Specific implementation mode
The present embodiment is described in detail by taking a kind of deep trouth ears side opening connector workpiece as an example.
It is workpiece to be processed schematic diagram as shown in Figure 1.Workpiece to be processed 1 has semiclosed deep groove structure, has in deep trouth double
Stud, after there are coaxial precision holes 2, the processing of precision holes to be divided into milling processing, accurate Boring, bushing installation for stud side
Accurate Boring three phases, machining tool are right-angle milling head, milling cutter, boring cutter, and process equipment is CNC milling machine.
The auxiliary transverse alignment device for the deep groove side hole digital control processing that the application proposes, as shown in Figure 2.The centering of deep trouth side opening fills
It sets containing there are three parts：T-type centering block 3, alignment pin 4, locking nut 5.
As shown in Figure 3, Figure 4, its shape of T-type centering block 3 is the 20mm uniform thickness slab constructions of T-type symmetrical profiles, and material can
For the common metals material such as steel, aluminium.The bottom front of T-type centering block 3, there is a step through-hole, is located in symmetrical center line.Wherein
Aperture is positioning unthreaded hole 9, is precision holes, and macropore is threaded connection hole 8, and holes is coaxial.The top end surface 6 of T-type centering block is one
Rectangular planes, length are equal to total height of T-type centering block.The plane is perpendicular to the symmetrical center line of T-type centering block, and this is flat
The distance at face to 9 center of positioning unthreaded hole is to determine to be worth, and being more than deep trouth side opening center on workpiece, should to the distance of workpiece peak
The planarity requirements of plane are less than 0.02mm.At the center of top end surface 6, there are an alignment holes 7, is precision holes Φ 10H7, hole depth
The distance of 5mm, hole center to 6 long side of top end surface (side of installation alignment pin) are 10mm.
