Centering and clamping tooling

Abstract

The invention provides centering and clamping tooling and relates to the technical field of clamping devices. The tooling solves the technical problem that according to the prior art, a universal clamping tool fails to realize rapid positioning and clamping of a workpiece and the overall height of the clamping tool is high so the machining space of a machine tool is affected. The centering and clamping tooling comprises a base which is provided with a containing groove, a rotating plate which is rotatably arranged in the containing groove, a top plate which is fixedly connected with the base,a clamping assembly which is used for connection with the workpiece in an abutting mode, and a handle which is fixedly connected with the rotating plate; a plurality of guiding grooves are formed in the rotating plate; the first ends of the first guiding grooves are arranged near the edges of the rotating plate; the second ends extend in a curving direction along the circumference of the rotatingplate and gradually near the central axis of the rotating plate; the top plate comprises a platform and a plurality of second guiding grooves which are formed along the axial direction of the top plate; and a plurality of clamping assemblies are respectively arranged in the second guiding grooves and the lower parts of the clamping assemblies can be clamped into corresponding first guiding groovesin a sliding mode. The tooling can be used for rapidly conducting self-alignment centering and clamping of the workpiece.

Description

technical field [0001] The invention relates to the technical field of clamping devices, in particular to a centered clamping tool. Background technique [0002] In the process of CNC machining, most of the workpieces need to be flattened, centered and clamped on the base. These tasks are repetitive and error-prone, and also affect the effective processing time of CNC machining. At present, general-purpose fixtures on the market, such as vises, self-centering vises, and four-jaw chucks, cannot solve the problem of fast positioning and clamping of workpieces in all directions, or the cost is too high. Moreover, the existing four-jaw chuck needs to clamp the workpiece by threading, and its overall height is high, which affects the processing space of the machine tool. [0003] Therefore, it has become an important technical problem to be solved by those skilled in the art how to solve the technical problems that the general-purpose fixture cannot quickly position and clamp th...
