Abstract

The utility model relates to a main spindle box of a machining centre which includes a main spindle box and a main spindle motor, the main spindle box is hanged on a vertical pole guide rail, the main spindle box is equipped with a main spindle box nut, the main spindle box nut connects with a lead screw, the main spindle box is equipped with a chief axis, an upper part of the chief axis is equipped with a pressure cylinder, a down part of the chief axis is equipped with a tool bit; the main spindle motor connects with a synchronizing wheel of the main spindle motor, the synchronizing wheel of the main spindle motor connects with the chief axis through a synchronous belt. The utility model has advantages that: the main spindle box of the machining centre adopts an inside-outside layers strengthen rib structure, which increases rigidly of the main spindle box obviously, reduces shake and twitter of moving and working course, enhances machine precision and surface mass of the product greatly.

Description

A kind of machining center main spindle box

Technical field

The utility model relates to a kind of machining center main spindle box.

Background technology

Machining center is mainly used in the heavy complicated precision component of processing, following several situation is arranged: 1, when the motion of workbench cross when main spindle box and workbench work, workbench is made X, Z to motion, main spindle box is made Y to motion, main spindle box on column, just have hang, side is hung two kinds of forms, be applicable to medium-sized complex parts boring, multiple operation processing such as mill; 2, when the main spindle box cross moves, main spindle box is made X, Z to motion, and workbench is made Y to motion, be applicable to middle-size and small-size part boring, multiple operation processing such as mill; 3, main spindle box side extension and column, main spindle box are made Y, Z to motion, and this distribution form and planing bench type boring and milling machine with horizontal spindle are similar, and workbench is made X to motion, multiple operation processing such as be applicable to medium-sized part boring, mill; Main spindle box is as the vitals of machining center, arranging lathe working-spindle and driving parts thereof and the corresponding additional mechanism providing additional operation crucial effects of getting up, and traditional main spindle box only adopts the internal layer reinforcement, in motion and process, very big vibrations and shake can occur, make the machining accuracy of product and surface quality be difficult to guarantee.

The utility model content

The purpose of this utility model provides a kind of machining center main spindle box, only adopts the internal layer reinforcement to overcome existing main spindle box, very big vibrations and shake can occur in motion and process, makes the machining accuracy of product and surface quality be difficult to the deficiency that guarantees.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of machining center main spindle box comprises main spindle box and spindle motor, and described main spindle box is articulated on the column guide rail, main spindle box is provided with the main spindle box nut, and the main spindle box nut connects leading screw, is provided with main shaft in the main spindle box, the top of main shaft is provided with pressurized cylinder, and the bottom of main shaft is provided with cutter; Described spindle motor connects the spindle motor synchronizing wheel, and the spindle motor synchronizing wheel is connected with main shaft by being with synchronously.

The beneficial effects of the utility model are: adopt inside and outside double-deck reinforcing rib structure, the rigidity of main spindle box is improved significantly, can reduce the vibrations and the shake of motion and process simultaneously again, improve the machining accuracy and the surface quality of product greatly.

Description of drawings

Fig. 1 is the internal structure schematic diagram of a kind of machining center main spindle box described in the utility model;

Fig. 2 is the B-B side view of Fig. 1.

Among the figure:

1, main spindle box; 2, main shaft; 3, pressurized cylinder; 4, spindle motor; 5, spindle motor synchronizing wheel; 6, be with synchronously; 7, cutter; 8, column guide rail; 9, leading screw; 10, internal layer reinforcement; 11, outer reinforcement.

The specific embodiment

As shown in Figure 1, a kind of machining center main spindle box described in the utility model, comprise main spindle box 1 and spindle motor 4, described main spindle box 1 is articulated on the column guide rail 8, and main spindle box connects leading screw 9, be provided with main shaft 2 in the main spindle box 1, the top of main shaft 2 is provided with pressurized cylinder 3, and the bottom of main shaft 2 is provided with cutter 7, and cutter 7 is to carry out clamping by pressurized cylinder 3, described spindle motor 4 connects spindle motor synchronizing wheels 5, and spindle motor synchronizing wheel 5 is by being with 6 to be connected with main shaft 2 synchronously.

As described in Figure 2, main spindle box adopts the mode of

internal layer reinforcement

10,11 combinations of outer reinforcement, make the rigidity of main spindle box be significantly improved, during concrete the use, Z axle servomotor drives leading screw 9 by shaft coupling and rotates, it serves as that guiding moves up and down with column guide rail 8 that leading screw 9 rotations drive main spindle box 1, and spindle motor 4 drives spindle motor synchronizing wheels 5 and rotates, and by being with 6 drive main shafts 2 and cutter 7 to rotate to finish synchronously piece surface is processed then.
