Abstract

The invention relates to a pneumatic cutting assembly with a one-way valve stop function. The pneumatic cutting assembly comprises a control unit, a braking and power unit and an execution unit, the control unit is connected with the braking and power unit through a first threaded connecting piece, a working chamber in the braking and power unit is connected with a shell, a blade type pneumatic motor is arranged in the shell, the two ends of a motor shaft are supported in the shell through motor bearings, a first end of the motor shaft is provided with a large bevel gear, the large bevel gear is in meshing transmission with a small bevel gear in the execution unit, a spring seat and a friction disc are arranged at a second end of the motor shaft, the friction disc is in sliding connection with the motor shaft through a friction disc positioning key, and a spring is arranged between the spring seat and the friction disc. A one-way valve principle is utilized, the friction disc and a second threaded connecting piece are separated or attached, and thus air-loss braking of a pneumatic cutting machine can be achieved, the use safety of the pneumatic cutting machine is improved, and the pneumatic cutting assembly has the advantages of being compact in structure, easy to operate, reliable in effect and the like.

Description

technical field [0001] The invention relates to the technical field of pneumatic cutting machines, in particular to a pneumatic cutting assembly with a one-way valve stop. Background technique [0002] Pneumatic cutting machines are very common in factories and are mostly used for cutting metal and non-metal materials. Existing pneumatic cutting machines do not have a braking mechanism, and when the ventilation is stopped, the cutting blades will still rotate for a period of time due to inertia. And because the edges of cutting discs are mostly composed of diamond particles, which are very sharp, in the case of negligence, work-related accidents often occur, and there is a great potential safety hazard. To solve this problem, the present invention adds a braking mechanism between the control mechanism and the power mechanism of the pneumatic cutting machine, so that the cutting machine can work normally when the switch is pressed, and brake in time when the switch is releas...
