Shaft type part surface rolling and pressing reinforcing device based on piezoelectric type force sensors

Abstract

The invention relates to a shaft type part surface rolling and pressing reinforcing device based on piezoelectric type force sensors. The shaft type part surface rolling and pressing reinforcing device based on the piezoelectric type force sensors comprises a base, inclined block lifting mechanisms, telescopic mechanisms, guiding mechanisms, rolling and pressing head mechanisms and the piezoelectric type force sensors; the base is installed on a large supporting plate of a turning lathe; the two sides on the base are each provided with the corresponding inclined block lifting mechanism; each inclined block lifting mechanism is provided with the corresponding telescopic mechanism; each telescopic mechanism is provided with the corresponding guiding mechanism and the corresponding rolling and pressing head mechanism; each rolling and pressing head mechanism is provided with the corresponding piezoelectric type force sensor; and the rolling and pressing head mechanisms on the two sides are oppositely arranged. According to the device, micro adjustment of the rolling and pressing head mechanisms in the z axis direction of a machine tool is achieved through the inclined block lifting mechanisms; the rolling and pressing head mechanisms are made to always act on the surface of a workpiece through the telescopic mechanisms; when rolling and pressing machine is performed through the guiding mechanisms, rolling and pressing heads perform normal rolling and pressing machining on the surface of the workpiece; and the piezoelectric type force sensors are used for achieving real-time feedback and control on the rolling and pressing force.

Description

technical field [0001] The invention relates to a surface rolling strengthening device for shaft parts based on a piezoelectric force sensor, and belongs to the technical field of rolling processing. Background technique [0002] At present, in the rolling device in the field of rolling processing, the rolling head part is fixed relative to the rolling device. After a long time of rolling processing, the rolling device is prone to deformation due to stiffness problems, which in turn affects the rolling processing accuracy. In addition, most of the rolling devices use motor-driven actuators or hydraulic pumps to drive hydraulic cylinders to directly roll the workpiece through the rolling head. There is no rolling force detection device, and it is an open-loop control system. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides a surface rolling strengthening device for shaft parts based on piezoelectric force senso...
