Comprehensive inspection device for measuring position of crankshaft hole

Abstract

The invention discloses a comprehensive inspection device for measuring the position of a crankshaft hole. The comprehensive inspection device comprises a crankshaft output end detecting and supporting part, a crankshaft small-head end detecting and supporting part, a prepositioning support, a crankshaft first connecting rod shaft journal positioning mechanism and a bottom plate, wherein the crankshaft output end detecting and supporting part is matched with a crankshaft output end; the crankshaft small-head end detecting and supporting part is matched with a crankshaft small-head end; the prepositioning support and the crankshaft first connecting rod shaft journal positioning mechanism is arranged between the crankshaft output end detecting and supporting part and the crankshaft small-head end detecting and supporting part; and the crankshaft output end detecting and supporting part, the crankshaft small-head end detecting and supporting part, the prepositioning support and the crankshaft first connecting rod shaft journal positioning mechanism are fixedly arranged on the bottom plate. The comprehensive inspection device has the characteristics of high universality and operation convenience, the working efficiency of detecting the position of the crankshaft hole can be obviously improved, the detection cost is reduced, and high economic benefits are brought to an enterprise.

Description

technical field [0001] The invention relates to a measuring tool for an engine crankshaft, which is especially suitable for detecting the position degree of hole systems at both ends of the engine crankshaft, and belongs to the technical field of engines. Background technique [0002] The crankshaft is the key component of the power output of the automobile engine. During the working process of the engine, the crankshaft is subjected to the joint action of the periodically changing gas pressure, the centrifugal force of the rotating mass, the reciprocating inertial force and the torque generated by them. In order to ensure the reliability of the crankshaft, in addition to requiring the crankshaft to have sufficient strength and rigidity, the machining accuracy of the crankshaft must also be strictly controlled. [0003] At present, in the crankshaft machining process, three-coordinate detectors or crankshaft-specific inspection tools are generally used to detect the posit...

AI Technical Summary

Problems solved by technology

[0003] At present, in the crankshaft machining process, three-coordinate detectors or crankshaft-specific inspection tools are generally used to detect the position of the hole system at both ends of the crankshaft. Due to the long three-coordinate detection cycle and low work efficiency, the overall beat of crankshaft production is affected; and by When the crankshaft special inspection tool is used to detect the position of the hole system at both ends of the crankshaft, it is necessary to set up special inspection tools for different types of crankshafts, which increases the cost of inspection
