Abstract
The invention relates to a spindle transmission structure of a numerical control milling and drilling machine. A spindle seat is fixedly provided with a motor seat; a spindle is rotatably arranged in the spindle seat; one end of the spindle is provided with a driven belt wheel; a spindle motor mounting plate is movably arranged on the motor seat and is fixedly provided with a spindle motor; an output shaft of the spindle motor is provided with a driving belt wheel; both the driving belt wheel and the driven belt wheel are provided with a synchronous belt; an adjusting plate is fixedly arranged on the motor seat; an adjusting bolt hole is formed in the adjusting plate; an adjusting bolt is inserted into the adjusting bolt hole; one end of the adjusting bolt is connected to the inside of the spindle motor mounting plate through threads; and the adjusting bolt positioned on the outer side of the adjusting plate is connected with an adjusting nut through threads. The spindle transmission structure is simple and has reliable performance and high transmission accuracy. The driven belt wheel is prevented from sliding downwards by the tension of the driving belt wheel, so that the service life of the synchronous belts can be prolonged.
Description
Technical field
The present invention relates to a kind of mechanism that is applied to make in the numerical control drilling-milling bed spindle drive, 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.By manually tightening screw and making alignment pin, reach the position of fixed main shaft seat; Rotate by motor rotating band movable belt pulley, be transferred to main shaft, realize the rotation of main shaft in proper order by the step band.But because the shortcoming of this mechanism is owing to have a pulling force to the center synchronously, 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 be subjected to 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 that enterprise produces.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, 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 technical scheme provided by the invention, the main shaft driving structure of described numerical control drilling-milling bed, be included in and be installed with motor cabinet on the spindle drum, in spindle drum, be rotatablely equipped with main shaft, end at main shaft has passive belt wheel, on motor cabinet, be movably installed with the spindle motor installing plate, be installed with spindle motor on the spindle motor installing plate, has driving pulley on the output shaft of spindle motor, driving pulley and passive belt wheel are provided with synchronous band, on motor cabinet, be installed with adjustable plate, in adjustable plate, offer the adjusting bolt hole, be plugged with the adjusting bolt in regulating bolt hole, 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.
Stability Analysis of Structures of the present invention, dependable performance, transmission accuracy height.The present invention 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 an overall structure schematic diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, the present invention 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, be included in hard-wired motor cabinet 8 on the spindle drum 2, in spindle drum 2, be 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, has 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 present invention 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.
Having position limiting convex ring 12 at the bottom of driving pulley 9 outer wall can prevent synchronously with 10 downslides on driving pulley 9.
