Problems solved by technology
[0002] At present, blade forgings are traditionally tested using a vertical frame measuring tool, which generally consists of a testing template, a thimble, and a vertical frame. The size of the blade is judged by light transmission. This detection method completely relies on human judgment when positioning, which has low precision and poor accuracy, and it is time-consuming when positioning and measuring the blade.

The invention discloses a blade forging dial gauge horizontal detection device which comprises a base which is provided with a positioning assembly, wherein a blade forging is horizontally fixed to the base through a positioning component, the base is correspondingly provided with a plurality of back arc dial gauge template frames and inner arc dial gauge template frames at two sides of the blade forging, the base is provided with a longitudinal displacement detection frame corresponding to the blade root back arc inner edge panel of the blade forging, the base is provided with horizontal displacement detection frames corresponding to two diagonal lateral surfaces of the blade root of the blade forging, the back arc dial gauge template frames, the inner arc dial gauge template frames, the longitudinal displacement detection frame and the horizontal displacement detection frames are equipped with dial gauges for detecting the blade forging. According to the blade forging dial gauge horizontal detection device, the positioning and detection efficiency are greatly improved, and the detection precision and accuracy are obviously improved.
Description
technical field [0001] The invention belongs to blade forging detection technology, in particular to a blade forging dial gauge horizontal detection device. Background technique [0002] At present, blade forgings are traditionally tested using a vertical frame measuring tool, which generally consists of a testing template, a thimble, and a vertical frame. The size of the blade is judged by light transmission. This detection method completely relies on human judgment when positioning, which has low precision and poor accuracy, and it is time-consuming when positioning and measuring the blade. For this reason, it is imminent to improve the detection efficiency, precision and accuracy of forgings, especially precision forgings. Contents of the invention [0003] The object of the present invention is to provide a horizontal detection device for a blade forging dial indicator, which has the characteristics of high detection efficiency, high precision and good accuracy, so as...
