Description

Technical Field

[0001] The invention relates to the technical field of laser rust removal, and in particular to a laser rust removal device for a shield machine with a dust suction structure. Background Art

[0002] The cutter of a shield machine is a key component used to crush rocks and soil during tunnel excavation. Due to long-term work in harsh underground environments, rust, mud and other sediments are easily accumulated on the surface of the cutter, which not only affects the working efficiency of the cutter, but also shortens its service life. Therefore, it is very necessary to regularly remove rust and maintain the cutter of a shield machine. The rust removal methods for the cutter of a shield machine include mechanical rust removal, sandblasting rust removal, chemical rust removal and laser rust removal. Laser rust removal is widely used due to its advantages of precise control of the rust removal area and little damage to the substrate. However, the existing laser rust removal device always removes rust on the cutter of a shield machine in a horizontal state when removing rust from the cutter. As a result, when the laser is removing rust from the blade of the cutter, due to the change in radius at the blade, the laser jet direction and the angle of the rust surface at the blade are tilted, resulting in a decrease in the angle between the laser and the rust surface, an increase in the degree of laser scattering, and a decrease in the absorption of laser energy by the rust surface, resulting in poor rust removal effect.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The existing laser rust removal device always removes rust from the shield machine cutter in a horizontal state, resulting in that when the laser is removing rust from the cutting edge of the cutter, due to the change in radius at the cutting edge, the laser spray direction and the angle of the rust surface at the cutting edge are tilted, resulting in a decrease in the angle between the laser and the rust surface, an increase in the degree of laser scattering, and a decrease in the absorption of laser energy by the rust surface, thereby reducing the rust removal effect.

[0031] Example 1: A laser rust removal device for a shield machine with a dust suction structure, combined with Figure 1-Figure 4As shown, it includes a support frame 1, the top of the support frame 1 is slidably connected to a slider located at the top through an electric slide rail, the slider on the top of the support frame 1 and its bottom are rotatably connected to a fixed platform 2 through a connecting piece, the rear side and the left side of the support frame 1 are slidably connected to a first sliding block 3 through an electric slide rail, the upper planes of the two mirror-distributed first sliding blocks 3 are fixedly connected to a first telescopic rod 4, [the first telescopic rod 4 is composed of a piston shaft (telescopic end), a sleeve (fixed part) and a spring therebetween, the spring is used to drive the piston shaft to reset, and the closed cavity between the piston shaft and the sleeve is filled with hydraulic oil, the telescopic rods appearing in the whole text are all set for this purpose, and will not be repeated below], the telescopic end of the first telescopic rod 4 A detection head 5 is fixedly connected, and the detection head 5 fits the four points of the cross section of the hob. The first sliding block 3 is slidably connected to a rotating cylinder 6. The central axis of the rotating cylinder 6 is highly consistent with the central axis of the adjacent detection head 5 and is parallel to each other. A first flexible tube 7 is fixedly connected between the rotating cylinder 6 and the fixed part of the adjacent first telescopic rod 4. The first flexible tube 7 has sufficient margin to adapt to the position change between the adjacent rotating cylinder 6 and the adjacent first telescopic rod 4. The first flexible tube 7 is filled with hydraulic oil. A first dust suction head 8 is fixedly connected to the rotating cylinder 6. The first dust suction head 8 is used to absorb the smoke and dust generated during rust removal. A fixed plate 9 is fixedly connected to the inside of the rotating cylinder 6. The rotating cylinder 6 is rotatably connected to a rotating inner shaft 10, and the rotating inner shaft 10 is fixedly connected to a sliding plate 9. The movable plate 11 and the sliding plate 11 are located inside the adjacent rotating cylinder 6. The rotating cylinder 6, the adjacent fixed plate 9, the adjacent rotating inner shaft 10 and the adjacent sliding plate 11 cooperate to form a closed cavity, and the closed cavity is filled with hydraulic oil. The fixed part of the first telescopic rod 4 is connected to the adjacent closed cavity through the adjacent first flexible tube 7. The detection head 5 is driven by the change of the radius of the hob to push the telescopic end of the adjacent first telescopic rod 4 to slide along its fixed part, so that the hydraulic oil in the fixed part of the first telescopic rod 4 enters the adjacent closed cavity along the adjacent first flexible tube 7. The rotating inner shaft 10 is fixedly connected with a first laser head 12. The first laser head 12 is a focusing laser nozzle. The laser spraying direction of the first laser head 12 is the same as that of the adjacent detection head 5. The central axis of the rotating cylinder 6 is vertically cross-distributed, and the fixed plates 9 in the two mirror-distributed rotating cylinders 6 are respectively located on the opposite sides of the sliding plates 11 on the adjacent rotating inner shafts 10, so as to make the two mirror-distributed first laser heads 12 rotate in opposite directions. The mirror-distributed first sliding blocks 3 are each provided with a stabilizing component for stabilizing the height of the adjacent first laser heads 12. The radius change of the hob is detected by the detection head 5, so that the first laser head 12 is rotated accordingly, and the laser spraying direction of the first laser head 12 is changed so that the laser spraying direction is perpendicular to the rust surface of the hob, so as to avoid the spraying angle of the first laser head being too fixed, and the deviation of the spraying angle of the rust surface of the blade from the first laser head being too large, thereby enhancing the rust removal effect on the rust surface of the blade.

