Embodiment Construction
[0034] The permanent magnet assembly device and method of the present invention will be described in detail below with reference to the accompanying drawings.
[0035] figure 1 It is a structural schematic diagram of the permanent magnet pushing fixture of the permanent magnet assembly device of the present invention in a ready state, figure 2 It is a structural schematic diagram of the permanent magnet pushing fixture of the permanent magnet assembly device of the present invention in working state.
[0036] like figure 1 , 2 As shown, the assembly device of the permanent magnet of the present invention includes a permanent magnet push-in fixture, a permanent magnet guide limiter and a permanent magnet push-in pressure bar. The permanent magnet push-in fixture includes a left fixed bracket 5, a right fixed bracket 14, and a rotating shaft 16 and lead screw assembly. The left fixed support 5 and the right fixed support 14 are respectively arranged on the left side and the...

The invention provides an assembling device of a permanent magnet. The assembling device comprises a permanent magnet pushing-in clamp; the permanent magnet pushing-in clamp comprises a left fixed support, a right fixed support, a rotary shaft and a screw rod assembly; the screw rod assembly comprises a screw rod, a slide rod, a sliding push block and a rotating device; and the assembling device of the permanent magnet also comprises a permanent magnet guiding and limiting frame. The invention also provides an assembling method of a permanent magnet by using the assembling device of the permanent magnet. With the assembling device and method of the permanent magnet, the accurate positioning of a permanent magnet unit can be ensured and a strong impact attractive force generated before a permanent magnet unit comes into contact with a magnet yoke of a rotor is also greatly slowed down so that the permanent magnet unit carries out smooth transitions on the magnet yoke of the rotor, the occurrence of a collision phenomenon is reduced, the production safety is ensured, and the qualified rate of a product is greatly increased.
Description
technical field [0001] The invention relates to an assembly device and an assembly method of a permanent magnet, in particular to an assembly device and an assembly method of a permanent magnet suitable for various large and medium-sized permanent magnet devices. Background technique [0002] In recent years, with the improvement of cost performance of sintered NdFeB, SmCo, ferrite and other permanent magnet materials, the development and application of various large and medium permanent magnet devices has entered a new stage. [0003] For most permanent magnet devices, in order to make full use of the magnetic properties of permanent magnets, it is often necessary to install the permanent magnets in the rotor yoke made of soft magnetic materials, and the so-called "magnetic circuit" is formed by the permanent magnets and the rotor yoke. For various large and medium-sized permanent magnet devices, after magnetizing the permanent magnet units one by one, they are assembled to...
