Background
In the manufacture of products such as flour sieves, steamers and the like, the peripheral wall portions of these products are usually formed by winding steel strips into a coil and then welding the steel strips. In the process, the steel strip needs to be sequentially subjected to the working procedures of feeding, cutting, winding, clamping and welding. In the winding process, a rotatable chuck is used to clamp the end of the steel strip for winding. In order to adapt to the winding of the steel band ring with smaller diameter, the volume of the clamping head is required to be as small as possible. Therefore, the current clamping heads for welding steel strips are generally driven by a lateral telescopic rod so as to reduce the volume of a clamping head driving mechanism. The structure of the telescopic rod driving chuck is characterized in that the bottom surface of the lower chuck is set to be a driving inclined surface, then a roller is arranged at the end part of the telescopic rod through a U-shaped groove, the roller is in contact with the driving inclined surface, and along with the expansion and contraction of the telescopic rod, the position of a contact point of the roller and the driving inclined surface is changed, so that the lower chuck rises or falls, and the clamping or loosening between the upper chuck and the lower chuck is realized. However, this kind of drive structure through running roller and drive inclined plane movable contact, the running roller is actually the line contact with the drive inclined plane, this kind of line contact is less owing to receive the diameter restriction of telescopic link, lead to the drive structure unstable inadequately, on the other hand, after long-term the use, because reasons such as running roller friction wear or roller axle atress warp, also can lead to further shortening this kind of line contact's length, cause the unstability of drive structure more, make the clamping-force between the corresponding upper and lower chuck in the same stroke of telescopic link become littleer, lead to the steel band to press from both sides tight dynamics and diminish, influence production.
