Description

TECHNICAL FIELD

[0001] The utility model relates to optical cable cutting fixture technical field especially relates to a kind of positioning fixture for prefabricated optical cable cutting. BACKGROUND

[0002] In the production and processing field of prefabricated optical cable, optical cable cutting is a key process, and its quality directly affects the subsequent use performance and life of optical cable.However, the traditional optical cable cutting mode has many problems in positioning clamping and cutting precision guarantee.In early optical cable cutting operation, simple manual clamping tools such as ordinary bench vise are often used, and the operator manually fixes the optical cable according to experience.This method cannot accurately adjust the clamping force.For thinner optical cable, if clamped too tightly, it is easy to cause damage to the outer skin and internal fiber structure, affecting signal transmission performance.For thicker optical cable, if the clamping force is insufficient, the optical cable is easy to displace during cutting, resulting in deviation of cutting position, increased scrap rate.Although some equipment uses mechanical clamping structure, the clamping assembly design is single and cannot flexibly adapt to the characteristics of different specifications of optical cable.In the guiding link, the traditional equipment often uses simple roller guide or no guiding device.During cutting, the optical cable is easy to deviate due to the influence of cutting force, its own gravity and other factors, making it difficult to ensure cutting precision.During optical cable cutting, the traditional cutting equipment lacks effective tension adjustment mechanism and cannot ensure uniform optical cable tension during cutting.Uniform tension will cause inconsistent stress on the internal fiber of optical cable, which may cause problems such as breakage and unstable signal transmission in subsequent use.Therefore, we propose a positioning fixture for prefabricated optical cable cutting to solve this problem.

[0020] In this embodiment, two sets of guide plates 808 are fixedly installed on the top of each of the two sets of fixing frames 801.
