Measuring device during machining of cylindrical grinder

Abstract

The invention discloses a measuring device during the machining of a cylindrical grinder, which comprises a measurement main body, a measuring head, an adjusting device of the measuring head, a dial gauge and an adjusting device of the dial gauge. The device comprises the key points that: the dial gauge is vertically arranged on a dial gauge fixing rod of the main body through locking screws; the dial gauge adjusting rod is fixed at the tail end of a movable sleeve of a measuring rod through clamp nuts to keep concentric with the center line of the dial gauge; the movable sleeve of the measuring rod is arranged on the upper part of the measurement main body through a pin shaft; the measuring rod is fixedly arranged in the movable sleeve of the measuring rod through the locking screws; the measuring rod is integrated with the movable sleeve to move up and down by taking the pin shaft as the centre of a circle; a measuring head up-down adjusting arm fixed on the measuring rod through clamp screws is inserted into the lower end of the measuring rod; the measuring head is fixed at the lower end of the adjusting arm through the locking screws; and the whole measuring device is fixedly arranged at the corresponding position of a machine body through main body fixing screws. The measuring device has the advantages of simple structure, convenient measurement, high precision, scrap rate reduction and labor intensity reduction.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device for dimension tolerance, shape tolerance, etc. of workpieces in the processing of cylindrical grinding machines. Background technique [0002] In the current cylindrical machining process, especially in the cylindrical grinding process, in order to ensure the required high precision, repeated measurements are required. For small-diameter external circles, measuring tools can be used to directly clamp the external circle for measurement. Although it is convenient, it cannot guarantee the accuracy of the measurement. For the outer circle with a large diameter, it is inconvenient to directly clamp the outer circle with a measuring tool. The uniformity and stability of the workpiece size increases the scrap rate and labor intensity.

Problems solved by technology

[0002] In the current cylindrical machining process, especially in the cylindrical grinding process, in order to ensure the required high precision, repeated measurements are required. For small-diameter external circles, measuring tools can be used to directly clamp the external circle for measurement. Although it is convenient, it cannot guarantee the accuracy of the measurement. For the outer circle with a large diameter, it is inconvenient to directly clamp the outer circle with a measuring tool. The uniformity and stability of the workpiece size increases the scrap rate and labor intensity

[0003] The Chinese utility model patent with the current notification number CN201203398 disclosed a comprehensive measuring instrument for the outer diameter of the piston on March 4, 2009. This utility model solves the problems of low precision and poor stability of the current measuring device. Its structure is as follows: it includes a bottom plate, and a positioning block is arranged on both sides of one end of the bottom plate, and a fixed vertical plate is installed by positioning the positioning block, and a measuring vertical plate composed of a large measuring vertical plate and a small measuring vertical plate is installed on the opposite side of the fixed vertical plate. The measuring vertical plate is connected with the adjustment device; the measuring flat plate is installed between the fixed vertical plate and the measuring vertical plate, and the side head device is installed on both the fixed vertical plate and the measuring vertical plate; the sensor frame is installed on the bottom plate on one side of the measuring vertical plate, The dial indicator and the dial indicator are installed on the sensor frame; the dial indicator and the small measuring vertical plate, and between the dial indicator and the large measuring vertical plate are slid and fitted through the adjustment device to obtain the measured value

Although this structure solves the problem of high measurement accuracy, the structure is complex and it is inconvenient to measure the outer circle during processing. Therefore, it is necessary to provide a simple structure, convenient measurement, high precision, and reduce scrap rate and labor. In-process measuring device for strength on cylindrical grinder
