An inspection equipment for product size and deformation

Abstract

The invention provides a device for automatically detecting product size and deformation. The device includes a program control station and an automatic detection platform. The program control station includes a touch screen and an industrial control computer display. The automatic detection platform includes an automatic telescoping cylinder, a sensor and a protection apparatus for the sensor, a profile constructing platform, an electric slide rail and protection covers. The above of the automatic telescoping cylinder is connected to a displacement sensor, and the below of the automatic telescoping cylinder is connected to the profile constructing platform. The automatic telescoping cylinder can move up and down, and front and back. The above of the profile constructing platform is secured to the electric slide rail and may move left and right. The outside of the displacement sensor is provided with two guide posts which are axially symmetrical and are wrapped by fixed torque springs. The upper end of each guide post is connected to a supporting plate. The outside of the displacement sensor, the guide posts, and the profile constructing platform are provided with the protection covers. According to the invention, the device uses the automatic telescoping cylinder and the displacement sensor to automatically measure the size and deformation of the product, thus having high detection accuracy, efficiency, easy operation and high result accuracy.

Description

technical field [0001] The invention belongs to the field of product testing, and in particular relates to a testing device for product size and deformation. Background technique [0002] After the FRP parts are produced, it is usually necessary to inspect the important assembly dimensions such as the size and arc surface of the product. At present, conventional measuring instruments such as tape measure and caliper are usually used to measure the size of FRP parts in the market, while the curved surface and other important assembly dimensions that cannot be detected intuitively need to be detected through specially processed inspection samples, and the processing cost of inspection samples Raw material costs, processing fees, labor hours, and processing and inspection samples and manual inspection are likely to cause large errors in the test results. [0003] At present, the methods for detecting the size and deformation of products in the patents applied for in China main...

Problems solved by technology

Both of the above two patents use an automated measurement method, using sensors to measure the deformation of the product, but the position of the sensor is fixed and can only measure the deformation of a specific position of the product, and the shape and size of the measured product limited
