Abstract
A non-circular gear quick-return device for main movement of a gear shaper comprises a slider, wherein a first non-circular gear and a second non-circular gear of the quick-return device are engaged mutually; one end of a first connecting rod is fixed with the second non-circular gear; and one end of the second connecting rod is connected with the first connecting rod while the other end is connected with the slider. The non-circular gear quick-return device for main movement of a gear shaper of the utility model, through adopting the operation manner of mutual engagement of non-circular gears, driving the connecting rod to move via the movement of the non-circular gear, and then driving the slider via the connecting rod, enables a cutter of the gear shaper to gain an uniform velocity and an excellent quick-return characteristic within the main movement operating stroke, reduce operating idle stroke, and increase return speed and cutting operation efficiency.
Description
Technical field
The utility model relates to a kind of gear shapping machine that is used for, and adopts the non-circular gear structure, the device of control gear shapping machine cutter fast moving.
Background technology
In the transmission mechanism, if the revolution of motor constant speed, the impulse stroke of driven member is slow, and opening speed is fast, claims quickreturn characteristics.Traditional gear shapping machine main motion mechanism adopts usually the slider-crank mechanism of the heart is realized reciprocal gear shaping motion.When crank was the constant rotational speed driving, the motion of slide block was that non-symmetry at the uniform velocity moves back and forth.Reciprocal gear shaping forms of motion like this, on the one hand, owing to do not have anxious characteristic of returning, return interval is identical with the gear shaping impulse stroke time, is unfavorable for improving working (machining) efficiency; On the other hand, because gear shaping stroke medium velocity changes greatly, cutting speed is inconsistent in the gear shaping process, produces bigger cutting and impacts, and influences the uniformity and the tooth accuracy of the flank of tooth.
Gear shapping machine just develops towards direction at a high speed, and when gear shaping speed improved, quickreturn characteristics and gear shaping stroke uniform speed seemed even more important.Therefore, obtaining the quickreturn characteristics of gear shaping reciprocating stroke, make gear shaping stroke cutting speed constant as far as possible, is the important content of the research and development of high speed gear shaper.
Summary of the invention
The technical problems to be solved in the utility model is to overcome existing gear shapping machine main motion not have quickreturn characteristics, the big defective of processing stroke motion velocity variations, and a kind of non-circular gear mechanism device of optimizing kinetic characteristic that has that applies to the gear shapping machine main motion is provided.
The purpose of this utility model is achieved in that a kind of anxious return device of non-circular gear that applies to the gear shapping machine main motion, comprise slide block, the first non-round gear teeth of anxious return device match with second non-circular gear, first connecting rod one end is fixedly mounted on second non-circular gear, second connecting rod one end is connected with first connecting rod, and the other end is connected with slide block.
The anxious return device of the non-circular gear that applies to the gear shapping machine main motion that the utility model provides, by adopting non-circular gear to match, and by the action of the motion drivening rod of non-circular gear, drive the method for operation of slide block work again by connecting rod, make the gear shapping machine cutter obtain speed uniform properties and good quickreturn characteristics in the main motion impulse stroke, shortening work idle stroke improves opening speed, improves the efficient of cutwork.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 adopts the utility model rear slider rate curve.
The specific embodiment
The utility model is applied to the main motion of gear shapping machine, and its structure is as follows: the anxious return device of non-circular gear
A kind of anxious return device of non-circular gear that applies to the gear shapping machine main motion, comprise slide block 5, the first non-round gear teeth 1 of anxious return device match with second non-circular gear 2, first connecting rod 3 one ends are fixedly mounted on second non-circular gear 2, second connecting rod 4 one ends are connected with first connecting rod 3, and the other end is connected with slide block 5.
During the utility model work, first non-circular gear 1 drives 2 motions of second non-circular gear, because first connecting rod 3 one ends are fixedly mounted on second non-circular gear 2, the first connecting rod 3 and second non-circular gear 2 do not produce relative motion, the motion of second non-circular gear 2 drives first connecting rod 3 and does the on-circular operation, drive second connecting rod 4 actions by first connecting rod 3, second connecting rod 4 drives slide block 5 and does rectilinear motion, has finally formed the reciprocal gear shaping motion of gear shapping machine.
Adopt this device slide block rate curve as shown in Figure 2, time that the backhaul process is consumed in the whole stroke and the ratio between the progress of work are 0.53, have improved operating efficiency.At the then approximate straight line of impulse stroke section, velocity uniformity is improved, and finishes gear shaping to trend towards even velocity in the gear shaping process, and uniformity index is 0.084.Backhaul stage velocity variations is obvious, makes the service behaviour of gear shapping machine main motion obtain tangible improvement, and main shaft not only can be finished gear shaping work with stable speed, and has tangible quickreturn characteristics.
