For the second bearing 50, the inner bore 11 of the second bearing 50 is sized to be similar to the outer diameter of the second stem 233, and the second bearing 50 can be sleeved on the second stem 233 and assembled into the drive shaft 10 under the urging of the first stem 232 during movement of the urging assembly 230. During the press fitting process of the parts, the second end of the transmission shaft 10 abuts against the pushing mechanism 300, and the pushing mechanism 300 provides reverse support for the transmission shaft 10 so as to ensure that the assembly position of the transmission shaft 10 is unchanged.

Illustratively, when the flip jaw 510 is reset and steps S300-S500 are repeated until all of the parts of the first end of the drive shaft 10 are assembled, at which point the parts of the second end of the drive shaft 10 may be assembled.

S600, reversing the first semi-finished product through the rotary table mechanism 100 so that the second end of the transmission shaft 10 faces the first press-fitting mechanism 200;

S700, transferring the part to be assembled at the second end of the transmission shaft 10 from the feeding mechanism 600 to the overturning clamping jaw 510 of the material overturning mechanism 500 through the material taking mechanism 700 according to a preset assembly sequence, and performing alignment and press fitting through the first press fitting mechanism 200 until the part assembly at the second end of the transmission shaft 10 is completed, so as to obtain a second semi-finished product;

Illustratively, the parts to be assembled at the second end of the transmission shaft 10 include the second bearing 50 and the end cover 60, and the operation principle of the assembly process is the same as that of the parts at the first end, which will not be described herein again, and when the assembly of the parts at the second end of the transmission shaft 10 is completed, a second semi-finished product is obtained.

And S900, inserting the copper pipe 70 from the first end of the transmission shaft 10 and extending out from the second end through the second press-fitting mechanism 400 so as to complete the assembly of the transmission structure.

Illustratively, the copper tube 70 is pre-placed on the second press-fitting mechanism 400 prior to start-up of assembly, and the copper tube 70 is inserted from the first end of the drive shaft 10 and extended from the second end by the second press-fitting mechanism 400, thereby completing assembly of the drive structure.

In this embodiment, the first press-fitting mechanism 200 can complete the assembly of the parts at the first end of the transmission shaft 10, the rotary stage mechanism 100 commutates the transmission shaft 10 so as to complete the assembly of the parts at the second end of the transmission shaft 10, and the second press-fitting mechanism 400 can complete the assembly of the copper pipe 70, wherein the feeding mechanism 600, the material taking mechanism 700 and the material turning mechanism 500 can realize the automatic feeding of the parts, and the overall assembly efficiency is high.

In step S200, assembly is started, and the transmission shaft 10 is compressed by the compressing mechanism 140, and then further includes: the transmission shaft 10 is pressed by the first press-fitting mechanism 200 to perform position calibration in cooperation with the pushing mechanism 300. This allows for pre-calibration of the position of the drive shaft 10 to reduce positional misalignment during assembly. Specifically, the first linear module 210 drives the pushing assembly 230 to abut against the driving shaft 10, wherein the second sleeve rod 233 is inserted into the driving shaft 10 and is cooperatively positioned in the inner hole 11 of the driving shaft 10, and the first sleeve rod 232 pushes the driving shaft 10 to a certain depth in the direction of the pushing mechanism 300 during the moving process, so as to ensure that the driving shaft 10 is pushed in place, thereby calibrating the position of the driving shaft 10.

As described above, referring to fig. 7, the pushing mechanism 300 includes a base 310, a first top block 320 and a second top block 330, the first top block 320 is disposed on the base 310, the second top block 330 is movably mounted on the base 310 and is located on a first side of the first top block 320, the second top block 330 is connected with a first lifting driving member, and in step S600, the first semi-finished product is reversed by rotating the stage mechanism 100, so that a second end of the transmission shaft 10 faces the first press-fitting mechanism 200, and the following steps are further included: the second jack 330 is driven to descend by the first elevating driving member to avoid the parts at the first end of the driving shaft 10.

