[0057] like Figure 1 and Figure 2As shown, the embodiment of the present application provides a gearbox shaft loading machine 1, which mainly includes a machine base circulation transmission mechanism 100, a spring pre-installation mechanism 200, a first bearing pre-installation mechanism 300, an outer rubber shell pre-installation mechanism 400, a second bearing pre-installation mechanism 500, an output shaft pre-installation mechanism 600, an output shaft pressing mechanism 700, a detection mechanism 800 and a discharging robot 900. Among them, the machine base circulation transmission mechanism 100 is mainly used to send the machine base assembly 2 from the initial station 11 to the spring pre-installation station 12, the first bearing pre-installation station 13, the outer rubber shell pre-installation station 14, the second bearing pre-installation station 15, the output shaft pre-installation station 16, the output shaft pressing station 17, the detection station 18 and the discharging station 19 in sequence, and then send the machine base assembly 2 back to the initial station 11 again. The retaining spring pre-installation mechanism 200 may be specifically located at the retaining spring pre-installation station 12, and is mainly used to pre-assemble the retaining spring into the first machine seat 21 of the machine seat assembly 2 at the retaining spring pre-installation station 12. The first bearing pre-installation mechanism 300 may be specifically located at the first bearing pre-installation station 13, and is mainly used to pre-assemble the first bearing into the second machine seat 22 of the machine seat assembly 2 at the first bearing pre-installation station 13. The outer rubber shell pre-installation mechanism 400 may be specifically located at the outer rubber shell pre-installation station 14, and is mainly used to pre-assemble the outer rubber shell into the second machine seat 22 at the outer rubber shell pre-installation station 14, so that the outer rubber shell and the first bearing are assembled together. The second bearing pre-installation mechanism 500 may be specifically located at the second bearing pre-installation station 15, and is mainly used to pre-assemble the second bearing into the first machine seat 21 at the second bearing pre-installation station 15, so that the second bearing and the retaining spring are assembled together. The output shaft pre-installation mechanism 600 can be specifically located at the output shaft pre-installation station 16, and is mainly used to pre-assemble the output shaft into the first machine base 21 on the output shaft pre-installation station 16, so that the output shaft, the second bearing and the retaining spring are assembled together to obtain a semi-finished product. The output shaft pressing mechanism 700 can be specifically located at the output shaft pressing station 17, and is mainly used to press and assemble the semi-finished product in the first machine base 21 on the output shaft pressing station 17 into the second machine base 22, so that the outer rubber shell, the first bearing, the output shaft, the second bearing and the retaining spring are assembled together to obtain a finished product.

[0058] It is understandable that the gearbox shaft insertion machine 1 of the embodiment of the present application is mainly used in the assembly process of the gearbox to realize the assembly operation between the outer rubber shell, the output shaft, the bearing and the retaining spring of the gearbox, that is, the output shaft, the two bearings and the retaining spring are respectively assembled in the outer rubber shell to complete the shaft insertion process in the assembly process of the gearbox. In order to improve the working efficiency of the entire gearbox shaft insertion process, the machine base assembly 2 adopts a double machine base structure, that is, it includes a first machine base 21 and a second machine base 22. The height of the first machine base 21 will be higher than the height of the second machine base 22 to meet the actual installation scene requirements.

[0059] Thus, in the embodiment of the present application, in the entire gearbox shaft insertion process, whether it is the assembly of the retaining ring, or the assembly of the first bearing, the outer rubber shell, the second bearing and the output shaft, it can be automatically completed by the corresponding mechanism to ensure its assembly efficiency. At the same time, after its assembly is completed, a corresponding detection mechanism 800 is also provided to perform assembly quality inspection on the assembled finished product, so that the discharging manipulator 900 can sort and discharge the corresponding finished product according to the result of the assembly quality inspection, thereby effectively ensuring the assembly quality of the finished product. In addition, its machine base circulation transmission mechanism 100 can realize the rapid recycling of the machine base assembly 2, so as to save the use cost of the machine base assembly 2 and further ensure its assembly efficiency. It can be seen that the present technical solution can automatically complete the assembly operation between the outer rubber shell, the output shaft, the bearing and the retaining ring in the gearbox assembly, and can ensure the assembly efficiency and assembly quality.

