Abstract
The utility model relates to an engine air intake side vibration detection device which comprises a vibration detection device body, a vibration sensor arranged in the vibration detection device body, and a detection-use ejector pin connected with the vibration sensor. The vibration detection device is characterized in that the vibration detection device props up the vibration sensor (5) through a spring (7) and a pressing ring (6) and presses the ejector pin (1) through a gland (2). The vibration detection device can satisfy the on-line detection requirement, can detect the measurement of the vacuum degree at the entrance of an intake manifold and the vibration on the engine air intake side rapidly and accurately, and has the advantages of simple structure, and convenient mounting and maintenance.
Description
Technical field
The utility model relates to a kind of Engine Block Test field, and particularly, the utility model relates to a kind of pick-up unit that is used for motor car engine air inlet side shock conditions.
Background technology
For motor car engine, no matter be spark ignition type gasoline engine or compression diesel engine, all need to finish before use corresponding test, to guarantee the correlated performance requirement of product.Comprising the vacuum tightness of test inlet manifold porch, the detection of engine charge side shock conditions, to calculate Max/Min and valve opening/off-position, valve leak amount etc.The purpose of this test mainly is to compress consistance by the related data of intake vacuum to determine air inlet system (gas admittance valve/guide rod/air intake opening/O-ring seal/tappet etc.), detects air inlet timing, valve closing open position.The fault that can detect comprises: gas admittance valve/seat leakage, camshaft phase mistake, hydraulic tappet the is too soft defective relevant with the valve phase place; Finally determine by a series of test datas that comprise the intake vacuum test whether tested engine exists assembling and parts defective.
The test of related data is to carry out under the state of engine thermal examination in the prior art, promptly needs to add fuel oil, and engine needs ignition, and toxic emission is arranged in test process, has caused corresponding energy dissipation and environmental pollution; Sometimes even need carry out destructive testing; Its test process is loaded down with trivial details and uneconomical.Its most important defective is to finish dependence test on production line, thereby is unfavorable for large-scale production, is unfavorable for the raising of production efficiency.In addition, in order to satisfy the requirement of online detection, need measuring mechanism can realize fast, vacuum tightness, the vibrations of engine charge side to test inlet manifold porch accurately detect.
The utility model content
For achieving the above object, technical problem to be solved in the utility model is to provide a kind of mechanism of under cold examination state engine charge side shock conditions being detected, and it can realize that related data reads in the fast detecting of production scene.
The technical solution of the utility model is as follows:
A kind of engine charge side shock detection device, described engine charge side shock detection device comprises the shock detection device body, be arranged at shock sensor and connected detection push rod in the described shock detection device body, it is characterized in that, described shock detection device withstands shock sensor 5 by spring 7 and trim ring 6, pushes down push rod 1 by gland 2.
Thus, by the centering effect of dual threaded screw 4, make push rod 1 when workpiece enters detected state again, the vibrations of workpiece air inlet side can accurately be delivered on the shock sensor 5.
According to engine charge side shock detection device of the present utility model, it is characterized in that described shock detection device is made center fixation by dual threaded screw 4 between shock detection device body 3 and shock sensor 5.
The center fixation effect of doing by dual threaded screw 4 makes push rod 1 when workpiece enters detected state, and the vibrations of workpiece air inlet side can accurately be delivered on the shock sensor 5.
According to engine charge side shock detection device of the present utility model, it is characterized in that the distance between push rod and the tested engine can be regulated by setting nut.
According to engine charge side shock detection device of the present utility model, it is characterized in that described shock detection device body (3) is formed with through hole in the information transmission cabling usefulness.
According to engine charge side shock detection device of the present utility model, can satisfy online detection requirements, can realize that fast vacuum tightness, the vibrations of engine charge side to test inlet manifold porch accurately detect.And simple in structure, be convenient to installation and maintenance.

Embodiment
Below, with reference to accompanying drawing, specify engine charge side shock detection device of the present utility model with embodiment.
Embodiment 1
A kind of engine charge side shock detection device, described engine charge side shock detection device comprises the shock detection device body, is arranged at shock sensor and connected detection push rod in the described shock detection device body.Described shock detection device withstands shock sensor 5 by spring 7 and trim ring 6, pushes down push rod 1 by gland 2.
Thus, by the centering effect of dual threaded screw 4, make push rod 1 when workpiece enters detected state again, the vibrations of workpiece air inlet side can accurately be delivered on the shock sensor 5.
At described shock detection device between shock detection device body 3 and shock sensor 5, by the center fixation of doing of dual threaded screw 4.Do the center fixation effect by dual threaded screw 4, make push rod 1 when workpiece enters detected state, the vibrations of workpiece air inlet side can accurately be delivered on the shock sensor 5.
In the present embodiment, the distance between described two setting nut scalable push rods and the tested engine.In addition, cabling when through hole made things convenient for information transmission during described shock detection device body 3 was formed with has screw centering between push rod and the shock sensor.
According to engine charge side shock detection device of the present utility model, can satisfy the requirement of online detection, measuring mechanism can realize that fast vacuum tightness, the vibrations of engine charge side to test inlet manifold porch accurately detect.Can realize fast detecting, the accuracy height; And simple in structure, be convenient to installation and maintenance.
