Description
Technical field
The utility model relates to without friction Pneumatic Cylinder with Friction fields of measurement.
Technical background
Along with the development of gas lubrication technology, gas suspension is widely used without friction system.As a kind of gas suspension without the friction cylinder, leave minimum gap between cylinder barrel and piston, and the throttle orifice of even distribution is set on piston radial, pressurized air in employing cylinder self cavity volume is as lubricant, gas is introduced in the gap, make piston be in complete suspended state in cylinder, piston does not contact each other with cylinder barrel, thereby has eliminated the friction force between piston and cylinder barrel in the air cylinder structure.
Gas suspension has very high processing requirement on machining accuracy without the friction cylinder, guarantee that the gap of piston and cylinder barrel is in the machining precision error range that allows, to carry out the check of friction force, the quality testing when dispatching from the factory such as finished product to manufactured gas suspension without the friction cylinder.Because gas suspension is minimum without the friction force of friction cylinder between when work and cylinder barrel, basically only there is air resistance, if there is micro-wiping between piston and cylinder barrel, friction force is also minimum, can't obtain result accurately with common friction measurement device.
Summary of the invention
In order to overcome the deficiency that can't accurately obtain the minimum friction force that gas suspension exists without friction cylinder barrel and piston space in prior art, the utility model provide a kind of convenient test, degree of accuracy high without the Pneumatic Cylinder with Friction measurement mechanism that rubs.
The technical scheme that its technical matters that solves the utility model adopts is:
a kind of without friction Pneumatic Cylinder with Friction proving installation, comprise test platform, regulating device in order to the height of regulating test platform, laser displacement sensor and disk baffle, described laser displacement sensor coordinates with described disk baffle, be fixedly connected with between described piston rod and the standard piston rod end without the cylinder that rubs without the friction cylinder to be tested, in described fixed connection place, described disk baffle is installed, described nothing friction cylinder to be tested and described standard all are fixed on test platform without the friction cylinder, described laser displacement sensor is fixed on test platform, described test platform one end is hinged on pedestal, described regulating device is arranged on the opposite side of test platform, described two air intake openings without the friction cylinder all are communicated with same source of the gas.
Further, described piston rod and standard without the friction cylinder to be tested passed through the anchor ear distich without the piston rod of friction cylinder, described anchor ear is set with the disk plate washer outward; Certainly, also can be fixedly connected with by other web members, perhaps directly be fixedly connected with.
Further again, described test platform one end is connected with pedestal by hinge.Also can select other articulated manner.
Described nothing friction cylinder to be tested and described standard all are fixed on test platform by cushion block without the friction cylinder, and described laser displacement sensor is fixed on test platform by holder.
technical conceive of the present utility model is: with two without friction cylinder distiches and being fixed on the test platform of level, adopt same gas source feed to make the piston of two cylinders be in equilibrium state, then adjust the height of test platform, utilize the weight component without friction cylinder piston and piston rod to overcome frictional resistance, piston is during by static setting in motion, be set with disk baffle outside anchor ear, disk baffle moves with piston, can accurately measure the displacement variable of unit interval inner carrier by laser displacement sensor, because the laser displacement sensor precision is high, fast response time, can accurately obtain the size of piston movement brief acceleration, by measuring the length of test platform when the horizontality and the height of its deflection, according to the equilibrium of forces principle, the size of force of sliding friction in the time of just can calculating piston and be in certain position and between cylinder barrel.
Because test platform deflection angle in test process is less, in order to obtain more accurate measured value, the length dimension of test platform is much larger than the length value without the friction cylinder.
The beneficial effects of the utility model are mainly manifested in: convenient test, degree of accuracy are high.