[0060] In some examples, such as Figure 1 and Figure 2As shown, the machine base circulation transmission mechanism 100 may specifically include a first machine base longitudinal feeding channel 110, a machine base transverse feeding channel 120, a second machine base longitudinal feeding channel 130, and a machine base transverse return feeding belt 140. Among them, the first machine base longitudinal feeding channel 110 may specifically include a first channel body 111 arranged longitudinally and a first longitudinal pushing mechanism 112 driving the machine base assembly 2 to move on the first channel body 111 along the extension direction of the first channel body 111. The machine base transverse feeding channel 120 may specifically include a second channel body 121 disposed transversely and a transverse pushing mechanism 122 driving the machine base assembly 2 to move on the second channel body 121 along the extension direction of the second channel body 121, and the second channel body 121 is sequentially provided with an initial station 11, a retaining spring pre-installation station 12, a first bearing pre-installation station 13, an outer rubber shell pre-installation station 14, a second bearing pre-installation station 15, an output shaft pre-installation station 16, an output shaft pressing station 17, a detection station 18 and a discharge station 19 along its extension direction. The second machine base longitudinal feeding channel 130 may specifically include a third channel body 131 disposed longitudinally and a second longitudinal pushing mechanism 132 driving the machine base assembly 2 to move on the third channel body 131 along the extension direction of the third channel body 131. The machine base transversely shifted return belt 140 may specifically include a return belt 141 disposed transversely and a belt drive motor 144 driving the machine base assembly 2 to move on the return belt 141 along the extension direction of the return belt 141. The first channel body 111, the second channel body 112, the third channel body 113 and the return belt 114 are sequentially arranged end to end. In this way, through the above-mentioned structural arrangement, under the sequential cooperation of the first machine base longitudinal feeding channel 110, the machine base transverse feeding channel 120, the second machine base longitudinal feeding channel 130 and the machine base transverse return feeding belt 140, the machine base assembly 2 can be well sent from the initial station 11 to the retaining ring pre-installation station 12, the first bearing pre-installation station 13, the outer rubber shell pre-installation station 14, the second bearing pre-installation station 15, the output shaft pre-installation station 16, the output shaft pressing station 17, the inspection station 18 and the discharge station 19 in sequence, and then sent back to the initial station 11, so as to realize the circulation flow of the machine base assembly 2 in these stations.

[0061] It can be understood that the structures of the first longitudinal pushing mechanism 112, the transverse pushing mechanism 122 and the second longitudinal pushing mechanism 132 in this example are basically the same, and are mainly composed of a push plate and a push plate cylinder that drives the push plate to move linearly. In this example, the feeding direction of the first material channel body 111 and the feeding direction of the third material channel body 113 are set in opposite directions, and the feeding reverse direction of the second material channel body 112 and the return belt 114 are also set in opposite directions.

[0062] In some examples, such as Figure 1 and Figure 2As shown, the machine base circulation transmission mechanism 100 specifically further includes a plurality of machine base positioning components 150, and the plurality of machine base positioning components 150 correspond one by one to the spring pre-installation station 12, the first bearing pre-installation station 13, the outer rubber shell pre-installation station 14, the second bearing pre-installation station 15, the output shaft pre-installation station 16, and the output shaft pressing station 17. In this way, through the above-mentioned structural setting, when the machine base component 2 is respectively transmitted to the spring pre-installation station 12, the first bearing pre-installation station 13, the outer rubber shell pre-installation station 14, the second bearing pre-installation station 15, the output shaft pre-installation station 16, and the output shaft pressing station 17 through the machine base circulation transmission mechanism 100, it can be positioned at the corresponding station through the corresponding machine base positioning component 150. Furthermore, the machine base positioning assembly 150 may specifically include a positioning member (not shown) and a positioning member lifting cylinder (not shown) for driving the positioning member to rise and fall. The positioning member is located at the corresponding workstation, and is driven by the positioning member lifting cylinder to extend from the bottom of the second material channel body 121 to position the machine base assembly 2 on the second material channel body 121 at the corresponding workstation. In this way, the above-mentioned structural arrangement allows the machine base assembly 2 to be well positioned at the corresponding workstation through the positioning member when it is transferred to the corresponding workstation.

