Description

Technical Field

[0001] This utility model relates to the field of aluminum material testing technology, specifically to a device for detecting cracks in aluminum extrusion blanks. Background Technology

[0002] Cracking of aluminum extruded materials is a common quality problem in aluminum extrusion production. Failure to promptly identify cracks in the extruded material head can result in defective products flowing into the next process. This not only affects the appearance quality of the product but may also reduce its mechanical properties and service life. Traditional detection methods mostly rely on manual observation or simple mechanical inspection, which suffers from low efficiency and poor accuracy.

[0003] Therefore, existing technologies often use visual inspection devices for aluminum profiles to inspect aluminum extrusion heads. During inspection, it is often necessary to use fixtures to fix the aluminum profiles. Existing fixing methods mostly use bolt clamps, which can easily damage the fixing surface. Furthermore, using bolts for fixing is inconvenient to disassemble, resulting in complex operation.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an aluminum extrusion head crack detection device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A device for detecting cracks in aluminum extrusion blanks includes a working base plate, a transmission box located at the top center of the working base plate, clamp adjustment mechanisms located on both sides of the transmission box, camera assemblies located on both sides of the clamp adjustment mechanisms, and translation slide plates interlaced on both sides inside the clamp adjustment mechanisms; a fixed frame located at the top of the translation slide plates, a blank clamping mechanism located inside the fixed frame, and a blank loading platform located at the top of the transmission box.

[0008] Furthermore, in order to achieve stable support and electrical control of the working board, support legs are provided at the four corners of the bottom of the working board, and a control panel is provided on one side of the top of the working board.

[0009] Furthermore, in order to enable the lateral sliding of the two sliding plates by using the drive threaded rod to adjust the relative position of the fixed frame and meet the clamping and fixing of aluminum extrusion heads of different sizes and specifications; at the same time, the stability of the two sliding plates can be further improved by the cooperation of the worm gear and worm. The clamping adjustment mechanism includes fixed end plates set at the top of the working plate and located on both sides of the transmission box. Two lateral limiting rods and a drive threaded rod are set between the two fixed end plates. The drive threaded rod passes through the transmission box, and the part of the drive threaded rod inside the transmission box is fitted with a worm gear. A worm gear that cooperates with the worm gear is set at the top of the transmission box. A drive motor that cooperates with the worm gear is set on the outside of the transmission box. The sliding plate is inserted between the lateral limiting rods and the drive threaded rod, and the sliding plate and the drive threaded rod are threadedly connected.

[0010] Furthermore, in order to use the lifting top plate inside the fixed frame to clamp and fix the aluminum extrusion head below, ensuring the stability of the aluminum extrusion head during the crack detection process, and to center the aluminum extrusion head, thereby improving the accuracy of the visual inspection camera and increasing the detection precision, the head clamping mechanism includes a support base plate set at the bottom inside the fixed frame. Multiple lateral limiting rods are set between the two sides of the support base plate and the inner side wall of the fixed frame. Anti-deviation side plates are sleeved between the lateral limiting rods on the same side. A spring is sleeved on the outer circumference of the lateral limiting rods and between the anti-deviation side plate and the inner side wall of the fixed frame. An electric telescopic rod is set at the top of the fixed frame, and a lifting top plate connected to the output end of the electric telescopic rod is set at the top inside the fixed frame. The top of the support base plate and the bottom of the lifting top plate are both arc-shaped structures, and the anti-deviation side plate is a right-angled trapezoidal structure.

[0011] Furthermore, in order to improve the clamping effect of the material head and prevent the material head from sliding or shifting during the clamping and fixing process, the top of the material head platform is an arc-shaped structure, and several anti-slip grooves are provided at the top of the material head platform.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By designing a symmetrical structure with a relatively movable material head clamping mechanism, the aluminum extrusion head at the top of the material head platform can be adaptively clamped and fixed. That is, the distance of the material head clamping mechanism can be flexibly adjusted according to the structural information such as the length, width or size of the aluminum extrusion head itself, so as to meet the clamping and fixing of various aluminum extrusion heads. Then, through the camera components on both sides, the fixed aluminum extrusion head is visually inspected to identify cracks on the end face, thereby improving the inspection efficiency and accuracy of aluminum profiles.

