Testing them during the construction process is a very intuitive and necessary quality inspection method. Among them, cross-section inspection is a commonly used quality inspection method. It judges the internal structure and organizational status of the aluminum alloy by observing the fracture characteristics, so as to judge its quality.

[0004] However, this patent still has certain shortcomings in actual use. First, when positioning the aluminum alloy profile sample, multiple clamping blocks need to be pushed at the same time, and these clamping blocks do not have a linkage structure, which leads to one or more of the clamping blocks being unable to be directly and stably pushed due to the smooth surface of the aluminum alloy profile during the actual pushing process. In addition, it is necessary to overcome the elastic force of multiple elastic parts at the same time during the pushing process. Its operation method is not convenient, which is not conducive to the rapid positioning of the aluminum alloy profile, thereby reducing the efficiency of subsequent detection. In this regard, the present application provides an aluminum alloy profile cross-section non-destructive testing instrument to solve the above problems. Utility Model Content

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] See also Figures 1 to 4 The present application provides a technical solution: an aluminum alloy profile cross-section non-destructive testing instrument, comprising a base 1, a positioning component 200 is installed on the top of the base 1, a detection component 300 is installed on the back of the base 1, and a limiting block 4 is fixed on the left side of the top of the base 1; through the cooperation between the positioning component 200 on the top of the base 1 and the detection component 300 on the outside, it is convenient to position the aluminum alloy profile and to replace different detection equipment for detection according to specific circumstances, so that the aluminum alloy profile sample can be quickly and conveniently put into the detection work, and different detection equipment can be replaced according to actual needs through the convenient limit between the structures, thereby facilitating the cross-section non-destructive testing work, greatly improving the detection efficiency, and integrating the data obtained by multiple non-destructive testing equipment to improve the detection accuracy, thereby effectively improving the practicality of the aluminum alloy profile cross-section non-destructive testing instrument, and giving it great room for promotion and application.

[0032] In this embodiment, the positioning assembly 200 is a structure for positioning the aluminum alloy profile.

[0033] like Figure 1 、 Figure 2 and Figure 4 As shown, the positioning assembly 200 includes an installation cavity 201 opened inside the base 1, a bidirectional screw 202 rotatably connected to the inner side of the installation cavity 201 through a bearing, two first slide rails 203 fixedly installed on the inner bottom wall of the installation cavity 201, two moving blocks 204 threadedly connected to the outer side of the bidirectional screw 202 and symmetrically distributed front to back, four first sliders 205 respectively slidably connected to the outer sides of the two first slide rails 203, an installation box 206 fixed to the front side of the base 1, a rotating shaft 207 fixed to one end of the front side of the bidirectional screw 202, a worm gear 208 sleeved on the outer side of the rotating shaft 207, a worm 209 rotatably connected to the inner side of the installation box 206 through a bearing, a knob 210 fixedly installed on the end of the worm 209, a fixed plate 211 fixed to the top of the moving block 204, and two splints 212 respectively fixed to the top of the two fixed plates 211 close to each other.

[0034] It should be noted that the opposite sides of the two corresponding first sliders 205 are fixedly connected to the left and right sides of the corresponding moving block 204 respectively, and the first slide rail 203 can be a linear guide rail used for industrial equipment, so that the first slider 205 can only perform linear motion on the outer side of the corresponding first slide rail 203 and cannot be detached, so that the moving block 204 can perform smooth linear motion under the limited sliding action of the two corresponding first sliders 205, and the front end of the rotating shaft 207 passes through the front of the base 1 and extends to the interior of the installation box 206. The front end of the rotating shaft 207 is rotatably connected to the inner front side wall of the installation box 206 through a bearing, so that the rotating shaft 207 can rotate stably.

[0035] In addition, the outer side of the worm 209 is meshed with the outer side of the worm wheel 208, and the output shaft of the knob 210 passes through the left side of the mounting box 206 and is fixedly connected to the left end of the worm 209, so that the knob 210 can drive the worm 209 to rotate and the worm wheel 208 to rotate. The top of the base 1 is provided with two moving holes for the two moving blocks 204 to slide respectively and connected to the inside of the mounting cavity 201, so that the moving blocks 204 can slide normally on the inner side of the corresponding moving holes.

[0036] At the same time, rubber pads are bonded to the opposite sides of the two clamps 212, and three triangular frames are fixed between the clamps 212 and the opposite sides of the corresponding fixing plates 211, which can provide auxiliary support for the clamps 212 and facilitate stable clamping and positioning.

[0037] In this embodiment, the detection component 300 is a structure for detecting aluminum alloy profiles.

