Abstract
Description
Technical Field:
[0002] The utility model relates to a grinding device, in particular to a grinding device for defects on the aluminum plate surface. Background Art:
[0004] For aluminum plates used in new energy vehicles, especially aluminum plates for vehicle bodies, titanium / zirconium is generally coated on the surface of aluminum alloy materials to avoid surface oxidation, corrosion and damage. However, due to the coating on the surface, the defects of the aluminum material itself are covered. In further processes such as stamping, baking paint, and forming, the covered defects will cause further abnormalities, resulting in material waste. Seriously, it will affect the normal operation of the equipment and batch rework, and then lead to production suspension and line breakage, with serious consequences.
[0005] Common surface defects of aluminum plates for new energy vehicles include roll marks, color differences, indentations, etc. Their colors themselves are similar to those of aluminum alloy plates. Especially when the surface texture is the texture rolled under the electric spark process, these defects are more difficult to be found by the naked eye, and the surface defect detection cannot be directly carried out on them.
[0006] At present, in order to confirm the surface defect situation of aluminum plates before production or shipment, automobile OEMs or aluminum alloy strip processing plants and stamping plants all take continuous samples for surface grinding treatment before production or shipment. In order to improve the detection accuracy, it is necessary to take samples from the head, middle and tail of the batch materials for grinding and detection.
[0007] At present, when these aluminum plates are ground, the grinding dust is easily attached to the surface of the aluminum material, so it is necessary to use cloth to wipe it off and then conduct a careful inspection. The grinding and inspection time is long, and the defects cannot be found while grinding. Summary of the Invention:
[0009] In view of the above problems, the purpose of the utility model is to provide a grinding device for defects on the aluminum plate surface. The grinding device for defects on the aluminum plate surface is reasonably designed and is beneficial to improving the efficiency of grinding and inspection.
[0010] The grinding device for defects on the aluminum plate surface of the utility model is characterized in that: it includes a machine shell in the shape of a circular cover and a rotating shaft vertically passing through the machine shell. The rotating shaft is fixedly connected with a turntable located inside the machine shell. The lower surface of the turntable is detachably connected with a grinding sand screen. The lower surface of the periphery of the machine shell is connected with a circle of double-sided adhesive wool strips. When the grinding device is placed on the surface to be ground, the lower edge of the double-sided adhesive wool strips abuts against the surface to be ground. The machine shell is provided with a driving motor for driving the rotating shaft to rotate and an exhaust port for discharging dust. The exhaust port is connected with an air extraction pump through a pipeline; a lamp tube irradiating the surface to be ground is installed on the side of the machine shell.
[0011] Preferably, a plurality of convex portions are evenly distributed in the circumferential direction of the above-mentioned abrasive screen. After being bent by 90 degrees, the convex portions are locked with the screw holes on the circumferential surface of the turntable through bolts, so as to realize the relative fixation of the abrasive screen and the turntable.
[0012] Preferably, a coaxial first bevel gear is fixedly installed on the upper part of the above-mentioned rotating shaft, and a second bevel gear meshing with the first bevel gear is provided on the output shaft of the driving motor.
[0013] Preferably, an upper cover is provided on the upper part of the above-mentioned machine shell, the driving motor is fixed on the upper cover, and the exhaust port is also provided on the upper cover.
[0014] Preferably, a cylindrical ring-shaped frame surrounding the outer circumference of the upper cover is installed on the above-mentioned machine shell, and a plurality of counterweight blocks are provided in the cylindrical ring-shaped frame and above the upper cover.
[0015] Preferably, a drag bar for horizontally dragging the equipment is installed on the above-mentioned machine shell. The drag bar is U-shaped, and one end of the U-shaped drag bar is hinged to the first side of the upper cover, and the other end of the U-shaped drag bar is hinged to the second side of the upper cover.
[0016] The working method of the aluminum plate surface defect grinding equipment of the present invention is as follows. During work, the driving motor drives the rotating shaft and the turntable to rotate, so as to polish the surface of the aluminum plate through the abrasive screen. Since when the grinding equipment is placed on the surface to be ground, the lower peripheral edge of the back glue wool strip abuts against the surface to be ground, the dust generated during grinding will not overflow outside the machine shell, and through the action of the air extraction pump, the dust can be discharged (discharged into the filter cloth bag), avoiding the direct overflow of dust to the surface of the aluminum plate to be ground. In addition, through the lamp tube provided on the side of the machine shell and irradiating towards the surface to be ground, the defective surface of the aluminum plate can be more easily found, so that there is no need for the steps of wiping and inspecting after grinding, which is beneficial to improving the efficiency of grinding and inspection.

[0026] The following further describes the present utility model in conjunction with the accompanying drawings and specific implementation manners.
[0027] The abrasive equipment for aluminum plate surface defects of the present utility model includes a machine shell 1 in the shape of a circular cover and a rotating shaft 2 vertically passing through the machine shell. The machine shell 1 is in the shape of a circular cover, and the rotating shaft 2 is fixedly connected to a turntable 3 located inside the machine shell, so that the turntable 3 can be placed therein. A driving motor 6 for driving the rotating shaft to rotate is provided on the machine shell. When the driving motor 6 works, it drives the rotating shaft 2 and the turntable 3 to rotate.
