On, Anchor plate kit is compressed on the top of annular products, and the jig seat and Anchor plate kit are respectively adopted several and arranged in a ring
Row, are provided with drill jig hole and positioning hole in jig seat；The worm and gear lifting machine is as power output source, and force bearing disk passes through spiral shell
Line is connected and installed in the top of worm and gear lifting machine, several connectors is along the circumferential direction provided with the edge of force bearing disk, even
Fitting is connected by hinge axis III with one end of connecting rod, and the other end of connecting rod on hinge axis II and angular plate by having circle
The one end for having slotted hole c on hole a one end connection, angular plate is connected by hinge axis I with the lower end of undercarriage push rod, undercarriage top
The upper end of bar is against on the positioning bottom surface of annular products after passing through the circular hole d of angled seat, is located at the circular hole b of corner then on angular plate
Connection corresponding with the circular hole e in angled seat.
A kind of application method of annular products boring grab, comprises the following steps：
（a）Product orientation：Annular products are placed into jig seat, the positioning hole in jig seat and annular products positioning pair
All positioned, then compressed with Anchor plate kit with latch after neat；
（b）Product drills：According to the drill jig hole of jig seat, annular products are got out into bottom outlet and reamed in place, so with reamer
After unclamp Anchor plate kit；
（c）Product undercarriage：Driving worm and gear lifting machine is moved downward, and angular plate is promoted around own axes by connecting rod
Rotation, so that undercarriage push rod is moved upwards, most annular products are ejected at last.
The present invention has following advantage：When the 1st, using the present invention, be not in because leave for operator's working space it is narrow and small and
The problem of there is inconvenient operation；2nd, tried one's best and be uniformly distributed in arrangement due to undercarriage push rod, therefore, it is possible to greatly meet production
Uniform force during product undercarriage, makes the damage of product extremely small；3rd, manufacturing cost of the present invention is low and can reach higher essence
Degree is required.

Embodiment
A kind of annular products boring grab as shown in Figure 1, including frame assembly 1 and the worm gear installed in frame assembly 1
Worm screw lifting machine 3, force bearing disk 4, connecting rod 5, angular plate 6, Anchor plate kit 7, undercarriage push rod 8, angled seat 9 and jig seat 10, at it
Middle annular products 14 are placed in jig seat 10, and Anchor plate kit 7 is compressed on the top of annular products 14, the jig seat 10 and pressure
Several are respectively adopted and arranged in a ring in board component 7, and drill jig hole 16 and positioning hole 17 are provided with jig seat 10；The worm gear
Worm screw lifting machine 3 is connected through a screw thread the top for being installed on worm and gear lifting machine 3 as power output source, force bearing disk 4, is holding
The edge of power disk 4 is along the circumferential direction provided with several connectors 15, and connector 15 passes through hinge axis III 13 and one end of connecting rod 5
Connection, the other end of connecting rod 5 is connected by hinge axis II 12 with one end with circular hole a on angular plate 6, is had on angular plate 6
The one end for having slotted hole c is connected by hinge axis I 11 with the lower end of undercarriage push rod 8, and the upper end of undercarriage push rod 8 passes through angled seat 9
It is against after circular hole d and the circular hole f of jig seat 10 on the positioning bottom surface of annular products 14, the circular hole b of corner is located on angular plate 6
Then connection corresponding with the circular hole e in angled seat 9.
A kind of application method of annular products boring grab, comprises the following steps：
（a）Product orientation：Annular products 14 are placed into jig seat 10, the positioning hole 17 in jig seat 10 is produced with annular
