Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a polishing structure for metal plate processing. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media.

[0003] However, in the prior art, when some existing metal plates need to be ground and polished on their surfaces, a sanding machine is generally used to complete the polishing process of the metal plates. When polishing the metal plates with a sanding machine, workers are generally required to manually press the metal plates onto the fast-moving sanding belt. Since a large amount of sparks are generated when the sanding belt is used to quickly grind and polish the metal plates, and the workers are close to the sparks at this time, the sparks can easily splash onto people's skin and cause burns. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: when a sanding belt machine is used to polish a metal plate, it is generally necessary for a worker to manually press the metal plate onto a fast-moving sanding belt. Since a large number of sparks are generated when the sanding belt is used to quickly polish the metal plate, and the worker is close to the sparks at this time, the sparks can easily splash onto people's skin and cause burns.

[0005] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0006] As a preferred embodiment, a rubber anti-slip pad is fixedly connected to one side surface of the clamping plate.

[0007] As a preferred embodiment, there are two screw rods, one end of each of the screw rods is fixedly connected to a gear, and a transmission belt is meshed and connected on the surface of the gear.

[0008] As a preferred embodiment, a limit plate is fixedly connected to the surface of the workbench near the location of the transmission belt.

[0009] Compared with the prior art, the advantages and positive effects of the present invention are:

[0010] The utility model drives the movement of the connecting plate and the clamping plate by the contraction of the electric telescopic rod, so that the clamping plate clamps and fixes the metal plate. With the help of the No. 2 motor and the lead screw, the mounting ring, the electric telescopic rod and the slider are driven to move downward along the track rod, thereby forcing the clamped metal plate to be pressed downward, so that its polishing surface fits closely with the sanding belt to ensure the polishing quality. In this way, the metal plate does not need to be manually pressed when polishing, and people can stay away from sparks generated by polishing, effectively avoiding burns.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1

[0018] like Figure 1-3 As shown, the utility model provides a technical solution: a polishing structure for metal sheet processing, including a workbench 1, a fixed support plate 2 is fixed on the top surface of the workbench 1, the fixed support plate 2 supports the sanding belt 4 located between the two transmission shafts 3, and the left and right ends of the fixed support plate 2 are rotatably connected with the transmission shaft 3. The sanding belt 4 is provided on the surface of the fixed support plate 2 and the transmission shaft 3, and the transmission shaft 3 continuously presses the two ends of the sanding belt 4 so that the transmission shaft 3 can stably drive the sanding belt 4 to move at the same time when rotating. When the sanding belt 4 moves, the surface of the metal sheet is close to the surface of the sanding belt 4, so that the metal sheet can be polished. A No. 1 motor 5 is fixed on the surface of the workbench 1, and the output shaft of the No. 1 motor 5 is fixedly connected to the transmission shaft 3. The No. 1 motor 5 plays the role of driving the transmission shaft 3 to move quickly. A track rod 6 is fixed on the surface of the workbench 1, and a slider 7 is slidably connected to the track rod 6. With the help of the slider 7 and the track rod 6, the electric extension is effectively improved. The stability of the telescopic rod 8 and the mounting ring 11 when they move up and down, the electric telescopic rod 8 is fixed on both sides of the slider 7, one end of the electric telescopic rod 8 is fixed with a connecting plate 9, and one end of the connecting plate 9 is fixed with a clamping plate 10, the contraction of the electric telescopic rod 8 drives the movement of the connecting plate 9 and the clamping plate 10, so that the clamping plate 10 clamps and fixes the metal sheet, the surface of the electric telescopic rod 8 is fixed with a mounting ring 11, and a screw rod 12 is rotated on the surface of the workbench 1, and a screw rod 12 is screwed between the screw rod 12 and the mounting ring 11. The workbench 1 is connected with a thread pattern, and a No. 2 motor 13 is fixed to one side surface of the workbench 1, and the output shaft of the No. 2 motor 13 passes through the workbench 1 and is fixed to the screw rod 12. The No. 2 motor 13 drives the screw rod 12 to rotate, thereby driving the mounting ring 11, the electric telescopic rod 8 and the slider 7 to move downward along the track rod 6, thereby forcing the clamped metal sheet to be pressed down, so that its polishing surface fits closely with the sanding belt 4 to ensure the polishing quality, so that the metal sheet does not need to be manually pressed during polishing, so that people can stay away from the sparks generated by polishing.

[0019] Example 2

[0020] like Figure 1-3As shown, a rubber anti-skid pad is fixedly connected to the surface of one side of the clamping plate 10. The setting of the rubber anti-skid pad can improve the friction of the extrusion surface of the clamping plate 10, thereby effectively improving the stability of the clamping plate 10 when clamping the metal plate. There are two screw rods 12, and one end of the two screw rods 12 is fixedly connected to a gear 14, and a transmission belt 15 is meshed and connected to the surface of the gear 14. With the help of the transmission of the gear 14 and the transmission belt 15, a single No. 2 motor 13 can drive multiple screw rods 12 to rotate together, without the need to repeatedly set the No. 2 motor 13, which effectively improves the utilization rate of the single No. 2 motor 13. A limiting plate 16 is fixedly connected to the surface of the workbench 1 near the position of the transmission belt 15. The limiting plate 16 plays a role in limiting the transmission belt 15, effectively improving the stability of the connection between the transmission belt 15 and the gear 14.
