Abstract
Description
Technical Field
[0001] This utility model relates to the field of end cap technology, and in particular to a high-precision end cap that is easy to position quickly. Background Technology
[0002] An electric motor is a general term for devices that convert mechanical energy into electrical energy. Most electric motors operate on the principle of electromagnetic induction. In reality, in order to protect the motor, an end cover is often installed on it. This end cover can prevent external forces from damaging the motor and can also prevent dust and moisture. However, during the operation of the motor, the end cover is very easy to loosen. This not only fails to protect the motor but may even cause certain dangers.
[0003] In view of the above, it is necessary to improve the existing end cover structure to adapt it to the current needs of motor operation. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a high-precision end cover that is easy to position quickly, including a cover body, a mounting plate disposed on the outside of the cover body, and positioning plates symmetrically disposed on both sides of the mounting plate. The positioning plates are provided with mounting holes for fixing the motor and assembly after assembly, and fixing holes for fixing the end cover and the housing after assembly. A first bearing hole is provided in the middle of the cover body.
[0005] As a further supplement to this technical solution, the upper and lower sides of the cover are provided with sealing grooves for installing sealing rings, and the mounting plate is located in the middle of the cover.
[0006] As a further supplement to this technical solution, the outer circumferential diameter of the cover is smaller than the diameter of the mounting plate.
[0007] As a further addition to this technical solution, the upper and lower surfaces of the cover protrude from the surface of the mounting plate.
[0008] As a further supplement to this technical solution, the cover body is also provided with an exhaust hole.
[0009] As a further supplement to this technical solution, the cover body is provided with a plurality of reinforcing ribs arranged in an array in the circumferential direction outside the bearing hole, and the reinforcing ribs are fixedly installed on the housing.
[0010] As a further supplement to this technical solution, the positioning plate is provided with positioning holes.
[0011] Its beneficial effects are that it has a good connection and positioning effect with the main body of the housing, assembly and motor, is easy to install, and has an exhaust hole to facilitate the discharge of gas when the motor is running, which can further improve the sealing performance of the motor.

[0016] To facilitate a clearer understanding of this technical solution for those skilled in the art, the following will be described in conjunction with the appendix. Figure 1 -3. A detailed description of the technical solution of this utility model:
[0017] A high-precision end cap for easy and rapid positioning includes a cover body 1, a mounting plate 2 disposed on the outside of the cover body 1, and positioning plates 3 symmetrically disposed on both sides of the mounting plate 2. The positioning plates 3 are provided with mounting holes 4 for fixing the motor and assembly after assembly, and the size is M8 thread. The positioning plates 3 are provided with fixing holes 5 for fixing the end cap and the housing after assembly, and the size is M5 screw through holes. The cover body 1 is provided with a first bearing hole 6 in the middle for assembling and fixing the bearing.
[0018] The cover 1 is provided with sealing grooves 7 on the upper and lower sides for installing sealing rings to improve the sealing performance of the motor; the mounting plate 2 is longitudinally arranged in the middle of the cover 1.
[0019] The outer circumferential diameter of the cover 1 is smaller than the diameter of the mounting plate 2. Furthermore, the upper and lower surfaces of the cover 1 protrude from the surface of the mounting plate 2, and a gap is left between the mounting plate 2 and the cover 1. A bearing is installed on the outer side of the cover 1 and on the mounting plate 2 for concentric connection with the main body of the casing to ensure the concentricity of the bearings at both ends.
[0020] The cover 1 is also equipped with an exhaust port 8 for the discharge of gas when the motor is running.
[0021] The cover 1 has several reinforcing ribs 9 arranged in an array around the bearing hole, and the reinforcing ribs 9 are fixedly installed on the shell and have high strength.
[0022] The positioning plate 3 is provided with a positioning hole 10, which has a diameter of 3cm, for angular positioning during assembly.
[0023] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
