The working principle of the utility model is:
The utility model relates to a kind of high reliability batch machining precision jig, is first installed before processing, when beginning, bolt 16
It is not completely screwed into thread bush 17, by cylindrical work pieces 23 directly through bolt 16 and 17 sets of thread bush on jig axis 19, so that
The left side of 23 right side joint tool column 12 of cylindrical work pieces, then adapter sleeve 18 is set to by the U-shaped stepped groove 181 of its own
On thread bush 17 and bolt 16, bolt 16 is turned, so that the bolt head of bolt 16 compresses the left side of adapter sleeve 18, and then is fastened
Set 18 compresses cylindrical work pieces 23；Similarly, with the above process on the contrary, from thread bush 17 reversed turn bolt 16, can unclamp and take
Lower adapter sleeve 18, and remove cylindrical work pieces 23；Since the left side of ladder set 14 is bonded with the right side of jig column 12, and turning
It is secured in a press under the action of axis 3, threaded rod 7, washer 8, the first nut 5 and the second nut 6, ladder set 4 can pass through bearing
10 rotations so jig column can also cover 4 rotations with ladder, therefore rotate jig column 12 and make the second positioning handle 21 and locating rod 20
It contradicts, completes circumferentially positioned, be aligned the second drilling 192 with guiding sleeve 13 vertically, drill bit can be at this time
Under the guiding of guiding sleeve 13, the upper wall to cylindrical work pieces 23 is bored vertically, and then drill bit 22 drills through the upper wall of cylindrical work pieces 23 simultaneously
The lower wall to cylindrical work pieces 23 is bored through the second drilling 192, finally drills entire cylindrical work pieces 23；Then drill bit 22 lifts, and turns
Dynamic jig column 12 makes that the first positioning handle 11 is allowed to contradict with locating rod 20, complete again it is circumferentially positioned so that the first drilling 191 is perpendicular
Directly it is aligned with guiding sleeve 13, drill bit can bore the upper wall to cylindrical work pieces 23 under the guiding of guiding sleeve 13 vertically at this time,
Then entire cylindrical work pieces 23 is drilled after the first drilling 191, is directed to sleeve 13 when boring since drill bit 22 is lower and guides, prevents
Polarization bounce when only drill bit punches, processing precise is good, while first drilling 191 and the second drilling 192 are mutually perpendicular to, institute
It is also to be mutually perpendicular in 90 degree with the hole drilled out on cylindrical work pieces 23, processing precise is convenient and practical；Drill bit 22 is lifted later,
It turns 16 pine of bolt and clamps lower cylindrical work pieces 23, then prepare to process next.
