Drilling machining positioning component for engine crankshaft bearing cover

Abstract

The invention relates to a drilling machining positioning component for an engine crankshaft bearing cover. The drilling machining positioning component comprises multiple supporting bottom posts which are fixed on the upper surface of a base at intervals, a material bearing substrate which is slidably arranged on the supporting bottom posts, a bearing cover clamp which is slidably arranged on thematerial bearing substrate, a material guiding plate which is arranged on the side surface of the bearing cover clamp, limiting slide rails which are fixed on the outer side surfaces of the supporting bottom posts and supporting slide blocks which are slidably arranged on the limiting slide rails; the upper ends of the supporting slide blocks extend and are fixed on the bottom of the material bearing substrate; and the sliding direction of the bearing cover clamp on the material bearing substrate is vertical to the sliding direction of the material bearing substrate on the supporting bottom posts. Therefore, precise control of the bearing cover clamp in two directions can be realized; and the bearing cover clamp is precisely positioned and fixedly clamped.

Description

technical field [0001] The invention relates to a positioning assembly, in particular to an engine crankshaft bearing cover drilling processing positioning assembly. Background technique [0002] The existing crankshaft bearing cap needs to have a marking mechanism that can distinguish the correct assembly direction and facilitate correct assembly and number marking and necessary mounting holes. The above-mentioned marks or holes are generally placed on the top surface of the crankshaft bearing cap. The top surface of the crankshaft bearing cap is arc-shaped, which is inconvenient for processing on the one hand, and inconvenient to identify on the other hand, which will cause the slip groove to fail to connect when the bearing shell is assembled in the final assembly, resulting in irreversible serious quality accidents and economic losses ; Therefore, it is necessary to design the corresponding engine crankshaft bearing cap drilling and positioning assembly.
