Vertical double-sided milling machine of gantry

Abstract

The invention relates to a vertical double-sided milling machine of a gantry, which comprises a gantry frame (1) and a milling machine body (4) which is fixed on the gantry frame (1), wherein an upper milling mechanism (7) and a lower milling mechanism (8) for milling workpieces are arranged above and below the milling machine body (4) respectively; the milling machine body (4) is also provided with a work bench (902) which is used for machining the workpieces and can be driven by a work bench drive mechanism (9) on the gantry frame (1) to move forwards and backwards in a reciprocating manner; the gantry frame (1) is also provided with an upper milling drive mechanism capable of driving the upper milling mechanism (7), an upper milling support mechanism for supporting the upper milling drive mechanism, a lower milling drive mechanism capable of driving the lower milling mechanism (8), and a lower milling support mechanism for supporting the lower milling drive mechanism. The vertical double-sided milling machine for the gantry has the advantages that: two large surfaces of a large panel can be machined simultaneously; each surface is milled by three milling cutters, so that one surface can be milled at a time; and the vertical double-sided milling machine of the gantry is high in efficiency.

Description

technical field [0001] The invention relates to a milling machine, in particular to a gantry vertical double-sided milling machine. Background technique [0002] At present, most of the milling of plate blanks still use ordinary milling machines. The diameter of milling cutters of general specifications does not exceed 400mm, the amount of milling is generally 2mm to 3mm, and the feed rate is 200mm / min to 400mm / min. Only by improving these parameters To improve production efficiency is limited. [0003] For the milling of plate blanks, ordinary milling machines have many shortcomings. For example, most milling machines can only process one surface in one milling process. If you want to process other surfaces, you need to unload the processed workpiece, re-clamp and position it, and then process it, which will greatly affect the processing efficiency. [0004] Another disadvantage is that most of the existing ordinary milling machines use a milling cutter to feed multiple t...

Problems solved by technology

[0007] Another purpose of the present invention is to solve the problem that most of the common milling machines in the prior art use a milling cutter to feed multiple times, which cannot guarantee that the milling of one surface can be completed in one feeding process. If the workpiece size is too large, it is necessary to Changing the relative position between the milling cutter and the workpiece to feed repeatedly will significantly reduce the milling efficiency. If the workpiece size is too large, it is difficult for the existing milling machine to meet the processing requirements. Even the existing multi-face milling milling machine rarely processes large The technical problem of the workpiece size; provide a kind of gantry vertical machine that can process workpieces of different sizes, and the workpiece is clamped and positioned by hydraulic cylinders on both sides. double-sided milling machine
