Description

Technical Field

[0001] This utility model relates to the field of five-axis machine tool technology, and more specifically to a chip cleaning device for the surface of a workpiece processed by a five-axis linkage machine tool. Background Technology

[0002] Five-axis CNC machine tools, as key equipment in high-end manufacturing, are widely used in aerospace, military, precision instruments, and high-precision medical equipment industries, and have irreplaceable advantages in machining complex curved workpieces. They can perform machining of complex shapes that are difficult for three-axis machine tools to complete, reducing the number of clamping and datum conversions, and significantly improving machining efficiency and accuracy. Their basic structure typically includes three linear motion axes (X, Y, and Z) and rotary axes around axes A and C.

[0003] However, during the machining process of a five-axis CNC machine tool, a large amount of debris is inevitably generated due to the high-speed cutting of the workpiece by the milling cutter. If these debris remain on the surface of the workpiece, they will have many adverse effects on the machining process and machining quality. For example, the debris may come into contact with the cutter head, causing the cutter head to leave marks on the surface of the workpiece, reducing machining accuracy and surface finish. In addition, if the debris enters the transmission device, guide rails and other critical parts of the machine tool, it will aggravate component wear, increase the risk of equipment failure, and shorten the service life of the machine tool. Utility Model Content

[0008] Furthermore, the outer wall of the A-axis turntable is configured as an outer arc-shaped surface, with the center of the outer arc-shaped surface located on the axis of the active rotating shaft. An inner frame is fixedly connected to the inner wall of the A-axis turntable, and the inner wall of the inner frame is configured as an inner arc-shaped surface, with the center of the inner arc-shaped surface located on the axis of the active rotating shaft. The outer arc-shaped surface of the A-axis turntable is in contact with the inner arc-shaped surface of the inner frame.

[0009] Furthermore, the blowing mechanism includes a centrifugal fan, the exhaust end of which is connected to a distribution pipe, and the distribution pipe is internally connected to several air outlet pipes. The several air outlet pipes penetrate to the inner side of the two guide inclined plates, and the suction end of the centrifugal fan is connected to the inside of the collection mechanism through an air inlet pipe.

[0010] Furthermore, the collection mechanism includes a semi-circular shell, a spiral shaft, a motor, and a collection cylinder.

[0019] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] Reference Figure 1 and Figure 2 , 3 This utility model provides a five-axis linkage machine tool surface debris cleaning device, including an A-axis rotary table 1, with an opening at the top of the A-axis rotary table 1, in which a C-axis rotary table assembly 2 is fixedly installed. The top of the C-axis rotary table assembly 2 is used to install the workpiece a. The device includes a housing 3, with swivel holes on both sides of the inner wall of the housing 3. A passive rotating shaft 4 and an active rotating shaft 5 are respectively rotatably sleeved in the two swivel holes. The inner ends of the passive rotating shaft 4 and the active rotating shaft 5 are fixedly installed to the two sides of the A-axis rotary table 1. An air blowing mechanism 7 is provided inside the A-axis rotary table 1. Two guide plates 6 are fixedly connected to the inner wall of the A-axis rotary table 1. A collection mechanism 8 is fixedly connected to the bottom end of the two guide plates 6. The air blowing mechanism 7 is connected to the collection mechanism 8. The air blowing mechanism 7 is used to blow air into the housing 3 and to extract air from the collection mechanism 8.

[0021] When cleaning debris from the workpiece surface, the machine tool's power mechanism drives the active rotating shaft 5 to rotate, causing the A-axis rotary table 1 to flip 180 degrees. The C-axis rotary table assembly 2 is reversed and faces downwards due to the flipping action of the A-axis rotary table 1. At this time, the workpiece a can be located inside the housing 3, while the A-axis rotary table 1 forms a shield at the top of the housing 3, creating a closed space inside the housing 3. Airflow is generated by the blowing mechanism 7. When the airflow passes through the workpiece a, the debris cleaning effect is achieved. The blowing mechanism 7 also draws air into the collection mechanism 8, causing the collection mechanism 8 to draw air from the top, guiding the airflow into the collection mechanism 8. At this time, some debris can enter the collection mechanism 8 for collection under the action of the airflow, and some debris can enter the collection mechanism 8 for collection under the guidance of the two guide plates 6. The housing 3 can be installed on the X-axis table of a five-axis linkage machine tool.

