The content of the invention
For the defect that above-mentioned prior art is present, it is an object of the invention to provide a kind of speed governing is simple, and also it is variable
The big lathe-head gearbox operating mechanism of fast scope.
To reach above-mentioned purpose, the technical scheme is that：
Lathe-head gearbox operating mechanism, including input shaft, output shaft and speed governing axle, the input shaft is provided with actively
Gear, the output shaft is provided with driven gear, is additionally provided with cylindrical cam, the first fork, the second fork, shift fork and guide post,
The cylindrical cam is provided with two curved grooves, and the guide post is arranged in parallel with speed governing axle, is slidably connected on guide post two
The shift fork a, shift fork blocks a gear of triple gear, and another shift fork blocks a gear of dual gear, described
First fork and the second fork middle part be hinged on casing, and positioned at cylindrical cam both sides, first fork one end and with its homonymy
Shift fork be hinged, the other end inserts a curved groove of cylindrical cam, second fork one end and is hinged with the shift fork of its homonymy, separately
Another curved groove of cylindrical cam is inserted in one end, the triple gear of engagement driving gear is respectively equipped with the speed governing axle and is nibbled
The dual gear of driven gear is closed, both and speed governing axle slidable connection.
During using above-mentioned technical proposal, input shaft is rotated under the drive of motor, the driving gear on input shaft with adjust
Triple gear engagement on fast axle, so triple gear is driven rotation, speed governing axle concomitant rotation, the dual gear on speed governing axle
Rotate with speed governing axle, dual gear is engaged with the driven gear on output shaft again, so dual gear drives driven gear to rotate,
Last driven gear drives output shaft rotation, outputs power, during speed governing, it is only necessary to rotary cylinder cam, due to the first fork
In one curved groove of one end insertion cylindrical cam, the second fork is inserted in another curved groove, the first fork and the second fork
It is hinged on casing, so during rotary cylinder cam, two curved grooves promote respectively the first fork and the second fork to rotate,
The rotation of first fork can then stir one of shift fork and slide on the guide bar, and the second fork is rotated and can then stir another shift fork
Slide on the guide bar, blocking the shift fork slip of triple gear can then drive triple gear to slide on speed governing axle, so as to convert
With driving gear meshed gears, meanwhile, the shift fork for blocking dual gear slides and can then drive dual gear sliding on speed governing axle
It is dynamic, so as to convert and driven gear meshed gears.So far, complete speed-change process is just completed once.The present invention is by circle
Post cam, the first fork, the second fork, guide post and shift fork, can be adjusted in synchronism triple gear and dual gear, so as to one
Secondary property speed-change process is completed, so speed governing is simple；In addition, what is engaged with driving gear is triple gear, nibble with driven gear
What is closed is dual gear, it is possible to achieve multi-change speed, slewing range is bigger.
Further, the cylindrical cam outer end is provided with cursor.By cursor rotary cylinder cam, rotation process is more saved
Power.
Further, position of the cylindrical cam on the inside of cursor is provided with baffle plate.Being provided with baffle plate can prevent operating process
Middle handss are stretched in change speed gear box by mistake.
Further, the speed governing axle is splined shaft.Splined shaft has prevents triple gear and dual gear rotation from spending relatively
The effect of key axle.
Description of the drawings
Fig. 1 is the schematic diagram of lathe-head gearbox operating mechanism embodiment of the present invention.
Specific embodiment
Below by specific embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Splined shaft 1, triple gear 2, dual gear 3, shift fork 4, curved groove 5,
Second fork 6, cylindrical cam 7, cursor 8, the first fork 9, guide post 10, baffle plate 11.
As shown in figure 1, a kind of lathe-head gearbox operating mechanism, including input shaft, output shaft and speed governing axle, this enforcement
Speed governing axle in example is splined shaft 1, and input shaft is provided with driving gear, and output shaft is provided with driven gear, is additionally provided with cylinder convex
The 7, first fork 9 of wheel, the second fork 6, shift fork 4 and guide post 10, cylindrical cam 7 is provided with two curved grooves 5, guide post 10 with
Splined shaft 1 is arranged in parallel, and be slidably connected two shift forks 4 on guide post 10, and a shift fork 4 blocks a gear of triple gear 2,
Another shift fork 4 blocks a gear of dual gear 3, and the first fork 9 and the middle part of the second fork 6 are hinged on casing, and position
It is hinged in the both sides of cylindrical cam 7, the one end of the first fork 9 and with the shift fork 4 of its homonymy, one of other end insertion cylindrical cam 7
Curved groove 5, the one end of the second fork 6 and is hinged with the shift fork 4 of its homonymy, and the other end inserts another curved groove of cylindrical cam 7
5, the triple gear 2 of engagement driving gear and the dual gear 3 of engagement driven gear, both and flower are respectively equipped with splined shaft 1
The slidable connection of key axle 1.The outer end of cylindrical cam 7 is provided with cursor 8.By the rotary cylinder cam 7 of cursor 8, rotation process is more
It is laborsaving.
The outer end of cylindrical cam 7 is provided with cursor 8.By the rotary cylinder cam 7 of cursor 8, rotation process is more laborsaving.
Cylindrical cam 7 is provided with baffle plate 11 in the position of the inner side of cursor 8.Being provided with baffle plate 11 can prevent handss in operating process from missing
In stretching into change speed gear box.
Concrete operating principle：
Input shaft is rotated under the drive of motor, and the driving gear on input shaft is nibbled with the triple gear 2 on splined shaft 1
Close, so triple gear 2 is driven rotation, the concomitant rotation of splined shaft 1, the dual gear 3 on splined shaft 1 is rotated with splined shaft 1,
Dual gear 3 is engaged with the driven gear on output shaft again, so dual gear 3 drives driven gear to rotate, last driven tooth
Wheel drives output shaft rotation, outputs power, during speed governing, it is only necessary to by the rotary cylinder cam 7 of cursor 8, due to the first pendulum
