A double-sided milling end face boring workstation comprises two coaxially-opposite boring power heads, two coaxially-opposite milling power heads and a hydraulic clamp for clamping a workpiece, wherein the hydraulic clamp is positioned in the middle and is provided with two workpiece clamping stations; the opposite power heads are positioned at two sides of the clamp, and the boring power head and the milling power head which are positioned at the same side are arranged on the same hydraulic sliding table; and a boring combined cutter is arranged on the boring power head, and a milling end face combined cutter is arranged on the milling power head.

By adopting the scheme, the double-side double-station processing workstation is formed by the two groups of oppositely-arranged power heads, so that the two end faces of two workpieces can be simultaneously subjected to end face milling and boring processing, single-station or single-end-face processing can be selected according to requirements, only one clamping position is required to be provided with the workpiece, and the corresponding processing cutter is required to be removed, so that the double-side double-station processing workstation is particularly suitable for the process operation requirements of processing the milled end faces and the rough boring on the same equipment. So as to effectively improve the processing efficiency and meet the actual production needs.

Preferably, the clamp is self-centering by a semi-circular channel shaped clamping member; and the hydraulic clamp is provided with a material supporting block, and the material supporting block is used for assisting in supporting the processed workpiece. The workpiece is lifted to be separated from the material supporting block by the moving motion of the clamping process of the semicircular groove-shaped clamping member when the workpiece is loaded and unloaded, the self-centering process is completed, the manual operation is ensured to be simple, and the requirement of operation skills is reduced.

Preferably, the semicircular groove-shaped clamping member comprises two movable clamping blocks which move towards each other, and the movable clamping blocks are driven to move by a clamping hydraulic cylinder. The automatic control is realized by utilizing hydraulic power and a mature hydraulic control technology, so that the automation degree is improved; is particularly suitable for processing circular shaft workpieces.

Preferably, the movable clamping block is fixedly arranged on the clamping seat, the clamping seat is fixed on the clamping slide rail, and the clamping slide rail is connected with the clamping hydraulic cylinder. The reliable operation path of the movable clamping block is ensured, so that the repeatability of the positioning precision of the workpiece in the clamping state is ensured.

Preferably, the hydraulic fixture is arranged on the fixture sliding table, the fixture sliding table is of a hydraulic sliding table structure, and the fixture sliding table is arranged on the fixture base. The power head part is convenient to manufacture, the manufacturing efficiency of equipment is improved, and meanwhile, the maintenance is convenient.

Preferably, each of said power heads is driven by a separate motor. So as to avoid mutual influence and ensure reliability.

The invention has the advantages that the end face milling and boring on the double faces of the circular shaft workpiece can be simultaneously carried out, the processing efficiency is high, the actual production requirements can be met, and the automation degree is high.
