Abstract
The utility model relates to a grinding device for high precision measuring tools, which takes a cast iron plate as a carrier, and alumina ceramic blocks can be embedded into the cast iron plate so as to form a compound grinding disc. A ceramic measuring block grinding disc of utility model has the advantages of long-term and stable performance, high planeness, high productive efficiency, low material consumption, etc. The ceramic measuring blocks ground by the utility model need not surface treatment, and the measuring blocks has the advantages of uniform surface gloss, high smooth finish and high accuracy rate.
Description
The utility model relates to a kind of lapping device of high-accuracy measurer.
As everyone knows, long measure rice is defined as light in a vacuum, and the length of stroke in 1/299792458 second time interval is called one meter.Optical maser wavelength is to duplicate the natural reference of Mi Dingyi, and gauge block then is the material standard of long measure.The length of gauge block is decided to be the distance between the two horizontal survey faces, therefore, the flatness of the depth of parallelism between the gauge block working face and each working face is required very accurate, tens between the hundreds of nanometers.The material of gauge block develops into carbide alloy from traditional special steel and reaches to ceramic material, and the processing of its flatness, the depth of parallelism still adopts traditional cast iron plate to grind.The defective of tradition cast iron abrasive disk processing ceramic gauge block is as follows: 1. the case hardness of cast iron abrasive disk is more much lower than the ceramic gauge block case hardness that will add, in the process of lapping, the consume of abrasive disk surface is bigger, to abrasive disk surface duty is distorted, repair the increase of number of times and finishing time, operating efficiency is very low; 2. because the smalls of cast iron abrasive disk surface abrasion infiltrates in little pore of ceramic gauge block working face, make the ceramic gauge block working face outward appearance that processes can not meet specification requirement, hardness reduces and is inhomogeneous; 3. in order to remove the cast iron end of the abrasive disk that infiltrates in the little pore of ceramic gauge block, adopt chemical treatment method, cause ceramic gauge block working face fineness to reduce significantly, of long duration, surface peeling, thereby heavy damage the flatness and the depth of parallelism on gauge block surface, serious will cause the gauge block subscription rate.
The purpose of this utility model provides a kind of high rigidity, high strength, low-density, and diamond particle can be infiltrated, and seldom consumes the new ceramics gauge block abrasive disk of abrasive disk again.
The utility model above-mentioned purpose is achieved in that leaves a straight trough or skewed slot in the cast iron plate as the ceramic disk carrier, the coefficient of expansion according to cast iron plate and two kinds of materials of ceramic disk, accurately determine the size of ceramic body, version with 8 to 24 fan-shaped splicings, the ceramic grinding body is bumped in the cast iron plate carrier, firm by glue bond, the abrasive body of formation abrasive disk; Above-mentioned ceramic grinding body can be an alumina ceramic material.
A kind of new ceramics gauge block abrasive disk described in the utility model, it is the strong point of utilizing traditional cast iron plate on-deformable advantage steady in a long-term and aluminium oxide ceramics high rigidity, high strength, low-density (easily burning into sand) after losing efficacy, be organically integrated, maximize favourable factors and minimize unfavourable ones, be made into the ceramic grinding dish.The utlity model has following advantage:
1. this structural ceramics abrasive disk is after finishing is qualified, and long-time stability are good, the flatness height;
2. the ceramic grinding dish grinds (grinding) and renders a service height, reduces finishing number of times and each time of abrasive disk, has improved 2 times of production efficiencys, reduces fine abrasive consumption, reduces production costs;
3. grind out ceramic gauge block and need not surface treatment, gauge block lustrous surface uniformity, highly polished, gauge block accuracy class height;
4. skilled operative employee uses this ceramic grinding dish, grinds a dish gauge block, 00 grade of about 5-10% wherein, 10%, 0 grade 50% of K level.
The drawing explanation:
Fig. 1 is the structural representation of a kind of new ceramics gauge block abrasive disk described in the utility model.
Fig. 2 is the sectional structure chart of a kind of new ceramics gauge block abrasive disk described in the utility model.
Specific embodiment of the utility model is seen accompanying drawing, wherein cast iron plate (1) is a circular discoid, the center is abrasive disk capacity eccentric bearing (3), have annular shape straight trough or skewed slot on the card, in this groove of institute, stud with ceramic block (2), cast iron plate (1) is fixed together by the screw that abrasive disk is connected in the screw (4) with abrasive disk capacity eccentric bearing (3).Described ceramic block (2) adopts alumina ceramic material to make, and being fan-shaped splicing block through chamfering and after grinding by 24, Precision Machining moulding again is when cast iron plate (1) is in the heat expansion state, above-mentioned ceramic splicing block is bumped in the cast iron plate carrier, sticks with glue knot firmly.Afterwards, be ground to flatness through correct grinding and different grain size Buddha's warrior attendant sand abrasive pastes and meet specification requirement.The dimensional requirement accuracy of described ceramic splicing block is very high, and it is to carry out accurate Calculation and definite by the coefficient of expansion to cast iron plate and two kinds of materials of ceramic block.By carrying out size Selection, processing and assembling, just can make the very little gauge block ground flat in splicing gap by above-mentioned requirements.
Claims (1)
1. new ceramics gauge block abrasive disk, it is characterized in that: in cast iron plate, leave a straight trough or skewed slot as the ceramic disk carrier, the coefficient of expansion according to cast iron plate and two kinds of materials of ceramic disk, accurately determine the size of ceramic body, with the version of 8 to 24 fan-shaped splicings, the ceramic grinding body is bumped in the cast iron plate carrier, firm by glue bond, constitute the abrasive body of abrasive disk, described ceramic grinding body can be an alumina ceramic material.
