Abstract
A connector for numerical control lathe encoder is characterized in that the connector comprises a rubber hose with two ends fitted with the outer diameters of the main shaft of lathe encoder and headstock spline shaft and two ends of the rubber hose are arranged with fixed jaws. The utility model has rational designation and simple structure. Because the rubber hose has very ideal vibration damping performance, the utility model can avoid the harmful signal being transferred to the encoder and the encoder being damaged for the vibration of headstock spline shaft. The utility model also has the advantages of low fabrication cost, simple installation, durability and long service life.
Description
Technical field: the utility model relates to a kind of numerically controlled lathe encoder connector.
Background technology: in the prior art, the Digit Control Machine Tool encoder is connected with the spindle stock splined shaft, and dual mode is arranged usually, and a kind of is in the centre-drilling hole of splined shaft end, and the encoder main shaft is inserted, and fixes with fixed screw then.It is directly indirect that this connected mode belongs to rigidity, and the one, the unwanted signals such as vibrations of splined shaft can be passed to encoder, and pass to microcomputer in company with spindle speed signal by encoder, cause the MICROCOMPUTER PROCESSING distortion, influence machine finish; The 2nd, the vibrations of splined shaft directly involve encoder, also cause encoder to damage easily, reduce encoder service life; The 3rd, because splined shaft directly is connected with the encoder main shaft, in case the oil seal failure leakage of oil of splined shaft end, lubricating oil just can flow into encoder, causes encoder to damage.Another kind of mode is to adopt a spring, and a sleeve pipe is respectively established at the two ends of spring, is set with on encoder main shaft and splined shaft, and connects with fixing realization of fixed screw.This connected mode directly connects existing above-mentioned defective though overcome above-mentioned rigidity, and its interface unit manufacturing cost height is installed also more bothersomely, and spring easily lost efficacy, damage easily, service life weak point.
Technology contents: the purpose of this utility model provides a kind of novel Digit Control Machine Tool encoder connector, in order to overcome the existing above-mentioned defective of prior art connected mode.The utility model is realized that by following mode it has a rubber tube, and the two ends internal diameter of this rubber tube is corresponding with the external diameter of lathe encoder main shaft and headstock splined shaft axle head respectively, and two ends all are provided with fixing card.During use, with rubber tube terminal be set with encoder main shaft and headstock splined shaft on, connect with fixing promptly realization of the fixedly card at two ends chucking.
The utility model is reasonable in design, simple in structure, because rubber tube has very desirable damping performance, not only can avoid unwanted signals such as headstock splined shaft vibrations to the encoder transmission, can also avoid the splined shaft vibrations to cause encoder to damage, even if splined shaft oil seal failure, lubricating oil can not flow into encoder yet and cause its damage; And low cost of manufacture is installed simply, and is not fragile, long service life.
Description of drawings: accompanying drawing is a novel embodiment schematic diagram of this use
The specific embodiment: accompanying drawing has provided a novel embodiment of this use, with reference to the accompanying drawings, 2 is rubber tubes among the figure, the main shaft external diameter of left end internal diameter and encoder 4 is corresponding, be set on the main shaft of encoder 4, the axle head external diameter of right-hand member internal diameter and headstock splined shaft 1 is corresponding, is set in the axle head of splined shaft 1, and two ends are fixing with fixing card 3 chuckings.
