Abstract

The invention discloses a ram device of a gantry machining center. A ram is arranged on a slide carriage through a vertical linear rolling lead rail; a ram feeding device is arranged between the slide carriage and the ram; the ram is driven to move up and down along the vertical linear rolling lead rail by the ram feeding device; a boring spindle is driven to move inside a milling spindle along a sliding key by a boring spindle feeding device; and a spindle servo motor is connected with the milling spindle through a transmission gear, and drives the milling spindle to rotate. According to the ram device of the gantry machining center, the working depth of a hole is increased; the machining precision is improved, and the operation is facilitated.

Description

A kind of gantry machining center ram apparatus
Technical field
The present invention relates to a kind of metal cutting machining tool, especially relate to a kind of gantry machining center ram apparatus.
Background technology
In traditional gantry machining center, fixed installation main axle unit in side's ram, main shaft only rotates in ram, non-telescope feed motion, this is so that when the gantry machining center deep hole processing, but working depth, precision are all affected significantly and are restricted, and usually need multiple working procedure when the machining high-precision part, need other machining tool further to improve the machining accuracy of part and the hole working depth of deep-hole parts.
Summary of the invention
The objective of the invention is: for the technical problem of above-mentioned existence, provide a kind of gantry machining center ram apparatus that increases the hole working depth, improves machining accuracy, convenient operation.
Technical scheme of the present invention is: comprise slide carriage, ram, the boring and milling axle, ram is installed on the slide carriage by the vertical line rolling guide, the ram feed arrangement is housed between slide carriage and ram, the ram feed arrangement drives ram and moves up and down along the vertical line rolling guide, milling spindle is installed in the ram by rolling bearing, between the boring axle of milling spindle and inside a pair of feather key is housed, boring axle feed arrangement is housed between ram and boring axle, boring axle feed arrangement drives the boring axle and moves along feather key in milling spindle, spindle servo electric machine is equipped with in the ram side, and spindle servo electric machine connects milling spindle by transmission device, and drive milling spindle rotation.
Described transmission device is synchronous belt transmission device.
Compensating cylinder is equipped with in the both sides of described ram, and the two ends of compensating cylinder are connected on ram end and the slide carriage.
The invention has the beneficial effects as follows: the present invention is by being installed in the ram feed arrangement between slide carriage and the ram, driving ram moves up and down along the vertical line rolling guide, by being installed in the boring axle feed arrangement of ram and boring between centers, make the boring axle flexible along feather key in milling spindle, spindle servo electric machine is installed in the ram side, drive the milling spindle rotation by transmission device, milling spindle drives the rotation of boring axle by feather key.When deep hole processing, can use lengthened tool arbor, utilize the contracting of boring shaft extension can reach the purpose of deep hole processing, namely alleviate operator's labour intensity, improve again machining accuracy and efficient, widen the range of work of lathe.
