Description

Technical Field

[0001] The present invention relates to the technical field of cold-drawn steel polishing, and specifically to a polishing mechanism for the surface layer of a cold-drawn steel body. Background Art

[0002] The surface polishing of cold-drawn steel is to polish the surface of cold-drawn steel plates by mechanical methods to improve their surface quality and smoothness. It is usually used for products with high appearance quality requirements. This process can not only remove the defects and impurities on the steel plate surface, but also improve its surface finish, increase the corrosion resistance, and at the same time enhance its aesthetics. The surface polishing of cold-drawn steel plates is a highly technical process that requires precise control of each link to ensure that the polishing effect meets the quality requirements of the product.

[0003] The patent with the publication number CN113523977A discloses a steel plate polishing device adaptable to multiple sizes. The steel plate is conveyed to the polishing conveying assembly by the feeding conveying assembly. The polishing conveying assembly polishes the surface of the steel plate and conveys the steel plate to the discharging conveying assembly. The discharging conveying assembly discharges and conveys the steel plate. The polishing conveying assembly includes a conveyor belt mechanism. The bottom end of the conveyor belt mechanism is connected to an installation table, and an installation frame is connected to the installation table. The installation frame is erected above the conveyor belt mechanism. A polishing mechanism for polishing the steel plate on the conveyor belt mechanism is connected to the installation frame, which can flexibly adjust the distance relative to the conveyor belt mechanism, thereby controlling the position of the polishing mechanism relative to the polishing surface of the steel plate, flexibly adapting to steel plates of different size specifications, ensuring the smooth progress of the polishing operation of steel plates of different size specifications, and improving the polishing efficiency and quality of the steel plate. However, this patent still has the problem that debris from grinding is likely to remain on the polishing wheel, which gradually increases the loss of the polishing disc and affects the polishing effect. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a polishing mechanism for the surface layer of a cold-drawn steel body, which solves the problems raised in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A polishing mechanism for the surface layer of a cold-drawn steel body, including an outer frame, a viewing door panel is fixedly connected to the side surface of the outer frame, a top plate is fixedly connected to the top surface of the outer frame, transverse movement rod ends are fixedly connected to both sides of the top end of the inner table frame, a support end is slidably connected to the side surface of each transverse movement rod end, a polishing mechanism is arranged between the two support ends, a flap collection mechanism is arranged at the bottom end inside the outer frame, and a positioning and assisting mechanism is arranged below the polishing mechanism;

[0006] The polishing mechanism includes a driving motor. The bottom end of the output shaft of the driving motor is fixedly connected to a vertical screw rod. A screw block is threadedly connected to the outer surface of the vertical screw rod. A moving frame is arranged between the two screw blocks. The bottom end of the supporting end is fixedly connected to a driving block. A polishing assembly is installed above the moving frame. The top end of the supporting end is fixedly connected to a top frame.

[0007] Preferably, a fuel tank is fixedly connected to the middle position of the top frame. A lubricating oil cavity is arranged on the right side of the fuel tank. A fixing piece is fixedly connected to the middle position of the inner wall of the lubricating oil cavity. An oil inlet pipe is fixedly connected to the bottom side of the lubricating oil cavity. A piston is slidably connected to the right side of the fixing piece. A piston rod is fixedly connected to the side of the piston away from the fixing piece. An air inlet port is fixedly connected to the top side of the right end of the lubricating oil cavity. An air delivery pipe is fixedly connected to the bottom side of the right end of the lubricating oil cavity. A one-way lobe is fixedly connected to the middle position of the fixing piece. An oil delivery pipe is fixedly connected to the left end of the lubricating oil cavity. The end of the oil delivery pipe away from the lubricating oil cavity is fixedly connected to a lubricating oil ring. A swing handle is arranged above the lubricating oil ring.

