Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and more specifically, to a polishing machine for sheet metal parts. Background Technology

[0002] Sheet metal parts are products manufactured using sheet metal processing techniques. Their most notable characteristic is that the thickness of any part is consistent. They are made from thin metal sheets (usually less than 6mm) such as steel, aluminum, and copper through a combination of cold working processes including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. Sheet metal parts are characterized by their light weight, high strength, electrical conductivity (suitable for electromagnetic shielding), low cost, and good mass production capabilities, and are widely used in various industries.

[0003] Currently, after sheet metal parts are processed and formed, they need to be polished using a polishing machine to ensure a smooth surface. The polishing machine can clean the imperfections and burrs on the surface of the sheet metal parts, making them smooth and beautiful. However, most existing polishing machines can only polish sheet metal parts in one vertical direction. When polishing sheet metal parts that require polishing on multiple sides, it is necessary to adjust the placement direction of the sheet metal parts, making the entire polishing process inconvenient. Therefore, this utility model proposes a polishing machine for sheet metal parts. Utility Model Content

[0024] Please see Figure 1-4 A polishing machine for sheet metal parts includes a worktable 1. A lower slide rail module 2 is fixedly connected to the top of the worktable 1. A fixed seat 3 is slidably connected to the lower slide rail module 2. A positioning plate 4 and a clamping cylinder 5 are fixedly connected to the top of the fixed seat 3. A clamping plate 6 is fixedly connected to the output end of the clamping cylinder 5, and the clamping plate 6 corresponds to the positioning plate 4. A gantry frame 7 is fixedly connected to the top of the worktable 1. A lifting cylinder assembly 8 is fixedly connected to the top of the gantry frame 7, and the output end of the lifting cylinder assembly 8 extends through to... Inside the gantry 7, the output end of the lifting cylinder assembly 8 is fixedly connected to the upper slide rail module 9. The upper slide rail module 9 is equipped with a movable frame 10. Inside the movable frame 10, there is a rotating shell 11. A grinding motor 12 is fixedly connected inside the rotating shell 11. The output end of the grinding motor 12 is fixedly connected to a polishing disc 13, and the polishing disc 13 corresponds to the fixed base 3. An adjustment mechanism is provided on the movable frame 10. The adjustment mechanism is used to control the rotation of the rotating shell 11 to adjust the polishing angle of the sheet metal parts.

[0025] In this embodiment, when polishing sheet metal parts, the sheet metal parts are placed on the fixed base 3 between the clamping plate 6 and the positioning plate 4. The clamping cylinder 5 pushes the clamping plate 6 to move and cooperate with the positioning plate 4 to clamp and fix the sheet metal parts. Then, the lower slide rail module 2 drives the fixed base 3 to move the sheet metal parts below the polishing disc 13. The polishing motor 12 controls the polishing disc 13 to rotate. The lifting cylinder group 8 controls the upper slide rail module 9 to move down, so that the polishing disc 13 contacts the sheet metal parts fixed on the fixed base 3 for polishing. The upper slide rail module 9 drives the moving frame 10 to move, so that the polishing disc 13 moves to adjust the polishing position. After the top of the sheet metal parts is polished, the angle of the rotating shell 11 in the moving frame 10 is adjusted by the adjustment mechanism, so that the angle of the polishing disc 13 is adjusted to match the side end of the sheet metal parts. The polishing disc 13 polishes the side end of the sheet metal parts in the same way.

[0026] Specifically, the adjustment mechanism includes two gears 141, a screw 142, a nut 143, an adjustment frame 144, and two racks 145. The two gears 141 are rotatably connected to the symmetrical side walls of the movable frame 10, and the ends of the two gears 141 that are close to each other are fixedly connected to the rotating housing 11. The screw 142 is rotatably connected to the movable frame 10. The nut 143 is threaded to the circumferential surface of the screw 142. The adjustment frame 144 is fixedly connected to the outer surface of the nut 143. The two racks 145 are fixedly connected to the bottom end of the adjustment frame 144, and the two racks 145 are located at the symmetrical side ends of the rotating housing 11 and mesh with the two gears 141.

[0027] In this embodiment, the two gears 141 are coaxially arranged. When adjusting the grinding angle of the polishing disc 13, the screw 142 is rotated, causing the nut 143 to move the adjusting frame 144. The adjusting frame 144 moves the two racks 145, and the two racks 145 rotate the two gears 141, thereby driving the rotating shell 11 to adjust the angle and complete the adjustment of the grinding angle of the polishing disc 13.

[0028] Specifically, the top wall of the movable frame 10 is fixedly connected to a fixed rod group 15, and the adjusting frame 144 is slidably connected to the circumferential surface of the fixed rod group 15.

[0029] In this embodiment, the fixing rod group 15 is used to assist the movement of the adjusting frame 144, so that the up and down movement of the adjusting frame 144 and the nut 143 remains stable, thereby improving the angle adjustment effect of the polishing disc 13.

[0030] Specifically, a detection camera 16 is fixedly connected to one side of the mobile frame 10, and the detection camera 16 corresponds to the fixed base 3.

[0031] In this embodiment, the detection camera 16 is used to detect the placement of sheet metal parts, which facilitates the determination of the position of sheet metal parts.

[0032] Specifically, a slide rail assembly 17 is fixedly connected to the top of the workbench 1, and a slide block assembly 18 is fixedly connected to the bottom of the fixed base 3, with the slide block assembly 18 slidably connected to the slide rail assembly 17.

[0033] In this embodiment, the fixed base 3 slides on the slide rail assembly 17 via the slide block assembly 18. The slide rail assembly 17 and the slide block assembly 18 assist the fixed base 3 in moving, ensuring the stability of the fixed base 3 when moving the sheet metal parts.

[0034] Working principle: When grinding and polishing sheet metal parts, the sheet metal parts are placed on the fixed base 3 between the clamping plate 6 and the positioning plate 4. The clamping cylinder 5 pushes the clamping plate 6 to cooperate with the positioning plate 4 to clamp and fix the sheet metal parts. According to the position of the sheet metal parts to be polished, the screw 142 is rotated, which causes the nut 143 to drive the adjusting frame 144 to move. The adjusting frame 144 drives the two racks 145 to move. The two racks 145 cause the two gears 141 to rotate, thereby driving the rotating shell 11 to adjust the angle, so that the polishing... The optical disc 13 corresponds to the end face of the sheet metal part to be polished. Then, the lower slide rail module 2 controls the fixed seat 3 to move, so that the sheet metal part moves on the fixed seat 3 corresponding to the polishing disc 13. The lifting cylinder group 8 controls the upper slide rail module 9 to lift, so that the polishing disc 13 moves along the Y axis. The upper slide rail module 9 drives the moving frame 10 to move, so that the polishing disc 13 moves along the X axis. During the movement of the polishing disc 13, it contacts the end face of the sheet metal part. The grinding motor 12 drives the grinding motor 12 to rotate and grind and polish the sheet metal part.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
