Abstract

The invention relates to an electric-gas hybrid type piston cylinder structure. The electric-gas hybrid type piston cylinder structure comprises a cylinder body and is characterized in that the end ofthe cylinder body is provided with a front end cover and a rear end cover, an inner cavity of the cylinder body is provided with an air cylinder rod and an air cylinder piston, and the front end cover and the rear end cover seal the two ends of the cylinder body; the rear end of the air cylinder rod is fixedly connected with the air cylinder piston, the front end of the air cylinder rod penetrates through the front end cover and then is exposed outwards to form a connecting end head, an air inlet end opening and an air outlet end opening are formed in the front end cover and the rear end cover correspondingly and communicate with an inner cavity of the cylinder body, and an air piston cylinder structure is formed; the air cylinder rod is a hollow rod body, a ball screw is arranged in an inner cavity of the air cylinder rod, a motor is arranged on the outer side of the rear end cover, a rotating shaft of the motor penetrates through the rear end cover and is connected with the ball screw, and the rear end of the ball screw is connected with a feed screw nut in a threaded mode, the feed screw nut is fixedly connected with the rear end cover, an axial ventilating hole is formed in the feed screw nut, and an electric piston cylinder structure is formed; and the electric-gas hybrid type piston cylinder structure is formed in the same cylinder body. The electric-gas hybrid type piston cylinder structure has the characteristics that the feeding form is diversified, the application range is wide, and the production efficiency is high.

Description

technical field [0001] The invention relates to a piston cylinder, in particular to an electric-air hybrid piston cylinder structure. It is suitable for the control of fast switching from mold pneumatic processing to CNC processing. It belongs to the technical field of mechanical processing equipment. Background technique [0002] At present, piston cylinders are widely used in machining equipment, including electric piston cylinders and pneumatic piston cylinders. In the prior art, whether it is an electric piston cylinder or a pneumatic piston cylinder, its structure is a single structure, that is, it is all driven by electric drive or pneumatic drive, and it can only constitute one feeding mode when applied to a machine tool. For example, the Chinese Patent Announcement discloses an invention patent application titled "Drive Motor with Cylinder Mechanism for Hybrid Vehicle" and publication number "CN103840600A". The outer end of the tubular body has a flange that fits ...