It should be noted that, referring to fig. 1,2, 7 and 12, when the assembly of the parts at the first end of the transmission shaft 10 is completed, since the first end of the transmission shaft 10 is assembled with the end cap 60, the distance from the end of the end cap 60 to the center point of the transmission shaft 10 is greater than the distance from the second end of the transmission shaft 10 to the center point, after the reversing of the first semi-finished product, if the position of the pushing mechanism 300 is fixed, interference occurs between the first semi-finished product and the pushing mechanism 300, therefore, the second pushing block 330 can be lifted and lowered on the first side of the first pushing block 320, and reverse support can be provided for the transmission shaft 10 by the cooperation of the first pushing block 320 and the second pushing block 330 before the first semi-finished product is not reversed, and when the first semi-finished product needs to be reversed, the parts at the first end of the transmission shaft 10 can be avoided by the second pushing block 330 descending, so that reverse support is provided for the first semi-finished product by the first pushing block 320. It is contemplated that the first top block 320 may be provided with reinforcing ribs to increase structural strength, thereby providing sufficient reverse supporting force.

Referring to fig. 7, the pushing mechanism 300 further includes a supporting plate 340, the first top block 320 is provided with a avoidance hole 321, the supporting plate 340 is movably mounted on the base 310 and located on the second side of the first top block 320, the supporting plate 340 is connected with a second lifting driving member and can partially shield the avoidance hole 321, and in step S100, the copper tube 70 to be assembled is placed on the second press-fitting mechanism 400, including: the first end of the copper tube 70 to be assembled is placed on the second press mechanism 400 and the second end of the copper tube 70 is placed on the carrier 340 and partially within the clearance gap 321.

Illustratively, the avoidance space 321 on the first top block 320 may avoid the moving path of the copper tube 70 during assembly, and because the copper tube 70 has different heights, the bottom of the avoidance space 321 is slightly lower than the height of the copper tube 70 during assembly and movement, and because the copper tube 70 has a longer length, the second press-fitting mechanism 400 may support and position the first end of the copper tube 70, but also needs to support the second end of the copper tube 70 through the support plate 340, so that the axis of the copper tube 70 can be collinear with the axis of the transmission shaft 10, and the second end of the copper tube 70 is located in the avoidance space 321, so that the second end of the copper tube 70 is as close to the transmission shaft 10 as possible, so as to reduce the alignment deviation caused by the copper tube 70 during movement, and thus the copper tube 70 can be smoothly inserted into the transmission shaft 10.

Suitably, step 900 of inserting the copper tube 70 from the first end of the drive shaft 10 and extending from the second end by the second press-fit mechanism 400 to complete the assembly of the drive structure includes: inserting the copper tube 70 from the first end of the drive shaft 10 by the second press-fitting mechanism 400; when the copper pipe 70 is inserted to a predetermined depth, the support plate 340 is driven to descend by the second elevating driving unit to expose the avoidance space 321.

When the second end of the copper pipe 70 is inserted into the transmission shaft 10, the second end of the copper pipe 70 is connected with the second bearing 50 assembled in the first end of the transmission shaft 10, at this time, the correct installation position of the copper pipe 70 can be ensured, the bearing plate 340 is driven to descend by the second elevating driving member, and the avoidance spaces 321 can be exposed, so that the structural features with different heights on the copper pipe 70 can smoothly enter the avoidance spaces 321 to ensure the assembly in place.

It should be noted that, in step S600, the first semi-finished product is reversed by rotating the stage mechanism 100 so that the second end of the transmission shaft 10 faces the first press-fitting mechanism 200, and then further includes: the transmission shaft 10 is pressed by the first press-fitting mechanism 200 to perform position calibration in cooperation with the pushing mechanism 300. Because the distances between the left end and the right end of the first semi-finished product relative to the center point are different, the position calibration is carried out after the reversing of the first semi-finished product, and the position accuracy of assembly can be ensured.

As described above, the second press-fitting mechanism 400 includes the second linear module 410, the third linear module 420 and the bearing fixture 430, the third linear module 420 is mounted on the second linear module 410 and the moving direction is the same, the bearing fixture 430 is mounted on the third linear module 420, and the copper pipe 70 is inserted from the first end of the transmission shaft 10 and extends from the second end through the second press-fitting mechanism 400 in step S900 to complete the assembly of the transmission structure, including:

s910, driving the third linear module 420 and the bearing clamp 430 to move towards the direction of the transmission shaft 10 through the second linear module 410, so as to insert the copper pipe 70 to a preset depth from the first end of the transmission shaft 10 through the bearing clamp 430; s920, the third linear module 420 drives the bearing clamp 430 to move continuously, so that the copper pipe 70 extends out of the second end of the transmission shaft 10.

