[0002] In the modern automobile manufacturing industry, the motor is one of the core components of the car, and its installation process is crucial. In particular, the installation of the motor rotor is difficult to carry manually during the installation process due to its large weight and size, and usually requires the use of slings and lifting equipment to complete.

[0003] In the assembly process of the motor rotor, the commonly used hoist is designed as an L-shaped structure. When in use, the sleeve on the hoist is set on one end of the rotor shaft, and then lifted by a crane for transportation and assembly. However, the sleeve design of this L-shaped hoist can usually only adapt to rotor shafts of specific sizes. When facing motor rotors of different sizes, the operator has to replace the sleeve of the corresponding size. This step not only increases the complexity of the operation, but also brings additional costs and time burdens. More importantly, during the lifting process, since the direct contact between the sleeve and the surface of the rotor shaft is often not tight enough, there is a risk of the rotor slipping or shaking, which may not only damage the motor rotor, but also cause serious safety accidents.

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0019] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0020] In the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] Example 1: Reference Figure 1 and Figure 2, an automobile parts lifting equipment, including an L-shaped hanging plate 1 and a sleeve 2 transversely fixed on the bottom of the L-shaped hanging plate 1, and a lifting ring assembly 3 arranged above the top of the L-shaped hanging plate 1. When lifting the motor rotor, first hang the lifting ring assembly 3 arranged at the top of the L-shaped hanging plate 1 on the hook of the lifting equipment, and then adjust the L-shaped hanging plate 1 to the position of the motor rotor through the movement of the lifting equipment, and horizontally sleeve the sleeve 2 transversely fixed on the bottom of the L-shaped hanging plate 1 on one end of the motor rotor shaft to achieve a stable clamping, and finally, the lifting equipment lifts the motor rotor together with the sleeve 2, and transports it to the assembly position of the motor housing, completing the plug-in assembly process of the motor rotor and the motor housing.

[0022] Embodiment 2: Based on the above embodiment, considering that in the above technical solution, if the lifting ring assembly 3 is fixed at the top position of the L-shaped hanging plate 1, it will lack the flexibility to adjust the motor rotors of different weights, which may cause imbalance during the lifting process. This imbalance not only increases the risk of the motor rotor falling during lifting, thereby exacerbating the safety hazard, but also has an adverse effect on the assembly process of the motor rotor and the motor housing, thereby reducing the overall assembly efficiency. Therefore, based on this, it is further optimized to refer to Figure 1 , Figure 3 and Figure 4The lifting ring assembly 3 includes a circular plug-in block 31, and the L-shaped hanging plate 1 is provided with a plurality of adjustment holes 12 that are compatible with the circular plug-in block 31. A bent rod 32 located above the top of the L-shaped hanging plate 1 is fixed on one side of the circular plug-in block 31, and a connecting seat 33 is fixed on the other end of the bent rod 32. A concave groove 34 is provided at the bottom of the connecting seat 33, and a connecting shaft 1 35 is rotatably arranged between the side walls of the concave groove 34, and an L-shaped interference block 36 that fits the concave groove 34 is fixed on the connecting shaft 1 35. A threaded groove 37 is provided on the side of the circular plug-in block 31 corresponding to the L-shaped interference block 36, and a screw rod 38 that matches the threaded groove 37 is threadedly connected to the L-shaped interference block 36. A hexagonal rotating block 39 is fixed on the end corresponding to the outside of the L-shaped interference block 36, and the screw rod 38 is driven by the hexagonal rotating block 39 to rotate between the preset threaded hole on the L-shaped interference block 36 and the threaded groove 37. When the screw rod 38 is disengaged When leaving the threaded groove 37 and entering the threaded hole, the L-shaped interference block 36 can be rotated clockwise or counterclockwise along the concave groove 34 through the connecting shaft 35 to keep the L-shaped interference block 36 parallel to the connecting seat 33, so that the circular plug-in block 31 can be easily removed from the adjustment hole 12, and then the circular plug-in block 31 can be inserted into the adjustment hole 12 at other positions of the L-shaped hanging plate 1 according to the motor rotor of different weights. After the insertion is completed, the L-shaped interference block 36 is rotated to the vertical position again to ensure that the screw rod 38 is aligned with the threaded groove 37. Finally, by twisting the hexagonal rotating block 39, the screw rod 38 is tightly threadedly connected with the threaded groove 37, so that the lifting ring assembly 3 is firmly fixed at different positions on the top of the L-shaped hanging plate 1. This design is intended to enable the lifting ring assembly 3 to flexibly adapt to motor rotors of different weights and sizes, ensure balance during lifting, reduce safety hazards, and improve assembly efficiency.

