Description

Technical Field

[0001] The present invention relates to the technical field of motor processing, and in particular to a motor retaining spring press. Background Art

[0002] The in-wheel motor is a motor designed by integrating the vehicle's power system, transmission system, and braking system, omitting a large number of transmission components and making the vehicle structure simpler. The flywheel is an important component of the in-wheel motor. It is installed on the end cover of the in-wheel motor. The end cover is designed with a stop. The retaining spring is usually connected to the outside of the stop through its own elastic force to prevent the flywheel from loosening out of the end cover.

[0003] When the retaining spring is installed on the stop, the two ends of the retaining spring need to be pried apart to expand the inner ring of the retaining spring, and then the retaining spring can be sleeved on the outside of the stop. However, currently, prying apart the retaining spring manually or mechanically can easily cause excessive elastic deformation of the retaining spring, making the retaining spring easily damaged. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art and to provide a motor retaining spring press.

[0005] One embodiment of the present invention provides a motor retaining spring press assembly machine, comprising: a frame, a lifting frame, a lifting device, and a clamping mechanism;

[0006] The frame is provided with a positioning seat, the lifting frame is lifted and lowered above the positioning seat by the lifting device, and the clamping mechanism is provided on the lifting frame;

[0007] The clamping mechanism includes a rotation drive assembly, a first gear, a second gear, and two circlip clamping needles. The first gear and the second gear are arranged side by side on the lifting frame and mesh with each other. The rotation drive assembly is arranged on the lifting frame and is in transmission connection with the first gear. The two circlip clamping needles are respectively connected to the first gear and the second gear and are located at the bottom of the lifting frame.

[0008] The first gear and the second gear are both provided with a plurality of small teeth, and the plurality of small teeth are arranged in sequence around the first gear and the second gear respectively. The first gear and / or the second gear are also provided with a plurality of large teeth, and the plurality of large teeth are located between two adjacent small teeth. The tooth thickness of the large teeth is greater than the tooth thickness of the small teeth, and the full tooth height of the large teeth is greater than the full tooth height of the small teeth. When the first gear and the second gear rotate together to move the large teeth between the first gear and the second gear, the large teeth support the first gear and the second gear to move the second gear away from the first gear, thereby making the two retaining spring clamping needles move away from each other.

[0009] Compared with the prior art, the motor retaining spring press of the present invention uses the size difference between the large tooth part and the small tooth part to enable the large gear to support the first gear and the second gear when the first gear and the second gear rotate, thereby driving the two retaining spring clamping needles to separate from each other by a small distance, so that the clamped retaining spring is supported by the two retaining spring clamping needles so that the retaining spring can be installed on the end cover. Since the retaining spring will only produce a slight elastic deformation, the retaining spring can be installed conveniently while also helping to avoid the situation where the retaining spring is easily damaged.

[0010] In some optional embodiments, the first gear and the second gear are both provided with a plurality of large teeth, and the first gear and the second gear are meshed with each other through the large teeth and the small teeth.

[0013] In some optional embodiments, a limiting groove is provided on the inner wall of the limiting hole, a limiting block extending into the limiting groove is provided on the outer side of the rotating shaft, and an elastic structure connected to the limiting block is also provided in the limiting groove.

[0014] In some optional embodiments, a guide portion is provided at the bottom end of the retaining spring clamping needle, and a horizontal cross-section of the guide portion gradually decreases in a direction from top to bottom.

[0015] In some alternative embodiments, the circlip press-fitting machine for the motor further includes: a first feeding device, the first feeding device includes a first translation driving assembly and a tray, the tray is movably arranged on the frame, a positioning portion for positioning and cooperating with the circlip is arranged on the tray, and the tray moves to below the circlip clamping needle under the drive of the first translation driving assembly.

[0016] In some alternative embodiments, a circlip storage cylinder is arranged on the frame, the circlip storage cylinder is arranged above the tray, the positioning portion is a groove arranged on the tray, and the first translation driving assembly drives the tray to move so that the positioning portion moves between below the circlip clamping needle and below the circlip storage cylinder. When the positioning portion moves to below the circlip storage cylinder, the circlip on the circlip storage cylinder falls into the positioning portion.

