Description

Technical Field

[0001] The invention belongs to the technical field of magnetic pole core processing, and in particular relates to a hole opening tool for processing magnetic pole cores of high-voltage motors. Background Art

[0002] The pole core of a high-voltage motor plays a vital role in the motor. It is a component of the motor pole and together with the field coil constitutes the pole of the electromagnetic motor. The pole core is fixed to the inner wall of the motor housing, and the field coil is mounted on the core. The main function of the pole core is to generate a magnetic field, which is the basic condition for establishing motor rotation. When the motor is powered on, the field coil generates current, which in turn generates a magnetic field in the pole core. This magnetic field interacts with the rotor in the motor, causing the rotor to rotate under the action of force in the magnetic field, thereby completing the energy conversion of magnetic energy, kinetic energy and electrical energy.

[0003] In a high-voltage motor, the pole core is formed by stacking pole core punching sheets. When stacking, the pole core punching sheets are stacked layer by layer on the tie rod. After stacking, the pole core punching sheets are fixed together by the tie rod and nut to form an integral pole core. The pole core of this structure needs to use a hole-opening tool to open holes in the pole core punching sheets, so that the tie rod and nut can fix the pole core punching sheets together. However, the traditional hole-opening tool has shortcomings during use. First, it cannot realize automated batch hole opening, and the hole-opening efficiency is relatively low; second, it cannot form cooling holes while opening holes, and the core punching sheets are tightly stacked together. During the operation of the motor, the cooling medium cannot flow into the interior of the pole core, so that the interior of the pole core cannot be directly cooled, and the cooling effect is poor, which affects the service life.

[0004] In view of this, the inventor hopes to provide a hole-drilling tool for processing the magnetic pole core of a high-voltage motor, which can meet the needs of batch drilling and efficient cooling of the magnetic pole core. Summary of the invention
