[0051] Before explaining the technical solution of the present application, the technical background of the present application is first explained.

[0052] The shift fork assembly 200 is a general term for an assembly formed after the shift fork shaft B is assembled to the shift fork A. It is an indispensable component in the automatic transmission of an automobile, and therefore, the demand for it is huge. Figure 1 is a structural schematic diagram of a fork assembly 200 provided in an embodiment of the present application. Figure 2 yes Figure 1 Exploded view of the fork assembly 200 in FIG. Figure 1 and Figure 2 When assembling the fork assembly 200, the fork shaft B needs to be inserted into the mounting hole A2 of the fork A first, and then the fork shaft B needs to be manually rotated around the axis of the fork shaft B to adjust the phase between the fork shaft B and the fork A so that the first pin hole A1 on the fork A is aligned with the second pin hole B1 on the fork shaft B to form a connected pin hole C. Finally, the corrugated pin D is manually inserted into the connected pin hole C and the cotter pin E is inserted into the through hole D1 of the corrugated pin D to achieve the purpose of assembling the fork assembly 200.

[0053] However, when manually adjusting the phase between the shift fork A and the shift fork shaft B so that the first pin hole A1 on the shift fork A is aligned with the second pin hole B1 on the shift fork shaft B, the personnel must closely monitor the alignment of the first pin hole A1 on the shift fork A and the second pin hole B1 on the shift fork shaft B. This is heavily dependent on the personnel's operating experience and the adjustment process is also slow, which affects the assembly efficiency of the shift fork assembly 200. Based on this, there is an urgent need for an automatic pressing device 100 for the shift fork assembly to solve the above problem.

[0054] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0055] Figure 3 1 is a schematic diagram of the structure of a fork assembly automatic press-fitting device 100 provided in one embodiment of the present application. Figure 4 yes Figure 3 The structural diagram of the positioning platform 1 along the positive viewing angle of the Y axis is shown in FIG. Figure 3 and Figure 4 The automatic press-fitting device 100 for the shift fork assembly comprises: a positioning platform 1, a latch assembly 2 and a pressing head mechanism 3, wherein the positioning platform 1 is used to install the shift fork A so that the first pin hole A1 of the shift fork A is along the first direction ( Figure 4 The mounting hole A2 of the shift fork A extends in a direction perpendicular to the first direction ( Figure 4 The mounting hole A2 is used for the shift fork shaft B to be inserted therein, and the shift fork shaft B can rotate relative to the shift fork A around the axis of the mounting hole A2, so that the second pin hole B1 and the first pin hole A1 can be aligned to form a connected pin hole C. The latch assembly 2 is arranged on the positioning platform 1, and the latch assembly 2 includes a latch driving member 21 and a latch 22. The latch driving member 21 is used to provide the latch 22 with a positive direction ( Figure 4 The driving force of the positive direction of the Z axis) is used to enable the latch 22 to move along the first end of the communicating pin hole C ( Figure 4 The bottom end of the connecting pin hole C in the middle) is inserted into the connecting pin hole C, and the pressure head mechanism 3 is used to move the corrugated pin D in the opposite direction of the first direction ( Figure 4 The Z-axis is in the opposite direction) from the second end of the connecting pin hole C ( Figure 4 The top end of the connecting pin hole C in the middle) is inserted into the connecting pin hole C, and the open pin E is inserted into the through hole D1 of the corrugated pin D in the reverse direction of the first direction, wherein the insertion force of the pressure head mechanism 3 is greater than the driving force of the pin driving member 21.

