Abstract

The invention belongs to the technical field of permanent magnet assembly, and relates to a bonding device and method for a base with an annular groove and a permanent magnet, aiming to solve the problems of high cost, low efficiency, and long time consumption in the bonding of the two, including the base, The base is provided with a base with an annular groove, a magnetic repulsion device for releasing the polarity opposite to the permanent magnet, and a lifting and sealing mechanism for contacting the permanent magnet with the groove bottom bonding surface of the base with an annular groove. The magnetic repulsion device consists of Composed of a coil, a power supply and a switch, the coil surrounds the base with an annular groove and is connected to the power supply through a switch. The bonding device generates a magnetic field opposite to the polarity of the permanent magnet through the magnetic repulsion device to produce a repulsive force on the permanent magnet, which can prevent the permanent magnet from causing the permanent The magnet collides with the base, causing chipping and cracks of the permanent magnet, and the current of the coil is disconnected, the bonding device loses its magnetic field, and the permanent magnet and the base with a ring groove are bonded quickly and accurately.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet assembly, and in particular relates to a bonding device and method for a base with an annular groove and a permanent magnet. Background technique [0002] In engineering practice, a permanent magnet with high magnetic properties needs to be bonded in a base with an annular groove. After the base with an annular groove is bonded to the permanent magnet, the gap between the inner diameter of the permanent magnet and the base is very small, about approx. 1mm, and the base with an annular groove is closed except that the permanent magnet end is a hole, and the inner cavity has an annular blind groove, such as figure 1 Shown is the base with annular groove and permanent magnet shape and structure after bonding. [0003] In the prior art, by using a fixing ring, the permanent magnets are first bonded to the fixing ring with adhesive tape, and then manually inserted into a base with an annular ...
