The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing.
Referring to Fig. 1, the figure shows the unsteady jig structure that the embodiment of the invention provides.For the ease of explanation, only show the part relevant with the embodiment of the invention.
The said a kind of unsteady jig of the embodiment of the invention comprises that the floating disc 5, that driven by machine tool hydraulic bar 9 is installed in location-plate 2 and on the lathe datum plate 1 and is located at the connecting plate that is connected lathe hydraulic stem 93 between said location-plate 2 and the datum plate 1; Between said connecting plate 3 and said location-plate 2, be provided with the floating space 10 of said floating disc; Said floating disc 5 is a disk, and central authorities establish the hole, its inner circumferential surface be provided with can said relatively circumferential surface claw 6 in axial sliding, said claw 6 bottoms connect said location-plate 2 through back-moving spring; Said floating disc 5 left sides contact with said location-plate 2 right sides and are connected through the alignment pin 7 on the said location-plate 2, the connector 4 that passes on the said location-plate 2.
Described claw 6 is three, is installed in three T type chutes that said floating disc 5 inner circumferential surfaces evenly offer.Corresponding, described alignment pin 7 is three, is installed on the described location-plate 2 through three-point fox method.
Described connector 4 comprises the screwed pipe 42 that a screw rod 41 and described screw rod 41 are fixedly connected, and said screw rod 41 is installed on the said connecting plate 3, and said screwed pipe 42 is fixed on the described floating disc 5.After being fixedly connected through described screw rod 41, screwed pipe 42, described connecting plate 3 is fixedly connected with said floating disc 5.
Described location-plate 5 is provided with and is used for the through hole 20 that described connector 4 passes.
Described back-moving spring is located in the spring eye of on institute's rheme plate, offering 8.
Described datum plate 1 is installed on the machine tool chief axis; Through being located at the connecting plate 3 between described datum plate 1 and the location-plate 2; Be fixedly connected with the hydraulic stem 9 of machine tool chief axis and transmit action, and through the through hole 20 on the location-plate 1, the connector 4 that is located in the said through hole 20 connects with floating disc 5.
