Bonding method of strong motor magnetic tile and shell
Mar 12, 2018

Strong motor magnetic tile and motor casings are bonded, which will also apply the water to the tile surface of the net of the massager motor magnets. After that, the magnets will be loaded into the hole of the motor casing and bonded. In this process, because the strong motor magnetic tile itself is magnetic, it is easy for the magnetic tile to be adsorbed on the inner wall of the casing and slide into a designated position, thus causing the contact between the strong motor magnetic tile and the inner wall of the motor casing less than a specified position. At this time, the loss of glue on the surface of the magnetic tile can also be caused, and the phenomenon of plastic scraping of the magnetic shoe of the motor vehicle occurs.

 

The consequences of the scraping of the magnets in the strong motor magnetic tiles are due to the uncontrollable amount of adhesive glue and the amount of glue that is less than expected. This will also result in insufficient bond strength. In order to avoid the phenomenon of plastic scraping of the magnetic shrapnel, it is necessary to pay attention to designing a tool to bond the magnetic tile. The principle of the tooling is based on a 2-jaw chuck or a 4-jaw chuck, which is determined according to the pole pair number of the motor.

 

Install fixtures on the chucks of the chucks to fix the fixtures. The fixtures that hold the magnets are cylindrical. The outer arc of the cylinder and the arc of the magnets are consistent to ensure that the magnets of the strong motor can fit tightly outside the cylinder. surface. The height of the cylinder is determined based on the height of the stator of the motor and the position of the magnet and the casing.

 

Afterwards, in order to avoid the phenomenon of plastic scraping of the strong motor magnetic tile, it is necessary to pay attention to the fact that it is necessary to perform 2 or 4 equal divisions on the cylinder according to the pole pair of the motor, leaving an axial fixation at the end of each aliquot. In the case of a magnetic shoe, the peripheral edge of the magnetic shoe should be fixed at each edge of each aliquot. Control of the tightening torque of the chuck through a controllable torque wrench directly controls the magnetic shoe and the housing. The pressure between them will then be able to guarantee the consistency of the bonding effect of each pole magnet.

 

The manufacture of the stator assembly in the DC motor manufacturing process is an important process. The stator assembly is a kind of strong motor magnetic tile assembly. As mentioned above, the assembly of the magnetic shoe joints of the fitness equipment to the motor housing is a strong component. When the motor magnets are bonded, the magnets are first magnetized and then bonded to the top of the casing to avoid the phenomenon of squeegeeing. It is necessary to design a new bonding jig to reduce the loss of glue. Increase the strength of the bond.