[0023] It should be noted that the bottom of the connecting seat 33 is kept parallel to the top of the L-shaped hanging plate 1. In this way, when the L-shaped resistance block 36 is rotated to be parallel to the connecting seat 33 via the connecting shaft 35, it can smoothly cooperate with the circular plug-in block 31 to be smoothly pulled out from the adjustment hole 12. The circular plug-in block 31 is equipped with a pair of resistance plates 310 that fit tightly with the surface of the L-shaped hanging plate 1. After the L-shaped resistance block 36 is locked with the circular plug-in block 31, the resistance plate 310 can prevent the circular plug-in block 31 from accidentally falling off from the adjustment hole 12, thereby further enhancing the stability of the lifting ring assembly 3 during the lifting process.

[0024] Embodiment 3: Based on the above embodiment, considering that the sleeve 2 and the motor rotor are in rigid contact when they are sleeved, it is easy to cause damage to the motor rotor shaft during the lifting process, so based on this, refer to Figure 1 and Figure 2, and also includes an arc-shaped plate 4 symmetrically arranged inside the sleeve 2. The opposite sides of the two arc-shaped plates 4 are connected with matching gaskets 41. The gaskets 41 are made of polyethylene material and can provide effective buffering and protection when the sleeve 2 contacts the motor rotor shaft, reducing the friction and wear caused by rigid contact, thereby reducing the risk of damage to the motor rotor shaft.

[0025] At the same time, it is also considered that the end diameter of the sleeve 2 is usually a fixed size in actual use, and can only be used for motor rotor shafts within a specific diameter range. When the size of the motor rotor shaft does not match the sleeve 2, it is necessary to replace the sleeve 2 of the corresponding size or even the entire hanger, which not only increases the operating cost, but also reduces the work efficiency. Based on this, referring to Figure 5 and Figure 6 A pair of toggle plates 5 are provided on the outside of the sleeve 2, and a guide surface 51 inclined downward is provided on the toggle plate 5. A connecting piece 6 connected between the toggle plate 5 and the arc plate 4 is provided on the sleeve 2. The connecting piece 6 includes a transverse shell 61 fixed on the sleeve 2, and a cavity 62 is provided in the transverse shell 61. A plurality of cross bars 63 are slidably arranged on the transverse shell 61. One end of the cross bar 63 is fixed to one side of the toggle plate 5, and the other end of the cross bar 63 is fixed to a side of the arc plate 4 corresponding to the inner wall of the sleeve 2. A movable plate 64 that fits the inner wall of the cavity 62 is fixed on the cross bar 63, and a spring 65 fixed between the movable plate 64 and the side wall of the cavity 62 is sleeved on the cross bar 63. An adjusting groove 11 is provided on the L-shaped hanging plate 1, and an adjusting component 7 arranged on the adjusting groove 11 is linked between the two guide surfaces 51. When the driving adjustment component 7 moves down or up along the guide surface 51, it can simultaneously drive the two toggle plates 5 to drive the corresponding cross bars 63 to move toward or away from each other, thereby realizing that the two arc plates 4 are also adjusted toward or away from each other in the sleeve 2, thereby changing the size of the space inside the sleeve 2 to adapt to motor rotor shafts of different sizes. Through the linkage design of the adjustment component 7 and the toggle plate 5, a single sleeve 2 can be adapted to motor rotor shafts of different sizes without replacing sleeves 2 of different sizes. This greatly improves the flexibility and adaptability of the sling, reduces operating costs and time, and also avoids the complex structure and extra weight brought about by designing multiple sleeves 2 of different sizes under the bottom of the L-shaped hanging plate 1. This design makes the sling more concise, lightweight, and easy to carry and operate.

[0026] In addition, it should be noted that in the above technical solution, only one adjustable sleeve 2 is needed to meet the needs of motor rotor shafts of various sizes, which not only reduces the types and quantities of spare parts and reduces maintenance costs, but also reduces the possibility of failure due to the simplified structure. It is also worth mentioning that the two arc plates 4, under the coordinated linkage of the adjustment component 7 and the two toggle plates 5, not only realize the flexible adjustment of the internal space size of the sleeve 2 to adapt to motor rotor shafts of various sizes, but also ensure that the motor rotor shaft can be tightly and firmly clamped between the two arc plates 4. This tight-fitting design effectively prevents the motor rotor from falling due to loose clamping during the lifting process, thereby greatly improving the safety and reliability of the lifting process. Even when facing motor rotor shafts of different diameters, the operator can quickly achieve a firm clamping by simply adjusting the position of the arc plate 4, without having to worry about the motor rotor shaking or falling off during lifting. Potential safety hazards.

