Background technique
Vacuum pump, which refers to, to be obtained using machinery, physics, chemically or physically chemical method to being evacuated by pumping container
The device or equipment of vacuum.For popular, vacuum pump is to improve, generate and maintain true in a certain enclosure space with various methods
Empty device.With the development that vacuum is applied, the type of vacuum pump has been developed that many kinds, pumping speed are raised to from zero point per second is several
Hundreds of thousands per second, millions of liters.Common vacuum pump include dry screw vacuum pump, water ring pump, reciprocating pump, slide valve pump, sliding vane rotary pump,
Lobe pump and diffusion pump etc., these pumps are essential main force's pumps during Chinese national economy every profession and trade application vacuum technology
Kind.
Vacuum pump primary structure includes that cylinder body is also known as the pump housing, pump case and setting in intracorporal two rotors of cylinder.It is true with screw rod
For sky pump comprising intracavity section is in the cylinder body such as Chinese patent [application number: disclosed in 201710045789.6] of 8 fonts
Pump case pump chamber structure, the inner cavity of cylinder body are equipped with a pair of of screw rod.When work, above-mentioned a pair of screw rod makees synchronous high-speed in inner chamber of cylinder block
The air-breathing generated and scavenging action are reversely rotated to realize pumping.In the actual screws vacuum pump course of work, inner chamber of cylinder block
Surface processing finish can impact above-mentioned air-breathing and exhaust, to influence the working performance of vacuum pump.That is, cylinder
The quality of the inner cavity finishing of body is extremely important.
In the prior art, then the general casting and forming of cylinder body carries out roughing to inner cavity by lathe, completes roughing
Afterwards, inner cavity generally passes through boring machine and is finished.Existing boring machine is usually made of rack, boring axis, boring cutter, and workpiece is solid by fixture
It is fixed to be then feed motion by the movement of boring axis or workpiece, original hole on workpiece is completed with this and is refined on the rack,
To obtain high-precision circularity, cylindricity and surface smoothness.So, long inner chamber of cylinder block of the existing boring machine in processing vacuum pump
When, since the inner cavity of long cylinder body is made of the cylindrical hole that two parts overlap, existing boring machine needs first in processing to wherein
One cylindrical hole is processed, and then changes the location of workpiece, then process to another cylindrical hole；From above-mentioned process point
Analysis is it is found that since the inner wall of above-mentioned two cylindrical hole is separately separately machined, it is clear that the consistency of the two Boring preciseness can not protect
Card, results in the machining accuracy of entire inner cavity boring not can guarantee in this way, and by location of workpiece change and fixture clamp precision
It influences, especially for the processing of long cylinder body, it is big to be easy to appear former and later two machining accuracy differences, not can guarantee two cylindrical holes
And the relative position tolerance of two cylindrical holes and end face, the situation for causing overall processing precision bad occur；Meanwhile it is above-mentioned separated
Processing is unfavorable for saving process time, and cumbersome, and processing efficiency is bad.
