Description
Technical Field
[0001] This application relates to the field of detection equipment, and in particular, to a roll surface flaw detection device. Background Art
[0002] Currently, most enterprises use automatic eddy current detection equipment to detect surface defects of rolls. According to the principle of eddy current flaw detection, eddy currents are interfered and affected by many factors such as the chemical composition, hardness heat treatment conditions, and crack direction of the test piece. Therefore, false flaw signals often occur during detection.
[0003] Moreover, current roll detection devices are all highly comprehensive detection equipment, which are easily affected by various factors. Subtle changes in process parameters may also greatly reduce the performance of the detection equipment. Summary of the Invention
[0004] In order to conveniently detect the surface of rolls and improve the detection efficiency, this application provides a roll surface flaw detection device.
[0005] The roll surface flaw detection device provided by this application adopts the following technical solutions: A roll surface flaw detection device includes a base. A support assembly for supporting the roll is provided on the base. A drive assembly for driving the roll to rotate is provided on the support assembly. A cover covering the base is further provided on the base. A laser emitter is provided on the side of the cover facing the roll, and a receiving plate for receiving the reflected laser is provided on the cover.
[0006] By adopting the above technical solutions, the roll is placed flat on the base through the support assembly, and then the cover is installed on the base, so that the roll is covered therein. The laser emitter irradiates the surface of the roll with laser, and the laser reaches the receiving plate after being reflected by the surface of the roll. Thus, the surface information of the roll is observed and recorded. If the reflected laser is straight, it means the roll surface is smooth. If the reflected laser is zigzag, it means there are defects on the roll surface. At the same time, the drive assembly drives the roll to rotate, thereby detecting the circumferential surface of the roll, making the roll surface flaw detection fast and convenient, and improving the detection efficiency.
[0007] Optionally, the support assembly includes two elevators provided on the base. A support block driven by the elevators is provided above the elevators, and the drive assembly is provided on the support block.
[0008] By adopting the above technical solutions, the roll is placed on the support block and simultaneously contacts the drive assembly. Thus, the drive assembly can drive the roll to rotate, and at the same time, the elevators can lift the height of the roll, thereby corresponding to rolls of different diameter sizes, enabling various rolls to be detected and improving the applicability of the flaw detection device.
[0009] Optionally, the support block is slidably connected to the elevator, and a buffer spring is provided between the support block and the elevator. V-shaped rods are hinged at both ends of the support block. One end of each V-shaped rod is hinged to a connecting rod, and at the same time, the connecting rod is hinged to the elevator, and a pressing wheel is provided at the other end.
[0010] By adopting the above technical solution, when the rolling roll presses on the support block, the rolling roll presses the support block to slide downward, and at the same time compresses the buffer spring. At this time, the support block drives the V-shaped rod to move, and the V-shaped rod rotates under the support of the connecting rod, so that the pressing wheel on the V-shaped rod presses on the rolling roll, thereby preventing the rolling roll from shaking easily.
[0011] Optionally, the side of the support block close to the rolling roll is set as a downwardly concave arc surface. The driving assembly includes a driving wheel rotatably connected to the support block. The driving wheel is located at the bottom of the arc surface and is used to support the rolling roll. A driving motor for driving the driving wheel to rotate is provided on the support block.
[0012] By adopting the above technical solution, the rolling roll is placed on the arc surface and presses on the driving wheel. The driving motor drives the driving wheel to rotate, thereby driving the rolling roll to rotate, and the surface of the rolling roll is detected during the rotation of the rolling roll.
[0013] Optionally, a cleaning assembly for cleaning the surface of the rolling roll is provided inside the enclosure. The cleaning assembly includes a support plate provided on the enclosure and parallel to the axis of the rolling roll. A plurality of positioning rods arranged side by side are provided on the support plate. A sliding rod is slidably connected to the positioning rods. One end of the sliding rod close to the rolling roll is rotatably connected to a rotating rod, and a rotary brush is provided on the rotating rod. A positioning bolt is threadedly connected to the positioning rod, and the positioning bolt abuts against the sliding rod.
[0014] By adopting the above technical solution, according to the size of the rolling roll, loosen the positioning bolt, thereby moving the sliding rod so that the rotary brush moves to the side wall at the corresponding position of the rolling roll, and then tighten the positioning bolt again, so that the rotary brush can clean the surface of the rolling roll, reducing the influence on the surface flaw detection of the rolling roll due to the adhesion of impurities on the rolling roll.