[0008] Preferably, the polishing assembly includes a pressure relief frame. The pressure relief frame is slidably connected above the moving frame. The top end of the pressure relief frame is fixedly connected to a cavity plate. Three polishing wheels are installed on the side of the pressure relief frame. Scraping pieces are fixedly connected to both sides of the cavity plate. A fixing frame block is fixedly connected to the front side of the moving frame. A fixing plate block is fixedly connected to the side of the pressure relief frame. A buffer spring is arranged between the fixing plate block and the fixing frame block, and both ends of the buffer spring are fixedly connected to the fixing plate block and the fixing frame block respectively. The inside of the cavity plate is a hollow structure, and small holes are opened in the cavity plate corresponding to the positions directly below the polishing wheels.

[0009] Preferably, the vertical screw rod is rotatably connected to the bottom end of the supporting end. The screw block is slidably connected to the inner wall of the supporting end. The screw block is fixedly connected to the moving frame. The lubricating oil cavity is fixedly connected to the top frame. The end of the oil inlet pipe away from the lubricating oil cavity is fixedly connected to the fuel tank. One-way lobes are fixedly connected to the inner walls of the air inlet port, the air delivery pipe and the oil inlet pipe.

[0010] Preferably, the swing handle is fixedly connected to the top end of the vertical screw rod, the lubricating ring is fixedly connected to the support end, a compression spring is arranged between the fixing piece and the piston, and both ends of the compression spring are fixedly connected to the fixing piece and the piston respectively. The steel is fed under the polishing wheel through the conveyor belt at the front end of the outer frame. At this time, the external control terminal controls the operation of the driving motor of the top frame, so that the driving motor drives the vertical screw rod connected to the output shaft to rotate. The rotation of the vertical screw rod drives the screw block to move downward, and the movement of the screw block drives the connected moving frame to move downward. Thus, the polishing wheel on the moving frame operates driven by the external motor and approaches the steel plate below for polishing. When the polishing wheel contacts the steel, the moving frame continues to move downward, causing the polishing wheel to move upward against the force and drive the connected fixed plate to stretch the buffer spring upward. At the same time, the polishing wheel drives the connected pressure relief frame to slide upward along the moving frame, so as to make the polishing wheel adapt to fit the surface of the steel, avoid excessive pressure on the surface of the steel, and improve the polishing use range of steel with different thicknesses. The movement of the driving block adopts the existing technology and will not be elaborated here. While the driving motor drives the vertical screw rod to rotate through the output shaft, the swing handle connected to the vertical screw rod rotates to push the end of the plug rod to be stressed, so that the stressed plug rod slides along the lubricating cavity and drives the piston to move. At this time, the piston squeezes the connected compression spring to be compressed, and allows the outside air to pass through the one-way lobe in the intake port unidirectionally, so that the air fills into the lubricating cavity adjacent to the piston. When the plug rod is no longer stressed as the swing handle rotates, at this time, the compression spring releases its elastic force to push the piston to reset and unidirectionally output the air inside the lubricating cavity adjacent to the piston through the one-way lobe in the air delivery pipe to the inside of the cavity plate, and the cavity plate discharges through the small holes on the bottom surface to blow off the residual debris on the polishing wheel, preventing the residual debris on the polishing wheel from affecting the effect of the next polishing. In addition, when the piston resets away from the fixing piece under the action of the compression spring, the air pressure decreases due to the increase in the space between the fixing piece and the piston, and the liquid in the fuel tank will enter unidirectionally between the fixing piece and the piston through the connected oil inlet pipe. When the swing handle rotates again to push the plug rod to be stressed, the piston squeezes the liquid to flow into the side of the fixing piece away from the piston through the one-way lobe in the middle of the fixing piece and accumulates until the accumulated liquid level is higher than the height of the connection between the oil delivery pipe and the lubricating cavity, and part of the liquid accumulated in the lubricating cavity will enter the lubricating ring through the oil delivery pipe and lubricate and maintain the vertical screw rod as the vertical screw rod in the lubricating ring rotates, so as to reduce wear and structural damage through automatic lubrication and maintenance, avoid the influence of structural loss on polishing accuracy, and improve the service life of worn parts.