[0032] Combination Figure 2As shown, the stabilizing assembly includes a second telescopic rod 13 (the internal structure of the second telescopic rod 13 is the same as that of the first telescopic rod 4, which will not be described in detail here), the second telescopic rod 13 is fixedly connected to the adjacent first sliding block 3, the telescopic end of the second telescopic rod 13 is fixedly connected to the adjacent rotating cylinder 6, the fixed portion of the second telescopic rod 13 is fixedly connected to the fixed portion of the adjacent first telescopic rod 4 and is connected to a second flexible tube 14, the second flexible tube 14 is filled with hydraulic oil, and the hydraulic oil in the fixed portion of the first telescopic rod 4 enters the fixed portion of the adjacent second telescopic rod 13 under the extrusion force The telescopic end of the second telescopic rod 13 drives the adjacent rotating cylinder 6 to move synchronously, the telescopic end of the second telescopic rod 13 on the first sliding block 3 on the left side is moved upward by the hydraulic oil in the fixed part, and the telescopic end of the second telescopic rod 13 on the first sliding block 3 on the rear side is moved downward by the hydraulic oil in the fixed part, so that the distance between the adjacent first laser head 12 and the roller is kept consistent during rust removal, and a fixing component for fixing the roller of the shield machine is arranged in the support frame 1, and an end face rust removal component for rust removal of the end face of the roller of the shield machine is arranged in the support frame 1.

[0033] Combination Figure 1 , Figure 5 and Figure 6 As shown, the fixed assembly includes two first electric push rods 201 with mirror image distribution, and the two first electric push rods 201 with mirror image distribution are respectively fixed to the slider and the bottom of the support frame 1 through connecting pieces. The telescopic end of the first electric push rod 201 is rotatably connected to a rotating disk 202, and the rotating disk 202 is hinged with four connecting rods 203 in a circular array. The first electric push rod 201 drives the four connecting rods 203 to move up and down through the rotating disk 202, and the fixed platform 2 is rotatably connected to four fixing rods 204 in a circular array. The fixing rods 204 are connected to the fixing platform 2. 4 is an L-shaped rod, and the four connecting rods 203 of the circular array are respectively hinged with the adjacent fixing rods 204. The connecting rods 203 pull the adjacent fixing rods 204 to deflect along the fixing platform 2, and clamp and fix the bottom and top of the hob. The support frame 1 is provided with a rotating assembly for driving the adjacent fixing platform 2 to rotate. The upper and lower parts of the hob are alternately fixed by the four fixing rods 204 of the upper and lower groups of circular arrays, and then the first laser head 12 removes the rust on the upper and lower parts of the side of the hob in turn to ensure that the rust on the side of the hob is completely removed.

[0034] Combination Figure 5 and Figure 6As shown, the rotating assembly includes two servo motors 205 distributed in a mirror image, and the two servo motors 205 distributed in a mirror image are respectively arranged on the slider at the top of the supporting frame 1 and the bottom thereof through connecting parts. The output shaft of the servo motor 205 is fixedly connected with a rotating table 206. The rotating table 206 is in a truncated cone shape. The diameter of one end of the rotating table 206 close to the adjacent servo motor 205 is smaller than that of the other end. The rotating table 206 is fitted with the adjacent fixed table 2. The servo motor 205 drives the adjacent fixed table 2 to rotate through the adjacent rotating table 206. The fixed table 2 drives the hob to rotate through the four fixed rods 204 in a circular array thereon to perform rust removal.

