The invention discloses a practical training platform for installation, adjustment and maintenance of an electric drive system. The practical training platform comprises a power supply system, a drive motor assembly, a fault setting and detecting system, a disassembly and assembly mechanism and a control system, the driving motor assembly is used for simulating power driving of a vehicle and providing a detection source of the practical training platform; the fault setting and detecting system is used for manually setting faults so as to simulate faults of a vehicle and can measure circuit parameters of the system; the control system comprises a control switch, a motor controller and upper computer software installed in a touch screen. According to the invention, the functions of adjustment, maintenance, teaching and examination of the new energy automobile electric driving system can be realized, students can deeply understand the control principle of the electric driving system, and the capabilities of disassembly, assembly and debugging of the electric driving system, detection and maintenance of the electric driving system, insulation test and air tightness test of the electric driving system and the like can be improved.

This invention relates to the field of steel plate welding technology, specifically to a steel plate butt welding device, including a base and a processing table, as well as a welding mechanism, a heating mechanism, a beveling mechanism, and a splicing mechanism. The splicing mechanism includes a drive assembly, two feeding plates, and two clamping assemblies. The beveling mechanism includes a bidirectional electric push rod, a position adjustment assembly, two grinding discs, and two swinging assemblies. A support column is fixedly provided on the top of the base. The heating mechanism includes a telescopic assembly, a first sliding assembly, and four electric heating plates. The welding mechanism includes a welding torch, a second sliding assembly, and two traction assemblies. This steel plate butt welding device of the present invention prevents visual errors caused by manual beveling based solely on experience, improves the adjustment accuracy of the grinding disc tilt angle, further improves the beveling accuracy, ensures the uniformity of the beveling of the two steel plates, and prevents problems such as incomplete penetration, welding deformation, and undercut, thereby improving the butt welding effect of the two steel plates.