[0011] Preferably, the flap collecting mechanism includes a lower pressing plate, a resilient block is slidably connected below the lower pressing plate, a transverse groove rod is arranged below the resilient block, vertical sliders are fixedly connected to both the front and rear ends of the transverse groove rod, a vertical sliding rod is slidably connected to the middle position of the vertical sliders, an inclined push rod is hingedly connected to the side of the vertical slider, a transverse groove block is hingedly connected to the end of the inclined push rod away from the vertical slider, a lifting rod is hingedly connected to the top end of the transverse groove block, a filter screen convex plate is hingedly connected to the end of the lifting rod away from the transverse groove block, a telescopic lifting rod is fixedly connected to the bottom end of the filter screen convex plate, a collecting groove is fixedly connected to the outer surface of the bottom end of the telescopic lifting rod, a middle rod is fixedly connected to the middle position of the top end of the inner platform frame, and a flipping table plate is arranged above the filter screen convex plate.

[0012] A resistance spring is arranged between the resilient block and the lower pressing plate, and both ends of the resistance spring are fixedly connected to the resilient block and the lower pressing plate respectively. The vertical sliding rod is fixedly connected to the inner platform frame, and the vertical slider is slidably connected to the inner platform frame. A vertical spring is arranged outside the vertical sliding rod, and both ends of the vertical spring are fixedly connected to the vertical slider and the inner platform frame respectively. The bottom end of the telescopic lifting rod is fixedly connected to the inner platform frame. The flipping table plate is hingedly connected to the outer frame. The filter screen convex plate has a protruding structure at its upward extension. After polishing is completed, the screw block drives the moving frame to move the polishing assembly away from the steel. When the screw block drives the connected lower pressing plate to move upward, the resistance spring connected to the lower pressing plate releases its elastic force to reset the resilient block. At this time, the transverse groove rod is no longer pressed by the resilient block, so that the transverse groove rod moves upward along the vertical sliding rod under the action of the vertical spring at the bottom side of the connected vertical slider. When the vertical sliding rod moves upward, it will drive the connected inclined push rod to pull the transverse groove block to move horizontally along the connection of the inner platform frame. After the movement, the transverse groove block pulls the lifting rod, so that the end of the lifting rod away from the transverse groove block pulls the filter screen convex plate to contract the connected telescopic lifting rod, so that the filter screen convex plate descends and approaches the collecting groove. When the flipping table plate is no longer supported by the protruding part of the filter screen convex plate structure, the flipping table plate will flip and tilt around the connection of the inner platform frame as a node to fit the protruding part of the filter screen convex plate structure, so that the debris after polishing by the civil air defense slides down along the inclined flipping table plate into the filter screen convex plate, and the polishing debris and rust particles generated during the polishing process are separated and collected through the filter screen convex plate by filtration, avoiding the subsequent cleaning after polishing is completed and preventing the polishing debris and rust particles from affecting the flatness of the subsequent accessory placement.

[0013] Preferably, the positioning and assisting mechanism includes a clamping plate, the clamping plate is slidably connected to the inner platform frame, two upper hinge rods are hingedly connected to both the front and rear sides of the moving frame, a retractable connecting rod is slidably connected to the end of each upper hinge rod away from the moving frame, a long connecting rod is hingedly connected to the end of the retractable connecting rod away from the upper hinge rod, a hinge block is fixedly connected to the side of the long connecting rod close to the retractable connecting rod, and a wheel is rotatably connected to the side of the hinge block.

[0014] Preferably, a pull-down spring is provided at the bottom end of the buckle plate, and both ends of the pull-down spring are fixedly connected to the buckle plate and the bottom surface of the transverse groove rod respectively. A spring piece is provided inside the retractable connecting rod, and both ends of the spring piece are fixedly connected to the retractable connecting rod and the upper hinge rod respectively. The end of the long connecting rod away from the retractable connecting rod is hinged to the support end. When the screw block moves downward and approaches to drive the lower pressing plate to move downward, the lower pressing plate pushes the elastic block through the resistance spring to press the transverse groove rod. Since the elastic force of the resistance spring is greater than the elastic force of the vertical spring, at this time, after being pressed by the elastic block, the transverse groove rod will move downward and squeeze the pull-down spring to pull the buckle plate downward, so that the buckle plate moves vertically downward along the inner bench connection, pressing the edge of the auxiliary part plate to prevent the auxiliary part plate from shifting during the laser polishing process and affecting the accuracy of polishing. In addition, when the moving frame moves downward to drive the connected upper hinge rod, the upper hinge rod pushes the spring piece in the retractable connecting rod to push the retractable connecting rod, so that the retractable connecting rod pushes the long connecting rod to turn downward around the connection of the support end as a node. The turned long connecting rod drives the connected hinge block and the wheel to approach the lower plate, so that the wheel presses the auxiliary part plate. Since the polished plate will undergo slight deformation and bending due to thermal expansion and contraction, by pressing the polished part, it is avoided that the plate bulges during polishing and affects the polishing effect and quality.

