Referring to fig. 1, a drilling and tapping center with a movable spindle box is provided, which includes a machine tool bed 100 and a worktable 110 moving along a Y axis on the machine tool bed 100, the machine tool bed 100 is further provided with a gantry beam 200 and an X axis guide rail 210 arranged on the gantry beam 200, the gantry beam 200 is provided with a cross slide plate 300 sliding along the X axis and a spindle box 400 arranged on the cross slide plate 300, the spindle box 400 slides along a Z direction on the cross slide plate 300, the spindle box 400 is provided with a spindle motor and a drilling and tapping spindle 410 vertically arranged downwards, and the spindle box 400 is further provided with a tool magazine 420 at the outer side of the spindle box 400.

The work piece is installed by arranging the workbench 110 capable of moving along the Y axis in the drilling and tapping center of the moving headstock, and in the machining process, the workbench 110 moves along the Y axis on the machine tool bed 100, the headstock 400 provided with the drilling and tapping main shaft 410 moves along the X axis and the Z axis to be positioned, and the workbench 110 transversely arranged can move longitudinally along the Y axis, so that the machine tool can adapt to heavy cutting machining of larger work pieces, and the machining cost is effectively reduced.

In some embodiments, two Y-axis guide rails 101 are disposed on the machine tool body 100 at an interval in parallel, a Y-axis lead screw 102 is disposed between the two Y-axis guide rails 101, a guide groove matched with each Y-axis guide rail 101 is disposed at the bottom of the working table 110, and the Y-axis lead screw drives the working table 110 to move along the Y-axis guide rails 101 along the Y-axis.

In some of these embodiments, the worktable 110 is disposed transversely along the X-axis, and the worktable 110 is provided with a plurality of T-shaped grooves 111 disposed at intervals in parallel along the X-axis.

In some embodiments, the machine tool body 100 is provided with two X-axis guide rails 210 spaced in parallel along the X-axis, an X-axis screw is provided between the two X-axis guide rails 210, and the X-axis screw drives the cross slide 300 to slide laterally along the X-axis.

In some embodiments, the cross slide 300 is fixedly mounted with a spindle support 430, the spindle box 400 is mounted on the spindle support 430, the tool magazine 420 is suspended on the front side of the spindle support 430, and the spindle motor is mounted above the spindle support 430.

In some of these embodiments, a hydraulic counterweight assembly 440 is provided on the spindle support 430 to the side of the spindle motor.

The center of attacking is bored and is adopted headstock 400 to control and reciprocate, the structural style of workstation 110 back-and-forth movement, the center of attacking that bores that this technical scheme relates to sets up tool magazine 420 on cross slide 300 through main shaft support 430, for the setting that traditional C type machine bores the center and adopts workstation 110 to control, this headstock 400 structural feature that reciprocates has following advantage:

first, since the width of the headstock 400 is much shorter than the length of the table 110, the width of the machine tool is one third less than that of a machine tool having a structure in which the table 110 moves left and right under the same X-axis stroke, and the longer the machine tool, the more the width is saved, the larger the stroke of the tapping center, and the more advantageous the device is.

Secondly, because the workbench 110 only moves back and forth, the machine tool only has the Y-axis screw 102 and the Y-axis guide rail 101 in the machining area, and the X-axis guide rail 210 and the X-axis screw are both arranged on the gantry beam 200, so that the protection of the machining area of the machine tool is easier to arrange, the cost of the protection arrangement is lower, and the failure rate of the equipment is lower.

This lathe adopts gantry structure, and headstock 400 sets up on cross slide 300, and headstock 400 moves about at will, and at headstock 400 in-process of moving at will, its headstock 400 all is symmetrical with cross slide 300, can not produce unsettled deformation, therefore equipment rigidity is good.

The workbench 110 of the machine tool only moves back and forth, the condition that the workbench 110 is suspended when the workbench 110 moves to one end is avoided, the influence on the precision change of the workbench 110 is small, and therefore the machining precision of the drilling and tapping center is greatly improved.

Meanwhile, the workbench 110 only moves back and forth, so that the workbench 110 is larger in bearing capacity and more suitable for machining large parts.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
