Abstract

The invention provides an indexing and positioning device, and belongs to the technical field of machining. The indexing and positioning device comprises an output shaft, a rack, a gear, a pawl, a ratchet, positioning blocks and a positioning disc; the ratchet is coaxially fixed on the output shaft; the gear is rotationally arranged on the output shaft; the pawl is mounted on the end surface of the gear; the pawl and the ratchet are engaged; the output shaft is coaxially fixed with the positioning disc; positioning grooves are formed in the positioning disc at equal intervals; the positioning blocks matched with the positioning grooves are arranged at the lower end of a first double-end piston rod of a first oil cylinder; a first trigger block is arranged at the upper end of the first double-end piston rod; a disc fixture is coaxially mounted on one side of the output shaft; a rack of a second oil cylinder is mounted on one side of a second double-end piston rod; the gear and the rack are engaged; and a second trigger block is arranged at the other end of the second double-end piston rod. The indexing and positioning device realizes indexing and positioning of shaft workpieces, facilitates radial porous machining of the shaft workpieces, and is reasonable in structure and high in reliability.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to an indexing and positioning device. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing method, it can be divided into cutting processing and pressure processing. The technological process can be divided into casting, forging, stamping, welding, machining, assembly and other technological processes. The technological process is composed of one or several sequentially arranged processes, and a process is composed of several working steps. The machines required for processing include digital display milling machines, digital display forming grinders, digital display lathes, EDM machines, universal grinders, machining centers, external cylindrical grinders, internal cylindrical grinders, precision lathes, etc., which can be used for turning, milling...
