Description

Technical Field

[0001] The invention belongs to the technical field of electronic thickness measuring mechanisms, and in particular relates to an X-ray thickness gauge with a dustproof O-shaped scanning frame. Background Art

[0002] X-ray thickness gauge uses the characteristics of X-ray intensity change related to material thickness when X-ray penetrates the material to measure the thickness of the material. It is a non-contact dynamic measuring instrument. It uses PLC and industrial computer as the core, collects calculation data and outputs target deviation value to the rolling mill thickness control system to achieve the required rolling thickness.

[0003] X-ray thickness gauges are mainly used to measure metallurgical materials such as aluminum plates, copper plates, and steel plates. During the production processes of hot rolling, casting rolling, cold rolling, and foil rolling, the X-ray thickness gauge can automatically control these materials to ensure that the thickness of the plate meets the requirements. The X-ray source emits X-rays, which penetrate the material and are then received by the receiving detection head. By measuring the transmission intensity, the thickness of the material can be calculated. The system usually consists of an operating terminal, a cooling system, an X-ray source, a receiving detection head, and a main control cabinet.

[0004] When the workpiece to be measured passes through the X-ray thickness gauge for thickness measurement, if there are still a lot of granular impurities on the surface of the workpiece, it will greatly affect the accuracy of the measurement data. Moreover, the cleaning roller before thickness measurement is usually set for cleaning in a single direction, which cannot effectively remove impurities, thus hindering the improvement of thickness measurement accuracy. In addition, after the workpiece is measured, it is often collected through a box or placed on a shelf by manual operation. This makes manual operation inconvenient and reduces work efficiency. On the other hand, it causes the workpiece to be placed in a disorderly manner, which is not conducive to the subsequent retrieval of the workpiece. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Reference Manual Attached Figure 1 , Figure 2 and Figure 3 As shown, an X-ray thickness gauge with a dustproof O-type scanning frame, including: A workbench 1; a guide cleaning mechanism 2, the guide cleaning mechanism 2 comprises a driving motor 4 fixed on a bottom plate 3, the output shaft of the driving motor 4 extends to a first rotating tooth 5, the outer wall of the first rotating tooth 5 is meshed with a second rotating tooth 7 fixed on a rotating ring 6, the outer wall edge of the rotating ring 6 is provided with a T-shaped rolling groove placed on a circular ring 8, and the bottom end of the circular ring 8 is fixed to the bottom plate 3 through a bracket, the rotating ring 6 is connected to an X-ray emitter 9 adapted thereto, and a detector 10 placed on the workbench 1 is provided directly below the X-ray emitter 9; Among them, both ends of the outer wall of the output shaft of the driving motor 4 are connected to the rotating wheels 12 symmetrically with the center of the workbench 1 through the first conveyor belt 11, and the first conveyor belts 11 are kept parallel to each other. One end of the rotating wheel 12 passes through the cover body and extends to the reciprocating screw 13. The reciprocating screw 13 is spirally driven with a screw nut fixed on the first slider 14. The top ends of the first sliders 14 are connected by a cross beam 15, and a brush plate 16 is installed at the bottom of the cross beam 15 by adhesive fixation.

[0022] A thickness measuring mechanism is provided. After the driving motor 4 is started, the rotating ring 6 on the second rotating tooth 7 can be driven to rotate through the first rotating tooth 5, and then the X-ray emitter 9 can be rotated at a certain angle and cooperate with the detector 10, so as to obtain comprehensive thickness measurement data of the workpiece at multiple angles. At the same time, when the rotating ring 6 rotates on the circular ring 8, a T-shaped rolling groove is provided, which can effectively prevent the rotating ring 6 from deviating from its position during rotation, thereby improving the working stability of the device.

[0023] Specifically, the X-ray emitter 9 cooperates with the detector 10 to detect the corresponding thickness of different workpieces. In addition, after the drive motor 4 is started, it can drive the rotation of the first rotating tooth 5, and under the action of the gear meshing transmission, drive the rotating ring 6 on the second rotating tooth 7 to rotate. When the rotating ring 6 rotates on the circular ring 8, the T-shaped rolling groove not only gives the rotating ring 6 corresponding support force, but also prevents the rotating ring 6 from deviating from its position during the rotation process, thereby ensuring the stability of the rotating ring 6 during rotation.

[0024] In addition, during the rotation of the rotating ring 6, the X-ray emitter 9 can be driven to rotate at a certain angle, so that through rotation at multiple angles, multiple detection thickness data of the workpiece can be obtained. After the drive motor 4 is started, the reciprocating screw 13 on the rotating wheel 12 can be driven to rotate through the first conveyor belt 11. Since the first conveyor belt 11 is arranged in parallel, the reciprocating screws 13 at both ends can be driven to rotate in the same direction at the same time, and the transmission parts can prevent structural interference during the movement, thereby ensuring the normal movement of the transmission parts.