[0022] Reference Figure 3 There are two air blowing mechanisms 7, which are respectively located on the outer side of the two guide plates 6.

[0023] By setting two air blowing mechanisms 7, the amount of airflow inside the A-axis turntable 1 can be increased, improving the debris cleaning effect. On the other hand, the simultaneous output of the two air blowing mechanisms 7 can form a counter-current airflow in the middle, which facilitates the falling of debris.

[0024] Reference Figure 2 The bottom of the A-axis turntable 1 is provided with a cable tray 11 that communicates with the opening. One end of the passive rotating shaft 4 is provided with a shaft hole that extends to the other end and is connected to the cable tray 11. A conductive slip ring is provided in the shaft hole of the passive rotating shaft 4, and the fixed end of the conductive slip ring is connected to the outer wall of the housing 3. This setting facilitates the wiring of the C-axis turntable assembly 2.

[0025] At the same time, avoid the A-axis turntable 1 rotating 180 degrees to avoid affecting the connection of the wires.

[0026] Reference Figure 3 The outer wall of the A-axis turntable 1 is set as an outer arc surface, and the center of the outer arc surface is located on the axis of the active rotating shaft 5. The inner wall of the A-axis turntable 1 is fixedly connected to an inner frame 9, and the inner wall of the inner frame 9 is set as an inner arc surface, and the center of the inner arc surface is located on the axis of the active rotating shaft 5. The outer arc surface of the A-axis turntable 1 is in contact with the inner arc surface of the inner frame 9.

[0027] This setting ensures the sealing of the A-axis turntable 1 to the inside of the housing 3, preventing internal debris from leaking to the outside.

[0028] Reference Figure 4The blowing mechanism 7 includes a centrifugal fan 71. The exhaust end of the centrifugal fan 71 is connected to a diversion pipe 73. The diversion pipe 73 is connected to a number of air outlet pipes 74. The number of air outlet pipes 74 penetrate to the inner side of the two guide inclined plates 6. The suction end of the centrifugal fan 71 is connected to the inside of the collection mechanism 8 through the air inlet pipe 72.

[0029] When the workpiece is inside the housing 3, the workpiece a is located on the inner side of the two guide inclined plates 6. When the air blowing mechanism 7 is in operation, the centrifugal fan 71 runs and draws air into the collection mechanism 8 through the air inlet pipe 72. This allows the collection mechanism 8 to adsorb the debris. The discharged air is discharged between the two guide inclined plates 6 through several air outlet pipes 74, which cleans the debris on the surface of the workpiece a.

[0030] Reference Figure 5 The collection mechanism 8 includes a semi-circular shell 81, a spiral shaft 83, a motor 84, and a collection cylinder 85. A semi-circular filter plate 82 is fixedly connected to the inner wall of the semi-circular shell 81. The side wall of the semi-circular filter plate 82 has a gap with the inner wall of the semi-circular shell 81. The semi-circular shell 81 is fixedly connected to the bottom ends of two guide inclined plates 6. The side wall of the spiral shaft 83 is in contact with the inner wall of the semi-circular filter plate 82. The spiral shaft 83 is rotated and sleeved on the inner wall of the box 3. A through-hole is opened on one side of the box 3, and the collection cylinder 85 is threaded into the through-hole. The collection cylinder 85 is connected to the semi-circular shell 81. The motor 84 is fixedly installed on the other side of the box 3. The output end of the motor 84 passes through the box 3 and is connected to the end face of the spiral shaft 83. A through hole 86 is opened on the side wall of the semi-circular shell 81, which extends to the gap between the semi-circular shell 81 and the semi-circular filter plate 82. The suction end of the air blowing mechanism 7 is connected to the through hole 86.

[0031] During use, the air blowing mechanism 7 draws gas to create a negative pressure at the gap between the semi-circular shell 81 and the semi-circular filter plate 82, thereby adsorbing debris on the inner wall of the semi-circular filter plate 82. The motor 84 drives the spiral shaft 83 to rotate, which can transport the debris on the inner wall of the semi-circular filter plate 82 into the collection cylinder 85. The collection cylinder 85 is detachable due to the connection between it and the box 3, making it easy to clean the debris.