[0038] like Figure 1 and Figure 3 As shown, the detection component 300 protects an equipment box 301 fixedly installed on the back of the base 1, an extension plate 302 fixed on the front of the equipment box 301, a second slide rail 303 fixedly installed at the bottom of the extension plate 302, a second slider 304 slidably connected to the outside of the second slide rail 303, a connector 305 fixed to the bottom of the second slider 304, a T-shaped slot 306 opened on the front side of the connector 305, a T-shaped slider 307 slidably connected to the inside of the T-shaped slot 306, and a detection device body 308 fixedly installed at the bottom of the T-shaped slider 307.

[0039] It should be noted that an auxiliary rod is fixed to the top of the extension plate 302, and stretching rods are fixed between the two ends of the top of the second slide rail 303 and the outer side of the auxiliary rod, so that the stretching rod can play the role of auxiliary stretching support for the second slide rail 303, wherein the second slide rail 303 can be a linear guide rail for industrial equipment, and the bottom of the T-shaped slide groove 306 is set to be open, so that the T-shaped slider 307 can slide normally to the inner side of the T-shaped slide groove 306.

[0040] In addition, the T-shaped slider 307 and the connecting member 305 are detachably connected through a locking member, which is a bolt and a nut. The end of the bolt passes through the connecting member 305 and the left side of the T-shaped slider 307 in sequence, and the nut is threadedly connected to the outside of the bolt and abuts against the right side of the connecting member 305, so that the T-shaped slider 307 can be detachably connected to the connecting member 305 through the cooperation between the bolt and the nut, which facilitates the replacement of the T-shaped slider 307 and the detection equipment body 308.

[0041] At the same time, the detection device body 308 is an ultrasonic detector or a radiation detector. Specifically, the detection device body 308 can be an ultrasonic detector, a radiation detector, an infrared thermal detector, an eddy current detector, etc. Ultrasonic detection can use the reflection and refraction of ultrasonic waves after emission to detect defects. The radiation detector uses X-rays or gamma rays to penetrate materials and identifies the internal structure of the material by detecting the change in radiation intensity after penetration. The infrared thermal detector uses the difference in thermal conductivity between the material and air to detect the internal structure morphology. The eddy current detector uses the eddy currents generated in the conductive material by the alternating magnetic field to identify material defects by detecting the change in eddy currents. At the same time, it can also be other non-destructive testing equipment that can detect within a specified range. Therefore, by alternating use of the above-mentioned detection device body 308, the cross-section of the aluminum alloy profile can be inspected with high precision. At the same time, the detection device body 308 can be replaced with a hydraulic cylinder and a pressure sensor that guide the T-shaped slider 307, so that the compressive strength and hardness of the surface of the aluminum alloy profile can be tested, thereby effectively improving the scope of application of this non-destructive testing instrument.

[0042] It should also be noted that the device box 301 is internally integrated with a main controller, which is a computer host for processing signal data. A control panel is fixedly installed on the back of the device box 301. The detection device body 308 can be connected to the main controller using a data cable. The connection method of the data cable or wire is an existing public technology, so it will not be elaborated on.

[0043] The working principle of the above embodiment is:

[0044] When inspecting the cross section of the aluminum alloy profile, the aluminum alloy profile sample is placed on the top of the base 1, and its end is abutted against the right side of the limit block 4. The knob 210 is turned to drive the worm 209 to rotate and the worm wheel 208 to be selected, thereby rotating the shaft 207. The two moving blocks 204 can move towards or away from each other through the threaded transmission action of the bidirectional screw 202, and the aluminum alloy profile sample is clamped and positioned by the two clamping plates 212. The corresponding detection device body 308 is slidably connected to the inner side of the T-shaped slide groove 306 through the T-shaped slider 307. After the installation of the detection device body 308 is completed, the connecting piece 305 can be pushed to make the second slider 304 slide on the outer side of the second slide rail 303, so that the detection device body 308 can detect any position of the aluminum alloy profile sample, and different detection methods can be achieved by replacing different detection device bodies 308, thereby obtaining high-precision detection data.

[0045] Compared with the existing technology, the aluminum alloy profile cross-section non-destructive testing instrument, through the coordinated use between the positioning component 200 on the top of the base 1 and the detection component 300 on the outside, can facilitate the positioning of the aluminum alloy profile while also facilitating the replacement of different detection equipment for testing according to specific circumstances, so that the aluminum alloy profile sample can be quickly and conveniently put into the testing work, and different detection equipment can be replaced according to actual needs through convenient limiters between structures, thereby facilitating the cross-section non-destructive testing work, greatly improving the testing efficiency, and integrating the data obtained by multiple non-destructive testing equipment to improve the accuracy of the detection, thereby effectively improving the practicality of the aluminum alloy profile cross-section non-destructive testing instrument, giving it a huge space for promotion and application, and solving the shortcoming of the existing aluminum sample testing instrument in the actual operation process that the positioning method of the aluminum alloy profile is not convenient.

[0046] The electrical components appearing in this article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in this field. The main controller can be a conventional known device that controls a computer, etc., and can be implemented through simple programming by technicians in this field. These are all existing publicly available power connection technologies and will not be described in detail in this article.
