A device for detecting the finished size of shaft forgings

Abstract

A device for detecting the size of a shaft forging finished product of the present invention comprises a bottom plate, an electric slide rail is fixed on the bottom plate, two three-jaw chucks are arranged on both sides of the top of the electric slide rail, two three-jaw chucks The chucks are respectively used to clamp the two ends of the shaft forging. Each of the jaws of the three-jaw chuck is provided with a storage slot that runs through the jaws, and a clamping device slides in the storage slot. block, when the three jaws of the three-jaw chuck approach each other to clamp the shaft forging, it is the clamping block on each of the jaws that finally plays a clamping effect, because the clamping block The uniform distribution makes the protrusion or depression on the shaft forging have no influence on the clamping effect of the three-jaw chuck.

Description

technical field [0001] The invention relates to the related field of shaft detection, in particular to a device for detecting the size of a shaft forging finished product. Background technique [0002] Shafts are a kind of metal workpieces commonly used in machinery. According to different uses, shafts are divided into key shafts, stepped shafts, and crankshafts. Many of the larger shafts are produced by forging, especially stepped shafts and stepped shafts. , although the forging production speed is relatively fast, the size of the shaft produced by forging, or even the shaft after turning, may have deviations. Therefore, the size of the shaft forging should be checked frequently to ensure the quality of the finished product In the existing detection methods, either through physical detection or grating detection, but the two detection methods usually move along the longitudinal direction on the shaft forging, although the accuracy of the detection results is guaranteed In...

[0002] Shafts are a kind of metal workpieces commonly used in machinery. According to different uses, shafts are divided into key shafts, stepped shafts, and crankshafts. Many of the larger shafts are produced by forging, especially stepped shafts and stepped shafts. , although the forging production speed is relatively fast, the size of the shaft produced by forging, or even the shaft after turning, may have deviations. Therefore, the size of the shaft forging should be checked frequently to ensure the quality of the finished product In the existing detection methods, either through physical detection or grating detection, but the two detection methods usually move along the longitudinal direction on the shaft forging, although the accuracy of the detection results is guaranteed In fact, the detection efficiency is low, it is not suitable for large-scale detection, and it is also a record of data, the detection results are not intuitive, and follow-up processing is required, which is troublesome, and in the clamping process of the existing shaft forging detection , it is difficult to judge whether the clamping part is protruding or concave, so that the clamping center cannot be aligned with the center of the shaft forging, resulting in inaccurate subsequent detection results
