Description
Technical field
The present invention relates to a kind of temperature measuring equipment, especially a kind of when being used for flat surface grinding, the grinding area temperature measuring equipment.
Background technology
In the accurate grinding process, the grinding area temperature has very big influence to the surface quality of part to be processed and the cutting ability of emery wheel abrasive particle.When the grinding area temperature is higher, the metallographic structure of part top layer is changed, grinding burn appears.The transient temperature that grinding area is higher in grinding and cooling procedure, forms thermal stress, makes by mill part top layer and produces bigger residual stress, even the surface is cracked.For avoiding above-mentioned phenomenon to take place, the flat surface grinding process relies on operator's experience to choose working process parameter to carry out grinding, be difficult to reach optimum efficiency mostly at present.Therefore, the grinding area temperature during the measurement plane grinding how effectively is to optimizing grinding process parameters and significant to improving workpiece grinding quality and grinding efficiency.
Summary of the invention
The present invention is the grinding area temperature measuring equipment that a kind of flat surface grinding will be provided; Grinding area temperature when being used to test the surface grinding machine grinding work piece; Optimize the flat surface grinding technological parameter and improve grinding efficient, avoid workpiece to produce phenomenons such as grinding burn and big residual stress.
For realizing above-mentioned purpose, technical scheme of the present invention is; A kind of grinding area temperature measuring equipment of flat surface grinding; Comprise constantan sheet, mica sheet; Capture card; Computer; Be characterized in: constantan sheet and mica sheet are installed in the groove of grinding work piece side, and grinding work piece is connected computer with lead
through capture card through lead
respectively with the constantan sheet.
Be connected through shielded cable between capture card and the computer.Place mica-sheet insulation between grinding work piece and the constantan sheet.
The invention has the beneficial effects as follows;
The utility model adopts thermocouple principle; Conductor two ends by two kinds of heterogeneities are bonded into into the loop; When two abutment thermocouple temperature not simultaneously, will in the loop, produce electromotive force, just can demonstrate the pairing temperature value of electromotive force that thermocouple produces through corresponding instrument.The electromotive force of thermocouple will and increase along with the rising of measuring junction temperature, and its size is only relevant with the two ends temperature with thermocouple material, and will be irrelevant with length, the diameter of electrode.
The temperature of grinding area when the present invention can test the surface grinding machine grinding work piece is optimized the flat surface grinding technological parameter, and is significant to improving workpiece grinding surface quality and grinding efficiency.

5 be bonding conductor material grinding work piece 1 and thermocouple material constantan sheet 2 respectively, uses mica sheet 3 insulation between grinding work piece 1 and the constantan sheet 2; Through glue special two parts grinding work piece 1 that separates is bonded together.Size of ground workpiece size: length L=60mm, height H=50mm and width B=60mm, constantan chip size size: thickness is 20um, highly is 0.38mm for 50mm and width, the mica sheet size: thickness is 5um, highly is that 50mm and width are 0.5mm.
As shown in Figure 2; Before grinding; Be placed on the platen 6 measuring transducer and clamping earlier; Then lead
4 and lead
5 are inserted the capture card 7 that has cold junction compensation (CJC) function; Be connected with computer 9 through shielded cable 8 again, after debugging, guarantee the entire measuring device operate as normal.
Start lathe, it is V that emery wheel 10 rotating speeds are set
s, workbench 6 speed are V
wWith grinding depth be a
pCarry out grinding experiment processing, can be through the protected type capture card 7 and the shielded cable 8 that have cold junction compensation (CJC) function at the grinding area temperature value that computer 9 shows and record is tested.Shown in figure (3), temperature maximum and the measuring point temperature that can measure grinding area be change curve in time.
Each relative workpiece size of grinding allowance is less in the experiment, measures so this sensor can repeatedly use to measure and be applied to the Different Plane grinding machine; This measurement mechanism has that volume is little, characteristics such as be easy to carry.