[0056] In this embodiment, when assembling the fork assembly 200, first, the fork A can be installed on the positioning platform 1. When installing the fork A, it is necessary to ensure that the first pin hole A1 of the fork A extends along the first direction and the mounting hole A2 of the fork A extends along a direction perpendicular to the first direction. Then, the fork shaft B can be inserted into the mounting hole A2. After the fork shaft B is inserted into the mounting hole A2, the fork shaft B can be rotated around the axis of the mounting hole A2 to adjust the phase between the fork shaft B and the fork A. When the phase between the fork shaft B and the fork A is adjusted to the point where the first pin hole A1 on the fork A is aligned with the second pin hole B1 on the fork shaft B to form a connected pin hole C, the latch drive member 21 can provide the latch 22 with a positive direction ( Figure 4 Therefore, under the premise that the first pin hole A1 on the fork A is aligned with the second pin hole B1 on the fork shaft B to form a connected pin hole C, the latch driving member 21 will be able to drive the latch 22 along the first end ( Figure 4 The bottom end of the connecting pin hole C in the middle) is inserted into the connecting pin hole C.

[0057] After the latch 22 is inserted into the connecting pin hole C, the latch 22 will string the fork shaft B and the fork A together, so that the phase between the fork shaft B and the fork A is fixed. At this time, under the fixing action of the latch 22, the fork shaft B will not be able to continue to rotate, thereby ensuring that the first pin hole A1 on the fork A and the second pin hole B1 on the fork shaft B can be aligned together to form a connecting pin hole C. Next, the corrugated pin D can be inserted into the connected pin hole C from the second end of the connected pin hole C in the opposite direction of the first direction by the pressing head mechanism 3. Since the insertion force of the pressing head mechanism 3 is greater than the driving force of the latch driver 21, during the process of the pressing head mechanism 3 inserting the corrugated pin D from the second end of the connected pin hole C into the connected pin hole C in the opposite direction of the first direction, the corrugated pin D will slowly enter the connected pin hole C in the opposite direction of the first direction, and the latch 22 will slowly be squeezed out of the connected pin hole C in the opposite direction of the first direction until the corrugated pin D is inserted into the connected pin hole C as a whole. Finally, the pressing head mechanism 3 can insert the cotter pin E into the through hole D1 of the corrugated pin D in the opposite direction of the first direction. At this point, the shift fork A and the shift fork shaft B are fixed, thereby completing the assembly of the shift fork assembly 200.

[0058] Among them, since in the process of rotating the fork shaft B around the axis of the mounting hole A2 on the fork A, when the first pin hole A1 on the fork A is rotated to align with the second pin hole B1 on the fork shaft B to form a connecting pin hole C, the pin 22 will be able to be automatically inserted into the connecting pin hole C along the first end of the connecting pin hole C under the driving action of the pin driving member 21, and when the pin 22 is inserted into the connecting pin hole C, the fork shaft B will not be able to continue to rotate. In this way, the personnel can judge whether the first pin hole A1 on the fork A and the second pin hole B1 on the fork shaft B are aligned by whether the fork shaft B can continue to be rotated, so that the personnel do not need to keep a close eye on the alignment of the first pin hole A1 on the fork A and the second pin hole B1 on the fork shaft B. On the one hand, it can reduce the dependence on the operating experience of the personnel, and on the other hand, it can also improve the phase adjustment process to a certain extent, thereby improving the assembly efficiency of the fork assembly 200.

[0059] In addition, since the corrugated pin D will slowly enter the connected pin hole C in the opposite direction of the first direction when the pressure head mechanism 3 inserts the corrugated pin D from the second end of the connected pin hole C into the connected pin hole C in the opposite direction of the first direction, and the plug 22 will slowly be squeezed out of the connected pin hole C in the opposite direction of the first direction, after the corrugated pin D completely enters the connected pin hole C, the plug 22 will be completely squeezed out of the connected pin hole C and located at the first end of the connected pin hole C. At this time, when the cotter pin E is inserted into the through hole D1 of the corrugated pin D in the opposite direction of the first direction by the pressure head mechanism 3, the plug 22 can block the corrugated pin D at the first end of the connected pin hole C, which can avoid the situation that the corrugated pin D is squeezed out of the connected pin hole C in the opposite direction of the first direction during the insertion of the cotter pin E, and ensure that the corrugated pin D can always be located in the connected pin hole C, thereby avoiding the situation that the corrugated pin D is abnormally squeezed out.