[0017] In some alternative embodiments, a positioning protrusion is arranged on the outer side of the circlip storage cylinder, the positioning protrusion extends in the up-down direction. When the circlip is sleeved on the outer side of the circlip storage cylinder, both ends of the circlip are respectively located on both sides of the positioning protrusion.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. In the description of the present invention, unless otherwise specified, "a plurality of" means two or more, and "several" means one or more. In addition, unless otherwise specified, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 It is a schematic structural diagram of a circlip press-fitting machine for a motor according to an embodiment of the present invention, Figure 2 It is a schematic structural diagram of one side of a partial structure of a circlip press-fitting machine for a motor according to an embodiment of the present invention. The circlip press-fitting machine for the motor includes: a frame 10, a lifting frame 20, a lifting device 30, and a clamping mechanism 40.

[0032] Please refer to Figure 3 and Figure 4 ,Figure 3 This is a schematic structural diagram of one side of a partial structure of a motor retaining spring press assembly machine according to an embodiment of the present invention. Figure 4 yes Figure 3 As shown in the enlarged view of point A, a positioning seat 11 is provided on the frame 10, and the positioning seat 11 is used to position the end cover. The lifting frame 20 is lifted and lowered above the positioning seat 11 by the lifting device 30, and the clamping mechanism 40 is provided on the lifting frame 20; the clamping mechanism 40 includes a rotation drive assembly 41, a first gear 42, a second gear 43 and two retaining spring clamping needles 44, the first gear 42 and the second gear 43 are arranged side by side on the lifting frame 20 and mesh with each other, the rotation drive assembly 41 is provided on the lifting frame 20, and is in transmission connection with the first gear 42, the two retaining spring clamping needles 44 are respectively connected to the first gear 42 and the second gear 43, and are located at the bottom of the lifting frame 20.

[0033] See also Figure 5 , which is a structural schematic diagram of the first gear and the second gear of an embodiment of the present invention. The first gear 42 and the second gear 43 are both provided with a plurality of small teeth 45, and the plurality of small teeth 45 are arranged in sequence around the first gear 42 and the second gear 43 respectively. The first gear 42 and / or the second gear 43 are also provided with a plurality of large teeth 46, and the plurality of large teeth 46 are located between two adjacent small teeth 45. The first gear 42 and the second gear 43 are meshed by the small teeth 45 and the large teeth 46. The tooth thickness of the large teeth 46 is greater than the tooth thickness of the small teeth 45, and the full tooth height of the large teeth 46 is greater than the full tooth height of the small teeth 45.

[0034] The retaining spring 70 is C-shaped, and retaining holes 71 are provided on both ends of the retaining spring 70, and the retaining spring clamping needle 44 extends into the retaining hole 71, and then the rotating drive assembly 41 drives the first gear 42 to rotate, and the first gear 42 drives the second gear 43 to rotate together, and the first gear 42 and the second gear 43 rotate together to move the large tooth portion 46 between the first gear 42 and the second gear 43, and the large tooth portion 46 opens the first gear 42 and the second gear 43 to move the second gear 43 away from the first gear 42, thereby causing the two retaining spring clamping needles 44 to move away from each other, and the two ends of the retaining spring 70 are driven away from each other by the spring clamping needles, so that the retaining spring 70 is expanded, and then the lifting device 30 drives the lifting frame 20 to descend, so that the retaining spring 70 is pressed into the stop of the end cover positioned on the positioning seat 11, thereby realizing the assembly of the retaining spring 70. Since the rotation of the first gear 42 and the second gear 43 is relatively easy to accurately control, the large tooth portion 46 can stably open the first gear 42 and the second gear 43 by a small distance, thereby realizing the precise movement of the position of the spring clamping needle, which is beneficial to control the elastic deformation of the retaining spring 70 within an appropriate range and avoid excessive elastic deformation of the retaining spring 70 during the installation process.

[0035] The rotation drive assembly 41 can be designed according to actual needs. For example, the rotation drive assembly 41 can use a motor, preferably a servo motor, so as to improve accuracy, but this is not limited to this example.

[0036] The lifting device 30 can be designed according to actual needs. For example, the lifting device 30 can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly.

[0037] In some alternative embodiments, a plurality of large tooth portions 46 are provided on both the first gear 42 and the second gear 43. The first gear 42 and the second gear 43 are meshed with each other through the large tooth portions 46 and the small tooth portions 45. When the first gear 42 and the second gear 43 rotate so that the large tooth portions 46 of the first gear 42 and the large tooth portions 46 of the second gear 43 are meshed with each other, the large tooth portions 46 of the first gear 42 and the large tooth portions 46 of the second gear 43 are correspondingly abutted against each other so as to spread the first gear 42 and the second gear 43 apart from each other, which is beneficial to improving the meshing stability.

