Embodiment Construction

[0008] Referring to the accompanying drawings, a special fixture for triangular pyramid processing includes a base (1), a positioning index plate (2), a clamping block (3), a positioning pin (4) and a bolt (5). A positioning surface, a positioning hole, a positioning index plate mounting hole, and a clamping block mounting hole are arranged on the base (1), and a positioning hole and a workpiece blank mounting hole are arranged on the positioning index plate (2). The base (1) is fixed on the machine tool table. The positioning index plate (2) is connected with the workpiece blank by bolts (5), so that the positioning index plate (2) and the workpiece blank are fixed. The positioning index plate (2) fits with the positioning surface on the base (1), and the stepped shaft on the positioning index plate (2) is put into the mounting hole of the positioning index plate on the base (1), so that the positioning index The disk (2) can rotate on the positioning surface of the base (1)...

Abstract

The invention relates to a special clamp for machining a triangular pyramid. The special clamp comprises a base, a positioning index plate, a clamping block, a positioning pin and bolts, wherein the base is fixedly arranged on a machine tool work bench; the positioning index plate is connected with a workpiece blank through the bolts; the positioning index plate is attached to a positioning surface on the base; a stepped shaft on the positioning index plate is arranged in a positioning index plate mounting hole in the base; and the rotational degree of freedom of the positioning index plate is limited through the positioning pin inserted in a positioning hole in the base and a positioning hole in the positioning index plate; the clamping block is connected with the base through the bolts; and the axial degree of freedom of the positioning index plate is limited by the clamping block pressing the positioning index plate so that the whole workpiece is fixed. The special clamp is reasonable in structure and convenient to disassemble, thus effectively solving the problems that the triangular pyramid is difficult to clamp, low in machining accuracy and the like when being machined.

Description

technical field [0001] The invention and the technical field of fixtures specifically belong to a special fixture for triangular pyramid processing. Background technique [0002] At present, casting or machining center milling is usually used for pyramid parts. Some factories first process the cylindrical blank into a triangular prism, and then place the milling cutter at a certain angle for milling. Since the angles of each face of the triangular Clamping is difficult, inaccurate positioning leads to unqualified shape and size of the processed pyramid, and low material utilization rate. Contents of the invention [0003] The object of the present invention is to provide a special fixture for triangular pyramid processing, which has a reasonable structure and is easy to disassemble, and solves the problems of difficult clamping and low processing accuracy in triangular pyramid processing. [0004] In the present invention, bolts are used between the processing blank and t...
