A fast pneumatic clamping fixture for precision cnc machining

Abstract

The invention discloses a precision CNC machining rapid pneumatic clamping fixture, comprising a control body, a rectangular receiving groove is arranged on the control body, a rectangular protective plate is arranged in the rectangular receiving groove, and the control body is located at a position on the control body. The rear side of the rectangular storage slot is provided with a rear support, the control body is provided with a middle worktable at the inner side of the rectangular storage slot, the middle worktable is provided with a lower splint, and the rear support is provided with a cylinder A pneumatic shaft is arranged in the cylinder, and an upper mounting plate is arranged below the pneumatic shaft. The invention relates to a precision CNC machining fast pneumatic clamping fixture, which belongs to the field of fixtures, and can protect the workpiece by providing a rectangular protective plate and other structures to avoid projections during extrusion and damage to workers or equipment. In addition, the rectangular protective plate is easy to disassemble, and the installation is more stable through the provided wedge-shaped block structure to avoid loosening.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a fast pneumatic clamping fixture for precision CNC machining. Background technique [0002] Generally, CNC machining usually refers to computer digital control precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. The main job is to compile machining programs, that is, to convert the original manual work into computer programming. Pneumatic is often used in CNC machining There are various types of pneumatic clamping fixtures. Some pneumatic clamping fixtures mainly use the cylinder structure to drive the upper upper splint to move down, and squeeze and install the workpiece on the lower splint on the worktable, etc. However, in actual use, due to the existence of defective products, sometimes the extruded workpieces may easily cause these workpieces to project sideways, which may easily hurt the surrounding workers and ...

Problems solved by technology

[0002] General CNC processing usually refers to computer digital control precision machining, CNC processing lathes, CNC processing milling machines, CNC processing boring and milling machines, etc. The main work is to compile processing programs, that is, to convert the original manual work into computer programming. Pneumatic power is often used in CNC processing. There are many kinds of clamping fixtures through pneumatic clamping fixtures. Some pneumatic clamping fixtures mainly drive the upper upper splint to move down through the cylinder structure, and squeeze and install the workpiece on the lower splint on the workbench, etc. Work, but in actual use, due to the existence of defective products, sometimes the extruded workpieces are likely to cause these workpieces to shoot sideways, which is easy to hurt the surrounding workers and other mechanical equipment nearby, and many lower splints pass through the slider For installation, in a long time, it is easy to loosen, which will cause displacement during extrusion and affect the processing effect
