Multi-axis drill machine tool for machining crankcase side threaded bottom hole and its machining method

Abstract

The invention discloses a multiple-shaft drill bit machine tool for processing a threaded bottom hole in the side surface of a crank case and a processing method thereof. The multiple-shaft drill bit machine tool comprises a workpiece mounting table and a multiple-shaft drill head, wherein the crank case is fixed on the workpiece mounting table, and bottom hole drilling is performed to a thread of the side surface of the crank case through the multiple-shaft drill head. The invention provides a production machine tool with a better effect, the defects that position accuracy of drilling the thread of the side surface of a gear case in the conventional production is difficult to ensure, the processing efficiency is low, the labor intensity is large and the like are overcome, the drilling position accuracy is improved and stabilized, the frequency of drilling is reduced, and meanwhile, the multiple-shaft drill bit machine tool can displace manual operation through a numerical control mode, improves the machine productivity, lowers the labor intensity, remarkably improves the whole production efficiency, saves the total cost, and can efficiently propel the development of the prior art.

Description

technical field [0001] The invention relates to the technical field of crankcase processing technology, in particular to a multi-axis drill machine tool for processing crankcase side threaded bottom holes and a processing method thereof. Background technique [0002] In the existing field of processing and drilling, the process method of radial drilling machine is usually used, that is, put the parts on the special tooling, then put on the drilling mold, then lock the parts with the pressure plate, and finally manually operate the drilling machine for drilling hole. However, due to the lack of flexibility in this method, it is difficult to perfectly meet various production needs. Taking the crankcase as an example, the two side threads need to drill multiple bottom holes, but because conventional drilling instruments generally only have a single shaft , so the holes can only be drilled one by one, and the position of the holes is difficult to meet the technical requirements...

Problems solved by technology

However, due to the lack of flexibility in this method, it is difficult to perfectly meet various production needs. Taking the crankcase as an example, the two side threads need to drill multiple bottom holes, but because conventional drilling instruments generally only have a single shaft , so the holes can only be drilled one by one, and the position of the holes is difficult to meet the technical requirements, which is very inconvenient, and will also lead to problems such as high labor intensity and low processing efficiency; It will cause loosening of crankcase workpieces, etc., so it will easily lead to a decline in production quality, increase cost losses, and is not conducive to efficient and economical production
