Description
Technical field
The invention belongs to the 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: the one, on the double-screw bolt of certain altitude, coupling one nut, withstand the valve pallet, the height by adjusting nut on double-screw bolt, and then regulate valve lift; The 2nd, according to the cylinder head valve arrangement structure, process a flat board, process the tapped hole with valve knife bar consistent size and position consistency on flat board, support four contour fore-sets below dull and stereotyped, with the clamping part, flat board and cylinder cap are clamped, by tapped hole, be screwed into double-screw bolt and then reach the purpose of regulating the valve height.Front a kind of scheme, simple in structure, but require the cylinder head upper surface to have certain plane to place double-screw bolt, this is unpractical for more and more compacter air cylinder head structure, and double-screw bolt is floating being placed on the cylinder head upper surface, vibrations in test all will cause the variation of double-screw bolt, affect the lift degree of regulation; Rear a kind of scheme, a kind of cylinder diameter of every conversion, all need the annexes such as working flat plate, supporting post, and, when locating back, guarantee that flat board is on same level, otherwise lift is regulated inaccuracy, affects measuring accuracy.
Two kinds of regulating methods, when valve is installed at a certain angle, lift is all regulated inaccurate.
Summary of the invention
To the objective of the invention is in order being convenient for measuring, to reduce design and processing, and guarantee measuring accuracy, design a kind of novel valve adjustments structure.This structure is used 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 double-screw bolt 1, the first nut 2, horizontal cylinder 3, regulation locking device, guide pad 7, the second nut 8 and valve fore-set 9, laterally cylinder 3 is connected by two the first nuts 2 that are distributed in horizontal cylinder 3 one end both sides with double-screw bolt 1 top, guide pad 7 is fixedly connected with by two the second nuts 8 that are distributed in guide pad 7 one end both sides with double-screw bolt 1 bottom, laterally on cylinder 3, be provided with the regulation locking device that can move left and right and rotate and lock with horizontal cylinder 3 along horizontal cylinder 3, regulate centering for driving valve fore-set 9, valve fore-set 9 is arranged in the hole of described regulation locking device one side.
Described regulation locking device is comprised of sliding sleeve 4, circular cone copper pin 5 and nut 6, one side of sliding sleeve 4 through holes is arranged to conical bore, sliding sleeve 4 is provided with screw thread with the cylindrical of the homonymy of conical bore, circular cone copper pin 5 inside are 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 the conical bore of circular cone copper pin 5 pressure sliding sleeves 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 the one side has the gap of 1.5mm.
Described guide pad 7 is T-shaped.
Beneficial effect of the present invention: the present invention is applicable to the cylinder head of different cylinder diameters, has reduced the nonstandard design of test, has reduced expense, easy to use, quick for installation, can the proof test testing precision, can meet the different installation of valve again simultaneously.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The structural representation that Fig. 2 is regulation locking device in Fig. 1;
The structural representation that Fig. 3 is sliding sleeve;
The structural representation that Fig. 4 is circular cone copper pin.
Embodiment
As shown in Figure 1, double-screw bolt 1 is packed 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 of horizontal cylinder 3 in Y-direction; T-shaped 7, by upper and lower two the second nuts 8, itself and connecting stud 1 is fixing, by the T-shaped part of T-shaped 7, pack in the inverted T shape groove of test panel, driving whole controlling mechanism front, rear, left and right four direction moves, thereby make valve fore-set 9 movement in X side by the sliding sleeve 4 on horizontal cylinder 3, make valve fore-set 9 and valve over against, realize that lift regulates.
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, the opening circular cone copper pin 5 of packing into, the cone angle of circular cone copper pin 5 is 21.8 degree, and a side has the gap of 1.5mm, by coordinating of nut 6 and sliding sleeve 4 screw threads, opening circular cone copper pin 5 is pressed into to sliding sleeve 4, and fits tightly and be fixed on horizontal cylinder 3 with horizontal cylinder 3.
With certain angle cylinder head of packing into, carry out lift while regulating when valve, accurate in order to guarantee the lift of regulating, require valve fore-set 9 to be regulated with the valve the same angle that tilts.At this moment, sliding sleeve 4 is laterally being rotated to the angle the same with the valve inclination on cylinder 3, then, by nut 6 and sliding sleeve 4 screw-thread fit, opening circular cone copper pin 5 is being pressed on horizontal cylinder 3, achieving the goal.
