Description

Technical Field

[0001] The utility model relates to the technical field of encoders and hand-cranked wheels, in particular to a connection structure of an encoder and a hand-cranked wheel. Background Art

[0002] Direct connection is the simplest connection method. Usually, the encoder shaft and the hand wheel shaft are connected through a coupling. The function of the coupling is to ensure the concentricity of the two shafts while transmitting the rotational motion of the hand wheel directly to the encoder.

[0003] Currently, linear scales are used on machine tools to measure the travel distance of machine tool worktables. These are measurement feedback devices that utilize the optical principle of a grating. Installed on one side of the guide rail, they take up a lot of space, making them inconvenient to arrange. They are also easily scratched and damaged. Due to the length of the scale, they can easily travel too far, damaging the scale. The grating reader and scale body are also susceptible to moisture, causing reading deviations. This can lead to inaccurate readings over time, and installation takes a long time, requiring professional installation.

[0004] An existing patent (publication number: CN212364881U) discloses a hand-cranked wheel with a magnetic rotary encoder, which includes a positioning disk, a turntable and a transmission shaft. The transmission shaft is provided with a driving gear, the positioning disk is provided with a magnetic rotary encoder, and the magnetic rotary encoder is provided with a driven gear meshing with the driving gear. This utility model hand-cranked wheel with a magnetic rotary encoder can perform encoding measurement, is easy to install, and measures accurate data; it has a compact structure, occupies little space, and is easy to disassemble; it can accurately detect the angle of rotation of the transmission shaft, and can accurately control the stroke of the machine tool by rotating the hand-cranked wheel, and accurately read the stroke data of the machine tool.

[0005] In response to the above problems, existing patents have provided solutions. However, the above solutions have certain limitations during use. If the hand wheel rotates too fast or the load is too large, it may cause instability of the hand wheel and may also damage the encoder, thereby shortening the service life of the encoder and affecting the measurement accuracy.

[0006] Therefore, a connection structure between an encoder and a hand wheel is proposed. Utility Model Content
