Working principle of safety device for hydraulic radial drilling machine

Hydraulic radial drilling machine is an efficient hole processing equipment, which must be manually operated during the hole processing production of parts. However, accidents may occur due to the proficiency and concentration of workers, as well as other details during operation. Therefore, the safety devices of the corresponding application radial drilling machine must play a significant role. The hydraulic radial drilling machine is equipped with a safety protection mechanism, which has the advantages of small size, simple structure, convenient disassembly and assembly, and high safety performance. It effectively overcomes the defects of existing radial drilling machines without a safety protection mechanism, such as control failure, blockage, control error, and abnormality, which will lead to motor burning or damage to related transmission components.

The working principle of the safety device is as follows: once there is an abnormality in the movement of the rocker arm drill, the bottom surface of the oil cylinder set on the rocker arm and the upper plane of the pressure head bear a certain amount of pressure in a positive direction. Once the pressure exceeds the set normal value, the pressure head compresses the liquid plastic downwards, and the liquid plastic is constrained by the cylinder body and buffer, thus pushing the pressure head to move upwards, When the upward thrust of the hydraulic plastic is greater than the pressure generated by the strong spring, the pressure head drops, and the buffer rises to release the overload pressure, leaving the entire rocker drill in an idle state;
