Description
Technical field
It the utility model is related to CNC milling machine apparatus field, more particularly to a kind of CNC milling machine main shaft gearshift.
Background technology
CNC milling machine main shaft can typically set gearshift, and the different gear of main shaft, moment of torsion is different, and rotating speed is different.Main shaft
Set gearshift to be adapted to the cutting of different workpieces to require the moment of torsion of main shaft and the different of rotating speed.Existing large-sized numerical control machine
Bed typically uses self shifter, and complicated, production cost is too high, is not appropriate for for some small-sized Digit Control Machine Tool uses.
Utility model content
The problem of for shortcomings and deficiencies in the prior art, the utility model proposes a kind of CNC milling machine main shaft gearshift machine
Structure, can be with elastic timing belt, so as to adjust the difference that timing belt is located at synchronous pulley by setting long lumbar hole on motor mounting plate
On step surface, the high, low speed gearshift of main shaft is realized.
Technical scheme is used by the utility model solves its technical problem：
A kind of CNC milling machine main shaft gearshift, including main spindle box, support base, motor, installing plate, main shaft, main shaft are synchronous
Belt wheel, motor synchronous belt wheel and timing belt, the main shaft are arranged on main spindle box, and main shaft is provided with main shaft synchronous pulley, support
Seat is fixed on main spindle box, and installing plate is bolted on support base, and motor is fixed on a mounting board, the output shaft of motor
It is provided with motor synchronous belt wheel, is connected between the synchronous pulley on motor and main shaft by timing belt, the motor synchronous belt wheel
For stepped ramp type, diameter is up big and down small, and main shaft synchronous pulley is corresponding a diameter of up-small and down-big, described one end that plate is fixedly mounted
Bolt hole is long lumbar hole.
Further, the support base both ends are provided with the boss that plate is fixedly mounted.
Further, the motor synchronous belt wheel is located between the boss below installing plate.
Further, the long lumbar hole is arc.
Further, the support base is provided with clamp pedestal, and clamp pedestal is provided with extension spring, extension spring one end and clamp phase
Even.
Further, the clamp is provided with the neck coordinated with main shaft.
The utility model has the advantages that：One end sets arc long lumbar hole on motor mounting plate, adjusts the side of getting up
Just it is quick；It is in order to ensure safety during manual shifting to set clamp, and during gearshift, the neck of clamp is stuck on main shaft, can be with
Prevent main shaft from being rotated because of maloperation；The utility model is simple in construction, easy to operate, and production cost is low.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the utility model Fig. 1 top view.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As illustrated, a kind of CNC milling machine main shaft gearshift, including main spindle box 1, support base 2, motor 3, installing plate 4,
Main shaft 5, main shaft synchronous pulley 6, motor synchronous belt wheel 7 and timing belt 8, the main shaft 5 are arranged on main spindle box 1, set on main shaft 5
There is main shaft synchronous pulley 6, support base 2 is fixed on main spindle box 1, and installing plate 4 is fixed on support base 2 by bolt 11, motor 3
It is fixed on installing plate 4, the output shaft of motor 3 is provided with motor synchronous belt wheel 7, between the synchronous pulley on motor 3 and main shaft 5
It is connected by timing belt 8, the motor synchronous belt wheel 7 is stepped ramp type, and diameter is up big and down small, and main shaft synchronous pulley 6 is corresponding
A diameter of up-small and down-big, the end bolt holes that plate 4 is fixedly mounted are long lumbar hole 12.
The both ends of support base 2 are provided with the boss that plate 4 is fixedly mounted.
The motor synchronous belt wheel 7 is located between the boss of the lower section of installing plate 4.
The long lumbar hole 12 is arc.
The support base 2 is provided with clamp pedestal 23, and clamp pedestal 23 is provided with extension spring 22, the one end of extension spring 22 and clamp 21
It is connected.
The clamp 21 is provided with the neck coordinated with main shaft 5.
Specifically, when timing belt 8 be located at motor 3 and main shaft 5 synchronous pulley appear on the stage terrace when, main shaft 5 is in top gear
Position state, during work, is driven by motor 3, and being driven main shaft 5 by synchronous pulley, timing belt 8 rotates at a high speed, and main shaft 5 drives
Milling Process is realized in cutter rotation installed in lower section.When the larger material of workhardness is, it is necessary to when changing to low gear.First stop
Machine, the neck of clamp 21 is blocked into main shaft 5, then unclamp the bolt 11 that long lumbar hole 12 is fixed on installing plate 4, be rotatablely installed plate 4, will
The timing belt 8 of release is changed on the leave from office terrace of synchronous pulley, is rotated further by installing plate 4 to be tensioned timing belt 8, is tightened fixing bolt
11, realize that the high speed gear of CNC milling machine main shaft 5 changes to low gear.
