Detailed description of the invention
A kind of engine air door fitting unit, comprises drag lever 1, supports threaded rod 2, valve platen seat 3, platen pillar 4, annular platen 5, it is characterized in that: drag lever 1 is flexibly connected with support threaded rod 2, valve platen seat 3 respectively; Support threaded rod 2 tailing screw flight specifications identical with the collet threaded hole of cylinder cap top plane distribution top board; There is valve collet installing hole at annular platen 5 centers, and on valve platen seat 3 below disks and annular platen 5, correspondence respectively has two positioning through hole; Platen pillar 4 two ends are inserted respectively the positioning through hole on valve platen seat 3 and annular platen 5 and are fixedly connected by welding.
In anti-air-stop gate installation process, because hand cunning causes operate miss, preferably carry out " annular knurl " anti-skidding processing at the shaft afterbody of drag lever 1.
Preferably drag lever 1 with the connected mode that supports threaded rod 2 is: drag lever 1 shaft head is milled with two head parallel surfaces, and hinged connection hole on head parallel surface is supported threaded rod 2 heads and is milled with location U-lag, hinged connection hole on groove both wings; The head parallel surface thickness of drag lever 1 is equal to or slightly less than and supports threaded rod 2 and locate the width of U-lag; The hinged through hole that drag lever 1 and support threaded rod 2 pass on hinged through hole and the support threaded rod 2 head location U-lag both wings on drag lever 1 head parallel surface by bolt is flexibly connected.
Preferably drag lever 1 with the connected mode of valve platen seat 3 is: drag lever 1 shaft middle part is milled with two middle part parallel surfaces, has slideway elongated slot on the parallel surface of middle part; Valve platen seat 3 tops are milled with the location U-lag that slides, the hinged connection of groove both wings hole, and the thickness of the middle part parallel surface of drag lever 1 is equal to or slightly less than the width of the slip location U-lag of valve platen seat 3; Drag lever 1 and valve platen seat 3 pass the slideway elongated slot on slip location U-lag and the drag lever 1 shaft middle part parallel surface of valve platen seat 3 tops hinged through hole by bolt is flexibly connected.
Drag lever 1 is simple and reliable with the connected mode that the bolt that supports threaded rod 2 and valve platen seat 3 is movably hinged, and cost is low, and the process-cycle is short, is a kind of connected mode of relatively optimizing.
For there are platen seat 3 sliding phenomenons in anti-air-stop gate erecting device in the time that valve is installed, also comprise anti-skidding locking plate 6, there is fastening bolt through hole at described anti-skidding locking plate 6 centers, and drag lever 1 is connected with the fastening bolt through hole on anti-skidding locking plate 6 with the slideway elongated slot that anti-skidding locking plate 6 passes on drag lever 1 shaft middle part parallel surface by bolt.
The concrete assembling of 2 pairs of valve erecting devices and valve installation process are described by reference to the accompanying drawings:
1) two platen pillars 4 are inserted into respectively in the locating hole on valve platen seat 3 and annular platen 5, under the prerequisite that ensures the two disk depth of parallelisms, three are welded, and the welding slag after welding is cleared up;
2) utilize U-shaped slide groove and drag lever 1 on valve retainer seat 3 to assemble valve platen seat 3, platen pillar 4, annular platen 5 parts after welding, and adopt screw bolt and nut standard component to connect, without fastening;
3) two anti-skidding locking plates 6 are installed on two parallel planes of drag lever 1 slide groove, are located at valve platen seat 3 and support between threaded rod 2, and adopting screw bolt and nut standard component to connect, without fastening;
4) be screwed in the distribution top board collet threaded hole in the plane of cylinder cap top supporting threaded rod 2, again the drag lever 1 that valve platen seat 3 parts, anti-skidding locking plate 6 parts are installed is arranged in the U-shaped chute that supports threaded rod 2, and adopt screw bolt and nut standard component to connect, carry out fastening;
5) make to slide in the slideway of valve platen seat 3 parts on drag lever 1, determine that valve platen 3 parts and valve to be installed are on a upright position, screw bolt and nut standard component on fastening valve platen seat 6, the screw bolt and nut standard component on fastening anti-slip locking plate 6;
6) adjusting support threaded rod 2 is screwed into into the degree of depth of cylinder cap top plane distribution top board screwed hole, making to support threaded rod 2 becomes the fulcrum of having an effect of valve erecting device, needs to ensure that valve platen seat 3 parts contact with valve to be installed and have certain compression travel simultaneously;
7) after above-mentioned preparation completes, operating personnel A holds the axle journal section that drag lever 1 afterbody processed through " annular knurl " and presses down drag lever 1, now valve spring and spring holder can produce a descending stroke thereupon, along with the annular slot that moves down valve head of spring holder is exposed to spring holder outside, coordinate subsequently personnel B two valve collets to be installed in the annular slot of valve head, locker blocks rear operating personnel A and lifts drag lever 1, spring holder after rising can utilize valve collet that valve is pinned under the active force of valve spring, after removing valve erecting device, complete the installation process to a valve gear,
8) for the installation of different head valve devices, only need to change the screw thread specification that supports threaded rod 2 afterbodys, utilize the position of slideway adjustment valve platen seat 3 parts on drag lever 1, without again processing valve erecting device simultaneously.
