Description
Technical field
The invention belongs to air flue test field, be specifically related to a kind of valve lift controlling device.
Background technique
Common air flue test stand valve lift adjustment mechanism: one is mate a nut on the stud of certain altitude, withstands valve pallet, by the height of adjusting nut on stud, and then regulates valve lift; Two is according to cylinder head valve arrangement structure, processing one is dull and stereotyped, flat board processes with valve knife bar consistent size and the tapped hole of position consistency, the fore-set that support four is contour below flat board, with clamping part, flat board and cylinder cap are clamped, be screwed into stud by tapped hole and then reach the object regulating valve heights.Front a kind of scheme, structure is simple, but require that cylinder head upper surface has certain plane to place stud, this is unpractical for more and more compacter air cylinder head structure, and stud floats to be placed on cylinder head upper surface, vibrations in test all will cause the change of stud, affect lift degree of regulation; Rear a kind of scheme, often converts a kind of cylinder diameter, all needs the annex such as working flat plate, supporting post, and when locating back, ensure dull and stereotyped in same level, otherwise lift regulates inaccuracy, affects measuring accuracy.
Two kinds of regulating methods, when valve is installed at a certain angle, lift all regulates inaccurate.
Summary of the invention
The object of the invention is conveniently to measure, reduce design and processing, and ensure measuring accuracy, design a kind of novel valve adjustments structure.This structure uses simple, and precision is high, economical reliable, by the design of an opening circular cone copper pin, realizes the fine adjustment of valve lift.
The technical solution used in the present invention: a kind of valve lift controlling device, it comprises stud 1, first nut 2, horizontal cylinder 3, regulation locking device, guide pad 7, second nut 8 and valve fore-set 9, horizontal cylinder 3 is connected by the first nut 2 that two are distributed in both sides, horizontal cylinder 3 one end with stud 1 top, guide pad 7 is fixedly connected with by the second nut 8 that two are distributed in both sides, guide pad 7 one end with stud 1 bottom, horizontal cylinder 3 is provided with and can transversely moves left and right and rotate and the regulation locking device of locking with horizontal cylinder 3 by cylinder 3, centering is regulated for driving valve fore-set 9, valve fore-set 9 is arranged in the hole of described regulation locking device side.
Described regulation locking device is made up of sliding sleeve 4, circular cone copper pin 5 and nut 6, conical bore is arranged in the side of sliding sleeve 4 through hole, sliding sleeve 4 is provided with screw thread with the cylindrical of the homonymy of conical bore, circular cone copper pin 5 inside is through hole, outer peripheral surface is conical surface, sliding sleeve 4 is sleeved on horizontal cylinder 3, the circumferential surface of circular cone copper pin 5 and the conical bore of sliding sleeve 4 are connected, nut 6 is threaded with sliding sleeve 4, for in the conical bore of circular cone copper pin 5 pressure sliding sleeve 4, reach the effect be locked.
The cone angle of the conical bore of described sliding sleeve 4 is 21.8 degree.
The cone angle of described circular cone copper pin 5 is 21.8 degree, and its side has the gap of 1.5mm.
Described guide pad 7 is T-shaped piece.
Beneficial effect of the present invention: the present invention is applicable to the cylinder head of different cylinder diameter, decreases test non-standard de-sign, reduces expense, easy to use, quick for installation, can proof test testing precision, can meet again the different installation of valve simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of regulation locking device in Fig. 1;
Fig. 3 is the structural representation of sliding sleeve;
Fig. 4 is the structural representation of circular cone copper pin.
Embodiment
As shown in Figure 1, stud 1 loads in the hole of horizontal cylinder 3, by upper and lower two the first nuts 2, according to the height of cylinder head, controls the displacement in the Y direction of horizontal cylinder 3; T-shaped piece 7, by upper and lower two the second nuts 8, itself and connecting stud 1 are fixed, load in the inverted T shape groove of test panel by the T-shaped part of T-shaped piece 7, whole controlling mechanism front, rear, left and right four direction is driven to move, thus make valve fore-set 9 by the movement of sliding sleeve 4 in X side on horizontal cylinder 3, make valve fore-set 9 and valve just right, realize lift and regulate.
Sliding sleeve 4 is contained on horizontal cylinder 3, front portion is designed to the circular cone of 21.8 degree, in circular cone in sliding sleeve 4, load an opening circular cone copper pin 5, the cone angle of circular cone copper pin 5 is 21.8 degree, and side has the gap of 1.5mm, by coordinating of nut 6 and sliding sleeve 4 screw thread, opening circular cone copper pin 5 is pressed into sliding sleeve 4, and fits tightly with horizontal cylinder 3 and be fixed on horizontal cylinder 3.
When valve loads cylinder head with certain angle, when carrying out lift adjustment, accurate in order to ensure the lift regulated, require that valve fore-set 9 regulates with the angle that valve inclination is the same.At this moment, sliding sleeve 4 is rotated on horizontal cylinder 3 the same angle that to tilt with valve, then by nut 6 and sliding sleeve 4 screw-thread fit, opening circular cone copper pin 5 is pressed on horizontal cylinder 3, achieves the goal.
