Floating clamping mechanism

Abstract

The invention relates to a floating type clamping mechanism. The floating type clamping mechanism is provided with a working platform and a chuck; a clamping rod is arranged on the bottom surface of the working platform, and the chuck can be connected to the clamping rod of the working platform through a releasing or clamping action; and the chuck comprises a foundation base with an actuation chamber formed in the center, the opening end of the foundation base is fixed to a top base in a locked mode, a piston base is arranged in the actuation chamber of the foundation base, a plurality of elastic parts used for supporting the piston base are annularly arranged between the piston base and the top base, a movable base is arranged in the center of the piston base, an annular inclined surface is arranged on the outer side of the top of the movable base and is limited at the opening of the top base, a movable clamping piece moving horizontally is arranged on the periphery of the movable base, and a bottom base body is arranged at the bottom of the piston base. Thus, the clamping rod of the working platform is embedded into the movable base, the movable clamping piece moves inwards to clamp the clamping rod, the movable base floats upwards, through the action of the annular inclined surface of the movable base and the opening of the top base, the movable base is pushed inwards to downwards press and stably clamp the clamping rod, and the zero clamping effect of the working platform and the chuck is achieved.

Description

technical field [0001] The present invention relates to a floating clamping mechanism, in particular to a floating clamping mechanism that can firmly clamp a work platform so that it does not shake and can ensure the precision of processed products on the work platform. Background technique [0002] For semi-automatic or fully automatic machining, it is very important whether the carrier carrying the workpiece can be clamped in the correct position on the chuck or completely released. For example, if the carrier is not correctly positioned on the chuck, there may be a danger of the position of the workpiece shifting during machining, resulting in inaccurate deviations in the machining dimensional accuracy of the workpiece, and of course it may cause serious damage. [0003] However, generally this type of clamping mechanism is generally a positioning device such as Taiwan Patent Publication No. I455790, which is used to position the object on the X axis, the Y axis perpendic...

Problems solved by technology

However, when the workpiece requires more precise dimensions, the stage (tool) that clamps the workpiece must be kept in a non-shaking processing state. Therefore, the stage (tool) and the clamping device must , it is more necessary to have a high-precision combination design; therefore, when making a clamping device or a stage (tool), the corresponding combination accuracy of the two must be kept below the range of 0.01mm. Cost, labor and time-consuming, its damage rate is also high, and the service life of the clamping equipment or carrier (tool) is short, and the elimination rate is high
