Clamp for processing a plurality of slender holes on workpiece and processing method thereof

Abstract

The invention relates to a clamp for processing a plurality of slender holes on a workpiece, belonging to machining technical field. A bottom plate (1) and a side plate (2) are in L-shaped; a stud bolt (5) is fixedly arranged in the middle of the bottom plate (1), and a spring (8) is sheathed on the stud bolt (5); the upper part of the stud bolt (5) is respectively provided with a pressure plate (6) and a nut (7); a guide pin (4) is arranged on one side of the stud bolt (5) on the bottom plate (1), and a positioning pin (3) is arranged on one side of the side plate (2). The invention fixes a workpiece by the simple clamp. Processing carried out on the existing high-cost horizontal processing center is changed for processing carried out on low-cost digital-control milling machines or vertical processing center, which reduces equipment investment. The clamp of the invention has simple structure and short production cycle, and therefore, the clamp of the invention is suitable for product processing with small lot, wide varieties and short development cycle. The invention has the advantages of reasonable design, simple method and the like.

Description

technical field [0001] The invention belongs to the technical field of machining, and in particular relates to a fixture for machining a plurality of elongated holes on a workpiece and a machining method thereof. Background technique [0002] At present, due to the progress of society, various products are constantly being updated, so the precision requirements for workpieces are getting higher and higher. Taking the automobile industry as an example, the product update is very fast; in the processing of the automotive industry When producing products, multiple slender through holes are often processed on one surface, and the hole diameter and coaxiality have high requirements, and the distance between holes is very small, which cannot be processed by multi-axis special machines; Machine tool processing cannot meet the requirements. In this case, most manufacturers use horizontal machining centers to process both ends of the rotary table, or use flip fixtures to process on v...

AI Technical Summary

Problems solved by technology

The flip fixture is used to process on the vertical machining center, because the design and processing costs of the flip fixture on the machining center cost about 80,000 to 100,000 yuan, and the design and processing time takes about two months, which is not suitable for the current situation. Diversified, fast-paced, and low-cost processing requirements for the automotive industry and products with long and thin holes
