There is cam, the cam to be engaged always with idler wheel, the idler wheel be mounted on elastic damping part on, the elastic damping part with
The installation main shaft of cutter matches.
For gear shapping machine by knife system, it includes motor, and the motor drives slider-crank mechanism by the first synchronous belt, described
Slider-crank mechanism is connected with cutter, and cutter is driven to move up and down, and cuts workpiece；Pacify on the slider-crank mechanism
Equipped with cam, and cam is rotated synchronously with slider-crank mechanism, the cam is remained with idler wheel to be contacted, the idler wheel
Mounted on one end of lever, the lever is in contact with idler wheel always by elastic damping part, and the other end of the lever passes through
Connecting rod is matched with the installation main shaft of cutter.
The utility model has the advantages that：
1, it allows knife system by using the first, cutter can be made to pass through idler wheel by elastic damping part and connect always with cam
Touch, and then ensure that cutter allows knife curve by knife by what cam designed, i.e., after the completion of Tool in Cutting, cutter far from workpiece backhaul,
Cutter is avoided to scratch machined workpiece, realization allows knife.
It 2, can be by being mounted directly cam on slider-crank mechanism and driving by using second of lever by knife system
It moves its and realizes and rotate synchronously, elastic damping part makes one end of lever pass through idler wheel always with cam contact, and the other end of lever is logical
It crosses connecting rod to be attached with cutter, realizes that cutter allows knife curve allow knife by designed on cam.
3, it is used as the knife system that individually allows using lever mechanism, effectively avoids in the first, elastic damping part is direct
It is contacted with the main shaft of cutter, and generates the defect of frictional heat, improve its stability, effectively avoid expanded by heating change
Shape improves dimensional accuracy.
4, play the role of labour-saving by using lever principle, the rigidity of elastic damping part can be reduced, reduce system
Calorific value.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is that the first of the utility model allows knife system structure diagram.
Fig. 2 is that the utility model is torn open and allows knife system structure diagram for second.
In figure：Motor 1, the first synchronous belt 2, the second synchronous belt 3, axis 4, cam 5, idler wheel 6, slider-crank mechanism 7, elasticity
Damping piece 8, cutter 9, workpiece 10, lever 11, connecting rod 12.
Fabrication cycles process：A- feeds, B- cuttings, C- allow knife, D- backhauls.
Specific implementation mode
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
Embodiment 1：
As shown in Figure 1, gear shapping machine is by knife system, it includes motor 1, and the motor 1 drives crank by the first synchronous belt 2
Slide block mechanism 7, the slider-crank mechanism 7 are connected with cutter 9, and cutter 9 is driven to move up and down, and cut workpiece；The
Two synchronous belts 3 drive the belt wheel being mounted on axis 4, the other end of the axis 4 to be equipped with cam 5, and the cam 5 begins with idler wheel 6
It is engaged eventually, the idler wheel 6 is mounted on elastic damping part 8, and the elastic damping part 8 and the installation main shaft of cutter 9 match
It closes.
Knife system is allowed by using above-mentioned, in the course of work, is moved up and down with cutter 9 by slider-crank mechanism 7,
Workpiece 10 is cut, for the second synchronous belt 3 by axis 4 with 5 synchronous rotary of moving cam, elastic damping part 8 makes cutter 9 pass through rolling
