Spindle nose 15, is provided with changeover portion 1, was provided between thread segment 2 13 and bearing pin head 15 between cylinder 11 and thread segment 2 13
Cross section 2 14.Wherein, thread segment 1 and thread segment 2 13 are the screw thread being mutually paired.So, the bearing pin connection group is not only made
Part reaches default purpose, and is easy to process.
During work, as shown in figure 1, bearing pin 1 adaptable with which is installed on axis pin base 2, by the cylinder 11 of bearing pin 1
Parts 3 are positioned.Further, in conjunction with shown in Fig. 2 and Fig. 6, the mid portion on cylinder 11 or away from screw thread
One end of section 2 13 is used for installation targets parts 3, and thread segment 2 13 is in thread segment 1, and corresponding bearing pin head
15 are also loaded onto in circular hole 25.It is apparent that the structure can be used on the lid and pedestal of docking, now, lid and pedestal are respectively and sell
Axle bed 2 or parts 3, and the relativeness of the two can exchange, i.e., and lid can be set to parts 3, pedestal and be set to bearing pin
Seat 2 or lid are set to axis pin base 2, pedestal and are set to parts 3.
Further, as shown in Fig. 2 the diameter with diameter greater than cylinder 11 of thread segment 2 13, and thread segment 2 13
On screw thread path more than or equal to cylinder 11 diameter, and thread segment 2 13 is outer with diameter greater than bearing pin head 15
Maximum outside diameter of the path of the screw thread on footpath, and thread segment 2 13 more than or equal to the appearance profile of bearing pin head 15.
Further, Fig. 3 refer to, and bearing pin head 15 is square spigot.Further, square spigot is turret head, its section
Face is regular hexagon, and each side intersection is provided with chamfering or fillet.
On the basis of above-mentioned technical proposal, further can also be improved.Specifically, as shown in fig. 6, thread segment one
23 diameter with diameter greater than pin shaft hole 21, and the path of the screw thread on thread segment 1 is more than the diameter of pin shaft hole 21.Enter
One step ground, the diameter of thread segment 1 are less than the aperture of circular hole 25, and the big footpath of the screw thread on thread segment 1 is less than circular hole
25 aperture.So, not only make the axis pin base reach initial purpose, and be easy to process.
On the basis of any of the above-described technical scheme, further can also be improved.Specifically, Fig. 4, transition refer to
Section 1 connecting cylinder body 11 and thread segment 2 13 in the form of arc transition.Further, changeover portion 2 14 adopts circular arc
The form connecting pin spindle nose 15 of transition and thread segment 2 13.Further, the path of changeover portion 2 14 is more than or equal to pin
The maximum outside diameter of the appearance profile of spindle nose 15.Yet further, the non-maximum of the appearance profile of changeover portion 2 14 and bearing pin head 15
Outer radius are again using the transient mode of rounding.
On the basis of any of the above-described technical scheme, further can also be improved.Specifically, as shown in figure 3, bearing pin
The diameter of the cylinder that the intersecting lens in the adjacent each face of 15 square spigot is located is equal to the path of changeover portion 2 14.In addition, such as Fig. 5 institutes
Show, it should be apparent that, the diameter of the cylinder at the intersection place of 15 each adjacent side of bearing pin head can be more than the little of changeover portion 2 14
Footpath, now suitably carries out chamfering to the intersection of 15 each adjacent side of bearing pin head, you can so that the path of changeover portion 2 14 is more than
Or the maximum outside diameter of the appearance profile equal to bearing pin head 15.Furthermore, it is to be understood that ground, the phase in the adjacent each face of the square spigot of bearing pin head 15
The diameter of the cylinder that intersection is located can also be suitably less than the path of changeover portion 2 14.
On the basis of any of the above-described technical scheme, further can also be improved.Specifically, as shown in fig. 6, conical ring
The diameter of the big nose end in hole 1 is identical with the size of the path of the screw thread of thread segment 1；And the small bore end in conical ring hole one
Diameter is identical with the size of the pin shaft hole.Further, the diameter of the small bore end in conical ring hole 2 24 is big with thread segment 1
The size in footpath is identical, and the diameter of the big nose end in conical ring hole 2 24 is identical with the size of the diameter of circular hole 25.
Further, as shown in Fig. 2 the screw thread on thread segment 1 is in the form of triangle thread；Equally, the screw thread
Screw thread in section 1 can also adopt rectangular thread, trapezoidal thread, saw-tooth thread or other special shape screw threads.As schemed
Shown in 6, the screw thread on thread segment 2 13 is in the form of triangle thread；Equally, the screw thread on the thread segment 2 13 can be with
Using rectangular thread, trapezoidal thread, saw-tooth thread or other special shape screw threads.Wherein, thread segment 1 and thread segment
2 12 is the screw thread being mutually paired.
On the basis of any of the above-described technical scheme, further can also be improved.Refer to Fig. 7 and Fig. 8, Fig. 7 are
The structural representation of the axis pin base provided by the 4th kind of specific embodiment in the present invention；Fig. 8 is embodied as the 4th kind for the present invention
The assembling structure schematic diagram of the bearing pin coupling assembly provided by example.
Specifically, as shown in fig. 7, pin shaft hole 21 is distributed on two journal stirrups of bearing pin pedestal 2, it is right for installing therebetween
The mounting groove of parts 3, i.e. pin shaft hole 21 is answered to be distributed in the both sides of the mounting groove.In a kind of unshowned embodiment, institute
The mounting groove that states can also be the installing hole for installing corresponding parts 3.As shown in figure 8, a part for corresponding parts 3 is arranged on
In two journal stirrups of bearing pin pedestal 2, it is hinged by bearing pin 1.It should be noted that the present invention is to the installing hole or groove
Specific constructive form do not do any restriction.Alternatively, it is also possible to be used for pacifying by way of grooving on bearing pin pedestal 2 or hole
The corresponding parts 3 of dress.
Wherein, in any of the above-described technical scheme, its one end or two ends can be arranged on by cylinder 11 as needed
In the pin shaft hole 21 of axis pin base 2.
Second purpose of the invention is to provide a kind of preparation method based on above-mentioned bearing pin coupling assembly, including bearing pin and pin
The preparation method of axle bed, the bearing pin are the bearing pin described in any of the above-described technical scheme, and the axis pin base is any of the above-described skill
Axis pin base in art scheme,
Wherein, the preparation method of bearing pin, comprises the following steps：
Step 11, the blanking that bearing pin is carried out using round steel or bar.
Step 12, the preparatory processing that lower good material is carried out appearance profile, including the appearance profile to each section of bearing pin just
Car, and leave appropriate surplus.
Step 13, carries out modifier treatment to the part through preparatory processing.
Step 14, processes the bearing pin head, each side including milling square spigot and the intersection to adjacent side
Carry out chamfering or rounding, and adopt milling cutter vertical with bearing pin but disjoint mode with directly reach the changeover portion two with
Again using the purpose of the transient mode of rounding at the non-maximum outside diameter of the appearance profile of the bearing pin head.
Step 15, processes the thread segment two, the cylinder and the changeover portion one and the changeover portion two, including
Changeover portion two and cutting thread described in changeover portion one, car described in cylinder, car described in car.Wherein described in cylinder, car described in car
Described in changeover portion one, car, the processing sequence of changeover portion two suitably can be adjusted as needed.
Step 16, carries out chamfering to disconnected section of the cylinder of end or rounding is processed.
Step 17, finishes to the cylindrical of the cylinder, to ensure that its surface roughness reaches use requirement.
