Abstract

The invention relates to a machining fixture for drilling lever parts, which comprises a fixture body (1), a supporting plate (101) fixedly connected to the upper surface of the fixture body (1) and a vertical plate fixedly connected to the edge of the upper surface of the fixture body (1), a drill plate (4) is arranged at the upper end of the vertical plate, and the drill plate (4) is connected with a drilling mechanism; a first double-end stud (2) is arranged on the clamp body (1), and the first double-end stud (2) is connected with an external control clamping mechanism; a guide groove block (308) is arranged on the clamp body (1), and the guide groove block (308) is connected with a clamping mechanism. Compared with the prior art, six-degree-of-freedom complete positioning of the workpiece to be machined is achieved, the stability of the workpiece in the machining process is guaranteed, and therefore the machining precision and efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of processing fixtures, in particular to a processing fixture used for drilling a lever part. Background technique [0002] In the field of machining fixture technology, tooling fixtures are widely used in factory machining, and workpieces are usually processed by general fixtures to fix the workpiece position to achieve rough machining or finishing of the workpiece. [0003] Lever parts are commonly used parts in the mechanical field. Its function is to transmit driving force, generally including fulcrum, power arm and resistance arm. In different applications, the size and shape of levers are different, and they often need to be processed in different parts, such as punching. Holes, etc., often need to be fixed on the machine tool by lever clamps to avoid low precision due to movement during processing. At present, many lever parts are small in size and complex in structure and shape, and their dimensiona...
