Background technology
Linear bearing is widely used in plant equipment, the flexibility ratio of linear bearing has large effect to the performance of plant equipment, particularly when linear bearing is used in pairs, the concordance (or claiming difference) of its flexibility ratio has bigger impact to the performance of plant equipment.Generally we check flexibility ratio to be the perception experience by reviewer, and the most whether standard Relative Fuzzy does not has the standard of a kind of quantization to weigh and describe concrete degree of flexibility, and the concordance of assembling cannot ensure.When using the most in pairs, the apolegamy to flexibility ratio is consistent is difficult to carry out and ensures.
Summary of the invention
The purpose of this utility model a kind of linear bearing flexibility ratio detection device that can quantify for the weak point in the presence of above-mentioned prior art just.
Device of the present utility model promotes linear bearing guide pillar to make uniform motion along the linear bearing guide pin bushing fixed by driving means, placement force sensor between linear bearing guide pillar and driving means, read by computer and store the pressure between linear bearing guide pillar and driving means, using this force value as the damping weighing linear bearing.Force value is the least, illustrates that flexibility ratio is the highest.In actual production, this value available is as selecting and apolegamy linear bearing.
The purpose of this utility model can be realized by following concrete technical measures:
Linear bearing flexibility ratio of the present utility model detection device includes, for promoting linear bearing guide pillar at the uniform velocity steadily along the linear drive apparatus of the guide bush movement being installed with linear bearing, being arranged on the pressure transducer on linear bearing guide pillar;Described pressure transducer is connected with the corresponding interface of computer by data wire;Combine with dynamic fit system between described linear bearing guide pillar and linear bearing;Described guide pin bushing and linear drive apparatus are arranged on stationary work-table by fixing connector respectively.
Linear drive apparatus described in this utility model is that the feed screw nut using reducing motor to drive produces mechanism's composition, i.e. drives feed screw nut to produce steady linear uniform motion by reducing motor.
Operation principle of the present utility model is as follows:
During detection, promote linear bearing guide pillar at the uniform velocity steadily edge to be installed with the guide bush movement of linear bearing by driving means, measure the pressure between driving means and linear bearing guide pillar by pressure transducer, using this force value as the damping weighing linear bearing.Connect computer by data wire data stored and show simultaneously.
The beneficial effects of the utility model are as follows:
1, compact conformation, easy to operate.
2, use pressure transducer and computer data acquiring, accurate results can be obtained.
Detailed description of the invention
This utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1: linear bearing flexibility ratio of the present utility model detection device includes for promoting linear bearing guide pillar 5 at the uniform velocity steadily along being installed with the linear drive apparatus 1 that the guide pin bushing 6 of linear bearing moves, the pressure transducer 4 being arranged on linear bearing guide pillar 5;Described pressure transducer 4 is connected by the corresponding interface of data wire 3 with computer 2;Combine with dynamic fit system between described linear bearing guide pillar 5 and linear bearing;Described guide pin bushing 6 and linear drive apparatus 1 are arranged on stationary work-table by fixing connector respectively.
Linear drive apparatus 1 described in this utility model is that the feed screw nut using reducing motor to drive produces mechanism's composition, i.e. drives feed screw nut to produce steady linear uniform motion by reducing motor.