[0015] The present invention provides a polishing mechanism for the surface layer of a cold-drawn steel body. It has the following beneficial effects:

[0016] In the present invention, through the driving motor, vertical screw, screw block, moving frame, driving block, polishing wheel, polishing assembly, top frame, oil tank, lubricating oil cavity, oil inlet pipe, fixing piece, piston, piston rod, air inlet port, air delivery pipe, one-way lobe, oil delivery pipe, swing handle, lubricating oil ring, the polishing wheel drives the connected pressure relief frame to slide upward along the moving frame, adapting and fitting to the surface of the steel to avoid excessive pressure on the surface of the steel and improving the polishing application range for steels of different thicknesses. At the same time, the air inside the oil cavity is unidirectionally output to the inside of the cavity plate through the one-way lobe in the air delivery pipe, and the cavity plate discharges through the small holes on the bottom surface to blow off the residual debris on the polishing wheel, preventing the residual debris on the polishing wheel from affecting the next polishing effect. In addition, only part of the liquid accumulated in the lubricating oil cavity will enter the lubricating oil ring through the oil delivery pipe and lubricate and maintain the vertical screw as the vertical screw rotates in the lubricating oil ring, thereby reducing wear and structural damage through automatic lubrication and maintenance, avoiding the influence of structural loss on polishing accuracy, and prolonging the service life of worn parts;

[0017] In the present invention, by providing a lower pressing plate, elastic blocks, horizontal groove rods, vertical sliders, vertical sliding rods, inclined push rods, horizontal groove blocks, lifting rods, filter screen convex plates, lifting and telescoping rods, flipping table plates, middle rods, and collection grooves, the debris after polishing for civil air defense slides along the inclined flipping table plate into the filter screen convex plate, and the filter screen convex plate separates and collects the polishing debris and rust particles generated during the polishing process through filtration, avoiding the subsequent cleaning after polishing and preventing the polishing debris and rust particles from affecting the flatness of the subsequent accessory placement.

