Large vertical lathe turntable clamping device

Abstract

The invention relates to a clamping device of a large-scale vertical lathe rotating table, belonging to the technical field of machine tool. The clamping device comprises a mechanism body, an upper-and-lower rotating axis, an upper-and-lower scissor body, an upper-and-lower piston body, an upper-and-lower ball surface gasket component, a spring, an oil cylinder, and the like. When the rotating table clamps, the hydraulic pressure oil with certain pressure is pumped from a hydraulic pressure oil inlet; the tail end of the upper-and-lower scissor body is lifted through the upper-and-lower piston body and the upper-and-lower ball surface gasket component so that the head part of the scissor body clamps the rotating part of the rotating table. The clamping mechanism is convenient to produce; the force can be amplified so that the clamping is firmer and more stable; and the clamping mechanism is arranged outside the machine tool, thereby being convenient to assemble, adjust and maintain.

Description

technical field [0001] The invention relates to the field of turntables for machine tools, in particular to a clamping device for a large vertical lathe turntable. Background technique [0002] As we all know, at present, the clamping of large-scale vertical car turntables is generally completed by built-in oil cylinders and tightened by T-shaped ring grooves. Due to the large size of the turntable surface of the large vertical lathe, it is very difficult to process the annular T-shaped groove, and once the processing size deviates, the T-shaped top of the oil cylinder will easily rub against the T-shaped groove when the turntable is running, and in serious cases, it will cause serious damage. ACCIDENT. In addition, the clamping device is inside the turntable, so it is difficult to install and debug. Once a fault occurs, the table top must be removed for maintenance, which brings great inconvenience. Contents of the invention [0003] In order to overcome the deficiencie...

Due to the large size of the turntable surface of the large vertical lathe, it is very difficult to process the annular T-shaped groove, and once the processing size deviates, the T-shaped top of the oil cylinder will easily rub against the T-shaped groove when the turntable is running, and in serious cases, it will cause serious damage. ACCIDENT

In addition, the clamping device is inside the turntable, so it is difficult to install and debug. Once a fault occurs, the table must be removed for maintenance, which brings great inconvenience
