Abstract
The utility model discloses servo reversing valve detecting equipment. The servo reversing valve detecting equipment comprises a clamping mechanism and a reciprocating mechanism which are arranged on a base. The clamping mechanism comprises a support seat fixed on the base. A fixture used for clamping a servo reversing valve is arranged on the support seat. The reciprocating mechanism comprises a rotating shaft connected with the servo reversing valve. A reciprocating swing arm is fixedly arranged on the rotating shaft. Two reciprocating drive devices are symmetrically arranged at two ends of the reciprocating swing arm. The reciprocating drive devices comprise two air cylinder groups formed in a top-bottom series connection mode. Two support columns are further arranged on the base. The positions of the support columns correspond to those of piston rods of the air cylinder groups. Through power mechanisms formed by two groups of air cylinders which are connected in series, under pushing of the air cylinders, the reciprocating swing arm is driven to do intermittence rotation. The rotating shaft of the servo reversing valve and the reciprocating swing arm are connected into a whole through a couple, and the reciprocating swing arm drives the rotating shaft of the servo reversing valve to rotate, so the servo reversing valve detecting equipment achieves switch-on and switch-off of valve paths of the servo reversing valve, and facilitates performance detection and test.
Description
Technical field
The utility model relates to a kind of detection facility, is specifically related to a kind of test experience equipment of servo selector valve.
Background technique
Selector valve is the position control valve with two or more liquid forms and two above hydraulic fluid ports.Be 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, drive and shake connecting lever during work, start valve plate, when making working fluid and lead to the lower exit of valve from left entry, the time and lead to lower exit from the right entry conversion, realized the purpose that periodic transformation flows to.This transfer valve has a wide range of applications in oil, Chemical Manufacture, and is the most commonly used in the ammonia system.In addition, selector valve also can make the structure of flap formula, the occasions that are used for than small flow more.Only need rotate handwheel comes the conversion working fluid by flap the flow direction during work.
Servo selector valve is usually used in the hydraulic control part of automobile, after accepting the electric simulation signal, and corresponding output control valve.In electrohydraulic servo system, it couples together electric part and hydraulic part, is the core of electrohydraulic servo system.Because its structural feature is difficult to find ready-made detection facility when detecting and test, and needs autonomous Design and innovation.
The model utility content
The purpose of this utility model is to provide a kind of servo selector valve detection facility, can carry out clamping and fixing to servo selector valve, and experimentizes or detect.
For achieving the above object, the technical solution of the utility model is: servo selector valve detection facility, 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 the servo selector valve of clamping, described reciprocating mechanism comprises a rotating shaft that is connected with servo selector valve, 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 cylinder block of series connection formation up and down, also be provided with two supporting posts on the described base, the position of described supporting post is corresponding with the piston rod position of cylinder block.
When adopting technique scheme, cylinder by two groups of series connection forms power mechanism, under the promotion of cylinder, driving reciprocal swing arm intermittently rotates, by coupling the rotating shaft of servo selector valve is connected one with reciprocal swing arm, the rotating shaft that drives servo selector valve by reciprocal swing arm is rotated, and controls rotating shaft and turn left and right angle, realize cut-offfing of each valve road of servo selector 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 supporting post is become rolling friction, the two ends of described reciprocal swing arm are hinged with two rollers.
Further, regulate the length of supporting post for convenience, described supporting post is connected with whorl of base, is fixed with adjusting nut on the supporting post.
Further, in order to observe the rotation angle of reciprocal swing arm intuitively, rotating shaft place at described reciprocal swing arm middle part is provided with dial.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the servo selector valve detection facility of the utility model embodiment's sectional structure schematic representation;
Fig. 2 is that the A-A of Fig. 1 is to the sectional structure schematic representation;
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 representation of Fig. 5 Fig. 1.
Embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the servo selector valve detection facility of the utility model 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 selector valve to be measured by coupling 41.Be symmetrical arranged two cylinder block 6 of series connection formation up and down at the two ends of back and forth swing arm 5, the piston rod 61 of cylinder block 6 contacts the roller 51 that reciprocal swing arm 5 two ends arrange.Two supporting posts 7 that also have been threaded on the base 1, the position of supporting post 7 is corresponding with the position of piston rod 61.Wherein, also have a dial 52 at the back side of back and forth swing arm 5, be used for the rotation angle of observing reciprocal swing arm directly perceived.
During use, servo selector valve is fixed on the anchor clamps 3, its input shaft is connected with rotating shaft 4 in the reciprocal swing arm 5 by coupling 41.By two up and down the cylinder block 6 of series connection realize the reciprocally swinging of reciprocal swing arm 5, thereby can the cut-offfing of each valve road of servo selector valve conveniently be detected and test.Wherein because cylinder block 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 ejects, the second place and two the 3rd positions that cylinder ejects simultaneously that cylinder shrinks.Two cylinder block cooperatively interact, the primary importance that forms left cylinder block is corresponding with the 3rd position of right cylinder block, the second place of left side cylinder block is corresponding with the second place of right cylinder block, three kinds of states that the 3rd position of left cylinder block is corresponding with the primary importance of right cylinder block.Corresponding with three break-make positions of servo selector valve like this, be convenient to carry out Performance Detection.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
