[0036] Please refer to Figure 1 and Figure 2 , this embodiment discloses a stator oil ring press-fitting device, including a conveying line body 100, a clamping and press-fitting mechanism 200, an oil ring feeding mechanism 300, an oil ring transfer mechanism 400, and an oil ring picking mechanism 500. The length of the conveying line body 100 is arranged along a first direction, and the first direction is indicated as the left-right direction. The conveying line body 100 is installed with a jacking and positioning mechanism 110. The clamping and press-fitting mechanism 200 is installed above the jacking and positioning mechanism 110. The oil ring feeding mechanism 300 is installed adjacent to the conveying line body 100. The oil ring feeding mechanism has a plurality of bins arranged along the first direction. The oil ring transfer mechanism 400 has a first working position and a second working position. The first working position of the oil ring transfer mechanism 400 is located below the clamping and press-fitting mechanism 200. The second working position of the oil ring transfer mechanism 400 is located adjacent to the oil ring feeding mechanism 300. The oil ring picking mechanism 500 is installed between the oil ring feeding mechanism 300 and the oil ring transfer mechanism 400. The working range of the oil ring picking mechanism 500 covers the oil ring transfer mechanism 400 and a plurality of bins.
[0037] When in use, oil ring materials are pre-placed in the silo of the oil ring feeding mechanism 300. There are multiple silos, which can meet the processing and feeding needs for a longer period of time, avoid frequent loading, and help reduce manual labor intensity. The oil ring picking mechanism 500 takes the oil ring materials from the corresponding silo and transfers them to the oil ring transferring mechanism 400. The oil ring transferring mechanism 400 transfers the oil ring to the bottom of the clamping and pressing mechanism 200, and the oil ring material is clamped by the clamping and pressing mechanism 200 for subsequent oil ring pressing. In this way, automatic loading and pressing of the oil ring material can be achieved, which is beneficial to improving the degree of automation and reducing manual labor intensity. The conveyor line body 100 is used to receive the pallet carrier from the previous process. The middle shell material to be assembled can be placed on the pallet carrier, or the middle shell material to be assembled can be placed on an empty pallet carrier by a robot. The pallet carrier is lifted by the lifting and positioning mechanism 110 to separate the pallet carrier from the conveyor line body 100, so as to cooperate with the clamping and pressing mechanism 200 to press the oil ring material.
[0038] Please refer to Figure 1 , the clamping and pressing mechanism 200 includes a lifting bracket 210, a pressing driving member 220, an inner support fixture 230 and a pressure ring 240. The lifting bracket 210 is connected to the pressing driving member 220. The inner support fixture 230 and the pressure ring 240 are both installed at the bottom of the lifting bracket 210, and the inner support fixture 230 is located on the inner side of the pressure ring 240. When the oil ring transfer mechanism 400 transfers the oil ring to the bottom of the clamping and pressing mechanism 200, the pressing driving member 220 drives the lifting bracket 210 to descend, thereby driving the inner support fixture 230 and the pressure ring 240 to descend until the pressure ring 240 abuts against the oil ring material. At this time, the inner support fixture 230 is located on the inner side of the oil ring material, and the inner fixture applies pressure to the inner wall of the oil ring material, thereby clamping the oil ring material. The pressing driving member 220 drives the lifting bracket 210 to reset, wherein the pressing driving member 220 can be a cylinder or a motor.
[0039] Please refer to Figure 3 The outer wall of the pressure ring 240 is provided with an annular protrusion 241, and the lower edge of the annular protrusion 241 is used as a pressure end (such as Figure 3 The position indicated by the mark A in the middle). When the pressure ring 240 contacts the oil ring material, the portion of the pressure ring 240 located below the annular protrusion 241 is sleeved inside the oil ring material to play a role in preliminary positioning. During the press-fitting process, the lower edge of the annular protrusion 241 contacts the upper edge of the oil ring material, and the oil ring material is pressed under the power of the press-fitting driving member 220, so that the oil ring material is pressed into the middle shell material.
[0040] Please refer to Figure 1, according to the requirements of the assembly process, two oil ring materials need to be assembled in the middle shell material. To improve production efficiency, the number of pressure rings 240 is two, and the two pressure rings 240 are arranged side by side. There is a height difference between the pressure application ends on the two pressure rings 240, so as to adapt to the assembly height difference of the oil ring material at different positions on the middle shell material.
