Description
Technical field
The invention belongs to technical field of tooling clamps, specifically, the particularly magneto gap measuring tool of motorcycle engine.
Background technology
The coil of motorcycle engine magneto generator is fixed in the left crankcase cover, this coil is connected with sensor by wire, and sensor also is arranged in the left crankcase cover, and the magnet steel that matches with sensor is installed on the bent axle, when bent axle rotates, by the signal of sensor sensing magnet steel.Between sensor and the magnet steel suitable gap should be arranged, if the gap between sensor and the magnet steel is too small, friction even interference occur easily, on the one hand can be because interfere the generation abnormal sound; On the other hand, cause easily component wear, affect serviceable life.If the excesssive gap between sensor and the magnet steel, sensor sensing less than the signal of magnet steel, can cause engine normally not start.Therefore, in the assembling motorcycle engine, need the gap between detection magneto generator sensor and the magnet steel whether suitable.
Traditional detection mode is the center pit that passes left crankcase cover and coil with a rotating shaft, then drives the go-no go gauge rotation, judges by the spacing situation of the contact on go-no go gauge and the sensor.Because be subjected to the impact of concentricity between machining precision and left crankcase cover and the coil, rotating shaft is relatively poor in the bearing accuracy that left crankcase covers, easily produce thus erroneous judgement, the accuracy of detection is difficult to ensure.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of magneto gap measuring tool of motorcycle engine, with the gap between accurate detection magneto generator sensor and the magnet steel.