[0018] In the present invention, by providing a buckle plate, long connecting rods, hinged blocks, wheels, retractable connecting rods, and upper hinge rods, the flipped long connecting rod drives the connected hinged blocks and wheels to approach the lower plate, so that the wheels press on the accessory plate. Since the polished plate is slightly deformed and bent due to the influence of thermal expansion and contraction, by pressing on the polished part, it is avoided that the plate bulges during polishing and affects the polishing effect and quality.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] At the inner bottom end of the outer frame 1, a flap collecting mechanism 6 is provided. Below the polishing mechanism 5, a positioning auxiliary mechanism 7 is provided. At the bottom end of the support end 4, a driving block 55 is fixedly connected. At the bottom side of the lubricating oil chamber 510, an oil inlet pipe 511 is fixedly connected. On the right side of the fixed piece 512, a piston 513 is slidably connected. On the side of the piston 513 away from the fixed piece 512, a piston rod 514 is fixedly connected. At the top side of the right end of the lubricating oil chamber 510, an air inlet port 515 is fixedly connected. At the bottom side of the right end of the lubricating oil chamber 510, an air delivery pipe 516 is fixedly connected. Above the lubricating oil ring 520, a swing handle 519 is provided. The polishing assembly 57 includes a pressure relief frame 571. The pressure relief frame 571 is slidably connected above the moving frame 54. At the top end of the pressure relief frame 571, a cavity plate 572 is fixedly connected. On the side of the pressure relief frame 571, three polishing wheels 56 are installed. On both sides of the cavity plate 572, scraping blades 573 are fixedly connected. At the front side of the moving frame 54, a fixed frame block 575 is fixedly connected. On the side of the pressure relief frame 571, a fixed plate block 574 is fixedly connected. Between the fixed plate block 574 and the fixed frame block 575, a buffer spring is provided, and both ends of the buffer spring are fixedly connected to the fixed plate block 574 and the fixed frame block 575 respectively. The vertical screw rod 52 is rotatably connected to the bottom end of the support end 4. The screw block 53 is slidably connected to the inner wall of the support end 4. The screw block 53 is fixedly connected to the moving frame 54. The lubricating oil chamber 510 is fixedly connected to the top frame 58. The end of the oil inlet pipe 511 away from the lubricating oil chamber 510 is fixedly connected to the fuel tank 59. On the inner walls of the air inlet port 515, the air delivery pipe 516 and the oil inlet pipe 511, one-way valve flaps 517 are fixedly connected. The swing handle 519 is fixedly connected to the top end of the vertical screw rod 52. The lubricating oil ring 520 is fixedly connected to the support end 4. Between the fixed piece 512 and the piston 513, a compression spring is provided, and both ends of the compression spring are fixedly connected to the fixed piece 512 and the piston 513 respectively. The steel is fed into the lower part of the polishing wheel 56 through the front conveyor belt of the outer frame 1. At this time, the external control terminal controls the operation of the driving motor 51 of the top frame 58, so that the driving motor 51 drives the vertical screw rod 52 connected to the output shaft to rotate. The rotation of the vertical screw rod 52 drives the screw block 53 to move downward. Through the movement of the screw block 53, the connected moving frame 54 moves downward, so that the polishing wheel 56 on the moving frame 54 operates under the drive of the external motor and approaches the lower steel plate for polishing. When the polishing wheel 56 contacts the steel, the moving frame 54 continues to move downward, so that the polishing wheel 56 is forced to move upward reversely, driving the connected fixed plate block 574 to stretch the buffer spring upward. At the same time, the polishing wheel 56 drives the connected pressure relief frame 571 to slide upward along the moving frame 54, so as to adapt the polishing wheel 56 to fit the surface of the steel, avoid excessive pressure on the surface of the steel, and improve the polishing use range of steel with different thicknesses. The movement of the driving block 55 all adopts existing technologies and will not be elaborated too much. When the driving motor 51 drives the vertical screw rod 52 to rotate through the output shaft, the swing handle 519 connected to the vertical screw rod 52 rotates to push the end of the piston rod 514 to receive force, so that the piston rod 514 after receiving force slides along the lubricating oil chamber 510 and pushes the piston 513 to move. At this time, the piston 513 squeezes the connected compression spring and is compressed.And allow outside air to pass unidirectionally through the one-way lobe 517 in the intake port 515, so that the air fills into the lubricating oil chamber 510 adjacent to the piston 513. When the piston rod 514 is no longer under pressure as the swing handle 519 rotates, at this time, the compression spring releases elastic force to push the piston 513 to reset and unidirectionally output the air inside the lubricating oil chamber 510 adjacent to the piston 513 through the one-way lobe 517 in the air delivery pipe 516 to the inside of the cavity plate 572, and allow the cavity plate 572 to discharge through the bottom small holes to blow off the residual debris on the polishing wheel 56, preventing the residual debris on the polishing wheel 56 from affecting the effect of the next polishing. In addition, when the piston 513 resets away from the fixed piece 512 under the action of the compression spring, the air pressure decreases due to the increase in the space between the fixed piece 512 and the piston 513, which will allow the liquid in the fuel tank 59 to enter unidirectionally through the connected oil inlet pipe 511 between the fixed piece 512 and the piston 513. When the swing handle 519 rotates again to push the piston rod 514 to be stressed, the piston 513 squeezes the liquid to flow through the one-way lobe 517 in the middle of the fixed piece 512 to the side of the fixed piece 512 away from the piston 513 and accumulates until the accumulated liquid level is higher than the height of the connection between the oil delivery pipe 518 and the lubricating oil chamber 510, and a part of the liquid accumulated in the lubricating oil chamber 510 will enter the lubricating ring 520 through the oil delivery pipe 518 and lubricate and maintain the vertical screw rod 52 as the vertical screw rod 52 rotates in the lubricating ring 520, so as to reduce wear and structural damage through automatic lubrication and maintenance, avoid structural loss affecting polishing accuracy, and extend the service life of worn parts.