[0041] Please refer to Figure 3 , on the outer wall of the pressure ring 240 and at a partial position of the annular protrusion 241, there is a clearance portion 242 provided. The clearance portion 242 is adapted to the pressure application end of the inner support fixture 230, such as the profiling jaw 232 below. Exemplarily, the clearance portion 242 is a through hole on the outer wall of the pressure ring 240, which can not only avoid the movement track of the pressure application end of the inner support fixture 230, but also keep the bottom edge of the pressure ring 240 intact, thus ensuring the mechanical strength of the pressure ring 240.
[0042] Please continue to refer to the figure. The inner support fixture 230 includes a three-jaw cylinder 231 and a profiling jaw 232. The profiling jaw 232 is connected to the output end of the three-jaw cylinder 231. The profiling jaw 232 has an arc-shaped side wall and can closely adhere to the inner wall of the oil ring material. Driven by the three-jaw cylinder 231, the profiling jaw 232 can abut against three positions on the inner wall of the oil ring material, which is beneficial to improving the force uniformity of the oil ring material. It should be noted that for the two pressure rings 240 with a height difference, the relative height of the abutting positions between the inner support fixture 230 and the oil ring material in the longitudinal direction can be the same or different.
[0043] Please refer to Figure 4 , the oil ring transfer mechanism 400 includes a first linear movement module 410 and a support plate 420. The length of the first linear movement module 410 is arranged along the second direction, and the second direction is indicated as the front-back direction. The support plate 420 is connected to the first linear movement module 410, and an oil ring positioning member 430 is installed on the support plate 420. The oil ring positioning member 430 has a profiling structure and is used to position the oil ring material. The number of the oil ring positioning members 430 and their positions in the first direction are both adapted to the number of the pressure rings 240 and their positions in the first direction. In this way, the support plate 420 moves to the lower part of the pressure ring 240 under the drive of the first linear movement module 410. The inner support fixture 230 and the pressure ring 240 follow the lifting bracket 210 to descend and clamp the oil ring material placed on the oil ring positioning member 430, so as to realize the automatic transfer of the oil ring material.
[0044] Exemplarily, please refer to Figure 4 and Figure 5 , the oil ring positioning member 430 includes a first positioning member 431 and a second positioning member 432. There is a height difference between the supporting surfaces of the first positioning member 431 and the second positioning member 432, such as Figure 5As shown by the middle mark H. Since there is a height difference in the press-fitting positions of the two oil ring materials within the middle housing material, setting a height difference on the supporting surfaces of the first positioning member 431 and the second positioning member 432 can fix the relative height of the two oil ring materials in the longitudinal direction, thus facilitating subsequent transfer and press-fitting without the need to add an additional height adjustment mechanism, which is beneficial to simplifying the mechanical structure.
[0045] Please refer to Figure 6 , the oil ring picking mechanism 500 includes a second linear movement module 510, a third linear movement module 520, and a rotation module 530. The length of the second linear movement module 510 is arranged along the first direction. The length of the third linear movement module 520 is arranged along the longitudinal direction and is installed on the second linear movement module 510. The rotation module 530 is installed on the third linear movement module 520, and an oil ring gripper 540 is installed at the output end of the rotation module 530. The third linear movement module 520 and the rotation module 530 can move along the first direction under the drive of the second linear movement module 510, so as to move between different bins of the oil ring feeding mechanism 300, so that the working range of the oil ring picking mechanism 500 covers multiple bins. The third linear movement module 520 can drive the rotation module 530 to perform a lifting movement, so that the oil ring gripper 540 installed at the output end of the rotation module 530 can pick up the oil ring materials stacked at different heights and take them out from the top of the bin. The rotation module 530 can drive the oil ring gripper 540 to rotate 180°, so as to rotate the oil ring material from the first side close to the oil ring feeding mechanism 300 to the second side close to the oil ring transfer mechanism 400.
[0046] Please refer to Figure 7 , the oil ring feeding mechanism 300 includes a base 310, a carrier plate 320, and a guide frame 330. The number of carrier plates 320 is multiple, and each carrier plate 320 is installed with a guide frame 330. Each bin includes a carrier plate 320 and the corresponding guide frame 330. The guide frame 330 is arranged along the longitudinal direction so that multiple oil ring materials can be stacked along the longitudinal direction. The carrier plate 320 is installed on the base 310, and a slide rail 340 is connected between the base 310 and the carrier plate 320, and the position of the carrier plate 320 relative to the base 310 can be adjusted to adapt to the position of the oil ring gripper 540, so that the oil ring gripper 540 can accurately pick up the oil ring material.
[0047] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
