Description
Technical field
The utility model relates to a kind of testing tool, particularly about a kind of diesel engine spiracle cubing.
Background technology
Diesel motor is the propulsion system of diesel locomotive, and it moves up and down in cylinder by valve, forces the valve disc of valve and valve seat carries out closely connected and open, thereby realizes the function of in engine input fuel and combustion gas.Therefore valve is as vitals, and reliability and permanance when guaranteeing diesel engine work play very important effect.
The shape and size of valve are except that the resistance minimum that guarantees gas flow, and it requires under any circumstance to guarantee the impermeability of firing chamber when closing.The condition of work of valve is very abominable simultaneously, and when diesel engine turned round, valve bore very high thermal load and impact mechanical load and exhaust gas corrosion.If therefore select the underproof valve of parameter index, will directly cause valve initial failure.So just the processing form and position tolerance parameter of valve has been proposed very strict requirement, the linearity that for example run-out tolerance of valve valve disc is not more than 0.015, valve valve rod run-out tolerance is not more than 0.02 gentle family of power and influence's bar is not more than 0.01.Above form and position tolerance parameter has an error to exceed standard, and all can influence the closely connected property of valve valve disc and valve seat, influences then gently that diesel engine fills, air capacity and work efficiency; Heavy then under long-term impact load effect, can cause valve disc to come off, thus the great quality accident that causes diesel engine to damage.In addition, because long manufacturing cost height of the process-cycle of valve as can not effectively detecting, repair and control the form and position tolerance of valve at processing site, will certainly increase manufacturing cost and incur loss through delay the product payment.Make in the production run at valve, have no idea to measure the engine valve valve line to the rod end surface size with general measurer, whether detect valve qualified all is to be undertaken by the exact instrument measurement, owing to exist instrument not easy to operate, poor accuracy, the speed of measurement is slow, and the human factor error is big, and per tour is only surveyed a valve and is let pass as initial workpiece, and efficient is low and be not easy to control in the batch production process.Chinese patent CN200920289389.0 discloses a kind of air valve inspection tool, at least comprise base and be installed on dial framework on the base, instrument and gauge head are housed on the dial framework, by screw v-shaped bearing seat and V-type locating piece are installed on the base, be equipped with the oval hole on v-shaped bearing seat and the V-type locating piece.Chinese patent CN200820123130.4 discloses a kind of diesel engine spiracle cubing, it comprises a cubing base, be disposed with two vee-blocks and a support on the axis of described cubing base, the top of described support is provided with a bolt, and the head of described bolt is provided with a decorative pearl on top of an official cap; Detected valve seating drops on described two vee-blocks, the valve rod port part of described valve, lean against on the bolt decorative pearl on top of an official cap of described support, be respectively arranged with a table bearing at the valve disc tapering point of described valve and the middle part of valve rod, two described table bearings are by being fixedly connected on the described cubing base, described cubing base is placed on the table top, is placed with one the 3rd table bearing on the described table top, the fixedly connected dial gauge of difference on described three table bearings.But complex structure, applicability are not strong.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of engine valve valve line to rod end surface size cubing, adopts the brief positioning reference of trying one's best, instrument repeatable accuracy height, and speed is fast, and it is convenient to change product type, and applicability is strong.
For achieving the above object, the utility model is taked following technical scheme: the engine valve valve line is to rod end surface size cubing, comprise base and be installed on base rail groove interior dial framework and V-block, instrument and gauge head are housed on the dial framework, described dial framework and V-block are fixed on the base by set screw, also be provided with valve valve line locating piece on the described base, described valve valve line locating piece is provided with T shape groove, and described valve valve line locating piece passes through T shape groove by set screw and base Joint.
Described instrument is the rod end surface instrument, and described gauge head is the rod end surface gauge head.
Described instrument is dial gauge or clock gauge.
Valve valve line locating piece is installed on the utility model base right side, valve valve line locating piece has T shape groove, groove right side side is provided with set screw, the radial and axial location that is used for the valve valve line, V-block is housed in the left-hand foot guide-track groove of valve valve line locating piece is used for the engine valve stem location, set screw adjusting v block is equipped with in base rail groove both sides axial location, opposite side at base is equipped with dial framework, dial gauge is installed by screw attachment on dial framework, there are two rail grooves to connect by set screw on the base with dial framework, be convenient to the adjustment of dial framework, this cubing adopts and to compare and measure direct-reading methods, can detect the valve line of the valve distance to rod end surface.
The utility model is owing to take above technical scheme, and it has the following advantages: adopt this engine valve valve line to rod end surface size cubing, and instrument repeatable accuracy height, speed is fast, and it is convenient to change product type, and applicability is strong.
