Abstract

The invention belongs to detection equipment for shaft parts and provides a transmission measuring device for dimension measurement of the shaft parts. The transmission measuring device solves the problems that existing dimension measurement equipment based on machine vision is inconvenient to use and low in accuracy. The transmission measuring device comprises a horizontal base, a support, a visual system, a stepping motor, a ball screw, a sliding table and a locating fixture. The support is perpendicularly fixed to the horizontal base. The visual system is fixed to the support. The ball screw is located between two stand columns of the support. The sliding table is fixedly connected with a sliding block of the ball screw. The stepping motor is connected with the ball screw through a coupler. Components of the locating fixture are fixed to the end of the sliding table and the end of the ball screw respectively. The locating fixture is used for locating and clamping a shaft. The shaft parts conduct rectilinear motion below the visual system. Long shaft parts can be measured just through one industrial camera. The transmission measuring device has the advantages of high efficiency, stability and high accuracy, and can greatly lower the labor intensity of workers, improve production efficiency and avoid human caused errors in the measuring process.

Description

technical field [0001] The invention belongs to testing equipment for shaft parts, in particular to a transmission measuring device for dimension measurement of shaft parts, especially for measuring the length and diameter of washing machine shaft parts. Background technique [0002] Traditional washing machine shaft parts include the washing shaft shown in Figure 1(a) and the transmission shaft shown in Figure 1(b), and their dimensions are usually measured with a vernier caliper or a screw micrometer, or judged with a special inspection tool Whether their dimensions are acceptable or not, measurements cannot be given. These two measurement methods are manual measurement. When the measurement quantity is large, due to the high intensity of manual work, it is easy to cause visual fatigue, resulting in errors and low efficiency. [0003] The invention patent with the application number 201110419626.2 is a dimension measuring device based on machine vision. It is inconvenient...