[0063] It can be understood that, in order to facilitate the machine base assembly 2 to be sent to the corresponding workstation (such as the retaining spring pre-installation station 12, the first bearing pre-installation station 13, the outer rubber shell pre-installation station 14, the second bearing pre-installation station 15, the output shaft pre-installation station 16 and the output shaft pressing station 17), the gear box shaft entry machine 1 can promptly start the corresponding machine base positioning assembly 150 at the corresponding workstation to position it at the corresponding workstation. The gear box shaft entry machine 1 can also be provided with an in-place detection sensor (not shown) at each corresponding workstation (such as the retaining spring pre-installation station 12, the first bearing pre-installation station 13, the outer rubber shell pre-installation station 14, the second bearing pre-installation station 15, the output shaft pre-installation station 16 and the output shaft pressing station 17) to accurately detect whether the machine base assembly 2 has been sent to the corresponding workstation through the corresponding in-place detection sensor.

[0064] In some examples, such as Figure 1 and Figure 3As shown, the circlip pre-installation mechanism 200 may specifically include a circlip vibration plate feeding assembly 210, a circlip lower material distribution assembly 220, a circlip transverse delivery assembly 230, a circlip supporting assembly 240, and a circlip removal assembly 250. Among them, the circlip vibration plate feeding assembly 210 may specifically include a circlip feeding channel 211 and a circlip vibration plate 212 that drives the circlip to vibrate and transmit on the circlip feeding channel 211. The circlip lower material distribution assembly 220 may specifically include a guide slope 221 that docks with the end of the circlip feeding channel 211 and a circlip lower material distribution cylinder 222 that drives the circlip to rise upward along the guide slope 221, so that the circlip is in a horizontal position under the guidance of the guide slope 221. The circlip transverse conveying assembly 230 may specifically include a circlip push block 231 docked with the guide slope 221 and a circlip transverse movement cylinder 232 driving the circlip push block 231 to move transversely, so that the circlip in a horizontal position is pushed to the circlip waiting position under the transverse movement of the circlip push block 231. The circlip supporting assembly 240 may specifically include a circlip supporting block 241 with a circlip waiting position and a circlip supporting cylinder 242 driving the circlip supporting block 241 to rise and fall. The circlip removal assembly 250 may specifically include a circlip removal head 251, a circlip lifting cylinder 252 driving the circlip removal head 251 to rise and fall, and a circlip translation cylinder 253 driving the circlip removal head 251 to translate above the circlip waiting position and above the circlip pre-installation station 12. In this way, through the above-mentioned structural setting, the spring loading operation and the spring pre-assembly operation of automatically pre-assembling the spring into the first machine base 21 of the machine base assembly 2 on the spring pre-assembly station 12 can be automatically realized under the sequential cooperation of the spring vibration plate loading assembly 210, the spring lower distribution assembly 220, the spring horizontal delivery assembly 230, the spring supporting assembly 240 and the spring removal assembly 250.

[0065] It can be understood that the retaining spring removal head 251 in this example can be specifically moved downward continuously by the retaining spring lifting cylinder 252 above, so that the material removal sleeve of the retaining spring removal head 251 is expanded and expanded, so as to achieve the purpose of removing the retaining spring.

[0066] In some examples, such as Figure 1 and Figure 4As shown, the first bearing pre-installation mechanism 300 may specifically include a bearing loading column 310, a bearing material distribution assembly 320, and a bearing removal assembly 330. Among them, the bearing loading column 310 is used to stack and place the bearing string in the vertical direction. The bearing feeding assembly may specifically include a bearing feeding channel 321 and a bearing feeding cylinder 322 that drives the bearing to move on the bearing feeding channel 321, and the bearing loading column 310 is vertically arranged at the beginning of the bearing feeding channel 321. The bearing removal assembly 330 may specifically include a bearing removal head 331, a bearing lifting cylinder 332 that drives the bearing removal head 331 to rise and fall, and a bearing translation cylinder 333 that drives the bearing removal head 331 above the end of the bearing feeding channel 321 and the corresponding first bearing pre-installation station 13. Similarly, the structure of the second bearing pre-installation mechanism 500 is basically the same as that of the first bearing pre-installation mechanism 300, and will not be repeated here. It should be noted that the bearing translation cylinder of the second bearing pre-installation mechanism 500 is used to drive the corresponding bearing removal head to translate above the end of the corresponding bearing feeding channel and above the corresponding second bearing pre-installation station 15. The bearing removal head 331 can specifically perform the corresponding bearing removal and placement operation by taking the inner hole of the bearing. In this way, through the above-mentioned structural setting, the first bearing or the second bearing loading operation can be automatically realized under the sequential cooperation of the bearing loading column 310, the bearing distribution component 320 and the bearing removal component 330, and the first bearing can be pre-assembled into the second machine seat 22 of the machine seat assembly 2 on the first bearing pre-installation station 13 or the second bearing can be pre-assembled into the first machine seat 21 on the second bearing pre-installation station 15, so that the second bearing and the retaining spring are assembled together.

