Problems solved by technology
[0005] The main purpose of the present invention is to provide a double-spindle box structure of a four-spindle machining center to solve the problem that in the prior art, due to a certain cantilever distance between the headstock and the sliding seat, the headstock is prone to insufficient force during the machining process. Stable situation, which affects the problem of machining accuracy

Embodiment 2
[0065] Example 2 as Figure 1 to Figure 12 Shown: The difference from Example 1 is that two signal transmitters are respectively installed on the front spindle and rear spindle on one headstock, and two signal receivers are respectively installed on the opposite front spindle and rear spindle on the other side of the slide seat. When there are at least three signal receivers receiving the signals from the corresponding signal transmitters, the work will proceed normally.
[0066]The difference from the principle of Embodiment 1 is that the corresponding signal transmitter 10 and the signal receiver 11 are at the same height in the initial state, and during the movement of the front main shaft 9 and the rear main shaft 9 to the Z-axis direction, one of the front main shaft seats There are respectively two signal transmitters 10 on one of the rear main shaft seats, and these four signal transmitters 10 can emit signals all the time. The two signal receivers 11 can receive signa...

The invention discloses the technical field of machining equipment, and particularly relates to a double-spindle box structure with a four-spindle machining center. The double-spindle box structure comprises a base, the base is fixedly connected with a standing column, a cross beam crossing the base is arranged on the standing column, a working table reciprocating in the X-axis direction is slidably installed on the base, the working table is located on the lower part of the cross beam, a sliding seat reciprocating in the Y-axis direction is slidably installed on the cross beam, one or more pairs of spindle boxes reciprocating in the Z-axis direction are oppositely arranged on the two sides of the sliding seat, the cross section of the spindle boxes is in a waist circle shape, the spindleboxes are tightly and slidably connected to the sliding seat and thus the distance between the spindle boxes and the sliding seat approaches zero, the spindle boxes comprise a plurality of spindles, and detachable cutters are installed at the bottom ends of the spindles correspondingly. Design of the waist circular spindle boxes is adopted, the size of the spindles from the side face of the sliding seat is decreased, the distance between the end faces of the spindles and the side face of the sliding seat is decreased, it is ensured that stress of workpieces during machining is more stable, theprecision is higher, and the roughness is better.
Description
technical field [0001] The invention relates to the technical field of machining equipment, in particular to a double-spindle box structure of a four-spindle machining center. Background technique [0002] At present, multi-axis CNC machine tools refer to the X, Y, Z direction movement axes and the rotation of the workpiece, etc., and have multiple independent spindles, and each independent spindle has its own independent control system. Each clamping can Multiple workpieces are processed, but these multiple spindles are often arranged on one side, so the workpiece can only be processed on one side, and the machining accuracy cannot be guaranteed. The workpiece can only be roughly processed, and the workpiece cannot be finished. [0003] The spindle box in the existing multi-axis CNC machine tool is one of the important parts of the machine tool, and is also the key to the workpiece processed by the machine tool. Therefore, the structural rationality of the spindle box is o...
