Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a multi-angle processing device for automotive aluminum alloy castings. Background Technology

[0002] In the automotive manufacturing industry, with the popularization of lightweight design concepts, aluminum alloy castings, due to their advantages of light weight, high strength, and corrosion resistance, are widely used in key components such as engine blocks, wheel hubs, and body frames. These components often require multi-angle drilling and milling operations in actual use to meet complex assembly and functional requirements. Existing automotive aluminum alloy casting processing equipment mostly adopts a fixed-station structure. When processing castings at different angles is required, operators must manually adjust the casting position or change tooling fixtures. This is not only cumbersome and inefficient, but also makes it difficult to guarantee the accuracy of each adjustment, easily leading to angular deviations. This not only reduces processing accuracy and affects the assembly accuracy between components, but may also increase production costs and extend the production cycle due to rework. Therefore, this utility model proposes a multi-angle processing device for aluminum alloy castings. Utility Model Content

[0003] The purpose of this utility model is to address the problem that in the background technology, most automotive aluminum alloy casting processing devices adopt a fixed station structure. When different angles need to be processed on the casting, the operator needs to manually adjust the position of the casting or change the tooling fixture. This is not only cumbersome and inefficient, but also makes it difficult to ensure the accuracy of each adjustment during the angle adjustment process, which is prone to angle deviation. This not only leads to a decrease in processing accuracy and affects the assembly accuracy between parts, but may also increase production costs and extend the production cycle due to rework. Therefore, this utility model proposes a multi-angle processing device for automotive aluminum alloy castings.

[0004] The technical solution of this utility model is as follows: A multi-angle machining device for automotive aluminum alloy castings, comprising: a base plate, on the upper surface of which a placement plate for placing aluminum alloy castings is fixedly mounted; an annular guide rail fixedly mounted on the upper surface of the base plate, the annular guide rail being sleeved on the outer wall of the placement plate; an electric drill for drilling holes in the aluminum alloy castings being mounted directly above the placement plate, the upper end of the electric drill being equipped with a cylinder; a set of guide blocks mounted on the upper surface of the annular guide rail, a limiting component for adjusting the drilling angle of the electric drill being mounted between the guide blocks; and a positioning component for limiting the aluminum alloy castings being fixedly mounted on the upper surface of the placement plate.

[0005] Optionally, the limiting component includes a set of guide frames fixedly disposed between the guide blocks, a guide slider slidably disposed between the guide frames, a limiting base plate fixedly disposed on the bottom surface of the guide slider, a fixed frame fixedly disposed on the upper end of the limiting base plate, guide grooves respectively opened on both sides of the fixed frame, a guide strip slidably disposed inside the guide groove, a limiting pressure plate fixedly connected to both ends of the guide strip, and an adjusting bolt rotatably disposed on the upper surface of the guide strip, the adjusting bolt being threadedly sleeved with the fixed frame.

[0006] Optionally, the positioning component includes a set of support plates fixedly disposed on the upper surface of the placement plate, wherein each support plate is threaded with an adjusting bolt, and one end of the adjusting bolt is rotatably connected to a clamping plate.

[0007] Optionally, a positioning bolt is threaded through one side of the guide block, and a positioning block is rotatably connected to one end of the positioning bolt. The positioning block is slidably connected to the annular guide rail.

[0008] Optionally, the outer ring surface of the guide frame is provided with a plurality of limiting grooves, and the inner ring surface of the limiting pressure plate is fixedly provided with a plurality of limiting blocks.

[0009] Optionally, an angle mark is provided on one side of the guide frame.

[0010] Optionally, the guide frame is configured with an arc-shaped structure.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This utility model achieves flexible and precise adjustment during multi-angle machining by using an arc-shaped guide frame in the limiting component, a slidable guide slider between the guide frames, a sliding fit between the guide groove and the guide strip, and a threaded connection between the adjusting bolt and the fixed frame. This avoids the tedious operation of manually adjusting the position of the casting or changing the tooling fixture, greatly improving the efficiency of multi-angle machining and shortening the machining time.

[0013] Furthermore, this invention utilizes a ring-shaped guide rail, a guide block, and a positioning bolt and positioning block structure on one side of the guide block, in conjunction with a limiting component, to precisely adjust the drill angle, achieving stable positioning of the drill during processing. Once the limiting component has adjusted the drill to the appropriate angle, the positioning bolt can be tightened, causing the positioning block to firmly abut against the ring-shaped guide rail, fixing the guide block at a specific position on the ring-shaped guide rail. This prevents the drill from shifting position during drilling, ensuring the accuracy of the drilling angle each time, avoiding the problem of decreased processing precision due to angle deviation, improving the processing quality of aluminum alloy castings, and reducing increased production costs and extended production cycles caused by rework.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Example

[0029] like Figure 1 and Figure 4 As shown, the present invention proposes a multi-angle processing device for automotive aluminum alloy castings, comprising: a base plate 1 made of high-strength steel with a flat and wear-resistant surface; a placement plate 2 for placing aluminum alloy castings is fixedly installed on the upper surface of the base plate 1 by welding; the surface of the placement plate 2 is treated with anti-slip treatment to ensure that the castings are placed stably.

