Rapid multi-station drilling pipe joint special machine

Abstract

The invention discloses a rapid multi-station drilling pipe joint special machine, and belongs to the field of pipe joint special machines. The special machine comprises a device body, the device bodycomprises three groups of drilling pipe devices, a fixing device and a motor box, the fixing device is connected with the output end of the motor box, each group of drilling pipe devices is arrangedat the top end of the fixing device, each group of drilling pipe devices comprises a rotating motor and a drilling rod, each group of rotating motors is fixed to a ground through a fixing ring arranged on the outer side surface and a mounting column, the mounting columns are arranged on the outer sides of the drilling pipe devices, the output ends of the rotating motors are fixedly connected withrotating shafts, drilling rods are fixed in the middles of the rotating shafts, the bottom ends of the drilling rods on each side are provided with a fixing table, and the fixing device comprises a carrier plate, four groups of fixing tables, blocking rods and air columns. Machining time of a plurality of pipe joints is shortened on the premise of guaranteeing the machining quality, and after eachgroup of pipe joints are machined, subsequent drilling rods can repeatedly carry out drilling the same position at the same height, an inspection function is achieved, and the yield is improved.

Description

technical field [0001] The invention relates to the field of a special machine for pipe joints, in particular to a special machine for fast multi-station drilling pipe joints. Background technique [0002] Pipe joint: a hydraulic term, it is a part that connects the pipeline or installs the pipeline on the hydraulic component in the hydraulic system. The machine is called a special machine, which requires high-precision drilling and engraving of the pipe joints to avoid the risk of leakage during use. [0003] There are the following problems in the use of existing special machines for pipe joint processing: 1. Most of the existing methods for fixing pipe joints are spring clamping or screw thread clamping. Such devices are first in the process of processing , often due to the shaking caused by the rotation of the drill pipe, it will damage the fixed state of the pipe joint, which may affect the accuracy of drilling and engraving; 2. The existing special machines are often ...
