A novel five-axis machining center with double spindles has the working principle that:
the base is provided with a swing frame, and the swing frame is provided with two rotary turntables A and B. The swing frame drives the rotary table A and the rotary table B to swing around the swing axis simultaneously, and the two rotary tables can rotate in the plane of the rotary tables.
Two sides of the base are respectively provided with a stand column, a Y-axis guide rail is arranged above each stand column, a cross beam is arranged between the Y-axis guide rails on the stand columns on the two sides, and the cross beam can move back and forth along the Y-axis guide rails.

When the machining is carried out, two workpieces are respectively clamped on the rotary table A and the rotary table B, the X-axis screw rod drives the two sliding seats to move left and right simultaneously, the Y-axis screw rod drives the cross beam to move front and back, the two spindle boxes respectively move up and down along the Z-axis guide rail along respective vertical directions, and thus the two spindles can simultaneously machine the two workpieces on the rotary table A and the rotary table B by driving the cutters.
When one direction of the workpiece is processed and other directions need to be processed, all directions of the two workpieces can be processed simultaneously through the swinging of the swing frame (A axis) and the rotation of the rotary table (C axis). Thus, X, Y, Z, A, C five servo axis + two spindle five axis machining center is formed.
More importantly, when the center distance between the two main shafts and the center distance between the two rotary tables have errors, the driving mechanism drives the inner nut to rotate, the position of the whole composite nut on the X-axis screw rod moves, and the position of the push nut on the X-axis screw rod does not change at the moment, so that the effect of adjusting the distance between the composite nut and the push nut is achieved, namely the center distance between the two main shafts is adjusted. The distance adjusting mechanism can correct the error in time and effectively ensure that the two workpieces can reach the required processing precision.
According to the technical scheme, the distance adjusting mechanism can adjust the center distance of the two main shafts, and can effectively ensure that the two workpieces can reach the required machining precision.
