The transmission mechanism of the shaper has simple structure, small vibration, low noise, stable running and large return speed, provides uniform cutting force for planer cutters, is high in processing efficiency and good in quality, and has wide practicability.
Description
Technical field
The utility model relates to a kind of transmission mechanism, especially a kind of transmission mechanism that is applicable to shaping machine.
Background technology
At present, common shaping machine transmission mechanism all is the plane six-bar linkage with quickreturn characteristics in the machined field, by a sine mechanism and a crank guide rod mechanism series connection, each bar of appropriate design is grown and installation site as requested again, can realize follower lever almost constant speed's motion in impulse stroke, and when idle running, return fast, the driven member of this mechanism is the big (see figure 2) of the movement velocity curvilinear motion amplitude of planing cutter head, this planing cutter head is inhomogeneous at the impulse stroke medium velocity, and cutting force is also inhomogeneous.The cutter head kinetic characteristic curve of this at present used class mechanical type shaping machine all can not change, the cutting speed of cutter head changes inhomogeneous, so the cutting ability instability of such planer, tool damage is serious, opening speed changes fluctuation greatly, the difficult control of mechanical oscillation and noise.
Summary of the invention
The purpose of this utility model is to overcome weak point of the prior art, provides a kind of simple in structure, and the cutter head cutting speed is even, stable performance, the shaping machine transmission mechanism that service efficiency is good.
Technical scheme: for achieving the above object, planer transmission mechanism of the present utility model, comprise motor, the big or small belt drive unit that links to each other with motor, the size belt drive unit is connected with the non-circular gear transmission mechanism, is hinged with the sliding-block linkage that moves reciprocatingly between big or small gear drive and the shaping machine slideway.
Described big or small belt drive unit is made of the big belt wheel that is fixed on small pulley on the motor, connect through belt; Described non-circular gear transmission mechanism by be fixed on non-round gear wheel on the non-round Large Gear Shaft During, be meshed and be fixed on non-round gear wheel and the same axle of big belt wheel on non-round pinion constitute; Described be fixed on the same axle of big belt wheel on non-round pinion arranged off-centre; The described non-round gear wheel arranged off-centre that is fixed on the non-round Large Gear Shaft During; Described sliding-block linkage is made of the connecting rod that the slide block, the two ends that are located in the slideway are articulated in respectively on slide block and the non-round gear wheel.
Beneficial effect: compared with prior art simple in structure, vibrate for a short time, noise is little, motion is steady, and opening speed strengthens, and the cutting force of providing for the planer cutter is even, and cutting ability is stable, mechanical oscillation and noise are little, and working (machining) efficiency height and quality are good, have widely to use.

Fig. 1 is a structural representation view of the present utility model.
Fig. 2 is the movement velocity change curve of cutter head in a period of motion of prior art.
Fig. 3 is cutter head of the present utility model movement velocity change curve in a period of motion.
Fig. 1: 1-motor, 2-small pulley, 3-belt, the non-round gear wheel of 4-, the non-round Large Gear Shaft During of 5-, the big belt wheel of 6-, 7-axle, the non-round pinion of 8-, 9-connecting pin, 10-connecting rod, 11-slide block connecting pin, 12-slide block, 13-slideway.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
Shown in Figure 1, small pulley 2 is fixed on the power transmission shaft of motor 1, and small pulley 2 is connected on the big belt wheel 6 by belt 3; Non-round pinion 8 and big belt wheel 6 all are fixed on the axle 7, non-round pinion 8 and non-round gear wheel 4 engagements, and two gear centres are apart from remaining unchanged; Non-round gear wheel 4 off-centre are fixed on the non-round Large Gear Shaft During 5, on a segment distance of the axis of rotation that departs from non-round gear wheel 4, be hinged with connecting rod 10, connecting rod 10 is hinged by connecting pin 9 and non-round gear wheel 4, connecting rod 10 other ends are hinged by slide block connecting pin 11 and slide block 12, and non-round gear wheel 4, connecting rod 10 and slide block 12 constitute a slider-crank mechanism.Motor 1 drives small pulley 2 rotations, transmits torque on the big belt wheel 6 by belt 3, and big belt wheel 6 is fixed together with non-round pinion 8, and moment is passed to non-round pinion 8 by axle 7; Non-round pinion 8 and non-round gear wheel 4 engagements, non-round gear wheel 4 is hinged with connecting rod 10 again, and when non-round gear wheel 4 rotated, connecting rod 10 drove slide block 12 and moves 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 first period of motion of planing tool.In impulse stroke planing cutter head movement velocity steadily (comparing with Fig. 2) in the period of motion, its speed of service is lower, and cutting force is big, and speed is fast during backhaul, high efficiency.The planing tool kinetic characteristic is at the uniform velocity big cutting force in the work, and planing tool quick return in the backhaul meets the Cutting Process requirement.
At work, non-round pinion 8 drives non-round gear wheel 4 motions, and again because the pitch curve of two gears is non-circle, the gearratio i of two gears is also uncertain; Because non-round gear wheel 4, connecting rod 10 and slide block 12 have constituted a slider-crank mechanism, lay the position of connecting pin 9 and just unique the deciding of movement velocity that connecting rod 10 length are determined rear slider 12 on non-round gear wheel 4, the characteristics of motion that changes non-round gear wheel 4 can realize that slide block 12 kinetic characteristics satisfy Expected Results.The kinetic characteristic of non-round gear wheel 4 is determined by the gearratio i of predefined two gears.As long as change the pitch curve of two gears, the gearratio i that promptly changes two gears can realize the characteristics of motion of the slide block 12 of expecting.
