Abstract
Description
Technical Field
[0001] This utility model relates to a side-mounted dual-drive turning and milling composite machining center base, belonging to the field of mechanical technology. Background Technology
[0002] For mill-turn machining centers, the original single-motor C-axis positioning required hydraulic braking, which placed high demands on hydraulic and electrical response speeds. Furthermore, the motor and the base body were not integrated, which placed high demands on the mating surfaces. Additionally, because the II axis was not fully positioned inside the spindle lubrication chamber of the base, gaps appeared at the labyrinth ring of the II axis end cap, which could easily lead to water leakage, causing oil and water mixing and lubricant emulsification. This resulted in a significant decrease in lubrication effect and affected normal operation. Utility Model Content
[0003] To overcome the shortcomings of the existing technology, this utility model provides a side-mounted dual-drive turning and milling composite machining center base. This device improves the rigidity of the base, reduces the mutual contamination between cooling water and lubricating oil, and can effectively remove iron filings.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a side-mounted dual-drive turning and milling composite machining center base, including a base body, a motor mounting seat fixed on the left side of the base body, and a column mounting seat fixed on the rear side of the base body; a circular spindle lubrication cavity is provided inside the base body near the motor mounting seat; a spindle mounting seat is provided on the base body inside the spindle lubrication cavity; and two two-axis mounting positions are provided on the base body on one side of the spindle mounting seat, both of which are located at the inner edge of the spindle lubrication cavity.
[0005] The base body has a front inclined surface on the front side, a right inclined surface on the right side, a rear inclined surface on the rear side, a chip-collecting buffer surface on the left side, and a main inclined surface at the bottom. The front, right, rear, and chip-collecting buffer surfaces are all connected to the main inclined surface.
[0006] Furthermore, the motor mounting base, the base body, and the column mounting base are integrated into one structure.
[0007] Furthermore, the spindle mounting base is located at the center inside the spindle lubrication chamber.
[0008] Furthermore, a column mounting surface is provided on the top of the column mounting base.
[0009] Furthermore, the front inclined plane, the main inclined plane, the right inclined plane, and the rear inclined plane form an inverted pyramidal cavity.
[0010] Furthermore, the two dual-axis mounting positions are symmetrically distributed along the horizontal axis of the main spindle mounting base.
[0011] The beneficial effects of this utility model are as follows: This utility model improves the rigidity of the base, reduces the mutual contamination between cooling water and lubricating oil, effectively removes iron filings, and ensures the normal operation of the equipment; it can install two spindle motors, making the drive more stable; both spindle mounting positions are set inside the spindle lubrication cavity, and the spindle mounting seat is set in the center of the spindle lubrication cavity, avoiding lubricating oil emulsification caused by oil-water mixing; the spindle lubrication cavity is designed as a circle, which is more conducive to processing; the front inclined surface, main inclined surface, right inclined surface and rear inclined surface form an inverted pyramidal chip removal cavity, and the iron filings can automatically fall into the chip conveyor for discharge.

[0017] like Figure 1 As shown in Figure 2, a side-mounted dual-drive milling and turning composite machining center base includes a base body 11. A motor mounting seat 1 is fixed to the left side of the base body 11, and a column mounting seat 12 is fixed to the rear side of the base body 11. A column mounting surface 4 is provided on the top of the column mounting seat 12. The motor mounting seat 1, the base body 11, and the column mounting seat 12 are integrally formed. At the end near the motor mounting seat 1, a circular spindle lubrication cavity 10 is provided inside the base body 11. Inside the spindle lubrication cavity 10, a spindle mounting seat 3 is provided on the base body 11, and the spindle mounting seat 3 is located at the center of the spindle lubrication cavity 10. On one side of the spindle mounting seat 3, two dual-axis mounting positions 2 are provided on the base body 11. Both dual-axis mounting positions 2 are located at the inner edge of the spindle lubrication cavity 10, and the two dual-axis mounting positions 2 are symmetrically distributed along the horizontal axis of the spindle mounting seat 3.
[0018] A front inclined surface 5 is provided on the front side of the interior of the base body 11, a right inclined surface 7 is provided on the right side of the interior of the base body 11, a rear inclined surface 8 is provided on the rear side of the interior of the base body 11, a chip-collecting buffer surface 9 is provided on the left side of the interior of the base body 11, and a main inclined surface 6 is provided at the bottom of the interior of the base body 11. The front inclined surface 5, the right inclined surface 7, the rear inclined surface 8 and the chip-collecting buffer surface 9 are all connected to the main inclined surface 6. The front inclined surface 5, the main inclined surface 6, the right inclined surface 7 and the rear inclined surface 8 form an inverted pyramidal cavity.
[0019] The motor mounting base 1 and the base body 11 are designed as an integral structure, which has stronger structural rigidity and can reduce adjustment errors. The two-axis mounting position 2 is designed inside the spindle lubrication cavity 10, making the spindle lubrication cavity 10 structurally complete and reducing the mutual contamination between cooling water and lubricating oil. The spindle mounting base 3 is set at the center of the spindle lubrication cavity 10, and the spindle lubrication cavity 10 is designed as a circle, which is more conducive to processing. The front inclined surface 5, the main inclined surface 6, the right inclined surface 7, and the rear inclined surface 8 form an inverted pyramidal chip removal system. Since the slope of the main inclined surface 6 is relatively small, a chip receiving buffer surface 9 is added to increase the slope of the main inclined surface 6. The iron chips accumulated on the chip receiving buffer surface 9 can be washed to the main inclined surface 6 through cooling, and then discharged through the chip conveyor. The column mounting surface 4 is set above the chip removal channel, and the chips can be discharged directly from the rear of the base body 1 through the chip conveyor.
[0020] The drive motor is changed from one to two and is placed on the left side of the base body 1. The two shafts are symmetrically distributed along the horizontal axis. The motor mounting base 1 and the base body 11 are integrated and have high strength. The base body 1 can also share the motor vibration. The two shaft mounting positions 2 are set in two places and are both set in the spindle lubrication cavity 10 and symmetrically distributed along the horizontal axis of the spindle mounting base 3. The symmetrical distribution makes the transmission distance the same.
[0021] The front inclined surface 5, the main inclined surface 6, the right inclined surface 7, and the rear inclined surface 8 together form an inverted pyramidal structure. Iron filings falling on the inclined surface can automatically roll down to the chip discharge port at the bottom of the slope. In addition, since the top of the main inclined surface 6 is far from the chip discharge port, a chip receiving buffer surface 9 is set at the top of the slope to increase the slope of the main inclined surface 6. The column mounting surface 4 is located above the chip discharge channel on the rear side of the spindle lubrication cavity 10, saving space for chip discharge.
