For realizing above-mentioned purpose of design, described mechanical assembly drum includes a hollow spindle, is provided with one in main shaft inside and has the left and right roller bearing leading screw that revolves symmetrical screw thread;
Along described main shaft excircle and vertical center line, be arranged with lock dog assembly and finger type anti-package device symmetrically;
The bearing pin of roller bearing leading screw is connected by the cylinder slip cap of key with finger type anti-package device, and described lock dog assembly is connected the medial extremity of cylinder slip cap;
Described lock dog assembly comprises the middle cage plate that is set on the main shaft, and the latch segment of cage plate and arranged on left and right sides is formed in being arranged on symmetrically.
Improvements of the present utility model are, described latch segment is formed and is comprised that several are along the evenly distributed latch segment of main shaft excircle, the outer surface of several latch segments maintains an equal level mutually with the outer surface of middle cage plate, and forms barrel shape mechanism sealing, continuous along described main shaft excircle.
As above-mentioned scheme feature, the barrel shape mechanism by latch segment and middle cage plate form has constituted along the binding face of main shaft excircle and vertical center line symmetrical distribution jointly with finger type anti-package device.
Because formed barrel shape mechanism outer surface smoother, therefore in the assembly drum rotation and carry out inner liner and sidewall rubber when fitting, fit comparatively closely between each is material bed, can avoid producing bubble and gap.
Further improvement project is, described middle cage plate, and its two side ends has intilted inclined-plane.Described latch segment, its medial extremity have and the tangent inclined-plane of middle cage plate two side ends.
When ball-screw is rotating, drive 2 latch segments motion to the inside relatively of lock dog assembly by the cylinder slip cap, the inclined-plane that suits mutually by latch segment and middle cage plate, middle cage plate is raised under both sides stepless action power, simultaneously latch segment is along the below of cage plate in the axially moving to of main shaft, and this moment, steel ring was clamped and to median rise.
For improving the axially-movable performance of lock dog assembly, the latch segment of described lock dog assembly is fixedly connected on the fanning strip, and fanning strip is connected the front end of piston bush, and piston bush inside is provided with piston;
The piston bush that latch segment is formed is connected the front end of the cylinder slip cap of described finger type anti-package device.
Also the improvement project that can take is, the piston of described lock dog assembly is the frustum piston, and the conical surface of frustum piston suits mutually with the inner inclined-plane of latch segment.
Be provided with the cannelure that is used to lock steel ring on the top of each latch segment, one glue ring be installed at upside of the ring groove.
And, described in cage plate can be set to several, and circumferentially evenly distributed along main shaft; An inboard fixedly connected limited block of cage plate in each, limited block inside is fixedly linked by spring and guide pillar screw and positioning seat, and positioning seat is connected on the main shaft.
As above content, the advantage that described mechanical assembly drum has be, by the formed sealing barrel shape of the outer surface of latch segment and middle cage plate mechanism, can form the smooth surface of material bed applying, thereby improve the applying quality effectively, also can conveniently add the applying operation in man-hour.