[0014] 2. By setting up a support base plate and a lifting top plate distributed at the top and bottom, as well as anti-deviation side plates on both sides, the inserted fixed frame can be automatically and quickly clamped and fixed. Using the springs on both sides, the aluminum extrusion head inside can be centered and positioned, which is convenient for the camera component to take pictures and improves the detection accuracy.

[0022] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0023] According to an embodiment of the present invention, a crack detection device for aluminum extrusion blanks is provided.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, the aluminum extrusion head crack detection device according to an embodiment of the present invention includes a working base plate 1, a transmission box 2 is provided at the middle position of the top of the working base plate 1, a clamp adjustment mechanism 3 is provided on both sides of the transmission box 2, a camera assembly 4 is provided on both sides of the clamp adjustment mechanism 3, and a translation slide plate 5 is interspersed on both sides inside the clamp adjustment mechanism 3; a fixing frame 6 is provided at the top of the translation slide plate 5, a head clamping mechanism 7 is provided inside the fixing frame 6, and a head carrying platform 8 is provided at the top of the transmission box 2.

[0025] By utilizing the above technical solution, the aluminum extrusion head at the top of the material head platform 8 can be adaptively clamped and fixed by designing a symmetrical material head clamping mechanism 7 with relative motion. That is, the distance of the material head clamping mechanism 7 can be flexibly adjusted according to the structural information such as the length, width or size of the aluminum extrusion head itself, so as to meet the clamping and fixing of various aluminum extrusion heads. Then, the fixed aluminum extrusion head is visually inspected by the camera components 4 on both sides to identify cracks on the end face, thereby improving the inspection efficiency and accuracy of aluminum profiles.

[0026] In one embodiment, the working substrate 1 is provided with support legs 9 at the four corners of its bottom end and a control panel 10 is provided on one side of its top end, thereby enabling stable support and electrical control of the working substrate 1.

[0027] In one embodiment, the clamp adjustment mechanism 3 includes fixed end plates 301 disposed at the top of the working base plate 1 and located on both sides of the transmission box 2. Two transverse limiting rods 302 and a driving threaded rod 303 are disposed between the two fixed end plates 301. The driving threaded rod 303 passes through the transmission box 2, and a worm gear 304 is sleeved on the portion of the driving threaded rod 303 inside the transmission box 2. A worm 305 cooperating with the worm gear 304 is disposed at the top of the transmission box 2. A worm 305 is disposed on the outside of the transmission box 2. The drive motor 306, which works in conjunction with the worm gear 305, and the translation slide plate 5 are inserted between the lateral limiting rod 302 and the drive threaded rod 303. The translation slide plate 5 and the drive threaded rod 303 are threadedly connected, so that the drive threaded rod 303 can drive the translation slide plates 5 on both sides to slide laterally, thereby adjusting the relative position of the fixed frame 6 and satisfying the clamping and fixing of aluminum extrusion heads of different sizes and specifications. At the same time, the stability of the translation slide plates 5 on both sides can be further improved by the cooperation of the worm wheel 304 and the worm gear 305.

[0028] The working principle of the clamp adjustment mechanism 3 is as follows: The drive motor 306 drives the worm gear 305 to rotate, which in turn drives the worm wheel 304 to rotate. The worm wheel 304 is integrally set with the drive threaded rod 303, thus driving the drive threaded rod 303 to rotate. Then, the translation slide plates 5 on both sides of the drive threaded rod 303 slide on both sides of the drive threaded rod 303 under the action of the reverse thread, and finally drive the top fixed frame 6 to adjust, which can be adapted to the size of the aluminum extrusion head.

