Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy casting processing equipment, specifically to a deburring production equipment for aluminum alloy die castings. Background Technology

[0002] With the widespread application of aluminum alloy die castings in aerospace, automotive manufacturing, machining, and many other fields, the quality requirements for them are becoming increasingly stringent. Deburring is a crucial step in the production of aluminum alloy die castings. After die casting, burrs inevitably form on the surface of the aluminum alloy die casting. These burrs not only affect the appearance quality of the product but may also pose safety hazards during subsequent assembly and use, such as scratching operators or affecting the precision of fit between components.

[0003] Chinese patent CN201920887288 discloses a deburring device for aluminum alloy casting production and processing, comprising a platform, a support fixed to the bottom of the platform, a first motor fixed to the right side of the output end of a hydraulic cylinder, a grinding wheel fixed to the right end of the first motor, a square tube fixed to the top right side of the platform, a lifting assembly inside the square tube, and an intermittent mechanism on the left side of the square tube. While this patent achieves a close fit between the grinding wheel and the aluminum alloy casting through the cooperation of components such as springs, sliders, and hydraulic cylinders, thus improving the deburring effect and efficiency to some extent, the coordination of the lifting assembly and the intermittent mechanism is difficult to flexibly adjust to a suitable position and angle. For some aluminum alloy castings with complex shapes and irregular external contours, it cannot fully cover all surfaces of the casting for effective deburring, resulting in some burr residue and seriously affecting product quality.

[0004] Therefore, developing a grinding device that can better adapt to aluminum alloy castings with different external contours is of great practical significance. Utility Model Content

[0026] like Figure 1-4 As shown, this utility model provides a deburring production equipment for aluminum alloy die castings, including a support platform 1, a turntable motor 2 at the bottom of the support platform 1, a support frame 3 vertically mounted on one side of the support platform 1, a crossbeam 4 raised and lowered on the support frame 3, horizontally mounted clamping arms 5 slidably mounted on both sides of the crossbeam 4, and a grinding mechanism 6 slidably mounted on the clamping arms 5 along their extension direction. The grinding mechanism 6 includes an outer support structure 61 slidably mounted on the crossbeam 4, a connecting rod 62 slidably mounted inside the outer support structure 61, a grinding machine 63 mounted at one outward end of the connecting rod 62, and a spring 64 between the other end of the connecting rod 62 and the interior of the outer support structure 61.

[0027] In this embodiment, the crossbeam 4 has a through guide slot 41 and a threaded hole 42 in its middle section. A drive motor 31 is located at the bottom of the support frame 3, and a screw 32 is located at the output end of the drive motor 31. The screw 32 is threadedly connected to the threaded hole 42. By driving the screw 32 to rotate via the drive motor 31, the crossbeam 4 can be raised and lowered on the support frame 3, thereby adjusting the height of the grinding mechanism 6.

[0028] In this embodiment, one end of the clamping arm 5 is provided with a sliding sleeve 51, which slides on the crossbeam 4. A threaded hole 52 pointing towards the crossbeam 4 is provided through the sliding sleeve 51, and a limit bolt 53 is internally threaded into the threaded hole 52. By tightening or loosening the limit bolt 53, the position of the clamping arm 5 on the crossbeam 4 can be fixed or adjusted.

[0029] In this embodiment, a linear drive module 54 is provided on the clamping arm 5, and the moving block of the linear drive module 54 is connected to the outer support structure 61. The linear drive module 54 can push the grinding mechanism 6 to slide on the clamping arm 5, further adjusting the position of the grinding machine 63.

[0030] In this embodiment, the turntable motor 2 is a self-locking motor. The self-locking motor can maintain its current position when it stops rotating, ensuring the stability of the aluminum alloy die-cast parts on the support platform 1.

[0031] In this embodiment, a mounting bracket 7 is horizontally arranged at the top of the support frame 3. A pressing mechanism 8 is arranged on the mounting bracket 7 at the center of the bearing platform 1. The pressing mechanism 8 includes a vertically arranged sleeve 81, with an adjusting rod 82 internally threaded onto the sleeve 81. A pressure plate 83 is rotatably mounted on the lower end of the adjusting rod 82, and a locking nut 84 is also provided on the adjusting rod 82. The height of the pressure plate 83 can be adjusted by rotating the adjusting rod 82 to press the aluminum alloy die-casting part onto the bearing platform 1, and the position of the adjusting rod 82 is fixed by the locking nut 84.

