[0033] Meanwhile, the inner and outer moving mechanism 6 is installed below the bearing seat 2 on the support base 1, and the moving axes of the horizontal moving mechanism 3, the longitudinal moving mechanism 4 and the inner and outer moving mechanism 6 are all perpendicular to each other in space. The single-arm rotary table 7 is installed on the inner and outer moving mechanism 6, and the single-arm rotary table 7 is used for installing the workpiece clamping fixture. The single-arm rotary table 7 can be optimized and improved according to the specific design requirements, mainly in that the workpiece clamping fixture can be rotated and adjusted in two dimensions perpendicular to each other on the rotary axis, that is, around the C-axis and around the B-axis. Generally, the rotation around the B-axis is swinging rotation. At the same time, the single-arm rotary table 7 is moved forward and backward by the inner and outer moving mechanism 6, that is, in the Z-axis direction. Thus, the workpiece can be moved in the Z-axis direction, swung around the B-axis, and rotated around the C-axis. The tool can be moved in the X-axis and Y-axis directions, and the workpiece can be dynamically processed in five dimensions. The complex surface and complex structure can be realized.

[0034] Meanwhile, the D-shaped tool magazine 8 is installed on one side of the bearing seat 2 for tool replacement during the workpiece processing according to the processing requirements. After the linkage processing machine is moved to the position of the D-shaped tool magazine 8 in the X-axis and Y-axis directions, the tool holder is rotated out by the D-shaped tool magazine 8 to realize the automatic tool changing process.

[0035] The action mechanism for processing the complex structure and complex surface of the workpiece is integrated, the implementation principle is displayed, and the actual operation can be performed to meet the practical training requirements. The support base 1 can realize the support and installation of the entire five-axis linkage processing machine, and the height of the specific processing operation can be adjusted by the height of the support base 1.

[0036] Of course, it can also be used in actual processing scenes.

[0037] Specifically, the inner and outer moving mechanism 6 comprises first sliding rails 61 which are spaced apart and mounted on the support base 1, first sliding seats 62 are mounted on the two first sliding rails 61, a first driving mechanism 63 is mounted on the support base 1 and used to drive the first sliding seats 62 to move reciprocatingly, and the single-arm rotating table 7 is mounted on the first sliding seats 62. The first sliding seats 62 are driven by the first driving mechanism 63 to move relative to the support base 1 in the Z-axis direction, so as to realize the movement displacement adjustment of the single-arm rotating table 7 in the Z-axis direction.

[0038] Meanwhile, since the inner and outer moving mechanism 6 is located below the machining position, the machining generated debris will cause interference. Therefore, a protective cover 64 is mounted on the first sliding seats 62 and used to cover the inner and outer moving mechanism 6, and a protective shell 65 is located on the outward moving side. The protective cover 64 is used to block the debris, and the protective shell 65 is used to protect the front side. Meanwhile, the protective shell 65 is provided with inclined flow guide surfaces on both sides, which are used to guide the debris to the support base 1 and then collect and discharge the debris. Meanwhile, the bearing seat 2 is provided with a baffle 9 which is clamped on the protective cover 64. The baffle 9 is used to avoid the debris from splashing to the rear of the bearing seat 2.

[0039] Specifically, the transverse moving mechanism 3 comprises second sliding rails 31 which are spaced apart and mounted on the bearing seat 2, and the longitudinal moving mechanism 4 is mounted on the two second sliding rails 31. A second driving mechanism 32 is mounted on the bearing seat 2 and used to drive the longitudinal moving mechanism 4 to move reciprocatingly. The second driving mechanism 32 is used to realize the movement of the entire longitudinal moving mechanism 4 in the X-axis direction. The longitudinal moving mechanism 4 comprises a second sliding seat 41 which is mounted on the second sliding rails 31. The second sliding seat 41 is provided with third sliding rails 42 which are spaced apart and mounted thereon. Third sliding seats 43 are mounted on the two third sliding rails 42. The second sliding seat 41 is provided with a third driving mechanism 47 which is used to drive the third sliding seats 43 to move reciprocatingly. The third driving mechanism 47 is used to realize the movement of the third sliding seats 43 relative to the second sliding seat 41 in the Y-axis direction, so as to realize the position movement adjustment of the tool in the X-axis and Y-axis directions. The third sliding seats 43 are provided with clamping seats 44. The clamping seats 44 are provided with mounting stepped holes 45 which are used to mount the machining linkage machine 5. The clamping seats 44 are provided with adjusting openings 46 which are in communication with the mounting stepped holes 45. The clamping seats 44 are provided with fasteners which are used to adjust the size of the adjusting openings 46.

