Technical Field
[0001] This utility model relates to the field of machining, specifically to a device for machining oblique holes in three-dimensional structural products. Background Technology
[0002] In the machining industry, with increasingly complex and diversified product designs, the demand for machining oblique holes in three-dimensional structural products has increased significantly. For example, motorcycle cylinder heads. However, traditional machining methods face multiple challenges: on the one hand, while high-end multi-axis CNC equipment is comprehensive in function, its purchase and maintenance costs are high, making it unaffordable for small and medium-sized enterprises; on the other hand, machining oblique hole structures in three-dimensional products using ordinary equipment often relies on repeated manual adjustments of fixture and tool angles, or the use of specific fixtures for different oblique hole structures. This leads to low machining efficiency, unstable machining accuracy, and high skill requirements for operators. Therefore, there is an urgent need for a low-cost, simple, and convenient machining device. Summary of the Invention
[0003] To address the aforementioned problems, this utility model provides a device for processing oblique holes in three-dimensional structural products, which is simple to operate, fast to process, and low in cost.

[0006] Preferably, a second limiting plate is fixedly connected to the mounting column, and the second limiting plate is provided with two sensors with a gap between the two sensors so that the pressing cylinder is located in the gap.
[0007] Preferably, the second limiting plate is provided with a sliding groove, and the sensor is installed in the sliding groove so that the sensor can move along the sliding groove.
[0008] Preferably, the processing plate is provided with multiple support blocks.
[0009] Preferably, the rotary cylinder integrates a speed reducer.
[0010] Preferably, bolts are provided on the two limiting blocks respectively, and an extension portion extends from one end of the processing plate, the extension portion being located between the two bolts.
[0011] The advantages of this utility model are:
[0012] 1. Compared with existing high-end CNC machine tools, this utility model has a simple structure, lower manufacturing and maintenance costs, convenient operation, fast processing speed, and high processing accuracy, and can meet the processing of irregular angles of general products.
[0013] 2. When processing different products, this utility model can adjust the bolts on the limit block and the sensor on the second limit plate to make the rotary cylinder rotate to the appropriate processing angle.

[0017] See Figures 1 to 3A device for processing oblique holes in a three-dimensional structure product includes a frame 1. A mounting base 2 is provided on the platform of the frame 1. An inclined mounting surface is provided on the mounting base 2. A rotary cylinder 3 is mounted on the inclined mounting surface. The rotary cylinder 3 integrates a reducer 31. In this embodiment, a rotary cylinder of model HRQ200A is used. By integrating the reducer 31 into the rotary cylinder 3, excessively fast rotation of the rotary cylinder is avoided, its amplitude is reduced, and cylinder life is increased. A processing plate 4 has multiple bolt holes. The processing plate 4 is fixed to the piston rod of the rotary cylinder 3 by bolts. Multiple bolts secure the processing plate 4 to the piston rod of the rotary cylinder 3, ensuring that the processing plate 4 can rotate with the piston rod and will not fall off. At least two positioning pins 41 are provided on the processing plate 4 for product positioning. In this embodiment, two positioning pins 41 are provided to ensure product positioning. The processing plate 4 is provided with multiple support blocks 42. In this embodiment, there are four support blocks 42. The number of support blocks 42 is set according to the product structure. Their function is to support the concave surface of the product, ensure the stability of the product, and prevent it from shaking after being fixed on the processing plate 4, which would reduce the processing accuracy. A clamping cylinder 5 is fixed to one side of the processing plate 4. A pressure block 51 is fixed to the piston rod of the clamping cylinder 5. A bracket 6 is fixedly connected to the frame 1 below the processing plate 4. The bracket 6 is parallel to the mounting inclined plane. Two limiting blocks 61 are provided on the bracket 6. Bolts 62 are respectively provided on the two limiting blocks 61. An extension 43 extends from one end of the processing plate 4. The extension 43 is located between the two bolts 62. Bolts 62 are provided on the limiting blocks 61. By adjusting the extension length of the bolts 62, the rotation angle of the processing plate 4 can be adjusted, thereby adjusting the processing position and angle of the inclined hole of the product. A mounting column 7 is provided on the platform of the frame 1. A first motor 14 is mounted on the mounting column 7 and connected to a lead screw. A motor assembly box 13 is slidably fitted on one side of the mounting column. The motor assembly box 13 is connected to the lead screw and a second motor 8 is fixedly connected to the motor assembly box 13. A machining tool 9 is fixedly connected to the spindle inside the motor assembly box 13, so that the machining tool 9 is located above the machining plate 4. A second limiting plate 10 is fixedly connected to the mounting column 7. Two sensors 11 are provided on the second limiting plate 10, and a gap is provided between the two sensors 11 so that the clamping cylinder 5 is located in the gap. By setting the sensors 11, it is possible to detect whether the clamping cylinder 5 has rotated to the correct position, thereby confirming whether the machining plate 4 has rotated to the correct position, and further confirming whether the product has rotated to the correct position. If the product is detected to have rotated to the correct position, the machining tool 9 will perform oblique hole machining on the product after a delay of a few seconds. The second limiting plate 10 is provided with a sliding groove 12, and the sensor 11 is installed in the sliding groove 12 so that the sensor 11 can move along the sliding groove 12. After the bolt 62 of the limiting block 61 is adjusted in length, the sensor 11 moves in the sliding groove 12 to ensure that the position of the sensor 11 corresponds to the position of the adjusted bolt 62.
[0018] The steps for using this utility model are as follows: First, according to the processing requirements of the product to be processed, adjust the protruding length of the bolt 62 of the limiting block 61, and simultaneously adjust the position of the sensor 11. After adjustment, the product to be processed is installed and positioned on the upper processing plate 4 through the two positioning pins 41 of the processing plate 4, and supported by four support blocks 42 to ensure its stability. Start the processing device, and the clamping cylinder 5 will first clamp the product to be processed through the pressure block 51. Then, the rotary cylinder 3 drives the processing plate 4 to rotate until the extension 43 of the processing plate 4 is limited by the bolt 62 of the limiting block 61. At the same time, the sensor 11 detects that the clamping cylinder 5 has rotated into position as the processing plate 4 rotates. After a few seconds, the first motor... The first motor 14 drives the motor assembly box 13 to move downwards, and the second motor 8 drives the machining tool 9 to rotate, performing oblique hole machining on the product to be processed. After completing one oblique hole machining, the machining tool 9 is retracted, and the rotary cylinder 3 drives the machining plate 4 to rotate again until the extension 43 of the machining plate 4 is limited by the bolt 62 of another limit block 61. The sensor 11 detects that the clamping cylinder 5, which rotates with the machining plate 4, has rotated into place. After a few seconds, the first motor 14 drives the motor assembly box 13 to move downwards, and the second motor 8 drives the machining tool 9 to rotate, performing another oblique hole machining on the product to be processed. After completing all oblique hole machining, the machining tool 9 is retracted, and the clamping cylinder 5 drives the pressure block 51 to move away, so that the product with completed oblique hole machining can be removed.