[0015] Optionally, a scraper is also hinged inside the enclosure. A torsion spring is also provided between the scraper and the enclosure. A folding plate is fixedly connected to the side of the scraper close to the rolling roll, and the folding plate abuts against the side wall of the rolling roll.
[0016] By adopting the above technical solution, during the rolling process of the rolling roll, the scraper simultaneously scrapes the surface of the rolling roll, thereby cleaning the impurities adhered to the rolling roll. Among them, the torsion spring makes the scraper always keep abutting against the side wall of the rolling roll, further improving the cleaning effect of the surface of the rolling roll.
[0017] Optionally, a cavity is opened inside the base, a dust suction hole facing the rolling roll is opened on the base, and an exhaust fan communicating with the cavity is also provided on the base.
[0018] By adopting the above technical solution, the exhaust fan sucks the impurities cleaned from the roll into the cavity through air extraction, thereby concentrating the impurities, facilitating cleaning, and reducing the possibility of the impurities flying in the enclosure and adhering to the roll again.
[0019] Optionally, one end of the rotating rod is provided with a cross groove, and the other end is provided with a cross key that cooperates with the cross groove. The adjacent rotating rods are connected through the cross groove and the cross key. A cable is also provided between the two separated rotating rods to connect the two. A rotating motor for driving the rotating rod to rotate is further provided on the enclosure.
[0020] By adopting the above technical solution, when the rotating motor drives one rotating rod to rotate, the rotating rod drives all the rotating rods to rotate through the cross key, the cross groove and the cable, so that the roller brush cleans the surface of the roll.
[0021] In summary, the present application includes at least one of the following beneficial technical effects: The laser emitter irradiates the surface of the roll with laser, and the laser reaches the receiving plate after being reflected by the surface of the roll. Thus, the surface information of the roll is observed and recorded. If the reflected laser is straight, it means the surface of the roll is smooth. If the reflected laser is zigzag, it means there are defects on the surface of the roll. At the same time, the driving component drives the roll to rotate, thereby detecting the circumferential surface of the roll, making the surface flaw detection of the roll fast and convenient and improving the detection efficiency; The cleaning component removes impurities from the surface of the roll, thereby reducing the influence of impurities on the detection result of the surface flaw detection of the roll and improving the detection accuracy.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] The following further describes the present application in conjunction with the accompanying drawings.
[0027] An embodiment of the present application discloses a surface flaw detection device for a roll. Referring to Figure 1 and Figure 2 , a surface flaw detection device for a roll includes a base 1. A circular groove is provided at the edge of the base 1 and distributed along the edge of the base 1. A cover 2 is provided on the base 1, and the edge of the cover 2 is inserted into the groove. A detection component for detecting the surface of the roll is further provided on the cover 2.
[0028] A support component 3 is provided at the upper end of the base 1 for supporting the roll. The support component 3 includes a pair of elevators 31, which are distributed at both ends of the base 1. A support block 32 is provided above the elevator 31. A chute 321 is provided at the end of the support block 32 facing the elevator. A buffer spring 322 is fixedly connected in the chute 321, and the buffer spring 322 abuts against the elevator 31 at the same time.
[0029] The end of the support block 32 away from the elevator 31 is set as an arc surface, and the arc surface gradually depresses towards the end close to the elevator 31 from both ends to the middle. A driving component 4 for driving the roll to rotate is further provided on the support block 32.
[0030] According to the diameter of the roll, the elevator 31 adjusts the height of the support block 32 so that the support block 32 keeps the roll in a suspended state when supporting the roll, thereby corresponding to rolls of different diameter sizes. The roll is placed on the support block 32 and moves along the arc surface to the bottom of the arc surface, thereby stabilizing the position of the roll. At the same time, the roll contacts the driving component 4, and the driving component 4 drives the roll to rotate, and the detection component then detects the surface of the roll.
[0031] The detection component includes a linear laser emitter 21, which is installed at the upper end inside the cover 2 and faces the surface of the roll. A semi-transparent receiving plate 22 is provided on the upper end surface of the cover 2, and the receiving plate 22 is electrically connected to a controller at the same time and can record the shape of the reflected laser.
[0032] The roll is placed flat on the base 1 through the support component 3, and then the cover 2 is installed on the base 1 so that the roll is covered therein. The laser emitter 21 irradiates the roll surface with laser, and the laser reaches the receiving plate 22 after being reflected by the roll surface. Thus, the surface information of the roll is observed and recorded. If the reflected laser is a straight line, it means the roll surface is smooth. If the reflected laser is tortuous, it means there are defects on the roll surface. At the same time, the driving component 4 drives the roll to rotate, and then the circumferential surface of the roll is detected.
