The vertical chute is set, extends toward cylindric center through support end that radian is arranged is consistent with knife bar outer diameter in the vertical card slot
Curved tablet, curved tablet mutually fastens and fixes knife bar；In column, column inner wall is by screw thread in conjunction with adjusting knob
And adjustable spring is placed between support end and adjusting knob.
Further, curved tablet is semicircle, and bilateral symmetry, two mutually fasten and can become a common circumferential
A part and knife bar is fixed；The radial width of tabletting is set as all or part of covering knife bar chuck from top to bottom and can limit
Knife bar processed it is vertically movable.
Further, screw thread is arranged in a part of inner wall that column accommodates adjustable spring, and flexible bullet is arranged in the top of support end
Spring, column inner wall is by screw thread in conjunction with adjusting knob.
Further, boss is provided at circumferentially spaced with column sliding groove, and boss be located at two-by-two it is same diametrically.
Further, boss carries out knife bar in conjunction with the card slot in the knife bar chuck outside wall surface of knife bar circumferentially positioned.
Further, the fixed milling cutter of the top center of knife bar.
The milling machine cutter bar clamping device that the utility model is implemented preferably is made of 45# steel.Device noumenon passes through bottom screw
Secure the device to desktop, knife bar by monosymmetric card slot by knife bar card master, by knob come the height of adjustment spring to
Fix clamp device will in the middle part of knife bar, knife bar will all be fixed up and down, when milling cutter is changed or loaded onto from knife bar, use
Uniform force when spanner fastens avoids leading to screw thread stripped thread because force is excessive.
Clamp device passes through spring press on the threaded fastener in the middle part of knife bar, to prevent from preventing in rundown process
Stripped thread caused by knife bar play.Different knife bars is adapted to using adjustable spring, it can be according to the height of different knife bar screw threads
The appropriate height for adjusting adjustable spring of degree.
Compared with the existing technology, the utility model has the following beneficial effects:
Since knife bar is fixed by tabletting, uniform force when being fastened when fixed cutting tool is to guide rod with spanner, avoid because
Exerting a force excessive leads to screw thread stripped thread.
Greatly convenient and simplified milling cutter is installed to program and process on knife bar, improves work efficiency.
The height of adjustable spring can be suitably adjusted according to the height of different knife bar screw threads.Applicability is wide.
