Abstract
The utility model relates to a kind of numerical control tapping machine feed mechanism, comprise ball screw, feeding motor, rotary encoder, described feeding motor is connected with main spindle box by extension bar, feeding connecting plate for electric motor, the ball screw connecting feeding motor is arranged in main spindle box inner chamber by bearing block, be connected by connecting plate between ball screw with sleeve, main shaft is arranged in sleeve by bearing, and described rotary encoder is connected with feeding motor by PLC control system.The effect that utility model is useful is: the converting rotary motion of feeding motor is upper and lower rectilinear motion by described ball screw, and main shaft is moved up and down, and makes tapping accurate.
Description
Technical field
The utility model relates to numerical control tapping machine field, especially a kind of numerical control tapping machine feed mechanism.
Background technology
Existing numerical control tapping machine feed mechanism mainly feeding motor connects gear shaft through reductor thus is with the form that moving sleeve moves up and down.Because gear clearance causes feeding motor positive and negative rotation and sleeve inconsistent up and down, thus increase tapping difficulty.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of numerical control tapping machine feed mechanism of simple and reasonable, precision high.
The utility model solves the technical scheme that its technical problem adopts: this numerical control tapping machine feed mechanism, comprise ball screw, feeding motor, rotary encoder, described feeding motor is connected with main spindle box by extension bar, feeding connecting plate for electric motor, the ball screw connecting feeding motor is arranged in main spindle box inner chamber by bearing block, be connected by connecting plate between ball screw with sleeve, main shaft is arranged in sleeve by bearing, and described rotary encoder is connected with feeding motor by PLC control system.
As preferably, described main spindle box is provided with upper and lower limited block, and described sleeve is provided with limit switch, and described limit switch is connected with PLC control system.
As preferably, directly connected by shaft coupling between described feeding motor and ball screw.
As preferably, described PLC control system adopts 4.3 cun of color touch screens.
The effect that utility model is useful is: the converting rotary motion of feeding motor is upper and lower rectilinear motion by described ball screw, and main shaft is moved up and down, and makes tapping accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals: main shaft 1, sleeve 2, connecting plate 3, ball screw 4, PLC control system 5, rotary encoder 6, feeding motor 7, feeding connecting plate for electric motor 8, shaft coupling 9, extension bar 10, main spindle box 11, bearing block 12, upper and lower limited block 13, limit switch 14.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: as Fig. 1, this numerical control tapping machine feed mechanism, comprise ball screw 4, feeding motor 7, described feeding motor 7 is connected with main spindle box 11 by extension bar 10, feeding connecting plate for electric motor 8, described ball screw 4 is arranged in main spindle box 11 inner chamber by bearing block 12, described ball screw 4 is connected by connecting plate 3 with between sleeve 2, and described main shaft 1 is arranged in sleeve 2 by bearing.
Directly connected by shaft coupling 9 between described feeding motor 7 and ball screw 4.
During work, PLC control system 5 is when receiving the signal feedback of rotary encoder 6, PLC control system 5 controls feeding motor 7 and rotates, then be the rectilinear motion up and down of main shaft by the converting rotary motion of feeding motor 7 by ball screw 4, thus reach Tapping Function on General, make tapping accurate.
Described PLC control system 5 comprises PLC, man machine operation interface and button, and wherein man machine operation interface adopts 4.3 cun of color touch screens.
Described main spindle box 11 is provided with upper and lower limited block 14, and described sleeve 2 is equipped with limit switch 13, described limit switch 13 is connected with PLC control system 5, during work when main shaft about 1 rectilinear motion exceedes the stroke of setting, limit switch 13 and upper and lower limited block 14 bump against, limit switch 13 passes to PLC control system 5 signal, and PLC control system 5 controls feeding motor 7 and stops.Prevent the damage of equipment, extend its service life.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
