Description

Circular extension platform

Technical Field

The utility model belongs to the technical field of the vibration test equipment, concretely relates to circular extension platform.

Background

The electric vibration table simulates the working stability and the fatigue resistance of a tested sample under various mechanical environment conditions, because the table top size of the electric vibration table is limited by the structure, the mounting size is not enough when a large sample is tested, a test sample or a clamp can be larger than the movable coil table top of the electric vibration table, so that the original table top needs to be expanded, when the tested sample is larger than the vibration table top, the anti-overturning moment of the vibration table can be improved when a vibration test is carried out, a group of auxiliary guides are arranged on the part of the expanded table top, the anti-overturning moment of the vibration table is improved, and the requirement that the vibration table cannot be damaged when the large sample is tested is met. The conventional method is to use a linear bearing or an approximate structure as an auxiliary guide, but when the mounting surface of the supporting device of the auxiliary guide slightly deviates from the mounting position of the guide shaft of the expansion table surface, namely the mounting position is not parallel, the expansion table accelerates the abrasion of the guide shaft in the movement process, so that the clamping or guide failure of the auxiliary guide is caused, and the normal work and use of the vibration table are influenced, therefore, a circular expansion table capable of damping, preventing the clamping and reducing the abrasion is required.
