Description

Technical Field

[0001] The utility model belongs to the technical field of steel belt processing equipment, and particularly relates to a steel belt oil grinding mechanism. Background Art

[0002] In the processing of steel belts, after the steel belts are produced, trimming treatment is required. Burrs will appear on the upper and lower surfaces of the left and right sides of the trimmed steel belts. If not polished, it will affect the quality of the steel belts, and it is not conducive to the packaging and use of subsequent processes. It is easy to cut hands during construction. Therefore, deburring the cut steel belts is one of the important processes in the production process and also one of the prerequisites for ensuring the quality of the steel belts. Due to the high hardness of the alloy, the existing deburring method is to manually polish by hand, which has low efficiency, is time-consuming and laborious, or use existing polishing equipment, which increases the construction cost and has limited application scope.

[0003] For this reason, a steel belt grinding wheel water mill for the production of nuclear industry butterfly spring alloys with the publication number of "CN215700393U" includes a main frame, a main motor is fixedly installed on the main frame, the output end of the main motor is drivingly connected to a grinding mechanism, the grinding mechanism is fixed to the main frame through a swing frame, a conveying mechanism is arranged below the grinding mechanism, and a guiding device is arranged on the conveying mechanism. The steel belt is transmitted through the conveying mechanism, and during the transmission process, the steel belt is polished by the grinding wheel. Before use, the swing arm bracket can adjust the height and angle according to the width of the steel belt and the size of the grinding wheel to meet the requirements of different polished products, and it is flexible and convenient to use, saving labor costs and time costs.

[0004] However, for the above-mentioned steel belt grinding wheel water mill for the production of nuclear industry butterfly spring alloys, although the main motor and the conveying motor are started, the main motor drives the grinding wheel to rotate, and the conveying motor drives the conveying mechanism to rotate, which is convenient and efficient for removing burrs on the steel belt. There are still the following obvious defects in the use process: the above-mentioned grinding wheel is rotationally fixed on the reduction gearbox rotating shaft, and since the other end of the grinding wheel is not fixed, the grinding wheel will shake during rotation and it is not conducive to the disassembly and assembly of the grinding wheel, so that the steel belt being water ground will have the problem that the local part of the steel belt is not water ground due to the shaking of the grinding wheel. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a steel belt oil grinding mechanism to solve the problems put forward in the above background art.

[0006] To achieve the above object, the utility model provides the following technical solution: A steel belt water grinding mechanism, including a frame groove, and a water grinding roller rotatably arranged in the middle of the end face of the frame groove. Assembly limit grooves for installing and disassembling the water grinding roller are provided on both sides of the end of the frame groove. A locking pressing plate for locking the bearing parts on the two ends of the rotating shaft of the water grinding roller is provided at the port of the assembly limit groove.

[0008] Preferably, rotating bearing parts are sleeved and fixed on the rotating shaft rods at both ends of the water grinding roller, and the rotating bearing parts are installed inside the bearing limit groove and locked and positioned by the locking pressing plate, realizing the positioning installation of the water grinding roller in the assembly limit groove at the end of the frame groove through the bearing parts, which is beneficial for later disassembly.

[0009] Preferably, a servo motor is installed on one side outside the frame groove through a provided bottom plate. A gear A is installed on the rotating shaft of the servo motor, and the gear A is meshed and driven to connect with a gear B installed on the rotating shaft rod at one end of the water grinding roller. Through the meshing drive of the gear A and the gear B up and down, it is convenient for the disassembly and installation of the water grinding roller.

[0010] Preferably, a cylinder A is symmetrically arranged horizontally inside the water collecting groove. The top end of the cylinder A is fixed with a lifting frame in a U-shaped structure. The two ends of the lifting frame penetrate into the frame groove and are rotatably connected with the shaft rods at both ends of the supporting conveying roller, which is beneficial for lifting the conveyed steel belt to contact the surface of the water grinding roller for water grinding and polishing operations.

[0011] Preferably, cylinders B are symmetrically arranged on both sides of the feeding and discharging ports provided at the front and rear of the frame groove. One end of the cylinder B is fixed on one side of the positioning plate part. A water spraying pipe is horizontally arranged inside the frame groove at the rear end of the water grinding roller. Water spraying pipe heads inclined towards one side bottom surface of the water grinding roller are evenly arranged on the bottom surface of the water spraying pipe, so that when the water grinding roller polishes the steel belt, water is sprayed on the steel belt and the water grinding roller for heat dissipation and temperature reduction.

