What are the manipulators
The types of manipulators can be divided into hydraulic, pneumatic, electric and mechanical manipulators according to the driving mode, and can be divided into special manipulators and general manipulators according to the scope of application. according to the motion trajectory control mode can be divided into point control and continuous trajectory control manipulator and so on. Manipulators are usually used as additional devices for machine tools or other machines, such as loading, unloading and transferring workpieces on automatic machine tools or automatic production lines, changing tools in machining centers, etc., generally there is no independent control device.
Is it a truss, a truss, a quilted frame or a truss?
It’s a truss.
The word “truss” pronounces “h é ng”. Because the word “truss” is seldom used, it is mispronounced as “h á ng” (line), hence the name “rack”. Definition of truss: a braced beam structure formed by welding, riveting or bolting of members, which is called “truss”.
Truss (h é ng) frame (Jià) (truss): a structure consisting of members hinged to each other at both ends. The truss is a plane or spatial structure composed of straight bars with triangular elements. the truss members mainly bear axial tension or pressure, so that the strength of the material can be fully utilized, and the material can be saved compared with the solid web beam when the span is large. reduce self-weight and increase stiffness.
Extended data:
In general, the following effects should be taken into account when meshing tube truss structures:
1. The influence of the position of the support point on the grid:
It can also be said that the support point is different in different projects, which can be placed on the upper chord of the truss or on the lower chord of the truss. In the steel structure project, as there are cantilevers all around, it is more reasonable to put the upper chord through the supporting point on the lower chord. Then, when meshing, we should at least ensure that there are corresponding nodes in the position of the support point.
2. Make sure that the angle between the members is not too small.
This problem can refer to the “Technical Specification for Spatial Grid structure” JGJ 7-2010 to determine the size of the grid or grid, so that the angle between the adjacent members is more than 45 °and not less than 30 °.
3. The rationality of the arrangement of substructures.
In general, the roof panel should transfer the self-weight to the truss main structure through the secondary structure of purlin. in order to transfer force directly and minimize the path, the span of the secondary structure should be controlled within a reasonable range when arranging the tube truss structure. In general, the span of light steel roof purlin can be controlled between 1.5 and 4m.

What is the structural composition of the truss manipulator?
The truss bai manipulator consists of six parts: structural frame, X-axis assembly du, Y-axis assembly, Z-axis assembly, fixture and control cabinet.
Structural frame, mainly composed of columns and other structural members
X-axis assembly, Y-axis assembly and Z-axis assembly are usually composed of structural members, guide parts, transmission parts, sensor detection elements and mechanical limit components.
This is the end of the introduction of the picture of the truss manipulator and the working principle of the truss manipulator. I wonder if you have found the information you need? If you want to know more about this, remember to collect and follow this site.
