Description
Technical field
The present invention relates to a kind of checkout equipment, be specifically related to a kind of test experience equipment of servo reversing valve.
Background technology
Reversal valve is the directional control valve with two or more liquid form and two or more hydraulic fluid port.Realize the communication of hydraulic oil stream, cut-out and commutation, and the valve that discharge degree and sequentially-operating control.Hand-operated direction valve, solenoid directional control valve, electro-hydraulic reversing valve etc. can be divided into.By the drive transmission device rotating driveshaft outside valve during work, band shakes connecting lever, starts valve plate, leads to the lower part outlet of valve when making working fluid from left entry, time and lead to lower part outlet from right entry conversion, achieve the object that periodic transformation flows to.This change over valve has a wide range of applications in oil, Chemical Manufacture, the most conventional in ammonia system.In addition, reversal valve also can be made the structure of clack type, is used for the occasion compared with low discharge.Handwheel the converts working fluid flow direction by flap only need be rotated during work.
Servo reversing valve is usually used in the hydrostatic control part of automobile, after accepting electric simulation signal, and corresponding output control valve door.In electrohydraulic servo system, electric part and hydraulic part couple together by it, are the cores of electrohydraulic servo system.Due to its design feature, being difficult to find ready-made checkout equipment when detecting and test, needing autonomous Design and innovation.
Summary of the invention
The object of the present invention is to provide a kind of servo reversing valve checkout equipment, can clamp servo reversing valve and fix, and carry out testing or detecting.
For achieving the above object, technical scheme of the present invention is: servo reversing valve checkout equipment, comprise and be arranged on clamping device on base and reciprocating mechanism, described clamping device comprises the bearing be fixed on base, described bearing is provided with the fixture of clamping servo reversing valve, described reciprocating mechanism comprises a rotating shaft be connected with servo reversing valve, rotating shaft is fixedly installed a reciprocal swing arm, the two ends of described reciprocal swing arm have been symmetrical arranged two reciprocating drive units, described reciprocating drive unit includes about two air cylinder group formed of connecting, described base is also provided with two support columns, the position of described support column is corresponding with the piston rod position of air cylinder group.
When adopting technique scheme, actuating unit is formed by the cylinder of two groups of series connection, under the promotion of cylinder, drive reciprocal swing arm intermittent rotary, by shaft coupling, the rotating shaft of servo reversing valve and reciprocal swing arm are integrally connected, are driven the axis of rotation of servo reversing valve by reciprocal swing arm, and control rotating shaft and turn left and right angle, realize cut-offfing of each valve road of servo reversing valve, conveniently carry out Performance Detection and test.Because this device structure is comparatively simple, comparatively easily realize, cost is lower, has safe and reliable feature.
Further, in order to the sliding friction between reciprocal swing arm two ends and cylinder piston rod and support column is become rolling friction, the two ends of described reciprocal swing arm are hinged with two rollers.
Further, conveniently regulate the length of support column, described support column is connected with whorl of base, and support column is fixed with setting nut.
Further, in order to observe the rotational angle of reciprocal swing arm intuitively, rotating shaft place in the middle part of described reciprocal swing arm is provided with index dial.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the sectional structure schematic diagram of servo reversing valve checkout equipment embodiment of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to sectional structure schematic diagram;
The B of Fig. 3 Fig. 1 is to structural representation;
Fig. 4 is the partial enlarged drawing of Fig. 3;
The plan structure schematic diagram of Fig. 5 Fig. 1.
Embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, servo reversing valve checkout equipment of the present invention, comprise and be arranged on fixture 3 on base 1 and reciprocal swing arm 5, fixture 3 is fixed on base 1 by bearing 2.Be connected with rotating shaft 4 key in the middle part of reciprocal swing arm 5, rotating shaft 4 is connected with servo reversing valve to be measured by shaft coupling 41.Be symmetrical arranged about two air cylinder group 6 formed of connecting at the two ends of reciprocal swing arm 5, the piston rod 61 of air cylinder group 6 contacts the roller 51 of reciprocal swing arm 5 two ends setting.Base 1 has also been threaded two support columns 7, and the position of support column 7 is corresponding with the position of piston rod 61.Wherein, an index dial 52 is also had, for the rotational angle of the reciprocal swing arm of direct vision at the back side of reciprocal swing arm 5.
During use, servo reversing valve is fixed on fixture 3, its input shaft is connected with the rotating shaft 4 in reciprocal swing arm 5 by shaft coupling 41.The air cylinder group 6 of being connected by about two realizes the reciprocally swinging of reciprocal swing arm 5, thus can cut-offfing each valve road of servo reversing valve, conveniently carries out detecting and testing.Wherein because air cylinder group 6 is in series by two cylinders, when piston rod 61 ejects, it can be made to rest on three positions, i.e. two cylinders primary importance of simultaneously shrinking, a cylinder ejector, the 3rd position that the second place of a cylinder contraction and two cylinders eject simultaneously.Two air cylinder group cooperatively interact, the primary importance forming left air cylinder group is corresponding with the 3rd position of right air cylinder group, the second place of left air cylinder group is corresponding with the second place of right air cylinder group, three kinds of states that the 3rd position of left air cylinder group is corresponding with the primary importance of right air cylinder group.Corresponding with three break-make positions of servo reversing valve like this, be convenient to carry out Performance Detection.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
