TECHNICAL FIELD
[0001] The utility model relates to motor production technical field especially relates to an easy-to-dismount injection molding end cover. BACKGROUND
[0002] At present, motor tends to be highly integrated, and the two-in-one situation with speed reducer often occurs, and the motor often shares the end cover with the speed reducer during the design of high integration, which leads to that the motor cannot be subjected to factory inspection and lacks protection during transportation because of lacking the front end cover. The current common practice is to make an iron false end cover, install it and then perform factory inspection, and then remove the false end cover after completion, which affects the inspection efficiency and there is a risk of damaging parts during the removal process. After the removal of the false end cover, the paint spraying process needs to be protected again, which affects the efficiency. Without the end cover protection, the motor stator and rotor are easy to rub against each other or foreign matter falls into the motor during transportation. SUMMARY
[0003] In order to solve the problems of the two-in-one motor with the speed reducer in the prior art, such as increasing production cost of the false end cover, affecting inspection efficiency, etc., the utility model provides an easy-to-dismount injection molding end cover.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:
[0005] An easy-to-dismount injection molding end cover comprises two semicircular splicing plates integrally injection molded, the middle of the splicing plate is a bearing chamber extending outward, which is used for cooperating with the front bearing of the motor to perform radial positioning; the upper and lower sides of the bearing chamber are respectively provided with a female buckle and a male buckle, and the female buckle and the male buckle on the two splicing plates are buckled with each other; the front end of the bearing chamber is a stop edge, which is used for paint spraying protection and preventing foreign matter from falling into the motor; the edge of the splicing plate is uniformly distributed with a plurality of mounting holes in the circumferential direction, which is used for mounting the splicing plate to the motor base.
[0006] Preferably, the rear side of the bearing chamber is provided with a stop opening, which is used for cooperating with the motor base stop opening to perform radial positioning.
[0007] Preferably, the outer side of the bearing chamber is uniformly distributed with a plurality of reinforcing ribs in the circumferential direction, which is used for strengthening the structural strength.
[0008] Compared with the prior art, the utility model has the beneficial effects that: the utility model can be conveniently installed on the motor, so that the motor can be subjected to factory inspection, and after the completion of factory inspection, the utility model is not immediately removed, which effectively protects the subsequent paint spraying and transportation process of the motor. When delivered to the customer installation site, the utility model is removed, and since it is a splicing structure, the removal is very convenient. The whole is integrally injection molded, which is low in cost and suitable for large quantities. BRIEF DESCRIPTION OF DRAWINGS

[0012] In the drawing: 1, splicing plate, 2, female buckle, 3, male buckle, 4, stop, 5, baffle, 6, bearing chamber, 7, mounting hole, 8, reinforcing rib. Specific implementation
[0013] In the description of the present utility model, it is understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal" and the like is the orientation or position relationship based on the drawing shown, and is only for the convenience of describing the present utility model and simplifying the description, and therefore cannot be understood as a limitation on the present utility model.
[0014] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.
[0015] As Figures 1-3 shown, the embodiment of the present utility model comprises two semicircular splicing plates 1 integrally injection molded, the middle of the splicing plate 1 is a bearing chamber 6 extending outwardly, which is used for cooperating with the front bearing of the motor to perform radial positioning; the upper and lower sides of the bearing chamber 6 are respectively provided with a female buckle 2 and a male buckle 3, and the female buckle 2 and the male buckle 3 on the two splicing plates 1 are buckled with each other; the front end of the bearing chamber 6 is a baffle 5, which is used for paint protection and preventing foreign matters from falling into the motor; the edge of the splicing plate 1 is uniformly distributed with a plurality of mounting holes 7 along the circumference, which is used for mounting the splicing plate 1 to the motor base.
[0016] As a preferred, the rear side of the bearing chamber 6 is provided with a stop 4, which is used for cooperating with the stop of the motor base to perform radial positioning.
[0017] As a preferred, the outer side of the bearing chamber 6 is uniformly distributed with a plurality of reinforcing ribs 8 along the circumference, which is used for strengthening the structural strength.
[0018] When used, two same assembling plates 1 are assembled by concave buckle 2 and convex buckle 3 to form an integral end cover, and then installed on the motor, bearing chamber 6 is matched with the motor bearing, stopper 4 is matched with the motor base, and the end cover is connected with the motor base through mounting hole 7 by bolts. At this time, the motor rotor has been supported, and the motor can be idled for factory inspection. During transportation, the motor stator and rotor do not directly contact, which can effectively avoid the friction between the motor stator and rotor. The stop edge 5 just blocks the front bearing of the motor, which can protect the bearing when the motor is painted and transported. When the customer needs to install the motor, the bolts connected with the motor base through the mounting hole 7 are removed, and the assembled end cover can be easily disassembled and removed in blocks.
[0019] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
