Description

Technical Field

[0001] The utility model relates to the technical field of encoders, in particular to a hollow magnetic encoder. Background Art

[0002] An encoder is a device that compiles and converts signals or data into a signal form that can be used for communication, transmission and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code disk and the latter is called a yardstick. According to the readout method, encoders can be divided into contact and non-contact types; according to the working principle, encoders can be divided into incremental and absolute types. The incremental encoder converts the displacement into a periodic electrical signal, and then converts the electrical signal into a counting pulse, and the number of pulses is used to indicate the size of the displacement. Each position of the absolute encoder corresponds to a certain digital code, so its indication is only related to the starting and ending positions of the measurement, but not to the intermediate process of the measurement.

[0003] For example, the utility model with application number 202122366244.X discloses a new hollow magnetic encoder, which has a high structural strength and is stable and reliable by setting an integrated base and support. The nuts and screws connected to the outer end of the encoder can be directly installed on the upper end of the support, and the positioning blocks and EVA pads fixed at the bottom of the encoder can be accurately and tightly positioned and installed on the upper end of the support, which can buffer and reduce shock, facilitate quick disassembly and assembly, have a simple structure, and low cost, and improve the detection stability of the magnetic encoder. The drive shaft set in the middle of the bottom of the encoder can facilitate the rotation control inside the base of the hollow structure, and the design is reasonable. The mounting plate and the bonded rubber pad fixed on the top of the drive shaft make disassembly and assembly more convenient, safe and practical.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This new hollow magnetic encoder facilitates installation through nuts and screws, but only using nuts and screws to complete the installation does not provide good firmness, the installation of the mounting bracket is not very stable, and the practicality is poor and cannot meet people's use needs.

[0006] Therefore, a hollow magnetic encoder is designed to optimize the above problems. Utility Model Content

The mounting ring is placed in the card slot at the top of the limiting ring, and the fixing slot inside the mounting ring is aligned with the stopper inside the card slot, so that the stopper and the fixing slot overlap with each other. When the mounting ring is placed at the lowest end inside the card slot and then the mounting ring is rotated until the stopper and the fixing slot are staggered, the mounting ring and the limiting ring are then installed by bolts through the mounting holes. The top of the mounting ring can be limited and fixed at multiple positions without adding bolts and other components to increase the complexity of operation, so the purpose of improving the firmness of the installation and facilitating the operation is achieved, thereby facilitating the workers.
