Description

A compressor casing drilling device

Technical Field

The utility model relates to the technical field of compressor processing, in particular to a compressor shell drilling device.

Background Art

An air compressor is a device used to compress gas. It is generally the main body of an air source device. It is a device that converts the mechanical energy of a prime mover into gas pressure energy. It is a device that generates air pressure for compressed air. An air compressor is similar in structure to a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. In the process of producing the compressor, it is necessary to drill holes in its casing and drill multiple holes.

After searching, the utility model with announcement number CN219925246U discloses a drilling device for shell processing, including a base and a fixed frame, and a drilling mechanism is arranged at the lower part of the fixed frame. The utility model drives the screw to rotate by turning on the third motor, so that the threaded sleeve drives the movable plate and the rotary cylinder to move, and the rubber layer on the surface of the rotary cylinder is attached to the surface of the inner wall of the compressor shell, so as to clamp, fix and limit the compressor shell from the inside. At the same time, the rotary cylinder is driven to rotate by turning on the second motor, and the rotary cylinder can drive the compressor shell to rotate to change the position of the compressor shell. Moreover, the components used for clamping, such as the rotating drum, rubber layer, and movable plate, will not rotate with the compressor shell, so as to avoid the clamping components from obstructing the drilling, and the use is more convenient.

The device also has the following disadvantages during use: when in use, the screw is used to drive the rotating drum to expand outward to clamp the outer shell. Due to the high height of the rotating drum, the outer shell needs to be lifted and put on the three rotating drums during clamping, which makes it very laborious to clamp. In addition, the drill bit is driven to move by two sets of hydraulic cylinders, which increases the manufacturing cost. Therefore, it is very necessary to propose a compressor casing drilling device.
