Abstract
The invention discloses a hydraulic element service life tester which comprises a pneumatic three-link piece, wherein one end of the pneumatic three-link piece is connected with an air source, and the other end of the pneumatic three-link piece is connected with an electromagnetic reversing valve; two outlets of the electromagnetic reversing valve are connected to an upper cavity and a lower cavity of an air cylinder respectively; the upper end of a piston is connected with a collision block, and the lower end of the piston is connected with a pressure head; and route switches are respectively arranged on the left upper side and the right lower side of the collision block. The hydraulic element service life tester can accurately do up-and-down reciprocating motion, and has a function of accumulating the motion times of spring and sliding valve type parts, so that the reliability of the performance test of the spring and sliding valve type parts and the work efficiency of a product are improved; and the cost is saved greatly.
Description
Technical field
The present invention relates to spring, guiding valve class part testing technical field, specifically belong to a kind of Hydraulic Elements life test machine.
Background technology
A kind of Hydraulic Elements life test machine is special test spring, the instrument in guiding valve class part (such as hydraulic parts such as spool, valve rods) life-span.After spring, guiding valve class part (such as hydraulic parts such as spool, valve rods) are produced; Before using; To just can come into operation through the test of strictness; Because spring, guiding valve class part (such as hydraulic parts such as spool, valve rods) majority are to use the main parts size on engineering machinery, vehicle etc., and if mounted in a vehicle spring, guiding valve class part (such as hydraulic parts such as spool, valve rods) do not pass through strict test, just be contained in vehicles to use; Performance does not reach requirement, and that just causes very serious consequence easily; And be used for spring, the guiding valve class part (such as hydraulic parts such as spool, valve rods) of shock-absorbing for another example, because the decline of performance makes and the vehicle out of trim causes traffic hazard easily.The test that this shows spring, guiding valve class part (such as hydraulic parts such as spool, valve rods) has more important.And the structure of present a kind of Hydraulic Elements life test machine is too backward; And it is with high costs; Can not satisfy the production requirement of reality, that quality and the life-span that especially is applied in spring on the engineering machinery, guiding valve class part almost do not have at home is qualified, testing tool can satisfy and produces and needs that product is used cheaply.
Summary of the invention
The purpose of this invention is to provide a kind of Hydraulic Elements life test machine; Can accurately realize pumping; The function that has accumulative total spring, guiding valve class part movement number of times simultaneously; Thereby realize the monitoring of life of product, improved the work efficiency of reliability, stability and product of the performance test of spring, guiding valve class part greatly, and practiced thrift cost greatly.
Technical scheme of the present invention is following:
A kind of Hydraulic Elements life test machine includes pneumatic triple piece, and an end of said pneumatic triple piece is connected with source of the gas; The other end is connected with solenoid directional control valve, and two outlets of solenoid directional control valve are connected respectively in the epicoele, cavity of resorption of cylinder, and the upper end of piston is connected with collision block; The lower end of piston is connected with pressure head; Upper left side, the lower right side of collision block are respectively equipped with travel switch, with the switching-over of control electromagnetic valve, thereby make the cylinder to-and-fro movement.
Be connected with counter on the described travel switch.
The present invention starts through air pump and makes the solenoid directional control valve energising, and Pneumatic pipe cleaner is crossed pneumatic triple piece, solenoid directional control valve gets into the epicoele of cylinder, and makes piston rod descending; Pressure head moves downward to detected element and loads simultaneously; After collision block moves downward the travel switch of running into the lower right side, solenoid directional control valve outage and switching-over, this moment, Pneumatic pipe cleaner was crossed in the cavity of resorption of pneumatic triple piece, solenoid directional control valve entering cylinder; Make the up while pressure head of piston rod upwards unload; When collision block continue to move upward run into the travel switch of upper left side after, above motion is done in solenoid directional control valve energising and switching-over, so goes round and begins again.The present invention can accurately realize pumping; The function that has accumulative total spring, guiding valve class part (such as hydraulic parts such as spool, valve rods) times of exercise simultaneously; Improve the work efficiency of reliability, stability and product of the performance test of spring, guiding valve class part (such as hydraulic parts such as spool, valve rods) greatly, and practiced thrift cost greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
