Further, in front and back drive shaft connection arrangement also includes at least one support fixture；Front propeller shaft is located at propclip
On tool.
Specifically, in front and back drive shaft connection arrangement also includes at least one compressing fixture；Front propeller shaft is located at support fixture
And compressing fixture between.
Specifically, compressing fixture is connected with its compression of control or unclamps the drive mechanism of front propeller shaft.
Specifically, drive mechanism is cylinder；It is alternatively other and drives the reciprocating drive mechanism of compressing fixture.
Specifically, support fixture and compressing fixture are V-type；It is alternatively the shape that other have opening, and deeper width
Degree is less.
Compared with prior art, the invention has the advantages that：The free end difference of front propeller shaft and rear standard axle
Dynamic balance jig is connected with by end flange fork, makes the dynamic balancing when in use of front propeller shaft and rear standard axle more steady, no
It is also easy to produce imbalance overproof, so as to reduce the appearance of front propeller shaft and rear standard axle jitter conditions, makes power transmission more steady
It is fixed, do not affect the processing of part；Support fixture and compressing fixture make front propeller shaft and rear standard axle more stable, are difficult shake,
Reduce the rigging error after the mismachining tolerance of part, and assembling.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
In above-mentioned accompanying drawing, the corresponding component names of reference are as follows：
1- front propeller shafts, standard axle after 2-, 3- end flanges fork, the links of 4- first, the links of 5- second, 6- is supported
Frame, 7- intermediate flanges fork, 8- support fixtures, 9- compressing fixtures, 10- cylinders.
Specific embodiment
With reference to the accompanying drawings and examples the invention will be further described, and embodiments of the present invention are included but is not limited to
The following example.
Embodiment 1
As shown in figure 1, drive shaft connection arrangement includes front propeller shaft 1 and the rear standard axle 2 being connected with each other before and after a kind of；Before
Intermediate flange fork 7 is connected between the connection end of power transmission shaft 1 and rear standard axle 2；The free end of front propeller shaft 1 and rear standard axle 2
End flange fork 3 is respectively connected with, end flange fork 3 is connected with dynamic balance jig；Dynamic balance jig includes arranged in parallel
First link 4 and the second link 5；Bracing frame 6 is connected between first link 4 and the second link 5；End flange is pitched
3 have prong；First link 4 is connected with the prong of end flange fork 3；First link 4 leads to the prong of end flange fork 3
Cross mode connects for screw.
Embodiment 2
As shown in figure 1, the present embodiment is with the difference of embodiment 1, in front and back drive shaft connection arrangement is also included at least
One support fixture 8；Front propeller shaft 1 is located on support fixture 8；In front and back drive shaft connection arrangement also includes at least one pressing clip
Tool 9；Front propeller shaft 1 is located between support fixture 8 and compressing fixture 9；Compressing fixture 9 is connected with control, and it compresses or unclamps forward pass
The drive mechanism of moving axis 1.
Wherein, the quantity of support fixture 8 and compressing fixture 9 all in accordance with actually used it needs to be determined that；Drive mechanism is cylinder
10；It is alternatively other and drives the reciprocating drive mechanism of compressing fixture 9；Support fixture 8 and compressing fixture 9 are V-type；Its
Alternatively other have the shape of opening, and deeper width is less；Cylinder 10 is arranged on the top of compressing fixture 9, and control is thereon
Lower motion, support fixture 8 supports front propeller shaft 1 and rear standard axle 2, compressing fixture 9 to move downward compression front propeller shaft 1 and rear mark
Fiducial axis 2.
Following table is multigroup same type power transmission shaft before balance, existing balance mode, after the balance mode balance of the present invention
Dynamic balancing measurement data；Its technical requirements often holds residual unbalance, 150g.cm, shaft diameter about 70cm for power transmission shaft, that is, be driven
The amount of unbalance at axle two ends is needed less than 21.4g, and rotation speed requirements are less than 2200r/min；
As the table shows, the power transmission shaft of balance mode of the invention balance necessarily meets technical requirements, and existing mode is balanced
Power transmission shaft meet the probability of technical requirements less than the power transmission shaft that mode of the present invention is balanced；Now directly using through balance calibration
Front propeller shaft 1 carries out entrucking and uses, and because there is rigging error, its error when entrucking is used of front propeller shaft 1 is easily above standard model
Enclose, need to recalibrate, process is troublesome；The rear standard axle 2 of the connection of front propeller shaft 1 plays school to front propeller shaft 1 in the present invention
Positive interaction, front propeller shaft 1 has intermediate supports section, and support fixture 8 and compressing fixture 9 are respectively acting on intermediate supports section, and front
The free end of power transmission shaft 1 and rear standard axle 2 is connected with dynamic balance jig by end flange fork 3 respectively, power is transmitted more
Stable, the present invention simulates completely the entrucking state of front propeller shaft 1, makes the error that front propeller shaft 1 is produced when entrucking is used exist
In critical field.
As shown in figure 1, the present invention is when in use, the free end of front propeller shaft 1 and rear standard axle 2 passes through respectively end flange
Fork 3 is connected with dynamic balance jig, makes the dynamic balancing when in use of front propeller shaft 1 and rear standard axle 2 more steady, is not likely to produce injustice
Weighing apparatus is overproof, so as to reduce the appearance of front propeller shaft 1 and the jitter conditions of rear standard axle 2, makes power transmission more stable, does not affect
The processing of part；Support fixture 8 and compressing fixture 9 make front propeller shaft 1 and rear standard axle 2 more stable, are difficult shake, reduce
Rigging error after the mismachining tolerance of part, and assembling.
According to above-described embodiment, the present invention just can be well realized.What deserves to be explained is, before said structure design
Put, be to solve same technical problem, even if some made in the present invention are adopted without substantial change or polishing
Technical scheme essence still as the present invention, therefore it should also be as within the scope of the present invention.
