Abstract

The invention discloses a coaxial drilling machine for a butterfly plate check valve, belongs to drilling equipment and particularly relates to equipment capable of synchronously drilling two sides of a part. The drilling machine is characterized in that a check valve body fixing tool is arranged on the middle part of a drilling machine base with supporting frames; symmetric drilling power head assemblies are arranged on two sides of the fixing tool; the power head assemblies arranged on power head seat plates are arranged on the drilling machine base through linear guide rails; motors arranged on the tops of the power head assemblies are connected with main shafts through power head transmission devices; drilling chucks are arranged at the front ends of drilling power heads arranged on the main shafts. The coaxial drilling machine for the butterfly plate check valve has the beneficial effects of realizing synchronously processing coaxial holes in the two sides under the condition of one-time clamping, guaranteeing the coaxiality of the coaxial holes in the two sides of a valve body and avoiding the processing error caused by multi-time clamping; meanwhile, the equipment is under semi-automatic control, so that the processing efficiency is improved, and the labor intensity of a worker is alleviated.

Description

technical field [0001] The invention belongs to drilling equipment, in particular to equipment capable of simultaneously drilling both sides of a component. Background technique [0002] Check valve is a common valve product in production, which is widely used in petroleum, chemical industry, water treatment and other fields, and is the main equipment to prevent liquid backflow. Butterfly plate check valve is an important type of check valve. Because of its small size and easy installation, it is widely used in production and life. [0003] The butterfly plate check valve relies on springs to push the butterfly plate. When the liquid pressure in the pipeline is higher than the spring force, the butterfly plate is pushed away by hydraulic pressure, and the check valve opens. However, when the pressure at the water inlet end of the pipeline decreases, the valve plate closes to prevent the water flow at the water outlet end from returning. The machining accuracy of the cent...
