AI Technical Summary

Technical Problem

The existing technology requires replacing support seats of different thicknesses when processing long tubes of different diameters. It cannot ensure that the front end of the long tube, the trolley feeding shaft and the wheel mold clamping end are coaxial, and the front end of the long tube is prone to drooping, resulting in inaccurate processing.

Method used

An adaptive automatic support method is adopted. By adjusting the first and second roller groups on the seat, the spacing is adjusted using the long tube's own gravity, and the roller groups are driven close to each other through the rocker bar to clamp the long tube, ensuring that the front, rear and bottom sides of the long tube are all supported, achieving the goal of no external support.

Benefits of technology

It achieves stable clamping of long tubes of different specifications, avoids damage from external forces, ensures that the axis of the long tube end coincides with the axis of the roller group, and improves processing accuracy and stability of automated production.

Abstract

The present invention discloses an adaptive automatic supporting method and device for a long tube, comprising an adjusting seat, a first roller with a middle portion recessed inwardly, a second roller with a middle portion recessed inwardly, and a rocker arm, wherein the first roller and the second roller are arranged opposite to each other and are slidably mounted on the adjusting seat, the rocker arm is located between the first roller and the second roller, the rocker arm is connected to a transmission component of a supporting device, one end of the rocker arm is hinged to the adjusting seat, and the other end of the rocker arm is tilted upward, and the transmission component can drive the first roller group and the second roller group to move; the end portion of the long tube enters between the first roller and the second roller, and the rocker arm can drive the rocker arm to swing when pressing the rocker arm, and when the rocker arm swings, it can drive the first roller and the second roller to approach each other, thereby causing the long tube to move along the outer wall of the recess of the first roller and the second roller to the middle position of the rollers, so that the axis of the end portion of the long tube can gradually coincide with the middle position of the first roller and the axis position of the second roller.
