Problems solved by technology
However, since the combined heavy-duty linear guide rail is composed of multiple guide rail bodies, it needs to cooperate with multiple sets of sliders. If the guide rail and the slider are directly processed into integral parts, the processing errors caused by ordinary processing methods will cause the slider and the guide rail to fail. Unable to assemble smoothly
At this time, the processing accuracy needs to be greatly improved, and the processing cost will also increase significantly.

The invention discloses a method for improving reliability of a combined type heavy linear guide rail and a device for executing the method. The device comprises guide rail bodies, guide rail mounting plates, base plates and sliding blocks, wherein the guide rail bodies are fixedly mounted on the guide rail mounting plates, the guide rail mounting plates are fixedly connected with the base plates, the cross sections of the guide rail bodies are isosceles trapezoid-shaped; the guide rail mounting plates are arranged to adopt isosceles trapezoid-shaped cross sections; the guide rail bodies are matched with the isosceles trapezoids on the guide rail mounting plates through the isosceles trapezoid-shaped cross sections; the sliding blocks sleeve the guide rail bodies to realize sliding fit. According to the method and the device disclosed by the invention, the whole guide rail is changed to be the coordinated split guide rail, so that the reliability of the guide rail is improved, the machining accuracy requirement is reduced, the processing cost is reduced, and the problems that the conventional combined heavy linear guide rail is high in machining accuracy requirement, difficult to eliminate machining error and difficult to assemble can be solved; meanwhile, the combined type heavy linear guide rail prepared according to the invention is strong in universality, high in precision, good in controllability and reliability, low in machining difficulty and capable of meeting the requirements on 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 method and a device for improving the reliability of a combined heavy-duty sliding linear guide rail of 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 perform reciprocating linear motions in a given direction. They are used in linear reciprocating motions, have higher rated loads than linear bearings, and can bear a certain torque at the same time. , 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,...
