Description
Technical field
This utility model relates to nitrogen balance system, particularly relates to the nitrogen balance cylinder of nitrogen balance system.
Background technology
The nitrogen balance system of lathe class machining center, instead of traditional main shaft balancing weight counterweight, had both decreased raw-material resource loss, reduced the gross weight of lathe, also reduces the microseismic activity that motion of main shaft produces simultaneously, improves Product Precision.
At present, nitrogen balance cylinder in nitrogen balance system has the features such as little, the energy-conservation energy of volume, but, the acoustic filter of existing nitrogen balance cylinder mostly is external structure, and aqueous vapor in external environment condition, mist of oil, dust are more so that the service life of acoustic filter is greatly shortened, in addition, the acoustic filter noise reduction of existing nitrogen balance cylinder is poor, thus, is badly in need of solving.
Utility model content
The purpose of this utility model is in that for the problems referred to above, it is provided that a kind of nitrogen balance cylinder, and the acoustic filter to solve existing nitrogen balance cylinder is short for service life, the problem of noise reduction difference.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of nitrogen balance cylinder, including cylinder body, end cap and acoustic filter, described end cap has installing hole, extremely it is followed successively by bottom outlet outward, for fixing locking hole and the counterbore of acoustic filter in described installing hole, described bottom outlet is connected with the endoporus of end cap, described acoustic filter is made up of the first noise elimination portion matched with locking hole and the second noise elimination portion matched with counterbore, described first noise elimination portion has inlet channel, noise reduction chamber in described inlet channel and the second noise elimination portion is connected, and the outlet side in described second noise elimination portion has several bloops.
As a kind of preferred version of the present utility model, described locking hole is screwed hole, and the outer wall in the first noise elimination portion of described acoustic filter is provided with the external screw thread matched with locking hole.
As a kind of preferred version of the present utility model, described silencing cavity indoor are provided with quieter material.
As a kind of preferred version of the present utility model, described quieter material is super glass wool.
As a kind of preferred version of the present utility model, the aperture of described bloop is 1mm.
The beneficial effects of the utility model are, described a kind of nitrogen balance cylinder is by offering bottom outlet, locking hole, counterbore, acoustic filter is built in end cap, not only easy for installation, simple, and effectively prevent aqueous vapor, mist of oil, dust from entering in acoustic filter, improve the cleannes of acoustic filter, extend the service life of acoustic filter; Additionally, acoustic filter of the present utility model has the feature of simple in construction, excellent noise reduction effect.

Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention. It is understood that embodiment described herein is used only for explaining this utility model, but not to restriction of the present utility model.
Refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the structural representation of a kind of nitrogen balance cylinder of this utility model; Fig. 2 is the enlarged drawing at A place of a kind of nitrogen balance cylinder shown in Fig. 1.
In the present embodiment, a kind of nitrogen balance cylinder, including cylinder body 1, end cap 2 and acoustic filter, described end cap 2 has installing hole, to being followed successively by outward bottom outlet 3 in described installing hole, for fixing locking hole 4 and the counterbore 5 of acoustic filter, described bottom outlet 3 is connected with the endoporus 6 of end cap 2, described acoustic filter is made up of the first noise elimination portion 7 matched with locking hole 4 and the second noise elimination portion 8 matched with counterbore 5, described locking hole 4 is screwed hole, the outer wall in the first noise elimination portion 7 of described acoustic filter is provided with the external screw thread matched with locking hole 4, described first noise elimination portion 7 has inlet channel 9, described inlet channel 9 is connected with the noise reduction chamber in the second noise elimination portion 8, described silencing cavity indoor are provided with quieter material, described quieter material is super glass wool, the outlet side in described second noise elimination portion 8 has several bloops, the aperture of described bloop is 1mm.
The acoustic wave filter structure of above-mentioned nitrogen balance cylinder is simple, excellent noise reduction effect, and by being built in end cap 2 by acoustic filter, substantially prolongs its service life, additionally, acoustic filter is threadeded with end cap 2, and convenient disassembly, it is simple to change, safeguard.
Above example simply elaborates ultimate principle of the present utility model and characteristic; this utility model is not limited by above-described embodiment; under the premise without departing from this utility model spirit and scope; this utility model also has various change and change, and these changes and change both fall within the scope of claimed this utility model. This utility model claims scope and is defined by appending claims and equivalent thereof.
