Technical Field
[0001] The utility model relates to the technical field of motor assembly, in particular to a motor end cover assembly tool. Background Art
[0002] In the motor production process, the stator and the end cover on one side are usually tightly matched first, then the rotor is installed and the outer shell is put on, and then the end cover on the other side is assembled. The two end covers are fastened by bolts to complete the assembly of the motor. When connecting the two end covers, the bolt holes of the two end covers need to be completely aligned. The current conventional practice is to manually align the two end covers and hold them by hand, then press them with a press to maintain the alignment, and finally screw in the bolts. In this way, on the one hand, the stability of manual alignment is poor. Once there is an error, the bolts are difficult to screw in, and the press needs to be loosened for adjustment, which affects work efficiency; on the other hand, the labor intensity of workers is high, especially the eyes are prone to fatigue.

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0018] like Figure 1As shown, this embodiment provides a motor end cover assembly tool, including a base 1, a vertical plate 2 arranged on the base, two end cover positioning plates 3 respectively arranged at the upper and lower parts of the side surfaces of the vertical plate 2, and a press (not shown in the figure) arranged above the base 1, the end cover positioning plate 3 has an arcuate surface 31 adapted to the side surface of the motor end cover, the arcuate surface 31 is provided with a positioning groove 311 adapted to the motor end cover lug, and the base 1 is provided with a rotor avoidance groove 11. The working principle of this tool is as follows: first, after the two end covers of the motor are preliminarily aligned, they are placed on the base 1. Since the press needs to press on the upper end of the entire motor, the exposed end of the rotor needs to face downward and be inserted into the rotor avoidance groove 11 to ensure that the entire motor can be placed stably on the base; then, the entire motor is moved closer to the side of the vertical plate 2 until the upper and lower end covers respectively contact the arc-shaped surfaces 31 of the upper and lower end cover positioning plates 3, and through a slight squeezing operation, the lugs on the upper and lower end covers are fitted with the positioning grooves 311 on the end cover positioning plates 3. At this time, the upper and lower end covers are accurately aligned, that is, the lugs on the upper and lower end covers are aligned with each other; then, the press is used to press the entire motor from the upper end to maintain the stability of the end cover alignment state, and the bolts can be screwed into the lugs of the upper and lower end covers to complete the assembly of the motor end covers.
[0019] Specifically, in order to facilitate adjustment of the height position of the end cover positioning plate 2 to improve the applicability of the tooling, two vertical first strip holes 21 are provided on the vertical plate 2, and the end cover positioning plate 3 is connected to the two first strip holes 21 by bolts to facilitate adjustment of the end cover positioning plate to any height position of the vertical plate.
[0020] In order to ensure the horizontality of the end cover positioning plate 3 and to ensure that its arc surface 31 can accurately fit with the motor end cover, a first slot is provided on the end of the end cover positioning plate 3 facing away from the arc surface 31, and the vertical plate 2 is snapped into the first slot, and the lateral width of the first slot is the same as the width of the vertical plate 2, so that when the vertical plate 2 is in a vertical state, the horizontality of the end cover positioning plate 3 snapped with it is guaranteed. Similarly, in order to ensure that the vertical plate 2 can be stably in a vertical state, a second slot is provided at one end of the base 1, and the vertical plate 2 is snapped into the second slot, and the lateral width of the second slot is the same as the width of the vertical plate, so that the vertical plate 2 can stably maintain a perpendicular relationship with the base support surface, and accordingly, the end cover positioning plate 3 can maintain a parallel relationship with the base support surface, and no matter whether the base 1 is in a horizontal plane, the end cover positioning plate 3 can accurately match the side of the end cover of the motor placed on the base 1.
[0021] As described above, the snap-fitting relationship between the vertical plate 2 and the base 1 can ensure the accuracy of their assembly position. Therefore, in order to simplify the processing, the length of the first strip hole 21 can be extended, and the vertical plate 2 and the base 1 can be directly connected at the two first strip holes 21 by bolts without the need to additionally process a hole connecting the two.
[0022] In order to further simplify the operation of the workers, a magnet 4 is provided between the upper and lower end cover positioning plates 3 on the side of the vertical plate 2, so that when the preliminarily assembled motor is close to the vertical plate 2, it will be attracted by the magnet 4 and automatically complete the fitting action between the motor end cover and the end cover positioning plate 3. In order to cooperate with the up and down position adjustment function of the end cover positioning plate 3, a vertical second strip hole 22 is provided on the vertical plate 2, and the magnet 4 is connected to the second strip hole 22 by bolts, and the second strip hole 22 is located between the two first strip holes 21.
[0023] In order to take into account the stability of the base supporting the motor and the convenience of manual operation, the rotor avoidance groove 11 includes a precision part 111 close to the side of the vertical plate 2 and an adjustment part 112 away from the side of the vertical plate 2, and the width of the adjustment part 112 is greater than the width of the precision part 111. In this way, when the worker places the motor on the base 1, he can first insert the rotor into the adjustment part 112 with a larger width. The precision requirement of this operation is relatively low. Then, after the motor is supported by the base 1, the rotor is moved to enter the precision part 111. At this time, the entire motor gradually approaches the vertical plate 2. Among them, the length of the precision part 111 is greater than the length of the adjustment part 112, so as to ensure that the part of the base 1 close to the vertical plate 2 can stably support the lower end cover of the motor, and avoid that too much of the lower end cover falls into the rotor avoidance groove 11, which affects the stability of its upright state.
[0024] The above is only a preferred specific implementation of the utility model, which is a realization method based on the overall concept of the utility model, and the protection scope of the utility model is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
