Problems solved by technology

The disadvantage is: the effective travel of the cross guide rail is limited, unlike the linear guide rail, which can leave a relatively large travel range
[0004] The characteristics of the M / V linear guide rail: it can realize high-precision and smooth linear motion, and the load it can bear is much higher than that of the linear guide rail. Leave a relatively large travel range

Embodiment Construction

[0023] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0024] figure 1 The shown pair of roller guide rails includes a T-shaped guide rail 1 and a slider 2. The T-shaped guide rail is composed of an upper rectangular bar 3 and a lower rectangular bar 4. The lower rectangular bar is installed on the bottom of the upper rectangular bar. In the middle position, the upper rectangular bar is provided with four equal bevels 5 in the length direction, and the bevels can be at least forty-five degrees, and the upper two bevels and the lower two bevels The angles are arranged symmetrically, and the left two oblique angles are arranged symmetrically with the right two oblique angles. The upper rectangular bar is provided with at ...

Abstract

The invention relates to the technical field of guide rails, in particular to a roller guide rail pair. The roller guide rail pair comprises a T-shaped guide rail and sliding blocks, the T-shaped guide rail is composed of an upper rectangular strip and a lower rectangular strip, the lower rectangular strip is installed in the middle position of the bottom of the upper rectangular strip, the upperrectangular strip is provided with four equal oblique angles in the length direction, the oblique angles can be at least 45 degrees, the upper two oblique angles and the lower two oblique angles are symmetrically arranged, and the left two oblique angles and the right two oblique angles are symmetrically arranged; and at least two guide rail mounting holes which are provided with counterbores andpenetrate through the lower rectangular strip are formed in the upper rectangular strip, and at least one sliding block is arranged on the T-shaped guide rail. The roller guide rail pair has the characteristics that the tightness of the guide rail can be adjusted according to the size of a load on an installation site, and the roller guide rail pair is convenient to install, debug, maintain and replace and easy to produce.

Description

technical field [0001] The invention relates to the technical field of guide rails, in particular to a roller guide rail pair. Background technique [0002] Existing linear guides, especially ordinary and high-grade linear guides, before installation, some are loose, some are tight, some are tight before installation, and they are already loose after installation. Pushing, you can hear the sound of the ball. The slider installed on the machine cannot be debugged on site, and can only be returned to the factory for debugging. This is troublesome. The sliders of the existing linear guide rails have been adjusted before leaving the factory. , it cannot be adjusted during use, and can only be returned to the manufacturer for tightness adjustment, which is troublesome, so most users use the method of replacing the slider to ensure normal operation. If the gap is too small, the friction of the guide rail will increase. If the clearance is too large, the guiding precision of the g...
