Description

Technical Field

[0001] The utility model belongs to the technical field of motor pair wheel disassembly, and in particular relates to a device for disassembling a motor pair wheel. Background Art

[0002] Motor-to-wheel is a structure that directly combines the motor and the wheel, generally consisting of a motor, a reducer and a wheel. When the motor-to-wheel is working, the motor drives the reducer to rotate, and the reducer then decelerates and transmits the power to the wheel, thereby realizing the power output of the vehicle. Due to the advantages of simple structure and high transmission efficiency, the motor-to-wheel is widely used in electric vehicles, bicycles and other fields.

[0003] In large-scale production factories that use motor wheels, the motor wheels need to be inspected and replaced from time to time. During the inspection and replacement, the motor wheels need to be removed from the motor shaft. Existing disassembly tools require the cooperation of multiple people to complete the disassembly. At the same time, the disassembly process is slow and there are many safety hazards. The universality of motor wheels of different sizes is poor, and it cannot meet the requirements of motor wheel maintenance in large factories. Utility Model Content

[0004] The utility model aims to provide a device for disassembling a motor pair of wheels, so as to solve the problem that the disassembly of the motor pair of wheels is time-consuming and labor-intensive, resulting in poor efficiency.

[0005] The technical solution of the utility model is: a device for disassembling a pair of motor wheels, comprising a frame, a jack and a limit device, the limit device comprising a fixed plate and a limit plate, the frame is a cubic structure, lifting brackets are respectively arranged on opposite sides of the frame, the jack is arranged on the two lifting brackets, the jack push end extends out of the frame, the bottoms of the two vertical sides of the frame in the same direction as the jack push end are respectively hinged with connecting plates, the other end of the connecting plate is hinged with the fixed plate, a connecting hole is arranged at the end of the connecting plate, a limit plate is detachably arranged on the connecting hole, and the limit plate is located above the jack push end.

[0006] As a further improvement of the utility model, wheels are provided at the bottom of the frame.

[0007] As a further improvement of the utility model, an operating table is provided on the top of the frame.

[0008] As a further improvement of the utility model, a tool box is arranged in the frame.

[0009] As a further improvement of the utility model, wear-resistant and anti-skid pads are respectively provided on both side surfaces of the fixing plate and one side of the limiting plate.

[0010] The beneficial effects of the utility model are as follows: the utility model is used to facilitate the time-saving and labor-saving disassembly of the motor wheel pair in different use environments.

The limit plate set between the connecting plates can limit the opening and closing of the connecting plates. The motor wheel pair is placed between the limit plate and the fixed plate on the connecting rod. The jack can be adjusted by lifting to adapt to the disassembly environment of different heights. Finally, the motor shaft is pushed by the jack to make the limited motor wheel pair fall off, thereby completing the disassembly work.

[0011] The wheels at the bottom of the frame can move the device more flexibly, and the operating table can be operated by one person, saving labor and making the operation more convenient. The tool box in the frame increases the diversity of the use of the device and maximizes its use. The wear-resistant and anti-skid pads can increase friction and prevent the motor from causing wear when the wheel limit is fixed, thereby affecting its use.

[0018] Embodiment 1,

[0019] The frame 1 is a rectangular cube structure, and inspection doors can be set on both sides to facilitate opening for inspection; a 30mm thick scrap steel plate is cut into a size of 600×120mm as a connecting plate 4, and then a hole of M30 diameter is drilled at one end of the connecting plate 4 with a drill press, and a 20# round steel is set at the bottom of the two vertical sides of the frame 1, and the connecting plate 4 is set on the round steel through the drilled hole, so that the round steel is hinged to the bottom of the frame 1 as a pin; a plurality of connecting holes 6 are opened on the other end of the connecting plate 4 to adapt to motor wheels of different sizes, which is more practical; a hole is drilled at the other end of the connecting plate 4, and a 20# round steel is set in the drilled hole. #Round steel is used as a pin to make a connecting plate with a size of 180×80mm. A hole of M30 is drilled on the connecting plate with a drill press. The connecting plate is hinged on the round steel through the hole. The fixing plate 5 is connected through the connecting plate. The fixing plate 5 is cut into a rectangular plate of 500×300mm using 30mm scrap steel plate. Wear-resistant and anti-skid pads 11 are set on both sides of the fixing plate 5; a limit plate 7 with a size of 600×150mm is cut from a 30mm steel plate. A hole of M30 is drilled at both ends of the limit plate 7 with a drill press, and a wear-resistant and anti-skid pad 11 is set on the side of the limit plate 7 opposite to the fixed plate 5.
