钻头角度测量仪,是一种新型简便的测量钻头各部角度的专用量具。它与国内目前常用的钻头角度测量工具(样板测量、钢板尺近似测量、百分表测量及万能角度尺测量)相比,具有结构简单、使用方便、定位比较可靠、测量范围广等特点。测量仪上装有带游标的指示盘,观察角度值的精度为30′。一、结构:测量仪由两组V型块及主体、指示盘和盖板等五种零件组成(图1)。两V型块分别与主体用螺钉连接固定,指示盘嵌入主
Bits angle measuring instrument, is a new type of simple and convenient measurement of the various angles of the drill bits. Compared with the commonly used tools for bit angle measurement in the country (template measurement, approximate measurement of steel ruler, dial indicator and universal angle ruler), the utility model has the advantages of simple structure, convenient use, reliable positioning and wide measuring range. The measuring instrument is equipped with a cursor indicator plate, the value of the observed angle accuracy of 30 ’. First, the structure: Measuring instrument consists of two V-blocks and the main body, indicating plate and cover five parts (Figure 1). Two V-block were connected with the main body with a screw, indicating disk embedded in the main
