Abstract

The invention belongs to the technical field of fixtures, specifically a self-centering fixture for ceramic cylinder liner grinding, including a rotating shaft, a clamping device, a support frame, a motor and a connecting rod; the invention drives the rotating shaft to rotate through a motor, The rotating shaft drives the second turntable to move along the axial direction of the rotating shaft through the thread. The threads on the rotating shaft are left-handed threads and right-handed threads respectively, so that the second turntable moves to the first turntable; during the process, the second turntable squeezes the elastic spokes, The elastic spokes are bent toward the inner wall of the ceramic cylinder liner, and the middle part of the elastic spokes squeezes the inner wall of the ceramic cylinder liner to realize the clamping of the ceramic cylinder liner. By using the elastic spokes to clamp the ceramic cylinder liner, the elastic spokes contact the inner wall of the ceramic cylinder liner more easily. Tight, to avoid damage to the ceramic cylinder liner during the clamping process. After the elastic spokes are pressed against the inner wall of the ceramic cylinder liner, the elastic spokes are elastic as a whole, which prevents the ceramic cylinder liner from being impacted during processing and avoids damage to the ceramic cylinder liner.

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...
