In the present embodiment, the number of teeth of positioning gear 4 is 360, and work in-process heart digital control system is equipped with display screen.Work as drive
When dynamic motor 1 drives main shaft 2 to rotate, 2 displacement of main shaft that the motor encoder in driving motor 1 is detected passes through numerical control system
The display screen of system is shown；Gear 4 is positioned simultaneously to rotate with main shaft 2, often turns over the corresponding angle of a tooth, position sensor
5 just export a sine wave, and are converted sine wave signal by digital control system analog-digital converter, and pass through digital control system
Other devices finally detection and localization encoder shows on a display screen 2 displacement of main shaft detected, to be conveniently operated
Personnel's logarithm is compared to be accurately located main shaft 2, prevents main shaft from Wrong localization failure occur.
The beneficial effects of the utility model are：By fixed with encoder to count in existing machining center driving motor
On the basis of position, a detection and localization encoder is added again outside work in-process heart driving motor, is realized double count positioning, is led to
The data detected for crossing two encoders are compared, and operating personnel can accurately know the positioning scenarios of main shaft, carry
High setting accuracy, and can know whether encoder breaks down in real time by data comparison.
Above example is only the preferred embodiment lifted to absolutely prove the utility model, the guarantor of the utility model
It is without being limited thereto to protect range.Those skilled in the art on the basis of the utility model made by equivalent substitute or transformation,
It is within the protection scope of the utility model.The scope of protection of the utility model is subject to claims.
