Nut 21, which matches to merge, provides guiding.
The working principle of the invention: when the thickness of supplied materials steel plate increases, hydraulic nut 17 pressurizes first, thus
Connection is tiltedly carved 20 entirety and raised up, on the one hand reduces resistance when lap adjustment, together by the depressing force for overcoming disc spring group 19
When avoid the friction between inclined-plane from causing to damage；Then motor 13 rotates in the forward direction under the accurate control of absolute value encoder 16
Certain angle drives the leading in guiding bottom plate 22 of the feed screw nut 21 with guide groove so that left and right screw synchronous be driven to rotate
Downwards, predetermined position is proceeded to；Finally, the pressure release again of hydraulic nut 17 after being adjusted in place, connection tiltedly carves 20 in disc spring
On the feed screw nut 21 for pressing against guide groove under the active force of group 19 again, to realize that connection is tiltedly carved 20 and moved upwards, reach
To crank mechanism brachium is reduced, compensation steel strip thickness increases the purpose that bring influences.When supplied materials steel plate thickness reduce when
It waits, then 13 direction of rotation of motor is on the contrary, remaining process is consistent, to reach increase crank mechanism brachium, compensation strip is thick
Degree increases the purpose that bring influences；It is synchronous finally to realize that upper and lower compression bonding apparatus achievees the purpose that when crimping steel plate.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of the technical program, should all be covered in the present invention
Scope of the claims in.