[0028] The lower surface of the turntable 3 is detachably connected with an abrasive sanding mesh 4. Specifically, a plurality of convex parts 9 are evenly distributed in the circumferential direction on the abrasive sanding mesh 4. Both the abrasive sanding mesh 4 and the convex parts 9 thereon are in sheet shape. After the convex parts are bent by 90 degrees, they are locked with the screw holes on the circumferential surface of the turntable 3 through bolts or screws, thereby realizing the relative fixation of the abrasive sanding mesh and the turntable. The abrasive sanding mesh 4 is a consumable, so it needs to be frequently replaced by disassembling and assembling the screws.
[0029] A circle of adhesive-backed wool strips 5 is connected to the lower surface of the periphery of the machine shell 1. The adhesive-backed wool strips 5 are commercially available parts. Its specific structure is that fiber strips are fixed on the lower surface of an annular plastic sheet (the annular plastic sheet is locked on the lower surface of the periphery of the machine shell 1 through screws). When the abrasive equipment is placed on the surface to be ground, the lower edge of the adhesive-backed wool strip abuts against the surface to be ground (that is, the fiber strip contacts the surface to be ground), so that the machine shell 1 plays a role in wiping off some dust when moving.
[0030] An exhaust port 7 for discharging dust is provided on the machine shell. The exhaust port 7 is connected to an air extraction pump (not shown in the figure) through a pipeline. Through the action of the air extraction pump and the pipeline, the dust generated by grinding inside the machine shell can be adsorbed away to avoid dust adhering to the surface of the aluminum plate and affecting inspection.
[0031] A lamp tube 8 irradiating the surface to be ground is installed on the side of the machine shell. Through the lamp tube 8, the defects on the surface of the aluminum plate can be more easily discovered by the operator on-site during grinding, which is beneficial to improving the efficiency of grinding and inspecting at the same time, so that subsequent inspection is not required.
[0032] For the sake of reasonable design, an upper cover 12 is provided on the upper part of the above-mentioned casing 1, and the cover opening of the upper cover 12 is locked to the upper surface of the casing by bolts, wherein the drive motor 6 is fixed on the upper cover 12, and the exhaust port 7 is also provided on the upper cover; a coaxial first bevel gear 10 is fixedly installed on the upper part of the above-mentioned rotating shaft 2, and a second bevel gear 11 meshing with the first bevel gear is provided on the output shaft of the drive motor 6, that is, the first bevel gear 10 and the second bevel gear 11 are both provided in the space formed by the upper cover 12 and the upper surface of the casing 1, and the space formed by the upper cover 12 and the upper surface of the casing 1 to accommodate the first bevel gear 10 and the second bevel gear 11 can reduce the entry of dust and extend the service life of the first bevel gear 10 and the second bevel gear 11.
[0033] In order to ensure sufficient grinding force during the working process, a cylindrical annular frame 13 is installed on the casing 1 and is surrounded by the outer periphery of the upper cover. A plurality of counterweight blocks 14 are arranged inside the cylindrical annular frame and above the upper cover. The cylindrical annular frame 13 includes a plurality of vertically parallel vertical poles 16 and a plurality of connecting strips 17 fixedly connected between two adjacent vertical poles 16. The counterweight blocks 14 can be cast iron blocks. The lower part of the vertical pole 16 has a threaded section. The lower part of the vertical pole 16 passes through the through hole on the upper cover and is locked and fixed by a nut. The cylindrical annular frame 13 is used to limit the counterweight blocks 14 on the one hand, and can be used as a force application site for the operator to move the equipment horizontally on the other hand.
[0034] A towing rod 15 of a horizontal towing device is installed on the above-mentioned casing. The towing rod is U-shaped, one side end of the U-shaped towing rod is hinged to the first side of the upper cover, and the other side end of the U-shaped towing rod is hinged to the second side of the upper cover. The operator can press on both sides of the U-shape of the towing rod 15 with both hands to facilitate horizontal and vertical movement on the horizontal plane.
[0035] The working method of the aluminum plate surface defect grinding device of the utility model is as follows: when working, the driving motor drives the rotating shaft and the turntable to rotate, so as to grind the surface of the aluminum plate through the grinding sand net; because when the grinding device is placed on the surface to be ground, the lower peripheral edge of the adhesive-backed wool strip abuts against the surface to be ground, so that the dust generated by the grinding during the grinding process will not overflow outside the casing, and the dust can be discharged (discharged into the filter bag) through the action of the vacuum pump, so that the dust is avoided from directly overflowing to the surface to be ground of the aluminum plate; in addition, by means of the lamp tube arranged on the side of the casing to illuminate the surface to be ground, the defective surface of the aluminum plate can be more easily found, so that there is no need for wiping and re-inspection steps after grinding, which is conducive to improving the efficiency of grinding and inspection.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present invention or make equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
