Fixed gantry stand of high-depth automatic drilling machine

Abstract

The invention discloses a fixed gantry stand of a high-depth automatic drilling machine, comprising a machine seat connected with a stand; and the stand is provided with a fastening mechanism which is fixedly connected with a power head. The fixed gantry stand is characterized by comprising a vertical plate and a transverse plate which are vertical to each other and fixedly connected; the vertical plate is fixed on the machine seat; the fastening mechanism comprises a fastening hole formed in the transverse plate; and the power head is arranged in the fastening hole in which a locking mechanism is arranged. The technical scheme has remarkable advantages and beneficial effect that: firstly, the invention is mainly applicable for keeping the aperture in the same center and unchanged during automatically drilling deep holes; secondly, the structure is especially simple, the engine seat is respectively and fixedly connected with the vertical plate and the transverse plate, the mounting is reliable and the movement and the debugging are not needed; and thirdly, the fastening hole is directly punched in the transverse plate and used for mounting the power head, the mechanism is simple and the operation is simple.

Description

technical field [0001] The invention relates to a drilling machine tool, in particular to a fixed gantry frame of a high-depth automatic drilling machine, and belongs to the field of machine tools. Background technique [0002] The drilling machine is a hole processing machine tool, which can be divided into radial drilling machine, vertical drilling machine, horizontal drilling machine and so on according to its different structure. The radial drilling machine is connected by the rocker arm to the parallel power head (the power head is installed with the drill bit) and the frame. The rocker arm can rotate 360° around the column, and can also rise and fall along the column. The headstock can move along the horizontal guide rail of the rocker arm. , align the workpiece by moving the power head, which is suitable for processing large workpieces, but because the center of force of the power head and the center of gravity of the frame are not on the same line, that is, there is ...

Problems solved by technology

The radial drilling machine is connected by the rocker arm to the parallel power head (the power head is installed with the drill bit) and the frame. The rocker arm can rotate 360° around the column, and can also rise and fall along the column. The headstock can move along the horizontal guide rail of the rocker arm. , align the workpiece by moving the power head, which is suitable for processing large workpieces, but because the center of force of the power head and the center of gravity of the frame are not on the same line, that is, there is an offset between the two, so when drilling deep holes When drilling, not only the rocker arm will tremble, but the power head will tilt, and the hole will be tilted, so it is not suitable for drilling deep holes; the center of force of the power head of the existing vertical drilling machine and the frame (used to fasten the power he
