technical field

The utility model relates to a detection device mainly used for detecting displacement sensor errors, in particular to a detection device compatible with various types of displacement sensors.

Background technique

Displacement sensor, also known as linear sensor, is a linear device that belongs to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. Displacement is a quantity related to the movement of the object's position during motion, and the range of displacement measurement methods is quite extensive. Small displacements are usually detected by strain gauge, inductive, differential transformer, eddy current, and Hall sensors, and large displacements are usually measured by sensing technologies such as inductive synchronizers, gratings, capacitive grids, and magnetic grids. Among them, the grating sensor has the advantages of easy digitalization, high precision (currently the highest resolution can reach the nanometer level), strong anti-interference ability, no artificial reading error, convenient installation, and reliable use. be increasingly widely used. At present, the error detection of the displacement sensor still adopts the slider pull ring hook method for error detection. The disadvantage of this error detection is that: due to different products, different installation methods, and different measurement accuracy and range, this error detection will cause every production. One type of displacement sensor needs to be equipped with a corresponding detection equipment, which not only greatly increases the cost input, but also occupies a large area and is very heavy, which is very unfavorable for the development of assembly site debugging work. Secondly, the connection between the slider and the sensor is a soft connection, and it is difficult to accurately judge and adjust the zero position. Especially for the displacement sensor with a bayonet type connection, the existing error detection device is not applicable. In addition, this relatively old-fashioned error detection slide rail has a complicated manufacturing process, and after a long time, the sliding state is unstable, and the displacement cannot be accurately adjusted, resulting in inaccurate readings. How to be compatible with various types of displacement sensor detection, thereby reducing manufacturing costs, and quickly and accurately adjust, adjust the zero position and displacement scale, with higher reliability, has become an urgent problem to be solved in the current displacement sensor error detection.