[0067] In some examples, such as Figure 1 and Figure 5As shown, the outer rubber shell pre-installation mechanism 400 may specifically include an outer rubber shell vibration plate loading component 410, an outer rubber shell feeding component 420, and an outer rubber shell loading component 430. Among them, the outer rubber shell vibration plate loading component 410 may specifically include an outer rubber shell loading channel 411 and an outer rubber shell vibration plate 412 that drives the outer rubber shell to vibrate and transmit on the outer rubber shell loading channel 411. The outer rubber shell feeding component 420 may specifically include an outer rubber shell feeding channel 421 and an outer rubber shell feeding cylinder 422 that drives the outer rubber shell to move on the outer rubber shell feeding channel 421, and the end of the outer rubber shell loading channel 411 is docked with the beginning of the outer rubber shell feeding channel 421. The outer rubber shell taking and installing component 430 may specifically include an outer rubber shell taking and installing head 431, an outer rubber shell lifting cylinder 432 for driving the outer rubber shell taking and installing head 431 to lift and lower, and an outer rubber shell translation cylinder 433 for driving the outer rubber shell taking and installing head 431 to translate above the end of the feeding channel on the outer rubber shell and above the outer rubber shell pre-installation station 14. In this way, through the above-mentioned structural setting, the outer rubber shell feeding operation can be automatically realized under the sequential cooperation of the outer rubber shell vibration plate feeding component 410, the outer rubber shell feeding component 420 and the outer rubber shell taking and installing component 430, and the outer rubber shell can be automatically pre-assembled into the second machine base 22 on the outer rubber shell pre-installation station 14, so that the outer rubber shell and the first bearing are assembled together.

[0068] It can be understood that the outer plastic shell taking and placing head 431 in this example can specifically clamp the outer plastic shell with the assistance of an air gripper cylinder to complete the taking and placing operation of the corresponding outer plastic shell.

[0069] In some examples, such as Figure 1 and Figure 6As shown, the output shaft pre-installation mechanism 600 may specifically include an output shaft push plate type loading assembly 610, an output shaft material dividing assembly 620, and an output shaft taking assembly 630. Among them, the output shaft push plate type loading assembly 610 may specifically include an output shaft material storage bin 611, an output shaft material feeding channel 612, a push plate type loading power mechanism 613 that simultaneously transfers multiple output shafts in the output shaft material storage bin 611 to the beginning of the output shaft material feeding channel 612, and an output shaft feeding power mechanism 614 that drives the output shaft to be transferred on the output shaft material feeding channel 612. The output shaft material distribution component 620 may specifically include an output shaft clamping block 621 having an output shaft clamping slot (not shown in the figure) and an output shaft material distribution cylinder 622 that drives the output shaft clamping block 621 to extend and retract, so that the output shaft clamping slot can be switched back and forth between the docking position docking with the end of the output shaft feeding channel 611 and the output shaft waiting position under the extension and retraction of the output shaft clamping block 621. The output shaft installation component 630 may specifically include an output shaft installation head 631, an output shaft lifting cylinder 632 that drives the output shaft installation head 631 to rise and fall, and an output shaft translation cylinder 633 that drives the output shaft installation head 631 to translate above the output shaft waiting position and above the output shaft pre-installation station 16. In this way, through the above-mentioned structural setting, the output shaft loading operation can be automatically realized with the sequential cooperation of the output shaft push plate loading assembly 610, the output shaft dividing assembly 620 and the output shaft removal assembly 630, and the output shaft can be automatically pre-assembled into the first machine base 21 on the output shaft pre-assembly station 16, so that the output shaft, the second bearing and the retaining spring are assembled together to obtain a semi-finished product.

