A kind of processing method of motor, motor casing and motor casing

Abstract

The invention relates to a motor casing. Radiation ribs and a spigot matched with an end cover of the motor are processed on the motor casing, and the thickness of a wall between the bottom of a groove formed by two adjacent radiation ribs and the inner wall of the spigot is not smaller than 3 mm. The thickness of the wall between the bottom of the groove formed by two adjacent radiation ribs and the inner wall of the spigot is not smaller than 3 mm, that is, the periphery of the spigot position guarantees relatively ideal wall thickness, accordingly, the strength of the spigot position is improved, deformation of the position in the spigot processing process is effectively reduced, and the accuracy of the motor is guaranteed. The invention further discloses a processing method of the motor casing and the motor adopting the motor casing.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment production, in particular to a motor, a motor casing and a processing method for the motor casing. Background technique [0002] With the development of society, motors have been widely used in all aspects of people's production and life, and the miniaturization and intelligence of electrical appliances have driven motors to continue to develop towards miniaturization and intelligence. [0003] The miniaturized motor requires high precision in the production process, and it is necessary to strictly limit the deformation of the casing during the production process. Taking the servo motor as an example, the mass-produced servo motor casing 01 is made of aluminum alloy, and the blank of the casing is extruded from the inner cavity of the mold through extrusion molding and cut according to the length, such as figure 1 As shown in , and then use the machining method to process the ...

AI Technical Summary

Problems solved by technology

[0004] The position of the mouth of the casing needs to be matched with the motor end cover 02, such as figure 1 , figure 2 and image 3 As shown in , the screw 021 needs to be placed in the hole of the motor end cover 02 when assembling the servo motor and the reducer. large gap, that is image 3 In L1, this requires the diameter of the outer wall of the casing 01 to be reduced, and for a certain type of motor, the inner diameter and the diameter of the spigot of the casing 01 are generally determined, which leads to a change in the location of the spigot of the casing 01. The wall thickness L2 is very small, and the position of the mouth of the casing is very easy to deform during the processing, thereby affecting the accuracy of the motor; and the outer wall of the casing 01 is also provided with cooling ribs 011, and the gap between two adjacent cooling ribs 011 Grooves further exacerbate deformation
