Description

A casing drilling device for compressor processing

technical field

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

Background technique

The compressor is a driven fluid machine that lifts low-pressure gas into high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, thereby realizing compression → condensation (heat release ) → Expansion → Evaporation (endothermic) refrigeration cycle. In the process of producing the compressor, the casing needs to be drilled, and the casing of the compressor is mostly circular, so the casing needs to be rotated during the drilling process.

After searching, for example, a Chinese patent document discloses a motor casing drilling device for motor processing [application number: CN202121305395.8; publication number: CN215786850U]. When the motor case drilling device used for motor processing is working, the motor case is first placed in the middle above the turntable, the first cylinder is activated, the first push rod can push the limit clamp to move in the left and right direction, and the two Cooperate with the limit clip to fix the motor casing, start the geared motor, the output shaft of the geared motor can drive the turntable to rotate, adjust the motor casing to a suitable position, start the third cylinder, and the third push rod can drive the lifting plate and The punching mechanism moves in the vertical direction until the required punching point of the motor casing is located on the left side of the drill bit, the second cylinder is activated, and the second push rod can push the pressure plate down until the pressure plate is close to the motor casing. Start the punching motor, then the output shaft of the punching motor can drive the drill bit to rotate, start the fourth cylinder, and the fourth push rod can drive the slide block, the punching motor and the drill bit to move to the left, thereby carrying out the drilling operation.

The above-mentioned device can punch holes in the circular motor casing, and is also suitable for the circular compressor casing. In the process of clamping the casing, the above-mentioned device only uses the cylinder to drive the limit clamp on the outside of the casing. Clamping and fixing, the outside of the casing is unilaterally stressed. At this time, the inside of the casing lacks support. Once the pressure of the cylinder is too large, it is easy to cause deformation of the casing, and the turntable of the above-mentioned device is in the process of rotation, although it can change the machine. The orientation of the casing is convenient for the drill to drill holes in different positions of the casing. However, during the rotation, since the first cylinder is fixed on the turntable, the clamping of the first cylinder, the first push rod and the limit clamp The components follow the rotation of the turntable and the casing, which will inevitably cause the parts of the casing surface covered by the clamping parts to be unable to be punched. After the casing needs to be unfixed, manually rotate the casing to keep these covered parts away from the clamping parts. , and then the casing is fixed, so that the drill bit can punch holes in the parts that have just been blocked by the clamping parts, and the whole process is very troublesome.
