Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0019] see figure 1 As shown, according to the embodiment of the present invention, the photoelectric encoder includes a rotating shaft 1, a code disc assembly slidingly sleeved outside the rotating shaft 1, and a photoelectric detection assembly 2 fixedly arranged on the rotating shaft 1, and the code disc assembly is provided with a locking code disc A locking member for the axial position of the assembly on the shaft 1.

[0020] The code disc assembly can slide along the axial direction of the rotating shaft 1, so that the gap between it and the photoelectric detection assembly 2 can be adjusted. The gap meets the requirements to ensure the quality level and accuracy of the encoder disc output signal.

[0021] When adjusting the gap between the code wheel 4 and the photoelectric d...

Abstract

The invention discloses a photoelectric encoder. The photoelectric encoder comprises a rotating shaft (1), a code disk assembly which sleeves the rotating shaft (1) in a sliding mode, and a photoelectric detection assembly (2) which is fixedly arranged on the rotating shaft (1). The code disk assembly is equipped with a locking member used for locking the axial position of the code disk assembly on the rotating shaft (1). According to the photoelectric encoder of the invention, the problem that the gap between the code disk and the photoelectric detection assembly of the photoelectric encoder in the prior art cannot be adjusted is solved.

Description

technical field [0001] The present invention relates to the technical field of encoders, in particular to a photoelectric encoder. Background technique [0002] The photoelectric encoder is a kind of angle measuring equipment integrating light, mechanics and electricity. It converts optical signals into electrical signals through mechanical structure and signal processing circuit, so as to realize the direct or direct measurement of various physical quantities such as diagonal displacement, position and speed. indirect measurement. Among them, the gap control between the code disc and the photoelectric detection component is the core point in the structural design of the encoder, which determines the quality level and accuracy of the encoder output signal. Existing encoder manufacturers mainly rely on improving the processing accuracy of parts to ensure the gap between the code disc and the photoelectric detection component, which has the disadvantages of non-adjustable gap...
