[0002] Gantry machine tool is a common CNC machine tool, also known as gantry machining center. It is a large machine tool controlled by CNC system, suitable for machining large, heavy and complex workpieces. Gantry machine tools usually have the characteristics of high machining accuracy, high efficiency and good stability, and are widely used in aerospace, automobile manufacturing, mold processing and other fields.

[0003] At present, when a gantry machine tool is used to drill holes in a cooling pipe box, since a large number of holes are required to be drilled on the cooling pipe box, and the existing gantry machine tools are all single-spindle processing, the processing efficiency of the cooling pipe box is low. Therefore, we propose a dual-spindle processing gantry machine tool to solve the above problem. Utility Model Content

[0007] As a preferred technical solution of the utility model, a coil is installed inside the chip removal trough, the conveying direction of the coil is toward the circulating water tank, and a protective mesh plate is placed on the upper end of the chip removal trough. The chip removal trough is used to discharge coolant and processed waste chips, and at the same time push the waste chips into the circulating water tank through the coil.

[0008] As a preferred technical solution of the utility model, a second screw rod is installed inside the machine tool body, the second screw rod is threadedly connected to the crossbeam, and a second servo motor is provided at one end of the second screw rod. The second servo motor drives the second screw rod to rotate, thereby driving the crossbeam to move on the machine tool body.

[0011] As a preferred technical solution of the utility model, a circulating water pump is arranged inside the circulating water tank, and a filter is arranged outside the circulating water pump. The cooling water in the machine tool body is circulated through the circulating water pump. At the same time, impurities in the coolant entering the circulating water pump are filtered through the filter.

[0012] The beneficial effects of the utility model are:

[0013] This machine tool is equipped with two sets of slide spindle structures on a single beam. The two spindles can move independently or synchronously. Compared with traditional single-spindle processing, in some specific machining environments, such as drilling processing of cooling pipe boxes, it can improve work efficiency and speed up production rhythm.
