Pneumatic clamping device

Abstract

The invention discloses a pneumatic clamping device which is composed of chuck devices (1), an upper box (2), a cylinder device (3) and a lower bottom plate (4). The number of the chuck devices (1) is 4-8, the chuck devices (1) are installed on the upper box (2), the upper box (2) is connected with the upper side of the lower bottom plate (4), the chuck devices (1) are connected with the cylinder device (3), and the cylinder device (3) is located in the upper box (2) on the upper side of the lower bottom plate (4). The pneumatic clamping device is designed into a multi-clamping-position pneumatic clamping device, and space of a worktable of a numerical control machining center is used to the largest extent to clamp more parts and achieve one-by-one machining. Clamping is achieved at 4-8 points, electric control and pneumatic control are combined, clamping and machining speed is effectively increased, and accordingly machining efficiency is improved. Work efficiency of the numerical control machining center is improved, quick replacement is achieved, part production quality is improved, and labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of structural design and application of a clamping device, and in particular provides a pneumatic clamping device. Background technique [0002] At present, the CNC machining center machine tool in the electrical connector industry adopts the manual single clamping position clamping method, which has low processing efficiency. The processing method uses a three-jaw chuck to clamp one piece at a time, the working stroke of the machine tool is not fully utilized, and the machine tool is wasted. Moreover, each time a piece is clamped, the tool needs to be changed two to three times. After a work shift, workers need to frequently clamp parts, and machine tools need frequent tool changes. These are non-cutting times, and the processing efficiency cannot be improved. In addition, the clamping method is as follows: The three-jaw chuck is manually clamped, the labor intensity of the workers is high, and the stress p...

[0002] At present, the CNC machining center machine tool in the electrical connector industry adopts the manual single-clamp clamping method, which has low processing efficiency. The processing method uses a three-jaw chuck to clamp one piece at a time. The working stroke of the machine tool is not fully utilized, and the machine tool is wasted.

Moreover, each time a piece is clamped, the tool needs to be changed two to three times. After a work shift, workers need to frequently clamp parts, and machine tools need frequent tool changes. These are non-cutting times, and the processing efficiency cannot be improved. In addition, the clamping method is as follows: The three-jaw chuck is manually clamped, the labor intensity of the workers is high, and the stress point of the parts is uneven, the clamping force cannot be accurately grasped, and the mandrel is easy to rotate, which often causes the clamping deformation of the parts, and the thin-walled parts are easy to crack. cause parts to be scrapped
