Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, specifically relating to a double-sided deburring device for sheet metal parts. Background Technology

[0002] In sheet metal processing, deburring is a crucial step in ensuring product quality, but traditional techniques have significant limitations. Manual grinding relies on workers using brushes and angle grinders, resulting in high labor intensity, low efficiency, and inconsistent quality due to varying worker skill levels, making it unsuitable for large-scale production. While mechanical grinding improves batch processing efficiency, it leaves blind spots for complex-shaped sheet metal parts, leading to incomplete burr removal. Existing single-sided deburring devices, although partially automated, still have shortcomings: they require manual flipping for further processing, a cumbersome process that results in low production efficiency; and they lack automatic chip removal mechanisms, leading to metal shavings accumulating and affecting processing and product quality, while increasing manual cleaning costs.

[0003] With the expanding application of sheet metal parts in the automotive, aerospace, and other fields, stringent requirements have been placed on processing precision and efficiency. Traditional and single-sided deburring technologies can no longer meet these demands, making the development of efficient and reliable double-sided deburring devices an urgent industry need to achieve the goals of improving quality and efficiency while reducing costs.

[0015] like Figure 1As shown, the double-sided deburring device for sheet metal parts includes a front grinding mechanism 1, a back grinding mechanism 2, a lower fixed plate 3, and an upper fixed plate 4. The lower fixed plate 3 has first slide rails 5 on both sides, and first sliders 6 are mounted on the first slide rails 5. The first sliders 6 are fixedly connected to the lower fixed plate 3. One end of the first slide rail 5 is designated as a front grinding station 7, and the other end as a back grinding station 8. The front grinding mechanism 1 is located above the front grinding station 7, and the back grinding mechanism 2 is located below the back grinding station 8. The front grinding mechanism 1 and the back grinding mechanism 2 have the same structure. The front grinding mechanism 1 includes a polishing disc 9, which is driven to rotate by a rotary motor 10 and moved by a three-axis displacement mechanism. The polishing disc 9 in the front grinding mechanism 1 is vertically downward, while the polishing disc 9 in the back grinding mechanism 2 is vertically upward. The upper fixing plate 4 is located above the back grinding mechanism 2. The lower surface of the upper fixing plate 4 is evenly spaced with several negative pressure adsorption holes 11. The upper fixing plate 4 has a vacuum chamber inside, and the negative pressure adsorption holes 11 are connected to the vacuum chamber. The vacuum chamber is connected to a vacuum pumping device. The upper fixing plate 4 is driven to move up and down by a first lifting drive mechanism 12. The sheet metal part is placed on the lower fixing plate 3, and the three-axis displacement mechanism drives the polishing disc 9 of the front grinding mechanism 1 to descend and grind the front of the sheet metal part along a certain grinding path to remove burrs. Then, the polishing disc 9 of the front grinding mechanism 1 rises, and the lower fixing plate 3 moves the sheet metal part to the back grinding station 8. The upper fixing plate 4 descends and fits against the upper surface of the sheet metal part, using the negative pressure generated in the negative pressure suction holes 11 on the upper fixing plate 4 to hold the sheet metal part in place. After the upper fixing plate 4 moves the sheet metal part upwards a certain distance, the lower fixing plate 3 moves back to the front grinding station 7. The three-axis displacement mechanism drives the polishing disc 9 of the back grinding mechanism 2 to move upwards, grinding and deburring the back of the sheet metal part. The two ends of the first slide rail 5 can be extended appropriately, thus further providing space for loading and unloading stations.

[0016] Furthermore, the lower fixed plate 3 is driven by a moving drive mechanism to move back and forth between the front grinding station 7 and the back grinding station 8.

The movement of the lower fixed plate 3 can be driven by traditional linear displacement drive methods such as cylinders or motors driving lead screws.

[0018] Furthermore, the upper surface of the lower fixing plate 3 is evenly spaced with a plurality of negative pressure adsorption holes 11, and the interior of the lower fixing plate 3 is provided with a vacuum chamber. The negative pressure adsorption holes 11 are connected to the vacuum chamber, and the vacuum chamber is connected to a vacuum pumping device. After the sheet metal part is placed on the lower fixing plate 3, the negative pressure generated by the negative pressure adsorption holes 11 on the lower fixing plate 3 is used to hold the sheet metal part in place and fix it to prevent it from slipping during the deburring process.

[0019] Furthermore, the three-axis displacement mechanism includes a lifting plate 15, a first movable plate 16, and a second movable plate 17. The lifting plate 15 is driven to move up and down by a second lifting drive mechanism 18.

The first movable plate 16 is fixedly connected to the second slider 20, and the second slider 20 is driven to move on the second slide rail 19 by a second translation drive mechanism 21. A third slide rail 22 is provided on the first movable plate 16, and a third slider 23 is installed on the third slide rail 22. The second movable plate 17 is fixedly connected to the third slider 23, and the third slider 23 is driven to move on the third slide rail 22 by a third translation drive mechanism 24. A rotary motor 10 is fixedly installed on the second movable plate 17. The second slide rail 19 and the third slide rail 22 are arranged perpendicularly, and the third slide rail 22 and the first slide rail 5 are arranged parallel to each other. The three-axis displacement mechanism provides X-axis, Y-axis, and Z-axis displacement to the polishing disc 9, and can grind, polish, and deburr the sheet metal surface according to a set program. The second lifting drive mechanism 18 and the first lifting drive mechanism 12 have the same structure, both being electric push rods or cylinders. Guide rods are fixedly connected to the four sides of the lifting plate 15 and the four sides of the upper fixed plate 4. Guide sleeves are fitted on the guide rods, and the guide sleeves, electric push rods, or cylinders are fixedly installed.

[0020] Furthermore, the second translation drive mechanism 21 includes a lead screw controlled by a motor, and the third translation drive mechanism 24 includes a lead screw controlled by a motor. The motor controls the rotation of the lead screw, and a lead screw pair is provided on the lead screw, which is fixedly connected to the second slider 20 or the third slider 23.
