Abstract

The invention discloses a truss cross beam and a manufacturing method thereof. The truss cross beam comprises a marble truss cross beam body, the marble truss cross beam body is made of a polymer mineral material, the polymer mineral material comprises filler and an adhesive, the filler is composed of cobblestones, basalt and quartz sand of different sizes, the adhesive comprises liquid epoxy resin and a curing agent, and the filler accounts for 66-88% in percentage by mass. The truss cross beam has the damping effect, the procedures of welding, heat treatment and the like are omitted, the efficiency is greatly improved, the cost is saved, and the energy-saving and environment-friendly requirements are met.

Description

Technical field: [0001] The invention relates to the field of truss robots, in particular to a truss beam with a shock-absorbing effect and a manufacturing method thereof. Background technique: [0002] Existing truss beams are welded by square tubes, stress-relieved by heat treatment, and then processed by a series of operations such as drilling and milling in CNC machining centers, and then equipped with line rails and racks and pinions as transmission mechanisms. [0003] Since the existing truss beams are all welded by square tubes, a lot of vibration will be generated during the movement process, and the shock absorption performance is only 1 / 20 of the overall mineral casting truss beams. The existing truss beams have many processing procedures, long processing time, and low efficiency. High and costly, the existing truss beams will cause unstable precision due to the vibration generated during the operation of the mechanical arm, and the traditional rack and pinion tra...
