Abstract
The utility model, which is created, provides a kind of cylinder pneumatic counterbalance system, the cylinder set straight down including a piston rod and the brake being correspondingly arranged with the cylinder piston rod, also include and the first supply air line and the second supply air line for being connected with brake that cylinder rod chamber is connected, first supply air line is provided with pressure-reducing valve and air bleeding valve, wherein air bleeding valve is arranged between pressure-reducing valve and cylinder, and second supply air line is provided with a normally closed type two position three-way valve.The utility model creates a kind of described cylinder pneumatic counterbalance system, and by the system control, when detection platform works, the pressure of rod chamber can offset detection platform self gravitation all the time in balance cylinder.Such as run into and die suddenly, power off special circumstances, brake can pin cylinder rod rapidly.Damage will not be caused to ball-screw when ensure that detection platform work, the control that detection platform lifts precision is improved, also so as to ensure that the accurate of testing result.
Description
Technical field
The invention belongs to steel tube supersonic detection technology field, more particularly, to a kind of cylinder air-balance system
System.
Background technology
Current production technology of steel tube both domestic and external relate to the application of pneumatic principle.But due to detection platform self gravitation compared with
Conference causes ball-screw serious wear, reduces leading screw its service life, thus how to design a detection platform balance system into
For new research and development problem.
The content of the invention
In view of this, the invention is directed to a kind of cylinder pneumatic counterbalance system, with the control to detection platform
System, thus reduces the abrasion of ball-screw.
To reach above-mentioned purpose, what the technical scheme of the invention was realized in：
A kind of cylinder pneumatic counterbalance system, including the cylinder that sets straight down of a piston rod and with the cylinder piston rod
The brake being correspondingly arranged, in addition to the first supply air line connected with cylinder rod chamber and the second supply connected with brake
Pipeline, first supply air line is provided with pressure-reducing valve and air bleeding valve, and wherein air bleeding valve is arranged between pressure-reducing valve and cylinder, and described the
Two supply air lines are provided with a normally closed type two position three-way valve.
Further, the air bleeding valve is provided with muffler.
Further, the cylinder rodless cavity gas outlet is connected with muffler.
Relative to prior art, a kind of cylinder described in the invention is had the advantage that with pneumatic counterbalance system：
A kind of cylinder pneumatic counterbalance system described in the invention, by the system control, when detection platform work
When, the pressure of rod chamber can offset detection platform self gravitation all the time in balance cylinder.Such as run into die suddenly, power off it is special
Situation, brake can pin cylinder rod rapidly.Damage will not be caused to ball-screw when ensure that detection platform work, is improved
Detection platform lifts the control of precision, also so as to ensure that the accuracy of testing result.

State concrete meaning of the term in the invention.
Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, a kind of cylinder pneumatic counterbalance system, including the cylinder 6 that sets straight down of a piston rod and with
The brake 7 that the piston rod of cylinder 6 is correspondingly arranged, in addition to the first supply air line for being connected with the rod chamber of cylinder 6 and with braking
The second supply air line that device 7 is connected, first supply air line is provided with pressure-reducing valve 1 and air bleeding valve 2, and the air bleeding valve 2 is provided with
Muffler 3, wherein air bleeding valve 2 are arranged between pressure-reducing valve 1 and cylinder 6, and second supply air line is provided with a normally closed type two three
The pneumatic member on pneumatic member, the second supply air line on port valve 5, the first supply air line is formed by connecting into by pipeline 4 respectively.
In the present embodiment, the cylinder rodless cavity gas outlet is connected with muffler.
The present embodiment specific work process is：Detection platform is arranged on cylinder piston rod bottom, the first supply air line and
Two supply air lines are imposed upward active force, therefore detection platform by cylinder all in aeration status all the time, thus detection platform
The pressure of leading screw is reduced, therefore reduces the infringement to leading screw, the service life of leading screw is extended.When normally closed type two-position three way
Valve 5 power off when, the gas circuit of normally closed type two position three-way valve 5 disconnect, brake at once hold tightly cylinder piston rod, prevent cylinder piston rod after
Continuous to move down, the same gravity for ensureing detection platform itself is not acted on leading screw all, therefore reduces the infringement to leading screw.
The preferred embodiment of the invention is the foregoing is only, creation is not intended to limit the invention, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc. should be included in the invention
Protection domain within.
