Simple rotation shaft coaxiality detection device

Abstract

The invention provides a simple rotation shaft coaxiality detection device which comprises a base; a fixation rod arranged above the base; a transverse rod transversely arranged at the end portion of the fixation rod; a connection mechanism arranged at the end portion of the transverse rod; a dial indicator arranged under the connection mechanism; a sliding plate arranged in the base; fixation blocks fixedly arranged on the sliding plate; a push rod, of which one end is connected with the sliding plate and the other end extends to the outer side of the base; a rotation disc arranged on the base and arranged side by side with the fixation rod; a three jaw chuck arranged on the rotation disc; and a rotation shaft fixedly arranged on the three jaw chuck. The simple rotation shaft coaxiality detection device has the advantages of high precision, excellent use performance, simple structure and long service life.

Description

technical field [0001] The invention relates to a simple detection device for the coaxiality of a rotating shaft. Background technique [0002] Many products and equipment need to use shafts for connection. In order to make the use of the product more convenient, the use of the rotating shaft is also very necessary. For example, on a notebook, the display screen and the body need to be connected by a hinge, which allows the screen to rotate up and down, reduces the overall size, and makes the notebook more convenient to carry. [0003] For this reason, the quality of the rotating shaft is related to the quality of the product itself. If the coaxiality of the rotating shaft cannot meet the requirements, it will be stuck during use. Many of the existing coaxiality inspections use high-end Electronic equipment does have certain guarantees in terms of detection accuracy, but the electronic components used in electronic equipment are very prone to interference and wear, the ove...

If the coaxiality of the rotating shaft cannot meet the requirements, it will be stuck during use. Many of the existing coaxiality inspections use high-end Electronic equipment does have a certain guarantee in terms of detection accuracy, but the electronic components used in electronic equipment are very prone to interference and wear, the overall service life cannot be guaranteed, and the structure is also very complicated
