Technical Field

[0002] During the assembly process of new energy vehicle drive motors, multiple shafts need to be installed into a single housing. Most existing shaft assembly and housing equipment uses robotic arms to grip the shafts and assemble multiple shafts into a shaft system on the robotic arm's grippers. Then, the robotic arm completes the housing installation. However, this method can only produce a single shaft system. The robotic arm has a complex structure and requires a robot with a large load capacity to assist it. With the production of hybrid vehicles, the number of shaft systems for new energy vehicle drive motors has increased. The assembly method that relies solely on robotic arm grippers not only suffers from slow speed, reducing the production efficiency of new energy vehicle drive motors, but also has the problem of low assembly accuracy.

[0032] After conveyor line 1 moves the conveyor tray to the heating frame 2, the robot arm 4 transfers the shafts on the conveyor tray to the assembly component 6. The heating component 5 heats the integrated bearing housing on the conveyor tray, while the assembly component 6 assembles multiple shafts into a shaft system.

[0033] like Figure 1-15 As shown, the conveying tray includes a rear cover tray and an integrated shell tray for intermittent conveying. The rear cover tray is used for loading the rear cover, intermediate shaft 103, differential shaft 104, and input shaft 105. The integrated shell tray is used for loading the integrated shell, generator output shaft 101, and generator input shaft 102. The output end of the robot 4 is equipped with a shaft system clamp 1 41 and a shaft system clamp 2 42.

When the rear cover tray arrives at the heating frame 2, the intermediate shaft 103, differential shaft 104 and input shaft 105 are transferred to the assembly assembly 6 by the three pneumatic grippers on the robot arm 4.

[0034] like Figure 1-15As shown, the assembly component 6 includes an assembly pallet 61, a pallet servo motor 62 for driving the assembly pallet 61 to move left and right on the assembly frame 3, and three moving splicing mechanisms 67 mounted on the assembly pallet 61: a first fixed rotation mechanism 63, a second fixed rotation mechanism 64, a first moving splicing mechanism 65, a second moving splicing mechanism 66, and a third moving splicing mechanism 67. The first fixed rotation mechanism 63 drives the generator output shaft 101 to rotate, the first moving splicing mechanism 65 drives the generator input shaft 102 to move and assemble with the generator output shaft 101, the second fixed rotation mechanism 64 drives the differential shaft 104 to rotate, the second moving splicing mechanism 66 drives the intermediate shaft 103 to move and assemble with the differential shaft 104, and the third moving splicing mechanism 67 drives the input shaft 101 to rotate. 05. The generator output shaft 101 is moved and assembled with the differential shaft 104. In this embodiment, the generator output shaft 101 is driven to rotate by the fixed rotation mechanism 1 63, and the generator input shaft 102 is moved and assembled with the generator output shaft 101 by the moving splicing mechanism 1 65, so that the generator output shaft 101 and the generator input shaft 102 are assembled into shaft system one. The differential shaft 104 is driven to rotate by the fixed rotation mechanism 2 64, the intermediate shaft 103 is moved and assembled with the differential shaft 104 by the moving splicing mechanism 2 66, and the input shaft 105 is moved and assembled with the differential shaft 104 by the moving splicing mechanism 3 67, so that the intermediate shaft 103, the differential shaft 104 and the input shaft 105 are assembled into shaft system two. The assembly pallet 61 is moved left and right by the pallet servo motor 62, so that the assembly pallet 61 extends or retracts from the assembly frame 3.

