Description
Technical field
The present invention relates to zirconia ceramics field, more particularly, to be a kind of cryogenic processor of zirconia ceramics.
Background technology
Zirconia ceramics hardness is high, toughness is low, brittleness is high, micro-crack easily occurs in material in process, and tool wear is fast,
Both diamond cutter is used, one can only also process cutter 5 to 7 ceramic casings.And due to the abrasion of cutter, make zirconium oxide
Ceramic manufacturing size is not in place, it is easy to zirconia ceramics chipping be made micro-crack occur.
Invention content
The purpose of the present invention is to overcome the above shortcomings and to provide reduce tool wear, monitor the one of zirconia ceramics crackle
The cryogenic processor of kind zirconia ceramics.
To achieve the above object, technical solution of the invention is：A kind of cryogenic processor of zirconia ceramics, packet
The workbench for including machine body, being arranged on machine body, further include sequentially connected acoustic emission sensor, preamplifier and
Computer, workbench are equipped with refrigeration fixture, and refrigeration fixture includes the working face for accepting workpiece, and acoustic emission sensor is set to
On working face, the lower section of working face is equipped with refrigerating plant.Refrigeration fixture can freeze to zirconia ceramics workpiece, optimize oxygen
Change the processing performance of zircon ceramic.Acoustic emission sensor can incude the generation of the fine fisssure in zirconia material process, preceding storing
The signal of acoustic emission sensor is amplified and is sent to computer by big device to be handled, to find zirconia material in time
Early stage slight crack.
Preferably, freeze fixture side be equipped with for refrigeration fixture spray cold air cold air nozzle.Accelerate refrigeration fixture
The cooling rate of interior zirconia ceramics workpiece and to after cooling zirconia ceramics workpiece keep the temperature.
Preferably, refrigerating plant is the pipeline of semiconductor refrigerating plate or the interior refrigerant for being equipped with flowing.
Preferably, acoustic emission sensor includes metal shell, piezoelectric element, high-frequency socket, lead, is equipped in metal shell
Chamber, piezoelectric element are set to the bottom of chamber, and conducting resinl is equipped between piezoelectric element and metal shell, is set at the top of piezoelectric element
It includes outer conductor and the interior inner wire for being placed on outer conductor to have silver conductive layer, high-frequency socket, and outer conductor is set on metal shell, lead
In chamber, the both ends of lead are separately connected the top of inner wire and piezoelectric element；Protective film is set to the bottom surface of metal shell,
Protective film is electrical insulating film.Acoustic emission device can receive the crackle that processing zirconium oxide process generates, and be able to detect that micro-
Small vibration finds initial failure early, reduces quality cost, reduces the waste of raw material, reduces substandard product and comes into the market
Chance, greatly promote the quality of product.
By using above-mentioned technical solution, the beneficial effects of the invention are as follows：Freezing fixture can be to zirconia ceramics work
Part freezes, and optimizes the processing performance of zirconia ceramics workpiece, and when being ground by diamond grinding head, cutter consumes more
Small, processing efficiency improves, and reduces to the loss of diamond grinding head, and machining accuracy higher reduces the chipping of workpiece
Micro-crack generates.Acoustic emission sensor can incude the generation of the fine fisssure in zirconia material process, and preamplifier is by sound
The signal of emission sensor is amplified and is sent to computer and handled, to find that the early stage of zirconia material is split in time
Trace.
