Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic steel assembly, in particular to a magnetic steel pressing machine. Background Art

[0002] Motors are an indispensable power source in modern industry and daily life, and permanent magnet motors are an important branch. With the improvement of environmental awareness and the improvement of energy crisis, green energy saving has become an important development direction of the motor industry. Permanent magnet motors have broad application prospects in the field of energy conservation and environmental protection due to their high efficiency and low energy consumption.

[0003] Permanent magnet motors usually require permanent magnets (i.e. magnetic steel) to be embedded or attached to the inner wall of the motor housing (as a stator). The magnetic steel is used to generate a magnetic field, which interacts with the coils on the motor rotor to achieve the conversion of electrical energy into mechanical energy. Embedding or attaching the magnetic steel to the inner wall of the motor housing usually requires the use of a magnetic steel press machine instead of manual pressing, which saves time and effort.

[0004] A traditional magnet pressing machine, such as the Chinese patent application No. (CN201510116181.9), discloses a motor rotor magnet installation tool, including a fixed seat 21, and the upper plane of the fixed seat 21 is provided with a positioning protrusion 22 for positioning the workpiece 7. The workpiece 7 is placed on the fixed seat 21 for pressing the magnet. Although the application uses the positioning protrusion 22 to position the workpiece 7 before the magnet is pressed in, in actual use, in order to facilitate the picking up and placement of the workpiece 7, a clearance fit is required between the positioning protrusion 22 and the workpiece 7. This causes a deviation when the workpiece 7 is placed on the positioning protrusion 22. Even a small deviation will cause the magnet to fail to be pressed into the slot of the workpiece 7. In particular, after long-term use, when the surface of the positioning protrusion 22 is worn, this defect will be magnified and needs to be improved. Utility Model Content

[0056] The top knife assembly 50 is used to push the magnetic steel 8 into the stator 7 and to position the stator 7 during installation.

[0057] It can be seen from the present embodiment that the top knife assembly 50 is used for positioning the stator 7 during installation, that is, when the stator 7 is installed, it is adapted to the top knife assembly 50, so as to position the stator 7 during installation, thereby effectively avoiding the situation in which the magnet 8 cannot be pressed into the stator 7 due to deviation in the placement of the stator 7, and the positioning is convenient and efficient.
