The cutter rotary towers (9 and 9') can move in the vertical Z-axis direction by means of vertical sliding seats (5 and 5') and a first guiding mechanism (4) on the side walls (2 and 2'), and the cutter rotary towers can move in the horizontal X-axis direction by means of horizontal sliding seats (8 and 8') and a guide rail (7) on the vertical sliding seats (5 and 5').

Description

Lathe

Technical field

The present invention relates to a kind of lathe, this lathe has vertically suspended main shaft and two tool turret.

Background technology

In the prior art, this lathe is known.DE19900294A1 relates to a kind of lathe for turnery processing shaft-like workpiece.Be provided with multiple guide rail of being vertically oriented in the front of frame and at the slide of moving on rails, central slide wherein can be equipped with work spindle.This work spindle is attached troops to a unit tailstock or corresponding main shaft.In the both sides of this work spindle, be provided with the cross sliding board of the tool rest had for fixed or driven cutter specular.

Summary of the invention

Task of the present invention is to provide a kind of lathe of the machine stiffness be of compact construction and improve.This task has been come by lathe according to a first aspect of the invention.Favourable improvement project is the theme of other side.

According to a favourable aspect of the present invention, frame is in the form of post with multiple vertical wall.The outstanding work spindle established is placed on the antetheca of frame, and two toolframes can rely on vertical slide to move in vertical Z-direction on frame side wall.Described vertical slide is equiped with horizontally-guided mechanism in its side towards working space, and this knife rest can move in the X-axis direction in this horizontally-guided mechanism.In the Alternate embodiments with Y-axis, described Y-axis is advantageously arranged on the sidewall of described post.Along Z-direction or Y-direction and X-direction, guiding mechanism is set in three sides of the square cross section of described frame, achieves structure closely and improve machine stiffness.

Detailed description of the invention

Fig. 1 shows the schematic diagram of lathe.The details of drive unit and control device is not shown.Frame is implemented to post 1, and this post has square cross section, upright side walls 2,2 ' and is equally also vertical antetheca 3.Sidewall 2 and 2 ' are provided with multiple the first spaced guiding mechanism 4, vertical slide 5,5 ' can on this first guiding mechanism in the vertical direction (along Z axis) mobile.The motor 6,6 that is driven through in Z-direction ' realizes with unshowned ball screw framework.The guide rail 7 of vertical slide 5,5 ' be equipped with for horizontal slide 8,8 ' itself.Tool turret 9,9 is ' together with cutter 10 with can on pivot axis 19,19 ' mode of rotation be contained in horizontal slide 8,8 '.The antetheca 3 of post 1 is provided with the second guiding mechanism 11.The outstanding main shaft 12 established or its tailstock of attaching troops to a unit can move, can hold the workpiece 17 of different length on the second guiding mechanism.Workpiece 17 is by conveyer belt 14,14 ' send into " loaded " position 18,18 '.This workpiece is clamped by tool turret 9,9 ' on fixture 13,13 ', by move along guide rail 7 and around pivot axis 19,19 ' pivotable be loaded into main shaft 12 and be sent back to again after completing processing conveyer belt 14,14 '.At the rear side of lathe, switch board 15 and hydraulic cooling device 16 are arranged back-to-back.In this way, even if when closely multiple stage machine is set up in arrangement, also can well close to both.Two Y-axis are equipped with according to the lathe of Fig. 2.Now, these vertical slides 5,5 are ' in the form of longitudinal supporting plate.On longitudinal supporting plate, described Y slide 20,20 ' can move in a controlled manner along Y direction on the 3rd guiding mechanism 21.Y slide itself be equipped with for horizontal slide 8,8 ' guide rail 7.Therefore, tool turret 9 and 9 ' can move in three of a coordinate system of machine major axis X, Y, Z-direction.
