Abstract
The invention discloses a kind of sealing ring mechanical lapping face pressure adjusting means, mainly including frame, bearing, rotating shaft, pin, flexible member and cavity etc..The change of value of elastic is realized by changing the decrement of flexible member, and then adjusts sealing ring face machined flat than pressure, the scale processing of grinding elastic force is on cavity, and the pointer on pin is read, and flexible member is usually spring or bellows.When the present invention realizes sealing ring mechanical lapping, the continuously adjustable of face pressure is simple and reliable for structure.
Description
Technical field
The present invention relates to sealing ring mechanical grinding techniques field, it is adaptable to end face when mechanical seal ring mechanical lapping and polishing
Than the regulation of pressure.
Background technology
Mechanical seal be key link in one of important composition of rotation axis seal form, mechanical seal process it
One is the processing of sealing ring end face, and its requirement on machining accuracy is high, surface roughness requirements Ra≤0.1 μm, and planarity requirements are 0.6
Within μm, common machining process can only achieve Ra0.4 μm, it is therefore desirable to sealing is realized by the method for mechanical lapping
The processing of ring end face, to ensure sealing property.
When sealing ring uses mechanical lapping, end surface grinding is more larger on production efficiency and quality influence than pressure.Abrasive tip
If face is too smaller than pressing, grinding production efficiency is too low or the peaceful face degree of product roughness can not meet requirement.Conversely, abrasive tip
If face is too bigger than pressure, seal face roughness, which is also not easy to meet, to be required.Therefore, should be according to sealing ring material and grinding agent kind
Class etc. selects suitable seal face grinding ratio pressure.
At present, provide grinding ratio pressure using grinding counterweight during sealing ring mechanical lapping, i.e., it is corresponding in sealing ring upper ends
Balancing weight, although such a method, which disclosure satisfy that, is actually needed, but with certain shortcoming:Seal face grinding ratio pressure can not connect
Continuous regulation, and need the sealing ring for different size to process different grinding counterweights, produce relatively complicated.

It is above the basic structure of the present invention, the operation principle of the structure is:
When sealing ring is ground, sealing ring coordinates with adapter small end 102 to be installed, and sealing ring drives adapter 10, chamber successively
Body 9, flexible member 8 are rotated together, and cavity 9 drives rotating shaft 6 to rotate by connector 7, and frame 1 and bearing block 2 are remained stationary as.
When regulation is than pressure, rotary shaft bearing 2 moves up and down it, and the motion band dynamic bearing 4 of bearing block is moved up and down, bearing
4 and then drive rotating shaft 6 to move up and down, thus different thrusts can be obtained with the decrement of regulation elasticity element 8, realized
Face machined flat is continuously adjusted than pressure.
Based on the basic structure, the present invention can also make following optimization and limit:
Further, the side length direction of groove 91 of the invention sets elastic scale value.
Further, connector 7 of the invention is preferably pin.
Further, one end that connector 7 of the invention coordinates with groove 91 is machined with pointer, for indicating elastic force scale
Value.
Further, the inner ring of bearing 4 of the invention is compressed by being arranged on the nut 3 at the top of rotating shaft 6, the bearing
4 outer ring is compressed by the gland 5 being fixedly connected with bearing block 2.
Further, flexible member 8 of the invention can be spring or bellows.
Further, the outside of the small end 102 of adapter 10 of the present invention is additionally provided with protective case 11, can prevent switching
First 10 pairs of sealing rings produce frictionally damage.
Further, the material of protective case 11 of the invention is F4, and such a material is easy to processing, and can keep away well
Exempt from sealing ring and produce damage.
Compared with prior art, advantage is the present invention:
1st, adjusting means is pressed the invention provides a kind of seal face grinding ratio, with continuously adjustabe, easy to adjust excellent
Point.
2nd, the present invention is simple in construction, easy to use.
3rd, the present invention can be clearly showed that than pressure value.
4th, service life of the present invention is long.
