Description

Technical Field

[0001] This utility model relates to the field of die casting processing, specifically to a positioning and cutting device for aluminum alloy die castings. Background Technology

[0002] Aluminum alloy die castings are widely used in numerous industrial fields such as automotive, aerospace, and electronic equipment due to their excellent properties such as light weight, high strength, and corrosion resistance. As these industries continuously increase their requirements for product performance and precision, the processing technology of aluminum alloy die castings faces even greater challenges. In the processing of aluminum alloy die castings, cutting is one of the key steps, aiming to further adjust the dimensional accuracy and improve the surface quality of the die castings. However, traditional cutting devices for aluminum alloy die castings have many shortcomings and cannot meet the demands of modern industrial production for efficient and high-precision machining. For example, aluminum alloy die castings are very diverse, but traditional positioning and clamping methods are relatively simple. When dealing with complex aluminum alloy die castings, clamping can only be performed in relatively flat areas, resulting in uneven clamping forces. During the cutting process, due to unstable or uneven clamping forces, the die casting may vibrate or loosen, affecting not only the cutting quality but also potentially damaging the tool, increasing production costs, and consequently impacting the stability and safety of production. Utility Model Content

[0003] To solve the above-mentioned technical problems, a positioning and cutting device for aluminum alloy die castings is provided. This technical solution addresses the issue that the traditional positioning and clamping methods mentioned in the background technology are relatively simple in structure. When dealing with complex aluminum alloy die castings, they can only be clamped and fixed in some relatively flat areas. During the cutting process, due to unstable or uneven clamping force, the die castings may vibrate or loosen, which not only affects the cutting quality but may also damage the tool, increase production costs, and consequently affect the stability and safety of production.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A positioning and cutting device for aluminum alloy die-casting parts includes an integrated box. Symmetrically slidable base plates are arranged on the upper end of the integrated box. Locking studs with the same diameter and parallel to each other are fixedly connected to both ends of the base plates. Clamping plates are fitted onto the surfaces of the locking studs. The surfaces of the clamping plates have evenly distributed through holes. Mounting shells are fixedly connected to the inner sides of the through holes. Compression springs are fixedly connected to the inner sides of the mounting shells. A rubber pad with the same diameter as the compression spring is fixedly connected to the other end of the compression spring. The locking studs fixedly connected to both ends of the base plates and the clamping plates fitted onto their surfaces enable initial clamping of the aluminum alloy die-casting parts. The mounting shells and compression springs fixedly connected to the inner sides of the evenly distributed through holes on the clamping plates, as well as the rubber pad connected to the other end of the compression spring, further enhance the stability and reliability of the clamping. The clamping springs provide continuous clamping force, while the rubber pads increase friction, preventing displacement of the die-casting during cutting and avoiding scratches on the die-casting surface. This ensures the stability of the cutting process and the integrity of the die-casting. Furthermore, due to the several pairs of clamping springs on the clamping plate, even with different structures in the clamping area, the compression of the springs allows the clamping plate to better fix the die-casting, increasing the adaptability of the device to die-castings of different shapes. The base plates can slide relative to each other, allowing the device to adapt to aluminum alloy die-castings of different sizes and shapes. A bridge plate fixedly connected to the lower end of the base plate is threaded to a second adjusting screw via a threaded hole. One end of the second adjusting screw is connected to an adjusting handle, allowing the operator to easily adjust the position of the base plate, thereby achieving precise positioning of the aluminum alloy die-casting in different directions, meeting different processing requirements, and improving the flexibility of the device.

[0006] Preferably, hydraulic lifting columns are fixedly installed at the four corners of the upper surface of the integrated box, and a cross brace frame is fixedly connected to one end of the hydraulic lifting column. An adjusting slider that can move along its center line is slidably connected to the inner side of the cross brace frame.

[0007] Preferably, a first adjusting screw that can rotate around its center line is installed on one side of the adjusting slider. The surface of the first adjusting screw is threadedly connected to a motor base that can slide left and right along its surface. A drive motor is fixedly installed at the lower end of the motor base, and a tool holder for mounting a cutting tool is fixedly installed at the output end of the drive motor.

[0008] Preferably, a bridging plate is fixedly connected to the lower end of the substrate, and a threaded hole is provided at one end of the bridging plate. A second adjusting screw is threadedly connected to the inner side of the threaded hole, and an adjusting handle is fixedly connected to one end of the second adjusting screw.

[0009] Preferably, a first servo motor is fixedly mounted on the outer surface of one of the adjustment sliders.

[0010] Preferably, a second servo motor is fixedly installed at one end of the cross brace frame, and a horizontal adjustment rod is splinedly connected to the output end of the second servo motor.

