When forming pad 43, pad 43 is contacted with each other, as shown in Fig. 6 B at its proximal end face place with plate 42.For example, pad 43 can have and leader 42C between the corresponding thickness in gap, and be positioned at different upright position on the base part 42A of plate 42, as shown in Fig. 6 C.As shown in Fig. 6 D, can be arranged on plate 42, provide respectively two pads 43 and a pad 43.These two pads 43 are set to the top that a pad is positioned at another pad on a plate 42 therein, form predetermined perpendicular separation between it, and form a pad 43 on another plate 42, and it has and the essentially identical width of top perpendicular separation.In this case, pad 43 is used to make plate 42 appropriately to locate toward each other on the longitudinal direction of guide member 41 as localization part, connects plate 42 afterwards.
Lacertus guide apparatus of the present invention be not limited to therein a vibrator make simultaneously be positioned at two corresponding intervals of spindle in the structure of two guide members, 31,41 vibrations.It also can be provided with like this, make a vibrator make to be positioned at two corresponding intervals of spindle in three or more guide members vibrate simultaneously.For example, a vibrator 37 can make 31 vibrations of four guide members, (has only shown two guide members 31 among the figure) as shown in Figure 7.Vibrator 37 is shaped with respect to carriage 33 horizontal symmetrical ground.Beyond the attaching parts 35,36 except first preferred embodiment, vibrator 37 also is shaped with attaching parts 50.Each attaching parts 50 have and any two adjacent spindles of spinning machine between the corresponding length of spacing distance, and be connected on the attaching parts 35,36, thereby the support section 31C of guide member 31 be clipped in the middle.Note there are not to show guide member 31, vibrating device 39, lead 40A, 40B and the attaching parts 50 that are positioned on attaching parts 36 sides among Fig. 7.The support section 31C of guide member 31 by any suitable method for example solder brazing be connected attaching parts 35,36, on 50.Vibrator 37 vibrates with the resonant frequency (for example about 30kHz) of predetermined guide member 31.This has determined attaching parts 35,36, and 50 shape and diameter make the antinode of extensional vibration of vibrator 37 be positioned at attaching parts 35,36,50 end, and guide member 31 is fixed on the end.By setting like this, guide member 31 carries out bending vibration by attaching parts 35,36 effectively.As apparent from the above description, can further reduce the number of components of Lacertus guide apparatus according to this alternative.Guide member 31 can substitute with guide member 41, and it has two plates 42 that link together by pad 43, and it can be used for substituting guide member 31.
When guide member 31,41 is arranged so that 37 four of the coverings of a vibrator or more a plurality of spindle, carriage 33 can be arranged on the center of vibrator 37, thereby be clipped in the middle by piezoelectric device 34.Alternatively, carriage 33 can be arranged on the extensional vibration node of vibrator 37, and away from piezoelectric device 34.In this case, vibrator 37 can be supported by two carriages 33 being located at two diverse locations, thereby compares more stable with a carriage 33 that is arranged at a position.
The side of leader 42C is not limited to therein the shape of the width (highly) of its upstream side part and downstream part less than the width of core.Alternatively, the side of leader 42C can have wherein width constant shape of substantially constant from upstream to downstream or on whole length.
In the vibration of vibrator 37, attaching parts 35,36, it must be the antinode of extensional vibration that 50 positions that are connected with guide member 31,41 do not need.Alternatively, in attaching parts 35,36,50 and guide member 31,41 between link position can be positioned to antinode away from extensional vibration.Yet guide member 31,41 is arranged so that the antinode of extensional vibration is positioned at guide member 31,41 and attaching parts 35,36, the junction between 40.Therefore, guide member 31,41 can be under required state, by be positioned to compare still less driving energy vibration with being connected therein away from the design of the antinode of extensional vibration.If connect the antinode that is positioned at away from extensional vibration, so in antinode and attaching parts 35,36, the distance between 50 will be littler by 20% than any two adjacent nodes and the distance between the antinode.
Therefore, this example and embodiment are considered to illustrative and not restrictive, and the present invention is not limited to the given details of this paper, and can make amendment within the scope of the appended claims.
