Embodiment Construction

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] see figure 1 As shown, a new energy electric vehicle motor inner casing processing technology, the motor inner casing includes a blank metal tube 1, the raw material of the blank metal tube 1 is aluminum profile pipe material of Φ312mm*3000mm, the blank One end of the metal pipe 1 is provided with a positioning reference ring 2, and the outer surface of the blank metal pipe 1 is provided with a spiral channel 3;

[0032] The processing technology of the inner casing of the motor specifically includes the following steps:

[0033] Step 1. Use a double-column band sawing machine to saw the material to make a blank metal tube 1. Before sawing the material, identify the direction and mark the workpiece with a large right angle with a paint pen; the total length of the blank metal tube 1 is 362mm±0.5mm, and ensure that The perpen...

Abstract

The invention discloses a machining process of an inner shell of a motor of a new energy electric vehicle. The process comprises the steps that (1) a double-pillar band mill is used for sawing materials and a metal pipe blank is made; (2) an inner hole of the metal pipe blank is commonly turned and back supported, and the outer circle surface of the metal pipe blank is roughly turned; (3) one end of the metal pipe blank is machined, and a positioning base ring is turned out; (4) the outer circle surface of the metal pipe blank is machined, and a spiral water channel is turned out; (5) the inner hole and the outer circle surface of the metal pipe blank are machined in a variable-speed and material stress releasing machining mode; (6) a mounting and positioning pin hole is machined in a rapid clamping and positioning mode adopting pneumatic back supporting of the inner hole; and (7) after a finished product is obtained, burrs and seamed edges generated during machining are cleaned up through a handhold side scraper. The defects that a traditional horizontal type numerically controlled lathe has defectiveness caused by dead load of products and clamping deformation and the alignment and clamping time is long are overcome; and the traditional process is improved, the machining procedures are reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of processing the inner shell of the motor of a new energy electric vehicle, in particular, it relates to a processing technology of shell parts with a relatively large cylindrical shape and a spiral water channel in this field, and is applicable to all approximate sizes and shapes. The processing of the inner casing of the motor. Background technique [0002] New energy electric vehicles have been widely promoted, and the quality of one of the core motor components has also attracted much attention and attention. Whether a motor with good performance can be produced depends first on whether the inner shell of the manufactured motor has good performance, and the rationality of the processing technology plays a decisive role. [0003] Parts such as the inner shell of the motor have the characteristics of thin wall, high material removal rate, easy deformation and difficult processing, high precision, high value and no...
