Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of speed governing simple, and the lathe-head gearbox operating mechanism that variable-ratio scope is large.
For achieving the above object, technical scheme of the present invention is:
Lathe-head gearbox operating mechanism, comprise power shaft, output shaft and speed governing axle, described power shaft is provided with driving gear, described output shaft is provided with driven gear, also be provided with cylindrical cam, first fork, second fork, shift fork and guide post, described cylindrical cam is provided with two curved grooves, described guide post and speed governing axle are arranged in parallel, guide post is slidably connected two described shift forks, a shift fork blocks a gear of triple gear, another shift fork blocks a gear of dual gear, be hinged on casing in the middle part of described first fork and the second fork, and be positioned at cylindrical cam both sides, first fork one end and hinged with the shift fork of its homonymy, the other end inserts a curved groove of cylindrical cam, second fork one end and hinged with the shift fork of its homonymy, the other end inserts another curved groove of cylindrical cam, described speed governing axle is respectively equipped with the triple gear of engagement driving gear and the dual gear of engagement driven gear, both are slidably connected with speed governing axle.
When adopting technique scheme, power shaft rotates under the drive of motor, driving gear on power shaft engages with the triple gear on speed governing axle, so triple gear is driven rotation, speed governing axle rotates thereupon, dual gear on speed governing axle rotates with speed governing axle, dual gear engages with the driven gear on output shaft again, so dual gear drives driven gear to rotate, last driven gear drives output shaft rotation, output power, during speed governing, only need rotary cylinder cam, because first fork one end is inserted in a curved groove of cylindrical cam, second fork inserts in another curved groove, first fork and the second fork are hinged on casing, so in rotary cylinder cam process, two curved grooves promote the first fork and the rotation of the second fork respectively, first fork rotation then can be stirred one of them shift fork and be slided on the guide bar, second fork rotation then can be stirred another shift fork and be slided on the guide bar, the shift fork blocking triple gear slides and triple gear then can be driven to slide on speed governing axle, thus conversion and driving gear meshed gears, simultaneously, the shift fork blocking dual gear slides and dual gear then can be driven to slide on speed governing axle, thus conversion and driven gear meshed gears.So far, complete speed-change process is just completed once.The present invention, can adjusted in concert triple gear and dual gear by cylindrical cam, the first fork, the second fork, guide post and shift fork, thus completes speed-change process once, so speed governing is simple; In addition, what engage with driving gear is triple gear, and what engage with driven gear is dual gear, and can realize multi-change speed, slewing range is larger.
Further, described cylindrical cam outer end is provided with cursor.By cursor rotary cylinder cam, rotation process is more laborsaving.
Further, the position of described cylindrical cam inside cursor is provided with baffle plate.Being provided with baffle plate can prevent hand in operating process from stretching in gearbox by mistake.
Further, described speed governing axle is splined shaft.Splined shaft has the effect preventing triple gear and dual gear from rotating relative spline shaft.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of lathe-head gearbox operating mechanism embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: splined shaft 1, triple gear 2, dual gear 3, shift fork 4, curved groove 5, second fork 6, cylindrical cam 7, cursor 8, first fork 9, guide post 10, baffle plate 11.
As shown in Figure 1, a kind of lathe-head gearbox operating mechanism, comprise power shaft, output shaft and speed governing axle, speed governing axle in the present embodiment is splined shaft 1, power shaft is provided with driving gear, output shaft is provided with driven gear, also be provided with cylindrical cam 7, first fork 9, second fork 6, shift fork 4 and guide post 10, cylindrical cam 7 is provided with two curved grooves 5, guide post 10 and splined shaft 1 are arranged in parallel, guide post 10 is slidably connected two shift forks 4, a shift fork 4 blocks a gear of triple gear 2, another shift fork 4 blocks a gear of dual gear 3, be hinged on casing in the middle part of first fork 9 and the second fork 6, and be positioned at cylindrical cam 7 both sides, first fork 9 one end and hinged with the shift fork 4 of its homonymy, the other end inserts a curved groove 5 of cylindrical cam 7, second fork 6 one end and hinged with the shift fork 4 of its homonymy, the other end inserts another curved groove 5 of cylindrical cam 7, splined shaft 1 is respectively equipped with the triple gear 2 of engagement driving gear and the dual gear 3 of engagement driven gear, both are slidably connected with splined shaft 1.Cylindrical cam 7 outer end is provided with cursor 8.By cursor 8 rotary cylinder cam 7, rotation process is more laborsaving.
