TL;DR: The integral portal type machine tool body has the advantages of compact structure, small floor area, high rigidity, convenient processing, low deformation lability, high precision retaining capacity, short production cycle and low cost; and is especially suitable for machine tools for processing turbine blades and other small-sized parts.
Abstract: The utility model discloses an integral portal type machine tool body, which comprises a machine tool body (10) and a portal frame (20). The machine tool body (10) and the portal frame (20) are combined to form an integral body. Two X-direction X-axis guide track mounting surfaces (1) are arranged at the upper end of the portal frame (20), and an X-axis component mounting groove is formed between the two X-direction X-axis guide track mounting surfaces (1). A U-shaped structure is arranged in the side surface direction at the upper part of the portal frame (20). A tool storage mounting hole (2) is arranged on the portal frame (20). A cuttings chute (8) is arranged inside the machine tool body (10), and a cuttings hole (5) is arranged on the machine tool body (10) and has one end thereof communicated with the cuttings chute (8) and the other end thereof communicated with the outer side of the machine tool body (10). The integral portal type machine tool body has the advantages of compact structure, small floor area, high rigidity, convenient processing, low deformation lability, high precision retaining capacity, short production cycle and low cost; and is especially suitable for machine tools for processing charging turbine blades and other small-sized parts.

TL;DR: In this article, a hydraulic pressure telescopic portal frame type drilling rig is proposed, where a drill pipe is connected with a power source output shaft, the power source is fixed on a power combinational frame, the sliding block frame was connected with the portal frame by a sliding rail pair, and the lifting mechanism was fixed on the chassis of a motor vehicle.
Abstract: The utility model mainly aims to provide a drilling rig which does not change the drill pipe with good stability. The utility model is a hydraulic pressure telescopic portal frame type drilling rig; a drill pipe is connected with a power source output shaft; the power source is fixed on a power combinational frame; the power combinational frame is fixed on a sliding block frame; the sliding block frame is connected with the portal frame by a sliding rail pair; the portal frame is fixed on a lifting mechanism; the lifting mechanism is fixed on the chassis of a motor vehicle; the upper part of the lifting mechanism and the upper part of the sliding block frame respectively are fixed on the two ends of the traction string; the traction string is surrounded on a traction string wheel on the top of the portal frame. The key point of the utility model is that the stable sliding principle of the lifting fork vehicle arm mechanism of the prior technology is applied and a dismountable coupling is mounted between the drill pipe and the power source output shaft. Compared with the prior technology, as a long journey drill pipe is applied, the repeated replacement of the drill pipe and the repeated regulation of the aligned stake number are avoided.
