Split-type multifunctional deep hole drilling machine

Abstract

The invention relates to a split-type multifunctional deep hole drilling machine. The split-type multifunctional deep hole drilling machine comprises a mechanical power part, an adjustable worktable for a heavy workpiece, a telescopic correction bridge, an inner chip removal hydraulic part and an electric appliance part. By considering the characteristics of the workpiece such as large weight, eccentric deep holes, irregular appearance and particularity of materials, and by sufficiently utilizing the technical advantages of deep hole boring (drilling) and gun drilling, a novel multifunctional deep hole machining device which is more practical is developed and designed.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a split-type multifunctional deep hole drilling machine. Background technique [0002] The ingot holder is the core component of the non-ferrous metal extrusion machine. Its material has high hardness, high temperature resistance, high pressure, and high friction. It is difficult to manufacture and the process is complicated. At present, this part has been basically localized, but compared with imported ones from a technical point of view, there is a certain gap in terms of assembly accuracy and appearance. Taking the eccentric heating hole of the ingot tube as an example, no one can surpass the imported ones at present. Some domestic production enterprises still use traditional vertical drilling machines for processing.

Problems solved by technology

[0002] The ingot holder is the core component of the non-ferrous metal extrusion machine. Its material has high hardness, high temperature resistance, high pressure, and high friction. It is difficult to process and manufacture, and the process is complicated.

At present, this part has been basically localized, but compared with imported ones from a technical point of view, there is a certain gap in terms of assembly accuracy or appearance. Taking the eccentric heating hole of the ingot drum as an example, no one can surpass the imported ones at present.

Some domestic production enterprises still use traditional vertical drilling machines for processing. Drilling) and gun drilling equipment technology cannot meet the processing of eccentric holes, for example: deep hole boring (drilling) is driven by the workpiece, the boring bar also rotates, and must be kept concentric, so eccentric holes cannot be processed

For gun drilling, the workpiece must be fixed on the bed, but the weight of the workpiece itself is tens of tons or hundreds of tons, which is difficult for the equipment to bear. In addition, the adjustment range of the adjustment center of the gun drilling equipment is too small to process eccentricity.
