Embodiment 1

[0037] An assembly device for a built-in motor of an electric motorcycle, such as figure 1 , 2 As shown in . The bottom of the transition plate 6 is connected with a transition plate 6, the bottom of the transition plate 6 is provided with a pressure applying mechanism 7, the upper mold 11 is fixedly installed on the bottom of the pressure applying mechanism 7, the lower mold 12 is fixedly installed on the top outer wall of the base 1, the base 1 and the transition plate 6 Two groups of symmetrical supporting mechanisms 3 are provided on the outer wall on the opposite side. The driving mechanism 5 includes a motor 13 and a rotating shaft 14. At least three load-bearing plates 15 are fixed on the top outer wall of the top plate 4 by bolts. The rotating shaft 14 is rotatably connected to the On the inner wall of the bearing plate 15, the motor 13 is fixed on the outer wall of one of the bearing plates 15 by bolts, and its output shaft is connected with the rotating shaft 14 throu...

Embodiment 2

[0040] An assembly device for a built-in motor of an electric motorcycle, such as figure 2 As shown, in order to solve the limit problem; this embodiment makes the following improvements on the basis of Embodiment 1: the pressure applying mechanism 7 includes a slide bar 22 and a spring 2, and the bottom of the slide bar 22 is fixed to the On the top outer wall of the upper mold 11 , the outer wall of the second slide bar 22 is slidably connected to the inner wall of the transition plate 6 , and the second spring is sleeved on the outer wall of the second slide bar 22 .

[0041] When this embodiment is in use, it is difficult to maintain the pressing distance and the pressing force after the pressing is in place no matter whether the cylinder, oil cylinder, threaded screw or the device is used for pressing, and the device is equipped with two springs. , the pressing force is applied to the upper mold 11 through the spring 2. On the one hand, the elastic force of the spring 2 ...

Embodiment 3

[0043] An assembly device for a built-in motor of an electric motorcycle, such as Figure 4 As shown, in order to solve the limit problem; this embodiment makes the following improvements on the basis of embodiment 2: the connecting assembly 19 includes two screw rods 23 and a sleeve 24, and the two screw rods 23 rotate in opposite directions The two sides of the sleeve 24 are threadedly connected, and the outer walls of the two screw rods 23 are threaded with locknuts 25 .

[0044] When this embodiment is in use, the device is provided with a screw rod 23 and a sleeve 24. When the sleeve 24 is twisted, it can change the length of the entire connecting assembly 19 through thread action, so that the device, on the one hand, is used for fixing For different types of rotors, the pressing force can be adjusted by twisting the sleeve 24. On the other hand, for different types of rotors, the pressing distance can be adjusted by twisting the sleeve 24, which is more practical.

Abstract

The invention discloses an assembling device for a built-in motor of an electric motorcycle, and relates to the technical field of motor assembling. An efficiency problem is solved. The device specifically comprises a base, an upper die and a lower die, the upper die and the lower die are identical in structure, a top plate is fixedly mounted on the outer wall of the top of the base through supporting columns, a driving mechanism is arranged at the top of the top plate, a transition plate is connected to the bottom of the driving mechanism, and a pressure applying mechanism is arranged at the bottom of the transition plate; the upper die is fixedly installed at the bottom of the pressure applying mechanism, the lower die is fixedly installed on the outer wall of the top of the base, and two sets of symmetrical supporting mechanisms are arranged on the outer wall of the side, opposite to the transition plate, of the base. When the motor rotates, the motor drives a cam to rotate, the cam and a roller are matched to enable a limiting frame to press the transition plate downwards through a connecting assembly so as to press the upper die downwards, the upper die is matched with the lower die, a bearing inner ring and a rotor shaft as well as a bearing outer ring and an end cover are pressed, manual pressing is not needed, convenience and labor saving are achieved, and efficiency is high.

Description

technical field [0001] The invention relates to the technical field of motor assembly, in particular to an assembly device for a built-in motor of an electric motorcycle. Background technique [0002] As a convenient means of transportation, motorcycles are very popular among people. However, with the slogan of energy saving, emission reduction and environmental protection, most of the original fuel motorcycles have been changed into electric motorcycles, and one of the core components of electric motorcycles is the electric motor, and the electric motor During assembly, the rotor and stator need to be combined. In actual factory processing, after the stator is pressed into the housing, the two ends of the rotor shaft are respectively fitted with bearings, the bearings are pressed into the end cover, and the end covers on both sides are pressed together. Assemble the housing with the stator. [0003] After retrieval, the Chinese Patent Publication No. is CN106026541B, which...
