Abstract
The double action cylinder loading test device includes double action cylinders and a hydraulic loop. It has two double action cylinders, including one loading cylinder and one tested cylinder, connected to the hydraulic pipeline. The swinging arm is hinged to the first fixing rack in the eccentricity A; the loading cylinder is hinged to the second fixing rack and its piston rod is hinged to one end of the swinging arm; and the tested cylinder is hinged to the other end of the swinging arm and its piston rod is hinged to the third fixing rack. The present invention has low manufacture cost and can simplify the cylinder loading test and raise the work efficiency.
Description
Technical field
The present invention relates to a kind of testing apparatus, especially relate to a kind of two-way cylinder that is used for and load the testing apparatus that detects.
Background technique
At present, load test to two-way cylinder in the industry adopts standard GB/T15622-1995 oil hydraulic cylinder test method (" engineering machinery important spare part standard compilation " edited and publish at national project mechanical quality supervision and inspection center) more, this standard discloses the loading tester device of two-way cylinder as shown in Figure 1, but this testing apparatus has adopted two oil hydraulic circuits, complex structure, and manufacture cost height.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of technology of simple and effective double action cylinder loading test device.
Technical problem to be solved by this invention is achieved by the following technical solution: it comprises two-way cylinder, oil hydraulic circuit, this device has two two-way cylinders, one is load cylinder, another is tested oil cylinder, the two ends of load cylinder and tested oil cylinder are connected hydraulic pipe line respectively, and swing arm is installed on the fixed support by hinge, the eccentric A of swing arm, the cylinder body of load cylinder is installed on the fixed support by hinge, and piston rod is installed in swing arm one end by hinge; The cylinder body of tested oil cylinder is installed in the swing arm the other end by hinge, and piston rod is installed on the fixed support by hinge.
The said structure that the present invention adopts has reduced the manufacture cost of double action cylinder loading test device, makes the double action cylinder loading test technology more easy, and has improved working efficiency.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Figure 1 shows that the schematic diagram of existing double action cylinder loading test device
Figure 2 shows that the schematic diagram of double action cylinder loading test device of the present invention
Embodiment
As shown in Figure 2, this device has two two-way cylinders, one is load cylinder 8, another is tested oil cylinder 9, the two ends of load cylinder 8 and tested oil cylinder 9 are connected hydraulic pipe line respectively, and swing arm 10 is installed on the fixed support 11 by hinge, the eccentric A of swing arm, the cylinder body of load cylinder 8 is installed on the fixed support 12 by hinge, and piston rod is installed in swing arm 10 1 ends by hinge; The cylinder body of tested oil cylinder 9 is installed in swing arm 10 the other ends by hinge, and piston rod is installed on the fixed support 13 by hinge.When solenoid valve is in right-hand member, imported the hydraulic oil of uniform pressure at rodless cavity one end of load cylinder 8 and tested oil cylinder 9, the active force that two oil cylinders act on swing arm 10 two ends is identical, because the eccentric A of swing arm, make the arm of force of measured oil cylinder end greater than the arm of force of load cylinder end, thereby the moment of measured oil cylinder end is greater than the moment of load cylinder end, and swing arm 10 clockwise rotates, and the piston rod of the cylinder body of tested oil cylinder 9 and load cylinder 8 is done rightabout motion; When the solenoid valve commutation is in left end, imported the hydraulic oil of uniform pressure at rod chamber one end of load cylinder 8 and tested oil cylinder 9, because swing arm 10 eccentric A, the moment of measured oil cylinder end is greater than the moment of load cylinder end, swing arm 10 rotates counterclockwise, and the piston rod of the cylinder body of tested oil cylinder 9 and load cylinder 8 is done rightabout motion.By the commutation of control electromagnetic valve, make the cylinder body of tested oil cylinder 9 do the to-and-fro motion go round and begin again, realize load test to two-way cylinder.Oil hydraulic circuit of the present invention can be made up of oil purifier 1, oil hydraulic pump 2, relief valve 3, one-way valve 4, solenoid directional control valve 5 and pipeline, and two output terminals of solenoid directional control valve 5 are connected to load cylinder 8 and tested oil cylinder 9 by two pipelines respectively.In addition, the present invention can be equipped with pressure gauge 6,7 connecting on the pipeline of solenoid directional control valve 5 and two-way cylinder, and the numerical value change from the pressure gauge can reflect the test parameters of two-way cylinder.
