working conditions. This not only eliminates the safety hazard of equipment falling off, but also ensures the stability and accuracy of image acquisition during X-ray inspection. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A digital X-ray inspection workpiece fixing device includes a fixing base 1, a workpiece 2 to be inspected is installed on one side of the fixing base 1, a fixing component 3 is provided inside the fixing base 1, and a locking component 4 is installed on the top of the fixing base 1. The fixing component 3 includes a connecting groove 301, a connecting block 302 is engaged with the inner wall of the connecting groove 301, a fitting groove 303 is provided on the top of the connecting block 302, and a fitting block 304 is engaged with the inner wall of the fitting groove 303. A driving plate 305 is fixedly connected to the top of the fitting block 304, and a threaded rod 306 is threadedly connected to the inner wall of the driving plate 305. A knob 307 is fixedly connected to one end of the threaded rod 306, and a slide rod 308 is slidably connected to the inner wall of the driving plate 305. The locking assembly 4 includes a fixing plate 401, a rotating wheel 402 is mounted on one side of the fixing plate 401, and a lead screw 403 is provided on one side of the rotating wheel 402. A mating plate 404 is threadedly connected to the outer surface of the lead screw 403, and a limit rod 405 is slidably connected to the inner wall of the mating plate 404. A tapered groove 406 is opened on the outer surface of the knob 307, and a tapered block 407 is fixedly connected to one side of the mating plate 404.

[0019] Through the above technical solution, the connecting blocks 302 on both sides of the workpiece 2 are initially engaged and positioned with the connecting grooves 301 on the inner wall of the fixed seat 1. With the rotation of the knob 307, the threaded rod 306 is driven to rotate, which drives the drive plate 305 to move steadily down along the slide bar 308. This allows the fitting block 304 to be precisely embedded in the fitting groove 303 at the top of the connecting block 302, forming a double mechanical fixing structure of engagement and locking. This replaces the traditional fixing method that relies solely on friction. The rigid connection avoids the attenuation of clamping force caused by long-term use or vibration and impact, effectively preventing the workpiece 2 from shifting or shaking during the rotation detection process, and significantly improving the reliability and durability of the fixing effect.

[0020] Specifically, a wheel seat 5 is installed on one side of the fixed seat 1, and a strap roller 6 is provided on the top of the fixed seat 1.

[0021] Through the above technical solution, the wheel seat 5 enables the entire detector to maintain rotation during the rotation of the pipeline, reducing friction, while the binding roller 6 is equipped with an elastic binding belt, which causes the detector to rotate around the pipeline under the action of the binding belt.

[0022] Specifically, one side of the connecting block 302 is fixedly connected to one side of the workpiece 2 being inspected, and there are two connecting blocks 302. The connecting blocks 302 are symmetrically arranged about the vertical line of the workpiece 2 being inspected, and the shape and size of one side of the connecting block 302 match the shape and size of the inner wall of the connecting groove 301.

[0023] Through the above technical solution, the symmetrically arranged connecting blocks 302 and connecting grooves 301 form a precise engagement, providing double-sided positioning support for the inspected workpiece 2, avoiding skewing during installation. The shape matching of the connecting blocks 302 and connecting grooves 301 ensures that the two fit tightly together, forming a preliminary mechanical fixation, laying a stable foundation for the subsequent locking structure.

[0024] Specifically, the bottom of the mating block 304 extends into the inner wall of the mating groove 303 and connects with the connecting block 302, and the shape and size of the mating groove 303 match the shape and size of the mating block 304.

[0025] Through the above technical solution, the engagement of the interlocking block 304 and the interlocking groove 303 forms a secondary lock. Based on the initial engagement of the connecting block 302 and the connecting groove 301, the vertical displacement of the connecting block 302 is further restricted, preventing the inspected workpiece 2 from loosening and detaching due to vibration or external force. The rigid engagement replaces frictional fixation, thereby improving the reliability of the fixation.

[0026] Specifically, the external thread of the threaded rod 306 matches the internal thread of the drive plate 305, and one end of the threaded rod 306 passes through the drive plate 305. There are two slide rods 308, and the slide rods 308 are symmetrically arranged about the perpendicular bisector of the threaded rod 306.

[0027] Through the above technical solution, the threaded engagement between the threaded rod 306 and the drive plate 305 converts the rotational motion of the knob 307 into the linear motion of the drive plate 305, thereby achieving precise lifting and lowering of the mating block 304. The symmetrically arranged slide rods 308 provide guidance for the drive plate 305, preventing rotational deviation during lifting and lowering, ensuring that the mating block 304 can be accurately embedded in the mating groove 303, improving operational stability, and achieving the effect of controlling the lifting and lowering of the mating block 304.

[0028] Specifically, there are two docking plates 404, and the docking plates 404 are symmetrically arranged with the vertical line of the knob 307 as the axis of symmetry. The threads on both sides of the lead screw 403 are opposite in direction, and the lead screw 403 and the limiting rod 405 are symmetrically arranged with the vertical line of the docking plate 404 as the axis of symmetry.

[0029] Through the above technical solution, the reverse thread design on both sides of the lead screw 403 enables the two mating plates 404 to move synchronously in opposite directions along the limiting rod 405 when the wheel 402 rotates. The limiting rod 405 ensures that the moving trajectory of the mating plate 404 is stable and avoids deviation, providing structural guarantee for the precise fitting of the conical block 407 and the conical groove 406.

[0030] Specifically, one end of the conical block 407 extends into the inner wall of the conical groove 406 and connects to the knob 307, and the shape and size of one end of the conical block 407 match the shape and size of the inner wall of the conical groove 406. Both the conical block 407 and the conical groove 406 are conical in shape and size.

[0031] Through the above technical solution, after the conical block 407 and the conical groove 406 are tightly fitted together, the rotation of the knob 307 can be restricted, forming a mechanical lock. The matching shape of the two ensures tight contact, effectively preventing the knob 307 from rotating unexpectedly due to vibration or external force, and eliminating the risk of loosening of the fixing component 3 from the source.

[0032] Working Principle: When using the fixing device of this digital X-ray inspection instrument, the device is first equipped with an external power supply to power the equipment inside. First, align the connecting blocks 302 on both sides of the workpiece 2 under inspection with the connecting grooves 301 on the inner wall of the fixing base 1. Push the workpiece 2 under inspection so that the connecting blocks 302 are inserted into the connecting grooves 301 until they are fully engaged, thus forming a preliminary mechanical positioning between the connecting blocks 302 and the connecting grooves 301. Then, rotate the knob 307, which drives the threaded rod 306 to rotate synchronously. This rotational motion is converted into a linear downward movement of the drive plate 305 along the slide rod 308. The fitting block 304 at the bottom of the drive plate 305 moves downward accordingly, precisely fitting into the fitting groove 301 at the top of the connecting block 302. Within 3, a double fixing structure of locking and clamping is formed. Then, the rotating wheel 402 on one side of the fixing plate 401 is rotated, which drives the lead screw 403 to rotate. Since the threads on both sides of the lead screw 403 rotate in opposite directions, the two mating plates 404 move closer to each other along the limiting rod 405. The conical block 407 on one side of the mating plate 404 moves inward accordingly and gradually embeds into the conical groove 406 on the outer surface of the knob 307. After the conical block 407 and the conical groove 406 are tightly fitted, the rotational freedom of the knob 307 is restricted by the self-locking principle, forming a mechanical lock. This completely prevents the knob 307 from being accidentally loosened due to vibration or external force. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
