Problems solved by technology

Since the rough and fine mechanisms are shared, the finishing is realized by adjusting the cutting amount, rather than by the structure of the machine tool. Due to the shared mechanism, the accuracy of the mechanism is relatively low.

Embodiment 1

[0015] Referring to Fig. 1, in the embodiment, the spindle head 1 has a C-axis function, and the main shaft of the spindle head 2 is also a servo axis, which can be hobbed. The spindle head 3A is a high-speed spindle head capable of fine milling, fine turning milling or grinding; the tool holder 4 is a turret-type turning tool holder, and its components and the saddle combination have two servo axis functions of X and Z. The combination of tool post 5 and bed saddle has four servo axis functions of B, Y, X and Z; the combination of tool post 6 and small gantry has four servo axis functions of A, Y, X and Z, and there are 11 servo control axes in total. Up to 5 servo axes linkage can be realized. In addition to turning, milling, and gear cutting, the three-spindle, double-gantry, double-drive, and five-linkage compound machining center of this embodiment can also perform high-speed fine milling, fine turning and milling, or grinding. The rough and fine feed mechanism of the ma...

Embodiment 2

[0017] Referring to Fig. 1, the difference from Embodiment 1 is that the spindle head 3 adopts a grinding spindle head, so its finishing function is grinding. The machine has a total of 11 servo-controlled axes.

Embodiment 3

[0019] Referring to FIG. 1 , the difference from Embodiment 1 is that the spindle of the spindle head 3A also has the function of a servo axis, so that the machine tool has twelve servo-controlled axes in total.

Abstract

The invention discloses a kind of digital control compound processing centre which has three primary axis heads and three blade brackets to provide double drives, it is made up of turning primary axis head, milling axis head, fine machining primary head, turning blade bracket, milling blade bracket components, straight lade bracket component, saddle, transverse sliding boards, small door bracket component, a bed, the side door bracket component, tail bracket component and blade bank. The fine machining primary head can be changed, it can assemble high speed milling head, grinding head; the primary axis has servo axis function, the other two primary axes is servo axis. The bathe has at least nine servo axes, it can have twenty servo axes at most, it can realize five-axes linked control; the piece can realize turning, milling, boring, drilling and screwing, and high speed milling and so on. The raw and fine process can be separated, in order to upgrades the precise maintaining of bathe.

Description

technical field [0001] The invention relates to a numerically controlled processing machine tool, in particular to a three-spindle, double-gantry, double-drive, and five-link compound machining center. Background technique [0002] The turning-milling compound machining center is a new type of CNC machine tool that has appeared in recent years. The main form of the turning-milling compound center that has appeared so far is composed of two spindle heads, one for turning and one for milling; Together, or two tool holders, one turning tool holder and one milling tool holder; the roughing and finishing share a set of mechanisms; there is also a three-spindle head form, with two turning spindle heads and one milling spindle head, but the rough and finish machining mechanism is still shared. Due to the sharing of rough and fine mechanisms, the finishing is realized by adjusting the cutting amount, rather than guaranteed by the structure of the machine tool. Due to the sharing of...
