Background technique
Grinding is using coating or to be press-fitted the abrasive grain on lap tool, the phase by lap tool with workpiece under a certain pressure
The finished machined (such as machining) that movement carries out finished surface.Grinding can be used for processing various metals and non-metallic material
Material, the surface shape of processing have plane, inside and outside cylindrical surface and circular conical surface, convex, concave spherical surface, screw thread, the flank of tooth and its alloytype face.But
It is to be limited due to existing grinding technics by abrasive grain partial size, machining accuracy is typically only capable to reach IT5~IT01, and surface is thick
Rugosity can only achieve Ra0.63~0.01 micron.How to break through existing attrition process precision to be limited by abrasive grain partial size, reach
It is a technical problem to the attrition process precision of greater degree.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of high-pressure gas-liquid grinding device, to solve existing attrition process
Precision is limited by abrasive grain, and machining accuracy improves the big technical problem of difficulty.
High-pressure gas-liquid grinding device of the present invention, including horizontal table, vertical first be fixed below horizontal table
Motor, the high-pressure sealed cabin that horizontal table top is set and the workpiece erecting bed being arranged in high-pressure sealed cabin, it is described
The shaft of first motor is fixedly connected after passing through horizontal table straight up with workpiece erecting bed, is set on the high-pressure sealed cabin
It is equipped with breather cheek valve and relief valve, is additionally provided with hatch door on the side in high-pressure sealed cabin.
Further, the second motor is additionally provided at the top of the high-pressure sealed cabin, the shaft of second motor is worn downwards
Enter high-pressure sealed cabin, and is connected with the propeller or the turbine disk of driving abrasive media flowing in the shaft of the second motor.
Further, rolling center is also connected with by bracket in the high-pressure sealed cabin, the rolling center is downwards
The center of face workpiece erecting bed.
Further, breather cheek valve is provided on the inlet suction port.
Beneficial effects of the present invention:
High-pressure gas-liquid grinding device of the present invention, workpiece is placed under high pressure gas or highly pressurised liquid environment, when the first electricity
When machine drives workpiece rotation, reach grinding work-piece surface using the friction between workpiece surface and high pressure gas or highly pressurised liquid
Purpose, the medium due to playing abrasive action is gas molecule or fluid molecule, and the partial size of abrasive media substantially reduces, thus
The problem of existing grinding device grinding precision is limited by abrasive grain is breached, raising workpiece grinding precision that can be very big.
Detailed description of the invention
Fig. 1 is the schematic perspective view of embodiment mesohigh gas-liquid grinding device；
Fig. 2 is the schematic cross-sectional view of embodiment mesohigh gas-liquid grinding device；
Fig. 3 is structural schematic diagram of the Fig. 2 after rolling center is arranged.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown, the present embodiment high-pressure gas-liquid grinding device, including horizontal table 1, it is fixed on horizontal operation vertically
First motor 2 below platform is arranged in the high-pressure sealed cabin 3 on horizontal table top and is arranged in high-pressure sealed cabin
Workpiece erecting bed 4, the shaft of the first motor are fixedly connected after passing through horizontal table straight up with workpiece erecting bed, institute
It states and is provided with inlet suction port 5 and relief valve 6 on high-pressure sealed cabin；Relief valve is used for the air pressure in high-pressure sealed cabin and presses beyond setting
Releasing pressure automatically is carried out when power, guarantees equipment safety operation；Hatch door 7 is additionally provided on the side in high-pressure sealed cabin, it can by hatch door
Carry out the operation and observation grinding situation of workpiece loading and unloading.
In the present embodiment, workpiece erecting bed 4 is mounted on the bottom in high-pressure sealed cabin by bearing 8, and high-pressure sealed cabin passes through
Bolt 9 is fixed on horizontal table, and first motor is mounted on horizontal base by resilient cushion 9.
When the present embodiment mesohigh gas-liquid grinding device works, the fixture of fixed workpiece is first mounted on workpiece erecting bed
On, then workpiece is fixed on fixture, hatch door is then shut again, then gas or liquid are passed through into high-pressure sealed cabin, make workpiece
Workpiece erecting bed high speed rotation is driven under high pressure gas or highly pressurised liquid environment, then through first motor, is revolved using high speed
The friction between workpiece surface and high pressure gas or highly pressurised liquid turned achievees the purpose that grinding work-piece surface.The present embodiment high pressure
Gas-liquid grinding device, since it is to be ground using gas molecule or fluid molecule as abrasive media, abrasive media
Partial size substantially reduce, can be very big thus the problem of grinding precision for breaching existing grinding device is limited by abrasive grain
Improve workpiece grinding precision.
It is additionally provided with the second motor 10 at the top of the high-pressure sealed cabin as a further modification of the present embodiment, described second
The shaft of motor is connected with the propeller of driving abrasive media flowing down through high-pressure sealed cabin, and in the shaft of the second motor
11, propeller drives abrasive media and workpiece reverse movement, it is possible to increase the speed of related movement of abrasive media and workpiece, raising are ground
