Equal line speed turning device for making large screen template

Abstract

The utility model relates to an equilinear speed turning processing device for processing large-screen templates, which belongs to the field of mechanical engineering. It mainly includes: DC speed regulating motor, turntable transmission mechanism, knife row y-direction indexing mechanism, knife row z-direction advance and retreat mechanism, the connection method is: the output of the motor is connected to the input of the turntable transmission mechanism, the base of the turntable transmission mechanism and the The foundation is consolidated, the large carriage in the y-direction indexing mechanism of the knife row is arranged on the beam, and the z-direction advance and retreat mechanism of the knife row is arranged on the large carriage. Adopting the machine tool with the structure of the present invention, the rotating speed of the machine tool turntable is controlled by the computer to drive the turntable to carry out stepless speed change, and the horizontal division Δy of the knife row is measured and displayed by the grating and communicated to the computer control system for controlling the rotating speed of the DC motor , so as to moderately control the rotating speed of the turntable, ensure the cutting amount of the turning tool is consistent, and avoid the occurrence of chatter and tool breakage.

Description

technical field [0001] The invention relates to a turning processing device, in particular to a turning processing device with constant linear velocity for processing large-screen templates, which belongs to the field of mechanical engineering. Background technique [0002] FRP large screens need to be engraved with concentric circular fine stripes of various specifications. To mass-produce the above-mentioned FRP large screens, aluminum alloy templates must be processed first. Since the template has a variety of specifications, the largest specification is length by width: 3200mm×2400mm; the stripe spacing Δy is 0.35~0.5mm; the stripe depth t is 0.15~0.25mm; the processing of the whole template stripe needs to be indexed 9000~6000 times; Starting from the center of the turntable, when the turning tool is indexed in the radial direction, the speed of the turntable must be continuously variable (slowed down), so that the linear speed when turning different circles of stripes ...

Problems solved by technology

Its disadvantage is that the X-direction indexing movement of the spindle head cannot control the infinitely variable movement of the table according to a certain relationship. On the other hand, it cannot achieve thousands of times of precision indexing with an amount of 0.5mm and an error of 0.004.
