Gas distribution group cover of pneumatic high pressure oil injector

Abstract

The invention belongs to the technical field of butter machines, and in particular relates to a gas distribution group cover of a pneumatic high pressure oil injector. The middle part of a gas distribution group cover main body is provided with an installation part, one side of the gas distribution group cover main body is provided with a gas outlet joint and a silencer installation joint side by side, and the other side of the gas distribution group cover main body is provided with a cylinder; a cylindrical surface of the cylinder is provided with three circles of annular grooves, and a cylindrical groove is formed in the middle on the cylindrical surface; and three strip holes are axially formed in the groove, the strip hole in the middle is communicated with a central hole of the silencer installation joint, the strip hole on one side is communicated with a central hole of the gas outlet joint, and the strip hole on the other side is communicated with a groove radially formed on the middle annular groove on the cylindrical surface. The invention has the advantages that: the gas distribution group cover main body has an integrated structure and high work efficiency and is convenient to disassemble; a silencer arranged at the silencer installation joint of the gas distribution group cover main body is convenient to assemble and disassemble, so that the oil injector is low in noise; the internal gas circuit of the oil injector is short and simple; and the cover is suitable to be used as gas distribution group covers of various pneumatic high pressure oil injectors.

Description

Technical field [0001] The invention belongs to the technical field of butter machines, and particularly refers to a gas assembly cover of a pneumatic high-pressure oil injector. Background technique [0002] At present, most of the known butter machines use the reciprocating motion of pneumatic components to drive the lifting mechanism to increase the oil pressure, and use the oil gun to inject oil into the parts that need to be oiled. The reversing valve mechanism in the oiler is easy to wear, but the existing Most of the gas distribution mechanism and the shell of the pneumatic high-pressure oil injector are an integrated structure. In this way, when the parts in the gas distribution mechanism are faulty or need to be overhauled, the pneumatic high-pressure oil injector must be completely disassembled. The point is: First, the overall disassembly and assembly will cause unnecessary damage and damage to other accessories; second, it will cause the operator to be strong and inco...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the known butter machines use the reciprocating motion of pneumatic components to drive the lifting mechanism to increase the oil pressure, and oil the parts that need to be oiled through the oil gun. The reversing air distribution mechanism in the oiler is easy to wear, but the existing Most of the air distribution mechanism and the shell of the pneumatic high-pressure oiler are an integral structure. In this way, when the accessories in the air distribution mechanism are faulty or need to be overhauled, the pneumatic high-pressure oiler must be completely disassembled. The advantages are: first, the overall disassembly and assembly will cause unnecessary damage and damage to other accessories; second, it will cause high strength for the operator and inconvenient maintenance; third, it will take a long time for maintenance
