Gun drills of deep-hole digital controlled drilling machine

Abstract

The invention discloses gun drills of a deep-hole digital controlled drilling machine. In order to meet the requirement that the deep-hole digital controlled drilling machine adopts a horizontal typesingle-row drilling machine for machining, due to the fact that a circular mold workpiece is arranged axially, the gun drills are circumferentially and uniformly distributed along a to-be-machined surface of the circular mold, and each gun drill comprises a guide rail, a gun drill body and a guide arm; the gun drills comprise electric main shafts and drill heads, the electric main shafts are arranged in electric shaft installing bases, the electric main shaft installing bases are arranged between the guide rails and the guiding arms, and the output ends of the electric main shafts are coaxially connected with the drill heads. The gun drills adopt the independent drill heads, the design of a single-gun drill body and double-drill heads in the prior art is improved, the drill heads can be radially distributed along the circular mold, every two adjacent independent drill heads are in acute angle distribution, in the process of machining the circular mold, radial and circumferential machining can be conducted synchronously, and compared with a traditional mode that the drill heads longitudinally machine the circular mold axially, the efficiency of the gun drills is higher.

Description

technical field [0001] The invention relates to the field of deep hole numerical control drilling machines, in particular to a gun drill for deep hole numerical control drilling machines. Background technique [0002] Ring die pellet machine belongs to feed pelletizing equipment. It is a feed processing machine that directly compresses pellets from crushed materials such as corn, soybean meal, straw, grass, and rice husk. Ring die pellet mill is the main feed mechanical equipment for pellet feed production. Its performance determines the feed processing output to a large extent, and occupies a very important position in the feed processing process. Among them, the most important part of the ring die granulator is the ring die, but the drilling process of the ring die is very difficult. In the early days, manual drilling is used, and each hole needs to be manually drilled one by one, and the processing efficiency is extremely low. [0003] The existing drilling machine for ...

Problems solved by technology

Among them, the most important part of the ring die granulator is the ring die, but the drilling of the ring die is very difficult. Manual drilling is used in the early stage, and each hole needs to be manually drilled one by one, and the processing efficiency is extremely low.

[0003] The existing drilling machine for ring die processing is a four-head gun drill horizontal processing. During the processing, the ring die is placed axially and horizontally. A group of gun drills are arranged symmetrically on both sides of the ring die workpiece. The two drill bits of each group of gun drills are parallel to the front and back. Therefore, there will be places that cannot be processed in the process of processing ring die holes, so single-row drills are required for processing
