Abstract

The invention belongs to the technical field of tool clamps, and particularly relates to a self-centering clamp for grinding a ceramic cylinder sleeve. The self-centering clamp comprises a rotating shaft, a jacking device, a supporting frame, a motor and a connecting rod. According to the self-centering clamp, the motor drives the rotating shaft to rotate, the rotating shaft drives a second rotating disc to move in the axial direction of the rotating shaft through threads, and the threads on the rotating shaft are left-handed thread and right-handed thread respectively, so that the second rotating disc moves to a first rotating disc; in the process, the second rotating disc extrudes elastic spokes, the elastic spokes are bent towards the inner wall of the ceramic cylinder sleeve, the middle portions of the elastic spokes extrude the inner wall of the ceramic cylinder sleeve, and the ceramic cylinder sleeve is clamped; and the elastic spokes are used for clamping the ceramic cylinder sleeve, so that the elastic spokes contact the inner wall of the ceramic cylinder sleeve more closely, the ceramic cylinder sleeve is prevented from being damaged in the clamping process, the elastic spokes are tightly pressed against the inner wall of the ceramic cylinder sleeve, the elastic spokes are integrally elastic, impact force is avoided in the machining process of the ceramic cylinder sleeve, and damage to the ceramic cylinder sleeve is avoided.

Description

technical field [0001] The invention belongs to the technical field of fixtures, in particular to a self-centering fixture for ceramic cylinder liner grinding. Background technique [0002] With the continuous expansion of human exploitation of global oil and gas resources, and it is getting worse and worse, a large number of metal cylinder liners are frequently replaced. Even so, it is difficult to ensure the high pressure and wear requirements of drilling rigs. Zirconium, zirconia toughened alumina (ZTA), high-performance A-99 alumina ceramics three major material systems. Its raw materials are made of high-purity nano-zirconia and alumina micropowder, which are formed by advanced cold pressing technology, sintered at high temperature, assembled, and finally polished with high precision. It has high flexural and tensile strength, high Fracture toughness and acid and alkali corrosion resistance. [0003] Due to the high bending resistance and tensile strength of ceramic c...
