Jacket type center frame clamp of numerical control equipment

Abstract

The invention provides a jacket type center frame clamp of numerical control equipment. The jacket type center frame clamp comprises a clamp base, an end cover, a jacket seat, a jacket, bearings, a piston, an oil cylinder body and a rear cover, a mounting base is arranged on the clamp base, the jacket seat and the oil cylinder body are mounted at the two ends of the mounting base through the bearings respectively, the end cover is arranged at one end, back to the oil cylinder body, of the outer side of the jacket seat, the rear cover is arranged at the end, back to the jacket seat, of the outer side of the oil cylinder body, an oil cavity is formed in the end, facing the jacket seat, of the oil cylinder body, the oil cylinder body is further provided with an oil inlet channel opening P, an oil inlet channel opening T and an oil return channel which communicate with the oil cavity, the piston is arranged in the oil cavity, the jacket is installed at the end, facing the end cover, of the piston, and the jacket is arranged in an inner cavity of the jacket seat. Compared with an existing center frame, the clamp can be installed on an existing numerical control machine tool, universality is high, surrounding type clamping is achieved, part deformation is extremely small, the machining precision is improved, and the qualified rate of products is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of fixtures, in particular to a jacket-type center frame fixture for numerical control equipment. 【Background technique】 [0002] Thin-walled pipe parts generally appear in the military and aerospace fields. The processing of thin-walled parts has always been a difficult problem. Among them, the external turning thread processing is the most difficult. The ordinary clamping method can easily cause deformation of the parts during processing, which in turn affects Manufacturing precision of parts. With the continuous development of the manufacturing industry in the military and aerospace fields, the requirements for the manufacturing precision of thin-walled tube parts are also getting higher and higher. The current processing method is to clamp one end with an ordinary chuck and the other end to clamp the outer circle with an ordinary center frame to process the thread. However, due to excessive pressure, ...

AI Technical Summary

Problems solved by technology

The current processing method is to clamp one end with an ordinary chuck, and the other end uses an ordinary center frame to clamp the outer circle, so as to process the thread. However, due to excessive pressure, the thread after processing will be deformed, which cannot meet the design requirements, resulting in scrap.