[0060] There are many ways to implement the latch drive 21. In one possible implementation, the latch drive 21 may be a cylinder. In another possible implementation, see Figure 4 , the latch driving member 21 is an elastic member.

[0061] When the latch driving member 21 is an elastic member, before the first pin hole A1 on the fork A is not aligned with the second pin hole B1 on the fork shaft B, the latch driving member 21 can be in a compressed state. When the first pin hole A1 on the fork A is aligned with the second pin hole B1 on the fork shaft B, the latch driving member 21 can gradually recover from the compressed state to the natural state. In the process of recovering from the compressed state to the natural state, the latch driving member 21 can provide the latch 22 with a positive force ( Figure 4 The driving force of the connecting pin 22 is applied in the positive direction of the Z axis, thereby achieving the purpose of inserting the plug 22 into the connecting pin hole C along the first end of the connecting pin hole C.

[0062] It can be seen that when the latch driving member 21 is an elastic member, the latch driving member 21 provides the latch 22 with a positive force ( Figure 4 The method of providing the driving force in the positive direction of the Z axis is very simple, and therefore, the cost of the latch driving member 21 can be reduced to a certain extent.

[0063] In order to make the latch 22 move more steadily and smoothly along the first direction, in some embodiments, see Figure 4 The latch assembly 2 also includes: a guide member 23, which is arranged on the positioning platform 1, and a guide hole 231 is arranged on the guide member 23 along the first direction to penetrate the guide member 23, and the latch 22 is slidably arranged in the guide hole 231 along the extension direction of the guide hole 231.

[0064] Since the guide hole 231 penetrates the guide member 23 along the first direction, the latch 22 is slidably disposed in the guide hole 231 along the extension direction of the guide hole 231. Therefore, under the guiding effect of the guide hole 231, the latch 22 can move more steadily and smoothly along the first direction.

[0065] In some embodiments, see Figure 4 The plug 22 is provided with a guide matching portion 221, which protrudes from the plug 22 along the radial direction of the plug 22, and the guide matching portion 221 is slidably provided in the guide hole 231 along the first direction, and a blocking portion 2311 is provided on the hole wall of the guide hole 231, and the blocking portion 2311 is located on the side of the guide matching portion 221 away from the pressure head mechanism 3 ( Figure 4 The elastic member is sandwiched between the guide matching portion 221 and the blocking portion 2311 along the first direction.

[0066] Since the elastic member is clamped between the guide matching portion 221 and the blocking portion 2311 along the first direction, before the first pin hole A1 on the fork A and the second pin hole B1 on the fork shaft B are not aligned, the elastic member can be clamped by the guide matching portion 221 and the blocking portion 2311 along the first direction, so that the elastic member is in a compressed state. After the first pin hole A1 on the fork A and the second pin hole B1 on the fork shaft B are aligned, the elastic member clamped between the guide matching portion 221 and the blocking portion 2311 along the first direction can be moved in the positive direction ( Figure 4 The positive direction of the middle Z axis) applies elastic force to the guide matching portion 221, thereby achieving the purpose of driving the plug pin 22 to be inserted into the connecting pin hole C from the first end of the connecting pin hole C along the positive direction of the first direction.

[0067] In some embodiments, see Figure 4The elastic member is a spring, and the spring is sleeved on the latch 22. By sleeved on the latch 22, the latch 22 can limit the spring during the compression of the spring, thereby avoiding the situation that the spring tilts.

[0068] It can be understood that when the latch assembly 2 includes the latch driving member 21, the latch 22 and the guide member 23, and the latch driving member 21 is a spring, the structure formed by the latch assembly 2 as a whole is a spring pin structure.