[0033] The flap collecting mechanism 6 includes a lower pressing plate 61, with an elastic block 62 slidably connected below the lower pressing plate 61. A transverse groove rod 63 is arranged below the elastic block 62. Vertical sliders 64 are fixedly connected to both the front and rear ends of the transverse groove rod 63. A vertical slide rod 65 is slidably connected to the middle position of the vertical slider 64. An inclined push rod 66 is hinged to the side of the vertical slider 64. One end of the inclined push rod 66 away from the vertical slider 64 is hinged to a transverse groove block 67. A lifting rod 68 is hinged to the top end of the transverse groove block 67. One end of the lifting rod 68 away from the transverse groove block 67 is hinged to a filter screen convex plate 69. A lifting and telescoping rod 610 is fixedly connected to the bottom end of the filter screen convex plate 69. A collecting groove 613 is fixedly connected to the outer surface of the bottom end of the lifting and telescoping rod 610. A middle rod 612 is fixedly connected to the middle position of the top end of the inner table frame 8. A flipping table plate 611 is arranged above the filter screen convex plate 69. A resistance spring is arranged between the elastic block 62 and the lower pressing plate 61, and both ends of the resistance spring are fixedly connected to the elastic block 62 and the lower pressing plate 61 respectively. The vertical slide rod 65 is fixedly connected to the inner table frame 8, and the vertical slider 64 is slidably connected to the inner table frame 8. A vertical spring is arranged outside the vertical slide rod 65, and both ends of the vertical spring are fixedly connected to the vertical slider 64 and the inner table frame 8 respectively. The bottom end of the lifting and telescoping rod 610 is fixedly connected to the inner table frame 8. The flipping table plate 611 is hinged to the outer frame 1. The filter screen convex plate 69 has a convex structure at the upward extension. After polishing is completed, the screw block 53 drives the moving frame 54 to move the polishing assembly 57 away from the steel. When the screw block 53 drives the connected lower pressing plate 61 to move upward, the resistance spring connected to the lower pressing plate 61 releases elastic force to reset the elastic block 62. At this time, the transverse groove rod 63 is no longer pressed by the elastic block 62, so that the transverse groove rod 63 moves upward along the vertical slide rod 65 under the action of the vertical spring at the bottom side of the connected vertical slider 64. When the vertical slide rod 65 moves upward, it will drive the connected inclined push rod 66 to pull the transverse groove block 67 to move horizontally along the connection with the inner table frame 8. After moving, the transverse groove block 67 pulls the lifting rod 68, so that one end of the lifting rod 68 away from the transverse groove block 67 pulls the filter screen convex plate 69 to contract the connected lifting and telescoping rod 610, so that the filter screen convex plate 69 descends and approaches the collecting groove 613. When the flipping table plate 611 is no longer supported by the convex structure of the filter screen convex plate 69, the flipping table plate 611 will rotate and tilt around the connection with the inner table frame 8 to fit the convex structure of the filter screen convex plate 69. Thus, the debris after civil air defense polishing slides into the filter screen convex plate 69 along the inclined flipping table plate 611, and the polishing debris and rust particles generated during the polishing process are separated and collected through filtration by the filter screen convex plate 69, avoiding the subsequent cleaning after polishing and preventing the polishing debris and rust particles from affecting the flatness of the subsequent accessory placement.

