Multi-head high-efficiency machining center

Abstract

The invention discloses a multi-head high-efficiency machining center, wherein the machine tool adopts a gantry structure (1), a cross beam linear guide rail (21) is arranged on the gantry frame crossbeam (2), at least three X-axis moving platforms (3) are arranged on the cross beam linear guide rails (21), the X-axis moving platform (3) moves left and right along the cross beam linear guide rail(21); each X-axis moving platform (3) is respectively provided with a Z-axis moving platform (4), and each Z-axis moving platform (4) is respectively provided with a machining spindle (6) for machining; a processing platform (7) is arranged on the Y-axis moving platform (5), the processing platform (7) is arranged below the cross beam of the gantry frame, and the processing platform (7) is a shared platform; the X-axis moving platform (3) and the Z-axis moving platform (4) are driven by a linear motor; the Z-axis moving platform (4) is provided with a balancing device (9) for balancing the self-weight of the Z-axis moving platform. The distribution structure of the multi-head mechanism is simplified, a linear guide rail on the cross beam is shared, and by means of the method, the structure of easily realized and unified head is achieved.

Description

technical field [0001] The invention relates to machining equipment for composite materials such as metal, glass and ceramics. Background technique [0002] Due to the current conventional machining centers on the market, only one head or advanced ones can only process with two heads at the same time. Due to the use of the traditional servo + screw rod, this indirect conversion movement method cannot stably produce qualified products, and Efficiency cannot be improved (the reason is that the screw is driven by friction and rolling, the inherent friction and heat will cause the accuracy to change, and the high-speed state will lead to a sharp decline in the life of the screw); the efficiency is far less than the processing quotation given by the current market; moreover, the multi-head The screw drive method adds great difficulty and stability to the overall structure. There are also multiple heads added to the same axis, but the direction of their arrangement is relatively f...

[0002] Due to the current conventional machining centers on the market, only one head or advanced ones can only process with two heads at the same time. Due to the use of the traditional servo + screw rod, this indirect conversion movement method cannot stably produce qualified products, and Efficiency cannot be improved (the reason is that the screw is driven by friction and rolling, the inherent friction and heat will cause the accuracy to change, and the high-speed state will lead to a sharp decline in the life of the screw); the efficiency is far less than the processing quotation given by the current market; moreover, the multi-head The screw drive method adds great difficulty and stability to the overall structure. There are also multiple heads added to the same axis, but the direction of their arrangement is relatively fixed and cannot be moved, which will cause serious damage to the actual processing. process problems