[0027] In order to realize the above technical solution, the adjustment component 7 can cooperate with the two arc plates 4 to be adjusted according to the size of the motor rotor shaft, wherein, referring to Figure 1 , Figure 7 and Figure 8 The adjusting assembly 7 includes a partition 71 fixed between the inner walls of the adjusting groove 11, a threaded sleeve 72 is fixed on the partition 71, a threaded rod 73 is threadedly connected to the threaded sleeve 72, and a pressure plate 74 is connected to the bottom end of the threaded rod 73 through a bearing. The pressure plate 74 is located on the outside of the adjusting groove 11. A pair of L-shaped support rods 75 are fixed on both sides of the corresponding sides, and a horizontal mounting plate 76 is fixed between the bottom ends of each pair of L-shaped support rods 75. A pair of vertical mounting blocks 77 are fixed to the bottom of the horizontal mounting plate 76. A connecting shaft 2 78 is rotatably arranged between the two vertical mounting blocks 77. A plurality of guide wheels 79 are fixed to the surface of the connecting shaft 2 78. The pressure plate 74 fits between the side walls of the adjusting groove 11, and a rotating portion 8 is provided at one end of the threaded rod 73 located above the top of the partition 71. The rotating portion 8 includes a fixed A circular twisting block 81 is fixed on the top of the threaded rod 73, and a pair of extension rods 82 are fixed on the outer contour surface of the circular twisting block 81. The end of the extension rod 82 corresponding to the side wall of the adjusting groove 11 does not contact the side wall of the adjusting groove 11. When the adjusting component 7 is in use, it is only necessary to twist the circular twisting block 81 and the extension rod 82 by hand to drive the threaded rod 73 to apply a positive force or a reaction force along the threaded sleeve 72, which will drive the pressure plate 74 to slide downward or upward along the side wall of the adjusting groove 11, so that the L-shaped support rod 75 connected to the pressure plate 74 will drive the guide wheel 79 designed at the bottom of the horizontal mounting plate 76 to move downward or upward along the guide surface 51. In this way, the position of the arc plate 4 can be accurately adjusted through the adjusting component 7 to adapt to motor rotor shafts of different sizes.

[0028] Embodiment 4: Based on the above embodiment, Figure 5and Figure 6 When the adjusting component 7 moves downward and cooperates with the two toggle plates 5 to move simultaneously, an air inlet cavity 42 is provided in the cushion sleeve 41, and a filter screen 43 connected to the inside of the air inlet cavity 42 is evenly distributed on the side of the cushion sleeve 41 that fits the external motor rotor shaft. A plurality of air guide pipes 44 are connected between the side wall of the cavity 62 and the air inlet cavity 42. The air guide pipes 44 are of a corrugated hose structure, and a hidden groove 45 for accommodating the air guide pipes 44 is provided on the inner wall of the sleeve 2. By adopting such a technical solution, the two toggle plates 5 will push the corresponding cross bars 63 to move toward each other during the process of the adjusting component 7 moving downward along the guide surface 51. In this process, the moving plate 64 on the cross bar 63 will slide along the inner wall of the cavity 62 and squeeze the spring 65. Due to the compression of the spring 65, the air The air inside the cavity 62 is compressed and enters the air inlet cavity 42 through the air duct 44. When the compressed air enters the air inlet cavity 42, it will be ejected through the filter 43. Due to the uniform distribution and small aperture of the filter 43, the ejected airflow can form a strong flushing effect, thereby effectively removing dust and impurities attached to the surface of the cushion sleeve 41, avoiding wear of the arc plate 4 and the motor rotor shaft during clamping and lifting, and extending the service life of the sling. When the adjustment component 7 completes the adjustment task and moves upward, the spring 65 will release its stored energy and push the moving plate 64 and the cross bar 63 to reset. At this time, the air pressure difference between the air inlet cavity 42 and the cavity 62 will prompt the air to flow back to the cavity 62 through the air duct 44, preparing for the next compression and dust removal process.

[0029] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
