Technical Field
The utility model relates to a be used for axiality to measure frock under narrow space, technical field such as the relevant assembly of mainly used diesel engine transmission shaft, regulation.
Background
At present, a camshaft of a high-pressure oil pump of a marine diesel engine and a driving gear of a gear box are usually connected by a coupling, and power transmission consists of a gear box oil pump driving shaft, a spring piece, an intermediate shaft, the spring piece and an oil pump camshaft.
When the high-pressure oil pump is assembled, the alignment of the coaxiality of the camshaft of the high-pressure oil pump and the driving shaft at the gear end is particularly critical, and the phenomena of overlarge jump of the intermediate shaft, unstable torque transmission, tearing of the spring piece and the like are easily caused by out-of-tolerance. Because the high-pressure oil pump passes through the support assembly on the organism, oil pump camshaft center is too close to the organism, and ordinary percentage table can't accomplish the rotation measurement of a week. Usually, the dial indicator can only be used for measuring the upper side, the lower side and the front side, the coaxiality can not be detected when the dial indicator is close to a machine body, only the machining precision can be relied on, and the deviation is large.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the utility model provides a coaxiality measures frock under being used for narrow space, guarantees the installation accuracy of diesel engine high pressure oil pump, improves power transmission's reliability, avoids the spring leaf to tear.
A frock for axiality measures under narrow space, including measuring the frame, measure frame one end and be the location end of vertical setting, the other end is the measurement end that the level set up, and the location end is equipped with waist type hole, the downthehole fastener that is equipped with of waist type, the measurement end sets up adjusting part, adjusting part and measurement end threaded connection.
The measuring rack is characterized in that the measuring rack is a connecting rod horizontally arranged, the positioning end is arranged on a plane plate perpendicular to the connecting rod, a waist-shaped hole is formed in the plane plate, the fastener comprises a bolt and a nut, the bolt penetrates through the waist-shaped hole, and the nut is installed at the end of the bolt.
The waist-shaped hole is vertically arranged on the plane plate.
The adjusting component comprises an adjusting flat end screw and a clearance gauge, a measuring end of the connecting rod is provided with a threaded hole corresponding to the adjusting flat end screw, and the adjusting flat end screw penetrates through the threaded hole.
The measuring stand is of an L-shaped integrally formed plate type structure.
The bolt is a hexagon head bolt.
The positioning end of the measuring tool is adjusted to a proper position through a kidney-shaped hole and then fixed on a bolt hole of a flange at the driving end of the oil pump through a bolt and a nut, a threaded hole at the other end of the measuring tool is screwed into an adjusting flat end screw and then rotates the flange at the driving end of the oil pump for a circle, the adjusting flat end screw enables the flat end of the adjusting tool to be in a proper distance from the excircle of the flange at the gear end, and the distance is not too large and is preferably a small amount of clearance gauges can be plugged in. After the adjustment is finished, the flange at the pump end is rotated to enable the flat end adjusting screws to be respectively positioned to the first position, the second position, the third position and the fourth position, and meanwhile, a proper clearance gauge is selected to measure the clearance. And the upper, lower, inner and outer positions of the oil pump bracket are adjusted according to results, so that the gap in four directions meets the requirements.
The utility model has the advantages that:
the utility model discloses an use and to realize all-round axiality and measure to the axiality has been guaranteed in the accurate adjustment, has avoided because of the various unfavorable consequences that the overproof caused. The structure is simple and reasonable, the installation accuracy of the high-pressure oil pump of the diesel engine is ensured, the reliability of power transmission is improved, and the spring piece is prevented from being torn.
