Abstract

FIELD: machine-tool industry. SUBSTANCE: bed-frame 1 has pole 2 with vertically movable spindle stock 6, rear pole 4 and crossing table 3. Front pole 2 is located in cantilever, that is capable to move along longitudinal guides of bed-frame 1 having vertical shaft, around which pole 2 is capable to turn and move along it. Machine is used for different operations: during cutting and boring operations lathe mandrel is set in spindle 13 and chisel holder is mounted on table 3; during long pieces cutting operations and flat grinding they turn pole 2, placing spindle 13 perpendicular to longitudinal guides 5 of bed-frame and during high pieces processing pole is moved along vertical axis. EFFECT: machine is effective in cutting and grinding operations. 2 cl, 6 dwg

Description

 The invention relates to machine tools and can be applied in machines with manual control, including those used as consumer goods.

 A well-known universal machine containing a bed, on the longitudinal guides of which there is a front pillar with a spindle head installed with the possibility of moving along it in the vertical direction, a cross table and a rear pillar with a support device installed with the ability to move around the pillar.

 The disadvantage of the prototype is that it has limited technological capabilities.

 The purpose of the invention is the expansion of technological capabilities of the machine.

 This goal is achieved by the fact that the machine is equipped with a bracket with a vertical axis fixed in it, mounted with the possibility of movement along the additional longitudinal guides inserted into the machine, placed on the bed, while the front rack is placed in the bracket with the possibility of rotation around the vertical axis.

 In addition, the front pillar is mounted to move along the vertical axis.

 In FIG. 1 schematically shows a machine configured for milling short parts, general view; figure 2 is a General view of the machine configured for turning; figure 3 is a General view of the machine, configured to handle long parts; figure 4 is a view along arrow A in figure 1; figure 5 is a view along arrow B in figure 1; figure 6 is a view of the tailstock.

 The universal machine includes a bed 1 with a front pillar 2, a cross table 3 and a rear pillar 4 mounted on the longitudinal guides 5 of the bed. The headstock 6 is mounted on the vertical guides 7 of the rack 2. The rack is mounted with the possibility of rotation around the vertical axis 8 and move along it. In this case, the vertical axis 8 is fixed in the bracket 9 mounted on the frame with the ability to move along its additional longitudinal guides 10. In the bracket 9 there are installed screws 11 for fixing its position. On the rack 2, from above, a screw 12 is fixed for vertical movement of the rack along the vertical axis 8.

 The rotation of the spindle 13 is carried out from the electric motor 14 through a belt drive 15. The electric motor is mounted on a swing plate 16. In this case, the swing axis 17 is fixed to the rack.

 The rear strut 4 is made integral of the lower part 18 mounted on the longitudinal guides 5 of the bed, and the upper part 19, made with the possibility of vertical movement relative to the lower part in a vertical plane.

 The work of the machine is as follows. Rotation from the electric motor 14 through the belt drive 15 and the gearbox is transmitted to the spindle 13 of the machine. When milling and boring, the corresponding tool is installed in the spindle. During turning operations, a turning chuck is attached to the machine spindle, and a tool holder is mounted on the cross table 3. The change in the frequency of rotation of the spindle is carried out by moving the belt 15 into the corresponding pulley stream. Moving the working bodies (cross table 3, headstock 6) is carried out manually using the corresponding handwheels 20. If necessary, through the feed box 21, you can turn on the mechanical feed.

 When turning and milling short parts, the rack 2 occupies the position shown in figure 1, while the spindle 13 is parallel to the longitudinal guides 5 of the frame.

For milling of long parts and surface grinding work, the rack 2 is rotated 90 ° ^{about the} vertical axis 8. In this case, the spindle 13 is located perpendicular to the longitudinal guides 5 of the bed (see figure 3). If necessary, the rack 2 may occupy an intermediate position in which it is fixed with screws 22 of the terminal clamp.

 When machining long parts, the spindle 13 must be located in the center of the bed. For this, the bracket 9 with a vertical axis 8 and a stand with a spindle head 6 is moved along the additional guides 10 to the desired position and is fixed with screws 11.

 When machining tall parts, the post 2 with the screw 12 moves up along the vertical axis 8 to the desired position and is fixed with screws 22 of the terminal clamp.
