Mechanism for regulating spindle circumference phase variation of roll forming machine

Abstract

The invention discloses a mechanism for regulating the spindle circumference phase variation of a roll forming machine, comprising a left worm gear speed reducer, a right worm gear speed reducer, a worm shaft, a left spindle and a right spindle, wherein the worm shaft is arranged between the left and right worm gear speed reducers; and the left and right spindles are respectively connected with the left and right worm gear speed reducers. The mechanism for regulating the spindle circumference phase variation of the roll forming machine is characterized in that the worm shaft is divided into a left worm shaft and a right worm shaft, and a phase variation regulating mechanism is arranged between the left and right worm shafts. In the invention, the worm shaft is divided into the left worm shaft and the right worm shaft, and the phase variation regulating mechanism is arranged between the left and right worm shafts, so that the linear circumference phase regulation accuracy can reach 2 microns through the regulation between left and right regulation gears respectively arranged on the left and right worm shafts and a middle gear arranged between the left and right regulation gears, which greatly improves the phase regulation accuracy and realizes the step and quantification of the phase regulation; meanwhile, the invention has the advantages of simple structure, convenient operation and strong reliability.

Description

technical field [0001] The invention relates to a rolling machine tool, including a thread rolling machine, a gear rolling machine, a spline rolling machine, a skew rolling machine, a cross wedge rolling machine and other machine tool equipment whose main shaft circumferential phase needs to be adjusted; especially relates to a rolling machine main shaft circumferential phase variation adjustment mechanism . Background technique [0002] At present, the mechanical transmission system of rolling machine tools mainly includes a worm gear reducer, a worm shaft and a main shaft. The worm shaft is arranged between the left and right worm gear reducers. It is connected with the worm gear shafts of the left and right worm gear reducers, a tooling fixture is provided between the left and right main shafts, a workpiece is mounted on the tooling fixtures, and a roll forming die is provided on the left and right main shafts, The left and right worm gear reducers drive the left and rig...

Problems solved by technology

Since there are generally only 100 divisions on the adjustment dial, the accuracy of the angle circle phase variation adjustment can only reach 3.6°. If you want to adjust it more finely, you can only adjust the grid, or grid, or grid, its adjustment amount can only be estimated, and cannot be precise and quantified, so the phase adjustment accuracy is very poor
