Description

Technical Field

[0001] This utility model relates to the field of grinding devices, specifically a rapid grinding tool. Background Technology

[0002] Grinding, as a surface treatment method, generally refers to a processing method that uses a rough object (such as sandpaper containing high-hardness particles) to change the physical properties of a material surface through friction. Grinding is usually required during the processing and production of product workpieces, mainly to make the surface layer of the product workpiece smooth, delicate, or neat. With the progress and development of science, the application of sheet metal is becoming more and more widespread, and the processing and production of sheet metal parts has become a very important part of industrial production. Boxes made of sheet metal have the characteristics of light weight, high strength, and low cost, and are widely used in daily life.

[0003] After the existing sheet metal boxes are processed, burrs will appear on the outer surface of the box. This mainly occurs in the shearing die and blanking die. Burrs will be produced when the gap between the cutting edges is large or small. Usually, the surface is polished manually. This polishing work is inefficient, time-consuming and labor-intensive, and it is impossible to polish the surface of the sheet metal box smoothly, resulting in inconsistent production quality of sheet metal boxes.

[0004] Furthermore, during the grinding process of sheet metal boxes, a lot of debris is generated. Existing grinding tools do not have the function of collecting waste, resulting in a lot of debris on the workbench of workers during grinding, affecting the working environment and making it difficult to clean. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a quick polishing tool to solve the technical problems of time-consuming and laborious polishing and inconvenient debris collection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid grinding tool, comprising a base, a worktable on the base, a grinding table on the worktable, a rotating assembly inside the worktable, the rotating assembly including a turntable, a connecting rod, and a rotating component, a first rotating shaft installed inside the worktable, a turntable mounted on the first rotating shaft, a connecting rod mounted on the turntable, a connecting component mounted at the end of the connecting rod, a second rotating shaft installed inside the worktable, a rotating component mounted on the second rotating shaft, a groove on the rotating component matching the connecting component, the end of the second rotating shaft connected to the grinding table, a third rotating shaft installed inside the worktable, a gear mounted on the third rotating shaft, a movable component slidably installed inside the worktable, multiple sets of teeth meshing with the gear on both sides of the movable component, a base plate fixed to the end of the movable component, a grinding disc mounted on the base plate, and a brush slidably installed on the worktable.

[0007] By adopting the above technical solution, the connecting part is inserted into the groove of the rotating part by controlling the rotation of the turntable, thereby driving the rotating part to rotate. The rotating part rotates 90° for every turn of the turntable, so that the grinding table rotates 90° regularly. This allows all four sides of the sheet metal box placed on the grinding table to be ground, eliminating the need for manual grinding and rotation by workers, saving time and labor. Moreover, each side is ground more evenly, reducing production errors. By setting up moving parts and gears, the rotation of the gears can drive the moving parts to reciprocate, so that when the sheet metal box rotates, the grinding disc is away from the sheet metal box, giving the sheet metal box enough space to rotate and preventing the grinding disc from hitting the edge of the sheet metal box and causing wear. By setting up a brush, the worker can use the brush to clean and tidy up the worktable after the grinding work is completed.

[0008] The present invention is further configured such that the end of the first rotating shaft is connected to the output end of the motor, a first pulley is mounted on the first rotating shaft, a second pulley is mounted on the third rotating shaft, and the first pulley and the second pulley are connected by belt drive.

[0009] By adopting the above technical solution, the first shaft is driven to rotate by a motor, which in turn causes the first pulley to rotate, thereby driving the second pulley to rotate. This causes the gear coaxially connected to the second pulley to rotate, saving a lot of energy and meeting the environmental protection requirements of modern production.

[0010] The present invention is further configured such that the grooves are arranged in four groups, and the grooves are U-shaped.

[0011] By adopting the above technical solution, the grooves are set into four groups so that when the turntable rotates one revolution, it drives the rotating part to rotate 90°.

[0012] The present invention is further configured such that the gear is an incomplete gear, and the number of teeth of the gear is four sets.

[0013] By adopting the above technical solution, the gear can drive the moving parts to reciprocate in a regular manner when rotating, so that when the sheet metal box rotates, the grinding disc moves away from the sheet metal box and the grinding disc can only grind away the burrs on the surface of the sheet metal box, preventing over-grinding and damage to the sheet metal box.

