Vertical cnc machining center spindle components are composed of spindles, automatic clamping and releasing mechanisms for tools, front and rear bearings, etc. The front end of the main shaft adopts 7︰24 taper hole, which is easy to install and disassemble the tool holder, and has a critical friction moment. The standard pull stud 5 is tightened in the tool holder. So do you know what is the structure of the spindle component of the CNC vertical machining center? Next, the editor of Xiehe CNC processing factory will give you a brief introduction.

When the tool needs to be clamped, there is no oil pressure in the upper oil chamber of the piston 1, and the spring force of the stacked spring 3 moves the piston 1 upward to the position shown in the figure. The pull rod 2 moves upwards to the position shown in the figure under the pressure of the spring 3, the steel ball 4 is forced to close, and is clamped in the ring groove of the pull stud 5, and the pull stud 5 is pulled upward by the steel ball pull rod, so that the tool shaft tapers The outer tapered surface and the inner tapered surface of the main shaft taper hole are pressed against each other, so that the tool holder is clamped on the main shaft.

When the handle is loosened, the hydraulic oil enters the upper oil chamber of the piston 1, and the oil pressure makes the piston 1 move down, pushing the pull rod 2 to move down. At this moment, the folded spring 3 is compressed, and the steel ball 4 moves downward together with the pull stud 5. When the steel ball moves to the larger place of the main shaft aperture, the pull stud 5 is released, and the tool and the pull stud 5 can be taken off by the manipulator. After the manipulator has loaded the new knife handle, the hydraulic oil in the oil chamber on the piston 1 releases the pressure to tighten the knife handle.

The clamping mechanism of the knife handle is clamped by spring and released by hydraulic pressure, which can ensure that the knife rod will not loosen by itself in case of a sudden power failure during work. ?The upper end of the piston rod hole is connected with compressed air. When the manipulator removes the tool from the spindle, the compressed air blows the taper hole of the spindle through the center hole of the piston rod and the pull rod, so that the taper surface of the tool holder is closely attached to the taper hole of the spindle. together to ensure the correct positioning of the tool. Travel switches 7 and 8 are used to send signals for clamping and loosening the knife rod.

The above content is the structure of the spindle components of the cnc vertical machining center, and I hope it can be helpful to everyone. If you want to know more about cnc processing, please call Xiehe cnc processing factory, we will serve you wholeheartedly.
