Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor processing, in particular to an assembly tool for a rotor rear bearing. Background Art
[0002] Before the existing motor rotor is installed with the stator, it is necessary to sleeve the bearing on the outer wall of the rotor shaft. The existing bearing assembly method is to squeeze the bearing to the outer wall of the rotor shaft at a specified height by manual pressing. However, this assembly method requires manual alignment of the rotor shaft and the bearing, which greatly reduces the assembly efficiency. If the bearing position deviates during assembly, the bearing will be broken, affecting the surrounding working environment and causing damage to the bearing. In addition, the rotor and the bearing need to be continuously raised and lowered at the work station during the assembly process, and there is a lack of positioning devices for the rotor and the bearing, resulting in low production efficiency. Therefore, a rotor rear bearing assembly tool is required. Utility Model Content
[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a rotor rear bearing assembly tool to solve the problem of positioning processing when assembling the rotor shaft and the bearing in the prior art.
[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:
[0005] A rotor rear bearing assembly tool, comprising:
[0006] A base, a bearing plate is provided on one side of the base, the bearing plate and the base are spaced apart, an inclined feed plate is provided on the upper side of the spacer surface, and a bearing positioning plate connected to the feed plate is provided on the inner side of the bearing plate;
[0007] An assembly drive member is arranged in the interval space between the bearing plate and the base, a rotor seat is arranged at the movable end of the assembly drive member, the assembly drive member drives the rotor seat to move toward the bearing plate, and when the assembly drive member has a maximum stroke, the main shaft on the rotor seat extends into the bearing positioning plate.
[0008] To implement the above technical solution, the base and the bearing plate cooperate with each other, the bearing plate is used to place the bearing, and the base carries the rotor, so that positioning structures can be formed for the rotor and the bearing respectively, thereby avoiding the tediousness of manual positioning. A rotor seat is provided at the movable end of the assembly drive member. When the bearing needs to be assembled, the rotor is placed on the rotor seat, the rotor is positioned by the rotor seat, the bearing to be installed is placed in the bearing positioning plate, and the assembly drive member is used to drive the rotor seat to move toward the bearing plate. Moreover, when the stroke is maximum, the main shaft on the rotor seat extends into the bearing at the bottom of the bearing positioning plate, thereby completing the action of assembling the bearing on the rotor main shaft.
[0009] In one embodiment of the present invention, the bearing positioning plate is a V-shaped positioning plate, and a positioning groove capable of accommodating a single bearing is provided at the bottom of the bearing positioning plate, and the positioning groove maintains coaxiality with the assembly drive member.
[0010] To implement the above technical solution, setting the bearing positioning plate as a V-shaped positioning plate can facilitate the loading of bearings. A large number of bearings can form a conical material pile in the space between the bearing positioning plate and the bearing plate, and the width between the bearing positioning plate and the bearing plate can only accommodate the width of one bearing. In this way, the bearing at the bottom between the bearing positioning plate and the bearing plate can always remain single, thereby ensuring the continuity of the bearing installation.
[0011] In an embodiment of the present invention, the side of the positioning groove close to the assembly driving member is an open end surface.
[0012] To implement the above technical solution, the radial dimensions of the open end face can match the radial dimensions of the bearing, so that after the bearing is installed on the main shaft, the assembly drive drives the rotor seat to move away from the bearing plate, and the main shaft brings the bearing out, thereby facilitating the bearing to continue to fall into the positioning groove. When the bearing falls to the bottom of the positioning groove, the radial pressure generated by the stacked bearings will prevent the bearing from falling from the open end face.
[0013] In an embodiment of the present invention, the inner surfaces on both sides of the bearing positioning plate are smooth curved surfaces.
[0014] Implementing the above technical solution can facilitate the bearing to fall into the assembly working surface at the bottom.
[0015] In one embodiment of the present invention, a bearing limiting platform is provided on the outer side of the bearing plate at the positioning groove.
[0016] To implement the above technical solution, the setting of the bearing limit table can provide sufficient displacement space for the displacement of the main shaft, ensure the displacement stability of the main shaft when assembling the bearing, and avoid the bearing being pushed open during assembly, resulting in failure to assemble in place.
[0017] In one embodiment of the present invention, a guide arc surface is provided at the end of the bearing positioning plate connected to the feeding plate.
[0018] To implement the above technical solution, the setting of the guide arc surface can provide guidance for conveying the bearing to the interval space between the bearing plate and the base.
[0019] In one embodiment of the present invention, the side of the feeding plate close to the bearing plate is the lowest end.
[0020] To implement the above technical solution, the gravity characteristics of the bearing itself are utilized to enable the bearing to slide into the interval space between the bearing plate and the base.
[0021] In an embodiment of the present invention, a rotor groove and a bearing groove are provided in the rotor seat to carry the rotor and the bearing respectively.
[0022] To implement the above technical solution, by providing a rotor groove and a bearing groove to carry the rotor and the bearing respectively, the positioning of the rotor during assembly can be facilitated, and the tediousness of manual re-positioning can be avoided, thereby improving assembly efficiency.
[0023] In an embodiment of the present invention, the fixed end of the assembly driving member is detachably assembled on the inner side of the base.
[0024] The above technical solution is implemented to facilitate the adjustment of the position of the assembly drive component, thereby meeting the requirements for bearing assembly.
[0025] In an embodiment of the present invention, a support rod is provided between the bearing plate and the base.
[0026] By implementing the above technical solution, the support rod can ensure the connection stability between the bearing plate and the base.
[0027] As described above, a rotor rear bearing assembly tool of the utility model has the following beneficial effects: the base and the bearing plate cooperate with each other, the bearing is placed on the bearing plate, and the base carries the rotor, so that positioning structures can be formed for the rotor and the bearing respectively, thereby avoiding the tediousness of manual positioning, and a rotor seat is provided at the movable end of the assembly drive member, and the bearing positioning plate is set as a V-shaped positioning plate, which can facilitate the loading of the bearings. A large number of bearings can form a conical material pile in the space between the bearing positioning plate and the bearing plate, and the width between the bearing positioning plate and the bearing plate only accommodates the width of one bearing, so that the bearing at the bottom between the bearing positioning plate and the bearing plate can always be kept single, thereby ensuring the continuity of the bearing installation.
