Abstract
The utility model discloses a concentricity detection device for an oil sealing hole and camshaft holes in the cylinder cover of an engine, which comprises a core rod. The core rod comprises a detection shaft with the size thereof matched with both the apertures of the camshaft holes and the aperture of the oil sealing hole, a handle and a positioning block arranged between the detection shaft and the handle. The side surface of the positioning block, positioned towards the detection shaft, is served as a positioning surface for the positioning of the oil sealing hole relative to a thrust surface. Compared with the prior art, the core rod with the size thereof matched with both the aperture of each of all the camshaft holes and the aperture of the oil sealing hole is prepared, wherein the core rod is provided with a positioning surface for the positioning purpose. During the concentricity detection of the oil sealing hole and the camshaft holes in the cylinder cover, the core rod is penetrated through each of all camshaft holes and the oil sealing hole from one end of the oil sealing hole and then is freely rotated by a full turn to complete the detection. Meanwhile, operators can immediately operate the device without being trained. Therefore, the device is convenient in operation and high in detection efficiency.
Description
Technical field
The utility model relates to the engine cubing, and specifically, the utility model relates to a kind of engine cylinder-cap oil seal hole and camshaft hole axiality detection device.
Background technology
Cam mechanism is widely used in automated machine, exact instrument, the automation control system, as piston-engined critical component, camshaft is to influence the critical piece that engine valve opens and closes gap length and distribution efficient, and camshaft also drives ignition distributor, lubricating oil pump, petrol pump work simultaneously.At this wherein, camshaft hole is the main position of supporting cam wheel axle, its precision situation will directly affect the key property of camshaft work, particularly the right alignment of engine cylinder-cap oil seal hole and camshaft hole is to its Effect on Performance, can cause the spacious or poor sealing of valve pine, to such an extent as to this performance also is listed in the important indicator of engine performance quality sometimes.
Coaxiality error is the decentraction that is reflected in the center of circle on the xsect.Along with improving constantly of engine cylinder-cap oil seal hole and camshaft hole robotization level of processing, for high precision, detect this position right alignment of engine expeditiously, and correctly handle, evaluate its every fabrication error, in time feed back the quality information of cylinder-cap oil seal hole and camshaft hole rapidly, traditional optical-mechanical amount instrument and the method that adopts artificial data to handle can not adapt to the actual detected needs that cylinder-cap oil seal hole and camshaft hole processing quality are managed.
In addition, in engine cylinder-cap oil seal hole and camshaft hole actual measurement, the measurement of right alignment is subjected to many-sided influence, and operator's self diathesis is with different to the understanding of drawing technological requirement; The detecting error of measuring machine, the error of probe itself; The machining state of workpiece, surfaceness; The selection of detection method, the combination of the laying of workpiece, probe; External environment conditions etc., the temperature between for example detecting, humidity etc. all can be brought certain error to measurement, and determination efficiency is low.
The utility model content
Technical problem to be solved in the utility model is a kind of engine cylinder-cap oil seal hole and camshaft hole axiality detection device, to reach the purpose that improves detection efficiency.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of engine cylinder-cap oil seal hole and camshaft hole axiality detection device, it is a plug, the detection axle that plug comprises and described camshaft hole aperture and oil sealing hole aperture are complementary, handle and at the locating piece that detects between axle and the handle be the locating surface of locating at the thrust surface place of oil sealing hole towards the side of detecting axle on the locating piece.
The described end of detecting axle is the seeker of taper.
Be provided with annular knurl at described handle.
Be provided with hanging hole at described handle.
The utility model adopts technique scheme, compared with prior art, make a plug that is complementary with each camshaft hole aperture and oil sealing hole aperture, have the locating surface location on this plug, only need when detecting the cylinder head oil sealing hole with the camshaft hole right alignment this plug from oil sealing hole one end by each camshaft hole and oil sealing hole and rotate one and enclose and get final product freely, and the employee need not training especially can operation on duty, easy to operate, the detection efficiency height.
