Description
Technical Field
The utility model relates to a detection device especially relates to a crankshaft oil drill way chamfer high point detection device.
Background
The crankshaft main shaft and the connecting rod oil hole are arranged in the engine, and lubricating oil is filled between the bearing bushes through pressure to form an oil film. The fit clearance of the bearing bush is about 0.012, and the formation of an oil film effectively ensures the movement of the bearing bush. The oil hole opening is needed to be chamfered when the crankshaft oil hole is drilled in production, and the plastic deformation generated in chamfering can cause high points on the surface of a shaft neck due to the processing of a bench drill and a chamfering drill in the chamfering process. High points on the journal surface may also be present if the polishing process is not proper.
The current detection mode is to use ADCOLE or roundness measuring equipment to measure, but also need shield the data of oil orifice position when measuring to the orifice position, otherwise can influence final form and position tolerance data, in addition, use above detection equipment to detect also to waste time and energy, if not handling to the high point of oil orifice department, can cause the abnormal contact of axle bush in the engine of packing into, wear to the high point of complex tile, finally form the axle journal and draw the tile phenomenon.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: to the problem, the utility model aims at providing a bent axle oil drill way chamfer high point detection device makes the detection of oil drill way high point more simple and convenient, swift, accurate.
The technical scheme is as follows: the utility model provides a bent axle oil drill way chamfer high point detection device, includes first, the fastener of lever amesdial, fixing base, half tile, fastener two, the lever amesdial pass through fastener one with the fixing base is connected, half tile pass through fastener two with the fixing base is connected, half tile's lateral surface with the fixing base laminating, the medial surface is laminated with the outer lane of being surveyed the journal, the gauge outfit of lever amesdial with the outer surface contact of being surveyed the journal.
The lever dial indicator and the half-tile form an integrated structure through the fixing seat, the half-tile is matched and depends on the measured shaft neck, then the gauge outfit of the lever dial indicator is pressed on the surface of the measured shaft neck, the half-tile is slid to read the degree of a pointer on the lever dial indicator, if the reading is interval decimal, the dial plate of the lever dial indicator can be adjusted, and the pointer points to the position of 0. Sliding the half tile to enable the gauge head of the dial indicator to reach the chamfer part of the oil hole, visually detecting whether the reading of the chamfer part of the oil hole is higher than the value of a '0' set by the shaft neck, if the reading is higher than the '0', indicating that a high point exists at the position, and if the reading is lower than the '0', indicating that the high point phenomenon does not exist at the position, wherein the product belongs to a qualified product.
Furthermore, the section of the fixing seat is L-shaped, the dial indicator is connected with one outer side face of the fixing seat, and the half tile is connected with the other outer side face of the fixing seat.
Preferably, the first fastener is a socket head cap screw.
Preferably, the second fastener is a hexagon socket head cap screw.
