The specific embodiment
Contrast accompanying drawing below,, the specific embodiment of the utility model is done further detailed explanation, inventive concept, the technical scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art through description to embodiment.
Structure like the expressed the utility model of Fig. 1, Fig. 2 is a kind of workbench gearbox of vertical lathe, and the gear drive of described gearbox comprises belt pulley 1, output gear 9 and shifting slide gear 7, and described shifting slide gear 7 is stirred through shift fork 6.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize the infinite variable speed goal of the invention of workbench, the technical scheme that the utility model is taked is:
As shown in Figure 1; The workbench gearbox of the vertical lathe that the utility model provided; Establish two coaxial oil cylinders 4, oil cylinder 5 in the described gearbox, these two oil cylinders 4, oil cylinder 5 adopt same piston rod 2, and described shift fork 6 is installed on the piston rod 2 between two oil cylinders 4, the oil cylinder 5.
Adopt technique scheme, not only reduced the number of meshing gear, simplified the structure of casing, make the manufacturing assembling more simple, reduced the noise of casing.
The drive motors of described gearbox is the ac variable frequency speed regulation motor.Utilize the ac variable frequency speed regulation motor in the certain speed scope, to realize stepless speed regulation, and speed governing is convenient, has improved the efficient and the product precision of processing.
Described shifting slide gear 7 is that three gears connect as a whole triple gear.Realize that through triple gear three retainings expand speed change, strengthen speed adjustable range, and when intermediate speed, can obtain the bigger cutting moment of torque, fully play the power of motor.
The operation principle of the utility model:
Referring to Fig. 1:
When oil cylinder 5 gets into pressure oils, piston rod 2 drives shift forks 6 together with piston 3 and moves on to three gears and put, and also drives shifting slide gear 7 on the II axle simultaneously and moves to three gears and put and corresponding gears engaged;
When oil cylinder 4 gets into pressure oils, oil cylinder 5 not oil-feeds, then piston rod 2 drives shift forks 6 together with piston 3 and moves on to the I gear and put, and also drives shifting slide gear 7 on the II axle simultaneously and moves to the I gear and put and corresponding gears engaged;
When oil cylinder 4 and oil cylinder 5 get into pressure oil simultaneously; At this moment the diameter of piston rod 2 two ends diameters and piston 3 is different; Consequent pressure differential; Make piston rod 2 and piston 3 drive shift forks 6 and be in the II gear and put, also drive shifting slide gear 7 on the II axle simultaneously and move to the II gear and put and corresponding gears engaged;
More than be three gears, in three gears, the frequency of adjustment variable-frequency motor just can obtain different rotating speed output.
Use the effect of three retaining speed changing, frequency converting casings:
1, not only reduces the number of meshing gear, simplified the structure of casing, made the manufacturing assembling more simple, reduced the noise of casing.
2, realize vertical lathe workbench rotation stepless speed regulation, improved the efficient of processing.
3, in addition according to the characteristic of variable-frequency motor, the relation of moment of torsion, rotating speed, frequency is used three retaining speed changes; Can make when intermediate speed; Can obtain the bigger cutting moment of torque, fully play the power of motor, compare with product of the same type; The 55kw frequency conversion cabinet characteristic of our three retaining frequency conversions is equal to the height retaining frequency conversion casing of 75kw, so also play energy-conservation effect.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
