Description

Spring detection mechanism

technical field

Background technique

A spring is a mechanical part that uses elasticity to work, deforms under the action of an external force, and returns to its original shape after the external force is removed. It is generally made of spring steel. The types of springs are complex and diverse. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc.

For the coil spring, after it is produced, it is necessary to test its elastic force and displacement to ensure that the elastic force of the coil spring meets the requirements when it is compressed to a certain displacement. The traditional method is to place the spring in a jig with a scale, and make one end of the spring fixed, and then the worker presses the pressure sensor against the other end of the spring. When the spring is compressed to a specified distance, observe the pressure. The reading of the sensor is used to complete the detection of the elastic force and displacement of the spring.

However, this detection method has the following problems. When the worker pushes the pressure sensor, the pressure sensor will shift, resulting in a deviation in the detected elastic force, so there is a certain error in the spring force and displacement detection of the spring; secondly, the spiral Springs have different sizes. For springs with high elastic force, the traditional detection method cannot effectively compress the spring, so it cannot meet the requirements for testing high elastic spring springs. Therefore, in order to solve the above technical problems, the spring detection mechanism of the present application is proposed.
