This device carries out technological improvement by original lock plunger, cracks the outer wall of original lock plunger axle bed connecting portion outputs 4-6 bar; Original lock plunger spindle nose fixed part increases screw, and screw occupy the center of fixed part, and the other end of screw is communicated with the interior hexagonal fastener hole of axle bed connecting portion; Above-mentioned improvement makes lock plunger inside become an one end with interior hexagonal fastener hole, the hollow-core construction of another end band Hu screw, above-mentioned hollow-core construction has additional conical head bolt in addition, and the also threaded key of conical head bolt matches with screw, is provided with fastener hole in the termination of cone-shaped end one end; It is fixed that described roll shaft is pressed solidly by lock plunger top, and conical head bolt screws locking lock plunger position.
Above-mentioned improvement, original lock plunger is after screwing, the conical head bolt of its inside is utilized to carry out secondary to lock plunger fastening, conical head can make the outer wall of the lock plunger axle bed connecting portion of lock plunger open laterally along cracking, thus the pressure added between screw that lock plunger and axle bed be provided with, add frictional force, lock plunger position is locked, there will not be loosening; Match with above-mentioned improvement, damping roller seat changes full circle, hollow ellipse structure into by semicircular ring structure.
Beneficial effect after improvement: offset printing unit water bucket roller loosens problem and obtains essence solution, and locking device manipulation is convenient, and stable equipment operation significantly improves, and result of use is obviously better than original machine mechanism, and this locking device has great dissemination.
As the further improvement to the technical program, described to crack wide be 0.1-0.2mm.Because lock plunger diameter is less, so it is not easily too large to crack.
As the further improvement to the technical program, described conical head bolt is less than the length of lock plunger, and the diameter of conical head is larger than the diameter of interior hexagonal fastener hole inscribed circle, and after conical head bolt screws, its conical head submerges in interior hexagonal fastener hole.
Conical head carries out secondary extrusion locking to lock plunger, and its conical head submerges in interior hexagonal fastener hole, further can increase the fastness of conical head bolt secondary locking.
As the further improvement to the technical program, described lock plunger is long is 18mm, and the diameter of plush copper is 8mm, and the diameter of screw is 5mm, and the length of screw is 8mm.
As the further improvement to the technical program, described conical head bolt is long is 17mm, and the hypotenuse in conical head cross section and the angle of horizontal plane are 15
0.
As the further improvement to the technical program, described axle bed is the ellipse of hollow, and axle bed is provided with fixing hole in one end of transverse; The other end stationary roller shaft of transverse, roll shaft is provided with the axis hole corresponding to spindle nose fixed part; Lock plunger spinning makes spindle nose fixed part embed axis hole, and conical head bolt is spinning locking lock plunger again.
Axle bed is set to the ellipse of hollow, the hole wall place of fixing hole thickeies, and the length of lock plunger and axle bed threaded engagement increases, and what be threaded is more firm.
