A continuous drilling device for safety valve

Abstract

The invention provides a device for continuously drilling in a safety valve. The device comprises a base, a mounting frame, a first driving mechanism, a drilling mechanism and a clamping mechanism, wherein the first driving mechanism is connected with a main shaft to drive the main shaft to rotate; the drilling mechanism comprises a rotating disc, a plurality of drilling rods, and a plurality of second driving mechanisms; the rotating disc is movably mounted on the main shaft and can rotate along with the rotation of the main shaft; the rotating disc moves on the main shaft vertically; the second driving mechanisms are mounted on the rotating disc and are circumferentially distributed by using the center of the rotating disc as the center; the number of the drilling rods is consistent with that of the second driving mechanisms, and each of the drilling rods is connected with one corresponding second driving mechanism; the clamping mechanism comprises a plurality of supporting discs which are separately mounted on the base, and the supporting discs are circumferentially distributed by using the main shaft as the center; and a plurality of first clamping assemblies for clamping workpieces to be processed are arranged on each supporting disc. According to the device disclosed by the invention, continuous drilling processing of the safety valve is realized, the working efficiency is high and the processing precision is high.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a continuous drilling device for safety valves. Background technique [0002] The safety valve is a valve for safety protection. Its opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises and exceeds the specified value, it will automatically open. The medium pressure in the pipeline or equipment exceeds the specified value. Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines, to control the pressure not to exceed the specified value, and play an important role in protecting personal safety and equipment operation. During the processing of the safety valve, the valve core needs to be drilled. The existing technology usually adopts a single drill bit for processing. It is not a big problem for the material to be processed that requires ...
