multi-hole drill

Abstract

The invention relates to the field of machining equipment, in particular to equipment for drilling multiple holes simultaneously. The equipment comprises a lathe bed, a radial drilling machine and a multiple-hole synchronization tool, wherein the radial drilling machine and the multiple-hole synchronization tool are mounted on the lathe bed; a gearbox is mounted on the radial drilling machine; the input end of the gearbox is connected with the output shaft of the radial drilling machine; ten drill bit mounting seats are arranged at the output end of the gearbox; the multiple-hole synchronization tool is positioned under the gearbox; the gearbox is connected with the multiple-hole synchronization tool through guide pillars; and ten drilling working positions are arranged on the multiple-hole synchronization tool and in one-to-one-correspondence with the ten drill bits. According to the equipment, the requirement for synchronous drilling and synchronous tapping is met through the cooperation of the gearbox and the multiple-hole synchronization tool and the rotating directions and rotating speeds of all the drill bits are consistent; and unstable impact force in the drilling and tapping process is effectively buffered through springs and spring cylinders on the guide pillars, and the drill bits are prevented from being broken or ejecting out in the deep hole drilling operation.

Problems solved by technology

[0002] There are often many installation holes regularly distributed on the gearbox housing. The work of opening such installation holes on the gearbox housing is single and cumbersome. The existing radial drilling machine equipment can only complete the drilling and drilling of a single installation hole. For tapping work, the operator needs to readjust the position of the workpiece after drilling a hole or drill another hole by controlling the position of the output shaft of the radial drilling machine, which requires a lot of work.

[0003] Special multi-hole drilling equipment has appeared in the production process of the gearbox casing, but due to the unreasonable design of the gear box of this type of equipment, the steering of multiple output shafts is inconsistent, resulting in the phenomenon that the rotation directions of multiple drill bits are inconsistent. As for the fact that this type of equipment needs to be equipped with two types of drill bits to match the inconsistent rotation of the output shaft, for this reason, this type of equipment can only be used for drilling, not for tapping, so as not to cause inconsistent helical directions of threaded holes, giving The installation of the gearbox housing is troublesome

[0004] In addition, the existing multi-hole drilling equipment does not buffer against the force fluctuations in the mechanical drilling and tapping process, so that the drill bit or tap often breaks during multi-hole synchronous operations, and the broken drill bit or tap stays in the gearbox. The casing of the gearbox is scrapped, and if the broken drill bit or tap pops out, it may cause personal injury to the operator
