Intelligent tension-adjusting gear

Abstract

The invention discloses an intelligent tension regulating device which comprises a support saddle and an idler pulley. The invention is characterized in that: the device also comprises a tension detection wheel, a pressure sensor which serves as a mandrel of the tension detection wheel, a single chip, an actuating motor which is arranged on the support saddle, two parallel guide roles and a ball bearing screw pair; wherein, a ball screw is arranged on the support saddle and is parallel to the two guide roles; the actuating motor is connected with the ball screw by a timing belt pulley mechanism; a glide seat is fixedly connected with a screw and is arranged on the two guide roles in a sliding way. The idler pulley is connected with the glide seat; the single chip is respectively connected with the pressure sensor and the actuating motor. The device can effectively guarantee the accuracy of the tension regulating, realizes intelligent control and has easy operation.

Description

technical field [0001] The invention relates to a tension adjustment device, in particular to an intelligent tension adjustment device for a reciprocating wire electric spark cutting machine tool. Background technique [0002] Currently widely used reciprocating wire EDM machine tools, due to irregular changes in the tension of the reciprocating electrode wire, it is difficult to achieve an ideal range for the surface roughness and dimensional accuracy of the workpiece, and all manufacturers are also aware of the Up to this point, some devices have been designed to control the tension of the electrode wire, such as the more commonly used weight-type tension adjustment device, which uses the self-weight of the guide wheel installed on the bracket to press the electrode wire to achieve the purpose of adjusting the tension. It is a purely mechanical control, which is affected by the manufacturing and installation precision, so that the accuracy of tension adjustment cannot be g...

[0002] Currently widely used reciprocating wire EDM machine tools, due to irregular changes in the tension of the reciprocating electrode wire, it is difficult to achieve an ideal range for the surface roughness and dimensional accuracy of the workpiece, and all manufacturers are also aware of the Up to this point, some devices have been designed to control the tension of the electrode wire, such as the more commonly used weight-type tension adjustment device, which uses the self-weight of the guide wheel installed on the bracket to press the electrode wire to achieve the purpose of adjusting the tension. It is a purely mechanical control, affected by the manufacturing and installation accuracy, so that the accuracy of tension adjustment cannot be guaranteed, and in the process of adjustment, it is necessary to manually complete the processes of wire taking, wire loading and wire tightening, which is not easy to operate
