Spindle circumferential phase variation adjusting mechanism for roll forming machine

Abstract

The invention relates to a spindle circumferential phase variation adjusting mechanism for a roll forming machine, which comprises a left and a right worm and gear reducers, a worm shaft and left and right spindles, wherein the worm shaft is arranged between the left and right worm and gear reducers, and the left and right spindles are respectively connected with the left and right worm and gear reducers. The invention is characterized in that the worm shaft is divided into left and right worm shafts, the left worm shaft is provided with a left adjusting gear, the right worm shaft is provided with a right adjusting gear, and the left adjusting gear and the right adjusting gear are connected by a duplicate gear. By dividing the worm shaft into the left and right worm shafts, respectively arranging the left and right adjusting gears on the left and right worm shafts and connecting the left and right adjusting gears by the duplicate gear, the adjusting mechanism realizes the stepped and quantified adjustment on the phase and greatly improves the phase adjustment precision, and the linear circumferential phase adjustment precision can be up to 2 mu m. Besides, the adjusting mechanism has the advantages of simple structure, convenient operation and high 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 tools 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 right main sh...

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
