Description

Technical Field

[0001] The present invention relates to the technical field of finished product inspection, and particularly relates to a surface defect detection device for machined finished products. Background Art

[0002] The inner surface inspection technology of pipe fittings is an important quality control means in the industrial field. Especially in industries such as manufacturing, chemical industry, oil and gas, and aerospace, the quality of the pipeline system is directly related to the safety and operation efficiency of the equipment. There may be various defects on the inner surface of pipe fittings, such as corrosion, scratches, cracks, deposits, welding defects, etc. These defects will affect the fluid transportation capacity, durability, and safety of the pipeline. Therefore, the research and application of the inner surface inspection technology of pipe fittings have become crucial.

[0003] In the literature (publication number: CN116626066B), a surface defect detection device and method for machined finished products are disclosed. This device transports the machined finished products that need to be inspected for surface defects to a predetermined position through a conveying device, and sequentially clamps and positions the inner and outer surfaces of the machined finished products through a clamping and limiting device. After the clamping and fixing are completed, the defect detection is sequentially carried out on the outer and inner surfaces of the machined finished products through a detection device, completing the defect detection of the inner and outer surfaces of the annular machined finished products, improving the efficiency of the detection process, and shortening the detection time. This solution can improve the clamping efficiency of the surface of the machined finished products, shorten the surface defect detection time, and improve the detection efficiency; at the same time, it can also provide flexible protection for the surface of the machined finished products to ensure the quality of the finished products. However, when detecting workpieces with internal bends, this device cannot meet the detection of the curved surface, resulting in limitations of this device, being unable to reasonably meet different detection requirements, and also unable to avoid the influence of external light sources on the detection results during actual use, reducing the accuracy of the detection of this device.

[0016] The beneficial effects of the present invention are as follows:

[0017] In the present invention, a servo motor two drives a rotating plate to rotate, causing an airbag one, a hard brush, and a limiting plate to rotate along with the rotating plate. When the airbag one expands, the hard brush fits against the inner surface of the workpiece to remove impurities on the inner surface of the workpiece. A connecting frame enables a driven plate to rotate along with the rotating plate. When the driven plate rotates, three sets of gears two rotatably connected to one side thereof rotate self - by means of a gear ring two, causing threaded rods fixedly connected to the surfaces of the gears two to rotate. As a result, sliders two thread - connected to the surfaces of the threaded rods move horizontally along the inner walls of brackets two, changing the angle between a reflecting mirror and a fixed rod. Thus, the position of the inner surface of the workpiece reflected by the reflecting mirror extends or contracts, enabling an industrial camera to detect the inner surfaces at different positions. This structural arrangement effectively avoids the problem that the camera needs to penetrate to the bottom of the workpiece during workpiece detection and can achieve the effect of assisting the camera in detection through the reflecting mirror surface. At the same time, it can clean the inner surface of the workpiece before detection, removing defects such as oil stains and burrs on the inner surface of the workpiece, improving the qualification rate of the workpiece, enhancing the accuracy of detection, and reducing the time required for detection.

[0018] In the present invention, by filling gas into an airbag two, the airbag two expands, generating a horizontal tensile force, causing each set of adjusting pipes to move horizontally along with the airbag two, exposing the flexible hoses. Due to the flexibility of the hoses, components on one side of the adjusting pipes can bend, enabling the detection mechanism to enter the bent part of the workpiece. After the detection is completed, a wire winder is used to recover the adjusting rope, pulling the detection mechanism out of the bent part. Continuing to pull the adjusting rope makes each set of adjusting pipes lie in the same horizontal plane. As the adjusting rope gradually contracts, each set of adjusting pipes gradually return to their original positions and are mutually clamped, placing the detection mechanism and other components in the same horizontal plane. This structural arrangement effectively avoids the problem that the bent part of the workpiece cannot be detected and can achieve the effect of detecting the bent part of the workpiece. At the same time, it improves the functionality of the device, reduces the time required for detecting the inner surface of the workpiece, enhances the corresponding detection efficiency, and can also improve the convenience of the device during actual use.

[0019] In the present invention, an electric telescopic rod two drives an adjusting block to move horizontally along the inner wall of a connecting rod one. Three sets of connecting blocks two enable a slider three to move horizontally along with the adjusting block, changing the angle between an adjusting rod and the slider three, and further changing the angle between a connecting rod two and a receiving block, causing three sets of auxiliary wheels to all fit against the inner surface of the workpiece. This structural arrangement effectively avoids the problem that the device cannot detect the symmetry of the workpiece during detection and can achieve the effect of detecting whether the workpiece is centrosymmetric. At the same time, it improves the functionality of the device, enhances the accuracy of detection, reduces the time required for subsequent detection, and improves the corresponding detection efficiency.

Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] Embodiment 1, as Figures 1 - 11As shown in the figure, a surface defect detection device for machined finished products includes a driven plate 315. On one side of the driven plate 315, there is a detection mechanism 3. The detection mechanism 3 includes a second support 31, a threaded rod 32, a second gear 33, a second toothed ring 34, a connecting frame 35, a second slider 39 and a rotating plate 54. The second support 31 is fixedly connected to the driven plate 315. The second gear 33 is rotatably connected to the driven plate 315. The second gear 33 meshes with the second toothed ring 34. The second gear 33 is fixedly connected to the threaded rod 32. The threaded rod 32 is threadedly connected to the second slider 39. The second slider 39 is slidably connected to the second support 31. The connecting frame 35 is fixedly connected to the driven plate 315. The connecting frame 35 is fixedly connected to the rotating plate 54. On one side of the second slider 39, there is a first hinge seat 38 fixedly installed. Inside the first hinge seat 38, there is a reflecting mirror 36 rotatably connected. On one side of the driven plate 315, there is a fixed rod 37 fixedly connected. At one end of the fixed rod 37, there is a second hinge seat 310 fixedly installed. The second hinge seat 310 is rotatably connected to the reflecting mirror 36. On one side of the second hinge seat 310, there is a fixed frame 313 fixedly connected. On the surface of the fixed frame 313, there are three groups of fixed blocks 312 fixedly connected. Inside each of the three groups of fixed blocks 312, there is an industrial camera 311 fixedly installed. Inside the fixed block 312, there is a soft light box 314;

[0034] On one side of the driven plate 315, there is a cleaning mechanism 5. The cleaning mechanism 5 includes an adjusting rope 56, a second airbag 55, a hose 510, an adjusting pipe 59 and a wire winder 57.

