Combined heavy sliding linear guide rail

Abstract

The invention discloses a combined heavy sliding linear guide rail which comprises a plurality of guide rail bodies, a guide block and a mounting bottom plate, wherein the guide rail bodies are fixedly connected with the mounting bottom plate by virtue of fastening screws, and guided objects perform linear motion along the surfaces of the guide rail bodies; each guide rail body comprises an upper end surface and two side surfaces; the side surfaces are provided with anti-turning inclined surfaces which incline inwards; the guide block comprises upper guide blocks and side guide blocks; the guide rail bodies are respectively provided with the upper guide blocks or the side guide blocks or the upper guide blocks and the side guide blocks; the upper guide blocks are arranged on the upper end surfaces of part of the guide rail bodies and are higher than the upper end surfaces of the guide rail bodies; the side guide blocks are arranged on the two side surfaces of part of the guide rail bodies and are higher than the side surfaces of the guide rail bodies. By virtue of adjustment of a functional module, combined guide rails with different functions can be formed so as to meet different needs. The combined heavy sliding linear guide rail is high in operability, high in precision, good in controllability, good in reliability and can meet requirements of any working condition.

Description

technical field [0001] The invention relates to a heavy-duty linear guide rail used in mechanical environment test equipment, in particular to a combined heavy-duty sliding linear guide rail for a horizontal strong impact machine, belonging to the technical field of mechanical environmental test equipment. Background technique [0002] Sliding linear guides generally cooperate with sliders to support and guide moving parts, and make reciprocating linear motions in a given direction. It is used in linear reciprocating motion occasions, has a higher rated load than linear bearings, and can bear a certain torque at the same time, and can achieve high-precision linear motion under high load conditions. [0003] Sliding linear guides are mainly used in mechanical structures with relatively high precision requirements. There is no intermediate medium between the moving element and the fixed element, but rolling steel balls are used, so that the linear guide can be used for high-sp...

AI Technical Summary

Problems solved by technology

Under such working conditions, any one of the existing heavy-duty sliding linear guide rails and ready-made steel rails alone cannot meet the performance index requirements of the horizontal strong impact machine, and cannot ensure the reliability of the impact machine

[0008] Therefore, there are still many deficiencies in actual use in the existing heavy-duty sliding linear guides, which need to be further improved.
