Description
Technical field
The present invention relates to a kind of linear reciprocation device, particularly a kind of mechanical linear reciprocating synchronous device.
Background technology
Manipulator often needs to do linear reciprocating motion and operates the product on load-transfer device on a production line, pay-off will keep synchronous feeding with manipulator and load-transfer device simultaneously, conventional is the synchronization action being controlled load-transfer device, manipulator and pay-off by motion controller at present, this kind of synchronous control mode utilizes electronic gear and the electric cam function of motion controller, realize the control to kinematic parameters such as the displacement between each kinematic axis, speed, acceleration/accels, and then realize synchronization action;
There is following shortcoming in this mode:
1. load-carrying capacity is less, and rigidity is lower, and when heavy duty, actuating unit is as delayed or lose step phenomenon in servomotor or stepping motor easily produce, and namely heavily loaded precision is low;
2., when high-speed motion, what be synchronized with the movement is delayed further obvious.Often kind of motion controller has the minimum control cycle characterizing its computing and process and efficiency of algorithm, and when control cycle is certain, kinematic velocity is higher, then the delayed macroscopic token that is synchronized with the movement is more obvious;
3. motion characteristics is poor, easy generation is impacted and vibrations, present most motion controller realizes displacement to individual kinematic axis, speed and Acceleration Control, the jerk characteristic (jerk) characterizing impact endurance test shock motion characteristics then seldom controls, this makes to impact when high-speed motion and shake obviously, on the other hand, delayed due to what move, motion controller needs execution interpolation operation after the one or more control cycle of execution, carry out correction motion deviation, the correction of each movement warp all needs to be realized by the size of change power or moment and direction, the change of this power or moment also makes the dynamic be synchronized with the movement be deteriorated.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of mechanical linear reciprocating synchronous device, this mechanical linear reciprocating synchronous device structure is simple, and synchronism is high, and power is large, and rigidity is strong, and reaction is fast, quiet operation.
The present invention in order to the technical scheme solving its technical matters and adopt is: a kind of mechanical linear reciprocating synchronous device, comprise load-transfer device, separate screw rod, manipulator and line slideway, separate screw rod can rotational positioning on load-transfer device one end, separate screw axial to place along load-transfer device sense of motion, manipulator can slide and be positioned on line slideway, line slideway is fixed on the side of load-transfer device Width, also be provided with motor, main drive shaft, first, two, three drivings device, cam mechanism, motor power exports to main drive shaft, first, two, three drivings device respectively by the power transmission of main drive shaft to the driven roller of load-transfer device, separate screw rod and cam gear, cam mechanism driving manipulator linearly slide, concrete structure is: cam mechanism comprises a swing link cam mechanism and a screw mandrel, 3rd power drive drives the cam of swing link cam mechanism to rotate, the fork axle of swing link cam mechanism drives screw mandrel to rotate, screw mandrel is threaded with manipulator, the cam of swing link cam mechanism is subject to the drive of the 3rd power drive and rotates, the fork of swing link cam mechanism makes positive and negative reciprocally swinging, and then just do batch (-type) rotating (fork axle generally adopts booster engine speedup to be connected with between screw mandrel) by the fork axle of swing link cam mechanism with screw mandrel, namely manipulator does the slip of batch (-type) reciprocating linear, this device power is exported by a motor, by first, two, three drivings device pass to the driven roller of load-transfer device respectively, separate the cam gear of screw rod and driving mechanical hand straight-line motion, a propulsion source just ensure that the synchronism of its three kinematic mechanisms driven by the structure that Purely mechanical exports respectively, ensure the conformability in whole device busy step, effectively prevent from interfering each other.
As a further improvement on the present invention, first, second and third driving device described is by Timing Belt and synchronous pulley composition, can certainly be the driving device formed by chain and sprocket wheel, can also be that the form of gear pair carrys out transmission, this class formation be all the equivalent replacement of this patent.
Advantageous Effects of the present invention is: the present invention adopts mechanical transmission mode, by the transmission respectively of a propulsion source, its power is large, rigidity is strong, synchronism is accurate, because its core adopts cam mechanism, the outline of cam is continuously smooth, and during cam high-speed motion, whole device also can keep muting function, avoid heavy duty, vibrations that high-speed motion brings, impact, ensure that each inter-agency synchronized movement precision, and be pure mechanical drive due to it, its reaction is fast, without the need to the response time of electronic controller, it effectively improves the production efficiency of manufacturing line.
