SU1202749A1 - Milling machine with n/c for machining a set of turbine blades - Google Patents

Description

The invention relates to machine-tool construction and can be used for machining complex curvilinear surfaces such as turbine blades.

The purpose of the invention is to improve the operating conditions.

The goal is achieved by installing all the working bodies on one rack in such a way that the installation and removal of the blades is performed on the side opposite to the tool block, which improves the view of the cutting zone.

FIG. 1 shows the machine, front view in FIG. 2 is the same, section A-A in FIG. one; in fig. 3 - the same, section BB in FIG. one.

The milling machine for processing a set of turbine blades contains a frame 1 consisting of the base of the lateral sides in the form of columns 3 and 4 and the top beam 5. On the frame 1, which is the basic unit of the machine, all the other mechanisms of the machine are mounted. A traverse 6 is mounted on the rear vertical guide columns, carrying on itself a horizontal cross sledge 7 with a block of mills 8 consisting of a set of swivel heads 9 in which mills 10 are mounted. On the block of mills it is installed when turning heads 11. vertical pillars are made on the sides of the columns, on which are mounted sleds carrying a beam

lunettes 12 with a drive of their rotation 13 and a beam 14 with an upper drive of rotation of the blades 15. On the top beam

5 installed drive 16 movement 5 crosshead 6 with a unit of cutters and drive

17 for moving the beam of the lunettes 12. In the base 2, the lower drive 18 for rotating the blades 15 is mounted.

The work of the machine is as follows.

The blade to be machined is attached to the lower and upper ends and is rotated by means of a Hii-iero and upper blade rotation drives. The beam 14 with the upper drive rotation of the blades 15, moving along the vertical guides of the side columns 3 and 4, is adjusted to the size of the blade. During operation, the blades are supported by lunettes installed in the beam: ponet 12, which moves along the same vertical guides of the side columns 3 and 4. BLOCK of cutters 8 during processing the blade profile has a booster capacity to move in three directions perpendicular: vertical - together with traverse 6 on the rear and right side of the lateral columns 3 and 4, longitudinal - with the cross dignity 7 on the traverse

6 and the transverse - milling head unit along the cross dignity m 7, as well as rotation to change the angle of the cutter with respect to the blade axis.
