At multi-step process, reduces the process time of workpiece and avoid workpiece mismachining tolerance, drop caused by installation site deviates
The low processing cost of workpiece and the machining accuracy for further improving workpiece；By the cooperation of lock-screw and strip hole, make
Mobile eccentric block can firmly install after movement in place, by the cooperation of positioning briquetting and installation step, scroll chuck be made to exist
Can be firmly installed after being rotated in place, to prevent index chuck in process caused by external force workpiece offset and rotation
Turn, further improves the machining accuracy and processing quality of workpiece.In addition, the utility model matching by limiting plate and mounting groove
Position-limiting action can be played to mobile eccentric block by closing, and avoid the problem that mobile eccentric block angle of arrival after translation in place tilts,
Further improve the translation stability of the machining accuracy and mobile eccentric block of workpiece；Outer-hexagonal rotary head can also facilitate worker logical
The degree of regulation that offset lead screw adjusts the shift position of mobile eccentric block and improves mobile eccentric block is crossed, reduces worker to work
The regulating time of part position and the positioning accuracy for improving chuck.So the utility model has high precision machining, processing cost
Low feature.

Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.Bi-directional shift formula index chuck is constituted as shown in Figure 1, including chuck base 1, chuck base 1 is equipped with
Mounting groove 101, mounting groove 101 is interior to offset lead screw 3 through the connection of lead screw mounting bracket 2, and 3 end of offset lead screw is equipped with outer-hexagonal rotary head
301,3 middle part of offset lead screw is connected with mobile eccentric block 5 through feed screw nut 4, and 5 both sides of mobile eccentric block are equipped with strip hole 501, long
Lock-screw 6 is equipped in hole 501, for 6 lower end of lock-screw through being threadedly coupled chuck base 1,5 center of mobile eccentric block is equipped with can
The scroll chuck 7 of rotation, 7 bottom of scroll chuck are equipped with installation step 701, and 701 side of installation step is equipped with indicator 702, peace
It is evenly distributed with multiple positioning briquettings 8 on dress step 701, graduation apparatus 502, mobile eccentric block 5 are equipped between adjacent positioned briquetting 8
Side is equipped with limiting plate 9, and 9 lower end of limiting plate is arranged in mounting groove 101, and 9 outside of limiting plate, which is equipped with, is fixed on 1 side of chuck base
The dial gauge 10 of edge, 10 end of dial gauge pass through the circular hole connection movement eccentric block 5 on limiting plate 9.
The graduation apparatus 502 is distributed in a ring on the mobile eccentric block 5 of 7 surrounding of scroll chuck.
8 outside of the positioning briquetting is through being bolted mobile eccentric block 5.
The operation principle of the utility model：After workpiece is mounted on scroll chuck 7, worker can pass through outer-hexagonal rotary head
301 pivot offset lead screws 3 make mobile eccentric block 5 do translation work on chuck base 1, to enable the axle center of eccentric shaft
