Specific embodiment
As shown in Figure 1 and Figure 2, a kind of turning attachment that fan-shaped balance weight part is processed on vertical lathe, is made up of rotating disk 1, spacer pin 2, supporting screw 3, hold-down gear 4, rotating disk mounting screw 5, slide block device 6.Rotating disk 1 is fixed on machine tool chief axis by rotating disk mounting screw 5；Spacer pin 2, supporting screw 3, hold-down gear 4, slide block device 6 are arranged on and turn on 1 disk.
The rotating disk 1 is in the form of annular discs, the parts such as disk limited location pin 2 installed above, supporting screw 3, hold-down gear 4, rotating disk mounting screw 5, slide block device 6, there is the interface being engaged with machine tool chief axis below, and by rotating disk mounting screw 5, be fixed on machine tool chief axis.
The one end of the spacer pin 2 is inserted in the spacer pin location hole of rotating disk 1, and the other end is located above fan-shaped balance weight in rotating disk.Specifically：During processing balance weight inner arc surface, spacer pin 2 is inserted in boring spacer pin location hole 7 on the turntable 1, and positioning is contacted with the exterior arc surface of fan-shaped balance weight；During processing sector balance weight exterior arc surface, spacer pin 2 is then inserted in turning spacer pin location hole 14 on the turntable 1, and positioning is contacted with the inner arc surface of fan-shaped balance weight.
The supporting screw 3 by being screwed on rotating disk 1, for support workpiece sector balance weight.
As shown in Figure 1, Figure 2, shown in Fig. 4, Fig. 5, the hold-down gear 4 is made up of clamp nut 17, compact heap 18, column 19, and the hypomere of column 19 has mounting disc, is fixed on rotating disk 1 by screw 20, there is one section of smooth cylinder its upper end, there is the screw thread matched with clamp nut 17 in the cylinder upper end.Compact heap 18 is in strip, and there is the unthreaded hole coordinated with column 19 one end, is enclosed within column 19, and can rotate and move up and down on column 19, and the other end is pressed on fan-shaped balance weight；Clamp nut 17 is screwed on column 19 to be used to compress compact heap 18.
As shown in Figure 1, Figure 2, Figure 3 shows, the slide block device 6, is made up of sliding block base 8, slider support screw 9, slide block locating dowel 10, screw rod 11, pad 12, nut 13, sliding block 15, slider nut 16.The slide block locating dowel 10 is hollow cylindrical structure, is installed on sliding block 15 by screw.The outside diameter of slide block locating dowel 10 coordinates with the location hole of fan-shaped balance weight, and endoporus is used to install screw rod 11.
Slider support screw 9 is installed on sliding block, and workpiece is supported together with supporting screw 3.
As shown in Fig. 3, Fig. 6, Fig. 7, Fig. 8, the structure in the form of slot of the sliding block base 8 is provided with longitudinal elongated slot in the plane of groove.The bottom of groove is inclined-plane, and bottom end thickness one end is thin.The thick one end of the bottom land of sliding block base 8 outwards, is installed on rotating disk 1.As shown in Figure 9, Figure 10, sliding block 15 is in strip, there is longitudinal boss below, and the above is plane.Downwards, boss is installed in longitudinal elongated slot of sliding block base 8 boss, and can be slided in groove.
As shown in figure 3, there is screw thread at the two ends of the screw rod 11, it passes through the circular hole in the middle of slide block locating dowel 10 and lower end is stretched out below the groove profile bottom surface of sliding block base 8, and slider nut 16 is provided with external part.The threaded upper ends of screw rod 11 are screwed with nut 13.
As shown in figure 3, the slider nut 16 is the square nut with inclined-plane.The width of nut is consistent with the groove profile width of sliding block base 8, and the gradient on inclined-plane is consistent with the surface slope of the trench bottom of sliding block base 8.While fan-shaped balance weight is compressed, inclined-plane and the bottom bevel of sliding block base 8 of slider nut 16 are close together.
When present invention assembling is used, fan-shaped balance weight is kept flat on the turntable 1, location hole is enclosed within slide block locating dowel 10, is supported by the supporting screw 9 on supporting screw 3 and sliding block 15.
In lathe external arc surface, locating dowel 3 is inserted into " in the turning location hole " of disk 1 first, then inwardly pushes away fan-shaped balance weight, now fan-shaped balance weight is moved inward together with sliding block 6, mobile completion positioning is stopped when locating dowel 3 is encountered.Finally tighten nut 13, nut 17 and compress fan-shaped balance weight.
In processing excircles cambered surface, alignment pin 2 is extracted from dowel hole, be inserted in " boring location hole ".Nut 13 and nut 17 are unclamped, fan-shaped balance weight is pulled out, fan-shaped balance weight is displaced outwardly together with sliding block 6, mobile completion positioning is stopped when locating dowel 3 is encountered.Tighten nut 13, nut 17 and compress fan-shaped balance weight.After fan-shaped balance weight is compressed, locating dowel 2 is extracted, start size cambered surface.
In turnery processing exterior arc surface due to rotary motion, fan-shaped balance weight and the generation centrifugal force of sliding block 15, fan-shaped balance weight is set to have the trend being displaced outwardly.Because the trench bottom of sliding block base 8 is inclined-plane, and the thick one end of bottom land is outwards installed on rotating disk 1, and the inclined-plane of slider nut 16 is close together with the bottom bevel of sliding block base 8 when fan-shaped balance weight is compressed, so the trend will be stretched screw rod 11, the result is that increasing the thrust of the fan-shaped balance weight of 13 pairs, nut, so as to fan-shaped balance weight is firmly pressed on supporting screw, the fan-shaped balance weight of limitation is displaced outwardly.
