Pipe Drilling Machine

Abstract

The invention provides a pipe fitting drilling machine comprising a machine body, an indexing spindle box disposed at a front end of the machine body to clamp a workpiece, a longitudinal drive system, a carriage disposed above the machine body and capable of sliding along a carriage moving guide rail with a transverse moving guide rail disposed at an upper portion of the carriage, a slide carriage frame located below the carriage and fixedly connected to the carriage, a longitudinal nut in screwing fit with a longitudinal lead screw to form a longitudinal lead screw pair together, a slide plate disposed above the carriage and capable of sliding along the transverse moving guiding rail, a transverse lead screw fixed to the carriage, a transverse nut fixed to the slide plate and in screwing fit with the transverse lead screw to form a transverse lead screw pair together, a transverse servomotor fixed to the carriage and having an output shaft fixedly connected to the transverse lead screw, a drill rod case fixed to the slide plate and used for drilling a pipe fitting, a tailstock assembly disposed at a rear end of the machine body to press against a workpiece, and a workpiece clamping device disposed above the carriage to clamp a workpiece during drilling.

Description

technical field [0001] The invention relates to a mechanical processing equipment, in particular to a pipe fitting drilling machine. Background technique [0002] The pipe wall drilling of pipe parts is generally carried out by marking first and then drilling with a drilling machine. The disadvantage is that the two processes are completed on the marking platform and the drilling machine respectively. During the processing, the workpiece needs to be removed from the marking platform. Transported to the drilling machine, and because the workpiece cannot be automatically indexed, the workpiece rolls many times during the machining process, which not only has low work efficiency, but also poor machining accuracy. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a pipe drilling machine for solving the above-mentioned problems in the prior art. [0004] In order to achieve the abo...