[0035] Combination Figure 1 and Figure 7 As shown, the end face rust removal assembly includes a second sliding block 301, which is slidably connected to the right side of the support frame 1 through an electric slide rail, a telescopic push rod 302 is fixedly connected to the second sliding block 301, and the telescopic end of the telescopic push rod 302 is fixedly connected to a fixed frame 303, and the telescopic push rod 302 is used to drive the fixed frame 303 to move horizontally, and a second electric push rod 304 is fixedly connected to the outside of the fixed frame 303, and the telescopic end of the second electric push rod 304 is slidably connected to the fixed frame 303, and the fixed frame 303 is rotatably connected to two claws 305 distributed in a mirror image, and the second electric push rod 304 The telescopic end is hinged with two mirror-distributed pull rods 306, and the two mirror-distributed pull rods 306 are respectively hinged with adjacent claws 305. The telescopic end of the second electric push rod 304 drives the adjacent claws 305 to deflect along the fixed frame 303 through the two pull rods 306, so that the two mirror-distributed claws 305 clamp the middle part of the roller. The second sliding block 301 is fixedly connected with two second laser heads 307 distributed in upper and lower mirror images. The second laser head 307 is a scanning laser nozzle, which is used to remove rust from the end face of the roller. The second sliding block 301 is fixedly connected with a second dust suction head 308 distributed in upper and lower mirror images.

[0036] When it is necessary to remove rust from the roller cutter of the shield machine, the staff first places the roller cutter on the fixed platform 2 at the bottom of the support frame 1, and then turns on the first electric push rod 201 at the bottom. The telescopic end of the first electric push rod 201 drives the rotating disk 202 to move downward, and the rotating disk 202 drives the four connecting rods 203 in the circular array thereon to move downward synchronously, so that the connecting rod 203 drives the adjacent fixed rods 204 to rotate along the adjacent fixed platform 2, so that the four fixed rods 204 in the circular array clamp and fix the bottom of the roller cutter, and then the first electric push rod 201 at the bottom is closed.

[0037] When the roller is fixed, the electric slide rail on the support frame 1 drives the two first sliding blocks 3 distributed in a mirror image to slide, so that the first sliding blocks 3 on the left and rear sides slide to the top and the middle of the roller respectively and then stop sliding. At this time, the detection heads 5 on different first sliding blocks 3 are all in contact with the roller, and then the servo motor 205 at the bottom is turned on at this time, and the output shaft of the servo motor 205 drives the rotating table 206 thereon to rotate, and the rotation of the rotating table 206 drives the adjacent fixed table 2 to rotate, and the fixed table 2 drives the roller thereon to rotate synchronously, and then the two first laser heads 12 are turned on, and at the same time, the electric slide rail on the support frame 1 drives the first sliding block 3 located at the top of the roller to move downward and the first sliding block 3 located in the middle of the roller to move upward, and the two first sliding blocks 3 drive the first laser head 12 and the detection head 5 thereon to move synchronously, so that the first laser head 12 sprays laser to remove the rust on the outside of the roller, and at the same time, the two first dust suction heads 8 distributed in a mirror image are turned on to collect the smoke generated during laser rust removal. , until the first laser head 12 and the detection head 5 move to the blade of the hob, at this time, the radius of the hob gradually increases, the hob squeezes the two detection heads 5, and the detection head 5 is driven by the squeezing force to slide the telescopic end of the adjacent first telescopic rod 4 along its fixed part, and the telescopic end of the first telescopic rod 4 pushes the hydraulic oil in its fixed part into the adjacent first flexible tube 7, and the hydraulic oil flows along the first flexible tube 7 into the closed cavity formed by the adjacent rotating cylinder 6, the adjacent fixed plate 9, the adjacent rotating inner shaft 10 and the adjacent sliding plate 11, and then the hydraulic pressure in the closed cavity pushes the sliding plate 11 to rotate, and the sliding plate 11 drives the adjacent rotating inner shaft 10 to rotate synchronously, and the rotating inner shaft 10 drives the first laser head 12 thereon to rotate synchronously, so that the laser spraying direction of the first laser head 12 is perpendicular to the surface of the hob, so as to avoid that the spraying angle of the first laser head 12 is too fixed, resulting in excessive deviation between the rust surface of the blade and the spraying angle of the first laser head 12 when rust is removed at the blade, thereby enhancing the effect of rust removal on the rust surface of the blade.