[0011] Compared with existing technologies, this utility model provides a positioning and cutting device for aluminum alloy die castings, which has the following advantages: This solution includes an integrated box, a base plate, locking studs, clamping plates, a mounting shell, a compression spring, and rubber pads. Through the fixed connection between the base plate and the locking studs, and the clamping plates fitted onto the surface of the locking studs, the mounting shell is fixed inside the through-holes, and the compression spring connects the mounting shell and the rubber pads. The locking studs fixedly connected to both ends of the base plate and the clamping plates fitted onto its surface enable initial clamping of the aluminum alloy die castings. The mounting shells and compression springs fixedly connected to the inside of the through-holes evenly distributed on the clamping plates, and the rubber pads connected to the other end of the compression springs, further enhance the stability and reliability of the clamping. The clamping springs provide continuous clamping force, while the rubber pads increase friction, preventing displacement of the die-casting part during cutting and avoiding scratches on its surface. This ensures the stability of the cutting process and the integrity of the die-casting part. Furthermore, due to the several pairs of clamping springs on the clamping plates, even with different structures in the clamping area, the contraction of the springs allows the clamping plates to better fix the die-casting part, increasing the adaptability of this device to die-casting parts of different shapes.

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] See Figures 1 to 4 This utility model provides a technical solution: a positioning and cutting device for aluminum alloy die castings, comprising an integrated box 1. The integrated box 1 has symmetrically arranged sliding base plates 2 at its upper end. Both ends of the base plates 2 are fixedly connected to locking studs 3, which have the same diameter and are parallel to each other. A clamping plate 4 is fitted onto the surface of each locking stud 3. The clamping plate 4 has evenly arranged through holes on its surface. A mounting shell 5 is fixedly connected to the inner side of each through hole. A compression spring 6 is fixedly connected to the inner side of the mounting shell 5. A rubber pad 7 with the same diameter is fixedly connected to the other end of the compression spring 6. This design allows the base plates 2 to be flexibly adjusted according to the size and shape of the aluminum alloy die casting. The symmetrical arrangement and the fixed connection of the locking studs 3 ensure the stability of the base plates 2. The through hole on the clamping plate 4, the clamping spring 6 inside the mounting shell 5, and the rubber pad 7 work together to achieve stable clamping of the die casting. This allows the operator to choose the clamping area more freely when clamping the die casting. Even if there are some uneven areas on the die casting, it can be compensated to a certain extent, reducing the displacement or vibration of the die casting during the cutting process, thereby ensuring cutting accuracy and processing quality. At the same time, the rubber pad 7 can also prevent scratches on the surface of the die casting, protecting the appearance quality of the die casting.

[0019] Furthermore, hydraulic lifting columns 8 are fixedly installed at the four corners of the upper surface of the integrated box 1. One end of the hydraulic lifting column 8 is fixedly connected to a cross brace frame 9. An adjusting slider 10 that can move along its center line is slidably connected to the inner side of the cross brace frame 9. The hydraulic lifting column 8 provides stable support and power transmission for the entire device. The height of the cross brace frame 9 can be easily adjusted through the hydraulic system to accommodate die-cast parts of different sizes. The adjusting slider 10 that is slidably connected to the inner side of the cross brace frame 9 can move along its center line, which allows the position of the cutting tool to be precisely adjusted, ensuring that the tool can be accurately aligned with the processing part of the die-cast part, thus improving the flexibility and accuracy of the processing.

[0020] Furthermore, a first adjusting screw 11, rotatable around its centerline, is mounted on one side of the adjusting slider 10. A motor mount 12, capable of sliding left and right along its surface, is threaded onto the surface of the first adjusting screw 11. A drive motor 13 is fixedly mounted at the lower end of the motor mount 12, and a tool holder 14 for mounting cutting tools is fixedly mounted at the output end of the drive motor 13. The design of the first adjusting screw 11 allows the motor mount 12 to slide left and right along its surface, thereby enabling fine-tuning of the cutting tool position. The drive motor 13 provides power to the cutting tool, and the cutting position of the tool can be easily adjusted by sliding the motor mount 12 to meet different machining requirements.

[0021] Furthermore, a bridging plate 15 is fixedly connected to the lower end of the substrate 2. One end of the bridging plate 15 has a threaded hole, and a second adjusting screw 16 is threadedly connected to the inner side of the threaded hole. An adjusting handle 17 is fixedly connected to one end of the second adjusting screw 16. The second adjusting screw 16 is a bidirectional threaded screw, meaning that left-hand and right-hand threads are machined at both ends, and it is fitted with two corresponding reverse nuts. When the screw rotates, the two nuts move synchronously in opposite directions along the axial direction due to the opposite thread directions, thereby causing the two connected bridging plates 15 to move closer or further apart synchronously. The bridging plate 15 creates a stable connection structure between the substrate 2 and the second adjusting screw 16. The second adjusting screw 16 can be easily rotated using the adjusting handle 17 to adjust the position of the substrate 2, achieving precise positioning of the die-cast part. This manual adjustment method is simple and easy to use, allowing operators to quickly adjust according to the size and shape of the die-cast part, improving the applicability and flexibility of the device.

