Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and in particular to a burr removal component. Background Technology

[0002] Half-shaft gears are key components of automotive differentials, used to transmit power from the differential to the wheels, enabling differential rotation of the two wheels during cornering. Because burrs easily form on the edges after gear machining (such as milling and hobbing), if not cleaned, they can cause jamming during meshing, accelerated wear, and even abnormal noises and transmission failure, affecting driving safety and gear lifespan. Therefore, a grinding process is required before the gears leave the factory.

[0003] Currently, in gear deburring operations, workers fix the gear on a rotary table and use rotating tools such as brushes and grinding wheels to grind the gear edges. However, because dead corners and residues easily accumulate on the bottom and sides of the gear, the position of the rotating tools needs to be repeatedly adjusted manually, resulting in low grinding efficiency in actual operation.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a burr cleaning assembly, including a positioning frame and a grinding frame, with the grinding frame arranged on the left and right sides of the positioning frame;

[0023] The positioning frame includes a worktable 1, a turntable 2 at the upper end of the worktable 1, a first support 6 at the lower end of the worktable 1, the turntable 2 is rotatably connected to the worktable 1, the upper end of the turntable 2 is provided with multiple sets of rotating clamps for fixing gears, and the lower end of the worktable 1 is provided with an intermittent transmission component for controlling the rotation of the turntable 2.

[0024] The grinding machine frame includes two second supports 7. The upper end of the second support 7 is provided with a rotating ring 8. The rotating ring 8 is rotatably set inside the second support 7. The rotating ring 8 is provided with a brush roller structure for cleaning burrs on the gears on the side near the turntable 2. The brush roller structure is offset from the rotating clamp.

[0025] The gears that need to be deburred are fixed in sequence on each of the rotating clamps. The rotating clamps drive the workpiece to rotate. While the workpiece is rotating, the second bracket 7 grinds the top of the workpiece from the left and right sides of the turntable 2 through the brush roller structure. After the top grinding is completed, the rotating ring 8 will rotate to adjust the grinding angle and position of the brush roller structure, and grind the sides and bottom of the workpiece in sequence. The grinding efficiency is very high.

[0026] It is worth explaining in detail that the first support 6 is fixedly installed at the lower end of the workbench 1, and the second support 7 is fixedly installed on the left and right sides of the first support 6. The first support 6 is used to support the workbench 1, and the second support 7 is used to support the rotating ring 8. The second support 7 is fixedly installed with the first support 6 to connect the two sets of frames into a whole, thereby improving the stability of the entire device structure.

[0027] Regarding rotary clamping:

[0028] The rotary clamping device includes a positioning seat 3, which is fixedly mounted on the edge of a turntable 2. An electric chuck 4 is provided on the upper end of the positioning seat 3 and is rotatably connected to the positioning seat 3. A first motor 5 is fixedly mounted on the lower end of the positioning seat 3 and is fixedly connected to the electric chuck 4 at its output end.

[0029] The electric chuck 4 has two clamping blocks at its top. When fixing the workpiece, the gear is placed on the outside of the two clamping blocks. The motor inside the electric chuck 4 drives the internal mechanical structure to open the two clamping blocks outward, thus fixing the gear. The electric chuck 4 is a commonly used material handling gripper in engineering equipment; specific models will not be described in detail. After fixing the gear, the first motor 5 controls the electric chuck 4 to rotate on the upper end of the positioning seat 3. The positioning seat 3 rotates synchronously, causing the gear to rotate synchronously, which, together with the rotating brush roller structure, cleans the burrs on the gear surface.

[0030] Regarding intermittent transmission components:

[0031] The intermittent transmission component includes a grooved wheel 10 and a dial 11. The grooved wheel 10 and the dial 11 are rotatably mounted on the lower end of the worktable 1. The grooved wheel 10 is fixedly connected to the turntable 2 through a connecting shaft. The dial 11 is provided with a lever, which cooperates with a groove opened on the outer edge of the grooved wheel 10. A second motor 9 is fixedly mounted on the lower end of the worktable 1. The output end of the second motor 9 is fixedly connected to the dial 11.

[0032] The second motor 9 drives the dial 11 to rotate. As the dial 11 rotates, the lever at its end is inserted into the groove on the outside of the grooved wheel 10. When the dial 11 rotates one revolution, the lever slides along the groove, pushing the grooved wheel 10 to rotate one-quarter revolution, thereby achieving the intermittent movement of the turntable 2. During the intermittent movement, the turntable 2 switches the position of each positioning seat 3.

[0033] Regarding the rotation of rotating ring 8, please refer to the following instructions:

[0034] A ring gear 12 and a fourth motor 21 are located on the side of the rotating ring 8 away from the turntable 2. The ring gear 12 is sleeved on the outside of the rotating ring 8, and the rotating ring 8 is fixedly connected to the ring gear 12. A gear 20 is located below the ring gear 12, and the gear 20 meshes with the ring gear 12. The fourth motor 21 is fixedly installed inside the second bracket 7, and the output end of the fourth motor 21 is fixedly connected to the gear 20. The fourth motor 21 drives the gear 20 to rotate, and the gear 20 meshes with the ring gear 12 during rotation, thereby driving the rotating ring 8 to rotate. Since the brush roller structure is fixed to the rotating ring 8, the brush roller structure will also rotate when the rotating ring 8 rotates, adjusting the grinding position and angle.

[0035] Specifically, the brush roller structure includes a fixed base 15, which is detachably connected to one side of the rotating ring 8 via a fixing bolt 16. The axis of the fixed base 15 is offset from that of the rotating ring 8. An electric push rod 17 is fixedly installed at the upper end of the fixed base 15, and a third motor 18 is provided at the lower end of the fixed base 15. The output end of the electric push rod 17 is fixedly connected to the third motor 18. A grinding roller 19 is provided at the lower end of the third motor 18, and the grinding roller 19 is fixedly connected to the output end of the third motor 18.

[0036] The electric push rod 17 pushes the grinding roller 19 down, and the grinding roller 19 at the bottom of the third motor 18 contacts the upper end face of the gear fixed on the electric chuck 4. The turntable 2 controls the electric chuck 4 to rotate, and the third motor 18 controls the grinding roller 19 to rotate, completing the grinding of the upper end face of the gear. After the rotating ring 8 rotates 180°, the grinding roller 19 contacts the lower end face of the gear, realizing the grinding of the lower end face and side of the gear.

[0037] The fixing bolt 16 is fitted onto the bolt lugs on the left and right sides of the fixing seat 15. When the fixing seat 15 is removed from the rotating ring 8, the fixing bolt 16 is rotated to unscrew it from the bolt hole on the outside of the rotating ring 8.

[0038] In a preferred embodiment, a third support 13 is provided on the side of the second support 7 away from the turntable 2, and the third support 13 is fixedly connected to the second support 7. A conical hood 14 is provided in the center of the rotating ring 8, and the conical hood 14 is fixedly connected to the third support 13. The negative pressure dust extraction duct is connected through the conical hood 14. When the brush roller structure removes burrs from the gears, the tiny debris generated will be directly extracted through the conical hood 14, reducing pollution in the working environment.

[0039] How this application works:

[0040] The gears that need to be deburred are fixed in sequence on each of the rotating clamps. The rotating clamps drive the workpiece to rotate. While the workpiece is rotating, the second bracket 7 grinds the top of the workpiece from the left and right sides of the turntable 2 through the brush roller structure. After the top grinding is completed, the rotating ring 8 will rotate to adjust the grinding angle and position of the brush roller structure, and grind the sides and bottom of the workpiece in sequence. The grinding efficiency is very high.