[0069] Since the spring pin structure technology is mature and the cost is low, the cost of the latch assembly 2 can be reduced while ensuring the operational reliability of the latch assembly 2.

[0070] In order to more accurately determine whether the plug pin 22 is inserted into the communicating pin hole C, in some embodiments, see Figure 4 The automatic press-fitting device 100 for the fork assembly further includes: a detection component 4, which is used to detect whether the latch 22 is inserted into the communicating pin hole C.

[0071] Since the detection component 4 can detect whether the latch pin 22 is inserted in the connecting pin hole C, in addition to judging whether the latch pin 22 is inserted in the connecting pin hole C by whether the fork shaft B can continue to rotate around the axis of the mounting hole A2, the detection component 4 can be used to further assist in the judgment, and then it can be more accurately judged whether the latch pin 22 is inserted in the connecting pin hole C, thereby avoiding misjudgment.

[0072] For example, assuming that the fork shaft B cannot continue to rotate around the axis of the mounting hole A2 due to sticking or other reasons, at this time, if it is determined that the latch 22 is inserted in the connecting pin hole C, it is obviously a misjudgment. In order to avoid such a misjudgment, on this basis, the detection component 4 can be used to detect whether the latch 22 is inserted in the connecting pin hole C, thereby achieving a double insurance effect, and then it can be more accurately determined whether the latch 22 is inserted in the connecting pin hole C, reducing the possibility of misjudgment.

[0073] The detection assembly 4 may be a variety of possible structures or components, as long as it can detect whether the plug 22 is inserted into the connecting pin hole C. This embodiment does not limit this. In one possible implementation, the detection plug 22 may be a CCD (Charge coupled Device) camera. In another possible implementation, see Figure 4 The detection assembly 4 includes: a first position detection sensor 41 and a sensing element 42, wherein the first position detection sensor 41 is arranged on the positioning platform 1, and the sensing element 42 is arranged on the latch 22, and the latch 22 moves in the positive direction of the first direction ( Figure 4When the latch 22 is inserted into the communicating pin hole C along the positive direction of the Z axis, the sensing element 42 is located within the detection range of the first position detection sensor 41, and the latch 22 moves in the reverse direction of the first direction ( Figure 4 When the sensing element 42 exits the communicating pin hole C (in the negative direction of the center Z axis), the sensing element 42 is located outside the detection range of the first position detection sensor 41.

[0074] Since the sensing member 42 is disposed on the latch 22, when the latch 22 is inserted into the communicating pin hole C in the forward direction of the first direction or withdraws from the communicating pin hole C in the reverse direction of the first direction, the sensing member 42 disposed on the latch 22 will be driven to reciprocate in the first direction. During the reciprocating motion of the sensing member 42 in the first direction, the sensing member 42 may enter the detection range of the first position detection sensor 41 so that the first position detection sensor 41 may detect the sensing member 42, or the sensing member 42 may move out of the detection range of the first position detection sensor 41 so that the first position detection sensor 41 may not detect the sensing member 42.

[0075] Next, when the latch 22 is moved in the positive direction ( Figure 4 When the latch 22 is inserted into the communicating pin hole C along the positive direction of the Z axis, the sensing element 42 is located within the detection range of the first position detection sensor 41. When the latch 22 is moved in the reverse direction of the first direction ( Figure 4 When the latch 22 exits the connected pin hole C (in the negative direction of the center Z axis), the sensing part 42 is outside the detection range of the first position detection sensor 41. Therefore, when the first position detection sensor 41 detects the sensing part 42, it can be determined that the latch 22 is inserted in the connected pin hole C at this time. When the first position detection sensor 41 cannot detect the sensing part 42, it can be determined that the latch 22 is at this time.

[0076] It can be seen that the first position detection sensor 41 can determine whether the pin 22 is inserted into the connecting pin hole C by detecting whether the sensing element 42 is within its own detection range, thereby simplifying the complex problem. The design of the detection component 4 is very clever and can reduce the cost of the detection component 4.