[0035] like Figure 1-15As shown, both the fixed rotation mechanism 63 and the fixed rotation mechanism 64 include a rotating frame 631 fixed on the assembly pallet 61, a rotating motor 632 and a rotating cylinder 633 fixed on the assembly pallet 61. The output shaft of the rotating motor 632 extends vertically upward into the rotating frame 631 and drives a rotating drive gear 6321. A rotating sleeve 634 is rotatably connected to the rotating frame 631. A push rod 635 is slidably connected up and down inside the rotating sleeve 634. A driven gear 6341 is fixed on the rotating sleeve 634. The rotating drive gear 6321... Engaging with the driven gear 6341, the piston rod head of the self-rotating cylinder 633 extends upward to drive the bottom end of the push rod 635. A positioning head 6342 is provided at the top of the rotating sleeve 634, and a conical head 636 is provided on the positioning head 6342. The top end of the push rod 635 passes through the conical head 636 and is fitted with a fixing sleeve 637. An elastic sleeve 638 is fitted on the push rod 635, and multiple tension grooves 6381 extending through the bottom end of the elastic sleeve 638 are provided on the elastic sleeve 638. The bottom end of the elastic sleeve 638 abuts against an inclined surface. The tapered head 636 has a fixed sleeve 637 whose outer diameter is larger than that of the elastic sleeve 638. In this embodiment, shaft gears and bearings are respectively provided on the generator output shaft 101, generator input shaft 102, intermediate shaft 103, differential shaft 104, and input shaft 105, and each of these shafts has an axially penetrating shaft hole. In use, the robot arm 4 inserts the shaft hole at the bottom end of the generator output shaft 101 or the bottom end of the differential shaft 104 into the tapered head 636 and presses it down, causing it to rotate. The piston rod head of cylinder 633 retracts downwards, and the piston rod head drives the fixed sleeve 637 to move downwards via the push rod 635. During the downward movement of the fixed sleeve 637 pressing against the elastic sleeve 638, the elastic sleeve 638 abuts against the conical head 636 through the abutting inclined surface, and the tension groove 6381 expands. The increased outer diameter of the elastic sleeve 638 tightens the shaft hole of the generator output shaft 101 or the differential shaft 104. Through the self-rotating motor 632, the self-rotating driving gear 6321 and the driven gear 6341, the rotating sleeve 634 is driven to rotate, causing the generator output shaft 101 or the differential shaft 104 on the rotating sleeve 634 to rotate.

[0036] like Figure 1-15As shown, the first mobile splicing mechanism 65 includes a mobile positioning seat 651, a Y-axis servo motor 652 for driving the mobile positioning seat 651 to move forward and backward, a Y-axis frame 653 for mounting the Y-axis servo motor 652, and an X-axis servo motor 654 for driving the Y-axis frame 653 to move left and right. The X-axis servo motor 654 is mounted on the assembly tray 61. The second mobile splicing mechanism 66 includes a second mobile positioning seat 661, an X-axis servo motor 662 for driving the mobile positioning seat 661 to move left and right, and an X-axis frame for mounting the X-axis servo motor 662. The X-axis frame 663 is used to drive the X-axis frame 663 to move back and forth, and the Y-axis servo motor 664 is mounted on the assembly pallet 61; the moving assembly mechanism 67 includes a moving positioning seat 671, a Y-axis servo motor 672 used to drive the moving positioning seat 671 to move back and forth, a Y-axis frame 673 used to mount the Y-axis servo motor 652, and an X-axis servo motor 674 used to drive the Y-axis frame 673 to move left and right, and the X-axis servo motor 674 is mounted on the assembly pallet 61; the moving positioning seat 651, the moving positioning seat 662, and the moving positioning seat 671 are all mounted on the assembly pallet 61. Each of the three moving positioning seats 671 includes a positioning bracket 6711, and a cylindrical seat 6712 rotatably mounted on the positioning bracket 6711 via a rotating bearing. The top of the cylindrical seat 6712 is provided with a blind hole. In this embodiment, during use, the bottom ends of the power generation input shaft 102, intermediate shaft 103, and input shaft 105 are respectively inserted into the corresponding blind holes by the robot arm 4, thereby positioning the power generation input shaft 102, intermediate shaft 103, and input shaft 105. The moving positioning seat 651 is moved back and forth by the Y-axis servo motor 652, and the Y-axis bracket 653 is moved left and right by the X-axis servo motor 654, so that the power generation input shaft on the moving positioning seat 651... 102 approaches the rotating generator output shaft 101 until the shaft gear on the generator input shaft 102 meshes with the shaft gear on the generator output shaft 101. The generator input shaft 102 rotates with the generator output shaft 101, completing the assembly of shaft system one. The X-axis servo motor 2 662 drives the moving positioning seat 2 661 to move left and right, and the Y-axis servo motor drives the X-axis frame 1 663 to move back and forth, so that the intermediate shaft 103 on the moving positioning seat 2 661 approaches the rotating differential shaft 104 until the shaft gear on the intermediate shaft 103 meshes with the shaft gear on the differential shaft 104. The intermediate shaft 103 rotates with the differential shaft 104, completing the assembly of intermediate shaft 103.The Y-axis servo motor 3672 drives the moving positioning seat 3671 to move back and forth, while the X-axis servo motor 3674 drives the Y-axis frame 2 673 to move left and right. This causes the input shaft 105 on the moving positioning seat 3671 to approach the rotating differential shaft 104, until the shaft gear on the input shaft 105 meshes with the shaft gear on the differential shaft 104. The input shaft 105 then rotates with the differential shaft 104, completing the assembly of the second shaft system.

