Roundness control tool for stripe ring

Abstract

The invention discloses a roundness control tool for a stripe ring. The roundness control tool comprises an end face milling tool and a vertical face milling tool. The end face milling tool comprises a base, a fixing plate and a supporting plate. A sliding groove is formed in the base. The supporting plate is connected to the sliding groove in a sliding manner. The fixing plate is fixed to the base. Notches are formed in the two ends of the upper portion of the fixing plate respectively. First circular arc benchmark faces are formed by the bottom faces of the notches, and end face benchmark faces are formed by the side faces of the notches. Second circular arc benchmark faces are formed at the two ends of the upper portion of the supporting plate respectively. The fixing plate and the supporting plate are parallel. The notches are formed in the plane, back to the supporting plate, of the fixing plate. The vertical milling tool comprises a splicing plate and a plurality of joint plates. The surface of the splicing plate is provided with protruding circular ring guide rails, and arc guide grooves are formed in the joint plates. The joint plates are connected to the splicing plate in a sliding manner, and the circular ring guide rails are located in the arc guide grooves. The end face milling tool and the vertical face milling tool are used for installing and fixing stripe blocks to be machined for milling, and the machining precision of the stripe ring is improved.

Description

technical field [0001] The invention relates to tire manufacturing equipment, in particular to a tool for controlling the roundness of tread rings. Background technique [0002] In the tire industry, the pattern circle is usually assembled from multiple pattern blocks. After the pattern circle is cast, each pattern block has to go through processes such as cutting, milling, and rounding to ensure the roundness accuracy of the pattern circle after assembly. , while the accuracy of rounding mainly depends on the flatness and verticality of the façade of each pattern block. [0003] In the conventional process, after the pattern ring is cut, the facade of each pattern block is processed by processing equipment (general milling, five-axis machining). Due to multiple clamping and positioning during processing, the facade of each pattern block The accuracy of flatness cannot guarantee uniform dimensional accuracy, and the control of the reserved gap value of the whole circle when...
