With the rapid development of the domestic automobile industry, the production of automobile engine and transmission testing has changed from relying on foreign testing companies 10 years ago to now being led by domestic companies, which is very relevant to the current situation of the Chinese automobile market and has contributed to the rapid development of the domestic automobile industry. In recent years, Chinese cars have been ahead of the world in the rapid development of electrification, and electric drive technology has become increasingly popular. The manufacturing of the prototype shell is mainly verified by short cycle times and low cost through simple mold sand casting without mold forming preceptors. The speed of global vehicle development has accelerated, the time to market for new vehicles is getting shorter and shorter, and design changes are becoming more frequent. The original pace and methods of test prototype production have not been able to adapt to the new market, resulting in changes in the test prototype production industry, which requires faster and more accurate verification of designs. At present, the prototype casing is mainly used for bench testing, lubrication testing and winter (summer) testing, calibration, and so on. In the process of electric drive research and development, there are three types of shell test production, namely.

A, transparent shell (visible test) 1, transparent shell test of the varieties of classification of all transparent shell, divided into the whole and splicing of two practices. (1) the general method: the general use of PC, PMMA two kinds of plastic to carve. The advantage is that the general solid, not easy to leakage. The relative cost is also slightly higher. (2) Splicing method: depending on the structure and in order to save costs (material and processing costs), the layers are processed and reinforced with special glues after manual processing. The advantage is that the cost is relatively low. The disadvantage is that oil leakage will occur during the experimental process. 2, transparent sample parts process analysis process analysis → programming → material and tool preparation → rough machining → rough fitting → rough placing (internal stress relief → grinding and polishing → finishing → finishing → secondary polishing → finished product.
Secondly, carved shell A sample (bench test or single road test) 3D electric drive carved shell (aluminum alloy) processing technology, electric drive shell test production of the rapid submission of the shape, the main concern in the selection of materials, internal volume guarantee, internal contour guarantee, key size guarantee assembly point. For the test production of the motor housing in the electric drive, the use of friction stir welding process arises, while the test process of the water jacket inside the motor housing, the guarantee of the dimensions of the water way and the formulation of the inner jacket require attention, involving leakage and flow. 3D etching processing process: process analysis → programming → material and tooling preparation → roughing → blank placement, internal stress relief → finishing → finishing → finished product.
In addition: the inner water jacket of the engine is machined using a four-arm preceptor five-arm machining center for simulated lateral spiral machining.
