Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a burr removal device for die-cast products. Background Technology

[0002] In the field of metal processing, die casting is a common forming process. Molten metal is injected into a mold under high pressure to obtain die castings with specific shapes and sizes. However, during the die casting process, due to factors such as the flow of molten metal and the structure of the mold, burrs often form on the edges or surfaces of the die castings. These burrs not only affect the appearance quality of the die castings, but may also bring safety hazards during subsequent assembly and use, such as scratching operators or damaging other parts that work with them.

[0003] Chinese Patent Publication No. CN221870209U discloses a burr removal device for die-cast products, relating to the field of mold processing technology. The device includes a main body and a burr removal mechanism. A control panel is located on one side of the main body, a water tank is located behind the control panel, a water pump is located on top of the water tank, a hose is connected above the water pump, and a first motor is located above the hose. The burr removal mechanism is located inside the main body. By setting a first rotating shaft, when burrs need to be removed from die-cast products with complex curves or angles, a second motor is activated. The second motor drives a turntable to rotate via the first rotating shaft, which in turn drives a grinding blade to rotate. A third motor drives a second rotating shaft to rotate, which in turn drives a protective shell to rotate, thereby adjusting the grinding angle of the grinding blade to meet the burr removal needs of die-cast products with different shapes and requirements, increasing the flexibility of the device.

[0004] The aforementioned patent documents still have the following defects in practice:

[0005] The grinding blade can only adjust its angle through the rotating shaft and protective shell, and cannot handle multiple burrs at the same time, resulting in low grinding efficiency for complex curved surfaces. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figures 1-2 As shown, a burr removal device for die-cast products includes four legs 1. The upper ends of the four legs 1 are fixedly connected to a housing 2. A rotating mechanism 3 is rotatably connected to the upper part of the housing 2. An adjusting mechanism 6 is fixedly connected to the upper right part of the housing 2. A grinding mechanism 5 is installed in the middle of the adjusting mechanism 6. A fixing mechanism 1 4 is fixedly connected to the upper part of the rotating mechanism 3. Four fixing mechanisms 2 7 are fixedly connected to the middle of the fixing mechanism 1 4.

[0026] In this embodiment, the cylindrical die-casting part is placed on the upper end of the rotating mechanism 3. The fixing mechanism 4 is adjusted, and the fixing mechanism 4 drives the fixing mechanism 7 to fix the cylindrical die-casting part. Then, the adjusting mechanism 6 and the grinding mechanism 5 are adjusted, and the grinding mechanism 5 is aligned with the position of the cylindrical die-casting part that needs to be ground. The grinding mechanism 5 and the rotating mechanism 3 are started. The rotating mechanism 3 drives the cylindrical die-casting part to rotate, and the grinding mechanism 5 drives the grinding stone to rotate. After the die-casting part is ground, the rotating mechanism 3 and the grinding mechanism 5 are turned off, and the cylindrical die-casting part is taken out.

[0027] To adjust the position of polishing block 53, refer to... Figure 3 The adjustment mechanism 6 includes a movable frame 64, the lower end of which is fixedly connected to the upper right part of the outer shell 2. A fixed frame 61 is slidably connected to the outer surface of the movable frame 64. A threaded rod 62 is threadedly connected to the lower part of the fixed frame 61. A nut 63 is threadedly connected to the front part of the threaded rod 62. A rectangular groove is opened on the upper part of the fixed frame 61. The lower end of the fixed frame 61 is concave. The rear part of the concave part of the fixed frame 61 is slidably connected to the outer surface of the threaded rod 62. The front part of the concave part of the fixed frame 61 is threadedly connected to the front part of the threaded rod 62.

[0028] During implementation, loosen the threaded rod 62, move the fixed frame 61, and move the fixed frame 61 along the moving frame 64. Adjust the distance between the fixed frame 61 and the axis of the rotating mechanism 3. After adjusting to the appropriate position, rotate the threaded rod 62 to press and fix the concave plate at the lower end of the fixed frame 61. Then rotate the nut 63 to fix the position of the threaded rod 62 again to prevent the threaded rod 62 from loosening due to vibration.

[0029] For further details, please refer to [link / reference]. Figure 3The grinding mechanism 5 includes a fixed plate 54. The right side of the fixed plate 54 is slidably connected to the fixed frame 61. The right side of the fixed plate 54 is threadedly connected to a threaded rod 55. The left side of the threaded rod 55 is threadedly connected to a nut 56. The upper left side of the fixed plate 54 is fixedly connected to a motor 51. The output end of the motor 51 is fixedly connected to a connecting rod 52. The lower end of the connecting rod 52 is fixedly connected to a grinding block 53.

