Abstract
The utility model discloses a tool for measuring the non-circularity of the outer diameter of a plastic pipe, which comprises a dial indicator and a measuring frame for bearing the dial indicator, wherein the pipe is placed between the dial indicator and the measuring frame to measure non-circularity of the pipe via the dial indicator. By using the characteristic of the dial indicator capable of measuring relative value, the dial indicator is fixed on the tailor-made measuring frame to measure the diameter of the pipe, the reading of the dial indicator is the deviation value of the diameter, and the non-circularity value is obtained by the maximum deviation value subtracting the minimum one after repeated measurement in a plurality of positions. Therefore, the shortcomings in the conventional measurement method can be avoided, the measuring method is more convenient and the measurement result is more direct-viewing on the premise that the precision and the accuracy are guaranteed, the deviation condition of the outer diameter of the pipe can be rapidly positioned to further timely adjust extruding equipment, the non-circularity of the pipe can be effectively monitored, and the qualification rate of the product is improved.
