Detailed Description
The invention is described in further detail below with reference to the following figures and specific examples: the present application is further described by taking this as an example.
The optimal mode of the double-gun deep-hole gun drill is to drill holes by using a double-drill mode, namely, a left drill bit and a right drill bit simultaneously, so as to improve the processing efficiency. Because the holes in odd rows and the holes in even rows on the workpiece are not in the same straight line along the X axis and are staggered by half the hole distance, the left drill bit and the right drill bit cannot respectively drill the holes in odd rows and the holes in even rows, and the left drill bit and the right drill bit can only simultaneously drill the holes in odd rows or the holes in even rows.
Example 1
As shown in fig. 3, when the total number of rows of workpieces is 8, the number of holes in each row is equal, and according to the algorithm rule of the optimal processing mode of the double-gun deep-hole gun drill, it is obvious that the most reasonable drilling mode is that the distance between the left drill bit and the right drill bit is 4 times of the row distance, so that when the left drill bit is aligned to the first row, the right drill bit is aligned to the 5 th row, and after the left drill bit and the right drill bit complete all drilling of the 1 st row and the 5 th row simultaneously, the left drill bit and the right drill bit are aligned to the 2 nd row and the 6 th row respectively. Complete all drilling of 2 nd row and 6 th row simultaneously, the reason, about the drill bit can accomplish 3 rd, 7 th row simultaneously, 4 th, 8 th row's all drilling, totally carried out four rounds of drilling, the time spent is equivalent to the time of drilling 4 rows of holes.
Example 2
As shown in fig. 4, when the total number of rows of workpieces is 11, the number of holes in each row is equal, according to the algorithm rule of the optimal processing mode of the double-gun deep-hole gun drill, the most reasonable drilling mode is that the distance between the left drill bit and the right drill bit is set to be 6 times of the row distance of the holes, so that when the left drill bit is aligned to the 1 st row, the right drill bit is aligned to the 7 th row, and similarly, after all drilling of the 1 st row and the 7 th row is completed, all drilling of the 2 nd row, the 8 th row, the 3 rd row, the 9 th row, the 4 th row, the 10 th row and the 5 th row and the 11 th row can be completed, finally, one drill bit is removed, and drilling of the 6 th row is completed by adopting a single drilling mode, so that 6 rounds of drilling time are performed, and.
Example 3
As shown in fig. 5, when the total number of rows of workpieces is 8, the number of holes in the same odd rows is not equal, the holes in the 1 st row can be excluded to form the condition that the holes in the odd rows are all equal, according to the algorithm rule of the optimal processing mode of the double-gun deep-hole gun drill, the distance between the left drill bit and the right drill bit is set to be 4 times of the row distance of the holes, 4-round drilling processing of the 1 st, 5 th, 2 nd, 6 th, 3 rd, 7 th and 4 th, 8 th rows is completed, finally, one drill bit is removed, one drill bit is used for completing drilling processing of the holes in the 1 st row in a single drilling mode, and 5-round drilling is performed in total.
The above description is only for the purpose of creating a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