[0070] It can be understood that the output shaft stacking bin 611 in this example is mainly used to stack multiple output shafts to be loaded. One side of the output shaft stacking bin 611 can be specifically connected to the starting end of the output shaft loading channel 612. At the same time, the push plate type loading power mechanism 613 includes multiple liftable push plates (not shown in the figure), the top ends of the multiple liftable push plates are arranged in a stepped manner, and the closer the top end of the liftable push plate is to the starting end of the output shaft loading channel 612, the higher its height is, so that the multiple output shafts are simultaneously transferred to the starting end of the output shaft loading channel 612 through the pushing effect formed by the lifting movement of the multiple liftable push plates. And in the process of transmission and transfer of the output shaft feeding power mechanism 614, since the two ends of the output shaft have a large difference in size and are top-heavy, the output shaft can be driven by the output shaft feeding power mechanism 614 to transmit on the output shaft material channel 611 to determine the direction, so that the output shaft is vertically arranged in a uniform direction on the output shaft material channel 611.

[0071] In some examples, such as Figure 1 and Figure 7As shown, the output shaft pressing mechanism 700 includes a semi-finished product removal assembly 710 and a pressing assembly 720, wherein the semi-finished product removal assembly 710 includes a semi-finished product removal head 711, a semi-finished product lifting cylinder 930712 for driving the semi-finished product removal head 711 to rise and fall, and a semi-finished product translation cylinder 940713 for driving the semi-finished product removal head 711 to translate above the first machine seat 21 on the output shaft pressing station 17 and above the second machine seat 22 on the output shaft pressing station 17. The pressing assembly 720 includes a semi-finished product pressing head 810721 located above the second machine seat 22 on the output shaft pressing station 17 and a first pressing cylinder 722 for driving the semi-finished product pressing head 810721 to rise and fall. In this way, through the above-mentioned structural setting, the semi-finished product in the first machine base 21 on the output shaft press-in station 17 can be automatically pressed and assembled into the second machine base 22 under the sequential cooperation of the semi-finished product removal assembly 710 and the press-in assembly 720, so that the outer rubber shell, the first bearing, the output shaft, the second bearing and the retaining spring are assembled together to obtain the finished product.

[0072] In some examples, such as Figure 1 and Figure 8 As shown, the detection mechanism 800 includes a finished product pressing head 810, a second pressing cylinder 820 for driving the finished product pressing head 810 to rise and fall, a spring probe 830, and a sensor 840 for detecting the compression amount of the spring probe 830. The finished product pressing head 810 is located above the second machine base 22 on the detection station 18, and the spring probe 830 is located below the second machine base 22 on the detection station 18. In this way, the finished product can be pressed down by the finished product pressing head 810, so that the finished product abuts against the spring probe 830 to cause the spring probe 830 to be compressed, and the sensor 840 detects the compression amount of the spring probe 830 to automatically detect the assembly quality of the finished product, that is, if the finished product is missing, the spring probe 830 will not be compressed or the compression amount is not large, so that the sensor 840 cannot sense it, thereby achieving the purpose of quality detection.

[0073] In some examples, such as Figure 1 and Fig. 9 As shown, the discharging manipulator 900 includes a finished product clamp 910, a flip motor 920 driving the finished product clamp 910 to flip 180 degrees, a finished product lifting cylinder 930 driving the finished product clamp 910 to lift and lower, and a finished product translation cylinder 940 driving the finished product clamp 910 to translate above the discharging station 19 and above at least two unloading stations. In this way, through the above-mentioned structural setting, the finished product clamp 910, the flip motor 920, the finished product lifting cylinder 930 and the finished product translation cylinder 940 can be respectively coordinated to automatically realize the sorting and discharging operation of the finished products in the second machine base 22 located on the discharging station 19 according to the results of the assembly quality inspection.
