Multi-hole drilling transmission mechanism

Abstract

The invention relates to a multi-hole drilling transmission mechanism which can be used for processing a plurality of holes at the same time, belonging to the technical field of machining; the multi-hole drilling transmission mechanism comprises an upper plate, a middle plate and a lower plate, wherein a plurality of drilling rod shafts are respectively and rotatablely supported on the middle plate and the upper plate; the drilling rod shafts are respectively and fixedly provided with a drill bit; the lower plate is provided with drilling rod holes, and the drill bits can respectively and conveniently pass through the drilling rod holes in a corresponding way; the middle plate and the upper plate are also respectively provided with a plurality of support sleeve mechanisms which are used for relatively fixing the upper plate and the middle plate; the lower plate is provided with a plurality of guide pillars which are respectively and correspondingly matched with inner holes of the support sleeve mechanism up and down in a sliding way; two hollow shaft sleeves are respectively and rotatablely supported at the centers of the middle plate and the upper plate; two thread guide sleeves which are respectively sheathed in the hollow shaft sleeves in a matching way and can synchronously rotate together with the hollow shaft sleeves are rotatablely supported on the lower plate; a lifting screw rod shaft matched with the thread in each thread guide sleeve passes through each hollow shaft sleeve; the upper ends of the lifting screw rod shafts are connected with the upper plate in a rotary support way; the hollow shaft sleeves are connected with the drilling rod shafts by a main transmission mechanism in a transmission way; and hollow shaft sleeves are connected with the lifting screw rod shafts by a feeding mechanism in a transmission way.

Description

technical field [0001] The invention relates to the field of drilling equipment, in particular to a special multi-hole drill transmission mechanism capable of processing multiple holes at the same time. Background technique [0002] In mechanical cutting processing, drilling processing is quite extensive. In the existing technology, when the drilling processing of porous parts is processed by a drilling machine, generally only one hole can be processed at a time. Clamping and fixing and drilling processing, manual scribing and clamping are time-consuming and inefficient, and the scribing accuracy is completely controlled by people, which not only affects the processing accuracy but also increases the labor intensity of workers, and the production efficiency is very low. Contents of the invention [0003] The invention aims at the problems existing in the prior art, and provides a multi-hole drill transmission mechanism capable of simultaneously drilling and processing a pl...
