[0015] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] like Figure 1-4As shown, an actuator brush motor assembly tool comprises a base 1, which is used to be installed on a workbench. A supporting tool 2 matching with the actuator housing 3 is installed on the base 1. The actuator housing 3 is supported and positioned by the supporting tool 2, thereby ensuring that the manipulator can accurately place the brush motor 4 at a predetermined position in the actuator housing 3. The brush motor 4 can also be placed in the actuator housing 3 first, and then placed as a whole in the supporting tool 2. A positioning pin matching with the connecting hole of the actuator housing 3 is installed on the supporting tool 2 to improve the positioning stability of the actuator housing 3.

[0019] It also includes a press-fitting tool for press-fitting the brush motor 4, the press-fitting tool includes a transmission component matched with the press-fitting drive device, the press-fitting drive device is a press installed on a workbench (not shown in the figure), the transmission component is a press shaft 6 connected to the press, the press shaft 6 can be connected to the press through a coaxial connecting component such as a sleeve, the structure is simple, and the working stability is high. The end of the transmission component is connected to a profiling component matched with the brush motor 4, the profiling component includes a pressing block 5, the length of the pressing block 5 is greater than the length of the housing of the brush motor 4, and the working end of the pressing block 5 is processed with a profiling groove 10 matched with the brush motor 4, so that the brush motor 4 can be subjected to force at multiple points, the press-fitting stability is improved, and the deformation of the brush motor 4 is avoided during the press-fitting process. The profiling groove 10 extends to the end of the pressing block 5. A positioning device that cooperates with the brush motor 4 is installed in the profiling groove 10. In this embodiment, the positioning device includes an anti-skid layer 9 attached to the bottom of the profiling groove 10. The anti-skid layer 9 is made of an elastic material, specifically a polyurethane adhesive layer, which is obtained by brushing and curing. The thickness of the anti-skid layer 9 near the end is greater than the thickness of the anti-skid layer 9 near the middle. The thickness in the middle is 0.8-1.0mm, and the thickness at the end is 1.2-1.5mm. The friction between the profiling groove 10 and the brush motor 4 is increased by the polyurethane adhesive layer to prevent the brush motor 4 from rotating. The stress points of the brush motor 4 can also be increased. Since the end of the brush motor 4 is supported by the end cover, the structural strength is relatively high, and the end of the anti-skid layer 9 is thicker, so that the pressure on the end is greater during the press-fitting process, thereby effectively preventing deformation.

[0020] The press-fitting tool also includes a pressing head 7 that matches the pins of the brush motor 4. The pressing head 7 is connected to the pressing block 5 by bolts, which is convenient for manufacturing. The pins of the brush motor 4 are pressed into the corresponding slots of the actuator housing 3 by the pressing head 7, thereby achieving one-time press-fitting and improving efficiency.

[0021] A magnet 8 matching the brush motor 4 is installed on the pressing block 5, and a mounting hole matching the magnet 8 is processed on the pressing block 5. Before pressing, since the pre-installed height of the brush motor 4 is not fixed, it is impossible to judge whether the pressing block 5 is close to the brush motor 4. The position of the pressing block 5 and the brush motor 4 is judged after contact by detecting the force on the pressing block 5, and the time is short. After installing the magnet 8, when the pressing block 5 is close to the brush motor 4, the force on the pressing block 5 changes significantly. After detecting the pressure change, the press reduces the descending speed, thereby stabilizing the pressing.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
