After fine tuning in place, the pressure holding of 445 pairs of screw pressure holding slots 4411 of relaxation pressure holding, so that pogo pin 442 is in interlocking bar
It is conditioned, is adjusted to and is contradicted after screw 444 touches and shrink a segment length after pogo pin 442, control device in 441
446 triggerings, it is vertical to push away two-way cylinder 42 and reset sliding bottom 41, reset it is vertical push away two-way cylinder 42 after, adjust stop screw 4434,
Until stop screw 4434 and fixed frame 44332 touch, so that vertical push away the two-way closing of cylinder 42, carried out to subsequent workpiece
When processing, telescopicing performance and the position adjusted of stop screw 4434 using pogo pin 442 itself push away two-way gas to vertical
Cylinder 42 limits, and then makes restriction to the processing stroke of sliding bottom 41.
In above-mentioned trim process, after pushing inclined wedge 439 and stop screw 435 to contradict fitting, decelerating motor 432 is closed,
Adjusting inclined wedge 438 is pushing the position on screw rod 436 to fix, and in the case where adjusting inclined wedge 438 and the clamping of reset spring 4301, pushes oblique
Position of the wedge 439 in motion base 433 is fixed, since the inclined-plane taper of inclined wedge is between 1:110 to 1:90, preferably 1:
100, so pushing the moving range of inclined wedge 439 minimum, i.e. promotion inclined wedge 439 adjusts sliding bottom 41 in minimum range
Position further adjusts the position of knife rest 3 in minimum range, after the completion of adjusting, is stretched using the record of control device 446
The collapsing length of contracting probe 442, to determine the vertical reset position for pushing away two-way cylinder 42, to guarantee lathe to high-volume material weight
It is added with the precision of work.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
