Description

Technical Field

[0001] The invention relates to the field of machine tool processing, and in particular to a magnetic suction type portable special plane processing device for large frame processing. Background Art

[0002] During processing, the posture of the frame also needs to be changed. When processing the vertical surface of the frame, it is necessary to turn the whole frame over in the processing of large frames:

[0003] (1) Comprehensive processing requirements: Large racks have complex structures and many surfaces, holes, and slots need to be processed. When initially placed, some areas are limited by the machine tool travel and interference, making them difficult to process directly. By turning the rack over, the original blind areas can be exposed, such as the mounting base at the bottom of the rack and the reinforcement rib connection on the back, which can be switched to an upward position for easy operation, ensuring that all processing parts can meet the precision standards.

[0004] (2) Ensure uniform stress: Some processing techniques will change the stress distribution of the frame, such as large-area milling and boring. Long-term single-sided processing can easily cause stress to concentrate on one side of the frame, causing deformation. With the flip processing, the subsequent process can act on the other side, balancing the stress, maintaining the overall flatness and straightness, and making the final frame size stable and not easy to twist.

[0005] (3) Improve assembly adaptability: Large racks are often the key framework of large equipment and need to be assembled with many parts later. Turning processing can accurately polish each assembly contact surface, so that the interface flatness meets the requirements, the relative position of the bolt hole and the positioning pin hole is more accurate, and the gap and misalignment during assembly are reduced, ensuring the overall smooth operation of the equipment and reducing vibration and wear.

[0006] At present, in order to complete the turning over of the rack, it is necessary to weld special turning half-axles on the front and rear ends of the rack. Each turning over of the rack requires the cooperation of bridge cranes and gantry cranes for lifting, which is difficult to construct and has certain risks. Therefore, the turning over of the rack is quite difficult, and the lifting points must be accurately planned during operation to prevent the rack from slipping and colliding, and to ensure the safety of personnel and the integrity of the workpiece. At the same time, large racks encounter problems such as high requirements for machine tool equipment installation site and space, complex support requirements for the rack, and the need to turn the rack over when processing the facade.

[0071] Specific implementation method eight: Combination Figure 1 — Fig.14 This embodiment is described as a magnetic suction type portable special plane processing device for large frame processing;

[0072] Working principle:

[0073] The working mode of the X-axis translation mechanism: the X-axis servo motor 11 drives the X-axis planetary reducer 12 to reduce speed, the X-axis planetary reducer 12 drives the X-axis lead screw 14 to rotate through the coupling 14-2, the X-axis lead screw 14 is connected to the X-axis threaded sleeve 17 installed under the slider fixing plate 5, an X-axis slider 16 is installed under the slider fixing plate 5, and the X-axis slider 16 cooperates with the X-axis guide rail 15. Therefore, when the X-axis servo motor 11 is started, the Y-axis translation mechanism 2 above the slider fixing plate 5 will be driven by the above structure to slide horizontally along the direction of the X-axis.

[0074] The working mode of the Y-axis translation mechanism is as follows: the Y-axis servo motor 22 drives the Y-axis planetary reducer 23 to reduce speed, and the end of the output shaft of the Y-axis planetary reducer 23 is connected to the transmission bevel gear pair 24, which drives the Y-axis ball screw 25 to rotate, and the Y-axis threaded sleeve 28 is fixed on the slider fixing plate 5, and the bottom of the base 21 of the Y-axis servo motor 22 is fixedly connected to the Y-axis guide rail 27, and the Y-axis guide rail 27 can slide on the Y-axis slider 26 along the Y-axis direction.

[0075] Therefore, when the Y-axis servo motor 22 is started, the Y-axis guide rail 27 on the Y-axis translation mechanism 2 cooperates with the Y-axis slider 26 to make the Y-axis translation mechanism 2 move horizontally along the Y-axis direction.

[0076] The working mode of the spindle lifting mechanism is as follows: the spindle servo motor 31 drives the spindle planetary reducer 32, and a pulley is installed at the bottom of the spindle planetary reducer 32. The pulley is connected to the top pulley of the cutter disc shaft 35-2 of the spindle mechanism 35 on the other side through the spindle drive synchronous belt 33. Therefore, when the spindle servo motor 31 rotates, the spindle servo motor 31 drives the cutter disc shaft 35-2 to rotate through the spindle drive synchronous belt 33, so that the cutter disc shaft 35-2 in the spindle mechanism 35 drives the cutter disc 6 to rotate.

[0077] The working method of the spindle mechanism when lifting and lowering: the sleeve 35-1 on the spindle mechanism 35 is inserted into the sleeve socket 21-1 at the end of the pedestal 21, the sleeve 35-1 of the spindle mechanism 35 is connected to the lifting platform 34, and a screw bearing seat 21-2 is integrally connected to one side of the pedestal 21, wherein the threaded position of the screw 21-3 near the top position is screwed into the threaded hole 34-1 of the lifting platform 34, and part of the rod surface of the screw 21-3 is arranged in the screw bearing seat 21-2. When the handwheel 21-4 at the top of the screw 21-3 is rotated, the lifting platform 34 will be lifted and lowered, and the bottom of the lifting platform 34 is connected to the spindle mechanism 35. Therefore, when the lifting platform 34 is lifted and lowered, the spindle mechanism 35 is driven to be lifted and lowered, thereby lifting the cutter disc 6 at the bottom of the cutter disc rotating shaft 35-2 on the spindle mechanism 35.
