Omni-directional self-adaptive operation mechanism

Abstract

An omni-directional self-adaptive operation mechanism comprises a transmission telescopic rod, a transmission universal joint, a bearing and an elastic sleeve. An output rotating shaft of a driving device is connected with one end of the transmission universal joint, the other end of the transmission universal joint is connected with one end of the transmission telescopic rod, and a working head is mounted at the other end of the transmission telescopic rod. The transmission telescopic rod is sleeved with the elastic sleeve. One end of the elastic sleeve is arranged on the driving device, and the bearing is arranged at the other end of the elastic sleeve. The bearing is mounted at the end, connected with the working head, of the transmission telescopic rod. The whole operation mechanism can adapt to contact force on a workpiece in the operation process, and thus it is ensured that the working head is in flexible contact with the workpiece in the whole operation process, the operation effect can be improved, and the effect of protecting the workpiece is achieved. The device lowers the requirements for precision in the feeding and transmission aspects of a moving platform, namely the good effect can be achieved by using the moving platform with general processing precision, and therefore the cost performance of whole equipment is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an omnidirectional self-adaptive operation mechanism. Background technique [0002] Mechanical polishing is a polishing method that removes the polished convex part by cutting and plastic deformation of the material surface to obtain a smooth surface. Generally, oil stone strips, wool wheels, sandpaper, etc. are used, and manual operations are mainly used. Special parts such as the surface of a rotating body can be polished. Use auxiliary tools such as turntables. [0003] At present, common polishing devices include round tube polishing machines and plane polishing machines. Round tube polishing machines are mainly used for polishing round tubes, round rods and slender shaft-shaped objects. It is set in a coaxial tandem manner; in the flat polishing machine, there is a polishing method in which the working head is set vertically for point operation, and there is a...

Problems solved by technology

In the surface polishing operation of the polishing machine, although the linear operation is efficient, there is a problem of uneven polishing, and a secondary operation is required; the point operation is better, but most of the existing grinding machine working heads are equipped with grinding at the end. The metal rod made of material has high overall rigidity and no deflection angle and degree of freedom. The working head of this type of grinding machine requires high control precision of the motion platform when processing curved surfaces. That is to say, when the grinding head is dealing with curved surface workpieces, it needs Only with the function of angle self-adaptation can the polishing work of curved surface workpieces be completed with high quality