[0038] In some alternative embodiments, the difference between the tooth thickness of the large tooth portion 46 and the tooth thickness of the small tooth portion 45 is 0.5 - 2.5 mm, and the difference between the full tooth height of the large tooth portion 46 and the full tooth height of the small tooth portion 45 is 0.5 - 2.5 mm. In this embodiment, the difference between the tooth thickness of the large tooth portion 46 and the tooth thickness of the small tooth portion 45 is 1 mm, and the difference between the full tooth height of the large tooth portion 46 and the full tooth height of the small tooth portion 45 is 1 mm. When the large tooth portions 46 of the first gear 42 and the large tooth portions 46 of the second gear 43 are correspondingly abutted against each other so as to spread the first gear 42 and the second gear 43 apart from each other, the distance between the first gear 42 and the second gear 43 increases by 2 mm, so that the two spring clamping needles are separated from each other by 2 mm.

[0039] Please refer to Figure 6, which is a cross-sectional view of a partial structure of a circlip press-fitting machine for a motor according to an embodiment of the present invention. In order to facilitate the floating of the second gear 43, in some alternative embodiments, a limiting hole 21 is provided on the lifting frame. The second gear 43 is rotationally engaged with the limiting hole 21 through a rotating shaft 48. A floating gap 22 is formed between the inner wall of the limiting hole 21 and the rotating shaft 48. When the second gear 43 moves away from the first gear 42, the rotating shaft 48 moves relative to the limiting hole 21 in the radial direction of the limiting hole 21. Of course, the setting manner of the second gear 43 is not limited thereto. Those skilled in the art can also select other suitable structures according to the teachings of the present invention. For example, a rotating column is provided on the lifting frame 20, the second gear 43 is rotatably arranged outside the rotating column, and an elastic ring is arranged between the inner ring of the second gear 43 and the rotating column. When the second gear 43 moves away from the first gear 42, the elastic ring generates elastic deformation. After the large tooth portion 46 disengages from between the first gear 42 and the second gear 43, the elastic ring then resets the second gear 43 through elastic force, so that the second gear 43 remains meshed with the first gear 42.

[0040] In some alternative embodiments, a limiting groove 23 is provided on the inner wall of the limiting hole 21, a limiting block 49 extending into the limiting groove 23 is provided on the outer side of the rotating shaft 48, and an elastic structure 24 connected to the limiting block 49 is further provided in the limiting groove 23. The elastic structure 24 can reset the second gear 43. Preferably, two limiting holes 21 are provided on the lifting frame 20, and the two limiting holes 21 are located on the upper and lower sides of the second gear 43, so as to facilitate improving the translational stability of the second gear 43. The elastic structure 24 can be a spring, a metal elastic sheet or an elastic rubber pad, etc.

[0041] In some alternative embodiments, a guiding portion 47 is provided at the bottom end of the circlip clamping needle 44. The horizontal cross-section of the guiding portion 47 gradually decreases in the direction from top to bottom, so as to facilitate the circlip clamping needle 44 to extend into the clamping hole 71 of the circlip 70 and make the circlip 70 clamped on the circlip clamping needle 44.

[0042] Please refer to Figure 7, which is a schematic structural diagram of the top of the first feeding device according to an embodiment of the present invention. For the convenience of feeding, in some alternative embodiments, the snap ring press-fitting machine of the motor further includes: a first feeding device 50, the first feeding device 50 includes a first translation driving assembly 51 and a tray 52, the tray 52 is movably arranged on the frame 10, a positioning portion 53 for positioning and cooperating with the snap ring 70 is arranged on the tray 52, the tray 52 is moved to the lower part of the snap ring clamping needle 44 under the drive of the first translation driving assembly 51, so as to convey the snap ring 70 to the position corresponding to the snap ring clamping needle 44, then the lifting device 30 drives the lifting frame 20 to descend, so that the snap ring clamping needle 44 is inserted into the snap hole 71 of the snap ring 70, and the two snap ring clamping needles 44 are separated under the drive of the first gear 42 and the second gear 43, so that the snap ring 70 is clamped on the snap ring clamping needle 44 by its own elasticity, the lifting device 30 drives the lifting frame 20 to ascend, and the tray 52 is driven by the first translation driving assembly 51 to move away from the snap ring clamping needle 44, so that the tray 52 does not block the moving path of the snap ring 70 to the positioning seat 11.