[0012] Compared with the prior art, the technical effects and advantages of the present utility model are as follows: For this steel strip water grinding mechanism, the water grinding roller is positioned and installed in the assembly limit grooves provided on both side walls of the frame groove through the rotating bearing parts on the two end rotating shaft rods. And the rotating bearing parts are positioned in the bearing limit grooves, and the top end of the outer ring of the rotating bearing parts is locked and positioned by the locking pressing plate, making the water grinding roller more stable and firm during the rotation meshed by the servo motor. At the same time, when the rotating bearing parts of the water grinding roller are worn, only by removing the locking pressing plate from the end of the frame groove, the water grinding roller together with the rotating bearing parts can be removed from the assembly positioning groove. At the same time, it can keep the water grinding roller horizontal to perform water grinding operation on the surface of the conveyed steel strip, thereby facilitating the replacement of the water grinding roller and related rotating bearing parts, and further improving the convenience of disassembly and assembly of the water grinding roller.

[0013] Through the cylinder B and positioning plate parts provided on both sides of the front and rear end inlet and outlet ports of the frame groove, during the water grinding of steel strips with different widths, the positioning width between the positioning plate parts can be adjusted by the cylinder B, and at the same time, the input end and output end of the steel strip can be positioned simultaneously, ensuring that the steel strip always remains in the center position during the rotation and water grinding process by the water grinding roller, and thus the phenomenon of steel strip deviation will not occur. Furthermore, the water grinding operation on steel strips with different widths can be realized. Through the combined use of the cylinder A, lifting frame, and supporting conveying roller, the water grinding operation on different thicknesses can be carried out, enabling steel strips with different thicknesses to be water ground by the water grinding roller, further improving the application range and practicability of the water grinding mechanism.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , the present utility model provides a technical solution: a steel strip oil grinding mechanism, including a frame groove 1 and a water grinding roller 2 rotatably arranged in the middle of the end face of the frame groove 1. The rotating shell of the water grinding roller 2 performs water grinding on steel strips of different widths during transportation. Water grinding can remove surface roughness, oxide layer, rust and other impurities on the steel strip. Assembly limit grooves 3 for installing and disassembling the water grinding roller 2 are provided on both sides of the end of the frame groove 1. The water grinding roller 2 can be installed inside the frame groove 1 by means of assembly positioning, which is conducive to the disassembly and assembly of the water grinding roller 2 in the later stage. A locking pressing plate 4 for locking the bearing parts on the two ends of the rotating shaft of the water grinding roller 2 is provided at the port of the assembly limit groove 3. After the water grinding roller 2 is horizontally positioned in the assembly limit groove 3, the locking pressing plate 4 is used to lock and press down to lock the two ends of the water grinding roller 2. Strip-shaped grinding parts 5 for rolling and grinding the surface of the steel strip are uniformly arranged on the surface of the water grinding roller 2 in a circle. The strip-shaped grinding parts 5 used in the water grinding of the steel strip are usually a kind of hard granular material, such as alumina, silicon carbide, etc. These abrasive grains rotate at high speed under the impact and lubrication of water, and use their hardness and sharp edges to grind the metal surface. The frictional force and pressure generated by the action of the abrasive grains cause the uneven parts on the surface of the workpiece to be ground off, gradually achieving the required surface finish and accuracy.

[0022] Rotating shaft rods 6 for driving the rotation of the water grinding roller 2 are installed at both ends of the water grinding roller 2 through screws. After the water grinding roller 2 is positioned and installed on the rotating shaft rods 6, the water grinding roller 2 can be fixed by moving it downward. A support conveying roller 7 that movably penetrates into the inside of the frame groove 1 and performs pneumatic lifting is provided at the bottom of the frame groove 1 to realize the output and input during the water grinding of the steel strip. A water collecting tank 8 for collecting the sewage generated by the water film is provided at the bottom of the frame groove 1, which can enable the sprayed water to flow downward into the water collecting tank 8 for collection. External equipment can be used to treat the sewage and then reuse it. Positioning plate parts 9 for pneumatically positioning and conveying the conveyed steel strip are provided on both sides of the inlet and outlet grooves opened on the front and rear end surfaces of the frame groove 1, which can play a role in positioning the input and output steel strips and ensure the stability during the water grinding process of the steel strip.

