Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
Eccentric differential gear for milling blind hole bottom surface of the present utility model, as Figure 1-3, including housing 1, Gu
On first motor 2 at housing 1 top, the output shaft 21 of described first motor 2, fixed cover is provided with the first gear 31, the first tooth
Wheel 31 is engaged with one second gear 32, and the second gear 32 is coaxially fixed with the 3rd gear 33, this second gear 32 and the 3rd gear
33 equal fixed covers are located in Coupling Shaft 22, and this Coupling Shaft 22 is fastened transversely on housing 1 by bearing 23 so that rotating shaft 22 can
Rotating relative to housing 1, the 3rd gear 33 is engaged with the 4th gear 34, by this first, second, third and fourth gear
Arrange, so that the output speed of the 4th gear 34 is adjusted to 6-10 rev/min.4th gear 34 fixed cover is located at greatly
Drive big main shaft 4 to rotate coaxially on main shaft 4, i.e. the speed of this big main shaft 4 is 6-10 rev/min.This first, second, third He
4th gear is the first gear train, and this first gear train connects the first motor 2 and big main shaft 4, and then makes the first motor 2
Export through the big main shaft of deceleration rear drive 4 around himself axial rotation.
It is fixed with in big main shaft 4 and runs through its axial primary spindle 5, between primary spindle 5 and big main shaft 4, be provided with multiple axle
Holding, this primary spindle 5 axial, line C-C as shown in Figure 1, axial with big main shaft 4, line D-D as shown in Figure 1, bias sets
Putting, the distance between both axle center is 7.4mm.Therefore, the rotation of big main shaft 4 can drive primary spindle 5 around the axle of big main shaft 4
The heart does revolution motion.
Also it is fixed with the second motor 6 on housing 1, the output shaft 61 of this second motor 6 is coaxially fixed with the first band
Wheel 71, is cased with Timing Belt 72 outside this first belt wheel 71, the opposite side of Timing Belt 72 connects the second belt wheel 73, this second belt wheel
73 are sheathed on big main shaft 4 by bearing 78, and therefore, the rotation of this big main shaft 4 and the rotation of the second belt wheel 73 be not mutually by shadow
Ring.Outside the end of primary spindle 5, coaxial fixed cover is provided with driver plate 74, and this driver plate 74 is provided with multiple groove radially extended
741, this groove 741 is inserted into being provided with thumb wheel axle 75, and the width of this groove 741 and thumb wheel axle 75 match and this thumb wheel axle 75 can edge
The length direction motion of groove 741, is connected by bearing between this thumb wheel axle 75 with groove 741 and this thumb wheel axle 75 and second belt wheel
73 fixing connect, therefore, when the second belt wheel 73 under the driving of the second motor 6 around the axial rotation of big main shaft 4 time, it is possible to pass through
Thumb wheel axle 75 moves along groove 741, drives thumb wheel axle 75 to rotate, and drives this primary spindle 5 to rotate around the axle of himself simultaneously.Due to
Primary spindle 5 and big main shaft 4 eccentric setting, therefore, driver plate 74 and the second belt wheel 73 also eccentric setting, therefore, the second belt wheel 73
Rotating through while thumb wheel axle 75 drives driver plate 74 and primary spindle 5 to rotate, this thumb wheel axle 75 can be at the groove 741 of driver plate 74
Interior work is along the moving of radial direction of driver plate 74 so that the second belt wheel 73 can drive the rotation of primary spindle 5 smoothly.
Above-mentioned first belt wheel, the second belt wheel, Timing Belt and driver plate are pulley assemblies, and this pulley assemblies connects the second motor
With primary spindle 5 and then drive primary spindle 5 around himself axial rotation.The other end of primary spindle 5 is fixing connects cutter 8, passes through
The first above-mentioned motor, big main shaft, gear assembly, the second motor, primary spindle and pulley assemblies can be carried out around greatly by band cutter 8
While the revolution of spindle axis, around himself axial rotation and then the bottom surface of blind hole being carried out milling pin, machining locus is ring
Shape face.And axially all laterally arranging in the same direction of above-mentioned big primary spindle, gear and belt wheel.Pulley assemblies, gear assembly and big
Primary spindle is all located in housing 1.
And as shown in Figure 2,3, two the 4th gears engaged with the 3rd gear can be simultaneously provided with, and be simultaneously provided with
Two blind holes are carried out milling pin by two groups of big main shafts and primary spindle simultaneously, and these two primary spindles, can corresponding different pulley assemblies
With the second motor so that the milling pin speed of different primary spindles can also be adjusted to difference.
This is used for the eccentric differential gear of milling blind hole bottom surface, drives big primary spindle by pulley assemblies and gear assembly
Motion, and then realize primary spindle and can do circulatory motion while rotation milling pin so that the machined surface of milling pin is ring surface,
Blind hole bottom surface can be carried out milling pin, and rotating speed can be regulated as required, the most easy to use but also the scope of application is wider.
Although preferred embodiment of the present utility model described in detail above, it is to be clearly understood that for this
For the technical staff in field, this utility model can have various modifications and variations.All in spirit of the present utility model and principle
Within any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
