Abstract
The utility model discloses a rubber vibration isolator comprising a shell (1), a base (3) and a base positioning hole (4), wherein the center position of the shell (1) is provided with a hollow rod (6), and the inner wall of the hollow rod (6) is provided with screw threads (8); a rubber vibration reducing block (2) is fixed on the base (3), and a through hole (5) is arranged in the center of the rubber vibration reducing block (2); and the hollow rod (6) penetrates through the through hole (5) to fix the shell (1) on the rubber vibration reducing block (2). The utility model enhances the machining accuracy because a product provided by the utility model can be fixed on the ground, effectively protect the rubber vibration reducing block (2) and effectively reduce the vibration and the noises of a machine tool.
Description
Technical field
This book model utility relates to a kind of vibration isolator, particularly relates to a kind of rubber vibration isolator that is used on the lathe.
Background technique
Along with the development of world industry level, to the raising day by day that work efficiency and precision etc. require, numerically-controlled precise machine demand is growing, and the numerically-controlled precise lathe has become the main flow equipment of contemporary machine building industry, and each state is all at develop actively numerically-controlled precise machine at present.Because lathe can produce vibration and noise in work, having influenced machining accuracy has greatly brought very big noise to working environment on the other hand on the one hand, and can cause damage to mill floor.China model utility specification CN201382119Y has announced a kind of lathe Filled Iron for Vibration Damping, because the base block rubber is not set directly to be contacted with ground, block rubber can vibrate together along with machine in lathe work, make block rubber more and more thinner along with vibration can make lathe produce displacement and block rubber and ground generation friction, the thin and thick of the different block rubbers of the friction level at four angles also makes the run-off the straight of lathe working plane can influence machining accuracy like this with regard to difference.
The model utility content
The purpose of this utility model is, provides a kind of and can fix on the ground and can effectively protect the rubber damping piece and can effectively reduce the vibration of lathe and the vibration isolator that noise improves machining accuracy.
In order to solve the problems of the technologies described above, the utility model comprises shell, base, base positioning hole, the central position of shell has hollow stem, hollow stem inwall to be provided with screw thread, the rubber damping piece is fixed on the base, there is a through hole at its center, and hollow stem passes through hole shell is fixed on the rubber damping piece.At the hollow stem inwall screw thread being set is for the object with load-bearing, as: lathes etc. are connected on the shell.The curing of rubber damping piece is connected on the base.
In the aforesaid rubber vibration isolator, base is for square and be provided with 2～4 base positioning holes on base.The base positioning hole is set can avoid lathe reason owing to vibration when work to produce displacement with bolt firm the fixing on the ground of base.
In the aforesaid rubber vibration isolator, base is rhombus and is provided with 2～4 base positioning holes on base.
In the aforesaid rubber vibration isolator, hollow stem has a groove near on the outer wall of bottom.At jump ring of installation on the groove shell is fixed on the rubber damping piece.
Compared with prior art, the product that the utility model provides has improved machining accuracy owing to can fix on the ground and can effectively protect the rubber damping piece and can effectively reduce the vibration of lathe and the noise that sends.

Being labeled as in the accompanying drawing: 1-shell, 2-rubber damping piece, 3-base, 4-base positioning hole, 5-through hole, 6-hollow stem, 7-groove, 8-screw thread.
Embodiment
Below in conjunction with drawings and Examples rubber vibration isolator of the present utility model is described in further detail.
Embodiment 1 of the present utility model: its structure as shown in Figure 1, rubber vibration isolator comprises shell 1, base 3, base positioning hole 4, the central position of metal shell 1 has hollow stem 6, hollow stem 6 inwalls to be provided with screw thread 8, rubber damping piece 2 is fixed on the metallic base 3, there is a through hole 5 at its center, and hollow stem 6 passes through hole 5 shell 1 is fixed on the rubber damping piece 2.The base 3 of this product is for square and be provided with 2 base positioning holes 4 on base 3; Hollow stem 6 has a groove 7 near on the outer wall of bottom.
Embodiment 2 of the present utility model: its structure as shown in Figure 1, rubber vibration isolator comprises shell 1, base 3, base positioning hole 4, the central position of metal shell 1 has hollow stem 6, hollow stem 6 inwalls to be provided with screw thread 8, rubber damping piece 2 is fixed on the metallic base 3, there is a through hole 5 at its center, and hollow stem 6 passes through hole 5 shell 1 is fixed on the rubber damping piece 2.The base 3 of this product is for square and be provided with 4 base positioning holes 4 on base 3; Hollow stem 6 has a groove 7 near on the outer wall of bottom.
Working principle of the present utility model: lathe connects screw thread 8 in the hollow stem 6 on the shell 1, lathe is fixed on the shell 1 by bolt; Jump ring is stuck on the groove 7 of hollow stem 6 lower ends also has rubber damping piece 2 to be fixed together on shell 1 and base 3, the base 3 of rubber vibration isolator by bolt on the ground, vibration is absorbed by rubber damping piece 2 when lathe is vibrative, thereby reduced noise, thereby base 3 is fixed and makes lathe can not produce displacement and increased machining accuracy on the ground in vibration.
