Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Consult Fig. 3, Fig. 4, and Fig. 5, the preferred embodiment that the utility model supports damping device is installed in a toolroom machine 3.Two axle beds 32, spiral shells that described toolroom machine 3 has a worktable 31, be formed on described worktable 31 1 bottom surfaces and the spacing of being separated by are worn a ball screw 33 of described axle bed 32, and are formed on two pairs of protuberances 34 of described axle bed 32 both sides.Described support damping device comprises a pedestal 4, a support group 5, four elastic components 6, and two cushion dashpots 7.
Described pedestal 4 is arranged on described worktable 31 belows.
Described support group 5 has a microscope carrier 51 that mounts above described pedestal 4, reaches two abrasion performance bodies 52 that are hubbed on described microscope carrier 51 side by side and are positioned at described ball screw 31 both sides.
Aforementioned elastic component 6 is arranged on 51 of described pedestal 4 and described microscope carriers.
Because described ball screw 33 passes through top of the present utility model, therefore, when described worktable 31 is followed described ball screw 33 displacements, and aforementioned axle bed 32 is not during by described support group 5, described microscope carrier 51 can be subjected to the elastic force effect of aforementioned elastic component 6, and the aforementioned abrasion performance body 52 of interlock moves to the described ball screw 3 of support and is positioned at a primary importance to rising.Whereby, with described microscope carrier 51 and aforementioned abrasion performance body 52, reach the purpose that supports described ball screw 33.
