Description

The utility model relates to modular machines.

A five-axis machining center is known, comprising a bed, a rotary table, a spindle, a cross caliper, a longitudinal caliper, a vertical caliper, non-contact linear guides for each of the said calipers and non-contact circular guides for a rotary table and a turning spindle / US2002050508, 02.05.2002 /.

The design of the calipers of the center allows the manufacture of parts with small dimensions with high accuracy of the form.

The utility model is aimed at the possibility of manufacturing high-precision overall parts, i.e. increase the dimensions of the processed products with high precision molds.

To achieve this technical result, a five-axis machining center is proposed, comprising a bed, a rotary table, a turning spindle, a cross support, a longitudinal support, a vertical support, non-contact linear guides for each of the mentioned calipers and non-contact circular guides for the rotary table and turning spindle.

The bed is made with the aforementioned first non-contact straight guides for the longitudinal support, which includes a portal and racks with the second non-contact straight guides that are mounted on the bed.

In this case, the portal traverse is provided with the third vertical said non-contact rectilinear guides for the vertical support, which is provided with a prismatic housing with the first mentioned circular guides for the turning spindle, and the said transverse support is provided with the second mentioned circular guides for the rotary table.

The vertical support is made with a prismatic housing, the four faces of which form the surfaces of the supports, having a section in parallel section shape and continuing to interact with the surfaces of the supports of said vertical guides.

The utility model is illustrated by drawings of a five-axis machining center for machining brittle materials.

The five-axis machining center for machining a case made of brittle material includes means for positioning the workpiece and means for main forming relative movement of the tool, forming a coordinate-organized mechanical structure of the main movement of the tool relative to the surface of the workpiece layer being processed.

The five-axis machining center contains (Fig. 1) a bed 2 mounted on the base 1, a rotary table 8 (first coordinate B), a turning spindle 3 (second coordinate C), a cross support 6 (third coordinate X), a longitudinal support 5 (fourth coordinate Z ), vertical support 7 (fifth coordinate Y).

The bed 2 is made with the first non-contact rectilinear guides 9 for the longitudinal caliper 5 and with the second non-contact rectilinear guides 16 for the transverse caliper 6.

The longitudinal support 5 includes a portal 10, which is configured to install a vertical support 7 and move along the corresponding third guides of the frame 2.

The portal 10 includes a traverse 17, the ends of which are fixed on the uprights 12, which on the opposite side are arranged to move along the respective guides 9 of the frame 2.

The vertical support 7 is equipped (Fig. 3) with a housing 15 in which the first non-contact circular guides 21 (coordinate C) are mounted for the turning spindle 3.

The four faces of the housing 15 form surfaces, the cross section of which has the form of a parallelogram interacting with the surfaces of the supports of the third vertical non-contact rectilinear guides 19.

The housing 15 is located between the non-contact rectilinear guides 19, which are on the one hand connected by screws 11 to the traverse 17, and on the opposite side by screws 13 are attached to the plate 14.

The transverse support 6 is made with second non-contact circular guides 20 (coordinate B, Fig. 5) for the rotary table 8, which is arranged to process the workpiece fixed in the turning spindle 3 using a cutting tool that is installed in the grinding spindle 4.

In this case, the working movements of the cutting tool can be kinematically organized by one actuating system, consisting of a transverse support 6 and a grinding spindle 4.

Workpiece movement of the workpiece is also organized by another executive system, consisting of a longitudinal support 5, a vertical support 7 and a turning spindle 3.

A system of numerical program control (not shown) is provided, which ensures the formation of an integral formative relative movement of the workpiece and tool according to a given program during the technological cycle.

Five-axis machining center for machining a billet of brittle material works as follows.

On the grinding spindle 4, located on the turntable 8 and made with a cylindrical seating surface, the tool - the grinding wheel is based and fixed.

The workpiece is placed in the holes on the end surface of the turning spindle 3 directly or through the corresponding faceplate.

To bring the workpiece into the cutting zone, its location is first pre-adjusted according to the coordinates Z and Y using a vertical support 7 and a longitudinal support 5, respectively.

Then, by means of the transverse support 6, a grinding wheel is brought into the cutting zone (if necessary, its position relative to the workpiece is adjusted by means of the rotary table 8), the rotation of the grinding wheel is turned on, and by moving along the Z coordinate, the workpiece is brought into contact with the grinding wheel. After touching the Z coordinate, the zero position is fixed, relative to which a further cutting of the circle into the workpiece is carried out.

To perform milling on the grinding spindle 4, the milling head is fixed with a diamond cutter installed in it, the adjustment and processing is carried out according to the algorithm described above.

To carry out the turning operation, a tool holder is mounted on the rotary table 8 and a turning tool is fixed in it.

At the same time, the grinding spindle 4 and two tool holders can be fixed on the turntable 8.

Thus, grinding and turning operations at the five-axis machining center can be carried out in one cycle.