[0022] Furthermore, a first servo motor 18 is fixedly mounted on the outer surface of one of the adjusting sliders 10. A servo motor is a type of motor that can precisely control position, speed, and torque. It can be precisely controlled according to preset programs and parameters to ensure that the adjusting slider 10 maintains stable speed and position accuracy during movement. This not only improves the accuracy of cutting and machining but also reduces human error, lowers labor intensity, and improves production efficiency.

[0023] Furthermore, a second servo motor 19 is fixedly installed at one end of the cross brace frame 9. The output end of the second servo motor 18 is splinedly connected to a transverse adjustment rod 20. The second servo motor 19 can control the rotation of the transverse adjustment rod 20 to convert the circular motion of the transverse adjustment rod 20 into the linear motion of the adjustment slider 10, thereby realizing the position adjustment of the cutting tool. This design makes the adjustment of the cutting tool in the transverse direction more flexible and precise, and can better adapt to the processing needs of die-cast parts of different shapes and sizes, improving the overall performance and processing accuracy of the device.

[0024] This solution includes the following work process:

[0025] Inspection of the device: Before use, a comprehensive inspection of the entire device should be carried out, including the integrated box 1, base plate 2, locking studs 3, clamping plate 4, mounting shell 5, compression spring 6, rubber pad 7, hydraulic lifting column 8, cross brace frame 9, adjusting slider 10, first adjusting screw 11, motor base 12, drive motor 13, tool holder 14, bridge plate 15, second adjusting screw 16, adjusting handle 17, first servo motor 18 and second servo motor 19, etc., to ensure that all components are intact, firmly connected, and free from any looseness, wear or other abnormalities.

[0026] Prepare the cutting tools: Select appropriate cutting tools according to the machining requirements of the aluminum alloy die castings and install them on the tool holder 14. During installation, refer to the tool installation guide to ensure that the tools are installed firmly and accurately.

[0027] Placement of die casting: Place the two ends of the aluminum alloy die casting to be processed between the two clamping plates 4. Adjust the position of the base plate 2 according to the shape and size of the die casting so that the die casting is in a suitable position.

[0028] Clamping the die-casting: The die-casting is clamped using locking studs 3 and clamping plates 4. Specifically, clamping plates 4 are fitted onto locking studs 3, aligning the through holes on clamping plates 4 with the corresponding positions on the die-casting. Then, the locking nuts on locking studs 3 apply pressure to the two clamping plates 4, which in turn causes the compression springs 6 and rubber pads 7 to apply pressure to the die-casting, thus achieving stable clamping. The compression springs 6 have different compression distances depending on the surface of the die-casting, allowing the device to clamp the die-casting more effectively.

[0029] Adjusting slider 10: According to the processing requirements, the height of the cross brace frame 9 is adjusted by the hydraulic lifting column 8. The adjusting slider 10 can move along the center line of the cross brace frame 9, thereby realizing the position adjustment of the cutting tool in the front and rear directions.

[0030] Adjusting the motor mount 12: Rotate the first adjusting screw 11 to make the motor mount 12 slide left and right along the surface of the first adjusting screw 11, thereby adjusting the position of the drive motor 13 and the tool holder 14, and realizing the position adjustment of the cutting tool in the left and right direction. By precisely adjusting the position of the motor mount 12, it can be ensured that the cutting tool is accurately aligned with the machining part of the die casting, thus improving machining accuracy.

[0031] Start drive motor 13: After completing the above adjustments, start drive motor 13. The output end of drive motor 13 drives tool holder 14 and cutting tool to rotate, and begins to cut aluminum alloy die castings.

[0032] Monitoring the machining process: During the cutting process, the operator should closely monitor the machining situation, observe the cutting effect of the cutting tool, the clamping status of the die casting, etc. If any abnormality occurs, the machining should be stopped in time for adjustment.

[0033] Stop machining: After the cutting of the aluminum alloy die casting is completed, stop the operation of the drive motor 13 to stop the cutting tool from rotating.

[0034] Remove the die casting: Loosen the clamping plate 4 to release the clamping of the die casting, and then remove the finished die casting from the base plate 2.

[0035] Cleaning the device: Clean the device, including removing chips and wiping the surfaces of each component, to keep the device clean for the next use.