Illustratively, in some examples of application, for copper tubing 70 of sufficient strength, the second linear module 410 is driven to insert a depth into the drive shaft 10 quickly and then continue to move within the drive shaft 10 at a slower rate through the third linear module 420 to align with the internal bore 11 of the drive shaft 10 so as to protrude from the second end of the drive shaft 10.

In other examples of applications, the copper tube 70 is not strong enough, and slight rattling during insertion and movement of the drive shaft 10 causes misalignment between the end of the copper tube 70 and the second bearing 50 mounted on the second end of the drive shaft 10, thus requiring the cooperation of the first press-fitting mechanism 200 of the copper tube 70 to reduce the difficulty of press-fitting the copper tube 70. As described above, referring to fig. 2 and 6, the first press-fitting mechanism 200 includes a first linear module 210, a first sliding table 220 and a pressing assembly 230, the first sliding table 220 is installed on the first linear module 210, the pressing assembly 230 is installed on the first sliding table 220, the pressing assembly 230 includes a pressing cylinder 231, a first sleeve rod 232 and a second sleeve rod 233, the first sleeve rod 232 is movably sleeved in the pressing cylinder 231 and partially extends out of the end of the pressing cylinder 231, a first elastic member 234 is connected between the first sleeve rod 232 and the pressing cylinder 231, the second sleeve rod 233 is movably sleeved in the first sleeve rod 232 and partially extends out of the end of the second sleeve rod 233, and a second elastic member 235 is connected between the second sleeve rod 233 and the first sleeve rod 232, the step S920 is that the third linear module 420 drives the bearing fixture 430 to move continuously, so that the copper tube 70 extends out of the second end of the transmission shaft 10, and the first press-fitting mechanism includes:

S921, driving the jacking component 230 to abut against the second semi-finished product through the first linear module 210 so as to enable the second sleeve rod 233 to be inserted into the transmission shaft 10; s922, the third linear module 420 drives the bearing clamp 430 to move to a preset depth so as to enable the end of the copper pipe 70 to be abutted against the second sleeve rod 233; s923, the third linear module 420 drives the bearing clamp 430 to move continuously, so that the copper pipe 70 pushes against the second sleeve rod 233, and the copper pipe extends out of the transmission shaft 10 under the guidance of the second sleeve rod 233.

Illustratively, when the second loop bar 233 is inserted into the transmission shaft 10, the second loop bar 233 passes through the inner hole 11 of the transmission shaft 10, at this time, the second loop bar 233 is used as a guide bar, and when it is required to be described, the end portion of the second loop bar 233 is provided with a guide surface so that the copper pipe 70 abuts against the second loop bar 233, and when the copper pipe 70 abuts against the second loop bar 233, the copper pipe 70 is aligned under the guide of the second loop bar 233 so as to be aligned with the inner hole 11 of the transmission shaft 10, and then the copper pipe 70 continues to move and push against the second loop bar 233, since the second elastic member 235 providing the restoring elastic force to the second loop bar 233 is small, the second loop bar 233 exits the inner hole 11 of the transmission shaft 10 under the pushing action of the copper pipe 70, at this time, the copper pipe 70 smoothly passes through the inner hole 11 of the transmission shaft 10 and the second bearing 50 and the end cap 60 mounted under the guide of the second loop bar 233. In this way, even if the copper pipe 70 is inserted into the transmission shaft 10 and a small positional deviation occurs during the movement, it is possible to smoothly protrude from the second end of the transmission shaft 10 under the guide of the second socket rod 233. It should be noted that, before the copper pipe 70 is inserted, the first press-fitting mechanism 200 completes the assembly of the end cap 60 at the second end of the transmission shaft 10 and abuts against the end cap 60 installed at the second end of the transmission shaft 10, at this time, the first press-fitting mechanism 200 and the pushing mechanism 300 cooperate to clamp the second semi-finished product, and the second sleeve rod 233 penetrates the inner hole 11 of the transmission shaft 10, so as to facilitate the insertion of the copper pipe 70 and guide the copper pipe 70.

In step S923, the third linear module 420 drives the carrying fixture 430 to move continuously, so that the copper tube 70 pushes against the second sleeve rod 233 to extend out of the transmission shaft 10 under the guidance of the second sleeve rod 233, and then the method further includes:

S924, driving the top pressing assembly 230 to reset through the first linear module 210; s925, driving the bearing clamp 430 to move continuously through the third linear module 420, so as to insert the copper pipe 70 to a predetermined depth.

