Abstract

The utility model relates to a special clamp for processing a triangular pyramid. The special clamp comprises a base, a positioning dividing disc, clamping blocks, positioning pins and bolts, wherein the base is fixed on a working platform of a machine tool; the positioning dividing disc is connected with a workpiece blank by the bolts and is attached with the positioning surface on the base; a stepped shaft on the positioning dividing disc is arranged in installing holes of the positioning dividing disc on the base, and the rotating freedom degree of the positioning dividing disc is limited by inserting the positioning pins into positioning holes in the base and positioning holes in the positioning dividing disc; the clamping blocks are connected with the base by the bolts, and the axial freedom degree of the positioning dividing disc is limited by using the clamping blocks to press the positioning dividing disc so as to fix the whole workpiece. The special clamp has the advantages that the structure is reasonable, the disassembly is convenient, and the problems of difficulty in clamping and low processing accuracy and the like in processing the triangular pyramid are effectively solved.

Description

A kind of triangular pyramid Special Fixture for Machining
Technical field
The utility model relates to clamp technology field, specifically belongs to a kind of triangular pyramid Special Fixture for Machining.
Background technology
At present, for pyramid class part, conventionally adopt casting or machining center milling, triangular prism is first processed into by cylinder blank in some factories, again milling cutter is placed into certain angle and carries out milling, because each face angle of triangular pyramid is certain, in process, clamping difficulty is large, locate inaccurate the processed pyramidal shape off-dimension that causes, stock utilization is low.
Summary of the invention
The purpose of this utility model is to provide a kind of triangular pyramid Special Fixture for Machining, and it is rational in infrastructure, and convenient disassembly has solved the problems such as triangular pyramid when processing clamping is difficult, machining accuracy is low.
With bolts between machining blanks and locating indexing disc in the utility model, between locating indexing disc and pedestal, adopt shaft hole matching that locating indexing disc can be rotated on base stand location face, by clamp, locating indexing disc is clamped man-hour adding, with bolts between clamp and pedestal, locating indexing disc comes the restricting rotation free degree to reach the effect of location by alignment pin, so before whole workpiece processing and after processing, only need assembling-disassembling bolt and alignment pin can reach the object of handling, convenient disassembly, the problem of clamping difficulty while efficiently solving triangular pyramid processing, in process, on pedestal, locating surface and horizontal plane angulation and triangular pyramid two adjacent surfaces angulation are complementary, on locating indexing disc, three locating holes are uniform, efficiently solve the problem that triangular pyramid machining accuracy is low.
Accompanying drawing explanation
Fig. 1 is part drawing of the present utility model.
Fig. 2 is assembling schematic diagram of the present utility model.
In figure, 1. pedestal, 2. locating indexing disc, 3. clamp, 4. alignment pin, 5. bolt.
The specific embodiment
Referring to accompanying drawing, a kind of triangular pyramid Special Fixture for Machining, comprises pedestal (1), locating indexing disc (2), clamp (3), alignment pin (4) and bolt (5).On pedestal (1), there are locating surface, locating hole, locating indexing disc installing hole, clamp installing hole, on locating indexing disc (2), have locating hole, workpiece blank installing hole.Pedestal (1) is fixing on platen.Locating indexing disc (2) is connected by bolt (5) with workpiece blank, and locating indexing disc (2) and workpiece blank are fixed.Locating indexing disc (2) and the upper locating surface laminating of pedestal (1), the upper multidiameter of locating indexing disc (2) packs in the locating indexing disc installing hole on pedestal (1), and locating indexing disc (2) can be rotated on the locating surface of pedestal (1).The locating hole and the upper locating hole of locating indexing disc (2) that by alignment pin (4), insert on pedestal (1) limit the rotary freedom of locating indexing disc (2).Clamp (3) is bolted with pedestal (1), compresses locating indexing disc (2) limit the axial freedom of locating indexing disc (2) by clamp (3).So far, clamping is complete.Milling is processed along horizontal plane, after processing one side, pull down clamp (3), extract alignment pin (4), rotation locating indexing disc (2) is to next locating hole, load onto alignment pin (4) and clamp (3) carries out lower one side processing, so circulation is until 3 full completion of processing of face.

Claims (1)

1. a triangular pyramid Special Fixture for Machining, it is characterized in that: with bolts between machining blanks and locating indexing disc, between locating indexing disc and pedestal, adopt shaft hole matching that locating indexing disc can be rotated on base stand location face, by clamp, locating indexing disc is clamped man-hour adding, with bolts between clamp and pedestal, locating indexing disc carrys out the restricting rotation free degree by alignment pin, on pedestal, locating surface and horizontal plane angulation and triangular pyramid two adjacent surfaces angulation are complementary, and on locating indexing disc, three locating holes are uniform.
