Specific embodiment
The present invention is described in detail With reference to embodiment.
Present system is as depicted in figs. 1 and 2, and decelerating motor 1 connects ball-screw 2, and ball-screw 2 can also use roller silk
Thick stick drives high precision ball lead screw 2 to rotate using the decelerating motor 1 of high reduction ratio, and the feed screw nut 3 on ball-screw 2 passes through
Feather key 4 and adjusting set 5 connect thrust bearing 6, and thrust bearing 6 connects the first drum shaft 7, the second rolling of the first drum shaft 7 connection
Cylinder axis 8, the first drum shaft 7 can be along its axial displacement, 8 axial restraint of second tin roller axis, second tin roller axis 8 and the first drum shaft
The 7 chief and vice bevel gear sets 9 of connection, second tin roller axis 8 and the first drum shaft 7 are passed by the chief and vice bevel gear set 9 for eliminating backlash
Dynamic, when the axial movement of the first drum shaft 7, second tin roller axis 8 and the first drum shaft 7 can generate relative rotation, be separately mounted to
The first cutting edge 11, the second cutting edge 12 on first drum shaft 7 and second tin roller axis 8 generate side clearance.Since gear set is continuously
Gap engagement, gear helical angle determine that the influence of no elastic deformation in the process, therefore, installation is high-precision in the shaft end of the first drum shaft 7
Linear displacement transducer 10 is spent, measures the axial displacement of the first drum shaft 7 directly to converse accuracy roller and cut between side
Gap.
When system works, the adjustment of cutting edge side clearance is adjusted to 0 interstitial site in assembling factory, sets linear displacement transducer
10 initial zero position is arranged between the first cutting edge 11, the second cutting edge 12 automatically according to the thickness of supplied materials to be sheared and physical characteristic
Gap and the shift value for being scaled the first drum shaft 7, decelerating motor 1 drive ball-screw 2 to rotate, and drive feed screw nut 3, feather key
4, adjusting set 5, thrust bearing 6 and the axial movement of the first drum shaft 7, the linear displacement transducer positioned at 7 shaft end of the first drum shaft
10 the first drum shaft of real-time detection, 7 axial displacement simultaneously feeds back to servo-system, realizes the position of the first drum shaft 7 axial movement
Control.
Present system advantage also resides in:
1. the rotary encoder of abandoning tradition detects the angular displacement of drum shaft and uses high-precision straight-line displacement
Sensor directly detects axial displacement, eliminates the influence of rigging error and regulating mechanism idle stroke.
2. using servo-system, realize that roller is cut side clearance and adjusted by position control mode.
3. using high ratio speed-down servo motor, large torque in adjustment process, the speed of low inertia are realized
Control.
The above is only not to make limit in any form to the present invention to better embodiment of the invention
System, any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
