When gap, upper cutter shaft component skew due to unbalance stress can will not occur and show relatively evenly to upper cutter shaft component applied force amount
As, meanwhile, it will not influence the transmission connection of driving motor Yu upper cutter shaft component, do not influence the active rotation of cutter shaft component.
And c-type sliding block and linear guide engaged therewith are all installed in the two sides of two support arms in U-shape nut set mounting plate, so not only
It can be avoided U-shape nut set mounting plate to rotate with the rotation of ball-screw, while the movement of mounting plate can be covered to U-shape nut
It is oriented to, slides c-type sliding block smoothly along linear guide, and under the cooperation of the first voussoir and the second voussoir, between completion side
The adjustment of gap.
It is only covered in U-shape nut and voussoir is set between mounting plate and guide rail mounting plate, cover mounting plate and closure base in U-shape nut
Between be not provided with voussoir, in this way, only guide rail mounting plate can be passed through when U-shape nut set mounting plate drives c-type sliding block to move up and down
Cutter shaft component is mobile in promotion, and closure base mounting plate is unaffected.
3. the utility model using U-shape nut set mounting plate two groups of line slideway auxiliaries are connected, in this way, can not only will in
Center portion position is vacated, so that upper driving motor is connect with upper cutter shaft component, simultaneously, it is only necessary to use a sideshake adjustment motor and rolling
Ballscrew is used cooperatively, and the driving to two groups of line slideway auxiliaries can be realized, and saves cost.
4. limit plate is arranged in the upper and lower section in side plate, the moving range of U-shape nut set mounting plate can be limited in this way, is kept away
Exempt from it to move up apart from excessive, is detached from c-type sliding block with corresponding linear guide, loses sideshake adjustment function.
5. the utility model installs encoder in sideshake adjustment motor side, which can adjust motor by sideshake
Turnning circle and its relationship between the skidding distance of c-type sliding block and the first voussoir and the gradient of the second voussoir calculate
The moving distance of upper cutter shaft component out, to accurately control sideshake adjustment amount.
