Abstract
The utility model relates to a main axle transmission structure of a digital control milling and drilling machine. A motor seat is fixed and mounted on a main axle seat, a main axle is rotatably mounted in the main axle seat, one end of the main axle is provided with a driven belt wheel, a main axle motor mounting plate is movably mounted on the motor seat, a main axle motor is fixed and mounted on the main axle motor mounting plate, an output axle of the main axle motor is provided with a driving belt wheel and the driving belt wheel and the driven belt wheel are provided with synchronous belts, an adjustment plate is fixed and mounted on the motor seat, an adjustment bolt hole is opened in the adjustment plate, an adjustment bolt is inserted into the adjustment bolt hole, one end of the adjustment bolt is screwed into the main axle motor mounting plate, the adjustment bolt at the outer side of the adjustment plate is screwed with an adjustment nut. The main axle transmission structure has features of stable structure, reliable performance and high transmission precision. The tension of the driving belt wheel is used for preventing the driven belt wheel from downwards sliding, so as to increase the service life of the synchronous belt.
Description
Technical field
The utility model relates to a kind of mechanism that is applied to make in the numerical control drilling-milling bed spindle, specifically is a kind of main shaft driving structure of numerical control drilling-milling bed.
Background technology
In the technology that oneself has, main shaft driving structure is by spindle drum, main shaft, motor, motor cabinet, belt wheel and is with synchronously and forms.Through manually tightening screw and making alignment pin, reach the position of fixed main shaft seat; Rotate through motor rotating band movable belt pulley, be transferred to main shaft, realize the rotation of main shaft in proper order through the step band.But, the shortcoming of this mechanism has a pulling force synchronously to the center because being; The trend that causes the oriented center of motor cabinet to be leaned on; When the center of main shaft and motor during less than band centre-to-centre spacing synchronously, the band phenomenon that will occur beating causes the inaccurate of main shaft rotation precision synchronously.Owing to receive the influence of gravity, belt wheel has the trend fallen downwards, causes that band is not in same horizontal plane synchronously, and the phenomenon of fracture can take place last band synchronously.These all do not meet the requirement of enterprise production.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and the main shaft driving structure of a kind of Stability Analysis of Structures, dependable performance, numerical control drilling-milling bed that transmission accuracy is high is provided.
According to the technical scheme that the utility model provides, the main shaft driving structure of said numerical control drilling-milling bed is included in and is installed with motor cabinet on the spindle drum; In spindle drum, be rotatablely equipped with main shaft, have passive belt wheel, on motor cabinet, be movably installed with the spindle motor installing plate in an end of main shaft; Be installed with spindle motor on the spindle motor installing plate; Have driving pulley on the output shaft of spindle motor, driving pulley and passive belt wheel are provided with synchronous band, on motor cabinet, are installed with adjustable plate; In adjustable plate, offer the adjusting bolt hole; In regulating bolt hole, be plugged with the adjusting bolt, described adjusting bolt one end is screwed onto in the spindle motor installing plate, is positioned on the adjusting bolt in the adjustable plate outside to be bolted with adjusting nut.
Outer wall has position limiting convex ring in the bottom of driving pulley.
The utility model Stability Analysis of Structures, dependable performance, transmission accuracy is high.The utility model utilizes the tensile force of driving pulley to prevent that passive belt wheel is sliding downwards, the service life that can improve synchronous band.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure, the utility model mainly by main shaft 1, spindle drum 2, spindle motor 3, spindle motor installing plate 4, adjustable plate 5, regulate bolt 6, adjusting nut 7, motor cabinet 8, driving pulley 9, be with 10 synchronously, parts such as passive belt wheel 11 and position limiting convex ring 12 constitute.
The main shaft driving structure of this numerical control drilling-milling bed is included in hard-wired motor cabinet 8 on the spindle drum 2, in spindle drum 2, is rotatablely equipped with main shaft 1; Has passive belt wheel 11 in an end of main shaft 1; On motor cabinet 8, be movably installed with spindle motor installing plate 4, be installed with spindle motor 3 on the spindle motor installing plate 4, have driving pulley 9 on the output shaft of spindle motor 3; Driving pulley 9 is provided with passive belt wheel 11 and is with 10 synchronously; On motor cabinet 8, be installed with adjustable plate 5, in adjustable plate 5, offer the adjusting bolt hole, in regulating bolt hole, be plugged with and regulate bolt 6; Described adjusting bolt 6 one ends are screwed onto in the spindle motor installing plate 4, are positioned on the adjusting bolt 6 in adjustable plate 5 outsides to be bolted with adjusting nut 7.
Outer wall has position limiting convex ring 12 in the bottom of driving pulley 9.
The course of work of the utility model and operation principle:
After being installed to spindle motor 3 on the spindle motor installing plate 4, according to 10 tightness rotation adjusting nut 7 spindle motor 3 being adjusted to suitable position synchronously, with adjusting nut 7 again fit adjustment bolt 6 fix the position of spindle motor 3.Utilize the tensile force of driving pulley 9 to prevent that passive belt wheel 11 to downslide, preventing to be with 10 to tear synchronously, improve synchronously service life with 10.
Outer wall has position limiting convex ring 12 and can prevent synchronously with 10 downslides on driving pulley 9 in the bottom of driving pulley 9.
