Die-casting aluminum part

Abstract

The invention relates to the field of die-casting aluminum pieces, in particular to a die-casting aluminum piece which comprises a motor shell aluminum piece, a motor cover aluminum piece and a motorfoot aluminum piece, and the motor shell aluminum piece, the motor cover aluminum piece and the motor foot aluminum piece are formed in a die-casting mode. The motor shell aluminum piece, the motor cover aluminum piece and the motor foot aluminum piece are formed through die casting. All the components are connected through bolts. A clamping groove is formed in the surface of the second bolt, whena second bolt is completely screwed into a fourth screw hole and a third screw hole, the first bolt is screwed into a first screw hole; the first bolt can be clamped in the clamping groove in the second bolt; when the motor vibrates in use, the second bolt does not rotate under the clamping connection of the first bolt, so that the second bolt can connect the motor cover aluminum piece with the motor shell aluminum piece more tightly, the phenomenon that bolts used for connection between all parts are loosened is effectively avoided, and the motor is safer in use.

Description

technical field [0001] The invention relates to the field of die-casting aluminum parts, in particular to a die-casting aluminum part. Background technique [0002] Die casting is a metal casting process characterized by the application of high pressure to molten metal using the cavity of a mold. Molds are usually machined from stronger alloys, a process somewhat similar to injection molding. Most die castings are ferrous, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. [0003] For the vibration motor casing used on the tamping machine in the high temperature environment, most of them are made of aluminum die-casting. After the die-casting of the motor casing is completed, the parts need to be assembled. The aluminum parts of the casing, the aluminum parts of the motor cover and the aluminum parts of the motor feet are connected. However, after the existing motor casing is assembled and used, the motor will vibrate when it is wo...

Problems solved by technology

[0003] For the vibration motor casing used on the tamping machine under high temperature environment, most of them are made of die-casting aluminum material. After the die-casting of the motor casing is completed, the parts need to be assembled. The aluminum parts of the casing, the aluminum parts of the motor cover and the aluminum parts of the motor feet are connected. However, after the existing motor casing is assembled and used, the motor will vibrate when it is working. The bolts used to connect the parts Loosening will occur, which will cause the motor to be unusable and even cause safety accidents. On the other hand, because the rotor in the motor will generate a lot of heat when it rotates, if the heat cannot be discharged quickly, the motor will be damaged, making the Reduced service life of the motor