[0034] The positioning and assisting mechanism 7 includes a clamping plate 71 which is slidably connected to the inner bench 8. Two upper hinge rods 76 are hingedly connected to both the front and rear sides of the moving frame 54. One end of each upper hinge rod 76 away from the moving frame 54 is slidably connected to a retractable connecting rod 75. One end of the retractable connecting rod 75 away from the upper hinge rod 76 is hingedly connected to a long connecting rod 72. A hinge block 73 is fixedly connected to the side of the long connecting rod 72 near the retractable connecting rod 75. A wheel 74 is rotatably connected to the side of the hinge block 73. A downward pulling spring is arranged at the bottom end of the clamping plate 71, and the two ends of the downward pulling spring are respectively fixedly connected to the clamping plate 71 and the bottom surface of the transverse groove rod 63. A spring piece is arranged inside the retractable connecting rod 75, and the two ends of the spring piece are respectively fixedly connected to the retractable connecting rod 75 and the upper hinge rod 76. The end of the long connecting rod 72 away from the retractable connecting rod 75 is hingedly connected to the supporting end 4. When the screw block 53 moves downward and approaches to drive the lower pressing plate 61 to move downward, the lower pressing plate 61 pushes the elastic block 62 through the resistance spring to apply pressure to the transverse groove rod 63. Since the elastic force of the resistance spring is greater than that of the vertical spring, at this time, the transverse groove rod 63 will move downward after being pressed by the elastic block 62 and squeeze the downward pulling spring to pull the clamping plate 71 downward, so that the clamping plate 71 moves vertically downward along the connection of the inner bench 8, presses the edge of the auxiliary part plate, and avoids the displacement of the auxiliary part plate during the laser polishing process, which affects the accuracy of polishing. In addition, when the moving frame 54 moves downward to drive the connected upper hinge rods 76, the upper hinge rods 76 push the spring piece in the retractable connecting rod 75 to push the retractable connecting rod 75, so that the retractable connecting rod 75 pushes the long connecting rod 72 to turn downward around the connection of the supporting end 4 as a node. The turned long connecting rod 72 drives the connected hinge block 73 and the wheel 74 to approach the lower plate, so that the wheel 74 applies pressure to the auxiliary part plate. Since the polished plate will have slight deformation and bending due to the influence of thermal expansion and contraction, by applying pressure to the polished part, it is avoided that the plate bulges during polishing deformation, which affects the polishing effect and quality.

[0035] Working principle: The steel is fed under the polishing wheel 56 through the front conveyor belt of the outer frame 1. At this time, the external control terminal controls the operation of the driving motor 51 of the top frame 58, so that the driving motor 51 drives the vertical screw rod 52 connected to the output shaft to rotate. The rotation of the vertical screw rod 52 drives the screw block 53 to move downward. The movement of the screw block 53 drives the connected moving frame 54 to move downward, so that the polishing wheel 56 on the moving frame 54 operates driven by the external motor and approaches the steel plate below for polishing. When the polishing wheel 56 touches the steel, the moving frame 54 continues to move downward, causing the polishing wheel 56 to move upward reversely under force and drive the connected fixed plate 574 to stretch the buffer spring upward. At the same time, the polishing wheel 56 drives the connected pressure relief frame 571 to slide upward along the moving frame 54, using the polishing wheel 56 to adapt to and fit the surface of the steel, avoiding excessive pressure on the surface of the steel, and improving the polishing use range for steels of different thicknesses. The movement of the driving block 55 adopts existing technologies and will not be elaborated here. When the driving motor 51 drives the vertical screw rod 52 to rotate through the output shaft, the rotation of the swing handle 519 connected to the vertical screw rod 52 pushes the end of the plug rod 514 to be stressed. The stressed plug rod 514 slides along the lubricating oil cavity 510 and pushes the piston 513 to move. At this time, the piston 513 squeezes the connected compression spring to be stressed, and allows the outside air to pass unidirectionally through the one-way flap 517 in the air intake port 515, filling the air into the lubricating oil cavity 510 adjacent to the piston 513. When the plug rod 514 is no longer stressed as the swing handle 519 rotates, the compression spring releases its elastic force to push the piston 513 to reset and unidirectionally output the air inside the lubricating oil cavity 510 adjacent to the piston 513 through the one-way flap 517 in the air delivery pipe 516 into the cavity plate 572, and the cavity plate 572 discharges through the bottom holes to blow off the residual debris on the polishing wheel 56, preventing the residual debris on the polishing wheel 56 from affecting the polishing effect next time. In addition, when the piston 513 resets away from the fixed piece 512 under the action of the compression spring, the air pressure decreases due to the increase in the space between the fixed piece 512 and the piston 513, causing the liquid in the fuel tank 59 to enter unidirectionally between the fixed piece 512 and the piston 513 through the connected oil inlet pipe 511. When the swing handle 519 rotates again to push the plug rod 514 to be stressed, the piston 513 squeezes the liquid to flow through the one-way flap 517 in the middle of the fixed piece 512 into the side of the fixed piece 512 away from the piston 513 and accumulates until the accumulated liquid level is higher than the height of the connection between the oil delivery pipe 518 and the lubricating oil cavity 510, and part of the liquid accumulated in the lubricating oil cavity 510 will enter the lubricating oil ring 520 through the oil delivery pipe 518 and lubricate and maintain the vertical screw rod 52 as the vertical screw rod 52 rotates in the lubricating oil ring 520, thereby reducing wear and structural damage through automatic lubrication and maintenance, avoiding the influence of structural loss on polishing accuracy, and improving the service life of worn parts;

