Guide rails unloading gear for transverse slide carriage

Abstract

The invention discloses a guide rail unloading device for a transverse slide carriage, which belongs to the field of machine tools. The guide rail unloading device is provided with a slide carriage and is characterized in that the upper plane of the transverse slide carriage is provided with an inclined hole of 75 degrees, and a retaining nut is connected thereon through screw threads; an inclined guide rail of 15 degrees is machined on a transverse beam and is embedded with a steel strip; a bearing support is arranged in the inclined hole of the slide carriage to play a role in guiding; the lower end of the slide carriage is provided with a self-aligning roller bearing through a pin shaft, and the self-aligning roller bearing rolls on the steel strip of the transverse beam; and a belleville spring piece is arranged between the upper end of the slide carriage and the retaining nut. The guide rail unloading device greatly reduces the pressure on a standard guide rail of the transverse rail, and reduces the gib abrasion between the transverse beam and the transverse slide carriage so that the transverse beam stress is distributed evenly to reduce the deformation of the transverse beam, and the motion form is changed from sliding into rolling to reduce the dragging force of the transverse slide carriage and finally improve the precision of a machine tool.

Description

technical field [0001] The invention belongs to the field of machine tools, in particular to a guide rail unloading device for a machine tool transverse slide plate. Background technique [0002] As we all know, with the development of machining technology and the needs of the machining industry, large-scale gantry machine tools that can process large workpieces have emerged. In order to meet the processing needs of high-power and high-torque, the beam stepped rectangular guide rail has become the mainstream design of large-scale gantry machine tools. ,is widely used. In order to ensure the machining accuracy, the frame rigidity of the machine tool is greatly enhanced, and the dead weight of the horizontal slide plate and the ram milling head is significantly increased, resulting in a series of problems: [0003] 1. The self-weight of the transverse slide plate and the milling head of the ram are all loaded on the beam reference guide rail, which greatly increases the load ...

AI Technical Summary

Problems solved by technology

[0003] 1. The self-weight of the transverse slide plate and the milling head of the ram is all loaded on the beam reference guide rail, which greatly increases the load on the support surface of the beam reference guide rail, which is easy to cause deformation of the guide rail

[0004] 2. With the operation of the machine tool, when the support surface of the beam reference guide rail is under great pressure, the wear of the insert between the beam and the transverse slide plate is intensified, which seriously affects the accuracy of the machine tool

[0005] 3. The pressure between the support surface of the beam reference guide rail and the transverse slide plate increases, the friction force increases accordingly, and the torque required for the drive motor of the transverse slide plate increases, which causes additional load on the machine tool and affects the operation of the machine tool
