The invention relates to the technical field of mechanical equipment, in particular to a multi-purpose machine tool with a single-sided double head.

Conventional cutting machine tools for cutting, grinding or special machining methods to further machine various metal workpieces to achieve the required geometry, dimensional accuracy and surface quality; as in the first and 2 shows a base 1 , a beam 2 fixed to the base 1 , a slide mounted on the beam 2 (not labeled), and a cutting mounted on the slide. a head 3, and the cutting head 3 is provided with a spindle 4 for mounting a cutter such as a milling cutter, and the base 1 under the spindle 4 is provided with a movable table 5; wherein the sliding seat is Actually mounted on a first line rail 6 and a second line rail 7 on the side of the beam 2, and connected to a transmission screw (not shown), wherein the transmission screw is driven by a servo motor; The sliding seat can be displaced by the transmission of the driving screw and the displacement of the combined line of the first line rail 6 and the second line rail 7.

The machine tool mentioned above is easy to assemble, and can also meet the requirements of the metal device with relatively simple processing technology; however, since the cutting head 3 and the sliding seat are relatively heavy, and the machining process also generates a large Torque and other factors, at this time, it is necessary to rely on the two rails 6, 7 to bear at the same time, wherein the displacement of the sliding seat needs to bear part of the downward pressure, the backward pressure and the heavy cutting process The torque generated by the main shaft 4, etc., will gradually cause fatigue damage to the components such as the second rails 6, 7 and the cross member 2, thereby indirectly affecting the rigidity, accuracy, and service life of the machine.

In addition, in the process of precision molds or workpieces, because the cutting tool has different requirements on the rotational speed and the torsion, the conventional cutting machine has only a single-form cutting mode, in short, before the low speed. After the rough machining process is performed on the high-torque heavy-cut roughing machine, the fine machining process is continued to be converted to a high-speed, low-torque fine processing machine, so that the mold or workpiece must be at least twice separately. The installation, loading, positioning, etc., it is necessary to carry out repeated disassembly and assembly, correction of workpieces and other cumbersome processes, such as increasing the number of processes and their working hours, and even more, at least two or more devices are required to be indirectly added.
