[0002] Sheet metal parts are widely used in industrial production, and their surface quality directly affects the assembly accuracy and performance of products. Currently, the surface treatment of sheet metal parts mainly includes processes such as stamping, bending, welding, and grinding. Among these, grinding is a key step in improving surface smoothness and dimensional accuracy. With the development of industrial automation, large enterprises often use robotic arms and automated equipment to grind sheet metal parts. However, due to the high purchase and maintenance costs of robotic arms and automated equipment, most small and medium-sized enterprises still use handheld pneumatic or electric grinders. Compared to robotic arms and automated equipment, handheld or electric grinders have lower operating costs and higher flexibility, and can adapt to different types of sheet metal parts.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figures 1 to 5The precision grinding device for sheet metal parts shown includes a mounting base 1, a rotating platform 4 mounted on the upper side of the mounting base 1, multiple sets of vacuum suction cups 41 mounted on the surface of the rotating platform 4 and the mounting base 1, a support frame 11 fixedly connected to the rear side of the mounting base 1, a guide component mounted on the upper end of the support frame 11, the guide component including a first guide rail 14, a first sliding sleeve 15, a second guide rail 16, a second sliding sleeve 17, an electric cylinder 18, a telescopic rod 19 and a connecting seat 110, a universal joint 3 mounted on the lower side of the connecting seat 110, a grinding machine mounted on the lower side of the universal joint 3, and the grinding machine including an equipment box 2, a motor 23, a spindle 24 and a grinding head 25.

[0024] The vacuum suction cup 41 is connected to a vacuum pump via a pipe. The vacuum pump controls the vacuum suction cup 41. During the grinding of sheet metal parts, the sheet metal parts are placed on the upper side of the mounting base 1 and the rotating platform 4. Multiple sets of vacuum suction cups 41 are used to adhere and fix the sheet metal parts. Then, the grinding machine is used for grinding. In addition, during the grinding of curved sheet metal parts, the sheet metal parts are fixed on the upper side of the vacuum suction cup 41. During the grinding process, the angle of the sheet metal parts is adjusted by rotating the rotating platform 4 so that the un-grinded side of the sheet metal parts faces the operator, thereby improving grinding efficiency and grinding accuracy.

[0025] Meanwhile, during the grinding process, the grinding machine is suspended by the guide component, so that the grinding machine is suspended above the sheet metal part. At this time, only the position of the grinding machine needs to be adjusted to grind the surface of the sheet metal part. The workers do not need to keep the grinding machine suspended for a long time, which reduces the labor intensity of the workers and improves the grinding accuracy.

[0026] In a preferred embodiment, the motor 23 is fixedly installed inside the equipment box 2, the spindle 24 is fixedly connected to the output end of the motor 23 via a coupling, the grinding head 25 is fixedly installed at the lower end of the spindle 24, and a handle 21 is fixedly connected to the side of the equipment box 2. Multiple control buttons 22 are installed on the surface of the handle 21, and the control buttons 22 are electrically connected to the controllers of the electric cylinder 18 and the motor 23, respectively.

[0027] In addition, during grinding, the motor 23 is started by the control button 22. The output end of the motor 23 drives the grinding head 25 to rotate through the spindle 24 to grind the surface of the sheet metal part. The grinding head 25 is detachable and replaceable to facilitate different grinding conditions.

[0028] See Figures 1 to 4A support plate 12 is fixedly connected to the upper end of the support frame 11, and fixed plates 13 are fixedly connected to both ends of the support plate 12. The two ends of the first guide rail 14 are fixedly connected to the two sets of fixed plates 13 respectively. The first sliding sleeve 15 is slidably connected to the first guide rail 14. The rear end of the second guide rail 16 is fixedly connected to the first sliding sleeve 15. The second sliding sleeve 17 is slidably connected to the surface of the second guide rail 16. The electric cylinder 18 is fixedly installed inside the second sliding sleeve 17. The telescopic rod 19 is fixedly connected to the lower end of the piston rod in the electric cylinder 18. The connecting seat 110 is fixedly connected to the lower end of the telescopic rod 19.

[0029] Specifically, the first sliding sleeve 15 slides left and right on the surface of the first guide rail 14, thereby adjusting the left and right positions of the second guide rail 16 and the grinder, and the second sliding sleeve 17 slides back and forth on the surface of the second guide rail 16, thereby adjusting the position of the grinder back and forth.

[0030] At the same time, in the initial state, the piston rod in the electric cylinder 18 retracts inward, which, together with the telescopic rod 19, suspends the grinder in mid-air. After the sheet metal part is placed on the upper side of the mounting base 1 and the rotating platform 4, the electric cylinder 18 is activated to move the grinder downward, so that the grinding head 25 in the grinder contacts the surface of the sheet metal part. At this time, the grinder is activated to grind the sheet metal part. During the grinding process, the first guide rail 14, the first sliding sleeve 15, the second guide rail 16 and the second sliding sleeve 17 cooperate to move the grinder to any position on the surface of the sheet metal part.

[0031] As a preferred embodiment, the universal joint 3 includes a universal ball 31 and a ball seat 32. The universal ball 31 and the ball seat 32 are rotatably connected. The upper end of the universal ball 31 is fixedly connected to the connecting seat 110, and the lower end of the ball seat 32 is fixedly connected to the upper end of the equipment box 2.

[0032] In addition, the telescopic rod 19 has a certain telescopic space, which allows the grinder to be raised a certain distance without starting the electric cylinder 18. At the same time, under the action of the universal joint 3, the grinder can rotate around the lower side of the universal ball 31 to adjust the angle of the grinding head 25. During the grinding of the curved sheet metal parts, the telescopic rod 19, together with the universal joint 3, can make fine adjustments to the height and angle of the grinder, thereby improving the grinding accuracy of the curved sheet metal parts.

[0033] The working principle of this utility model is as follows: The sheet metal part is fixed to the upper side of the mounting base 1 and the rotating platform 4 by the vacuum suction cup 41. The electric cylinder 18 is started to move the grinder downward, so that the grinding head 25 in the grinder contacts the surface of the sheet metal part. At this time, the motor 23 is started. The motor 23 and the main shaft 24 work together to drive the grinding head 25 to rotate and grind the sheet metal part. At this time, the first guide rail 14, the first sliding sleeve 15, the second guide rail 16 and the second sliding sleeve 17 work together to move the grinder to any position on the surface of the sheet metal part for grinding. During the process, the guide component suspends the grinder at the same height on the sheet metal surface, improving the grinding accuracy of the grinder. Moreover, the operator only needs to adjust the position of the grinder, reducing the operator's workload and preventing hand fatigue. This allows for better control of the grinder and further improves grinding accuracy. At the same time, when grinding curved sheet metal parts, the telescopic rod 19 can slightly raise the grinder, and the angle of the grinder can be adjusted through the universal joint 3, improving the grinding accuracy of curved sheet metal parts and enhancing the adaptability of the equipment.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
