Description

Technical Field

[0001] The utility model relates to the field of machining centers, and more specifically, to a gantry machining center. Background Art

[0002] Currently, machining centers are generally divided into gantry machining centers and horizontal machining centers. Gantry machining centers can generally only machine the top surface of workpieces, while horizontal machining centers generally machine the side surfaces of workpieces.

[0003] Taking a standard six-sided cube workpiece as an example, the spindle of a vertical machining center is from top to bottom and is used to machine the top surface of the workpiece, and a horizontal machining center is used to machine the side surfaces of the workpiece. Therefore, after machining one side, the workpiece needs to be re-clamped.

[0004] However, when clamping the workpiece onto the machining center, all positioning references need to be calibrated, and there are certain errors in the calibration. Therefore, clamping the workpiece multiple times will result in a reduction in machining accuracy.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the scope of protection of the present utility model.

[0021] Embodiment:

[0022] A gantry machining center, as Figures 1 - 3As shown in the figure, it includes a base 1, columns 2, and a crossbeam 3. There are two columns 2 symmetrically arranged. Both ends of the columns 2 are respectively connected to the base 1 and the crossbeam 3. Slide mechanisms 4 are arranged in front of both the columns 2 and the crossbeam 3, and head mechanisms 5 are arranged on the slide mechanisms 4. By arranging the head mechanisms 5 in front of the columns 2 and the crossbeam 3, machining of three surfaces can be carried out simultaneously, greatly improving the machining efficiency. A total of 5 surfaces can be machined in one clamping except for the clamping surface.

[0023] On one side of the base 1 close to the crossbeam 3, a turntable mechanism 6 is fixedly arranged. Through the turntable mechanism 6, the effect of driving the workpiece to rotate is achieved, thereby ensuring the effect of machining 5 surfaces.

[0024] At the connection of the column 2 and the slide mechanism 4, a groove 7 for placing the slide mechanism 4 is arranged. By using the groove 7, the center of gravity moves backward after the column 2 and the slide mechanism 4 are connected, avoiding the problem of forward tilt and ensuring the overall stability.

[0025] The column 2 is arranged in an L-shaped structure, and the short side of the L-shaped structure is connected to the base 1. By the L-shaped structure, the contact area between the column 2 and the supporting surface is increased, improving the structural stability.

[0026] The column 2 is arranged in a hollow structure, and a number of ribs 8 are arranged on the inner wall of the column 2. The number of ribs 8 forms a cross structure. By using the ribs 8 and the formed cross structure, the distribution density of the internal ribs 8 is high. Compared with the parallel arrangement strength, it is 25% higher, and the machining is smoother and the stability is strong.

[0027] In front of the column 2, a tool magazine seat 9 is arranged. On the tool magazine seat 9, a disc-type ATC tool magazine 10 for cooperating with the head mechanism 5 of the column 2 is fixedly arranged. On the side wall of the column 2, a disc-type ATC tool magazine 10 for cooperating with the head mechanism 5 of the crossbeam 3 is fixedly arranged. By using the disc-type ATC tool magazine 10, the convenient tool change effect of the head mechanism 5 is ensured.
