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 forms and two above hydraulic fluid ports.Communication, cut-out and the commutation that realizes hydraulic oil stream, and the valve of discharge degree and sequentially-operating control.Can be divided into hand-operated direction valve, solenoid directional control valve, electro-hydraulic reversing valve etc.By the outer drive transmission device rotating driveshaft of valve, band shakes connecting lever during work, starts valve plate, when making working fluid and lead to the lower part outlet of valve from left entry, the time and lead to lower part outlet from the right entry conversion, realized the purpose that periodic transformation flows to.This change over valve has a wide range of applications in oil, Chemical Manufacture, and is the most commonly used in the ammonia system.In addition, reversal valve also can make the structure of clack type, and is multiplex in the occasion than low discharge.Only need rotate handwheel comes the conversion working fluid by flap the flow direction during work.
Servo reversing valve is usually used in the hydrostatic control part of automobile, after accepting the electric simulation signal, and corresponding output control valve door.In electrohydraulic servo system, it couples together electric part and hydraulic part, is the core of electrohydraulic servo system.Because its design feature is difficult to find ready-made checkout equipment when detecting and test, and needs 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 carry out clamping and fixing to servo reversing valve, and test or detect.
For achieving the above object, technical scheme of the present invention is: the servo reversing valve checkout equipment, comprise the clamping device and the reciprocating mechanism that are arranged on the base, described clamping device comprises the bearing that is fixed on the base, described bearing is provided with the anchor clamps of clamping servo reversing valve, described reciprocating mechanism comprises a rotating shaft that is connected with servo reversing valve, be fixedly installed a reciprocal swing arm in the rotating shaft, the two ends of described reciprocal swing arm have been symmetrical arranged two reciprocating drive units, described reciprocating drive unit has comprised two up and down air cylinder group of series connection formation, also be provided with two support columns on the described base, the position of described support column is corresponding with the piston rod position of air cylinder group.
When adopting technique scheme, cylinder by two groups of series connection forms actuating unit, under the promotion of cylinder, drive reciprocal swing arm intermittent rotary, be integrally connected with reciprocal swing arm by the rotating shaft of shaft coupling with servo reversing valve, the rotating shaft that drives servo reversing valve by reciprocal swing arm is rotated, and the control rotating shaft turns 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, realize that comparatively easily cost is lower, has safe and reliable characteristics.
Further, for the sliding friction between reciprocal swing arm two ends and cylinder piston rod and the support column is become rolling friction, the two ends of described reciprocal swing arm are hinged with two rollers.
Further, for convenient length of regulating support column, described support column is connected with whorl of base, is fixed with setting nut on the support column.
Further, in order to observe intuitively the rotational angle of reciprocal swing arm, rotating shaft place at described reciprocal swing arm middle part is provided with index dial.

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the sectional structure synoptic diagram of servo reversing valve checkout equipment embodiment of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to the sectional structure synoptic 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 synoptic diagram of Fig. 5 Fig. 1.
Embodiment
Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, servo reversing valve checkout equipment of the present invention comprises the anchor clamps 3 and the back and forth swing arm 5 that are arranged on the base 1, and anchor clamps 3 are fixed on the base 1 by bearing 2.Back and forth swing arm 5 middle parts are connected with rotating shaft 4 keys, and rotating shaft 4 is connected with servo reversing valve to be measured by shaft coupling 41.Be symmetrical arranged two up and down air cylinder group 6 of series connection formation at the two ends of back and forth swing arm 5, the piston rod 61 of air cylinder group 6 contacts the roller 51 that reciprocal swing arm 5 two ends arrange.Two support columns 7 that also have been threaded on the base 1, the position of support column 7 is corresponding with the position of piston rod 61.Wherein, also have an index dial 52 at the back side of back and forth swing arm 5, be used for the rotational angle of observing reciprocal swing arm directly perceived.
During use, servo reversing valve is fixed on the anchor clamps 3, its input shaft is connected with rotating shaft 4 in the reciprocal swing arm 5 by shaft coupling 41.By two up and down the air cylinder group 6 of series connection realize the reciprocally swinging of reciprocal swing arm 5, thereby can to the cut-offfing of each valve road of servo reversing valve, conveniently detect and test.Wherein because air cylinder group 6 is to be in series by two cylinders, when piston rod 61 ejects, can make it rest on three positions, i.e. two primary importances that cylinder shrinks simultaneously, a cylinder ejector, the second place and two the 3rd positions that cylinder ejects simultaneously that cylinder shrinks.Two air cylinder group cooperatively interact, the primary importance that forms 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 only is preferred implementation of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
