Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, specifically a metal sheet burr removal and polishing device. Background Technology

[0002] As basic components in industries such as electronics, automobiles, and hardware, metal sheets have burrs on their edges that directly affect the assembly accuracy and safety of products. If the burrs exceed 0.05mm, they may cause poor contact of electronic components or jamming of automotive parts. Therefore, burr removal is a key post-processing step in the processing of metal sheets.

[0003] Based on the above, the inventors have discovered the following problems: Existing burr grinding devices mostly adopt a "single grinding wheel / single sanding belt + fixed station" design, which can only grind one edge (single side) of the metal sheet at a time. To complete the full edge grinding of a metal sheet, the station needs to be adjusted or the workpiece needs to be flipped multiple times, which directly lengthens the processing cycle, which is problematic for large-scale production.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a metal sheet burr grinding device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a metal sheet burr grinding device to solve the problem mentioned in the background art that the existing burr grinding devices mostly adopt the design of "single grinding wheel / single sanding belt + fixed station", which can only grind one edge (single side) of the metal sheet at a time.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A metal sheet deburring device includes a main body and a grinding mechanism. The main body includes a base with an adjustment groove at the center of its upper end. Industrial vacuum cleaners are fixedly mounted on both sides of the base. The grinding mechanism includes a pair of fixed frames, the bottom ends of which are slidably connected to the two ends of the adjustment groove. A pair of first rollers are rotatably connected to the opposing surfaces of the pair of fixed frames. A first abrasive belt is wound between each pair of first rollers. A movable frame is movably inserted into the top of each fixed frame. Second rollers are rotatably connected to both sides of the bottom end of the movable frame. A second abrasive belt is wound between each pair of second rollers. A dust suction hood is inserted into the opposing back surfaces of the pair of fixed frames. One end of the dust suction hood is connected to the input end of the industrial vacuum cleaner through a metal corrugated pipe.

[0008] Furthermore, each of the fixed frames is equipped with a first electric telescopic rod inserted into its upper end, and the output end of the first electric telescopic rod is fixedly connected to the top of the movable frame.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the first electric telescopic rod on the fixed frame can drive the moving frame to move up and down, adjust the distance between the second grinding belt and the metal sheet, adapt to the grinding needs of metal sheets of different thicknesses, and at the same time control the grinding pressure to avoid excessive pressure damaging the sheet or insufficient pressure causing incomplete grinding.

[0010] Furthermore, a transmission box is fixedly installed on one side of each of the movable frames. A pair of synchronous pulleys are rotatably connected inside the transmission box, and a synchronous belt is wound between each pair of synchronous pulleys. A first servo motor is fixedly installed on the upper side of one side of the transmission box. The output end of the first servo motor is drivenly connected to one of the synchronous pulleys in each pair. The central axis of the other synchronous pulley in each pair is connected to one end of a second roller. A second servo motor is fixedly installed on the outer side of each of the fixed frames, and the output end of the second servo motor is drivenly connected to one of the first rollers.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the first servo motor drives the second roller and the second grinding belt to rotate through the synchronous pulley and the synchronous belt, and the second servo motor drives the first roller and the first grinding belt to rotate, ensuring the stable operation of the sanding belt.

[0012] Furthermore, a dual-axis motor is fixedly installed at the center of the bottom of the adjustment groove. Both output ends of the dual-axis motor are fitted with screws. The threads of the pair of screws are opposite, and the opposite ends of the pair of screws are rotatably connected to the two ends of the adjustment groove, respectively.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the dual-axis motor in the adjustment groove drives a pair of screws with opposite threads to rotate, which can drive the sliders on both sides and the fixed frame to move synchronously in opposite directions, quickly adjust the spacing of the pair of fixed frames, adapt to the grinding needs of metal sheets of different widths, and is convenient to operate and has high adjustment accuracy.

[0014] Furthermore, each screw is threaded with a slider, the top of a pair of sliders is fixedly connected to the bottom of a pair of fixed frames, a first telescopic dust cover is fixedly installed between each pair of sliders, a second telescopic dust cover is fixedly installed on the opposite ends of each pair of sliders, and the opposite ends of a pair of second telescopic dust covers are respectively connected to the two ends of the adjustment groove.

[0015] The beneficial effects of adopting the above-mentioned further solution are that the slider on the screw drives the fixed frame to move stably, and the first telescopic dust cover and the second telescopic dust cover can cover the opening of the adjustment groove to prevent grinding dust and debris from entering the interior of the adjustment groove, thereby avoiding affecting the smooth sliding of the screw and slider and reducing the frequency of equipment maintenance.

[0016] Furthermore, support frames are fixedly installed on both sides of the upper end of the base. The bottom of each support frame is provided with a first conveying roller, and a pair of second electric telescopic rods are inserted into the top of each support frame. The bottom of each pair of second electric telescopic rods is provided with a second conveying roller.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the support frames on both sides of the base provide an installation foundation for the conveying structure. The first conveying roller and the second conveying roller cooperate to clamp the metal sheet from above and below, ensuring that the sheet is conveyed smoothly during the grinding process, avoiding the sheet from shifting and causing the grinding position deviation, and improving the grinding accuracy.

[0018] Furthermore, each of the support frames is fixedly mounted with a connecting frame at its upper end, and each of the connecting frames is slidably inserted with a mounting frame at its lower end. Each of the mounting frames is rotatably connected with a conveyor wheel at its lower end.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the mounting frame on the connecting frame drives the conveyor wheel to move up and down, and the height of the conveyor wheel can be adjusted according to the thickness of the metal sheet. The conveyor wheel assists in pushing the sheet to move, and works with the first conveyor roller and the second conveyor roller to realize continuous conveying of the sheet, thereby improving processing efficiency.

[0020] Furthermore, a third electric telescopic rod is inserted at the center of the top of each connecting frame. The output end of the third electric telescopic rod is connected to the top of the mounting frame. A third servo motor is fixedly installed at one end of each mounting frame. The output end of the third servo motor is connected to the conveyor wheel drive.

[0021] The beneficial effects of adopting the above-mentioned further solution are that the third electric telescopic rod drives the mounting frame and the conveyor wheel to lift and lower, ensuring that the contact force between the conveyor wheel and the sheet is appropriate; the third servo motor drives the conveyor wheel to rotate, which can control the sheet conveying speed, so that the conveying speed matches the grinding speed, avoiding the sheet being conveyed too fast, which would lead to incomplete grinding, or too slow, which would cause local over-grinding.

At the same time, the first electric telescopic rod 202 is started to drive the moving frame 205 to descend, so that the second grinding belt 209 fits against the upper end of the sheet, and works with the first grinding belts 213 on both sides to grind the burrs on the top, bottom and sides of the sheet from multiple directions. During the grinding process, the industrial vacuum cleaner 102 is started, and the dust and debris generated by grinding are absorbed through the dust hood 204 and the metal corrugated pipe. The ground sheet is output from the other side of the device. Then, all motors and the vacuum cleaner can be turned off.
