Description
Technical field
The utility model relates to the detection equipment in a kind of camshaft process, especially a kind of camshaft oilhole plug
Pressure proof performance detection device.
Background technology
The camshaft processing technology of prior art, is first to process oil hole, then press-fits plug at axle head.Due to camshaft
Have pressure oil during work in oil hole, therefore, the pressure performance press-fiting plug need to be detected.Existing characterization processes be with
The mode of oiling pressure measurement is carried out, and it operates inconvenience, time-consuming.Production is badly in need of one and can conveniently realize camshaft oilhole plug
The equipment of pressure performance detection.
Content of the invention
To be solved in the utility model haveing a problem in that provides a kind of camshaft oilhole plug pressure proof performance detection device, its knot
Structure is simple, it is simple to operation, and effect is high.
The utility model adopts the following technical scheme that and includes machine seat board, pressure testing bar, and it is fixed that described machine seat board is provided with camshaft
Position device and detection oil cylinder, the length of pressure testing bar is suitable with the length of camshaft, and detection oil cylinder is provided with the pressure being connected with PLC
Force snesor and position sensor；During test mode, camshaft is positioned on machine seat board by described camshaft positioning device, examination
Depression bar is arranged in the oil hole of camshaft, and the lower end of pressure testing bar contacts with plug upper surface, the upper end of pressure testing bar and detection
The pressure head of oil cylinder pushes against.Starting detection oil cylinder to pressurize pressure testing bar, pressure sensor and position sensor are collected data and are reached
PLC, PLC, by collected data and preset data comparison, i.e. can determine that whether the pressure performance of camshaft oilhole plug is qualified.
Its principle is: during test operation, is first positioned on machine seat board camshaft by described camshaft positioning device
(plug end of camshaft and machine seat board push against)；Then, it is arranged in pressure testing bar in the oil hole of camshaft, the lower end of pressure testing bar
Contacting with the plug upper surface being positioned at oil hole, the upper end of pressure testing bar couples pressure head；3rd step, starts detection oil cylinder 4,
Be forced into setup pressure value (determination of pressure sensor force value) under the control of PLC to pressure testing bar, plug collected by position sensor
Displacement data reaches PLC, and PLC, by collected displacement data and preset data comparison, i.e. can determine that the oilhole plug of camshaft
Whether pressure performance is qualified, and (displacement data i.e. judges that in setting range pressure performance is qualified, i.e. judges beyond setting displacement
For defective).
A kind of improvement is that described camshaft positioning device is pneumatic-finger.
Another kind of improvement is also to include a pressure testing bar positioner.Using this structure, pressure testing bar positioner can be by
The upper end stationary positioned of pressure testing bar, it is to avoid left and right bias effect tests the data precision.
Also having one to improve is that described pressure testing bar positioner is a clamping head.
The utility model has the advantage that the 1st, simple in construction, it is easy to implement.2nd, economization oiling operation, operation is more pacified
Complete convenient, alleviate the labour intensity of operator.3rd, its effect is high, improves effect more than 2 times than conventional fuel pressure measurement mode.4、
The testing result degree of accuracy is high.Oiling pressure measurement mode originally is by manually judging by the force value of observed pressure table, easily occurs by mistake
Situation about sentencing, this device relies on sensor and PLC to achieve detection automatically, it is to avoid artificial misjudgment phenomenon.
