Abstract
The invention belongs to the field of a testing tool for an engine cylinder valve seat ring and in particular relates to a valve seat ring jerk testing tool. The valve seat ring jerk testing tool comprises a gauge clamping block, a rotating body and a positioning tensioning shaft, wherein the rotating body is slidingly sleeved on the positioning tensioning shaft and a conical surface at the lower end of the rotating body is provided with a threaded hole; a measuring head is mounted in the threaded hole; a conical surface at the upper end of the rotating body is in contact with a measuring contact of a dial gauge; the dial gauge is fixedly locked on the gauge clamping block through a first screw; the gauge clamping block is fixedly locked on the positioning tensioning shaft through a second screw; a limiting ring is arranged between the rotating body and the gauge clamping block; and a retainer ring is mounted on the lower part of the rotating body. The valve seat ring jerk testing tool is simple, smart and reasonable in structure, short in testing time and easy and simple to operate, and is low in measuring cost and maintenance cost and high in measurement precision.
Description
Technical field
The invention belongs to the testing tool field of cylinder cover valve washer, be specially valve retainer glitch detection instrument.
Background technology
Engine valve retainer is the vitals on engine, the installation quality of valve retainer directly affects the work quality of engine, so in production practices, usually need to detect the installation situation of valve retainer, wherein, the Fa Er face of valve retainer is an important morpheme parameter in valve retainer detection technique index relative to beating of valve guide rod hole, and this parameter directly affects the sealing of engine.
At present, the method usually detecting valve retainer has three kinds: one to be that three-dimensional detects, and the method is long for detection time, complex operation; Two is use inductance or pneumatic appliance special for detecting, and the method measurement cost is high, maintenance cost is high, is difficult to promote on a production line; Three be with backstay and dial test indicator with the use of, in the method, backstay is the maximum material boundary design of simulation valve guide rod hole, the gap that will produce when backstay and valve guide rod hole actual location, the size in gap depends on the deviate of valve guide rod hole physical size and its size under maximum solid to a great extent, make backstay center may depart from the center in valve guide rod hole like this, when causing detection, repeatable accuracy is poor, measurement data is inaccurate.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of structure simple, ingenious, rational valve retainer glitch detection instrument is provided, this testing tool measuring accuracy is high, easy to operate, cost is low, adapts to the valve retainer glitch detection mechanism of on-line checkingi.
According to technical scheme provided by the invention: valve retainer glitch detection instrument, be characterised in that: comprise table fixture block, rotary body, location tensioning shaft, described rotary body slip cap is loaded on the tensioning shaft of location, its lower end conical surface is provided with threaded hole, in threaded hole, gauge head is installed, the measurement contact of its upper end conical surface and clock gauge, described clock gauge is fixed on table fixture block by the first screw lock, and described table fixture block is fixed on the tensioning shaft of location by the second screw lock; Spacing collar is provided with between described rotary body and table fixture block; Described rotary body bottom is provided with back-up ring.
As a further improvement on the present invention, described location tensioning shaft is provided with elastic groove and the conical surface, and described elastic groove is opened in tensioning shaft lower end, location, and the described conical surface is positioned at back-up ring bottom.
As a further improvement on the present invention, tensioning shaft upper end, described location mounting handle.
As a further improvement on the present invention, described table fixture block is L shaped plate.
