Mainly there is following shortcoming in prior art: intermittent type rotates and multi-direction straight line motion interlock difficulty, and the linking mechanism complex structure is bulky; One can only be rotatablely moved and be converted to a straight line motion, can't directly be converted to the straight line motion of a plurality of directions; The manufacture cost height; Need a plurality of motors if will obtain a plurality of straight line motions, control is complicated, and trouble is installed.
The model utility content
At above-mentioned the deficiencies in the prior art part, the purpose of this utility model just provides a kind of intermittent type of realizing synchronously and rotates the linking mechanism that moves with multi-direction synchronous linear, can solve the problem that above-mentioned prior art exists fully.
The purpose of this utility model realizes by following technical proposals:
A kind of linking mechanism, comprise belt wheel, tumbler shaft, intermittent type rotating mechanism, interior axle, outer shaft, cam disk, gear one, gear two, one end of tumbler shaft is installed belt wheel, the other end is installed gear one, outer shaft is the cylindrical drum of both ends open, one end of interior axle is connected with tumbler shaft by the intermittent type rotating mechanism, the other end inserts outer shaft, be connected with outer shaft by bearing, outer shaft one end is installed and gear one meshed gears two, overlapping interlocking of the other end sets firmly some cam disks, and cam follower of assembling constitutes cam mechanism on each cam disk.
As preferably, described gear one has the identical number of teeth with gear two.
As preferably, described intermittent type rotating mechanism is the single armed Geneva mechanism, and the pivoted arm of band straight pin is set on the tumbler shaft, and sheave is installed in going up of interior axle, and pivoted arm cooperates formation single armed Geneva mechanism with sheave.
As preferably, described sheave has 5 radial grooves.
As preferably, described cam disk has 4, between the adjacent cams dish staggered 72 °.
Compared with prior art, the beneficial effects of the utility model are:
Only need a power source just can convert synchronous linear to-and-fro motion on an intermittent type rotational motion and a plurality of direction to.This linking mechanism adopts Purely mechanical mechanism to guarantee that intermittent type rotates and the interlock accuracy of each straight reciprocating motion, control simple and convenient, delicate structure, cost is low.
