Embodiment Construction
[0024] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0025] Such as Figure 1-6 As shown, a roller-type guide rail pair for a truss robot of the present invention includes a guide rail 1 and a sliding body 2, and a rolling assembly is arranged inside the sliding body 2, and the rolling assembly includes four sets of roller sets 4, each The slide rail 3 forms a kinematic pair with the two sets of rollers 4 respectively, and each set of rollers 4 has three rollers.
[0026] At least two opposite sides of the guide rail 1 are provided with a slide rail 3 respectively, each slide rail 3 has a mounting surface and three moving surfaces 31, and the mounting surface and the moving surface 31 are all along the length o...

The invention relates to a roller wheel type guide rail pair for a truss manipulator. The roller wheel type guide rail pair comprises a guide rail and a sliding body, wherein a rolling component is arranged in the sliding body and comprises at least two groups of roller wheel sets, each group of the roller wheel sets comprises at least three roller wheels which are connected with the guide rail in a rolling manner respectively, and the moving planes of the three roller wheels, which are connected with the guide rail in a rolling manner, in each group of the roller wheel sets form three side surfaces of a cuboid; and at least one roller wheel in each group of the roller wheel sets is an eccentric shaft roller wheel. By virtue of the roller wheel sets, the original static friction is changed into rolling friction, so that the friction force is reduced, and further, the abrasion between the guide rail and the sliding body is reduced; a joint seam among guide rails can be easily crossed over during rolling to realize continuity and stability of the sliding body; the contact surface between the roller wheels and a slide rail is relatively large, so that the influence on the guide rail pair caused by impurities is relatively slight; and the calorific value of the roller wheels is small when the linear velocity is increased, so that the service life of the guide rail pair is prolonged.
Description
technical field [0001] The invention relates to a roller type guide rail pair for a truss robot. Background technique [0002] The traditional truss robot uses a sliding connection between the guide rail and the sliding body. This connection method has many disadvantages. First, the sliding body and the guide rail are slidingly connected, and the friction generated is static friction, which causes damage to the guide rail and the sliding body itself. The wear will be relatively large; secondly, the length of the guide rail is limited. A long guide rail is often spliced by multiple shorter guide rails, and a seam will be left at the splicing of the two guide rails. After use, the original relatively small seam will become larger, and when one end of the sliding body slides to the seam, it is easy to be stuck by the seam, affecting the normal operation of the sliding body, resulting in device alarms and affecting production efficiency. [0003] In addition, the installation...
