Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to an intelligent multi-channel gantry machining center. Background Art

[0002] Numerical control machine tools play an important role in modern machining. For the machining of large workpieces and workpieces with complex shapes, such as cutting, gantry machining centers are often used. Gantry machining centers have a wide range of applications in industries such as aerospace, mold manufacturing, and automobile manufacturing due to their high precision, large machining range, and high-rigidity structure. However, most of the existing gantry machining centers can only machine one workpiece at a time, resulting in relatively low machining efficiency. Moreover, when the machining spindle fails and needs to be repaired, the gantry machining center cannot be used, greatly reducing the equipment operating rate. At the same time, the chips generated during cutting are generally manually cleaned when changing workpieces, which is time-consuming and laborious and affects the machining efficiency. Summary of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to design an intelligent multi-channel gantry machining center, which can complete the simultaneous machining of multiple workpieces, improve the machining efficiency, and can automatically discharge and collect chips, reducing the time when manual cleaning affects the equipment operation.

[0004] The purpose of the utility model is achieved by the following technical solutions:

[0005] Design an intelligent multi-channel gantry machining center, including a base and a gantry frame erected on the base. The cross beam of the gantry frame is provided with at least two machining spindles and a spindle moving assembly for driving the machining spindles to make reciprocating linear motions along the X-axis direction and the Z-axis direction. A tool changer is correspondingly arranged beside each machining spindle. The base is provided with a machining platform corresponding to each machining spindle and a platform moving assembly for driving the machining platform to make reciprocating linear motions along the Y-axis direction. Chip removal units extending along the Y-axis direction are arranged on both sides below the machining platform.

[0006] The intelligent multi-channel gantry machining center designed in this solution is equipped with at least two machining spindles and corresponding machining platforms. Each machining spindle can be independently programmed and controlled, so multiple different or identical workpieces can be machined simultaneously, improving the machining efficiency. At the same time, through the sensors integrated in the machining center and the advanced numerical control system, the working state can be monitored in real time, and the operator can remotely control and adjust, improving the machining flexibility. The gantry machining center is configured with a tool changer that can store a variety of tools, and the tool change is automatically completed under the control of the numerical control system according to the machining requirements, reducing the tool change time and improving the machining efficiency. Under the intelligent control of the numerical control system, the machining spindle can move freely along the X-axis direction and the Z-axis direction, and the machining platform for placing the workpiece can move freely along the Y-axis direction, so as to realize multi-axis linkage for high-precision machining of the workpiece. To reduce the time when manual chip cleaning affects the operation of the gantry machining center, a number of chip removal units are arranged on the base. The chips generated during the machining process fall into the chip removal units, which can automatically transfer the chips outside the equipment and collect them, effectively reducing the accumulation of chips inside the equipment.

[0007] Further, the spindle moving assembly includes an X-axis moving unit arranged on the crossbeam of the gantry and a Z-axis moving unit arranged on the X-axis moving unit, and the machining spindle is arranged on the Z-axis moving unit.

The X-axis guide rail is two parallel P-class linear rolling guide rails arranged on the crossbeam of the gantry along the X-axis direction. The first sliding seat is fixedly connected to the slider on the guide rail. The first transmission shaft adopts a lead screw, and the first sliding seat is provided with a threaded hole matching the lead screw.

[0012] The Z-axis moving unit also adopts a linear guide rail moving form to achieve high-precision linear motion. The Z-axis guide rail is two parallel P-class linear rolling guide rails disposed on the first sliding seat along the Z-axis direction. The second sliding seat is fixedly connected to the slider on the guide rail. The second transmission shaft adopts a lead screw. The second sliding seat is provided with a threaded hole matching the lead screw. The second driving member drives the lead screw to rotate, thereby driving the second sliding seat to move along the Z-axis guide rail.

[0013] Further, the first sliding seat is provided with a concave receiving cavity, and a bearing support seat is disposed in the receiving cavity. The second transmission shaft is located in the receiving cavity and is rotatably connected to the bearing support seat.

[0014] In order to reduce the weight borne by the X-axis guide rail, rationally utilize space, and reduce the volume of the spindle moving assembly, the first sliding seat adopts a hollow design, that is, the first sliding seat is designed with a concave receiving cavity. The Z-axis guide rail is disposed on the top surface of the side wall of the receiving cavity. The second transmission shaft is disposed in the receiving cavity and is supported by the bearing support seat. Through this design, the weight of the first sliding seat and the volume of the spindle moving assembly after assembly are effectively reduced.

[0017] Further, the chip removal unit includes a chip removal groove disposed on the base, a spiral rod rotatably disposed at the bottom of the chip removal groove, and a fourth driving member disposed at the end of the chip removal groove and drivingly connected to the spiral rod.

[0018] During the machining process of the workpiece, the chips generated fall into the chip removal groove. To enable the chips to be automatically discharged, a screw rod is installed at the bottom of the chip removal groove, and a fourth driving member drives the screw rod to rotate, thereby driving the chips at the bottom of the chip removal groove to move and be automatically discharged outside the equipment; for the chips that do not fall into the chip removal groove, the operator can assist in sweeping the chips into the chip removal groove, thereby reducing the time for manual cleaning.

[0019] Further, an outlet for chips is provided at one end of the chip removal groove opposite to the position of the fourth driving member, and the end of the screw rod extends out of the outlet for chips.

[0020] The screw rod extending out of the outlet for chips can carry the chips out of the chip removal groove. A chip collector is arranged below the outlet for chips, and the chips fall into the collector, and the staff can clean the chip collector regularly.
