Abstract

The invention relates to a clamping oil cylinder structure which comprises a cylinder body, an oil cylinder and an end cover which are connected into an oil cylinder body through screws. A second piston divides the inner space of the whole oil cylinder into a first cavity body and a second cavity body, and a first piston is placed in the first cavity body; the right end of a clamping rod is in thread connection with a second piston; a second butterfly-shaped elastic spring and a first butterfly-shaped elastic spring are respectively placed between a support base and a second spherical pressing plate and between the support base and a first spherical pressing plate; a first locking nut and a second locking nut are connected with the clamping rod through threads and form compression pretightening through the first butterfly-shaped elastic spring and the second butterfly-shaped elastic spring, and the first clamping plate and the second clamping plate are at the released working positions; and the first clamping plate is connected with the first spherical pressing plate through screws, and the second clamping plate is connected with the second spherical pressing plate through screws. The clamping oil cylinder structure can output large clamping force with the oil cylinder and the diameter of the oil cylinder limited so as to meet the requirements for clamping a rotating table during milling processing of the rotating table, and operation of a machine tool can be stable and reliable.

Description

technical field [0001] The invention relates to a clamping oil cylinder structure, which is particularly suitable for clamping a rotary table in a numerical control device, and belongs to the technical field of mechanical structures. Background technique [0002] A clamping oil cylinder structure is used in the CNC milling and turning compound machining center equipment. Since the equipment needs to complete the positioning milling process, it is necessary to configure the clamping oil cylinder to ensure the fixation of the turntable during the milling process. When the common single-piston clamping cylinder design is adopted, the piston area of ​​the single-piston clamping cylinder is limited by the installation space of the hydraulic clamping cylinder of the equipment, and cannot satisfy the clamping force of the rotary table under the common hydraulic working pressure of the equipment. need. Contents of the invention [0003] The object of the present invention is to o...
