Description
Technical field
The utility model relates to a kind of dockboard swing arm drive device.
Background technology
In current floor, furniture-plates veneering production line, the mode that loader swing arm clamp drives assembling device to adopt has motor push rod type, hydraulic push rod type, air-leg formula. Motor push rod type adopts the servomotor involving great expense to coordinate ball-screw to realize the rotation and the location that promote swing arm, and because of variation and the impact of load, the service life of electric pushrod is shorter, and use cost is high does not look forward to. Although hydraulic push rod is exerted oneself greatly, must be equipped with extra hydraulic system, for passing through the high electromagnetic servo valve control of price in the accurate location of realizing push rod position, simultaneously very high to the environmental requirement of hydraulic system. Air-leg low cost but cannot meet the operating mode of multistation and varying load, limits its scope of application greatly.
Summary of the invention
The utility model provides a kind of dockboard swing arm drive device.
For achieving the above object, the technical solution adopted in the utility model is: a kind of dockboard swing arm drive device, comprise connecting rod and at least two dockboard swing arms, in described dockboard swing arm, be fixed with dockboard swing arm driving arm, and described dockboard swing arm becomes angle setting with dockboard swing arm driving arm, described dockboard swing arm rotational support is in a vertical dockboard swing arm rotating shaft arranging; One side of described dockboard swing arm is provided with the connecting rod moving back and forth, described dockboard swing arm driving arm and described connecting rod pivot joint; Described connecting rod and one moves back and forth driving mechanism driving and is connected.
Preferred technical scheme is: described in move back and forth driving mechanism and comprise an eccentric stiffener.
Preferred technical scheme is: described in move back and forth driving mechanism and comprise variable-frequency motor, reductor, the output shaft of described variable-frequency motor and the power shaft of reductor are in transmission connection, the driving shaft of described reductor and the power shaft of described eccentric stiffener are in transmission connection, the output shaft of described eccentric stiffener and described connecting rod pivot joint.
Preferred technical scheme is: the both sides of described connecting rod are provided with position-limit mechanism.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Dockboard swing arm drive device of the present utility model directly drives driving shaft, rotates by the swing arm of synchronising (connecting) rod driving mechanical, avoids connection mechanism between common leading screw, hydraulic oil or compressed air, ensures the precision of transmission, and its angle precision can reach ± and 0.06 °. Have advantages of that driving is direct, precision is high.

Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the present invention without essence.
Embodiment: dockboard swing arm drive device
Shown in accompanying drawing 1 and accompanying drawing 2, dockboard swing arm drive device, comprises connecting rod 5 and two dockboard swing arms 6. The quantity of dockboard swing arm 6 arranges according to specific needs, can be more than three or three.
In described dockboard swing arm 6, be fixed with dockboard swing arm driving arm 7, and 7 one-tenth angle settings of described dockboard swing arm 6 and dockboard swing arm driving arm, described dockboard swing arm 6 rotational support are in the dockboard swing arm rotating shaft 9 of vertical setting, and dockboard swing arm rotating shaft 9 is fixed on installs on table top 8. One side of described dockboard swing arm 6 is provided with the connecting rod 5 moving back and forth, described dockboard swing arm driving arm 7 and described connecting rod 5 pivot joints; Described connecting rod 5 and one moves back and forth driving mechanism driving and is connected.
Preferred: described in move back and forth driving mechanism and comprise an eccentric stiffener. This eccentric stiffener can be toggle or eccentric shaft mechanism.
Preferred: described in move back and forth variable-frequency motor 2, the reductor 3 that driving mechanism comprises controller 1, attached encoder, the power shaft of the output shaft of described variable-frequency motor 2 and reductor 3 is in transmission connection, the driving shaft 4 of described reductor 3 is in transmission connection with the power shaft of described eccentric stiffener, the output shaft of described eccentric stiffener and 5 pivot joints of described connecting rod.
Preferred: the both sides of described connecting rod 5 are provided with position-limit mechanism.
