Description

A kind of slip shaft of list gas circuit structure

Technical field

The utility model is related to lithium battery new energy to batch technical field, more particularly to a kind of slippage of single gas circuit structure Axis.

Background technology

In lithium battery new energy field, slip shaft is applied to batching for the lithium conductive film of lithium battery cutting machine, a kind of high-precision Close winding off spindle belongs to the critical component of cutting machine.Single gas circuit slip shaft at present is the air flue all the way using main shaft as core, Multiple slippage ring elements are mounted on main shaft, and the air of compression enters via main shaft in the expansion set cavity of each slippage ring element, The piston in expansion set cavity is pushed using compressed air, makes to generate friction torque between piston and differential slip ring, is further driven to tiltedly Claw on block is expanded to the outer direction, is squeezed winding barrel, the torque of winding barrel is transmitted, to reach constant tension coiling Effect.Whether gas leakage is to investigate the important indicator of its performance to slip shaft, because it affects winding effect.

Current single gas circuit slip shaft gas tightness is close by the adjacent parts room machine contact progress of differential slip ring Envelope, it requires the required precision of the surface adaptation of each contact part relatively high in this way, easily causes the leakage of assembling slip shaft Gas fraction defective is very high, often reprocesses, and very big in the hidden danger of client gas leakage.

Utility model content

The purpose of this utility model is to provide a kind of slip shafts of single gas circuit structure, to solve to carry in above-mentioned background technology The problem of going out.

To achieve the above object, the utility model provides the following technical solutions：A kind of slip shaft of list gas circuit structure, including Baffle ring, skewback and expansion set, one end of the baffle ring and one end of skewback are rabbeted, and the inside of baffle ring one end is installed with axis It holds, the other end cooperation of the skewback is equipped with expansion set, and the expansion set end face adjacent with skewback is equally spaced and has several work The inside of consent, the piston hole is equipped with piston, and the piston is placed in the air flue inside expansion set, is opened on the inside of the expansion set Equipped with air channel and two grooves, the air channel is located between two grooves, and the inside interlocking of the groove has O-ring, institute The outside for stating skewback is equipped with several to claw, and the external hoop of the skewback has spring.

Further, the bearing is internally provided with spacer.

Further, the surface of the air channel is equipped with several stomatas, and stomata is connected to the air flue in cavity.

Compared with prior art, the utility model has the beneficial effects that：The slip shaft of the list gas circuit structure is in each slippage The structure for being designed as the mode of O-ring air seal in the set of books of ring, while there is mechanical contact to seal, the effect of dual-seal Fruit.The design of the list gas circuit structure, improves confined gas, 100% yields, avoid reprocess it is hidden with potential gas leakage Suffer from.
