AI Technical Summary
During the replacement of the grinding head spindle of the existing tumbling mill, direct impact can cause deformation or damage to the spindle and bushing, and the limited operating space makes disassembly and assembly inconvenient.
The device employs a combination of a rotating push-pull rod, an additional support body, and a movable clamp. By utilizing the principle of a lead screw and nut, linear motion is converted into rotational motion, indirectly transmitting force and avoiding direct force application to the grinding head spindle. The movable clamp holds the pulley to achieve spindle assembly and disassembly.
It effectively protects the grinding head spindle from damage, enables a convenient and quick assembly and disassembly process, and is suitable for various machine tool structures of tumbling grinding machines, improving operational safety and efficiency.
