A kind of motor end cover and motor

Abstract

The invention relates to the technical field of electric motors, in particular to a motor end cover and a motor. The motor end cover in the present invention includes a base body, a fixing pin and a knocking plate; plate; the side of the convex plate is provided with a vertical groove; the upper end of the base is provided with two No. 1 threaded holes; the No. 1 threaded holes are symmetrically arranged, and the No. 1 threaded holes are internally threaded to connect the fixing pin; the fixing One end of the pin is welded with a hex nut, and the middle part of the fixed pin is provided with two No. 1 grooves; the No. 1 grooves are symmetrically arranged, and the pressure plate is slidably connected in the No. 1 groove, and the No. 1 spring is also arranged in the No. 1 groove A kind of motor end cover and the motor end cover in the motor according to the present invention push the knocking plate against the pressure plate through the No. 2 spring and cooperate with the knocking plate after the knocking plate is vibrated, so that the motor end cover is in the working state of the motor. There will be no looseness during the operation, thereby improving the practicability and safety of the motor end cover.

[0002] Electric motor is a device that converts electric energy into mechanical energy. In machinery, metallurgy, petroleum, coal, chemical, aviation, transportation, agriculture and other industries, electric motors are widely used; with the continuous improvement of industrial automation, it is necessary to adopt Various control motors are used as components of automation systems, and motors are also indispensable in the automatic control system of artificial satellites; in addition, motors are more and more widely used in national defense, culture, education, medical treatment and daily life; existing When the motor is working, it will generate a large amount of vibration force, which will cause the end cover and the fixing parts on the end cover to loosen or disengage, thus causing potential safety hazards. Security is also greatly enhanced

[0003] There are also some technical solutions about the motor end cover and the motor in the prior art. For example, a patent with the application number CN201610413202.8 discloses a motor end cover. The technical solution includes a circular end cover body and a motor body , the circular end cover body includes an inner cover body and an outer cover body, the inner cover body and the outer cover body are fixed by connecting pieces on the inner wall of the outer cover body, a gas cavity is provided between the inner cover body and the outer cover body, and the inner cover body The edge of the body and the outer cover is also provided with a connecting cavity for inserting into the motor body. The outer cover is provided with a number of thread holes, and the inner wall of the inner cover is provided with screw grooves corresponding to the thread holes. The screws pass through the outer cover. The body and the motor body are fixed with the screw slots of the inner cover body, the outer cover body is provided with a junction box, and the junction box is provided with circuit boards and wiring cables. This technical scheme connects the outer cover body, motor body and inner cover body through screws. It is fixed as a whole to prevent the motor vibration from causing the threaded end cap to loosen or fall off, resulting in safety accidents; however, the vibration of the motor in this technical solution can still drive the screws to shake and fall off, thereby causing potential safety hazards, which in turn led to the failure of the solution. limitation
