Double-column horizontal machining center with vertically moving worktable

Abstract

The invention discloses a double-column horizontal machining center with a vertically moving worktable. The double-column horizontal machining center comprises a body, columns, a worktable support, a lifting mechanism and a tool changer, wherein the worktable support is used for mounting the worktable, and the lifting mechanism drives the worktable to ascend or descend. The double-column horizontal machining center is characterized in that two columns are vertically and parallelly arranged on two sides of one end of the body, two sides of the worktable support are slidably connected with the columns, the lifting mechanism for driving the worktable to ascend or descend is mounted on the worktable support, a cross sliding table capable of horizontally sliding along the body is arranged on the body, a ram capable of vertically sliding along the body is arranged above the cross sliding table, a spindle mechanism is mounted on the ram, the axis line of the spindle mechanism is consistent with the vertical direction of the body, a tool changer support frame is fixedly connected onto the body, and the tool changer is mounted on the tool changer support frame. The double-column horizontal machining center has the advantages of compact structure, high efficiency and precision, easiness in modular design extension and particular suitability for efficient and flexible production lines for assembling key parts in industries such as automobiles.

Description

technical field [0001] The invention relates to machining equipment, in particular to a vertically movable worktable double-column horizontal machining center. Background technique [0002] High speed, high precision, and flexibility are important trends in the development of the machining industry, especially in the automotive industry. It has become an inevitable choice to use an efficient and flexible production line composed of horizontal machining centers for the processing of key engine parts such as cylinder blocks and cylinder heads. [0003] Efficient and flexible production lines have special requirements for horizontal machining centers, such as: the effective use of plant space requires the machining center to have a small horizontal dimension and save floor space; high processing efficiency, high chip removal rate, and large flushing water volume require the machining center Large chip space and smooth chip removal; high processing efficiency requires the horizo...
