Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is further elaborated.
Embodiment 1
As shown in Figure 1, the utility model embodiment has proposed a kind of isolation mounting, comprises power set 1, leading screw 2, mother lead screw 3, slide carriage 5, nut seat 4, connecting rod 6, rear end rod end ball bearing 7, front end rod end ball bearing 11 and base plate 9;
Nut seat 4 is all positioned on base plate 9 with slide carriage 5; Power set 1 are connected with leading screw 2 and drive leading screw 2 to rotate; Mother lead screw 3 is spirally connected with leading screw 2; Nut seat 4 is enclosed within the outside of mother lead screw 3; Slide carriage 5 is positioned at leading screw 2 one end away from power set 1, and its inside is provided with cavity 12; Slide carriage is provided with the first opening communicating with cavity 12 towards a side of power set 1; Rear end rod end ball bearing 7 and front end rod end ball bearing 11 are connected to the two ends of connecting rod 6, and rear end rod end ball bearing 7 is fixed in cavity 12, and front end rod end ball bearing 7 is fixed on the side of nut seat 4 towards slide carriage 5.
By technique scheme, can make to become indirect connection with the direct-connected slide carriage 5 of nut seat 4 in prior art.The vibration that leading screw 2 produces in rotation process is passed to after nut seat 4, can further be passed on rear end rod end ball bearing 7.In the process that is passed to connecting rod 6 by front end rod end ball bearing 11, can eliminate a part.Vibrate afterwards in the process that is passed to rear end rod end ball bearing 7 by connecting rod 6 and also can eliminate a part.After twice elimination, the vibration force that is passed to slide carriage 5 can significantly reduce, and what therefore slide carriage 5 can move is more steady, thereby improves the surface accuracy of machine components processing.
In an embodiment of the present utility model, preferably, on base plate 9, be provided with the axially extended guide rail 10 along leading screw 2; The bottom of nut seat 4 and guide rail 10 are slidably connected.Can further limit nut seat 4 by guide rail 10 like this, what make that slide carriage 5 moves is more steady.
In an embodiment of the present utility model, preferably, leading screw 2 stretches into cavity 12 away from one end of power set 1.Can reduce like this volume of whole isolation mounting, save space, cavity 12 also can play the effect of leading for leading screw 2 simultaneously.
In an embodiment of the present utility model, preferably, also comprise connecting plate 8; Slide carriage 5 is provided with the second opening communicating with cavity 12 away from a side of power set 1; Connecting plate 8 is removably connected with slide carriage 5 and covers the second opening.Because rear end rod end ball bearing 7 is arranged on cavity 12 inside, and general distance the first opening is far away, and maintenance and replacing are all very inconvenient, therefore can carry out maintenance activity to rear end rod end ball bearing 7 more easily by connecting plate 8 is set.
In an embodiment of the present utility model, preferably, rear end rod end ball bearing 7 can directly be fixed on connecting plate 8, and opening like this connecting plate 8 afterwards just can be directly right.Rear end rod end ball bearing 7 keeps in repair.
In an embodiment of the present utility model, preferably, rear end rod end ball bearing 7 is provided with a fixed part through connecting plate 8; The part of fixed position outside cavity 12 locked by locking member 13.Wherein, locking member 13 can be selected nut, and screw thread is set on fixed part to complete fixing with the mode of nut threaded.This structure is comparatively simple, dismantles also very easy.
In an embodiment of the present utility model, preferably, rear end rod end ball bearing 7 and front end rod end ball bearing 7 being axially oppositely arranged along leading screw 2.Can ensure like this in transmission process, except vibration force, substantially not produce unnecessary component consumption of power, more energy-conservation.
In an embodiment of the present utility model, preferably, between nut seat 4 and power set, be provided with bearing block 14; Leading screw 2 passes bearing block 14 and is mated.Can further reduce like this vibration of leading screw 2.
In an embodiment of the present utility model, alternatively, leading screw 2 can have multiple arrangement mode with the axis of connecting rod 6, but because the integral thickness of slide carriage 5 is thinner, therefore the axis of preferred leading screw 2 and connecting rod 6 is along horizontal plane parallel arrangement.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that, in the situation that not departing from principle of the present utility model and aim, can carry out multiple variation, amendment, replacement and modification to these embodiment, scope of the present utility model is limited by claim and equivalent thereof.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of the each embodiment technical scheme of the utility model.
