Flexible online measuring device for part diameter

Abstract

The invention discloses a part aperture flexibility online measuring device. One side of a working bench is provided with an elevation-type adjustable positioning platform. A central section of the working bench is provided with a guide rail. A bottom portion of a pedestal and the guide rail form a sliding pair via a slide block. A top of the pedestal is provided with a measuring assembly. The pedestal tops of two sides of the measuring assembly are provided with cylindrical pins respectively. One side surface of the pedestal is provided with a connection board. The other side of the working bench is provided with a base. A driving cylinder is arranged on the base. A cylinder rod of the driving cylinder is connected to a connection board on one side surface of the pedestal. By using the device of the invention, through adjusting a positioning block, a flexibility characteristic can be realized; versatility and flexibility are high; the device can be used for multi-specification aperture measuring of parts with various kinds of shapes; after the device is combined with a manipulator, automatic feeding, positioning clamping and automatic measurement of a part aperture can be realized, and on-line measurement can be realized too; corresponding closed loop compensation is performed on a processing system in real time, a production parameter is optimized and a yield is increased.

Description

technical field [0001] The invention relates to a measuring device using a mechanical method, in particular to a flexible on-line measuring device for part aperture. Background technique [0002] Holes are a common feature in mechanical parts and widely exist in various mechanical parts. The machining requirements of many parts are relatively high, and precision measurement is often required after the machining is completed, such as the inner hole of the bearing, the inner hole of the motor end cover, etc. At present, such parts are generally produced continuously in large-scale assembly lines, so the measurement of the hole diameter of the parts is particularly important. [0003] At present, there are two commonly used methods for measuring the aperture of parts: manual measurement and automatic measurement. Manual measurement is to measure parts one by one with manual hand-held measuring tools. Automatic measurement needs to design a set of special fixtures to position...

Problems solved by technology

[0005] 1) When manual measurement is used, the degree of automation is low, and human factors are greatly affected. Manual data recording is used, and the work content of workers is highly repetitive, and it cannot meet the requirements of continuous processing of large-scale assembly lines

[0006] 2) When using automatic measurement, the part aperture measurement mechanism usually uses offline measurement, the measurement data cannot be processed and analyzed in real time, and the production parameters cannot be optimized in real time to guide production practice

[0007] 3) When using automatic measurement, the equipment usually only measures the aperture of one type of parts, the degree of flexibility is low, and the versatility of the equipment is poor. Enterprises need to purchase a variety of measurement equipment, which increases the measurement cost
