Description
Technical field
The present invention relates to a kind of cutter path measuring instrument of full porcelain artificial tooth grinding system.
Background technology
Defect of teeth is the common disease of the mankind, in addition to defect of teeth, and deformity teeth is also the problem of can not be ignored, with
The improvement of living condition, attention of the people to dental health strengthens all the more, higher requirement is there has also been to beautiful teeth, artificial tooth is repaiied
It is that can solve the unique method of these problems at present again, at present, it is still the typical oral restoration of domestic doctor to make artificial tooth by hand
Method, typically casts metal restoration, it is considered to attractive in appearance, the porcelain on metal artificial tooth, finally obtains porcelain artificial tooth, porcelain artificial tooth system
It is all manual operations to make process, and tedious process efficiency is low, precision is not high, the cycle is long, in addition, baking-ceramic tooth masticatory function is poor, it is impossible to
Hard food is eaten, easily abrasion, once top layer porcelain collapses porcelain, metal crown bottom can be exposed, influenceed attractive in appearance.With the hair of material technology
Exhibition, the series of advantages of bioceramic is developed in oral cavity restoration field, and no matter pure ceramic material artificial tooth is in performance, biofacies
All be far superior to metal alloy compositions All-ceramic restorations in capacitive, service life and visual appearance is considered as in dentures repai field
It is following main development direction, still, All-ceramic restoration can only be at present, existing by means of the automatic machine-shaping of CAD/CAM technologies
Dentures repai CAD/CAM system bioceramic block grinding-shaping is directed to using the motor drive diamond car that is used as power.
But existing full porcelain Dental CAD/CAM system makes full porcelain artificial tooth and must set up to be made by professional software first
The CAD model of the tooth of work, according to the CAD model of artificial tooth curved surface, according to the cutter path of planning, passes through cutter-contact point and cutter shape
Shape carries out mathematical modeling, and the cutter spacing point data of the grinding knife tool of Digit Control Machine Tool when calculating grinding finally utilizes specialty
Digit Control Machine Tool grinding on full porcelain block, produces full porcelain tooth tooth,.
Existing full porcelain artificial tooth manufacturing system is primarily present two shortcomings：
1：The CAD model of denture prosthesis is set up, it is necessary to which the special dentures repai design of expensive measuring apparatus and exploitation is soft
Part, may also need to the tooth database of various forms, and technical sophistication is with high costs, for most of general patients of China
Economically it is difficult to bear.
2：Denture prosthesis curved surface belongs to typical Engrave surface, but the shape of artificial tooth grinding knife tool (diamond card grinding)
It is widely different with traditional ball-type cutter and cylindrical type cutter, belong to circle at the top of bevel tool, cutter blunt, it is difficult to accurate to calculate mill
The cutter spacing locus of points of cutter when cutting processing, this will cause all-ceramic prosthesis to make precision reduction, or even repairing failure.
In view of above-mentioned defect, the design people is actively subject to research and innovation, to found a kind of full porcelain of new structure
The cutter path measuring instrument of artificial tooth grinding system, makes it with more the value in industry.

Limited block 6 is fixed in fixed seat 7 by mobile bar 8.
Principle used in above-mentioned cutter path measuring instrument 100 is as follows：Because the tooth defect of patient is, it is necessary to the tooth of defect
Tooth is repaired, and goes out denture with low cost using existing traditional tooth impression-taking fabrication techniques by Dental Technician first
200, the shape of denture 200 complies fully with form accuracy requirement, and with relatively good hardness.Denture 200 is consolidated
It is scheduled in the denture mounting seat 232 of above-mentioned measuring instrument, using cutter 5 as measurement contact probe, during according to grinding
The path planning of cutter 5, cutter 5 completely slides one time on denture 200, while record the position data on the summit of cutter 5,
Cutting tool path data during grinding have just been obtained, can just have been controlled to be ground the cutter path of CAM system with this data,
The denture prosthesis of the completely the same full porcelain material of shape is ground on full porcelain blank block.
The specific measuring method of cutter path measuring instrument 100 is as follows：On the artificial tooth cutter path measuring instrument invented, adopt
Along Z-direction it is divided into a number of number of plies with layering mensuration, that is, by denture 200.The each layer of spacing using fixation,
So each layer of Z-direction range data can be directly obtained；Only each layer of X, Y-direction data, which need to be measured, can obtain the summit of cutter 5
Specific spatial value.When X, Y-direction DATA REASONING, denture 200 is fixed, and operator holds handle 43, pushes away forward
Slide bar 42 on fixed handle 43 touches limited block 6 with cutter 5, then makes cutter 5 along the surface of denture 200 in water manually
Square to sliding one time, because cutter 5 and denture 200 are constantly in contact condition, connect in cutter 5 with denture 200
Touch in sliding process, X to displacement transducer 33 and Y-direction displacement transducer 41 can recorded in real time the X on the summit of cutter 5 to and Y
To position data, this layer of artificial tooth grinding knife tool track data has thus been obtained；Measure next layer data, the rotational band of motor 21
Dynamic ball-screw 22 is rotated, and upright slide block 231 is risen a constant spacing value, is driven and faced by denture mounting seat 232
When artificial tooth 200 realize Z-direction and rise one layer of distance, then repeatedly X, Y-direction DATA REASONING, so circulation, until measure temporarily
As soon as the bottom layer data of artificial tooth 200, has obtained complete artificial tooth grinding knife tool track data.
In summary, above-mentioned cutter path measuring instrument 100 passes through Z axis displacement mechanism 2, X-axis displacement mechanism 3 and Y-axis displacement
Mechanism 4, realization only needs to imitate type manually on denture, simulates grinding motion, automatically record generation cutting tool path, no
Limited by the shape of cutter 5, the CAD without artificial tooth is modeled, it is to avoid pass through cutter when complicated algorithm calculates processing and transport
Dynamic rail mark, reduces the cost that full porcelain artificial tooth makes, it is adaptable to variously-shaped cutter 5, and can overcome disadvantages mentioned above, is surveyed
The cutting tool path of amount, can be applied directly in artificial tooth Processing CAM system.In addition, when cutting tool path is measured, cutter
Whether 5 be in the judgement of contact condition as gauge head and denture 200, it is not necessary to special feeler, only with operation
The power on hand of person is perceived.
Described above is only the preferred embodiment of the present invention, is not intended to limit the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is some improvement and
Modification, these improvement and modification also should be regarded as protection scope of the present invention.
