Abstract
The utility model discloses a device for measuring piston combustion chamber position tolerance. The device includes a detection bench, a magnet base plate, an axial baffle plate, a T-shaped positioning lever and a measuring mechanism. The detection bench is mounted on the magnet base plate. The axial baffle plate and the T-shaped positioning lever are both disposed on the detection bench. The measuring mechanism is disposed on a side surface of the detection bench. In this way, the device for measuring the piston combustion chamber position tolerance can help to improve work efficiency and reduce the investment of human resources. Meanwhile, a piston pass rate can be improved without destructive detection, a detection precision error can be substantially reduced, and the operation cost can be decreased.
Description
Technical field
The utility model relates to engine piston processing, particularly relates to a kind of piston combustion bowl measuring unit for position dimensions.
Background technology
Piston is motor car engine " heart ", bears mechanical load and the thermal load of alternation, is one of worst key components and parts of condition of work in engine.
And piston combustion bowl is the important working position of piston, the crudy of piston combustion bowl position degree is poor, will have influence on the transient equilibrium of engine, such as the size of firing chamber can affect ratio of compression, thereby affects the performance of engine.Each geometric parameter (aditus laryngis relative diameter, sidewall draft angles, center cone angle and transition section radius) that burns chamber has a certain impact to combustion process and engine performance tool.
At present in the inherent Piston Machining process of each factory, to the measurement of piston position degree, adopt index dial measurement mechanism to measure or Three-coordinate measurer measurement, yet adopt above-mentioned two kinds of measurement mechanisms to have destructive detection, and it is large to detect scale error, detection time is long, and work efficiency is too low.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of piston combustion bowl measuring unit for position dimensions, can increase work efficiency, reduce human cost and drop into, need not destructive detection can improve product percent of pass simultaneously, greatly limit reduces accuracy of detection error, cuts operating costs.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of piston combustion bowl measuring unit for position dimensions is provided, comprise: monitor station, magnet base plate, axial baffle, T-shaped backstay and measuring mechanism, described monitor station is arranged on magnet base plate, described axial baffle and T-shaped backstay are all arranged on monitor station top, and described measuring mechanism and axial baffle are set in parallel on monitor station.
In preferred embodiment of the utility model, described measuring mechanism comprises height gauge, dial gauge and elbow indicator, and described elbow indicator is arranged on dial gauge, and described dial gauge is arranged on height gauge.
In preferred embodiment of the utility model, the tolerance of described T-shaped backstay diameter and measurement piston pin hole is negative 0.003mm.
In preferred embodiment of the utility model, the described magnet base plate depth of parallelism is 0.001mm.
The beneficial effects of the utility model are: a kind of piston combustion bowl measuring unit for position dimensions of the utility model, can increase work efficiency, reduce human cost and drop into, need not destructive detection can improve product percent of pass simultaneously, greatly limit reduces accuracy of detection error, cuts operating costs.