[0037] like Figure 1-15 As shown, the second movable splicing mechanism 66 further includes a conical pressure head 665 disposed directly above the blind hole of the second movable positioning seat 661, a pressure frame 666 for mounting the conical pressure head 665, a splicing lifting cylinder 667 for driving the pressure frame 666 to rise or fall, a Y-axis frame 668 for mounting the splicing lifting cylinder 667, and a transverse cylinder 669 for driving the Y-axis frame 668 to move back and forth. The conical pressure head 665 rotates. Mounted on the pressure frame 666, the transverse cylinder 669 is fixed on the X-axis frame 663. In this embodiment, since the shaft gear on the intermediate shaft 103 is located near the top of the intermediate shaft 103, the transverse cylinder 669 drives the Y-axis frame 668 to move backward, and the splicing lifting cylinder 667 drives the pressure frame 666 to move the conical pressure head 665 downward. This allows the intermediate shaft 103 to be rotatably pressed between the conical pressure head 665 and the movable positioning seat 661, preventing the intermediate shaft 103 from shifting during the assembly process.

The longitudinal linear motors 713 and 716 are fixedly mounted on the assembly frame 3. Two pneumatic grippers 79 are provided on the clamping seat 79. 1. Two pneumatic grippers 791 are positioned opposite the assembled power generation input shaft 102 and power generation output shaft 101. Three pneumatic grippers 7101 are provided on the clamp seat 710. The pneumatic grippers 7101 are positioned opposite the assembled intermediate shaft 103, input shaft 105 and differential shaft 104. In this embodiment, when the heated integrated shell tray is moved to the top of the lifting plate 71, the lifting cylinder 72 drives the lifting plate 71 to rise and support the integrated shell tray. The slider cylinder 77 drives the lifting slider 76 to slide into the bottom of the lifting plate 71. The first lifting slope and the second lifting slope abut against each other to prevent the conveyor line 1 from being damaged during the packing process.The assembled generator input shaft 102 and generator output shaft 101 are gripped by two pneumatic grippers 791 on clamp seat 1 79. The pneumatic grippers 791 and shaft system 1 are moved to the top of the integrated housing by the inlet lifting linear motor 711, inlet lateral linear motor 712, and inlet longitudinal linear motor 713. Simultaneously, the assembled intermediate shaft 103, input shaft 105, and differential shaft 104 are gripped by three pneumatic grippers 7101 on clamp seat 2 710. The pneumatic grippers 7101 and shaft system 2 are moved to the top of the integrated housing by the inlet lifting linear motor 714, inlet lateral linear motor 715, and inlet longitudinal linear motor 716. Finally, shaft system 1 and shaft system 2 are pressed into the integrated housing by the inlet lifting linear motor 711 and inlet lifting linear motor 714.

[0039] like Figure 1-15 As shown, the heating assembly 5 includes a lifting plate 51 disposed below the conveyor line 1, a lifting cylinder 52 for driving the lifting plate 51 to rise or fall, and a lifting mounting plate 53 for mounting the lifting cylinder 52 on the heating frame 2.

Multiple electric heating tubes 56 are respectively disposed at the bottom of the heating seat 1 54 and heating seat 2 55. Each set of heating displacement mechanisms includes a front-to-back linear motor 571 fixed on the heating frame 2. The output end of the front-to-back linear motor 571 is connected to a left-to-right linear motor 572, and the output end of the left-to-right linear motor 572 is connected to a heating lifting linear motor. The output of the heating and lifting linear motor 573 is connected to either heating seat 1 54 or heating seat 2 55. In this embodiment, when the conveying tray is moved directly above the lifting plate 51, the conveying line 1 stops conveying, and the robot arm 4 transfers the shaft on the conveying tray to the assembly component 6. When the integrated shell tray is moved directly above the lifting plate 51, the lifting cylinder 52 drives the lifting plate 51 to rise, supporting the integrated shell tray on the conveying line 1. The positions of heating seat 1 54 and heating seat 2 55 are adjusted by the heating front and rear linear motors 571, the heating left and right linear motors 572, and the heating and lifting linear motor 573, so that the electric heating tube 56 extends from top to bottom into the bearing chamber on the integrated shell to heat the bearing chamber. After heating is completed, heating seat 1 54 and heating seat 2 55 rise, the lifting plate 51 descends, and the conveying line 1 moves the heated integrated shell to the box assembly 7.
