Self-clamping mechanism

Abstract

The invention relates to a clamping apparatus. The clamping apparatus comprises a support and a clamping element. The clamping member has a surface a in sliding confronting engagement with the support surface A, and a second surface b for engaging the surface of an object to be clamped by the mechanism. The first and second surfaces of the clamping member are disposed at a predetermined angle, theta, is defined by inequality (K+tan(theta)) / (1+Ktan(theta)) is less than or equal to M, formula M represents coefficient of friction of rest between fastening motion element and clamped object, K represents a coefficient of friction of rest between fastening motion element and A supporting plane. The clamping apparatus can clamp objects regardless of static, motility or force of impact applied to the objects, and the clamping apparatus does not require or scarcely require applying energy and not happen exorbitance fastening motion or clipping loosely objects. The clamping apparatus can be extensive use in mechanical layout, machining and manufacturing sector, also can be use in rail facility, bridge and farmery field.

Description

【Technical field】 [0001] The invention relates to a clamping device, in particular to a clamping device for fastening or connecting objects, which can be widely used in mechanical design, processing and manufacturing, and can also be applied and promoted in fields such as railways, bridges and buildings. 【Background technique】 [0002] Clamping devices have been widely used to fasten or connect objects. The previous clamping devices all need to apply an external force to maintain the clamping force acting on the clamped object, and all previous clamping devices have a common disadvantage: when the external force on the clamped object increases to a certain value, the object will fall It will slide out of the clamping device by itself. At this time, the rough clamping surface usually used on the clamping device often damages the surface of the clamped object, and because the minimum clamping force required by the clamped object is usually unable to be estimated in advance, it...

Problems solved by technology

The previous clamping devices all need to apply an external force to maintain the clamping force acting on the clamped object, and all previous clamping devices have a common disadvantage: when the external force on the clamped object increases to a certain value, the object will fall It will slide out of the clamping device by itself. At this time, the rough clamping surface usually used on the clamping device often damages the surface of the clamped object, and because the minimum clamping force required by the clamped object is usually unable to be estimated in advance, it is necessary to clamp the object Often the clamping device exerts excessive clamping force on the object

Therefore, previous clamping devices not only required the use of a large amount of energy, but were only effective to a limited extent
