Description
Technical field
The present invention relates to cutting field more particularly to a kind of reciprocating cutter mechanisms.
Background technique
Cutting is a kind of process equipment of the cutting of reciprocating motion realization material by driving cut-off knife, the reciprocal fortune of cut-off knife
Dynamic track determines the quality of the effect of the cropped efficiency of material and cutting, therefore, the machine for driving cut-off knife to move reciprocatingly
Structure is just particularly important in cutting.For example, 105970590 A of Chinese patent literature CN discloses a kind of automatic cutting system
The Scissoring device of system, the cut-off knife extended including rack and up and down further includes X to motion bracket, Y-direction motion bracket and up and down motion
Mechanism, the X are mounted on the rack to motion bracket and can move along front and back, and the Y-direction motion bracket is mounted on X to fortune
It can move on dynamic bracket and in left-right direction, the up-down mechanism is mounted on Y-direction motion bracket, the up and down motion
It is equipped with the rotatable and solid knife bar that can move back and forth up and down in mechanism, the lower end of the upper end of the cut-off knife and solid knife bar is fixed to be connected
It connects.
The Scissoring device of above-mentioned this automatic cutting system in the prior art, there are following problems:
First, the 1-5 row of [0060] section in the specification of the prior art discloses the following contents: described second
Gear unit includes rotatable eccentric shaft, flexible connection piece and at least one set of guide bearing group, and the eccentric shaft is rotationally
Be arranged drive shaft in and with drive shaft eccentric setting, the flexible connection piece include upper section deformation driving section and lower end vertically pass
The upper end in dynamic portion, upper section deformation driving section is fixedly connected with the end of eccentric shaft by screw, and the lower section is vertically driven
The lower end in portion is fixedly connected with the upper end of solid knife bar by screw.
Meanwhile the 3-5 row of [0061] section in specification discloses the following contents: one end of the drive shaft opens up
There is a cavity, the first bearing seat being fixedly connected with drive shaft is equipped in the cavity, the eccentric shaft can be turned by first bearing
It is supported in first bearing seat dynamicly.
The shortcomings that being designed in this way is: 1, structure is complicated for second gear unit, the connection relationship between drive shaft
More complicated, not only dismounting is inconvenient, and fault point is more, and cost is also higher.
2, second gear unit in the prior art includes rotatable eccentric shaft, flexible connection piece and at least one
Group guide bearing group, the eccentric shaft can be rotatably set in drive shaft and with drive shaft eccentric setting, i.e., in eccentric simultaneously

Sound is also larger.
Second, [0061] section row second from the bottom in the specification of the prior art discloses the following contents: the drive
Moving axis is rotatably supported in second bearing seat by second bearing；Also, by Fig. 3 in the patent document Figure of description
It is found that being provided with two bearing chambers for being separated by preset space length in second bearing seat, there are two second bearings, is separately positioned on two
In bearing chamber, i.e. two second bearings are predetermined distance settings.
The shortcomings that being designed in this way is: 1, two second bearings for being separated by preset space length are concentric bearings, hardly possible processing, and
It typically independently sells, concentricity is difficult to ensure, and the error of concentricity directly affects the cooperation precision and use of workpiece
Situation；Therefore, such design is difficult to meet high-precision requirement.
2, such design, two second bearings are separated by scheduled spacing, increase the length of cantilever, arm length not only structure
It is not compact enough, it is difficult to so that equipment is integrally accomplished exquisiteness, and cantilever is longer, power of toppling is also bigger, and mechanism is easy to cause to shake
It is dynamic, or even topple over, influence whole stability.
3, two independent bearing chambers are set in second bearing seat, this causes the difficulty of processing of bearing block larger, is fabricated to
This is higher.
