Automatic drilling machine for flow collecting pipe

Abstract

The invention relates to pipeline drilling machining, in particular to an automatic drilling machine for a flow collecting pipe. The automatic drilling machine comprises a machine frame; the machine frame is provided with a clamping swinging mechanism, a drilling mechanism, an auxiliary clamping mechanism and an auxiliary positioning mechanism, wherein the auxiliary clamping mechanism is located on the other side of a pipeline workpiece clamped by the clamping swinging mechanism and can move on the machine frame in the length direction of the pipeline workpiece, and a first auxiliary clampingmechanism body is provided with a pressing assembly capable of being pressed on the outer surface of the pipeline workpiece; and the auxiliary positioning mechanism is located on a bent section whichis on one side of the auxiliary clamping mechanism and used for supporting the pipeline workpiece, the auxiliary positioning mechanism comprises a supporting plate and a driving mechanism for drivingthe supporting plate to rotate, and after the driving mechanism drives the supporting plate to rotate, the bent section can be rotated along with the pipeline workpiece. During pipeline workpiece installation, one end of the pipeline workpiece is clamped and positioned through the clamping swinging mechanism, the bent part at the other end of the pipeline workpiece is positioned through the auxiliary positioning mechanism, the whole pipeline workpiece can be located on the horizontal plane, and accordingly the drilling machining quality is improved.

Description

【Technical field】 [0001] The invention relates to pipeline drilling, in particular to an automatic drilling machine for collecting pipes. 【Background technique】 [0002] At present, the drillers of some headers usually weld the pipe fittings at both ends at 90 degrees before drilling, and the general drilling machine usually only clamps one end of the pipe fittings for positioning. For the pipe fittings welded at 90 degrees, Because the bending section welded at the rear end affects the position of the center of gravity of the entire pipe, it is difficult to maintain the level of the pipe simply by clamping and positioning at one end, which will affect the position accuracy of the drilling and affect the quality of the drilling. 【Content of invention】 [0003] In order to solve the problem of unstable positioning of pipe fittings welded at 90° in the prior art, the present invention provides an automatic header drilling machine with a relatively simple structure.