[0077] The first position detection sensor 41 may include but is not limited to a photoelectric sensor, and the sensing element 42 may include but is not limited to an iron sheet, which is not limited in this embodiment.

[0078] It should be noted that the above-mentioned first position detection sensor 41 is arranged on the positioning platform 1 and the sensing element 42 is arranged on the latch 22. This is only one possible setting method given in this embodiment. In another possible setting method, the first position detection sensor 41 can also be arranged on the latch 22, and the sensing element 42 can also be arranged on the positioning platform 1. This embodiment does not limit this.

[0079] In some embodiments, see Figure 4 and Figure 5 , Figure 5 yes Figure 4 The structural diagram of the positioning platform 1 along the negative viewing angle of the X-axis, the detection component 4 also includes a second position detection sensor 43, the second position detection sensor 43 is arranged on the positioning platform 1, and the latch 22 is in the opposite direction of the first direction ( Figure 5 When the sensing element 42 exits the communicating pin hole C in the negative direction of the center Z axis, the sensing element 42 is located within the detection range of the second position detection sensor 43.

[0080] By setting up the second position detection sensor 43, when the second position detection sensor 43 detects the sensing element 42, it can be determined that the latch 22 withdraws from the connected pin hole C, so that the withdrawal of the latch 22 from the connected pin hole C can also be detected, thereby making the detection of the fork assembly automatic pressing equipment 100 more accurate.

[0081] The second position detection sensor 43 may be similar to the first position detection sensor 41 . For details, reference may be made to the description of the first position detection sensor 41 in the above embodiment, which will not be described in detail in this embodiment.

[0082] In some embodiments, see Figure 5 A first dead stop 222 is provided on the latch pin 22, and a second dead stop 11 is provided on the positioning platform 1. The second dead stop 11 is located on the moving path of the first dead stop 222 along the first direction. When the latch pin 22 exits the connected pin hole C in the reverse direction of the first direction, the first dead stop 222 abuts against the second dead stop 11.

[0083] By arranging the second dead stop portion 11 on the moving path of the first dead stop portion 222 along the first direction, the latch 22 can move in the opposite direction ( Figure 5 When the plug 22 exits the connected pin hole C in the negative direction of the middle Z axis), the first dead stop portion 222 just abuts against the second dead stop portion 11, so that the excessive reverse movement of the plug 22 along the first direction can be avoided. At the same time, by making the first dead stop portion 222 just abut against the second dead stop portion 11 when the plug 22 exits the connected pin hole C in the reverse direction of the first direction, it can be ensured that the plug 22 can remain at the first end ( Figure 4 In this way, the plug pin 22 can block the corrugated pin D at the first end of the connecting pin hole C, so as to avoid the situation where the corrugated pin D is pushed out of the connecting pin hole C in the reverse direction of the first direction during the insertion of the cotter pin E, thereby ensuring that the corrugated pin D can always be located in the connecting pin hole C, thereby avoiding the abnormal extrusion of the corrugated pin D.

[0084] The first dead stop portion 222 and the second dead stop portion 11 may both be limit blocks or other possible structures, which are not limited in this embodiment.

[0085] In addition, the height of the first dead stop portion 222 and / or the second dead stop portion 11 along the first direction is adjustable. By making the height of the first dead stop portion 222 and / or the second dead stop portion 11 along the first direction adjustable, the automatic pressing equipment 100 of the fork assembly can be made more flexible, and better ensure that abnormal extrusion of the corrugated pin D is avoided.

