Multi-axial electric machinery process equipment

Abstract

A machine tool (1) driven by linear motors (8, 9, 10) along a plurality of axes (X, Y, Z) and unusually robust and rigid, comprises a bed (2) which defines at least a first axis (X), at least one column (3) operably connected and supported only at one of its ends (7) by said bed (2), for its guided movement along the first axis (X), said at least one column (3) extending away from the bed (2) to define a second axis (Y), at least one saddle mount (4), for its guided movement along a third axis (Z) and supporting a spindle (6) for the movement of a tool, wherein said at least one column (3) comprises a portal structure having a first shoulder (11) opposed to a second shoulder (12) such as to define a window (13) within which the saddle mount (4) is arranged, and wherein, between said opposed shoulders (11, 12) and the saddle mount (4), linear motors (9) are interposed such as to move the saddle mount (4) along said second axis (Y), producing an effect of attraction of the shoulders (11, 12) towards the saddle mount (4).

Description

technical field [0001] The invention relates to a multi-axis linear motor processing equipment. [0002] More specifically, the subject of the invention relates to a machining device with three axes, where the device can be, for example, a chip removal tool such as a milling cutter, moved at high speed along a feed channel by means of a linear motor . Background technique [0003] Realization of this type of processing requires the fulfillment of the following conditions, that is, while moving the device continuously and rapidly, even at a strong acceleration of 0.5G, the precision of the processing can be guaranteed at the same time. This requires the design of a structure that is stiff enough not to deform during machining, yet rigid enough not to start vibrating due to the influence of motor operation or due to the mechanical stresses generated during machining. [0004] Generally, these processing devices include a column extending in the vertical direction (Y axis) wh...

Problems solved by technology

[0006] The defect of the processing equipment involved in the patent document US5,368425 is that only a very heavy and bulky structure can be used to meet the above working conditions, and also, for its dynamic structural parts or processing equipment parts that may move during processing, especially The pillars that make up the Y axis of the device are all flawed

In fact, this defect is reflected in the increase of equipment cost and the increase of overall weight
