Novel functional flexible clamp and application method thereof

Abstract

The invention relates to a novel functional flexible clamp and an application method thereof. The clamp is characterized in that the clamp comprises a positioning and clamping groove which is used for positioning and clamping parts, a cleaning and recycling groove which is used for cleaning cutting dust and recycling magneto-rheological liquid and a clamp base; the clamp base is used for fixedly installing the positioning and clamping groove and the cleaning and recycling groove, fixed connections between the clamp and all types of machine tool platforms are achieved, and the clamp base comprises a connection baseplate, electromagnets and permanent magnets; the connection baseplate is of a tabular structure which has a flat bottom surface and a protrusion on the middle of the upper surface, U-shaped grooves which are used for achieving the fixed connections between the clamp and all types of the machine tool platforms of are symmetrically formed in the left side and the right side of the connection baseplate, and a plurality of connection through holes which are used for fixing the positioning and clamping groove and the cleaning and recycling groove are formed in the middle of the connection baseplate; a plurality of grooves are evenly formed in the protrusion on the middle of the upper surface of the connection baseplate in the length and width directions of the connection baseplate, and communication grooves which are used for arranging electromagnet cables are formed among the grooves.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a novel multifunctional flexible clamp and its use method. Background technique [0002] With the rapid development of high-end manufacturing industry, the demand for processing multi-variety, small-batch, high-precision and complex parts is becoming increasingly strong. Therefore, higher requirements are put forward for the traditional general-purpose and combined machine tool fixtures: on the one hand, the fixtures must have strong versatility, be applicable to various types of machine tools, and can be used for various materials such as metals and non-metals. processing, to achieve effective positioning and clamping of various complex parts, so as to reduce the development and application of special fixtures; Improve production efficiency; in addition, for some special applications, new specific requirements are put forward for fixtures. For example, in the process of pro...

Problems solved by technology

[0003] In order to meet the development needs of precision, high efficiency and flexibility of modern machine tool fixtures, in response to the above technical problems, a variety of multifunctional flexible fixtures have been developed at home and abroad, such as "Research on Control System of Multi-point Flexible Pneumatic Fixtures Based on Negative Pressure Adsorption" (Lei Weiwei et al., Mechanical Manufacturing, Vol. 55, No. 632, 2017) involves a multi-point flexible pneumatic fixture based on negative pressure adsorption, which uses a modular pneumatic suction cup fixed on the bottom plate of the fixture to achieve vacuum adsorption and support positioning of parts , but in the process of use, according to the structural characteristics and processing needs of different parts, the installation layout of the modular pneumatic suction cups must be adjusted by replacing the mounting holes or the fixture bottom plate to form a reasonable positioning support for the parts. At the same time, the control system needs to control each pneumatic suction cup separately. The adsorption support function of the parts, the operation control is relatively complicated, and the versatility is relatively poor; the patent document "Universal Flexible Fixture and Its Using Method (CN105171479A)" discloses a universal flexible fixture and its using method. The auxiliary cooling device controls the phase change of the low melting point phase change material in the phase change material cavity, adjusts and fixes the positioning bodies and clamping bod
