Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-6, a rigid reinforcing structure for a gantry frame of a milling machine comprises a frame made of a material with a low thermal expansion coefficient, wherein the frame comprises a base 1 and a frame 2 mounted on the base 1, the frame 2 is in an Jiong-shaped structure, the frame 2 can be integrally formed with the base 1, or the frame 2 can be mounted on the base 1 through bolts, and a noise reduction structure is arranged on the frame 2; the structure of making an uproar of falling can be a plurality of holes 3 of making an uproar of falling that set up on frame 2, and it can absorb some noise to fall hole 3 of making an uproar, simultaneously fall the structure of making an uproar still set up a plurality of cavitys 4 inside frame 2, and a plurality of cavitys 4 can constitute honeycomb, and the noise can effectively be absorbed by a plurality of cavitys 4 inside frame 2 when passing frame 2, reduces the noise by a wide margin, and noise pollution abatement.

In the embodiment, the low thermal expansion coefficient material is granite, olivine, gneiss or marble, and the granite is preferably adopted, so that the stress of the granite is small, the granite is not easy to deform, and meanwhile, the thermal expansion coefficient is small and is slightly influenced by the environmental temperature; meanwhile, the density of granite is smaller than that of iron, and the overall weight is lighter; the granite has dense holes inside, a honeycomb structure can be formed, and good shock absorption and sound absorption effects are achieved; other materials are used to create cavities within the frame 2.

Further, as shown in fig. 4-6, an X-axis linear module 5 is mounted on a cross beam of the frame 2, a Z-axis linear module 6 is mounted on the X-axis linear module 5, and a milling assembly 7 is mounted on the Z-axis linear module 6; and a Y-axis linear module 8 is mounted on the base 1. Milling subassembly 7 includes milling cutter, driving motor, blade holder, driving motor installs on Z axle straight line module 6, and blade holder direct mount is on driving motor's drive end, and milling cutter inserts again and establishes on the blade holder, by driving motor direct drive milling cutter rotation, transmission loss can not appear between the two, has advantages such as machining precision height, production efficiency height and cell body processing smooth finish height.