[0023] An assembly limit groove 3 is provided at one end of the frame groove 1, and a bearing limit groove 10 is opened inside the assembly limit groove 3. The outer ring of the rotating bearing part 12 is limited and assembled inside the bearing limit groove 10 for positioning. There is no need to fix the water grinding roller 2 by screws. A positioning pressure groove 11 for positioning and pressing the top of the outer ring of the bearing part is provided on one side of the locking pressure plate 4 corresponding to the assembly limit groove 3, ensuring the stability of the rotating bearing part 12 during the rotation of the water grinding roller 2, and facilitating the later disassembly, installation and replacement of the rotating bearing part 12. Rotating bearing parts 12 are sleeved and fixed on the rotating shaft rods 6 at both ends of the water grinding roller 2, and the rotating bearing parts 12 are installed inside the bearing limit groove 10 and locked and positioned by the locking pressure plate 4, realizing the downward pressure positioning of the top of the outer ring of the rotating bearing part 12. A servo motor 13 is installed on one side outside the frame groove 1 through a provided bottom plate. A gear A14 is installed on the rotating shaft of the servo motor 13, and the gear A14 is meshed and drivingly connected to a gear B15 installed on the rotating shaft rod 6 at one end of the water grinding roller 2, realizing the transmission of the water grinding roller 2 and facilitating the disassembly and assembly of the water grinding roller 2.

[0024] Inside the water collecting groove 8, a cylinder A16 is symmetrically arranged horizontally. The top of the cylinder A16 is fixed with a lifting frame 17 in a U-shaped structure, which can adjust the vertical height of the distance between the support conveying roller 7 and the bottom end of the water grinding roller 2 inside the frame groove 1, enabling the water grinding of steel strips with different thicknesses. And the sewage can flow to the water collecting groove 8 from the position where the lifting frame 17 penetrates the frame groove 1. The two ends of the lifting frame 17 penetrate into the frame groove 1 and are rotatably connected to the shaft rods at both ends of the support conveying roller 7, capable of supporting and conveying the steel strip. On both sides of the inlet and outlet openings provided at the front and back of the frame groove 1, cylinders B18 are symmetrically arranged. One end of the cylinder B18 is fixed on one side of the positioning plate member 9, realizing the positioning of the input end and the output end of the steel strip. Horizontally inside the frame groove 1 and at the rear end of the water grinding roller 2, a water spraying pipe 19 is provided. The bottom surface of the water spraying pipe 19 is evenly provided with water spraying pipe heads 20 inclined towards one side bottom surface of the water grinding roller 2, realizing the function of cooling the surface of the steel strip and the surface of the water grinding roller 2.

[0025] Specifically, during use, first, the servo motor 13, cylinder A 16, and cylinder B 18 are connected to an external control unit and controlled to enable the steel belt to penetrate from the front end of the frame groove 1 and pass through the support conveying roller 7 so that the steel belt adheres to the surface of the water grinding roller 2. Subsequently, the servo motor 13 is started to drive the gear A 14 to rotate, and the meshing of the gear A 14 drives the gear B 15 to rotate. The rotation of the gear B 15 drives the water grinding roller 2 to rotate inside the frame groove 1 through the rotating bearing member 12, and the rotation of the water grinding roller 2 drives the strip-shaped grinding member 5 to rotate to perform water grinding surface treatment on the surface of the steel belt. At the same time, the input end of the steel belt uses the cylinder B 18 to push the positioning plate member 9 for positioning to ensure the stability of the input of the steel belt at the input end. The water-ground steel belt is output from the output port at the rear end of the frame groove 1, and the cylinder B 18 is used to push the positioning plate member 9 to position the positions on both sides of the steel belt, which can ensure that the steel belt always maintains a horizontal and centered state during the water grinding process. During the water grinding process, an external water pump transports water into the water spray pipe 19 and sprays the water obliquely onto the surfaces of the steel belt and the water grinding roller 2 through a number of obliquely arranged water spray nozzles 20 for water cooling. The water grinding roller 2 is positioned and installed in the assembly limit grooves 3 provided on both side walls of the frame groove 1 by the rotating bearing members 12 on the two end rotating shaft rods 6, and the rotating bearing members 12 are positioned in the bearing limit grooves 10. Moreover, the top end of the outer ring of the rotating bearing member 12 is locked and positioned by the locking pressure plate 4, making the rotation of the water grinding roller 2 more stable and firm during the meshing drive by the servo motor 13. At the same time, when the rotating bearing member 12 of the water grinding roller 2 wears, the water grinding roller 2 together with the rotating bearing member 12 can be removed from the assembly limit groove 3 only by removing the locking pressure plate 4 from the end of the frame groove 1. At the same time, the water grinding roller 2 can be kept horizontal to perform water grinding operations on the surface of the conveyed steel belt, thereby facilitating the replacement of the water grinding roller 2 and the related rotating bearing members 12.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