[0025] When the reciprocating screw 13 rotates, under the action of the spiral transmission, the brush plate 16 connected to the cross beam 15 on the first slider 14 can move back and forth horizontally, and then perform back and forth friction cleaning on the workpiece, which can effectively remove impurities and prevent particulate impurities from adhering to the surface of the workpiece, resulting in technical problems such as poor accuracy of detection data. Moreover, the brush plate 16 is installed on the brush plate 16 by adhesive fixation, which can effectively facilitate the installation and disassembly of the brush plate 16, is beneficial to personnel operation and improves work efficiency.

[0026] refer to Figure 1 , Figure 8 and Fig. 9 , the workpiece collecting mechanism 17, the workpiece collecting mechanism 17 includes a box body 18 placed on the bottom plate 3, the box body 18 and the workbench 1 are connected by an inclined plate 19, and the workpiece collecting mechanism 17 is used to arrange the workpieces in layers after the thickness measurement work is completed.

[0027] The workpiece collecting mechanism 17 also includes a first bevel gear 20 placed on the rotating wheel 12, and the outer wall of the first bevel gear 20 is meshed with a second bevel gear 22 fixed on the driving wheel 21. One end of the driving wheel 21 passes through the cover and is connected to a driven wheel 24 placed on the box body 18 through a second conveyor belt 23. One end of the driven wheel 24 is connected to a first sprocket 25 placed on the side wall of the box body 18. The first sprocket 25 and the second sprocket 26 are connected by a chain 27. An annular track connected to the chain 27 is provided on the side wall of the box body 18. The first sprocket 25 and the second sprocket 26 are symmetrically distributed relative to the center of the box body 18 and have the same diameter. The chains 27 are fixedly connected by a center rod 28, and an L-shaped support plate 29 with an opening facing the side of the inclined plate 19 is detachably fixedly installed on the center rod 28.

[0028] A workpiece collecting mechanism 17 is provided. After the driving motor 4 is started, the rotating wheel 12 can drive the first bevel gear 20 to rotate, and transmit the power to the driving wheel 21 on the second bevel gear 22, which can play an effective role in power reversing and regulation. Under the transmission of the second conveyor belt 23, the power is transmitted to the driven wheel 24. At this time, the first sprocket 25 on the driven wheel 24 rotates, and cooperates with the second sprocket 26, and the chain 27 moves in a circular track, which can drive the center rod 28 and the L-shaped support plate 29 on the chain 27 to move synchronously. Since the opening of the L-shaped support plate 29 is located on one side of the inclined plate 19, the workpiece that has fallen can be effectively supported and connected, and multiple workpieces can be effectively placed in layers, thereby ensuring the orderliness of the workpiece placement.

[0029] Compared with the technical solution of directly setting an L-shaped support plate 29 on the conveyor belt, the L-shaped support plate 29 will be driven to flip during the rotation of the conveyor belt, thereby pouring out the collected workpieces, which is not conducive to the safety of the device. The technical solution of the present invention sets the L-shaped support plate 29 at the center of the chain 27. Relative to the rotation of the chain 27, the L-shaped support plate 29 itself will not tilt and rotate, but will only move in the circular track, thereby allowing the workpieces to be placed in layers.

[0030] After the thickness detection of the workpiece is completed, under the action of the pushing cylinder 37, the workpiece can slide into the box 18 through the inclined plate 19 for collection. After the driving motor 4 is started, it can drive the rotation of the first bevel gear 20. Under the reversing transmission of the bevel gear, the second conveyor belt 23 can drive the rotation of the driven wheel 24. Then, under the transmission action of the chain 27, the first sprocket 25 and the second sprocket 26 can rotate, and the chain 27 can be driven to rotate in a circular track, so that the L-shaped support plate 29 on the center rod 28 can rotate synchronously, and the position of the L-shaped support plate 29 relative to the center rod 28 remains "relatively stationary", and its own shape and position will not undergo relative displacement changes during the rotation process. In this way, the workpieces that slide into the box 18 can be placed in layers, which is beneficial to the flatness of the workpiece placement.