[0014] The present invention is further configured such that slide rails are provided on both sides of the workbench, sliders matching the slide rails are provided on both sides of the brush, and handles are provided on the side of the brush.

[0015] By adopting the above technical solution, the brush can slide back and forth on the workbench, and the worker can control the movement of the brush with the handle to clean up the debris on the workbench.

[0016] The present invention is further configured such that a collection box is slidably mounted on the base, and a rolling platform is provided at the end of the workbench, the rolling platform being inclined at an angle of 45°.

[0017] By adopting the above technical solution, the debris cleaned by the brush can fall into the collection box along the rolling platform for unified collection, and then the collection box can be removed for processing, making it convenient for workers to centrally remove the debris.

[0018] The present invention is further configured such that the grinding table is provided with four sets of fixing blocks, and the fixing blocks are configured in an L shape.

[0019] By adopting the above technical solution, the fixing block can fix the four corners of the sheet metal box during grinding, preventing the sheet metal box from moving during grinding and ensuring that each surface is ground evenly.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model, by setting up a rotating component, a turntable, and a connecting component, controls the rotation of the turntable so that the connecting component enters the groove of the rotating component, thereby driving the rotating component to rotate. When the turntable rotates once, the rotating component will rotate 90°, so that the four sides of the sheet metal box placed on the grinding table can be ground. There is no need for workers to grind and rotate manually, saving time and effort, and each side is ground more evenly, reducing production errors.

[0022] 2. This utility model, by setting gears and moving parts, enables the moving parts to reciprocate when the gears rotate, so that when the sheet metal box rotates, the grinding disc moves away from the sheet metal box, giving the sheet metal box enough space to rotate, preventing the grinding disc from touching the edge of the sheet metal box and causing wear, and allowing the grinding disc to only grind away the burrs on the surface of the sheet metal box, preventing over-grinding and damage to the sheet metal box.

[0023] 3. By setting a first pulley and a second pulley, this utility model eliminates the need for multiple motors to simultaneously drive the first and third shafts, saving a significant amount of energy and meeting the environmental protection requirements of modern production.

[0024] 4. This utility model, by setting up a brush and a collection box, allows workers to directly slide the brush to clean the debris on the workbench into the collection box after grinding, and then take out the collection box for processing, which is convenient and quick.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] A rapid polishing tool, as shown in Figures 1-5, includes a base 1, a worktable 2 on the base 1, and a polishing table 3 on the worktable 2. The worktable 2 has a rotating assembly inside, which includes a turntable 61, a connecting rod 611, and a rotating component 71. A first rotating shaft 6 is installed inside the worktable 2, with the turntable 61 mounted on the first rotating shaft 6. The connecting rod 611 is mounted on the turntable 61, and a connector 612 is installed at the end of the connecting rod 611. A second rotating shaft 7 is installed inside the worktable 2, and a polishing table 3 is mounted on the second rotating shaft 7. The device is equipped with a rotating component 71, which has a groove 72 that matches the connecting component 612. The end of the second rotating shaft 7 is connected to the grinding table 3. When the first rotating shaft 6 rotates, it drives the turntable 61 and the connecting rod 611 to rotate, thereby causing the connecting component 612 to rotate into the groove 72. This causes the rotating component 71 to rotate 90° and then leave the groove 72. One rotation of the first rotating shaft 6 drives the turntable 61 to rotate 90°, thereby causing the grinding table 3 to rotate. The four sides of the sheet metal box placed on the grinding table 3... All sides can be polished without manual polishing and rotation by workers, saving time and labor. Each side is polished more evenly, reducing production errors. A third rotating shaft 8 is installed inside the worktable 2, and a gear 81 is mounted on the third rotating shaft 8. A moving part 9 is slidably installed inside the worktable 2. Multiple sets of teeth 91 meshing with the gear 81 are provided on both sides of the moving part 9. A base plate 4 is fixed to the end of the moving part 9, and a polishing disc 5 is mounted on the base plate 4. Rotation of the third rotating shaft 8 drives the gear 81 to rotate, thus enabling the moving part 5 to polish. The reciprocating motion of component 9 causes the base plate 4 and the grinding disc 5 to reciprocate. When the sheet metal box rotates, the grinding disc 5 moves away from the sheet metal box, giving the sheet metal box enough space to rotate, preventing the grinding disc 5 from touching the edge of the sheet metal box and causing wear. It also allows the grinding disc 5 to only grind and remove burrs on the surface of the sheet metal box, preventing over-grinding and damage to the sheet metal box. A brush 10 is slidably installed on the workbench 2. After the grinding work is completed, the worker can use the brush 10 to clean and tidy the workbench.