[0030] During implementation, loosen the threaded rod 55 to move the fixing plate 54 up and down along the fixing frame 61. After adjusting the height of the fixing plate 54, rotate the threaded rod 55 to press and fix the two plates on the right side of the fixing plate 54 against the fixing frame 61. Then rotate the nut 56 to fix the position of the threaded rod 55 again to prevent the threaded rod 55 from loosening due to vibration. The fixing plate 54 drives the connecting rod 52 to move up and down, and the motor 51 drives the connecting rod 52 and the grinding block 53 to move up and down. The grinding block 53 has a T-shaped cross section, so that when the motor 51 drives the grinding block 53 to rotate through the connecting rod 52, it can simultaneously grind the upper end face and the arc surface of the cylindrical die casting.

[0031] Example 2: To facilitate rotation of the die-cast part and ensure complete grinding, refer to... Figure 4 The rotating mechanism 3 includes a rotating disk 31 and a motor 36. The outer surface of the rotating disk 31 is rotatably connected to the upper part of the outer shell 2. A sleeve 33 is fixedly connected to the lower end of the rotating disk 31. A number of teeth 34 are arranged in a ring on the lower part of the outer surface of the sleeve 33. The lower end of the motor 36 is fixedly connected to the bottom wall of the outer shell 2. A gear 35 is fixedly connected to the outer surface of the output end of the motor 36. The gear 35 meshes with the teeth 34. The rotating disk 31 is provided with four strip grooves 32.

[0032] During implementation, motor 36 is started, which drives gear 35 to rotate. Gear 35 drives sleeve 33 to rotate through teeth 34. Sleeve 33 drives rotating disk 31 to rotate. Rotating disk 31 drives the die-casting part fixed on the upper end of rotating disk 31 to rotate, so that the upper part of the die-casting part is polished.

[0033] For securing the die-cast parts, see [reference] Figure 5 The fixing mechanism 4 includes a fixing sleeve 41, which is fixedly connected to the middle of the lower end of the rotating disk 31. Several protrusions 42 are fixedly connected to the outer surface of the fixing sleeve 41. A threaded rod 44 is threadedly connected to the inner surface of the fixing sleeve 41. A fixing rod 46 is fixedly connected to the lower end of the threaded rod 44. An arc plate 45 is fixedly connected to the middle of the outer surface of the fixing rod 46. A movable sleeve 43 is rotatably connected to the upper part of the outer surface of the fixing rod 46.

[0034] During implementation, the fixed sleeve 41 is fixedly connected to the rotating disk 31. Due to the presence of the protrusion 42, the movable sleeve 43 can move up and down along the fixed sleeve 41. At the same time, the fixed sleeve 41 can also drive the movable sleeve 43 to rotate. The bottom end of the movable sleeve 43 is located between the threaded rod 44 and the fixed rod 46. Rotating the fixed rod 46 causes the threaded rod 44 to rotate. The threaded rod 44 and the arc plate 45 cooperate to drive the movable sleeve 43 to move up and down.

[0035] For further details, please refer to [link / reference]. Figure 5 The second fixing mechanism 7 includes a first connecting block 71, which is fixedly connected to the outer surface of the movable sleeve 43. A connecting plate 72 is rotatably connected to the end of the first connecting block 71 away from the movable sleeve 43. A second connecting block 73 is rotatably connected to the end of the connecting plate 72 away from the first connecting block 71. A second fixing plate 74 is fixedly connected to the end of the second connecting block 73 away from the connecting plate 72. A rubber block 75 is fixedly connected to the upper part of the end of the second fixing plate 74 near the first fixing mechanism 4. The middle part of the second fixing plate 74 is slidably connected to the rotating disk 31.

[0036] During implementation, the movable sleeve 43 drives the connecting block 71 to move up and down, and the fixed plate 74 slides in connection with the strip groove 32. Therefore, when the connecting block 71 moves upward, the connecting block 71 drives the fixed plate 74 to move along the strip groove 32 through the connecting plate 72 and the connecting block 73. The four fixed plates 74 move closer to or further away from the axis of the rotating mechanism 3 at the same time to fix the die casting. The rubber block 75 increases the friction of the fixed plate 74 when fixing the die casting, and can also prevent the hard friction of the fixed plate 74 on the die casting from causing damage to the die casting.

[0037] 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 illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
