Description
Technical field
The utility model is related to a kind of mechanical stepless speed change lathes, belong to machine tool technology field.
Background technology
The universal mode of speed regulation of existing drilling machine speed governing, is the different stalls by belt pulley, generates different outer diameter ratios, from
And achieving the purpose that speed governing, this mode is comparatively laborious, and obtained speed is fixed, and optional range is small, and speed adjustable range receives
Larger limitation, therefore up for being improved.
Utility model content
The utility model is in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of upgrading to machine tool, enhances the reality of lathe
With property, reach the mechanical stepless speed-changing machine bed of variable speed.
The technical solution adopted in the utility model is thus：The stepless speed change device of the utility model lathe includes tooth shaft
（7）And and tooth shaft（7）The lifting shaft of cooperation（4）, the lifting shaft（4）Upper and tooth shaft（7）Corresponding one section is provided with rack,
The tooth shaft（7）It is driven and is rotated by regulating mechanism；
The regulating mechanism includes handlebar（13）, the handlebar（13）Connect handle set（9）, the handle set（9）
Pass through flat key（10）Drive the tooth shaft（7）Operating；
The lifting shaft（4）Top passes through shift fork（3）Stir main shaft wheel（2）Movement, makes main shaft wheel（2）Two correspond to tapers
The distance of disk changes.
The tooth shaft（7）For Step Shaft, the handle set（9）It is arranged in tooth shaft（7）Small axis on, the tooth shaft（7）It is small
Shaft end is provided with the limit handle set（9）Plain washer（11）And pass through locking nut（12）Locking.
Conflict is additionally provided on the small axis in tooth shaft（7）Baffle on step surface（8）, the handle set（9）Setting exists
The plain washer one（11）And baffle（8）Between.
The lifting shaft（4）And shift fork（3）Between pass through holding screw（5）It is attached.
The utility model has the advantages that：The utility model increases a set of stepless speed change device and one group of speed change belt wheel, to
It can obtain the arbitrary speed in a range；Stepless speed change device, including lifting structure and adjustment structure, lifting are to pass through tooth
Axis and toothrow are realized；The adjusting of lifting is to do circular motion by handlebar, and compact-sized rationally operation is simple and reliable,
With good practicability.
Description of the drawings

Fig. 2 is the side view of Fig. 1.
1 it is belt in figure, 2 be main shaft wheel, 3 be shift fork, 4 be lifting shaft, 5 be holding screw, 6 be motor wheel, 7 is tooth
Axis, 8 be baffle, 9 be handle set, 10 be flat key, 11 be plain washer, 12 be locking nut, 13 be handlebar.
Specific implementation mode
The stepless speed change device of the utility model lathe includes tooth shaft 7 and the lifting shaft 4 that coordinates with tooth shaft 7, the liter
On drop axis 4 and 7 corresponding one sections of tooth shaft is provided with rack, and the tooth shaft 7 is driven by regulating mechanism and rotated；
The regulating mechanism includes handlebar 13, and the handlebar 13 connects handle set 9, and the handle set 9 passes through flat key
10 drive the tooth shaft 7 to operate；
4 top of the lifting shaft is stirred main shaft wheel 2 by shift fork 3 and is moved, and the two of main shaft wheel 2 distance for corresponding to conical disc is made
It changes.
The tooth shaft 7 is Step Shaft, and the handle set 9 is arranged on the small axis of tooth shaft 7, and 7 small shaft end of the tooth shaft is set
It is equipped with the plain washer 11 for limiting the handle set 9 and is locked by locking nut 12.
The baffle 8 contradicted on 7 step surface of tooth shaft is additionally provided on the small axis, the setting of the handle set 9 is described flat
Between washer 1 and baffle 8.
It is attached by holding screw 5 between the lifting shaft 4 and shift fork 3.
When utility model works, motor wheel 6 drives main shaft wheel 2 to rotate by belt 1, during gearshift adjustment, leads to
It crosses and stirs handlebar 13, then drive tooth shaft 7 to operate by handle set 9, tooth shaft 7 and the cooperation of lifting shaft 4 drive about 4 lifting shaft
It moves, variation is then generated by distance between realizing 2 liang of conical discs of main shaft wheel the shift fork 3 of the connection of lifting shaft 4, due to liter
It can be continuous form to drop 4 elevating movement of axis, to realize the purpose of electrodeless variable-speed.
The utility model realizes being fastenedly connected for lifting shaft 4 and shift fork 3 by holding screw 5, and connection structure is simple and can
It leans on, has good practicability.