[0040] Specifically, the first driving mechanism 63, the second driving mechanism 32 and the third driving mechanism 47 are all screw driving mechanisms, comprising two rotating seats 10 installed at intervals, two driving screws 11 rotatably installed on the two rotating seats 10, and a nut 12 threadedly connected to the driving screw 11 and used for connecting the first sliding seat 62 or the second sliding seat 41 or the third sliding seat 43; one end of the driving screw 11 is connected with a first speed reducer, and the first speed reducer is connected with a first driving motor 13. Since the first sliding seat 62, the second sliding seat 41 and the third sliding seat 43 are limited to relative sliding, the nut 12 is threadedly connected with the driving screw 11 after being connected, and the reciprocating position adjustment is realized by rotating the driving screw 11 driven by the first driving motor 13.

[0041] Of course, other driving mechanisms can also be used, such as gear and rack cooperation mechanisms or various forms of telescopic cylinders.

[0042] The single-arm rotary table 7 is used to realize the workpiece swing around the B axis and the workpiece rotation around the C axis, and the single-arm rotary table 7 comprises a mounting seat 71 mounted on the first sliding seat 62, a first rotating disc 72 rotatably mounted on the mounting seat 71, a first rotating cylinder 73 mounted on the first rotating disc 72, a connecting arm 74 mounted on the first rotating cylinder 73, a mounting shell provided on the connecting arm 74, a second rotating disc 75 rotatably mounted on the mounting shell, a second rotating cylinder 76 mounted on the second rotating disc 75, and a tool clamp mounted on the second rotating cylinder 76. A second driving motor 77 is connected to the first rotating disc 72, and a third driving motor 78 is connected to the second rotating disc 75. The rotating axis of the first rotating cylinder 73 is parallel to the moving axis of the inner-outer moving mechanism 6, and the rotating axis of the second rotating cylinder 76 is parallel to the moving axis of the longitudinal moving mechanism 4. The first rotating disc 72 swing angle adjustment and the second rotating disc 75 rotation angle adjustment are realized by the independent second driving motor 77 and the third driving motor 78, so as to complete the spatial angle adjustment of the workpiece.

[0043] Meanwhile, the tool will be replaced according to the corresponding machining requirements during the machining process, and the height parameter of the replaced tool needs to be compensated to meet the reference alignment during the workpiece machining. Therefore, a tool height detection sensor 79 is mounted on the connecting arm 74, and the height compensation parameter is generated by the tool touching the tool height detection sensor 79 after the tool is replaced. The tool height detection sensor 79 can be a mature sensor such as a position switch or a pressure sensor.

[0044] Specifically, the D-shaped tool magazine 8 can automatically rotate the internal tool out and cooperate with the linkage machining machine to realize automatic tool replacement. The D-shaped tool magazine 8 comprises a mounting frame 81 mounted on the bearing seat, a bearing plate 82 mounted on the mounting frame 81, a second speed reducer 83 mounted on the bearing plate 82, a connecting cylinder 84 mounted on the second speed reducer 83, and a D-shaped tool disc 85 mounted on the connecting cylinder 84. A dustproof shell 87 is fixed on the bearing plate 82 and covers the D-shaped tool disc 85. The dustproof shell 87 has an opening. A dustproof plate 86 is mounted on the D-shaped tool disc 85 and is perpendicular to the bearing plate 82. The dustproof plate 86 is used to cover the opening of the dustproof shell 87. The height of the dustproof plate 86 is less than the height of the inner wall of the dustproof shell 87. A fourth driving motor 88 is mounted on the second speed reducer 83 and is below the bearing plate 82. The fourth driving motor 88 drives the connecting cylinder 84 and the D-shaped tool disc 85 to rotate. A tool holder is arranged on the D-shaped tool disc 85 to clamp the tool. When the tool is rotated out, the dustproof plate 86 rotates into the dustproof shell 87. After the tool is replaced, the D-shaped tool disc 85 is rotated to rotate the tool into the dustproof shell 87. The dustproof plate 86 rotates to the opening to protect the internal tool and prevent the waste from splashing into the internal tool.

[0045] When the D-shaped tool magazine 8 is installed, the rotation flatness and position of the D-shaped tool disc 85 should meet the requirements of the tool replacement and grabbing position. Specifically, a first right-angle block 89 is arranged on the mounting frame 81 to position the mounting angle of the bearing plate 82. A second right-angle block 810 is arranged on the mounting frame 81 to position the mounting angle of the end of the mounting frame 81. The first right-angle block 89 positions the mounting angle of the bearing plate 82 relative to the mounting frame 81. The second right-angle block 810 positions the mounting angle of the mounting frame 81 mounted on the bearing seat 2 to ensure the stability of the D-shaped tool disc 85 in the rotating state and meet the accuracy of the tool replacement position.

[0046] Specifically, waste water and waste will be generated during the machining process and need to be collected and treated. Therefore, a groove 101 is arranged on the support base 1. A flow guide opening 102 is arranged on the bottom surface of the groove 101. The bottom surface of the groove 101 is inclined towards the flow guide opening 102. A water storage tank is arranged in the support base 1 and connected to the flow guide opening 102.
