Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting of a reducer housing of a new energy vehicle, and in particular to a progressive high-precision sawing tool for a reducer housing of a new energy vehicle. Background Art
[0002] In casting production, due to process reasons, there are risers and runners on the casting body, which need to be removed after casting before they can continue to flow to the downstream process. In the prior art, the risers and runners on the casting are usually sawed off by manual sawing.
[0003] However, under the new industry changes such as the integration and lightweighting of the new energy vehicle industry, related casting products have begun to become larger and thinner, and inevitably the precision requirements for removing process risers and runners have begun to become higher. As the products become larger, the previous manual sawing method with a vertical saw is no longer applicable, and they can only be sawed with a large horizontal sawing machine. Since the position of the saw blade of the horizontal sawing machine cannot be adjusted, the product can only be placed on the equipment multiple times by manual operation to complete the sawing work. However, because the product is too large and the product is placed multiple times, it is easy to cause positioning failure. In the case of inconvenient operation by personnel, it is easy to cause quality problems such as over-cutting or inadequate sawing of the product, resulting in additional rework work or direct product scrapping, which is time-consuming and labor-intensive. In addition, during the production process of the mold, the product deviation caused by mold corrosion causes some precision tooling to fail, resulting in excessive sawing or inadequate sawing.

[0027] Figure 1-6 A specific embodiment of a progressive high-precision sawing tool for a reduction housing of a new energy vehicle is shown, comprising a base portion, a clamping portion, and a tool protection portion.
[0028] like Figure 2 As shown, the base part includes a bottom plate 1 and a limit block, a slide rail 3, a corner cylinder 4, and a moving cylinder 5 arranged on the bottom plate 1. The bottom plate 1 is the base of the entire tooling, and is provided with a waist-shaped hole for easy fixing on the equipment. Two slide rails 3 are arranged in parallel, and four corner cylinders 4 are distributed on the outside of the slide rails 3, and are diagonally distributed in groups of two. The moving cylinder 5 is arranged at one end of the bottom plate 1 parallel to the slide rails 3. The limit blocks are arranged at both ends of the slide rails 3 as limiters to limit the stroke of the clamping part, including two first limit blocks 9 and two second limit blocks 10. The first limit block 9 is arranged on the side close to the moving cylinder 5, and the second limit block 10 is arranged on the side away from the moving cylinder 5; the first limit block 9 and the second limit block 10 are both provided with waist-shaped screw holes 11, and the first limit block 9 and the second limit block 10 are connected to the bottom plate 1 through the waist-shaped screw holes 11, which is convenient for fine-tuning their relative positions on the bottom plate 1.
[0029] like Figure 3 As shown, the clamping part includes a fixed plate 6, a slider 7, and a casting fixing mechanism. The slider 7 is arranged at the lower end of the fixed plate 6 and is slidably connected to the slide rail 3. The piston of the moving oil cylinder 5 is connected to the fixed plate 6 through the floating connector 8. The casting fixing mechanism is arranged at the upper end of the fixed plate 6, and is used to fix the reducer housing casting 2 to be cut. The casting fixing mechanism includes a clamping oil cylinder 12, a limit rod 13, and a contour support block 14. The upper surface of the contour support block 14 forms several support points according to the shape of the casting, which is used to place the reducer housing casting 2. The clamping oil cylinder 12 cooperates with the contour support block 14 to fix the reducer housing casting 2 in the vertical direction, and the limit rod 13 is used to fix the reducer housing casting 2 in the horizontal direction.
[0030] like Figure 4 As shown, the tooling protection part includes a baffle 15, a connecting block 16, and a support column 17. The baffle 15 is connected to the side of the fixed plate 6 close to the moving cylinder 5 through the connecting block 16 arranged on its side edge. The support column 17 is arranged at the lower end of the baffle 15 and abuts against the bottom plate 1. When the baffle 15 moves with the fixed plate 6, the baffle 15 can cover the top of the moving cylinder 5.
[0031] When the above embodiment is used, the assembled whole sawing tool is first hoisted onto the equipment without tightening the fixing screws on the tool and the equipment. Then, the reducer housing casting 2 to be cut is placed on the corresponding position of the profiling support block 14, and the pressure cylinder 12 is used to automatically press the reducer housing casting 2. Under the cooperation of the pressure cylinder 12, the profiling support block 14 and the limit rod 13, the relative position of the reducer housing casting 2 is fixed. Figure 5As shown, first saw the riser and flow channel on the rear side of the reducer housing casting 2: fine-tune the position of the first limit block 9 on the bottom plate 1 through the waist-shaped screw hole 11 to align the cutter, and then start the motion cylinder 5 to pull the fixed plate 6 to move to the left along the slide rail 3 until the fixed plate 6 stops when it abuts against the first limit block 9; when the clamping part moves linearly, the corner cylinder 4 turns and is parallel to the fixed plate 6. After the clamping part moves, the corner cylinder 4 will be perpendicular to the fixed plate 6 and press the fixed plate 6 downward to prevent it from moving; the saw blade 18 descends to cut off the riser and flow channel on the rear side of the reducer housing casting 2. Figure 6 As shown, after the riser and runner on the front side of the reducer housing casting 2 are sawed, the position of the second limit block 10 on the bottom plate 1 is fine-tuned again through the waist-shaped screw hole 11 to align the back side of the reducer housing casting 2. After the alignment is completed, the fixing screws between the tooling and the equipment are locked, the corner cylinder 4 loosens the fixed plate 6 and rotates parallel to the fixed plate 6, and the moving cylinder 5 pushes the fixed plate 6 to move to the right along the slide rail 3 until the fixed plate 6 abuts against the second limit block 10 and stops; when the clamping part moves linearly, the corner cylinder 4 rotates and is parallel to the fixed plate 6. After the clamping part moves, the corner cylinder 4 will be perpendicular to the fixed plate 6 and press the fixed plate 6 downward to prevent it from moving; the saw blade 18 descends to cut off the riser and runner on the back side of the reducer housing casting 2. After the sawing is completed, the pressing cylinder 12 is opened to pick up and place the reducer housing casting 2. Among them, the baffle 15 can prevent the sawed waste from hitting the moving cylinder 5 and its related connecting parts.
[0032] The above specific implementation methods are only for illustrating the technical concept and structural features of the utility model, and the purpose is to enable relevant persons familiar with this technology to implement them accordingly. However, the above content does not limit the protection scope of the utility model. Any equivalent changes or modifications made based on the spirit of the utility model should fall within the protection scope of the utility model.
