Background The spinning rubber roller is a key component commonly used in textile machinery, and the machining quality of inner chamfers at two ends of the spinning rubber roller directly influences the assembly precision and the service life of the rubber roller. When the textile rubber roller is subjected to inner chamfering, the textile rubber roller is required to be clamped and fixed so as to ensure the stability and the precision in the processing process. At present, the existing equipment adopts an external clamping type clamping mode to fix the rubber roller, namely, the surface of the rubber roller is directly clamped from the outside through clamping jaws or arc clamping plates. However, the clamping force in the clamping mode directly acts on the outer wall of the rubber roller, so that the rubber roller is easy to deform radially, and particularly, for the rubber roller with a thinner wall thickness or softer material, the deformation risk is higher, and the service performance of the rubber roller is influenced. To solve the above problems, some devices have attempted to support the rubber roll from inside before clamping to enhance the deformation resistance of the rubber roll during processing. However, the existing internal support structure has the defects that firstly, the connection stability between the internal support and the inner wall of the rubber roller is poor, relative sliding is easy to occur in the processing process, chamfering operation is influenced, secondly, the feeding and the withdrawing of the internal support structure depend on manual operation, the automation degree is low, and effective linkage with the working procedures of external clamping, processing, discharging and the like is difficult to form, so that the integral processing efficiency is influenced.
