The invention relates to the automobile component measurement technology field, relates to pipe fitting products applied to pressed-in castings of high precision measurement automobile engine systemsand particularly relates to an auxiliary device for automobile pipe fitting high precision measurement. The auxiliary device comprises three supporting pins, a base seat, ventilation pipes, a precisesleeve and a positioning adjusting block, wherein the center of the base seat is provided with a step through hole, periphery of the base seat is provided with four base seat through holes, peripheryof the precise sleeve is provided with four sleeve through holes, one ventilation pipe can be inserted into one base seat through hole and the corresponding sleeve through hole in a clearance fit mode, and the ventilation pipes stretch into one end of the precise sleeve and are overlapped with an inner wall arc of the precise sleeve. The auxiliary device is advantaged in that on the condition thatmeasurement operation is not influenced, work smoothness in the measurement process can be better guaranteed, operation is convenient, service life can be improved, measurement precision and accuracyare guaranteed, the structure is simple, operation is quite convenient, and strong universality and high measurement accuracy are realized.
Description
Technical field: [0001] The invention relates to the technical field of auto parts measurement, in particular to high-precision measurement of pipe fitting products pressed into castings in automobile engine systems, and in particular to an auxiliary device for high-precision measurement of automobile pipe fittings. Background technique: [0002] In the automobile engine system, in order to realize functions such as ventilation, oil passage, drainage, and exhaust, the corresponding press-in port holes will be processed in the castings, mainly to match the press-in end parts of the pipe fittings, because the engine system cannot leak Therefore, the dimensional accuracy of the inner hole of the casting is extremely high, and the dimensional accuracy of the outer diameter of the corresponding pipe fitting is also extremely high. In order to ensure the diameter of the press-fit end of the pipe fittings, the traditional method often uses an outer micrometer for full inspection. T...
