Technical field

Knife system is allowed the present invention relates to a kind of flexibility for gear shapping machine, belongs to field of machining.

Background technique

In recent years, with the rise of intelligent unmanned factory, higher reliability requirement is proposed to lathe.Gear shaping The stability of a processing unit of the machine as process final on Gear Production line, processing gear size directly determines entirely The processing efficiency of production line, and gear shapping machine allow knife system be influence the critical factor of gear size.Gear shaping machines at present The stability of part size out is poor, and the requirement of production line producer is not achieved.

As shown in Figure 1, common gear shapping machine is when processing gear workpieces 4, cam 1 is by power source drive, cam 1 and idler wheel 2 Connection, idler wheel 2 are connect by sleeve with resilient resistance members 5, and cutter 3 is mounted on cutter shaft 6, and cutter shaft 6 is located in sleeve, cutter 3 It is mounted on the bottom of cutter shaft 6, cutting of the cutter 3 to gear workpieces 4 is realized by the pumping in sleeve of cutter shaft 6. But during 3 backhaul of cutter after the completion of each stock removal action, cutter 3 is contacted with workpiece 4 and is scratched machined in order to prevent Face need to first pass through cam 1 and drive idler wheel 2, make idler wheel 2 by sleeve to Zola, so that so that cutter shaft 6 is moved to the left realization allows knife, bullet Property resistance piece 5 ensure that cam 1 and idler wheel 2 effectively contact.Cam 1 and 2 long-time of idler wheel under the effect of resilient resistance members 5, by Thermal expansion deformation, deformation force band movable arbor 6 move right, generate cutter 3 to gear workpieces 4 and cut more, cause gear workpieces 4 Size is unstable.

Summary of the invention

Present invention aim to address the unstable technical problems of the size of the gear workpieces of current gear shaping machining.

To realize above goal of the invention, the present invention provides a kind of flexibility for gear shapping machine and allows knife system, cam, idler wheel and First resilient resistance members, further include the second resilient resistance members and front end block, and the cam is mounted on second elastic resistance On part；First resilient resistance members are located at the ipsilateral of cutter shaft with gear workpieces to be processed, and second resilient resistance members are located at The other side opposite with the first resilient resistance members of cutter shaft；One end of first resilient resistance members is fixed on the rack, another End is by mobilizable sleeve connection to the idler wheel, and front end block side is fixedly connected in the rack, the other side The neighbouring sleeve and certain distance with interval.

Further, the resistance coefficient of second resilient resistance members is greater than the resistance system of first resilient resistance members Number.

Compared with prior art, the beneficial effects of the present invention are:

The present invention will allow the driving portion cam of knife system to be connected to elasticity using elasticity displacement principle by a set of spring mechanism Second big resilient resistance members one end of coefficient allows enforcement division idler wheel, sleeve and the cutter shaft of knife system to be connected to coefficient of elasticity small by the One end of one resilient resistance members, and front end block is set in coefficient of elasticity small one end, when driving portion and enforcement division by heat because being become When shape causes error, due to front end block be it is fixed, and the second resilient resistance members be it is elastic, deflection can be to second Resilient resistance members direction is mobile, i.e., error is mobile to the big one end of coefficient of elasticity, and the position of cutter shaft will not change, and cuts ruler It is very little also to change, to ensure that the stability of tool position, realize the reliable and stable knife that allows.

Detailed description of the invention

Fig. 1 is a kind of existing structural schematic diagram for allowing knife system；

Fig. 2 is the structural schematic diagram of one embodiment of the invention.

Specific embodiment

Preferred descriptions are made to the present invention in the following with reference to the drawings and specific embodiments.

As shown in Fig. 2, the present invention allows one embodiment of knife system for the flexibility of gear shapping machine, including cam 1, idler wheel 2, First resilient resistance members 5, the second resilient resistance members 7 and front end block 8, the cam 1 are mounted on second resilient resistance members 7 On；First resilient resistance members 5 are located at the ipsilateral of cutter shaft 6, second resilient resistance members 7 with gear workpieces 4 to be processed In the other side opposite with the first resilient resistance members 5 of cutter shaft 6；One end of first resilient resistance members 5 is fixed on the rack, By mobilizable sleeve connection to the idler wheel 2,8 side of front end block is fixedly connected in the rack other end, The other side is adjacent to the sleeve and certain distance with interval.Sleeve is movable, it can swings, the amount of swinging is exactly Relieving amount, front end block 8 can limit the compression travel of the first resilient resistance members 5, to limit cutter shaft 6 to 4 side of gear workpieces To mobile distance.When driving portion cam 1 and enforcement division idler wheel 2, sleeve and cutter shaft 6 cause error because of temperature distortion, due to Front end block 8 be it is fixed, and the second resilient resistance members 7 be it is elastic, deflection can be to 7 direction of the second resilient resistance members Mobile, i.e., error is mobile to the big one end of coefficient of elasticity, and the position of cutter shaft 6 will not change, and cutting size would not also become Change, to ensure that the stability of 3 position of cutter, realizes the reliable and stable knife that allows.The distance between front end block 8 and sleeve basis Actual needs is adjusted, and guarantees that when cutter shaft 6 moves down be vertical direction when adjustment, while sleeve is contacted with front end block 8 But it does not stress.Sleeve is swing component, and when the perfect condition of adjustment is that cutter shaft 6 moves downward, sleeve contacts but not with front end block 8 Stress, i.e. 0 distance state, when 6 backhaul of cutter shaft, journey drops in cam 1, at this moment will form gap between sleeve and front end block 8.

In one embodiment of the invention, the resistance coefficient of second resilient resistance members 7 is greater than first elasticity The resistance coefficient of resistance piece 5.Second resilient resistance members 7 necessarily have enough rigidity, and resistance coefficient is greater than the first elasticity Resistance piece 5, otherwise during cutter shaft 6 moves downward, cam 1 is possible to mobile to the second resilient resistance members 7, will lead to sleeve Swing to the left, sleeve touches front end block 8 not yet, that mean that during 6 down-cutting of cutter shaft be not it is vertical, just It is equivalent to cutter 3 not yet to cut gear workpieces 4 in place, this does not allow.

Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
