CPT has obtained a patent for shaft locking equipment for optical axis measurement equipment

Shenzhen CPT Precision Technology Co., Ltd. has obtained a patent for a shaft locking device for optical axis measurement equipment, with publication number CN118913107A and application date of October 2024.

The patent abstract shows that the present invention discloses a shaft locking device for optical axis measurement equipment. The present invention relates to the field of optical measurement technology and includes a base. A bearing is rotatably sleeved on the central axis of the base, and a bearing is fixedly attached between the bearing and the base. A gear ring is fixedly attached to the inner surface of the base, and a friction pad is slidably sleeved on the top surface of the base. The top surface of the bearing is provided with a through hole, and the inner surface of the through hole is provided with a sliding groove. The side wall of the sliding groove is provided with a first sealed chamber. The advantage of the present invention is that the shaft system can be fixed while the measuring equipment is fixed, so that the fixing of the shaft system and the fixing of the measuring equipment can work together without the need to follow the steps sequentially. Shortened the measurement cycle and made the installation of optical axis measuring equipment simple, And the heavier the optical axis measuring equipment, the smaller the limit friction force, avoiding damage to the shaft system caused by friction force, while the lighter the optical axis measuring equipment, the greater the limit friction force, fully avoiding the movement of the optical axis measuring equipment.