Illustratively, when the copper tube 70 is smoothly extended from the second end of the transmission shaft 10, the second sleeve rod 233 has reached the guiding purpose, and the pressing assembly 230 is driven to reset by the first linear module 210 at this time, so that the second sleeve rod 233 is retracted from the moving path of the copper tube 70, and the copper tube 70 is inserted to a predetermined depth under the driving of the third linear module 420, thereby completing the press-fitting of the copper tube 70. It should be noted that the lowest moving speed of the third linear module 420 is lower than that of the second linear module 410, so that the copper tube 70 can be slowly inserted into the transmission shaft 10 under the driving of the third linear module 420, so as to avoid the larger shaking amplitude of the copper tube 70 and the overlarge impact force when the copper tube 70 is abutted against the second loop bar 233.

Step S500, performing alignment and press-fitting on the part and the transmission shaft 10 by the first press-fitting mechanism 200, including:

S510, driving the pressing assembly 230 to move towards the transmission shaft 10 through the first linear module 210, so that the first sleeve rod 232 or the second sleeve rod 233 penetrates through the part; s520, loosening the part by turning over the clamping jaw 510 and resetting; and S530, during the moving process of the jacking assembly 230, the part and the transmission shaft 10 are aligned through the second sleeve rod 233, and the part is pressed through the jacking cylinder 231 or the first sleeve rod 232.

By way of example, taking press mounting of the first bearing 20 as an example, the first bearing 20 is placed in a space between the jacking component 230 and the transmission shaft 10 after the first bearing 20 is turned by 90 ° by the turning clamping jaw 510, the first linear module 210 drives the jacking component 230 to move towards the transmission shaft 10, during the moving process, the first sleeve rod 232 and the second sleeve rod 233 penetrate through the inner hole 11 of the first bearing 20, since the outer diameter of the first sleeve rod 232 is similar to the inner hole 11 of the first bearing 20, the first bearing 20 can be sleeved on the outer wall of the first sleeve rod 232, at this time, the turning clamping jaw 510 releases the first bearing 20 and resets, the first sleeve rod 232 drives the first bearing 20 to move together, during the moving process, the second sleeve rod 233 is inserted into the transmission shaft 10 and plays a role of alignment, the first sleeve rod 232 abuts against the transmission shaft 10 and stops under the blocking of the transmission shaft 10, and the jacking cylinder 231 continues to move, when the first sleeve rod 232 is compressed into the jacking cylinder 231, the jacking cylinder 231 presses the first bearing 20 towards the transmission shaft 10 until the first bearing 20 is pressed into place, and the first linear module 210 drives the jacking component 230 and the second sleeve rod 233 to separate from the transmission shaft 10. For the press fitting of the second bearing 50, the inner hole 11 of the second bearing 50 is sized to be similar to the outer diameter of the second sleeve rod 233, and the second bearing 50 can be sleeved on the second sleeve rod 233 and assembled into the transmission shaft 10 under the pressing action of the first sleeve rod 232 during the movement of the pressing assembly 230. During the press fitting process of the parts, the second end of the transmission shaft 10 abuts against the pushing mechanism 300, and the pushing mechanism 300 provides reverse support for the transmission shaft 10 so as to ensure that the assembly position of the transmission shaft 10 is unchanged. To facilitate the removal of the first and second stems 232, 233 after the press fitting of the parts is completed, the surfaces of the first and second stems 232, 233 are smoothed, such as by polishing or spraying a lubricating coating. For the press mounting of the end cover 60, the end cover 60 is clamped by the overturning clamping jaw 510 and the end cover 60 is placed in the space between the jacking component 230 and the transmission shaft 10, wherein the larger end of the end cover 60 faces the transmission shaft 10, the gap between the end cover 60 and the transmission shaft 10 is smaller, the jacking component 230 is close to and abutted against the end cover 60 under the driving of the first linear module 210, so that the second sleeve rod 233 passes through the end cover 60, at the moment, the end cover 60 is slightly loosened by the overturning clamping jaw 510, the end cover 60 can be abutted with the transmission shaft 10 under the pushing action of the jacking component 230, and then the end cover 60 is loosened by the overturning clamping jaw 510 and reset to avoid the moving path of the jacking component 230, so that the press mounting of the end cover 60 is completed.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