[0038] When the detection head 5 is driven by the extrusion force to drive the telescopic end of the adjacent first telescopic rod 4 to slide along its fixed part, the hydraulic oil in the fixed part of the first telescopic rod 4 enters the fixed part of the adjacent second telescopic rod 13 along the second flexible tube 14. At this time, the hydraulic oil in the fixed part of the left second telescopic rod 13 pushes the telescopic end to drive the adjacent rotating cylinder 6 to move upward, and the hydraulic oil in the fixed part of the right second telescopic rod 13 pushes the telescopic end to drive the adjacent rotating cylinder 6 to move downward, so that the rotating cylinder 6 drives the first laser head 12 thereon to move synchronously. Since the rust removal angle of the first laser head 12 to the hob changes, the adjacent first sliding block 3 is moving step by step at this time, that is, the distance between the first laser head 12 and the hob changes, so that the second telescopic rod 13 drives the first laser head 12 to make up for the distance of the gradual movement of the first sliding block 3, ensuring that the distance between the first laser head 12 and the hob remains consistent when rotating, until both detection heads 5 move to the tip of the upper part of the hob, at which time the rust removal of the upper half of the side of the hob is completed.

[0039] When the rust removal of the upper half of the side of the roller is completed, the movement of the two first sliding blocks 3 is stopped, and the two first laser heads 12, the two first vacuum heads 8 and the servo motor 205 at the bottom are turned off at the same time. At this time, the fixed table 2 at the bottom stops rotating, and then the first electric push rod 201 at the bottom is turned on to reset the telescopic end of the first electric push rod 201 to the initial state, and the fixation of the roller is released. Then the electric slide rail on the support frame 1 drives the upper slider to move downward, and the slider drives the fixed table 2 on it to move downward and contact the upper end surface of the roller, and then the top of the roller is clamped and fixed by the first electric push rod 201 on the slider. When the top of the roller is fixed, the servo motor 205 on the slider is turned on, and the output shaft of the servo motor 205 drives the top fixed table 2 to rotate through the rotating table 206 on it, and the fixed table 2 drives the roller to rotate again, and then the support frame The frame 1 drives the first sliding blocks 3 on the left and rear sides to slide to the middle and bottom of the hob respectively through the electric slide rail. At this time, the hob releases the squeezing force on the two detection heads 5, and the detection heads 5 are still attached to the outside of the hob. The hydraulic oil in the closed cavity flows back to the fixed part of the first telescopic rod 4 along the adjacent first flexible tube 7. At the same time, the first laser head 12 is reset to the initial state, and then drives the middle first sliding block 3 to move downward, and the bottom first sliding block 3 to move upward. At the same time, the two first laser heads 12 and the two first vacuum heads 8 are turned on, and the above-mentioned rust removal steps are repeated. By alternately fixing the upper and lower parts of the hob, the rust on the upper and lower parts of the side of the hob is removed in turn to ensure that the rust on the side of the hob is completely removed, and this is done until the two detection heads 5 slide to the tip of the lower part of the hob, and the movement of the two first sliding blocks 3 is stopped. At this time, the rust removal work on the side of the hob is completed.

[0040] When the rust removal work on the side of the roller is completed, turn off the two first laser heads 12 and the two first vacuum heads 8, then turn off the servo motor 205 on the top, and at the same time turn on the first electric push rod 201 to release the fixation on the top of the roller, then the two first sliding blocks 3 and the slider move upward to the top of the support frame 1 and then stop moving, the electric slide rail on the support frame 1 drives the second sliding block 301 to slide downward to the middle of the roller, and then turn on the telescopic push rod 302, the telescopic end of the telescopic push rod 302 drives the fixed frame 303 to move, so that the fixed frame 303 drives the two claws 305 distributed in a mirror image thereon to move to both sides of the middle of the roller, and then turn on the second electric push rod 304, the telescopic end of the second electric push rod 304 extends out, and the telescopic end of the second electric push rod 304 is connected to the fixed frame 303 through the two mirror image distribution claws 305. The rod 306 pushes the adjacent claws 305 to rotate along the fixed frame 303 respectively, and the two mirror-distributed claws 305 rotate to contact the middle part of the roller and fix it, and then the second electric push rod 304 is closed, and the second sliding block 301 moves upward along the supporting frame 1, and drives the roller to move upward, so that the lower side of the roller is separated from the fixed platform 2 at the bottom, and then the telescopic push rod 302 is opened, and the telescopic end of the telescopic push rod 302 is reset to the initial position and then closed, and drives the roller thereon to move synchronously, and then the two second laser heads 307 and the two second dust heads 308 are turned on, so that the second laser head 307 performs laser rust removal on the end faces of the adjacent rollers, and the second dust head 308 extracts the smoke and dust during rust removal, and this is done until the rust removal of the two end faces of the roller is completed, at which time the rust removal of the roller is completed.