[0029] In one embodiment, the material head clamping mechanism 7 includes a support base plate 701 disposed at the bottom of the fixed frame 6. Multiple lateral limiting rods 702 are disposed between the two sides of the support base plate 701 and the inner wall of the fixed frame 6. Anti-deviation side plates 703 are sleeved between the lateral limiting rods 702 on the same side. Springs 704 are sleeved on the outer circumference of the lateral limiting rods 702 and between the anti-deviation side plates 703 and the inner wall of the fixed frame 6. An electric telescopic rod 705 is disposed at the top of the fixed frame 6. The top of the fixed frame 6 is equipped with a lifting top plate 706 connected to the output end of the electric telescopic rod 705. The top of the support base plate 701 and the bottom of the lifting top plate 706 are both arc-shaped structures, and the anti-deviation side plate 703 is a right-angled trapezoidal structure. Thus, the lifting top plate 706 inside the fixed frame 6 is used to clamp and fix the aluminum extrusion head below, ensuring the stability of the aluminum extrusion head during the crack detection process. It can also center the aluminum extrusion head, which can improve the accuracy of the visual inspection camera and improve the detection precision.

[0030] The working principle of the aluminum extrusion head clamping mechanism 7: After both ends of the aluminum extrusion head extend into the fixed frame 6, the electric telescopic rod 705 is driven to move downwards, causing the lifting top plate 706 to extend downwards until it contacts the top of the aluminum extrusion head, continuously clamping and fixing it downwards. During the descent of the head, a force is generated on the anti-deviation side plates 703 on both sides, pushing the anti-deviation side plates 703 to move to both sides. Due to the action of the spring 704, the anti-deviation side plates 703 will push the head towards the center position. Finally, the bottom of the head contacts the supporting base plate 701, and the lifting top plate 706 can no longer extend downwards, stopping the drive and achieving clamping and fixing.

[0031] In one embodiment, the top of the material head carrier 8 is an arc-shaped structure, and the top of the material head carrier 8 is provided with several anti-slip grooves 11, which can improve the clamping effect of the material head and prevent the material head from sliding and deviating during the clamping and fixing process.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] In practical applications, the aluminum extrusion head after aluminum profile extrusion is cut to a suitable size and placed on top of the head carrier 8, keeping the length of both sides of the head as equal as possible. Next, the clamp adjustment mechanism 3 is driven to change the position of the two fixing frames 6 until they cover both ends of the head. Then, the head clamping mechanism 7 is driven to clamp and fix the head, thus securing it. After fixing, the camera assembly 4 is driven to photograph and inspect both sides of the head, transmitting the images to an external computer. Through image processing and analysis, cracks in the head are identified. Furthermore, the camera assembly 4 itself can use a similar principle to the clamp adjustment mechanism 3 to adjust its lateral position, further enriching the application scenarios of the detection device and improving detection efficiency.

[0034] In summary, by utilizing the above-mentioned technical solution of this utility model, the aluminum extrusion head at the top of the material head platform 8 can be adaptively clamped and fixed by designing a symmetrical structure with relative motion of the material head clamping mechanism 7. That is, the distance of the material head clamping mechanism 7 can be flexibly adjusted according to the structural information such as the length, width, or size of the aluminum extrusion head itself, thereby meeting the clamping and fixing requirements of various aluminum extrusion heads. Furthermore, the fixed aluminum extrusion head can be visually inspected by the camera components 4 on both sides to identify cracks on the end face, thereby improving the inspection efficiency and accuracy of aluminum profiles. By setting up the vertically distributed support base plate 701 and lifting top plate 706, as well as the anti-deviation side plates 703 on both sides, the material head inserted into the fixing frame 6 can be automatically and quickly clamped and fixed. The springs 704 on both sides can center the aluminum extrusion head inside, facilitating the framing and shooting of the camera component 4 and improving the inspection accuracy.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
