Problems solved by technology

In the current existing technology, there is no U-drill group formed by combining multiple U-drills at close distances at the same time. For porous workpieces that must be processed by U-drills, they can only be processed one by one. This processing method still cannot meet the requirements. High efficiency and high quality work requirements

Abstract

The invention relates to a multi-spindle U drill gang spindle box and a U drill gang high-speed numerical control drilling machine. The spindle box comprises a box body, a bracket and a motor, wherein at least three layers of supporting walls are arranged vertically in the box body; more than three U drill spindles are respectively arranged in an axle hole of each supporting wall horizontally through a corresponding roller bearing; meanwhile, two side walls of the axle hole of each U drill spindle are respectively provided with a thrust bearing; a cooling mechanism is arranged on the outer end face of the supporting wall closest to a drill bit or the side wall of the box body; the spindle box also comprises auxiliary spindles driven by the U drill spindles; and each spindle and each auxiliary spindle are matched, meshed and in transmission connection through a corresponding layer gear. The drilling machine comprises a machine tool base, a transverse slide table, a longitudinal slide table, a water cooling mechanism, a scrap receiver and the multi-spindle U drill gang spindle box. The invention realizes multi-spindle U drill high-speed high-efficiency drilling processing, can ensure positional accuracy of holes, improves hole processing finish, prolongs the service life of a tool, reduces processing cost in a different form, improves the processing efficiency and the durabilityof the tool, and is innovation in the field of modern high-efficiency special machine tools.

Description

technical field [0001] The invention relates to a high-efficiency multi-axis drilling machine tool, in particular to a multi-axis U-drill group spindle box and a U-drill group high-speed numerical control drilling machine. Background technique [0002] In the traditional machining of hole systems, twist drills and group drills can be widely used in radial drills, vertical drills, multi-spindle combined drilling machines, and even hand electric drills because of their simple structure and low cost. However, with the rapid development of modern mechanical processing to high-speed, high-efficiency, and composite processing, the drilling of composite materials and materials that are difficult to process such as high hardness and high strength has been fundamentally changed due to the invention of the U drill. A twist drill is a tool that drills a circular hole in a workpiece by rotating it relative to a fixed axis. Compared with twist drills, the advantages of U drills are: 1. ...