[0033] The driving assembly 4 includes a driving wheel 41 rotatably connected to the support block 32. The driving wheel 41 is located at the bottom of the arc surface and abuts against the lower end surface of the rolling mill roll. A driving motor 42 for driving the driving wheel 41 to rotate is installed on the support block 32. The driving motor 42 drives the driving wheel 41 to rotate, and the driving wheel 41 drives the rolling mill roll to rotate through friction, thereby realizing the circumferential surface detection of the rolling mill roll.
[0034] To improve the stability of the rolling mill roll, V-shaped rods 323 are hinged at both ends of the support block 32. One end of the V-shaped rod 323 is hinged with a connecting rod 324. The end of the connecting rod 324 far from the V-shaped rod 323 is hinged with a fixing frame 33. The fixing frame 33 is installed on the base 1 and is hinged with the elevator 31. A pressing wheel 325 is rotatably connected to the end of the V-shaped rod 323 far from the connecting rod 324.
[0035] When the rolling mill roll presses on the support block 32, the rolling mill roll presses the support block 32 to slide downward, and at the same time compresses the buffer spring 322. At this time, the support block 32 drives the V-shaped rod 323 to move. The V-shaped rod 323 rotates under the support of the connecting rod 324, so that the pressing wheel 325 on the V-shaped rod 323 presses on the rolling mill roll, thereby preventing the rolling mill roll from shaking easily.
[0036] Refer to Figure 1 and Figure 3 As shown in [relevant figure numbers], a cleaning assembly 5 for cleaning the surface of the rolling mill roll is provided in the enclosure 2. The cleaning assembly 5 includes a support plate 51 fixed in the enclosure 2 and parallel to the axis of the rolling mill roll. A plurality of positioning rods 52 arranged side by side are provided on the support plate 51. A sliding rod 53 facing the rolling mill roll is slidably connected to the positioning rod 52. One end of the sliding rod 53 close to the rolling mill roll is rotatably connected to a rotating rod 54. A rolling brush 55 is installed on the rotating rod 54. A positioning bolt is threadedly connected to the positioning rod 52, and the positioning bolt abuts against the sliding rod 53.
[0037] Loosen the positioning bolt, thereby moving the sliding rod 53 so that the rolling brush 55 moves to the side wall at the corresponding position of the rolling mill roll, and then tighten the positioning bolt again so that the rolling brush 55 can clean the surface of the rolling mill roll.
[0038] One end of the rotating rod 54 is provided with a cross groove, and the other end is provided with a cross key matching the cross groove. The adjacent rotating rods 54 are connected through the cross groove and the cross key. A cable connecting the two is also provided between the two separated rotating rods 54. A rotating motor for driving the rotating rod 54 to rotate is also provided on the enclosure 2. When the rotating motor drives one rotating rod 54 to rotate, the rotating rod 54 drives all the rotating rods 54 to rotate through the cross key, the cross groove and the cable, so as to make the rolling brush 55 clean the surface of the rolling mill roll.
[0039] Inside the cover 2, there is also a scraping plate 56 hinged. A torsion spring is also provided between the scraping plate 56 and the cover 2. A folding plate is fixedly connected to the side of the scraping plate 56 close to the rolling mill roll. The folding plate abuts against the side wall of the rolling mill roll. During the rolling process of the rolling mill roll, the scraping plate 56 simultaneously scrapes the surface of the rolling mill roll, thereby cleaning the impurities adhered to the rolling mill roll. Among them, the torsion spring enables the scraping plate 56 to always keep abutting against the side wall of the rolling mill roll, further improving the cleaning effect of the surface of the rolling mill roll.
[0040] In addition, a cavity is opened inside the base. A dust suction hole 11 facing the rolling mill roll is opened on the base. An air extractor communicating with the cavity is also provided on the base. By extracting air, the air extractor sucks the impurities cleaned from the rolling mill roll into the cavity, thereby concentrating the impurities, facilitating cleaning, and reducing the possibility that the impurities fly in the cover 2 and adhere to the rolling mill roll again.
[0041] The implementation principle of an embodiment of a rolling mill roll surface flaw detection device in the application is as follows: Open the cover 2, place the rolling mill roll on the support block 32, then cover the cover 2 on the base 1 again. The driving motor 42 drives the rolling mill roll to rotate, and at the same time, the rotating motor drives the brush 55 to rotate. At this time, the impurities on the surface of the rolling mill roll are cleaned. Then, the laser emitter 21 is turned on to detect the surface of the rolling mill roll.
[0042] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