[0034] Please see Figure 2 and Figure 3 In the above embodiment, the end of the first rotating shaft 6 is connected to the output end of the motor. A first pulley 62 is installed on the first rotating shaft 6, and a second pulley 82 is installed on the third rotating shaft 8. The first pulley 62 and the second pulley 82 are connected by belt drive. The first rotating shaft 6 is driven to rotate by the motor, thereby causing the first pulley 62 to rotate, which in turn drives the second pulley 82 to rotate. As a result, the gear 81, which is coaxially connected to the second pulley 82, rotates, saving a lot of energy and meeting the environmental protection requirements of modern production.

[0035] Please see Figure 2 and Figure 3In the above embodiment, the grooves 72 are set in four groups and are U-shaped, so that when the turntable 61 rotates one revolution, it drives the rotating component 71 to rotate 90°.

[0036] Please see Figure 2 , Figure 3 and Figure 4 In the above embodiment, gear 81 is an incomplete gear with four sets of teeth. When gear 81 rotates, it can regularly drive the moving part 9 to reciprocate, so that when the sheet metal box rotates, the grinding disc 5 moves away from the sheet metal box and allows the grinding disc 5 to only grind away the burrs on the surface of the sheet metal box, preventing over-grinding and damage to the sheet metal box.

[0037] Please see Figure 1 and Figure 5 In the above embodiment, slide rails 21 are provided on both sides of the workbench 2, and sliders 101 matching the slide rails 21 are provided on both sides of the brush 10. A handle 102 is provided on the side of the brush 10. The brush 10 can slide back and forth on the workbench 2. The worker can control the movement of the brush 10 through the handle 102 to clean up the debris on the workbench 2, which is convenient and quick.

[0038] Please see Figure 1 In the above embodiment, a collection box 11 is slidably installed on the base 1, and a rolling platform 22 is provided at the end of the workbench 2. The rolling platform 22 is inclined at an angle of 45°. The debris cleaned by the brush 10 can fall into the collection box 11 along the rolling platform 22 for unified collection. Then the collection box 11 is taken out for processing, which makes it convenient for workers to centrally remove the debris.

[0039] Please see Figure 1 In the above embodiment, the grinding table 3 is provided with four sets of fixing blocks 31, and the fixing blocks 31 are set in L shape. The fixing blocks 31 can fix the four corners of the sheet metal box during grinding to prevent the sheet metal box from moving during grinding and ensure that each surface is ground evenly.

[0040] The working principle of this utility model is as follows: When grinding the sheet metal box, the sheet metal box is first placed on the grinding table 3, and the four corners of the sheet metal box are fixed by the fixing block 31. Then, the motor is turned on, so that the first rotating shaft 6 rotates, which drives the turntable 61 and the connecting rod 611 to rotate, thereby causing the connecting piece 612 to rotate into the groove 72, and the rotating piece 71 to rotate 90° and leave the groove 72. The first rotating shaft 6 rotates one revolution, which drives the turntable 61 to rotate 90°, thereby causing the grinding table 3 to rotate. When the first rotating shaft 6 rotates, the first pulley 62 rotates, which drives the second pulley 82 to rotate, thereby causing the gear 81 coaxially connected to the second pulley 82 to rotate, thereby causing the moving piece 9 to reciprocate, which drives the grinding disc 5 to reciprocate. When the rotating piece 71 rotates, the grinding disc 5 just leaves the platinum box. After the rotating piece 71 has rotated, the grinding disc 5 touches the sheet metal box for grinding.

[0041] After the polishing work is completed, the worker controls the movement of the brush 10 by the handle 102 to clean up the debris on the workbench 2. The debris falls into the collection box 11 along the rolling table 22 for unified collection. Then the worker takes out the collection box 11 to process the debris stored inside.

[0042] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
