Problems solved by technology

[0006] 1. The holes are arranged in rows and columns;
[0007] 2. Many holes and dense;
[0008] 3. The hole is small;
[0015] 2. How to determine the distance between adjacent spindles when there are many spindles?
[0018] For questions 2 and 3, the current method is to obtain the results through a large number of calculations by the designer, which leads to cumbersome design and calculation work for multi-head drilling machines and a long design cycle
In use, when the calculation is not essential, the operator often uses partitions and slices to drill holes instead of drilling holes row by row, and the drilling efficiency is low.

Abstract

The invention discloses a determination method of a spindle space and a drilling mode of multi-spindle numerical control sieve plate drilling equipment. The method is characterized by comprising the following steps: 1, defining known parameters: drilling region width range W, adjacent hole maximum space Xm, spindle external diameter D and adjacent spindle minimum gap Y; 2, trialing and determining large-step drilling frequency N and adjacent spindle space L, wherein the formula is N=(2W+Xm) / 2ML(1)L>D+Y(2); solving the large-step drilling frequency N and adjacent spindle gap L according to the equation (1) and the inequality (2), wherein N is rounded off to be an integer, L is the minimum value of the inequality; 3, determining small-step drilling frequency n in each big step and final hole space X, wherein the formula is L=nX(3); X is less than or equal to Xm; (4) trialing according to the equation and the inequality and solving the small-step drilling frequency n in each big step and the finally determined drilling space X, wherein n is decimal which is rounded off to be an integer; X is the maximum value meeting the inequality.
