Embodiment Construction

[0023] The electron beam welding method for an aluminum alloy piston of an automobile air-conditioning compressor provided by the present invention comprises the following steps:

[0024] Step (1): In the atmosphere, install the first batch of aluminum alloy piston components on the fixture;

[0025] Step (2): Entering the first batch of aluminum alloy piston assemblies installed in the atmosphere into the first semi-vacuum chamber; at the same time, installing the second batch of aluminum alloy piston assemblies on the fixture in the atmosphere;

[0026] Step (3): Make the first batch of aluminum alloy piston assemblies entering the first semi-vacuum chamber enter the full vacuum chamber again, and assemble the first batch of aluminum alloy piston assemblies into the first batch through the clamp Aluminum alloy pistons to be welded; at the same time, the second batch of aluminum alloy piston assemblies installed in the atmosphere enters the first semi-vacuum chamber; the vacu...

Abstract

The invention provides an electron beam welding method for an aluminium alloy piston of an automotive air condition compressor. The aluminium alloy piston is installed in air, and then enters a vacuum chamber at twice. The installed aluminium alloy piston enters a semi-vacuum chamber and then enters the vacuum chamber. The aluminium alloy piston is assembled by a special fixture in the vacuum chamber, so that the assembly precision can be ensured. As the assembly is performed in the vacuum chamber, the vacuumizing speed for the vacuum chamber is enabled to be very fast. The electron beam welding is also performed in the vacuum chamber, so that the number of air holes in welding is less, the depth of welding is great, the strength of welding is high, and the quality of welding is good. The welded aluminium alloy piston is demounted by entering the air at twice. In the invention, the special fixture is adopted to assembly two parts of the aluminium alloy piston in the vacuum chamber, so that the vacuumizing operation is easier, and the vacuumizing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of welding, in particular to an electron beam welding method for an aluminum alloy piston of an automobile air-conditioning compressor. Background technique [0002] The aluminum alloy piston of the automobile compressor is organized in two parts, which need to be connected by welding. The current welding method mainly adopts laser welding technology. Laser welding is carried out in the atmosphere, with convenient operation and high welding efficiency. However, due to the strong reflection of the aluminum alloy on the laser, the laser welding depth is not deep enough. For the aluminum alloy piston that requires a large welding depth, it is required to greatly increase the output power of the laser, which is difficult to meet when the output power of the laser is constant. . In addition, laser welding is carried out in the atmosphere, and there are inevitably certain pores in the weld, which will affect the welding ...