[0031] Specifically, a movable opening connected to the driven wheel 24 is opened on the box body 18, and the driving wheel 21 and one end of the driven wheel 24 are integrally formed and connected with a retaining ring 30. When the driving motor 4 drives the cleaning mechanism to clean the surface of the workpiece back and forth, it can synchronously drive the rotation of the driven wheel 24. Under the action of mechanical transmission, the workpieces can be collected in an orderly manner, and the opening of the L-shaped support plate 29 is arranged toward the side of the inclined plate 19, so that it can directly support and connect the sliding workpiece, and the protruding part at one end can protect and shield the workpiece to prevent deviation during the sliding process. By extension, an elastic pad can be provided on the side wall of the L-shaped support plate 29, so that it can provide a better protective buffering effect on the workpiece, thereby improving the safety of the device.

[0032] refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 One end of the first slider 14 is fixedly connected to the first gear plate 32 through the push rod 31, and the outer wall of the first gear plate 32 is meshed with the second gear plate 34 through the third rotating tooth 33. The first gear plate 32 and the second gear plate 34 are vertically staggered up and down, and both ends of the movable shaft on the third rotating tooth 33 are connected to the side wall of the cover body through bearings, and a strip groove connected to the first gear plate 32 is opened on the cover body.

[0033] A second slider 35 is fixedly installed on the top of the second gear plate 34. The second slider 35 is connected with a slide groove along the length direction of the cover body, and the top of the second slider 35 is movably connected with a guide wheel 36 through a fixed rod. As the drive motor 4 is started, the second slider 35 drives the guide wheels 36 at both ends to move toward the center or separate.

[0034] Specifically, during the horizontal movement of the first slider 14, the push rod 31 can drive the movement of the first gear plate 32. Under the gear meshing transmission, the third rotating tooth 33 in the cover body can be rotated, and at the same time, the second gear plate 34 on the third rotating tooth 33 can be centered horizontally. Moreover, the first gear plate 32 and the second gear plate 34 are vertically staggered and arranged up and down, so that when the second gear plate 34 performs the reversing movement, it can also avoid the interference between the first gear plate 32 and the second gear plate 34 in movement. At the same time, the strip groove and the slide groove on the cover body respectively provide corresponding activity space for the movement of the first gear plate 32 and the second gear plate 34. During the back-and-forth centering movement, the second slider 35 can play a conveying and guiding effect on the horizontally moving workpiece, thereby preventing the workpiece from deviating from its position or even slipping during the horizontal movement on the workbench 1.

[0035] A guide cleaning mechanism 2 is set. After the driving motor 4 is started, it can drive the rotating wheels 12 at both ends to rotate through the first conveyor belt 11, and drive the reciprocating screw 13 to rotate. Under the action of the spiral transmission, the first slider 14 can move back and forth in the horizontal direction, so that the pushed workpiece can be cleaned back and forth under the action of the brush plate 16, so that the granular impurities on the surface of the workpiece can be effectively removed, thereby ensuring the cleanliness of the workpiece surface and improving the accuracy of the thickness measurement data. In addition, when the first slider 14 moves, the third rotating teeth 33 can be driven to rotate through the first gear plate 32, and the staggered second gear plates 34 can be driven to move closer or separate in the centering. During the movement of the second gear plate 34, the guide wheel 36 on the fixed rod can be driven to move synchronously, which can effectively limit the centering of the pushed workpiece, prevent the workpiece from deviating from its position or even leaving the moving track during the transportation process, ensure the stable progress of the thickness measurement work, and adapt to the centering and guiding work of workpieces of different sizes, greatly improving the applicability of the device.

[0036] The X-ray thickness gauge with a dustproof O-shaped scanning frame also includes a pushing cylinder 37 placed on the workbench 1, one end of the piston rod on the pushing cylinder 37 is connected to a baffle 38 placed between the guide wheels 36, a detection area placed on the workbench 1 is formed between the X-ray emitter 9 and the detector 10, pillars placed on the ground are installed around the bottom of the workbench 1, and positioning holes are opened at the connection between the workbench 1 and the cover body and are connected by locking and fixing with positioning pins, and a rectangular groove placed on the bottom plate 3 is provided at the bottom of the box body 18.

[0037] The support column at the bottom of the workbench 1 can be set in a ring shape, and a ring pad made of elastic material can be added, which can increase the elastic buffering function of the device while expanding the contact surface, thereby further improving the safety of the device.

[0038] Specifically, the guide wheels 36 on the fixed rod are equidistantly distributed, which can expand the contact surface with the workpiece, and the guide wheel 36 itself is rotatably connected to the fixed rod, and can be rotated by friction during the movement of the workpiece, thereby playing a role of rotational guidance. At the same time, the cover body can not only be installed on the workbench 1 by locking and fixing with locating pins, but can also be fixed by bolt assemblies and the like. The above-mentioned bolt connection method is a conventional technical means for technical personnel in this field, so the present invention does not have corresponding drawings, but it does not affect the effective implementation of the technical solution of the present invention.

[0039] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.