[0035] When detecting a tubular workpiece, the outer surface is usually detected by rotating the workpiece. Since some tubular workpieces have bent parts, it is difficult to effectively detect the bent parts when detecting the inner surface. Moreover, when detecting the inner surface, the external light source will also affect the normal detection. When detecting the inner surface of a tubular workpiece, first, the workpiece is transported to the upper surface of the detection platform 2 through the feeding belt 11. The first electric telescopic rod 25 is started, and the first slider 26, the bearing plate 27, the hydraulic rod 28, the first connecting block 29 and the first connecting rod 210 are horizontally moved through the first electric telescopic rod 25, so as to fit the detection device with one end of the workpiece. The first airbag 51 is inflated to make the hard brush 53 fit with the workpiece, so that the workpiece and the detection device are on the same horizontal plane. The detection platform 2 is rotated by starting the first servo motor 21, so as to move the workpiece to the fixing plate 17. The workpiece is lifted by the hydraulic rod 28, so that the workpiece and the fixing plate 17 are on the same horizontal plane. The workpiece is made to fit with the fixing plate 17 through the first electric telescopic rod 25. The cleaning liquid is sprayed into the inner wall of the workpiece through the nozzle 13. The hard brush 53 is slowly rotated by the second servo motor 58, and the burrs, oil stains, etc. on the inner wall of the workpiece are removed by the hard brush 53. The detection mechanism 3 is gradually moved deeper into the workpiece. At this time, the elastic plate 4 fits with the inner wall of the workpiece. The limiting air pipe 45 is inflated through the air delivery pipe 44, so that there is no gap between the elastic plate 4 and the workpiece. Thus, the impurities cleaned are gradually pushed by the air delivery pipe 44. The driven plate 315 can rotate along with the rotating plate 54 through the connecting frame 35. When the driven plate 315 rotates, the three groups of second gears 33 rotatably connected to one side of it rotate selflessly through the second gear ring 34, so that the threaded rod 32 fixedly connected to the surface of the second gear 33 rotates, and the second slider 39 threadedly connected to the surface of the threaded rod 32 moves horizontally along the inner wall of the second bracket 31, so that the included angle between the reflecting mirror 36 and the fixed rod 37 changes. Thus, the position of the inner surface of the workpiece reflected by the reflecting mirror 36 is extended or contracted, and further, the industrial camera 311 can detect the inner surface at different positions. When moving to the bent part, the second airbag 55 is inflated by filling gas into the second airbag 55, so that the second airbag 55 generates a horizontal tensile force, so that each group of adjusting pipes 59 moves horizontally along with the second airbag 55, so that the flexible hose 510 is exposed outside. Due to the flexibility of the flexible hose 510, the components on one side of the adjusting pipe 59 can be bent, so that the detection mechanism 3 can enter the bent part of the workpiece. After the detection is completed, the adjusting rope 56 is recycled by the wire winder 57, so as to pull the detection mechanism 3 out of the bent part. The adjusting rope 56 is continuously pulled, so that each group of adjusting pipes 59 are on the same horizontal plane. As the adjusting rope 56 gradually contracts, each group of adjusting pipes 59 gradually return to their original positions, so that each group of adjusting pipes 59 are clamped with each other, so that the detection mechanism 3 and other components are on the same horizontal plane, thus completing the detection of the inner surface of the workpiece.

[0036] Example 2, as Figure 10 and Figure 11 shown, on the basis of the above embodiments, it further includes that the adjusting pipe 59 is fixedly connected to the second gear ring 34, the adjusting pipe 59 is slidably connected to the flexible pipe 510, the second airbag 55 is attached to the flexible pipe 510, the adjusting rope 56 is attached to the second airbag 55, one end of the adjusting rope 56 is fixedly connected to the wire reel 57, and the other end of the adjusting rope 56 is fixedly connected to the adjusting pipe 59. Through this structure, the detection mechanism 3 can be softly separated from the subsequent device, enabling the detection mechanism 3 to detect the bent part of the workpiece, thereby improving the functionality of the device.

The inner wall burrs, oil stains and rust of the workpiece can be removed by the hard brushes 53, so that the problems of the workpiece itself can be processed before detection, further improving the qualified rate of the workpiece.

The limiting air pipe 45 is inflated through the air delivery pipe 44, so that there is no gap between the elastic plate 4 and the workpiece. Thus, the impurities after cleaning are gradually pushed by the air delivery pipe 44, so that the inner wall after cleaning can be wiped, improving the cleanliness of the inner surface of the workpiece.

Through the three groups of second connecting blocks 46, the third slider 49 follows the adjusting block 413 to move horizontally, so that the included angle between the adjusting rod 411 and the third slider 49 changes, and then the included angle between the second connecting rod 47 and the receiving block 42 changes, so that all three groups of auxiliary wheels 41 are in contact with the inner surface of the workpiece, thereby being able to detect the symmetry of the workpiece and increasing the functions of the device.
