Abstract

The invention discloses a rotary and rapid positioning device. The rotary and rapid positioning device is characterized by comprising a positioning central spindle, wherein the positioning central spindle is arranged in the center of a base and sleeved with a rotary ring, a small ring gear of the rotary ring is in contact connection with a lower pressing circle through a roller needle bearing, a large ring gear of the rotary ring is in contact connection with a roller needle, the roller needle is connected with a supporting block on the base, a positioning ring gear is arranged on the outer side of the large ring gear of the rotary ring, the positioning ring gear is connected with the base through a hydraulic jack, and the large ring gear is matched with the positioning ring gear. The rotary and rapid positioning device has the advantages of being simple in structure, low in manufacturing cost, convenient to operate, high in production and machining efficiency and the like, and can clamp and position large-scale boring mill and drilling machine parts and rapidly and accurately position workpieces in a rotating mode. The product machining precision is determined by the number of teeth of the rotary ring. Whether an electric transmission mechanism needs to be added or not is judged according to actual use demands. The rotary and rapid positioning device has high practicability and can be brought into use in manufacturing shops on a large scale.

Description

technical field [0001] The invention relates to a fast rotating positioning device, which can be used for clamping and positioning parts of large boring machines and drilling machines. Background technique [0002] At present, for the machining operation of large rotary parts, workshop operators usually manually rotate (clamp) and position the parts on the boring machine platform. When processing a part, manual operation is required, and the labor force is quite large. The requirement of high precision cannot be achieved through simple artificial measuring equipment, the positioning accuracy of the parts is poor, the size deviation of the processed parts is large, and the production efficiency of this method is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fast rotating positioning device with simple structure, low manufacturing cost, convenient operation, high production efficiency and high processing ...
