The hydraulic fluid port hole to be processed stating valve body is axially in plumb position；When described three two and described seven the assembling perforation positioning hole
One coaxial time, the inclined hole to be processed of described valve body is axially in plumb position；When described three position hole three with described seven
When one of assembling perforation is coaxial, the telltale hole to be processed of described valve body is axially in plumb position.
Therefore, only need a frock can realize the location processing of hydraulic fluid port hole, inclined hole and telltale hole, thus avoid anti-
Dismount the trouble of frock again, significantly improve work efficiency, and advantageously ensure that crudy.
Further, described centre bore periphery be shaped be positioned at first quartile hole, upper location, be positioned at first quartile and second as
Limit the hole, middle location of junction, be positioned at the hole, lower location of fourth quadrant.
Further, described base plate two ends are formed respectively with " u "-shaped draw-in groove.
Further, the location end face of described riser fixes the backing plate with hole, corresponding three location, and both sides, other end are divided
It is not connected with reinforcement gusset.
Further, the overhanging end of described horizontal mandrel has the center screw of the hold-down bolt being screwed into band open washer.

Detailed description of the invention
Embodiment one
The valve body multistation processing tool of the present embodiment as shown in Figure 1 and Figure 2, including horizonal base plate 1-1 with by base plate 1-1
The base 1 that the riser 1-2 extended upward is constituted, base plate 1-1 two ends are formed respectively with " u "-shaped draw-in groove 1-3, for frock being disposed
Location when being fixed on lathe table top, riser 1-2 is shaped with the centre bore 1-4 of plug-in mounting cantilever mounted shape horizontal mandrel 2.Horizontal mandrel 2
For adding the central mounting hole C1 being set with steering gear valve body F man-hour, because its external diameter is with steering gear valve body F central mounting hole C1's
Diameter compatible.Centre bore 1-4 periphery is shaped with distribution circle and assembles, with valve body seven, three location that perforation C2 distribution circle is isometrical
Hole be positioned at Fig. 2 first quartile upper location hole 1-5, be positioned at first quartile and the second quadrant junction middle location hole 1-6,
It is positioned at the lower location hole 1-7 of fourth quadrant.The location end face of riser 1-2 fixes the backing plate 6 with hole, corresponding three location, another
End face both sides are connected with reinforcement gusset 5 respectively.The overhanging end of horizontal mandrel 2 has the hold-down bolt 4 being screwed into band open washer 7
Center screw.
When the upper location hole 1-5 in one of hole, three location assemble with seven one of the C2 that bore a hole by plug-in mounting alignment pin 3 at
When coaxial position, seeing Fig. 5, axially vertical plane A in hydraulic fluid port hole to be processed with valve body F is in level, hydraulic fluid port hole is axially located
In plumb position.When hole, three location two lower location hole 1-7 assemble with seven one of the C2 of boring a hole by plug-in mounting alignment pin 3 at
When coaxial position, the inclined hole to be processed seeing Fig. 6, valve body F is axially in plumb position.When fixed in the three of hole, three location
When position one of hole 1-6 and seven assembling perforation are in coaxial position by plug-in mounting alignment pin 3, telltale hole axle to be processed with valve body F
It is in level, telltale hole to vertical plane C and is axially in plumb position.
Add man-hour, carry out by step in detail below:
The first step, by " u "-shaped draw-in groove, after valve body multistation processing tool is fixed on lathe worker platform, valve body
Central mounting hole is inserted on mandrel, make the positioning end of alignment pin stretched out by hole, upper location one of assembling perforation injecting valve body,
Valve body hydraulic fluid port to be processed hole is axially in plumb position, screws the hold-down bolt of mandrel outer end, compresses angular by open washer
The valve body of location；
Second step, lathe make drill bit in place by the coordinate dimension feeding of hydraulic fluid port hole, under be drilled into the processing in hydraulic fluid port hole；
3rd step, unclamp hold-down bolt, make the positioning end of alignment pin be stretched out the assembling perforation injecting valve body by hole, middle location
One of, valve body inclined hole to be processed be axially in plumb position, then screw the hold-down bolt of mandrel outer end, compress by open washer
The valve body of angular location；
4th step, lathe make drill bit in place by inclined hole coordinate dimension feeding, under be drilled into the processing of inclined hole；
5th step, unclamp hold-down bolt, make the positioning end of alignment pin be stretched out the assembling perforation injecting valve body by hole, lower location
One of, valve body telltale hole to be processed is axially in plumb position, then screws the hold-down bolt of mandrel outer end, by open washer pressure
The valve body of tight angular location；
6th step, lathe make drill bit in place by telltale hole coordinate dimension feeding, under be drilled into the processing of telltale hole.
It was verified that after using the frock of the present embodiment, be not only due to only to need frock can while processing oil oral pore,
Inclined hole and telltale hole, thus avoid frock and frequently change the trouble caused, time saving and energy saving, and advantageously ensure that various
Positional precision, thus improve the crudy of steering gear valve body.
Embodiment two
As shown in Figure 8, its basic structure is identical with embodiment one, difference for the valve body multistation processing tool of the present embodiment
Place is that hole, location, three, upper, middle and lower has catch spring step 3-3 away from one end of band guide cone positioning end 3-1, in hole, each location
The ladder shaft-like alignment pin 3 that plug-in mounting matches therewith respectively, and by the magnetic head bolt 3-5 axial limiting of belt washer.Alignment pin 3
Ladder end face and shelves spring step 3-3 between equipped with the spring 3-2 making alignment pin 3 have overhanging trend.So, in the course of processing
When valve body needs angular indexing, unclamp hold-down bolt, simultaneously temporary transient with two without determining of playing the role of positioning with a steel bar
After the pin magnetic head spiral adhesive of position, overcome acting force of the spring to retract the positioning end of this two alignment pin, make remaining alignment pin position
End stretches out reeve valve body and assembles one of perforation accordingly and position, and so without dismounting alignment pin during indexing, operates the most square
Just.
