Y-axis mechanism of turning and milling composite machine tool

Abstract

The invention relates to a movement mechanism on a machine tool, in particular to a Y-axis mechanism of a turning and milling composite machine tool. The Y-axis mechanism of the turning and milling composite machine tool comprises a Y-axis upright post and a knife rest, wherein the Y-axis upright post is vertically and fixedly arranged on an X-axis sliding plate. The Y-axis mechanism of the turning and milling composite machine tool is characterized in that a Y-axis sliding plate capable of sliding in the Y direction is arranged on the left side of the Y-axis upright post; a knife rest is arranged on the Y-axis sliding plate; a vertical auxiliary guide rail is further arranged on the X-axis sliding plate; the left side of the knife rest is slidably connected with the auxiliary guide rail;and a locking oil cylinder is arranged between the knife rest and the auxiliary guide rail. According to the Y-axis mechanism of the turning and milling composite machine tool provided by the invention, by means of the structure, the rigidity of the Y-axis sliding plate is improved, the Y-axis sliding plate and the knife rest are stressed well, the cutting performance is good, the anti-backlash effect can be achieved, and the precision of a machine tool is high.

Description

technical field [0001] The invention relates to a motion mechanism on a machine tool, in particular to a Y-axis mechanism of a turning-milling compound machine tool. Background technique [0002] Taking the horizontal turning center as an example, a vertical column perpendicular to the X and Z planes is added to the saddle and slide plate, and there is a Y-axis guide rail perpendicular to the X and Z-axis guide rails on the column, and a Y-axis guide rail on the Y-axis guide rail. Skateboard, on which a powered tool holder is installed. The powered tool holder can move along the three directions of X, Y, and Z. Driven by the feed motor and coordinated with the C-axis, it can complete the turning and milling of complex parts. [0003] The turning and milling center is a high-grade inclined bed CNC lathe with four-axis linkage of X, Y, Z, and C. The traditional turning and milling compound Y axis is an interpolating Y axis, which is created by the two axes X1 and X2. The disad...

[0003] The turning and milling center is a high-grade inclined bed CNC lathe with four-axis linkage of X, Y, Z, and C. The traditional turning and milling compound Y axis is an interpolating Y axis, which is created by the two axes X1 and X2. The disadvantage is that Y The axis stroke is small, and the creation of the Y axis requires the support of the CNC system, and the precision is low and the fast moving speed is slow

Another mainstream turning and milling center belongs to the orthogonal Y-axis structure, but the cutting rigidity is poor due to the large overhang of the tool post
