Detailed description of the invention
Below, be described according to the lathe of accompanying drawing to embodiment of the lathe representing embodiment.Fig. 1 is the front view of lathe, and Fig. 2 is the longitudinal section of lathe, and Fig. 3 is the stereogram of lathe.Fig. 3 eliminates the diagram to tool magazine 6 and support plate 7.In the following description, by upper and lower, the left and right represented by the arrow that uses in accompanying drawing and front and back.
Lathe comprises the pedestal 1 of rectangle, and this pedestal length is in the longitudinal direction longer.Column 2 is erected at the rear portion of pedestal 1.Work holding portion thereof 10 for holding workpiece is located at the front portion of pedestal 1.Work holding portion thereof 10 comprises: Y-direction moving part 11, and it can move in the longitudinal direction; X-direction moving part 12, it can move in the lateral direction; And work stage 13, workpiece can be configured in this work stage.
Y-direction moving part 11 is located on pedestal 1.X-direction moving part 12 is located on Y-direction moving part 11.Work stage 13 is located on X-direction moving part 12.Move in the lateral direction by making X-direction moving part 12 and Y-direction moving part 11 moved in the longitudinal direction, determine to be configured in workpiece in work stage 13 in the lateral direction with the position on fore-and-aft direction.
The front surface (front) of column 2 is located at by the Z axis guide rail 20 (with reference to Fig. 4) extended in the vertical direction.Main tapping 3 is located at Z axis guide rail 20.Main tapping 3 keeps this main shaft 4 in the mode that main shaft 4 can rotate about the axis, and this main shaft 4 take above-below direction as axis direction.Main tapping 3 is in triangular prism shape.An apex portion of main tapping 3 is positioned at front side.An above-mentioned apex portion is for keeping main shaft 4.Two other apex portion lays respectively at the left and right sides.The end by stud sides of main tapping 3 near two other summit above-mentioned has protuberance 3a (with reference to Fig. 4), and this protuberance 3a extends in the mode parallel with the front surface of column 2.The rear surface of main tapping 3 can be located at the sliding part 21 of Z axis guide rail 20 tabling (with reference to Fig. 4).By making sliding part 21 move up and down on Z axis guide rail 20, thus main tapping 3 is moved up and down.
Two support plate 7 Self-stabilised posts 2 are forwards given prominence to.Two support plates 7 in the left and right sides side by side.Support plate 7 is for supporting tool magazine 6, and this tool magazine 6 is for keeping cutter.Tool magazine 6 has multiple keeping arm (omitting diagram).Each keeping arm can keep cutter.When main tapping 3 moves towards work stage 13, remain on Cutting tool installation manner on keeping arm bottom on main shaft 4 downwards.When main tapping 3 is moved upward near work stage 13, keeping arm keeps the cutter be arranged on main shaft 4.
Fig. 4 be with IV in Fig. 1-IV line for cutting line carry out cutting after the enlarged partial sectional view that obtains.The protuberance 3a of main tapping 3 is located at by side cover 5.Side cover 5 is formed as the lengthwise tabular extended in the vertical direction, and is crank-like when overlooking.Side cover 5 length in the vertical direction and main tapping 3 same length in the vertical direction.Side cover 5 also can be outstanding a little from the two ends up and down of main tapping 3.Side cover 5 comprises cover plate 5a, header board 5b and parallel-plate 5c.Cover plate 5a extends on the direction substantially vertical with the front surface of column 2, and is configured in this gap location in the mode covering the gap between main tapping 3 and column 2.Cover plate 5a is arranged on the protuberance 3a of main tapping 3, therefore, there is gap hardly between cover plate 5a and protuberance 3a, can prevent cooling fluid from entering from this gap.Header board 5b is outstanding to main tapping 3 side from the leading section of cover plate 5a, and parallel with the front surface of column 2.Parallel-plate 5c is outstanding to the side (direction away from main tapping 3) contrary with side, main tapping 3 place from the rearward end of cover plate 5a, and parallel with the front surface of column 2.
The front surface of column 2 is located at by the relative plate 30 (first-phase to plate) relative with parallel-plate 5c.Relative plate 30 is almost parallel with parallel-plate 5c.Between relative plate 30 and parallel-plate 5c, there is less gap.Relative plate 30 size is in the lateral direction greater than parallel-plate 5c size in the lateral direction.Projecting plate 31 from relative plate 30 by main tapping 3 side (left side in Fig. 4) edge forwards (direction away from column 2) give prominence to.The outstanding length of projecting plate 31 is greater than the gap between relative plate 30 and parallel-plate 5c.The edge by main tapping 3 side of relative plate 30 is positioned at than the position of cover plate 5a by main tapping 3 side.When cooling fluid enters between relative plate 30 and parallel-plate 5c, the direct of travel of cooling fluid can be changed to front by projecting plate 31.Therefore, cooling fluid can not be attached to Z axis guide rail 20 and sliding part 21.
Side cover 5 is located at main tapping 3, therefore, compared with lathe in the past, work holding portion thereof 10 can be made near rear side (column 2 side), its amount near rear side and side cover 5 width suitable.Reason is, by with side cover suitable component be located on column 2 time, covering suitable component with side needs to configure in the mode of the scope that moves up and down spreading all over main tapping 3.In this case, in order to make the lower end of covering suitable component with side can not encounter work holding portion thereof 10, and need work holding portion thereof 10 to be configured in the position by away from the side of column 2.Therefore, 5 be located on main tapping 3 by side cover in the present embodiment, therefore, main tapping 3 can be positioned at the position of side rearward, and the amount of its side is rearward the amount of work holding portion thereof 10 near column 2 side.Therefore, this lathe can prevent main tapping 3 from increasing away from the amount of column 2.
When cooling fluid is between parallel-plate 5c with relative plate 30, projecting plate 31 prevents entering of cooling fluid, thus prevents cooling fluid to be attached to Z axis guide rail 20 and sliding part 21.
Below, according to representing that the accompanying drawing of the lathe after the part in structure being changed is described this lathe.Fig. 5 is the enlarged partial sectional view of lathe.Fig. 5 and Fig. 4 is corresponding.
The preventing board 50 entered for preventing cooling fluid is outstanding to main tapping 3 side (left side in Fig. 5) from the rearward end of cover plate 5a.Preventing board 50 is the plate of the lengthwise being word master L-shape when overlooking.Preventing board 50 comprises header board portion 51 (plate portion) and barrier plate portion 52.Header board portion 51 at cover plate 5a by the position of column 2 side, parallel with parallel-plate 5c and outstanding to main tapping 3 side.The nose portion of barrier plate portion 52 from header board portion 51 rearward (column 2 side) is given prominence to, and it can stop cooling fluid to enter.The top in barrier plate portion 52 is close to relative plate 30a (second-phase is to plate).When cooling fluid is between parallel-plate 5c with relative plate 30a, preventing board 50 prevents entering of cooling fluid, thus prevents cooling fluid to be attached to Z axis guide rail 20 and sliding part 21.
Relative plate 30a does not arrange projecting plate 31, but, also projecting plate 31 can be set on relative plate 30a.When projecting plate 31 being located at right side or the left side in barrier plate portion 52, cooling fluid can be made to be difficult to be attached to Z axis guide rail 20 and sliding part 21.
Also relative plate 30 and projecting plate 31 can not be set at column 2.As long as side cover 5 is installed on main tapping 3 by producer, thus can simplify manufacturing process.Projecting plate 31 also can be configured in end than parallel-plate 5c by away from the position of the side of main tapping 3.Projecting plate 31 also can be configured in the pars intermedia of relative plate 30, but not the end of relative version 30.