[0036] After polishing is completed, the screw block 53 drives the moving frame 54 to move the polishing assembly 57 away from the steel. When the screw block 53 drives the connected lower pressing plate 61 to move upward, the resistance spring connected to the lower pressing plate 61 releases elastic force to reset the elastic block 62. At this time, the horizontal groove rod 63 is no longer pressed by the elastic block 62, and the horizontal groove rod 63 moves upward along the vertical slide rod 65 under the action of the vertical spring at the bottom side of the connected vertical slider 64. When the vertical slide rod 65 moves upward, it will drive the connected inclined push rod 66 to pull the horizontal groove block 67 to move horizontally along the connection with the inner table frame 8. The moved horizontal groove block 67 pulls the lifting rod 68, and the end of the lifting rod 68 away from the horizontal groove block 67 pulls the filter screen convex plate 69 to contract the connected lifting and telescopic rod 610, so that the filter screen convex plate 69 descends and approaches the collection tank 613. When the flipping table plate 611 is no longer supported by the convex part of the filter screen convex plate 69 structure, the flipping table plate 611 will flip and tilt around the connection with the inner table frame 8 as a node to fit the convex part of the filter screen convex plate 69 structure. Thus, the debris after civil air defense polishing slides into the filter screen convex plate 69 along the inclined flipping table plate 611, and the polishing debris and rust particles generated during the polishing process are separated and collected through filtration by the filter screen convex plate 69, avoiding the subsequent cleaning after polishing is completed and preventing the polishing debris and rust particles from affecting the flatness of the subsequent accessory placement;

[0037] When the screw block 53 moves downward and approaches to drive the lower pressing plate 61 to move downward, the lower pressing plate 61 pushes the elastic block 62 through the resistance spring to press the horizontal groove rod 63. Since the elastic force of the resistance spring is greater than the elastic force of the vertical spring, at this time, the horizontal groove rod 63 will move downward after being pressed by the elastic block 62 and squeeze the lower pull spring to pull the buckle plate 71 downward, so that the buckle plate 71 moves vertically downward along the connection of the inner table frame 8, and presses the edge of the accessory plate through the downward movement of the buckle plate 71, avoiding the displacement of the accessory plate during the laser polishing process and affecting the accuracy of polishing. In addition, when the moving frame 54 moves downward, it drives the connected upper hinge rod 76, and the upper hinge rod 76 pushes the spring piece in the contraction connecting rod 75 to push the contraction connecting rod 75, so that the contraction connecting rod 75 pushes the long connecting rod 72 to flip downward around the connection of the supporting end 4 as a node. The flipped long connecting rod 72 drives the connected hinge block 73 and the wheel 74 to approach the lower plate, and the wheel 74 presses the accessory plate. Due to the influence of thermal expansion and contraction, the polished plate will have a slight deformation and bending. By pressing the polished part, it is avoided that the plate bulges during polishing and affects the polishing effect and quality.