[0086] In some embodiments, see Figure 3 The pressure head mechanism 3 includes: a pressure head driving member 31, a transverse movement assembly 32, a corrugated pin pressure head 33 and a cotter pin pressure head 34, wherein the corrugated pin pressure head 33 is used to place the corrugated pin D, and the cotter pin pressure head 34 is used to place the cotter pin E. The corrugated pin pressure head 33 and the cotter pin pressure head 34 are both arranged on the transverse movement assembly 32, and the transverse movement assembly 32 is used to drive the corrugated pin pressure head 33 and the cotter pin pressure head 34 to move to the pressure head driving member 31 respectively and connect with the pressure head driving member 31, the pressure head driving member 31 is used to drive the corrugated pin pressure head 33 to move in the reverse direction along the first direction so as to insert the corrugated pin D into the connecting pin hole C, or the pressure head driving member 31 is used to drive the cotter pin pressure head 34 to move in the reverse direction along the first direction so as to insert the cotter pin E into the through hole D1 of the corrugated pin D.

[0087] Since the corrugated pin ram 33 and the open pin ram 34 are both arranged in the transverse movement assembly 32, and since the transverse movement assembly 32 can drive the corrugated pin ram 33 and the open pin ram 34 to move to the ram driving member 31 respectively and connect with the ram driving member 31, and the ram driving member 31 can drive the corrugated pin ram 33 to move in the opposite direction of the first direction to insert the corrugated pin D into the connecting pin hole C, or drive the open pin ram 34 to move in the opposite direction of the first direction to insert the open pin E into the through hole D1 of the corrugated pin D. It can be seen that the same ram driving member 31 can not only drive the corrugated pin ram 33 to move in the opposite direction of the first direction to insert the corrugated pin D into the connecting pin hole C, but also drive the open pin ram 34 to move in the opposite direction of the first direction to insert the open pin E into the through hole D1 of the corrugated pin D. Therefore, the number of ram driving members 31 can be saved.

[0088] The pressure head driving member 31 may be a pneumatic cylinder or an electric cylinder, etc., which is not limited in this embodiment.

[0089] In addition, since the corrugated pin D can be inserted into the communicating pin hole C and the cotter pin E can be inserted into the through hole D1 of the corrugated pin D through the pressure head driving member 31, the labor intensity of personnel can be reduced.

[0090] In order to ensure that the angle of the opening of the cotter pin E in the communicating pin hole C meets the requirements when the cotter pin E is inserted into the communicating pin hole C, in some embodiments, see Figure 3 and Figure 6 , Figure 6 yes Figure 3 The partial structural diagram of the split pin press head 34 in FIG. Figure 6 The cotter pin press head 34 includes: a contour tooling 341, on which a protrusion 3411 matching the opening shape of the cotter pin E is provided. When the cotter pin E is placed on the contour tooling 341, the protrusion 3411 is accommodated in the opening of the cotter pin E.

[0091] Since the protrusion 3411 matching the opening shape of the cotter pin E is provided on the profiling tool 341, when the cotter pin E is placed on the profiling tool 341, the angle of the opening of the cotter pin E relative to the cotter pin press head 34 can be determined by simply placing the protrusion 3411 in the opening of the cotter pin E. On the basis that the angle of the opening of the cotter pin E relative to the cotter pin press head 34 is determined, when the cotter pin press head 34 presses the cotter pin E into the connected pin hole C, it can be ensured that the angle of the opening of the cotter pin E in the connected pin hole C meets the requirements.

[0092] In some embodiments, in order to accurately detect whether the cotter pin E is placed in place on the contoured tooling 341, in some embodiments, the automatic pressing equipment 100 of the fork assembly also includes: an in-place detection element (not shown in the figure), which is used to detect whether the protrusion 3411 is accommodated in the opening of the cotter pin E.

[0093] By setting up an in-place detection element, it is possible to accurately detect whether the protrusion 3411 is accommodated in the opening of the cotter pin E, thereby achieving the purpose of indirectly detecting whether the cotter pin E is placed in place on the contouring tooling 341.

[0094] The in-place detection element may be a through-beam sensor or other possible detection elements, and it only needs to detect whether the protrusion 3411 is accommodated in the opening of the cotter pin E. This embodiment does not limit the in-place detection element.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