[0041] When the rust removal of the roller is completed, the two second laser heads 307 and the two second vacuum heads 308 are closed, and the telescopic push rod 302 is opened at the same time, so that the telescopic end of the telescopic push rod 302 drives the roller to return to its original position and then closes, and then the electric slide rail on the support frame 1 drives the second sliding block 301 to move downward, and the roller is placed on the fixed platform 2 at the bottom again, and then the second electric push rod 304 is opened, so that the telescopic end of the second electric push rod 304 is reset, and the adjacent claws 305 are pulled to reset through the two mirror-distributed pull rods 306, and the fixation of the roller is released, and then the telescopic push rod 302 is opened, so that the telescopic end drives the fixed frame 303 to reset to the initial state, and then the staff removes the roller that has been rust-removed, places the roller that needs to be rust-removed again, and repeats the above steps.

[0042] In this embodiment, the servo motor 205 is fixedly connected to the slider at the bottom or top of the support frame 1 through a connecting piece, but this is limited to embodiment one. In other subsequent embodiments, the servo motor 205 is slidingly connected to the slider at the bottom or top of the support frame 1 through a connecting piece. Please refer to the specific description in the subsequent embodiments.

[0043] Embodiment 2: Based on Embodiment 1, Figure 2 , Figure 5 and Figure 6 As shown, it also includes an adjustment component for changing the position of the two rotating tables 206 in mirror distribution, the adjustment component is arranged on the adjacent first sliding block 3, the adjustment component includes two third telescopic rods 401 in mirror distribution (the internal structure of the third telescopic rod 401 is the same as the first telescopic rod 4, which is not described in detail here), the two third telescopic rods 401 in mirror distribution are respectively fixed to the adjacent first sliding block 3, the telescopic ends of the two third telescopic rods 401 in mirror distribution are respectively fixed to the adjacent detection head 5, the slider at the top of the support frame 1 and the bottom thereof are fixedly connected with a fourth telescopic rod 402 through a connecting piece (the internal structure of the fourth telescopic rod 402 is the same as the first telescopic rod 4, which is not described in detail here), the telescopic end of the fourth telescopic rod 402 is connected to the adjacent servo motor 205 The fixed parts of the two mirror-distributed third telescopic rods 401 are fixedly connected to the fixed parts of the mirror-distributed fourth telescopic rod 402 and are connected by a third flexible tube 403. The third flexible tube 403 has sufficient margin to adapt to the position change between the third telescopic rod 401 and the two fourth telescopic rods 402. The third flexible tube 403 is filled with hydraulic oil. The slider at the top of the support frame 1 and the bottom thereof are slidably connected to the adjacent servo motor 205 through a connecting piece. The radius change of the roller is detected by the detection head 5, and the fitting position of the rotating table 206 and the adjacent fixed table 2 is changed, so as to reduce the transmission ratio of the rotating table 206 to the adjacent fixed table 2, so as to slow down the rotation speed of the fixed table 2, thereby driving the rotation speed of the roller thereon to slow down, thereby extending the rust removal time of the first laser head 12.

[0044] When the detection head 5 slides along the outside of the hob until the radius begins to increase, the detection head 5 drives the telescopic end of the adjacent third telescopic rod 401 to slide along its fixed part. At this time, the hydraulic oil in the fixed part of the third telescopic rod 401 enters the fixed parts of the two fourth telescopic rods 402 along the third flexible tube 403, and the hydraulic oil in the fixed part of the fourth telescopic rod 402 pushes its telescopic end to move. The telescopic end of the fourth telescopic rod 402 drives the adjacent servo motor 205 to move, and the servo motor 205 drives the rotating table 206 thereon to move synchronously. The rotating table 206 slides along the adjacent fixed table 2, changes the fitting position of the rotating table 206 and the adjacent fixed table 2, reduces the transmission ratio of the rotating table 206 to the fixed table 2, slows down the rotation speed of the fixed table 2, and then drives the rotation speed of the hob thereon to slow down, thereby extending the rust removal time of the first laser head 12, and avoiding that the area required for rust removal increases synchronously due to the increase in the radius of the hob, resulting in the first laser head 12 not completely removing rust from the rusted surface of the hob, and so on until the detection head 5 moves to the tip of the hob.

