Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a magnetic pole core drilling and tapping clamp. Background Art

[0002] The pole core is a material used to manufacture the rotor core of a permanent magnet synchronous motor. The pole core has two structures: solid and laminated. The solid pole is made of forged steel or cast steel. It has the characteristics of high mechanical strength, good damping performance, large asynchronous starting torque, and large pole shoe surface loss. It is often used in high-speed hydroelectric generators. The laminated pole is made of 1 to 1.5 mm thick steel plate punching sheets, riveted or tightened into a whole with rivets. Therefore, it is necessary to use a punching machine to open holes in it, and use a tapping head to perform thread processing, so as to facilitate the use of bolts for fixed installation and connection. Before processing, the existing pole core needs to be manually screwed to press and fix the core, so as to perform drilling operations. The efficiency is low and the core is easy to loosen during long-term vibration. At the same time, the current fixture can only hold one core workpiece, which is not very practical.