[0043] Please refer to Figure 8, which is a schematic structural diagram of the first loading device and the circlip storage barrel of one embodiment of the present invention. To facilitate the automatic loading of the circlip 70, in some optional embodiments, a circlip storage barrel 54 is provided on the frame 10. The circlip storage barrel 54 is arranged above the material tray 52. The positioning portion 53 is a groove provided on the material tray 52. The first translation drive assembly 51 is used to drive the material tray 52 to move so that the positioning portion 53 moves between below the circlip clamping needle 44 and below the circlip storage barrel 54. When the positioning portion 53 moves to below the circlip storage barrel 54, the circlip 70 on the circlip storage barrel 54 falls into the positioning portion 53, and then the material tray 52 drives the material tray 52 to move below the circlip clamping needle 44. The retaining ring 70 on the retaining ring storage barrel 54 falls down by its own gravity. This design makes the depth of the positioning portion 53 match the height of the retaining ring 70, and the bottom of the retaining ring storage barrel 54 is roughly flush with the top of the material tray 52 without colliding with each other. When the first translation assembly drives the material tray 52 so that the positioning portion 53 moves to the bottom of the retaining ring clamping needle 44, the top of the material tray 52 is always located at the bottom of the retaining ring storage barrel 54, thereby preventing the retaining ring 70 on the retaining ring storage barrel 54 from falling. Only when the retaining ring 70 on the material tray 52 is clamped away and the positioning portion 53 moves to the retaining ring When the material storage barrel 54 is below the material storage barrel 54, the retaining spring 70 on the retaining spring storage barrel 54 falls into the positioning portion 53 by its own gravity. Since the positioning portion 53 can only accommodate one retaining spring 70, after the lowest retaining spring 70 on the retaining spring storage barrel 54 falls into the positioning portion 53, the other retaining springs 70 are blocked by the retaining springs 70 in the positioning portion 53 and cannot escape from the retaining spring storage barrel 54. Even if the material tray 52 moves, the retaining springs 70 will be held back and prevented from falling, so that the retaining springs 70 can be transported one at a time to the bottom of the retaining spring clamping needle 44 under the movement of the material tray 52. Of course, the structure of the retaining spring storage barrel 54 is not limited to this. Those skilled in the art can also choose other suitable structures according to the teachings of the present invention. For example, a receiving chamber for receiving the retaining springs 70 is provided in the retaining spring storage barrel 54, and a leak and a movable blocking member driven by a cylinder are provided at the bottom of the receiving chamber to release the retaining springs 70 in the receiving chamber at one time through the movable blocking member.

[0044] In order to facilitate the positioning of the angle of the retaining spring 70, in some optional embodiments, a positioning protrusion 55 is provided on the outside of the retaining spring storage barrel 54, and the positioning protrusion 55 extends from top to bottom. When the retaining spring 70 is sleeved on the outside of the retaining spring storage barrel 54, the two ends of the retaining spring 70 are respectively located on both sides of the positioning protrusion 55, so that the retaining spring 70 will not rotate relative to the retaining spring storage barrel 54, and the positioning portion 53 should also match the structure of the retaining spring 70 to avoid the retaining spring 70 from being offset in angle or position.

[0045] In order to improve the degree of automation, in some alternative embodiments, the snap ring press-fitting machine for the motor further includes: a second feeding device, which includes a second translation driving assembly 60 and a clamping mechanism 61. The second translation driving assembly 60 is used to drive the clamping mechanism 61 to approach or move away from the positioning seat 11. The clamping mechanism 61 is used to clamp the end cover, and a flywheel is installed on the end cover. After the clamping mechanism 61 clamps the end cover stably, the second translation driving assembly 60 moves the end cover to the positioning seat 11. The second feeding device further includes an end cover conveying mechanism 62, a flywheel conveying mechanism 63 and a flywheel tightening mechanism 64. The end cover conveying mechanism 62 drives the end cover to move to the clamping mechanism 61 after passing through the flywheel conveying mechanism 63 and the flywheel tightening mechanism 64. The flywheel conveying mechanism 63 conveys the flywheel to the end cover, and the flywheel tightening mechanism 64 tightens the flywheel on the end cover. The clamping mechanism 61 clamps the end cover on the end cover conveying mechanism 62.

[0046] The first translation driving assembly 51 and the second translation driving assembly 60 can be designed according to actual needs. For example, the first translation driving assembly 51 and the second translation driving assembly 60 can be screw driving assemblies, rotary motor translation driving assemblies, belt translation driving assemblies, cylinder translation driving assemblies or linear motor translation driving assemblies.

[0047] The clamping mechanism 61 can be a mechanical claw or two clamping and cooperating clamping plates controlled by a cylinder, and this is not limited to this example.

[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
