As the technical scheme of a kind of optimization, described power set include the reductor that servomotor is connected with servo motor transmission；Described speed reducer drive connecting crank.
Owing to have employed technique scheme, compared with prior art, this utility model crank connecting link clamping; reasonable in design; the intermittent movement of cylinder matched moulds is converted into the continuous motion of crank, thus the great impact power produced when reducing cylinder action, reduces vibrations during mould bases matched moulds; make matched moulds steady; rapidly, both sides cylinder is individually stretched out simultaneously and change both sides crank into and be synchronized with the movement, make mould closing precision improve; greatly enhance machine productivity, improve stability.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
Detailed description of the invention
Embodiment:
As it is shown in figure 1, a kind of crank connecting link clamping, including upper mounted plate 10 and bottom plate 12, between upper mounted plate 10 and bottom plate 12, it is provided with the fixing plate 11 of symmetry.Being provided with power set on fixed plate 10, power set are connected with crank mechanism.Described crank mechanism includes some passing sequentially through transmission with 4 cranks 3 being in transmission connection, and crank 3 is connected with jointed gear unit.Described jointed gear unit is in transmission connection side form.Described side form is installed by side form installing plate 8 and is slidably connected between side form installing plate 8 and bottom plate 12.
In the present embodiment, described jointed gear unit includes some groups of Y shape bar linkage structures from top to bottom.Two connecting rod B6 that the Y shape bar linkage structure of described the top includes the connecting rod A5 that is connected with crank gearing and side form is in transmission connection.The end of described connecting rod A5 and two piece connecting rod B6 is linked together by rotating shaft.Two connecting rod B that other Y shape bar linkage structure described includes the connecting rod A7 that is connected with top rotating shaft transmission and side form is in transmission connection.The end axis of described connecting rod A7 and two piece connecting rod B links together.
Described side form installing plate 8 is slidably connected on bottom plate 12 by slide rail 9.The reductor 2 that described power set include servomotor 1 and servomotor 1 is in transmission connection；Described reductor 2 is in transmission connection crank 3.
When work, two crank Timing Belts 4 connect, servomotor 1, reductor 2 drive under, to right rotation, drivening rod A swings, the angle between connecting rod B is made constantly to become big, side form installing plate is promoted (to be retrained by slide rail bottom side form installing plate, and increase by two connecting rods 2, connected by connecting rod 3, so prevent side form installing plate unbalance stress from producing) close up to centre, start matched moulds.Straight down, two connecting rod Bs interconnective with connecting rod A are positioned at level to connecting rod A, and on same straight line.At this moment in mould, pass into pressure-air bottle blowing, mould will be produced outward pressure F after passing into pressure-air, make the trend that mould oriented both sides in left and right are opened.Owing to connecting rod B is positioned at level, on same straight line, and vertical with connecting rod A and crank center line.If when connecting rod B receives External Force Acting drivewheel, at this formation dead point, position, mechanism cannot move, it does not have acts on the component on connecting rod A, both ensure that mould will not separate because of being stressed, and avoids again reductor to be subject to big active force.When bottle blowing completes, crank continues to rotate, and pulls connecting rod B to swing by connecting rod A, pulls side form installing plate to move to both sides, until mould fully opens；When crank turns over peak, continue rotation and enter again matched moulds next time.Such servomotor does not need through accelerating, slowing down, stopping can complete matched moulds and enter matched moulds next time, so that a burn close time shortens 0.3 second, machine runs more steady, thus largely improving productivity ratio, it is ensured that product quality；Extend machine service life.
This utility model crank connecting link clamping; reasonable in design; the intermittent movement of cylinder matched moulds is converted into the continuous motion of crank, thus the great impact power produced when reducing cylinder action, reduces vibrations during mould bases matched moulds; make matched moulds steady; rapidly, both sides cylinder is individually stretched out simultaneously and change both sides crank into and be synchronized with the movement, make mould closing precision improve; greatly enhance machine productivity, improve stability.
This utility model is not limited to above-mentioned preferred implementation, and anyone should learn the structure change made under enlightenment of the present utility model, every have with this utility model same or like like technical scheme, belong to protection domain of the present utility model.
