Description
Technical field
The present invention relates to silicon nitride technical field more particularly to a kind of alpha-silicon nitride powders milling apparatus.
Background technique
Silicon nitride is a kind of important structural ceramic material.It is a kind of superhard substance, itself has lubricity, and resistance to
Abrasion is atomic crystal；It is anti-oxidant when high temperature.And it can also resist cooling thermal impact, be heated to 1000 DEG C or more in air,
Quick refrigeration sharply heats again, will not fragmentation.There is so excellent characteristic just because of silicon nitride ceramics, people are usually sharp
The mechanical components such as bearing, blade of gas turbine, mechanical seal ring, permanent mold are manufactured with it.If with high temperature resistant and not
The silicon nitride ceramics to readily conduct heat manufactures the heating surfaces of engine components, diesel engine quality not only can be improved, saves fuel, and
And it can be improved the thermal efficiency.
The grinding of silicon nitride mainly realizes that the mode of underhand polish not only produces effect by way of underhand polish at present
Rate is low and grinding is uneven, wastes physical strength, and the labor intensity of personnel is larger, and it is strong that long-time hand lapping will affect employee's body
Health.
Therefore, it is very necessary for inventing a kind of alpha-silicon nitride powders milling apparatus.
Summary of the invention
For in the prior art, silicon nitride grinds existing defect, and a primary object of the present invention is to provide one kind
Alpha-silicon nitride powders milling apparatus.
In order to solve the above technical problems, the present invention provides a kind of alpha-silicon nitride powders milling apparatus, eccentric wheel, shaft, drawing
Bar, hemispherical abrasive body and cylinder；Eccentric wheel center is fixed in above shaft, pull rod one end and the non-axial location of the eccentric wheel
Hingedly, the other end and hemispherical abrasive body upper end are hinged, and hemispherical abrasive body lower end is hemisphere, and protruding into bottom is half
It is tangent with the hemisphere inner wall of the cylinder lower end in the cylinder of sphere, the pull rod and the hemispherical abrasive body articulated shaft
It is each attached in rack with the shaft.
Preferably, the hemispherical abrasive body can rotate 0-90 ° along the articulated shaft of the upper end.
Preferably, the cylinder is made of cast iron materials.
Preferably, the rod length is adjustable.
The present invention pulls hemispherical abrasive body to grind the silicon nitride of inner barrel repeatedly using eccentric wheel disc through pull rod
Mill, using the tangent grinding for realizing silicon nitride fine particle of hemispherical abrasive body and cylinder inboard wall, grinding efficiency is high, structure letter
Single, manufacturing cost is high.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is facing structure figure of the present invention.
In figure,
1- eccentric wheel, 2- shaft, 3- pull rod, 4- hemispherical abrasive body, 5- cylinder.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, and embodiments of the present invention include but is not limited to
The following example.
To achieve the goals above, The technical solution adopted by the invention is as follows:
As shown in Figure 1, the alpha-silicon nitride powders milling apparatus, including eccentric wheel, shaft, pull rod, hemispherical abrasive body and cylinder；Partially
Heart wheel center is fixed in above shaft, and pull rod one end and the non-axial location of the eccentric wheel are hinged, and the other end and hemispherical are ground
Body upper end is hinged, and hemispherical abrasive body lower end is hemisphere, and protruding into bottom is in hemispheroidal cylinder, with the cylinder
The hemisphere inner wall of lower end is tangent, and the pull rod and the hemispherical abrasive body articulated shaft and the shaft are each attached to rack
On, the hemispherical abrasive body can rotate 0-90 ° along the articulated shaft of the upper end, and the cylinder is made of cast iron materials, described
Rod length is adjustable.
The present invention pulls hemispherical abrasive body to grind the silicon nitride of inner barrel repeatedly using eccentric wheel disc through pull rod
Mill, using the tangent grinding for realizing silicon nitride fine particle of hemispherical abrasive body and cylinder inboard wall, grinding efficiency is high, structure letter
Single, manufacturing cost is high.
Using technical solutions according to the invention or those skilled in the art under the inspiration of technical solution of the present invention,
Similar technical solution is designed, and reaches above-mentioned technical effect, is to fall into protection scope of the present invention.
