Description
Technical field
The utility model is related to valve detection field.
Background technology
Engine is as the core of motor vehicle, and the various parameters influence of the difference of its performance on vehicle is very big.Especially
It is that in the air distribution system of engine, the linearity of engine inlet and outlet door and conical surface bounce are two critically important indexs,
Can its mechanical efficiency and fuel oil to whole engine fully burn with especially important influence.
Engine valve must assure that valve processing reaches certain precision in process of production so that valve is when in use
The problems such as being not in gas leakage, traditional valve detection means includes table base, V-type fixture, handle, dial gauge, contrast
Instrument and drive mechanism, detection method is：Hand-turning valve, the linearity of valve is detected with comparison instrument, then uses centimeter check
Its conical surface is beated, and operation in two steps is completed, and artificial reading simultaneously records testing result.
Detect there is following defect in this way：1st, the detection of single-piece valve need to spend 5 minutes, and efficiency is low, and
It can only inspect by random samples, it is difficult to control the quality of product comprehensively, it is impossible to the need for adapting to extensive assembling；2nd, the essence of dial gauge, comparison instrument
Degree it is not high, it is impossible to meet engine assembly it is high-precision to valve size requirement, and need staff observe at any time dial gauge,
Data variation on comparison instrument, it is determined that the qualification of detection valve, is inconvenient；3rd, due to artificial rotary valve, different people
Rotating speed can be different, it is difficult to ensure the uniformity of testing conditions.
The content of the invention
The utility model be intended to provide the valve of the linearity that can quickly, accurately detect valve and conical surface beating degree a kind of from
Motion detection device.A kind of valve automatic test device in this programme, including table base, and it is vertical with table base
Vertical mounting bracket, it is characterised in that be sequentially provided with feeding mechanism on the table base from left to right, drive mechanism and go out
Expect from top to bottom to be disposed with transmission mechanism and testing agency on mechanism, the vertical mounting bracket；
