Automatic detecting, correcting and machining tool for bent shaft fine grinding

Abstract

The invention discloses an automatic detecting, correcting and machining tool for bent shaft fine grinding. The automatic detecting, correcting and machining tool comprises a bent shaft fixing devicefor containing a double-deflected-core bent shaft, a side pressing tool used for clamping the double-deflected-core bent shaft, a deflected core positioning device for positioning the double-deflected-core bent shaft, a rotation mechanism for rotating the double-deflected-core bent shaft, and a detection device for detecting the outer diameter size of the deflected core part in the double-deflected-core bent shaft. The bent shaft fixing device, the deflected core positioning device and the rotation mechanism are sequentially arranged from left to right. The side pressing tool is arranged abovethe bent shaft fixing device, and the detection device is arranged on one side of the bent shaft fixing device. The automatic detecting, correcting and machining tool can be matched with a mechanicalarm to be used, automatic production is achieved, the included angle is controlled within 0.07 mm after double-deflected-core fine grinding, and the reject ratio of the type of product is reduced; stability during product production is improved, it is guaranteed that equipment can stably run, and the CPK value is improved; and the usage difficulty is lowered for operators and equipment maintenance personnel.

Description

technical field [0001] The invention relates to a tooling for automatic detection, correction and processing of crankshaft fine grinding, which belongs to the technical field of crankshaft fine grinding. Background technique [0002] Such as figure 1 As shown, the double eccentric crankshaft 1 is mainly composed of five parts: the crankshaft tail 11 , the crankshaft main shaft 12 , the first crankshaft eccentric 13 , the second crankshaft eccentric 14 and the crankshaft countershaft 15 . Since the two eccentrics of the crankshaft will have an included angle due to various factors during the machining process, in order to ensure its use effect, it is required that the included angle reflected in the left and right yaw distance of the maximum outer diameter of the eccentric should not be greater than 0.07mm. [0003] At present, in the existing automatic production and development process of double eccentric crankshaft finishing, because the eccentric angle does not meet the ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the existing automatic production and development process of double eccentric crankshaft finishing, because the eccentric angle does not meet the requirement of a spacing of less than 0.07mm, the defective rate of products is greater than 8%, and the process capability index CPK value is extremely unstable. The quality control is very difficult, the shared cost is high, the waste is large, and the enthusiasm of employees is low
