Specific implementation mode
It is below in conjunction with the accompanying drawings and real in order to be more clearly understood that the above objects, features, and advantages of the utility model
Example is applied to be described further the utility model.It should be noted that in the absence of conflict, embodiments herein and reality
The feature applied in example can be combined with each other.
Many details are elaborated in the following description in order to fully understand the utility model, still, this practicality
Novel to implement using different from other modes described here, therefore, the utility model is not limited to be described below
The limitation of the specific embodiment of specification.
Embodiment 1, as shown in Figure 1, the utility model provides a kind of positioning tool of assembly differential spider pinion shaft,
For the tooling, the trend trend of equipment at this stage, the utility model are complied in the main installation using with planetary gear shaft
The device of offer be also one can with remote control, for the tooling, including support table frame and support vertical frame, support
Table frame mainly completes the main of planetary gear shaft installation using to place differential mechanism semi-finished product, supporting then to be provided in vertical frame
Component, not ugly from Fig. 1, support vertical frame has set gradually lower propulsive mechanism, middle propulsive mechanism and upper propulsion from bottom to up
Mechanism, it is noted herein that upper propulsive mechanism and lower propulsive mechanism move above and below, and middle propulsive mechanism is then laterally
Advancing movement, but three mechanisms are relative to what differential mechanism in support table frame was configured, upper and lower propulsive mechanism
The direction of motion and the longitudinal central axis line of differential mechanism are consistent, and wherein the direction of motion of propulsive mechanism is then the transverse direction with differential mechanism
Central axes are consistent.
The specifically specific design of the propulsive mechanism of inventor's centering once below, as Figure 2-Figure 5, wherein propulsive mechanism
Include with support vertical frame connect be arranged be connected and fixed plate, for the setting for being connected and fixed plate, being can be in upper pusher
The movement of structure and move, i.e., when upper propulsive mechanism is when moving downward, under the action of being connected and fixed plate, wherein pusher
Structure integrally can also move downward, from figure 2 it can be seen that it is connected and fixed two parts that plate includes horizontal and vertical, connection is solid
The lower part of fixed board is provided with propulsion assembly, and propulsion assembly includes that the propulsion cylinder being arranged on being connected and fixed plate and setting exist
The planetary gear axle sleeve assembly on propulsion cylinder head, propulsion cylinder here are then provided in the longitudinal component being connected and fixed on plate
, planetary gear set assembly is arranged on being connected and fixed plate by slide assemblies, it is evident that its planetary gear covers assembly
It is then provided in and is connected and fixed lateral part on plate.
As shown in Fig. 3, Fig. 4, Fig. 5, for planetary gear set assembly, planetary gear axle sleeve assembly includes sheath body,
You may be considered a plate to the sheath body, then carried out workability digging processing, can also utilize structural slab into
Row splicing, but inventor is then to use the former, be in this way sheath body is more durable；From figure 5 it can be seen that its sheath body
Lateral central axes on be provided with through hole, one end is provided with piston rod inside through hole, and piston rod here is (such as Fig. 6 institutes
Show) it is then demountable, it is because being provided in through hole consistent with piston rod external structure；In addition to this, inventor
The promotion baffle that can be slided is provided with also outside the other end of through hole, from figure 5 it can be seen that pushing baffle and sheath body
Be equipped with relationship, in addition to this, push and be provided with matching hole on baffle, need to note for being provided with of matching hole
Meaning pushes the length of baffle to be wider than the width of sheath body, and thus its matching hole is not arranged in the center for promoting baffle
On position, it should remove the central point for length, specific operation principle can illustrate at operation principle below.
It is obvious that its planetary gear shaft is also provided in the through hole, internal one end and plunger rod contacts, the other end
It is then in outside, in order to which preferably planetary gear shaft is fixed, (fixation here mainly prevents from rotating inventor
Fixation), so inventor one end lower part far from piston rod inside through hole is provided with receiving hole, setting in receiving hole
Screens spring ball component, from figure 3, it can be seen that its screens spring ball component includes spring, close to passing through on spring spring
One end of perforation is provided with screens steel ball, and the other end is provided with fixed cover, and fixed cover is bolted on sheath body, such
The direction of design is also relatively good understanding, in addition to this, figure 4, it is seen that the both sides in through hole are also provided with phase
The receiving hole answered, the receiving hole are then the designs in order to coordinate other planetary gear shafts to carry out, inside be also provided with it is corresponding
Screens spring ball component, it is therefore an objective to the same.
For slide assemblies, the fixed-direction mainly to one sliding of sheath body includes that setting is connecting
The track of fixed plate bottom and the sliding block on sheath body is equipped with and is fixed on track, it is noted herein that, invention
People is then that sliding block is fixed on sheath body using stay bolt.
Setting for upper propulsive mechanism and lower propulsive mechanism is from figure 1 it appears that its specific setting, is very clear
Chu, under normal circumstances, lower propulsive mechanism is motionless, upper propulsive mechanism work, and inventor is in order to realize in upper propulsion
Intelligent operation screen is provided at mechanism, the setting of the intelligent operation screen also achieves the intelligentized design of whole device, matches therewith
Close the controllability of hydraulic cylinder in the certainly propulsion cylinder being arranged and upper and lower propulsive mechanism.
The work of the utility model is separate, first prevents in support table frame differential mechanism semi-finished product, then controls and push away
It is moved down into mechanism, is that the compression bar in upper propulsive mechanism pushes down differential casing, then middle propulsive mechanism transverse shifting, will go
Star gear shaft (planetary gear shaft has been placed in through hole by this when) is advanced in the planetary gear of differential mechanism, so
Propulsive mechanism in shifting afterwards, it is then artificial to push baffle, it is matching hole movement, i.e., what is aligned with planetary gear shaft is plate
Body, the then propulsive mechanism in control, therefore planetary gear shaft is advanced to required position.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of variation is applied to other fields, but every without departing from the content of the technical scheme of the utility model, according to this reality
With novel technical spirit to any simple modification, equivalent variations and remodeling made by above example, it is new to still fall within this practicality
The protection domain of type technical solution.
