A device and method for stepless adjustment of the angle of the main drive shaft of a three-rolling wire mill

Abstract

The invention discloses a stepless adjusting device and method for the tri-roller milling machine main transmission shaft angle. The device comprises a hand wheel, a worm, a worm wheel, a support core and a support. The worm wheel is connected with the support core which is fixed on the support. The worm is fixed on the support through a bearing and a bearing gland. The bearing is assembled on the worm wheel, and the hand wheel is mounted on the worm. When the product diameter and screw pitch change and needed to be adjusted, the bolts are loosened, and the hand wheel is rotated, the worm is driven to rotate, the support core is driven by the worm wheel to rotate around the support center till the support core is adjusted to the required position, and the bolts are fixed, so that the angle between the main transmission shaft and the support is changed, and the stepless adjusting effect is provided. The device and the method have the advantages that the problem that different products cannot be produced due to angle positioning is solved fundamentally, and the support core can be adjusted to any ideal positions.

Description

technical field [0001] The invention relates to a device and method for stepless adjustment of the angle of a main transmission shaft of a three-roller thread mill. Background technique [0002] When designing the angles of the main drive shafts of the existing three-roller wire milling machine, the angular positions between the three shafts and the horizontal line are directly determined. However, with the continuous increase and change of products, the angles between the three shafts and the horizontal plane of the machine tool The angle of A has been determined and fixed, and cannot be rotated. The original angle of the main drive shaft cannot be used for the production of various products. Such as figure 1 and figure 2 as shown, figure 1 is the front view of the original bracket, figure 2 The top view of the original bracket, in figure 1 The three main drive shaft holes marked in , are relatively fixed relative to the bracket itself, and cannot be changed after pr...

AI Technical Summary

Problems solved by technology

[0002] When designing the angles of the main transmission shafts of the existing three-roller wire milling machine, the angular positions between the three shafts and the horizontal line are directly determined. However, with the continuous increase and change of products, the angles between the three shafts and the horizontal plane of the machine tool The angle of A has been determined and fixed, and cannot be rotated. The original angle of the main drive shaft can no longer be used for the production of various products.

like figure 1 and figure 2 as shown, figure 1 is the front view of the original bracket, figure 2 The top view of the original bracket, in figure 1 The three main drive shaft holes marked in , are relatively fixed relative to the bracket itself, and cannot be changed after processing. Therefore, after the product diameter and pitch change during the production process, there will be 1. The product quality is unqualified; 2. , slow down, etc.
