Get up, 1 head end end face of outer barrel is equipped with datum line corresponding with the scale marking, i.e., boring ought be needed to have the cone of a certain taper
When shape hole, it is only necessary to looser a bolt, it is solid to tighten bolt when indicating that the marking of the taper is at datum line for rotary guide sleeve 2
It is fixed.
The course of work of the invention is as follows：
By taking TBW850 slurry pump head valve seats as an example, 5 degree 42 points of TBW850 slurry pump head valve seats taper, outer barrel 1
It is 2 degree that head end end face, which is with the angle number of degrees α of vertical direction, and the tail end end face of guide sleeve 2 is the angle number of degrees β with vertical direction
It it is 4 degree, at this point, the angle number of degrees being oriented between axially bored line and boring spindle axis are adjustable within the scope of 2 degree~6 degree；
This tooling is mounted on horizontal boring machine (boring machine model TX6213A), taper shank 12 is inserted into 10 taper hole of boring spindle
Interior and fixed, outer barrel 1 is bolted with boring machine terminal pad 7, and 5 degree 42 points are indicated on rotary guide sleeve 2 to guide sleeve 2
The marking is at datum line, and the angle between the axis of pilot hole 9 and boring spindle axis is 5 degree 42 and divides at this time, and pilot hole 9 limits
Angle between 5 axis of knife bar and 10 axis of boring spindle processed is also 5 degree 42 points, tightens bolt, at this time guide sleeve 2 and outer barrel
1 is fixed together, guide sleeve 2 and outer barrel 1 only rotate with boring machine terminal pad 7 (boring spindle 10 of horizontal boring machine with
Terminal pad 7 rotates together), and knife bar 5 while line rotates centered on by 10 axis of boring spindle by boring machine master
The flexible drive of axis 10, knife bar 5 do stretching motion under the limitation of oblique pilot hole 9 according to the angle adjusted, and then with moving knife
First 6 on workpiece 17 boring go out bellmouth.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection domain within.