[0032] In this embodiment, a toothed ring 11 with its teeth facing upwards is provided at the top edge of the bearing platform 1. The central axis of the toothed ring 11 coincides with the central axis of the turntable motor 2. A limit bracket 9 is provided on the side of the bearing platform 1. A vertically arranged sleeve 91 is provided on the limit bracket 9. A pressure rod 92 is provided inside the sleeve 91. A limit block 93 is provided at the bottom end of the pressure rod 92. The bottom surface of the limit block 93 is provided with teeth that match the toothed ring 11. A spring 94 is provided on the pressure rod 92 between the limit block 93 and the limit bracket 9. The outer side of the pressure rod 92 is provided with external threads. A limit nut 95 is provided on the pressure rod 92 and located above the limit bracket 9. A handle 96 is provided at the top of the pressure rod 92. By pulling up the handle 96, the limit block 93 can be separated from the toothed ring 11, and the bearing platform 1 can rotate freely. When the handle 96 is lowered, the limit block 93 engages with the toothed ring 11 under the action of the spring 94, restricting the rotation of the bearing platform 1.

[0033] The working principle of the above technical solution is as follows:

[0034] When it is necessary to grind the surface of the casting,

[0035] Step 1, placing the casting: Place the aluminum alloy die casting to be deburred on the support platform 1, and place a pad under the aluminum alloy die casting as needed to make the grinding surface vertical. Then pull up the handle 96 to separate the limit block 93 from the gear ring 11. Use the limit nut 95 to fix the position of the pressure rod 92. Rotate the adjusting rod 82 to lower the pressure plate 83 and press the aluminum alloy die casting onto the support platform 1. Then tighten the locking nut 84 to fix the adjusting rod 82. Then control the turntable motor 2 to rotate so that the grinding surface faces one of the grinding machines 63. Then turn off the turntable motor 2 to self-lock. Then adjust the limit nut 95 to make the limit block 93 engage with the gear ring 11.

[0036] The second step involves starting the drive motor 31, which drives the screw 32 to rotate, causing the crossbeam 4 to rise or fall on the support frame 3, adjusting the crossbeam 4 to a suitable height position; the linear drive module 54 pushes the grinding mechanism 6 to slide on the clamping arm 5, aligning the grinding machine 63 with the surface of the casting, loosening the limit bolt 53, sliding the sliding sleeve 51, adjusting the clamping arm 5 to a suitable position, and then tightening the limit bolt 53 to fix the clamping arm 5;

[0037] The third step is to start the grinding machine 63, control the rotation of the drive motor 31 through the controller to control the rise or fall of the crossbeam 4, and cooperate with the linear drive module 54 to push the grinding mechanism 6 to slide on the clamping arm 5 to perform grinding operations on the surface of the aluminum alloy die casting.

[0038] Fourth step: After grinding is completed, turn off the grinding machine 63, loosen the clamping mechanism 8, and remove the aluminum alloy die casting.

[0039] When it is necessary to grind the circumferential surface of the casting,

[0040] Step 1, placing the casting: Place the aluminum alloy die casting that needs to be deburred on the bearing platform 1, then pull up the handle 96 to separate the limit block 93 from the gear ring 11, use the limit nut 95 to fix the position of the pressure rod 92, rotate the adjusting rod 82 to lower the pressure plate 83 and press the aluminum alloy die casting onto the bearing platform 1, and then tighten the locking nut 84 to fix the adjusting rod 82.

[0041] The second step involves starting the drive motor 31, which drives the screw 32 to rotate, causing the crossbeam 4 to rise or fall on the support frame 3, adjusting the crossbeam 4 to a suitable height position; the linear drive module 54 pushes the grinding mechanism 6 to slide on the clamping arm 5, aligning the grinding machine 63 with the center position of the casting, loosening the limit bolt 53, sliding the sliding sleeve 51, adjusting the clamping arm 5 to a suitable position where the grinding machine 63 contacts the surface of the aluminum alloy casting, and then tightening the limit bolt 53 to fix the clamping arm 5;

[0042] The third step involves starting the grinding machine 63. The controller operates the turntable motor 2, which slowly rotates the support platform 1. This, along with the raising and lowering of the crossbeam 4, allows the grinding machine 63 to remove burrs from the casting surface. During the grinding process, spring 64 automatically adjusts the position of the grinding machine 63 according to the surface contour of the casting, ensuring full contact between the grinding machine 63 and the casting surface.

[0043] Fourth step: After grinding is completed, turn off the grinding machine 63, loosen the clamping mechanism 8, and remove the aluminum alloy die casting.

[0044] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