[0030] Furthermore, an annular guide rail 3 is fixedly installed on the upper surface of the base plate 1. The annular guide rail 3 is forged from high-quality alloy steel, and its inner diameter is tightly fitted with the outer wall of the placement plate 2 to form a stable rotating connection structure. An electric drill 4 for drilling holes in aluminum alloy castings is installed directly above the placement plate 2. The electric drill 4 has strong power and can efficiently complete the drilling operation. The cylinder 5 installed at its upper end can flexibly adjust the lifting height of the electric drill 4.

[0031] Secondly, a set of guide blocks 6 are set on the upper surface of the annular guide rail 3. The guide blocks 6 are rectangular blocks with a positioning bolt 9 threaded through one side. One end of the positioning bolt 9 is rotatably connected to a positioning block 10. The positioning block 10 slides in contact with the annular guide rail 3. The position of the guide block 6 on the annular guide rail 3 can be fixed by tightening the positioning bolt 9.

[0032] like Figure 2 and Figure 3As shown, a limiting component 7 for adjusting the drilling angle of the electric drill 4 is provided between the guide blocks 6. The limiting component 7 includes a set of guide frames 71 fixedly installed between the guide blocks 6. The guide frames 71 have an arc-shaped structure and a smooth surface to facilitate the sliding of the guide slider 72. An angle mark 13 is clearly marked on one side for easy reading of the drilling angle. The guide slider 72 is slidably installed between the guide frames 71. A limiting base plate 73 is fixedly installed on the bottom surface of the guide slider 72, which provides stable support. A fixed frame 74 is fixedly installed at the upper end of the limiting base plate 73. Guide grooves 75 are opened on both sides of the fixed frame 74. A guide strip 76 is slidably installed inside the guide groove 75. Limiting pressure plates 77 are fixedly connected to both ends of the guide strip 76. An adjusting bolt 78 is rotatably installed on the upper surface of the guide strip 76. The adjusting bolt 78 is threadedly sleeved with the fixed frame 74. The position of the limiting pressure plate 77 can be controlled by rotating the adjusting bolt 78.

[0033] like Figure 1 and Figure 2 As shown, a positioning assembly 8 for limiting the position of the aluminum alloy casting is fixedly installed on the upper surface of the placement plate 2. The positioning assembly 8 includes a set of support plates 81 fixedly installed on the upper surface of the placement plate 2. The support plates 81 are perpendicular to the placement plate 2 and provide stable support. Adjusting bolts 82 are threaded through the support plates 81 respectively. One end of the adjusting bolt 82 is rotatably connected to a clamping plate 83. By rotating the adjusting bolt 82, the clamping plate 83 can be driven to clamp and limit the casting.

[0034] Furthermore, the outer ring surface of the guide frame 71 is provided with multiple limiting grooves 11, and the inner ring surface of the limiting pressure plate 77 is fixedly provided with multiple limiting blocks 12. The limiting blocks 12 and the limiting grooves 11 cooperate with each other to achieve precise positioning of the limiting component 7 after angle adjustment.

[0035] In this embodiment, the automotive aluminum alloy casting is placed on the surface of the placement plate 2 on the base plate 1. Then, the adjusting bolt 82 on the support plate 81 in the positioning assembly 8 is rotated. Since the adjusting bolt 82 is rotatably connected to the clamping plate 83, as the adjusting bolt 82 rotates, the clamping plate 83 will move towards the aluminum alloy casting until it is tightly clamped, ensuring that it will not be displaced during processing.

[0036] The guide block 6 is pushed to slide on the annular guide rail 3. Because the guide block 6 is connected to the limiting component 7, and the electric drill 4 is connected to the limiting component 7, the sliding of the guide block 6 will cause the electric drill 4 to move around the aluminum alloy casting on the placement plate 2, roughly moving the electric drill 4 to the position where drilling is required. After reaching the appropriate position, the positioning bolt 9 on one side of the guide block 6 is tightened. The positioning block 10 connected to the positioning bolt 9 will be pushed by the positioning bolt 9 to fit tightly against the annular guide rail 3, thereby fixing the position of the guide block 6.

[0037] When adjusting the drilling angle, rotating the adjusting bolt 78 causes the guide rail 76 to slide up and down within the guide grooves 75 on both sides of the fixed frame 74. Since the adjusting bolt 78 is threaded onto the fixed frame 74 and rotatably mounted on the upper surface of the guide rail 76, rotating the adjusting bolt 78 causes the guide rail 76 to slide up and down. Limiting plates 77 are fixedly connected to both ends of the guide rail 76, and the sliding of the guide rail 76 causes the limiting plates 77 to move. Simultaneously, because the guide frame 71 has an arc-shaped structure, the angle of the electric drill 4 changes as the limiting plates 77 move.

[0038] During the adjustment process, refer to the angle mark 13 set on one side of the guide frame 71. When the electric drill 4 reaches the required drilling angle, rotate the adjusting bolt 78 in the opposite direction. At this time, the limiting block 12 on the inner ring surface of the limiting pressure plate 77 will cooperate with the limiting groove 11 on the outer ring surface of the guide frame 71 to further fix the angle of the electric drill 4.

[0039] Start cylinder 5, which pushes electric drill 4 downward, and electric drill 4 begins to drill holes in the aluminum alloy casting.

[0040] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
