specific Embodiment approach 1

[0008] Specific implementation mode one: in conjunction with Fig. 1~ Figure 5 Describe this embodiment, the milling machine of this embodiment includes gantry frame bed, base 39, electric spindle 24, X-axis servo drive assembly, Y-axis servo drive assembly, Z-axis servo drive assembly, work turntable assembly, Cylinder assembly, microscope assembly, Z-axis plate 21 and upper support frame 46; the gantry frame bed is fixed on the base 39, and the gantry frame bed is composed of a beam 32 and two columns 2, the two The two columns 2 are arranged oppositely, and the beam 32 is fixed on the two columns 2. The X-axis servo drive assembly consists of an X-axis AC servo motor 60, an X-axis ball screw 62, an X-axis linear guide 49, and an X-axis Guide rail bottom plate 47, X-axis micro switch 61, X-axis grating ruler 63 and X-axis grating ruler reading head 59, the Y-axis servo drive assembly is composed of Y-axis AC servo motor 52, Y-axis ball screw 54, Y-axis Axis linear guide rai...

specific Embodiment approach 2

[0009] Specific embodiment two: this embodiment is described in conjunction with Fig. 1 and Fig. 2, and the difference between this embodiment and specific embodiment one is: the milling machine of this embodiment also includes two chip baffles 55; A chip baffle 55 is respectively equipped with on the left and right sides of 44. This setting is beneficial to the removal of coolant and chips, and reduces the thermal deformation of the bed caused by the temperature change of the cutting fluid.

specific Embodiment approach 3

[0010] Specific embodiment three: This embodiment is described in conjunction with Fig. 1 and Fig. 2. The difference between this embodiment and specific embodiment one or two is: the milling machine of this embodiment also includes an X-axis dust cover 4; The dust cover 4 is arranged directly above the X-axis ball screw 62 , and the lower end of the X-axis dust cover 4 is connected to the beam 32 . Such arrangement can prevent dust and chips from falling on the X-axis ball screw 62 and ensure the normal rotation of the X-axis ball screw 62 .

Abstract

The invention relates to a small five-axle-linkage numerical control milling machine, relating to a small numerical control milling machine. The invention aims at problems of conventional-size precise machine tool during cutting process of tiny parts, including large machine tool volume, high processing cost, low efficiency, uneconomical energy and space consumption and difficulties in the processing of complex tiny parts of three-dimensional camber structure. A portal frame-typed machine body is fixed on a base; and X-axis servo driving assembly is fixed on the portal frame-typed machine body; the upper end surface of the base is fixed with a Y-axis servo driving assembly; a Z-axis panel is connected with the X-axis servo driving assembly; a Z-axis servo driving assembly is fixed on the Z-axis panel; an electric principal shaft is fixed on the Z-axis servo driving assembly; a cylinder is connected with the Z-axis servo driving assembly; a microscope is connected with the Z-axis servo driving assembly; a working turntable provided with a motor therein is driven by a driving motor and forms a composite turntable rotating around the Z axis and the Y axis. The numerical control milling machine can realize five-axle linkage so as to satisfy processing requirements of three-dimensional camber structure and complex tiny parts.

Description

technical field [0001] The invention relates to a small numerically controlled machine tool, which belongs to the field of mechanical processing equipment. Background technique [0002] With the continuous development of science and technology, the demand for various micro-miniature products in the fields of civil and national defense continues to increase, and the requirements for the function, structure complexity, and reliability of micro-devices are also getting higher and higher. MEMS (micro-electromechanical system abbreviation) technology based on silicon technology can realize the processing of tiny parts, but the machinable materials are limited, the shape of parts is limited to two-dimensional or quasi-three-dimensional structures, it is difficult to process complex three-dimensional structures, and the relative accuracy (parts The ratio of tolerance to feature size) is low, and in many cases, tiny parts have complex three-dimensional structures. Therefore, the res...