[0045] Then, when the rust removal position of the roller is changed again, the roller releases the squeeze on the detection head 5. At this time, the spring in the fixed part of the third telescopic rod 401 pushes the telescopic end to reset. At the same time, the hydraulic oil in the fixed part of the fourth telescopic rod 402 flows back to the two fixed parts of the third telescopic rods 401 along the adjacent third flexible tube 403. At the same time, the spring in the fixed part of the fourth telescopic rod 402 begins to reset and pushes the telescopic end of the fourth telescopic rod 402 to reset. The telescopic end of the fourth telescopic rod 402 drives the adjacent servo motor 205 to reset. When the rust removal of the side of the roller is needed again, repeat the above steps.

[0046] Embodiment 3: Based on Embodiment 2, Figure 7 , Fig. 9 and Fig.10 As shown, a limit assembly for preventing the shield machine cutter from sliding is also included. The limit assembly is arranged on the fixed frame 303. The limit assembly includes two support sleeves 501 with mirror distribution. The two support sleeves 501 with mirror distribution are spline-connected to the fixed frame 303. The two support sleeves 501 with mirror distribution are provided with a slide groove 502 inside. The slide groove 502 is a spiral groove, which is used to make the adjacent support sleeves 501 slide along the adjacent fixed frame 303. The fixed frame 303 is rotatably connected to the two first gears with mirror distribution. 503, the two mirror-distributed first gears 503 are fixedly connected with a clamping block 504, and the clamping block 504 is slidably connected to the adjacent slide groove 502. The rotation of the first gear 503 drives the adjacent clamping block 504 to rotate, so that the clamping block 504 slides along the adjacent slide groove 502, and pushes the adjacent support sleeves 501 to slide along the fixed frame 303, so that the two support sleeves 501 are respectively in contact with the two blades of the hob to form an internal support fixation, and the fixed frame 303 is provided with a driving component for driving the mirror-distributed first gear 503 to rotate.

[0047] like Figure 7-Figure 9 As shown, the driving assembly includes two second gears 505 distributed in a mirror image, and the two second gears 505 distributed in a mirror image are both rotatably connected to the adjacent fixed frame 303. The telescopic end of the second electric push rod 304 is fixedly connected with two racks 506 distributed in a mirror image, and the racks 506 distributed in a mirror image are respectively meshed with the adjacent second gears 505. The telescopic end of the second electric push rod 304 drives the adjacent second gear 505 to rotate through the movement of the two racks 506. The second gear 505 is meshed with the adjacent first gear 503. The rotation of the second gear 505 drives the adjacent first gear 503 to rotate. The first gear 503 drives the adjacent support sleeve 501 to move through the adjacent block 504 and the adjacent slide groove 502.

[0048] When the rust removal on the side of the hob is completed, the telescopic end of the telescopic push rod 302 drives the fixing frame 303 to extend to the middle of the hob, and the telescopic end of the second electric push rod 304 extends outward, so that the two mirror-distributed claws 305 clamp the middle of the hob. At this time, the telescopic end of the second electric push rod 304 drives the two mirror-distributed racks 506 to move synchronously. At this time, the rack 506 drives the adjacent second gear 505 to rotate synchronously, and the second gear 505 drives the adjacent first gear 503 to rotate. The first gear 503 The rotation drives the block 504 on it to rotate synchronously, and the block 504 rotates to slide along the adjacent slide groove 502, and pushes the adjacent support sleeve 501 to slide along the fixed frame 303 and contact the blade of the hob. The two support sleeves 501 distributed in a mirror image are supported between the two blades of the hob, thereby strengthening the clamping degree of the two claws 305 on the hob, avoiding sliding when the claws 305 clamp the hob and causing the hob to tilt, affecting the subsequent rust removal of the end face, and this continues until the rust removal of the end face is completed.

[0049] When the end face rust removal is completed, the roller is placed on the fixed platform 2 at the bottom. At this time, the telescopic end of the second electric push rod 304 contracts inward, driving the two claws 305 to separate from the roller. The telescopic end of the second electric push rod 304 synchronously drives the two mirror-distributed racks 506 to reset. The rack 506 drives the first gear 503 to reset through the adjacent second gear 505. The reset of the first gear 503 drives the adjacent support sleeve 501 to reset through the block 504 and the slide groove 502, so that it is separated from the roller. When the middle part of the roller needs to be fixed again, repeat the above steps.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
