Abstract
The invention relates to a transmission mechanism of a machining planer. The transmission mechanism comprises a motor, a small belt pulley, a big belt pulley, a non-circular gear and a sliding block. The motor is connected with big and small belt transmission devices; the big and small belt transmission devices are connected with the non-circular gear; and a reciprocating sliding block link mechanism is hinged between a big and small gear transmission mechanism and a shaper slipway. The transmission mechanism is simple in structure, low in vibration, low in noise, stable in movement and high in return speed, provides a uniform cutting force or a planer cutter, is high in machining efficiency and high in quality, and has wide practicability.
Description
Technical field
The present invention relates to a kind of transmission mechanism, especially relate to a kind of machined planer transmission mechanism.
Background technology
At present, in the machined field, common planer transmission mechanism all is the plane six-bar linkage with quickreturn characteristics, by a sine mechanism and a crank guide rod mechanism series connection, and to be connected a parts with major axis by another non-round pinion between big or small belt drive unit and the non-circular gear drive device and be connected series connection, therefore working together, such planer mechanism can increase friction between parts and the parts, loss power, serious wear between the parts, can often change parts, and mechanical oscillation are large, the difficult control of noise.
Summary of the invention
The objective of the invention is to overcome weak point of the prior art, provide a kind of simple in structure, the cutter head cutting speed is even, stable performance, the machined planer transmission mechanism that service efficiency is good.
Technical scheme: for achieving the above object, a kind of machined planer transmission mechanism includes motor, small pulley, large belt wheel, non-circular gear and slide block.Described motor links to each other with big or small belt drive unit, and big or small belt drive unit is connected with described non-circular gear, is hinged with the sliding-block linkage that moves reciprocatingly between big or small gear drive and the shaping machine slideway.
Described non-circular gear drive device is made of non-circular gear, the connecting rod that is fixed on non-circular gear axle, connecting pin and the opposite side of non-circular gear one side.
Be connected by the non-circular gear axle between described big or small belt drive unit and the non-circular gear drive device.
Described non-circular gear axle is fixed on arranged off-centre on the non-circular gear.
Beneficial effect: compared with prior art simple in structure, conservation of power is vibrated littlely, and noise is little, motion steadily, opening speed strengthens, and provides bite even for the planer cutter, working (machining) efficiency is high and quality good, has widely practicality.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the movement velocity change curve of cutter head within a period of motion of prior art.
Fig. 3 is the movement velocity change curve of cutter head of the present invention within a period of motion.
Among Fig. 1: 1, motor; 2, small pulley; 3, belt; 4, non-circular gear; 5, non-circular gear axle; 6, large belt wheel; 7, connecting pin; 8, connecting rod; 9, slide block connecting pin; 10, slide block; 11, slideway.
The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
Shown in Figure 1, small pulley 2 is fixed on the turning cylinder of motor 1, and small pulley 2 is connected on the large belt wheel 6 by belt 3; Non-circular gear 4 and gear wheel 6 all are fixed on the non-circular gear axle 5, non-circular gear 4 off-centre are fixed on the non-circular gear axle 5, segment distance at the axis of rotation that departs from non-circular gear 4 is hinged with connecting rod 8, connecting rod 8 is hinged by connecting pin 7 and non-circular gear 4, connecting rod 8 other ends are hinged by slide block connecting pin 9 and slide block 10, and non-circular gear 4, connecting rod 8 and slide block 10 consist of a slider-crank mechanism.Motor 1 drives small pulley 2 rotations, transmits torque on the gear wheel 6 by belt 3, and gear wheel 6 is fixed together with non-circular gear 4, and moment is passed to non-circular gear 4 by non-circular gear axle 5; Non-circular gear 4 is hinged with connecting rod 8 again, and when non-circular gear 4 rotated, connecting rod 8 band movable sliders 10 moved reciprocatingly.
Shown in Figure 3, in the coordinate system of t-v, abscissa t is the planing cutter head run duration, and ordinate v is the planing cutter head movement velocity, and T represents the period of motion of planing cutter head.In impulse stroke planing cutter head movement velocity steadily (comparing with Fig. 2) in the period of motion, movement velocity is lower, and cutting force is large, and speed is fast during backhaul, high efficiency.The planing tool kinetic characteristic is at the uniform velocity large bite in the work, and planing tool quick return in the backhaul meets the Cutting Process requirement.
At work, large belt wheel drives non-circular gear 4 motions, again because the pitch curve of non-circular gear 4 is non-circle, so the gearratio i of two-wheeled is also uncertain: because non-circular gear 4, connecting rod 8 and slide block 10 have consisted of a slider-crank mechanism, lay just unique deciding of the position of connecting pin 7 and movement velocity that connecting rod 8 length are determined rear slider 10 on non-circular gear 4, the characteristics of motion that changes non-circular gear 4 can realize that slide block 10 kinetic characteristics satisfy Expected Results.The kinetic characteristic of non-circular gear 4 is determined by the gearratio i of predefined company two gear.As long as change the pitch curve of two-wheeled, the gearratio i that namely changes two gears can realize the characteristics of motion of the slide block 10 of expecting.
The above is embodiments of the invention, therefore all equivalences of doing according to the described structure of the present patent application scope, feature and principle change or modify, is included in the patent claim of the present invention.
