Specific embodiment
The present embodiment is described in detail by taking a kind of processing 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 numerical 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 construction 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 two holes are 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 positioning 9 center of unthreaded hole is to determine value, and being greater than deep trouth side opening center on workpiece, should to the distance of workpiece highest point
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.
Alignment pin schematic diagram as shown in Figure 5.4 material of alignment pin is steel, is in step shaft-like, is divided into four sections, and four sections same
Axis.First segment 10 is optical axis, is matched with the positioning unthreaded hole 9 of 3 bottom of T-type centering block, diameter is same；Second segment 11 is spiral shell
Line axis is matched with the threaded connection hole 8 of 3 bottom of T-type centering block, and the diameter of second segment is greater than first segment；Third section 12 is light
Axis is matched with deep trouth side opening 2 on workpiece 1, and diameter is same；4th section 14 is thread spindle, is connected with the screw thread of locking nut 5
It connects hole to match, the 4th section of diameter is in third section.
5 material of locking nut is steel, is in circular ring shape, center is threaded connection hole, is connect with alignment pin, outside locking nut
Surface has annular knurl, in order to operate.
Before the centering for carrying out deep trouth side opening, T-type centering block 3 is pre-assembled with alignment pin 4, and T-type centering block
Top end surface 6 (is installed and is determined to top end surface long side to the distance at positioning 9 center of unthreaded hole and the center of top end surface alignment holes 7
Position pin shaft side) distance measure exact value in advance.
The alignment device and aligning method of deep trouth side opening:
As shown in Figure 6,7.Alignment pin 4 is inserted into the deep trouth side opening 2 of workpiece 1, by the stud of T-type centering block 3 and workpiece 1
15 side wall fits closely, and in the other side of workpiece stud, is connect with locking nut 5 with alignment pin 4, and pre-tightened.
An amesdial 14 is fixed on machine tool chief axis, is moved back and forth along 6 length direction of T-type centering block top end surface, leveling
Then top end surface tightens locking nut 5.
Later, using amesdial with machine tool chief axis rotation mode, the center of centering top end surface alignment holes 7, so that it is determined that
Horizontal direction position of the machine tool chief axis center relative to workpiece 1.
Finally, using standard feeler block to knife in T-type centering block top end surface 6, so that it is determined that machine tool chief axis relative to
The short transverse position of workpiece 1.
In this way, machine tool chief axis is determined relative to the accurate location in three directions of workpiece.
