Description
Technical field
The utility model relates to a kind of test stand being applicable to the type approval test of various oil hydraulic cylinder and the oil cylinder of reliability trial.
Background technique
Existing conventional cylinder bed stand structure is being carried out in pattern test, reliability trial, just simple utilization loads cylinder as load, tested cylinder level under working pressure is stretched out, tested cylinder is tested in very good situation, therefore cannot reflect the practical working situation of tested cylinder on complete machine.
Model utility content
The purpose of this utility model is just to provide one can carry out omnibearing testing inspection at test stand to oil hydraulic cylinder, and simulated solution cylinder pressure is at the actual conditions of complete machine.Simulate by frock setting height(from bottom) difference and the adjustment of pad the angle and stressed change and lateral load that oil hydraulic cylinder bears at complete machine, the tested cylinder of true reflection is at the test stand of the oil cylinder of the dynamic state of run of complete machine.
Solution of the present utility model is such:
A kind of test stand of oil cylinder, a pair base that fixed intervals are arranged on stand platform, described base is a hinged tested hydraulic cylinder respectively, the tache motorice of tested hydraulic cylinder is hinged with center connection guide rail respectively, described center connection guide rail and stand platform adopt sliding pair anatomical connectivity, and described center connection guide rail slides on described stand platform.
Technological scheme also comprises more specifically: described tested hydraulic cylinder is installed as the structure of fixed end higher than tache motorice.
Further: the structure that the upper surface that described center connection guide rail is stand platform with stand platform seed collecting sliding pair structure directly contacts with the bottom surface of center connection guide rail.
Further: described center connection guide rail and stand platform seed collecting sliding pair structure are that the upper surface of stand platform adjusts substructure height, in order to adjust the angle of oil hydraulic cylinder and stand platform.
Further: described center connection guide rail and tested hydraulic cylinder hinged place are provided with center pad, in order to adjust the gap of tested hydraulic cylinder and center connection guide rail bar head.Base and tested hydraulic cylinder hinged place are provided with base pad, in order to adjust the gap of tested hydraulic cylinder cylinder head and base.
Further: the face that described stand platform slides for center connection guide rail is plane or the arc shaped surface to lower recess.
The utility model has the advantages that and can carry out omnibearing testing inspection at test stand to oil hydraulic cylinder, simulated solution cylinder pressure is at the actual conditions of complete machine.Due to tested cylinder two ends frock height difference, tested cylinder, in running, bears different angles of inclination and different stresses, more truly reflects the dynamic operation situation of oil hydraulic cylinder in complete machine using process.Tested cylinder bears the lateral load that produces of axis disalignment because of two velamens examination cylinders, detects the stability status of the component such as the piston rod of tested cylinder interior, cylinder cap, piston, Sealing.This bed stand reasonable in design, bear the downward with joint efforts of tested cylinder, structure is simple, and cost is low, and reliability is high, is easy to install.Carry out oil hydraulic cylinder test at this bed stand, fully can reflect the real quality state of oil hydraulic cylinder.

Embodiment
As shown in Figure 1, cylinder bench frame comprises the tested oil hydraulic cylinder 7 of center connection guide rail 1, center pad 2, stand platform 3,2# tested hydraulic cylinder 4, hydraulic cylinder mounting base 5, base pad 6 and 1#.All parts are all built on stand platform 3, the upper surface of stand platform 3 directly contacts formation sliding pair with the bottom surface of center connection guide rail 1, earhole is propped up by pinned connection 2# tested hydraulic cylinder 4 and 1# tested hydraulic cylinder 7 in center connection guide rail 1 two ends, the gap of center pad 2 control centre connection guide rail 1 and 2# tested hydraulic cylinder 4 bar head, 2# tested hydraulic cylinder 4 and hydraulic cylinder mounting base 5 earholes pass through pinned connection, the gap of base pad 6 control 2# tested hydraulic cylinder 4 cylinder head and hydraulic cylinder mounting base, hydraulic cylinder mounting base 5 is fixed on stand platform 3.
As shown in Figures 2 and 3,2# tested hydraulic cylinder 4 is back and forth run between two limit positions according to the actual motion speed of complete machine, due to the height difference of center connection guide rail 1 and hydraulic cylinder mounting base 5, tested hydraulic cylinder is in the reciprocatory movement of Derivative limit on the left or on the right position, tested hydraulic cylinder bears different angles of inclination and different stresses, the dynamic operation situation of simulation tested hydraulic cylinder in whole working.Change different two ends tested hydraulic cylinder mounting base 5, the height difference of hydraulic control cylinder mounting base 5 and center connection guide rail 1, the oil hydraulic cylinder making it meet different size is tested.
Shown in Fig. 5, utilize base pad 6 and center pad 4 to control the degree of symmetry of two tested hydraulic cylinder axis, cause the load of tested cylinder and ouput force not on the same axis.In reciprocatory movement, tested hydraulic cylinder bears the lateral load because axis disalignment produces, and reflects the stability status of the component such as the piston rod of tested cylinder interior, cylinder cap, piston, Sealing.
The face that described stand platform 3 slides for center connection guide rail 1 is plane or the arc shaped surface to lower recess.
Above-mentioned explanation is not to reality of the present invention, and the utility model is also not limited to above-mentioned citing, those skilled in the art, the change made, changes and adds or replace in scope of the present utility model, all should belong to protection domain of the present utility model.
