Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a polishing equipment for automotive metal parts. Background Technology

[0002] After being processed and shaped, sheet-shaped metal workpieces often have burrs or scratches on their surface, which affect their use. Therefore, a polishing machine is needed to polish the surface of such sheet-shaped metal workpieces.

[0003] Chinese utility model patent (authorization announcement number: CN219599026U, title: A polishing machine with an easy-to-change polishing head) includes a grinder, a connector, and a grinding head. The connector is fixedly connected to the left side of the bottom of the grinder, the grinding head is located at the bottom of the connector, and a replacement mechanism is fixedly connected to the top of the grinding head. This utility model, by setting a replacement mechanism, allows for quick replacement of the grinding head during use. Different grinding heads are required when grinding different positions of the blades, allowing for control of grinding precision. This solves the problem of existing handheld grinders requiring rotating screws to fix the grinding head when changing the grinding head, which is cumbersome and time-consuming, making it inconvenient to use. It offers the advantage of greater ease of use, but manual polishing is labor-intensive and inefficient. Utility Model Content

[0023] like Figure 1 and2 As shown, an automotive metal polishing device includes a belt conveyor 1, a geared motor 2, a driven pulley 3, and a closed-end sanding belt 4. A portal frame 5 is fixed on the frame of the belt conveyor 1, spanning the belt of the conveyor 1. The geared motor 2 is fixed on the portal frame 5, and a drive pulley 6 is mounted on the shaft of the geared motor 2. The driven pulley 3 is rotatably mounted on the portal frame 5. The sanding belt 4 is used to link the driven pulley 3 and the drive pulley 6. A swing arm 7 is hinged to the portal frame 5, and a nitrogen spring 8 is hinged to the middle of the swing arm 7. The other end of the nitrogen spring 8 is hinged to the portal frame 5. A tensioning pulley 9 is rotatably mounted on the swing arm 7 to tension the sanding belt 4. A hydraulic cylinder 10 is fixed to the inner side of the top. A pair of pressure rods 11 are hinged to the piston rod of the hydraulic cylinder 10. An adjusting component is provided between the pair of pressure rods 11 to control the included angle between them. A pressure wheel 12 is rotatably mounted on the end of the pressure rod 11 away from the hydraulic cylinder 10. The pressure wheel 12 is used to press the sanding belt 4 against the belt conveyor 1. The belt conveyor 1 transports the sheet metal parts to the area below the sanding belt 4, removes the burrs, and then transports them to the next workstation. This reduces the labor intensity of workers and improves polishing efficiency. At the same time, the spacing between the pressure wheels 12 pressing down on the sanding belt 4 is adjustable to accommodate workpieces of different sizes for polishing, thus increasing the processing range of the workpieces.

[0024] In this embodiment, as Figure 1 and 2 As shown, there are two hydraulic cylinders 10, which are located on both sides of the conveying center line of the belt conveyor 1. The two hydraulic cylinders 10 can be used to process two different sizes of sheet metal parts at the same time, and the two hydraulic cylinders 10 can also be used to process a large sheet metal part at the same time, which makes the use more versatile.

[0025] In this embodiment, as Figure 3 As shown, the adjusting component includes a pair of lead screws 13 with opposite directions of rotation and a threaded sleeve 14. The pair of lead screws 13 are respectively hinged to two pressure rods 11. The internal threads at both ends of the threaded sleeve 14 have opposite directions of rotation. The threaded sleeve 14 is used to connect to the hinged pair of lead screws 13. Rotating the threaded sleeve 14 can adjust the angle between the two pressure rods 11. The structure is simple and easy to use.

[0026] In this embodiment, as Figure 1 and 2 As shown, a pair of rollers 15 are also rotatably mounted on the frame. The rollers 15 are used to press the metal parts conveyed on the belt conveyor 1. The gantry frame 5 is located between the pair of rollers 15 to prevent the sanding belt 4 from moving laterally when grinding the metal parts, thus affecting the polishing quality.

[0027] In this embodiment, as Figure 4As shown, a support base 16 is fixed on the frame. A groove is opened on the support base 16 along the vertical direction. The end of the roller 15 is slidably installed in the groove through the bearing seat 17. A spring 18 is also installed in the groove. The spring 18 is used to press the bearing seat 17 against the frame, which can automatically adapt to the polishing of sheet metal parts of different thicknesses.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
