Description

Technical Field

[0001] The utility model belongs to the technical field of nondestructive testing equipment, and specifically relates to a high-precision ray nondestructive testing platform. Background Art

[0002] X-ray nondestructive testing equipment, as one of the five conventional nondestructive testing technologies, is widely used. It uses the principle that X-rays can penetrate objects that visible light cannot penetrate, and in the process of penetration, they undergo complex physical and chemical reactions with the material, such as ionization, fluorescence excitation, photochemical reactions, etc. If there are defects in a local area of ​​the workpiece, it will change the attenuation of the object to the rays, causing changes in the intensity of the transmitted rays. By using certain detection methods, such as film photosensitization, to detect the intensity of the transmitted rays, it is possible to determine whether there are defects in the workpiece and the location and size of the defects.

[0003] Existing nondestructive testing equipment mainly includes a platform and a rocker arm, wherein an imager and an X-ray source are installed at both ends of the rocker arm respectively. The rocker arm rotates in a vertical plane, and the platform is a fixed table top, and the imager and the X-ray source are also fixed. However, due to the complex structure of many parts and components, if nondestructive testing cannot be performed on the parts and components in all directions, the inspection of the parts and components will be incomplete and easy to miss. Since the existing nondestructive equipment can only perform inspections by vertical irradiation, it is very likely that the inspection will be incomplete. Utility Model Content

[0033] The platform 2 is installed in the middle of the housing 1 for placing components, and the imaging component 4 and the ray component 3 are located on the upper and lower sides of the platform 2 for generating light sources and receiving light sources for imaging;

[0034] Furthermore, a control computer 11 for controlling the device is installed on the outside of the shell 1 through a bracket, and a track door 12 is provided on the front of the shell 1, which can be opened when placing objects and closed during detection to prevent damage to the human body caused by radiation.

[0035] See attached Figure 3-4 The platform 2 includes a supporting portion 21, a moving portion 22 and a placing portion 23, the moving portion 22 is slidably mounted on the top surface of the supporting portion 21, and the placing portion 23 is slidably mounted on the top surface of the moving portion 22;

[0036] The support portion 21 includes a fixed platform 211 fixedly installed inside the housing 1, and first rails 214 are fixedly installed on both sides of the fixed platform 211;

[0037] The moving part 22 includes a central platform 221, and first sliding sleeves 225 are fixedly installed on both sides of the bottom surface of the central platform 221 in the horizontal direction. The first sliding sleeves 225 are slidably installed on the first track 214, and a second track 226 is fixedly installed on the longitudinal flow side of the top surface of the central platform 221;

[0038] The placement portion 23 includes a placement platform 231 , and second sliding sleeves 233 are fixedly installed on both sides of the bottom surface of the placement platform 231 in the longitudinal direction. The second sliding sleeves 233 are slidably installed on the second rail 226 ;

[0039] In order to drive the placement platform 231 to move horizontally, a first stepper motor 212 is fixedly installed on the horizontal side of the fixed platform 211, and its power output end is fixedly connected to the first screw rod 213 through a coupling. At the same time, a first nut seat 222 is fixedly installed on the horizontal side of the central platform 221. By threading the first nut seat 222 onto the first screw rod 213, the first stepper motor 212 can be used to drive the first screw rod 213 to rotate, so that the first nut seat 222 moves on its surface, thereby driving the central platform 221 to slide horizontally along the first track 214, and synchronously driving the placement platform 231 to move horizontally;

The power output end of the reducer 246 extends to the inside of the track plate 241 and is fixedly connected to the gear 245. When adjusting the position of the component, the servo motor 243 drives the gear 245 to rotate through the reducer 246, so that the racks 244 are synchronously slid toward each other, thereby driving the two groups of clamping jaws 242 to move synchronously, clamping the component, making it more stable when moving, avoiding shaking or tipping, so as not to affect the detection;

[0043] Furthermore, a rubber strip is fixed inside the clamping jaw 242 to prevent damage to components when the clamping jaw 242 is clamping;

[0044] Of course, a clamping portion 24 may also be provided in this embodiment.

[0045] See attached Figure 3 and Figure 6 The ray assembly 3 includes an X-ray source 36 and a vertical support 31 vertically installed inside the shell 1, a first linear motor 32 is fixedly installed on the vertical support 31, a first mounting seat 33 is fixedly installed on the power output end of the first linear motor 32, a first hollow rotating platform 34 is fixedly installed on the first mounting seat 33, a first mounting plate 35 is fixedly installed on the power output end of the first hollow rotating platform 34, the X-ray source 36 is fixedly installed on the first mounting plate 35, the vertical distance between the X-ray source 36 and the parts can be adjusted by the first linear motor 32, so that the X-rays can fully cover the parts, and the X-ray source 36 can be rotated and adjusted at a fixed angle by the first hollow rotating platform 34, thereby changing the deflection angle of the X-ray source 36 relative to the parts, so that it irradiates different sides of the parts, and the parts are detected more comprehensively.

[0046] See attached Figure 3 and Figure 7The imaging assembly 4 includes an imager 46 and a horizontal support arm 41 horizontally installed inside the shell 1, a second linear motor 42 is fixedly installed on the horizontal support arm 41, a second mounting seat 43 is fixedly installed on the power output end of the second linear motor 42, a second hollow rotating platform 44 is fixedly installed on the second mounting seat 43, a second mounting plate 45 is fixedly installed on the power output end of the second hollow rotating platform 44, the imager 46 is fixedly installed on the bottom surface of the second mounting plate 45, the vertical distance between the imager 46 and the component can be adjusted by the second linear motor 42, and then cooperate with the X-ray source 36, so that the light source can be completely imaged thereon, and at the same time, the second hollow rotating platform 44 can change the deflection angle of the imager 46 relative to the component synchronously when the X-ray source 36 changes the deflection angle relative to the component, so that the light source can be completely imaged thereon.

[0047] According to the above structure, by using the radiation component 3 and the imaging component 4, not only can the detection be performed in the vertical direction, but also the detection can be performed from different sides of the parts, so that the detection is more comprehensive, the probability of missed detection is reduced, and the detection accuracy is higher.

[0048] The working principle of the utility model is as follows: when in use, first, open the track door 12, place the parts on the center of the top surface of the placement platform 231, then close the track door 12, and control the device through the control computer 11;

[0049] Secondly, the distance between the X-ray source 36 and the imager 46 and the parts is vertically adjusted by the first linear motor 32 and the second linear motor 42, so that the X-rays can fully cover the parts and be imaged on the imager 46. At the same time, the first stepper motor 212 and the second stepper motor 223 are synchronously started, and the lateral and longitudinal positions of the placement platform 231 in the plane can be adjusted by driving the first screw rod 213 to rotate relative to the first nut seat 222 and driving the second screw rod 224 to rotate relative to the second nut seat 232, so that the parts can be located at the center of the light source, making the detection more comprehensive;

[0050] Finally, by the first hollow rotating platform 34 and the second hollow rotating platform 44 rotating towards each other, the deflection angle of the X-ray source 36 relative to the component can be changed, so that different sides of the component can be irradiated, and the imager 46 rotates towards each other synchronously, so that synchronous imaging can be achieved on the imager 46, and then detection can be performed from different sides of the component, making the detection more comprehensive and reducing the probability of missed detection.
