Embodiment 1

[0063]In this implementation, when cutting the material, the 45 steel bar stock is selected, which has the following advantages: the surface of the 45 steel bar stock has less oxide layer, and reducing the grinding layer is also conducive to reducing the use of raw materials and reducing production costs; the length of the bar stock used It is 130mm and the diameter is 36mm. When grinding, since there is less oxide layer on the surface of the 45 steel bar, the linear velocity of the abrasive belt during rough grinding is 15m / s, the linear velocity of the abrasive belt during fine grinding is 25m / s, and the feed speed of the workpiece is 2m / min. The total depth is 0.12mm, which can make the surface of the ground bar material free of rust, which meets the requirements of use, and also reduces the grinding time, which is conducive to improving production efficiency; when dipping, spray the bar material with a hot water pipe to preheat The temperature of the bar material reaches 7...

Abstract

The invention discloses a washing machine shaft and a machining method thereof, and belongs to the technical field of shaft machining. The machining method is characterized in that a cold extrusion process is adopted to machine a rod material to enable the rod material to be formed into a stepped shaft, for the stepped shaft obtained after milling and drilling machining, the two end faces are milled, chamfering is performed, and a center hole is punched so that the stepped shaft can be clamped by adopting a double-centre tool method. According to the washing machine shaft and the machining method thereof, through the unified positioning reference, the machining precision is improved, in addition, the production cost is also reduced, the production efficiency is improved, the operation is simple and convenient, the machining quality is stable, and the batch production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of shaft processing, and in particular relates to a washing machine shaft and a processing method thereof. Background technique [0002] The shaft of the washing machine is an important component that supports the drum, transmits power, and completes the laundry function. The shaft of the washing machine has the characteristics of high-speed rotation and torque transmission when it works, and the working environment is harsh, generally with moisture and dust. In addition, both positive and negative rotation , to withstand alternating torque, but also to ensure the accuracy of rotation, in order to reduce noise and achieve the required fatigue limit. Therefore, such parts require high dimensional accuracy and geometric accuracy. There are many existing literatures about the washing machine shaft, for example: Chinese patent number is: 201320752922.9, and the publication date is: Chinese patent document on Ju...
