Utility model content
For above defect or the Improvement requirement of prior art, the utility model provides a kind of syndeton for connecting knife bar and cutter-exchange mechanism, it is by being optimized design to the syndeton of cutter-exchange mechanism and knife bar, by taper fit and in conjunction with positive/negative thread connect, can realize being connected quiveringly the gapless of knife bar with cutter-exchange mechanism fast demountable.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of syndeton for connecting knife bar and cutter-exchange mechanism, to realize being fastenedly connected of knife bar and cutter-exchange mechanism, it is characterized in that, this syndeton comprises connecting ring, this connecting ring is hollow barrel-type, the internal face at both ends is provided with two sections of screw threads that rotation direction is contrary, one of them of the end that described knife bar is connected with cutter-exchange mechanism arranges the axis of cone and another arranges taper hole, both realize taper fit at socket, and one of them link end outer peripheral face arranges screw thread, another this link end outer peripheral face correspondence arranges the contrary screw thread of rotation direction, two link outer peripheral faces after described connecting ring is enclosed within above-mentioned taper fit are also connected with the screw thread difference corresponding matching of described two link end outer peripheral faces by two sections of screw threads that wherein rotation direction is contrary, realize the connection locking to knife bar and cutter-exchange mechanism.
As improvement of the present utility model, the tapering of described taper fit is the Small Taper cooperation of 1:80-1:200.
As improvement of the present utility model, the Small Taper of described taper fit to be ratio be 1:100 coordinates.
As improvement of the present utility model, described connecting ring periphery wall is provided with groove, for mating with spanner for be screwed connecting ring by spanner or unclamp.
In the utility model, two connectors design identical 1:100 Small Taper taper hole respectively and the axis of cone coordinates, and this taper fit can realize the connection self-locking of two connectors.Connecting ring is the key component that two connectors connect.The mode that connecting ring preferably adopts internal thread to connect.Internal thread is designed to one section of plus thread, and one section of left-hand thread, is connected with two connectors respectively.Screw for convenience of screw thread, can arrange spanner, during use, catch on connecting ring upper ejector lever groove carry out rotation fastening nut with spanner, two connector tensions connected, if need to unclamp connection, available spanner reversely rotates, and can unclamp the connection of two connectors.
In general, the above technical scheme conceived by the utility model compared with prior art, has following beneficial effect:
(1) link of knife bar and cutter-exchange mechanism is set to axis hole and the axis of cone by structure of the present utility model respectively, coordinates the ground floor gapless that can realize knife bar and cutter-exchange mechanism to be fastenedly connected by adopting Small Taper.
(2) structure of the present utility model arranges the connecting ring with the screw thread of positive and negative two rotation directions at two links, connect to mate with the two ends screw thread of corresponding positive and negative two rotation directions of two link outer peripheral faces respectively, the gapless that can realize knife bar and cutter-exchange mechanism is further fastenedly connected, realize to two kinds fastening by the rotation in a direction that the rotation in another direction realizes unclamping simultaneously, simple to operation.
(3) this structural safety of structure of the present utility model, reliable, easy to use, can realize that the gapless of knife bar and cutter-exchange mechanism is vibrationless to be reliably fastenedly connected.
