Clamp with centering function, clamping function and force increasing function

Abstract

The invention discloses a clamp with the centering function, the clamping function and the force increasing function. The clamp with the centering function, the clamping function and the force increasing function is characterized by comprising a pneumatic tendon, a first angle force increasing lever, second angle force increasing levers, length force increasing levers, fulcrums, pressing blocks and a flexible rope, wherein the pneumatic tendon is connected with the first angle force increasing lever through the flexible rope, the first angle force increasing lever is hinged to the second angle force increasing levers on the two sides of the pneumatic tendon respectively in the mode that certain angles are formed between the first angle force increasing lever and the second angle force increasing levers, the second angle force increasing levers are hinged to the length force increasing levers respectively on the two sides of the pneumatic tendon, the length force increasing levers are provided with the fulcrums, and the length force increasing levers are hinged to the pressing blocks respectively on the two sides of the pneumatic tendon. According to the clamp with the centering function, the clamping function and the force increasing function, centering, force increasing and clamping of a workpiece are achieved according to the mechanical principles of the pneumatic tendon and the levers by means of the principle that the output force of the pneumatic tendon is large and the angle force increasing and length force increasing can be achieved through the levers, environmental friendliness is achieved, and the structure is simplified.

Description

technical field [0001] The design relates to a centering clamping force-increasing fixture, which belongs to the technical field of machining. Background technique [0002] In the field of machining, pneumatic or hydraulic power is often used as the clamping power for workpiece clamping. However, hydraulic power will cause liquid leakage and pollute the environment. Pneumatic power is often loud and produces noise pollution. In the case of high clamping force, since pneumatic and hydraulic power cannot be self-increased, the cylinder body is often enlarged, which not only increases the occupied area, but also brings inconvenience to the processing under many processing conditions. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the purpose of this design is to provide a centering clamping booster fixture. According to the mechanical principle of the pneumatic muscle and the lever, the output force of the pneumatic muscle is large a...

[0002] In the field of machining, pneumatic or hydraulic power is often used as the clamping power for workpiece clamping. However, hydraulic power will cause liquid leakage and pollute the environment. Pneumatic power is often loud and produces noise pollution. In the case of high clamping force, since pneumatic and hydraulic power cannot be self-increased, the cylinder body is often enlarged, which not only increases the floor space, but also brings inconvenience to the processing under many processing conditions.
