Compared to the prior art the utlity model has following characteristics and beneficial effect:
1, the utility model adopts servomotor to adjust the position of left and right side tool, and degree of regulation is higher, and error is little, avoids workman's manual adjustment and causes error.Left adjusting screw(rod) and right adjusting screw(rod) are guaranteed left side cutter and the equidistant relative displacement simultaneously of right side cutter, guarantee the symmetry of left and right side tool.
2, the direct regulation and control system of workman just can be controlled the advance and retreat of left and right sides cutter, guarantees the safety of workman when operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is servomotor place structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1, a kind of banner adjusting device of three-knife trimming, comprise main shaft 1, be set in the left side tool rest 2 of main shaft 1 left end and be set in the right side tool rest 3 of main shaft 1 right-hand member, described main shaft 1 surface is prolonged and is radially had feather key 4, and left side tool rest 2 is all connected with feather key 4 slippages with right side tool rest 3.
As shown in Figure 2, described main shaft 1 middle is provided with supporting seat 5, and supporting seat 5 tops are provided with output shaft servomotor 6 down, on servomotor 6 output shafts, are connected with drive bevel gear 7; Also include left adjusting screw(rod) 8, right adjusting screw(rod) 9, driven wheel of differential 10 and connecting rod 11, connecting rod 11 is rotationally connected with supporting seat 5, left adjusting screw(rod) 8 right-hand members are fixedly connected with right-hand member with the left end of connecting rod 11 respectively with right adjusting screw(rod) 9 left ends, driven wheel of differential 10 is set on connecting rod 11, and be fixedly connected with described driven wheel of differential 11 and drive bevel gear 7 engagements with connecting rod 11.
Described left adjusting screw(rod) 8 is provided with buttress screw thread, on the tool rest 2 of left side and the position of left adjusting screw(rod) 8 cooperations is provided with the copper nut 12 of setting one's teeth on edge, described set one's teeth on edge copper nut 12 and left adjusting screw(rod) 8 are threaded, described right adjusting screw(rod) 9 is provided with positive pitch thread, on right side the tool rest 3 and position of right adjusting screw(rod) 9 cooperations is provided with positive tooth copper nut 13, and described positive tooth copper nut 13 and right adjusting screw(rod) 9 are threaded.
