Problems solved by technology

Therefore, the most commonly used method at present is to process the mounting holes one by one, the work efficiency is low, and the machining accuracy cannot be guaranteed well.
Even if a special multi-head drill is used, since the center distance between the multi-drills is fixed and cannot be adjusted, it can only be processed for multiple mounting holes with a certain fixed hole distance.

Abstract

The invention discloses a multi-head drilling machine which is characterized by comprising a shell, a rotating disc, a main power gear and a main regulating gear. The main power gear is in transmission connection with a motor, N auxiliary power gears meshed with the main power gear are evenly distributed on the periphery of the main power gear, the auxiliary power gears are connected with power transmission shafts which are arranged on the rotating disc in a rotatable mode, the rotating disc is arranged in the shell in a rotatable mode, the power transmission shafts are connected with a first gear, the main regulating gear is connected with a regulating rod, N auxiliary regulating gears meshed with the main regulating gear are evenly distributed on the periphery of the main regulating gear, the auxiliary regulating gears are connected with drill rod sleeves which are arranged in the shell in a rotatable mode, eccentric sleeve holes are formed in the drill rod sleeves, the eccentric sleeve holes are used for mounting drill rod shafts which are arranged in a rotatable mode, the drill rod shafts are connected with a second gear, the second gear is meshed with the first gear, and the power transmission shafts are connected with the drill rod shafts through a swing arm. According to the multi-head drilling machine, multi-hole simultaneous machining can be performed on workpieces with different hole distances, machining precision is high, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a drilling machine for simultaneously processing multiple holes. Background technique [0002] At present, parts such as bonnets and flanges generally have multiple (4 or 6 in most cases) mounting holes that need to be processed, and these mounting holes are usually evenly distributed on a certain center distance. , the number of these mounting holes can be the same, but most of the center distances will be different. Therefore, the most commonly used method at present is to process the mounting holes one by one, the work efficiency is low, and the machining accuracy cannot be guaranteed well. Even if a special multi-head drilling machine is used, since the center distance between the multi-drill bits is fixed and cannot be adjusted, it can only be processed for a plurality of mounting hole workpieces with a certain fixed hole distance. Contents of the invention [0003] In view of the shortcomings of the background technol...
