Flexible clamping structure of code wheel of reflecting photoelectric encoder

Abstract

The invention discloses a flexible clamping structure of a code wheel of a reflecting photoelectric encoder, relating to the technical field of code wheel clamping of an encoder for solving the technical problems, such as bad temperature adaptability and bad economic efficiency due to adoption of an indium steel code wheel base and the like in the existing code wheel clamping. The flexible clamping structure of the reflecting photoelectric encoder code wheel, disclosed by the invention, comprises a code wheel base and a baffle block; a dual-flexibility hinge rod is designed and processed on the code wheel base; a bonding plate bonded with the code wheel is designed at a suspended end of the dual-flexibility hinge rod; the baffle block is fixedly connected with the code wheel base, does not contact the code wheel, and plays a safety protection role after being degummed, so as to prevent the code wheel from being damaged. The flexible stiffness of the hinge rod is optimized, so that the eccentric stability of the code wheel is ensured, and the temperature adaptability and vibration impact resistance of the code wheel are also improved.

Description

technical field [0001] The invention relates to a code disc clamping technology of an encoder, in particular to a clamping structure for flexible bonding of a reflective photoelectric shaft angle encoder code disc. Background technique [0002] The clamping of the code disc of the encoder usually adopts a pressure plate or bonding. When the pressure plate clamps the code disc, the pressing force of each point cannot be kept completely consistent. Due to the inconsistency of the thermal expansion coefficient of the code disc and the code disc seat, when the temperature changes, it will cause There will be a tendency to slip at the contact position. If the pressure on the pressure plate is too high to hinder the slip, the stress will deform the code disc. When the temperature changes to a certain extent, the stress is greater than the strength limit of the code disc, which will cause the code disc to break; if the pressure If the contact position is not too large, the contact ...
