Device and method for measuring diameter of center-passing circle on blade surface of cutter roller

Abstract

The invention relates to the technical field of measuring devices, in particular to a device and method for measuring the diameter of a center-passing circle on the blade surface of a cutter roller; and the device comprises a to-be-measured part and a measuring substrate, a left-right sliding measuring plate is slidingly arranged on the measuring substrate, and an up-down sliding measuring plate is slidingly arranged on the left-right sliding measuring plate. The up-down sliding measuring plate is slidably provided with a left side sliding measuring plate and a right side sliding measuring plate, the lower side of the up-down sliding measuring plate is slidably provided with a middle sliding measuring plate, the middle sliding measuring plate is rotatably connected with a main auxiliary measuring rod through a middle angle sensor, and the bottom of the main auxiliary measuring rod is provided with a middle main measuring head and a middle auxiliary measuring head; a side edge measuringplate is arranged on the left side sliding measuring plate or the right side sliding measuring plate in a sliding mode in the left-right direction, the side edge measuring plate is rotationally connected with a secondary auxiliary measuring rod through a side edge angle sensor, a side edge main measuring head and a side edge auxiliary measuring head are arranged at the bottom of the secondary auxiliary measuring rod. The device is high in measuring precision and low in cost.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to a measuring device and a measuring method for the diameter of a circle passing through the center of the blade surface of a cutter roll. Background technique [0002] With the continuous improvement of customer requirements and the continuous development of manufacturing technology, the requirements for measurement technology or devices are also getting higher and higher. In the past, some aspects that did not have high requirements for measurement have also begun to increase requirements, such as the measurement of the diameter of the center circle. etc. Originally, the measurement requirements for these aspects were not very high, and only traditional measuring devices such as vernier calipers and hole distance measuring rulers were needed. For example, the hole distance measuring ruler could be used to measure the distance between holes, etc., but Due to the great li...
