Lid, the second straight pin, are provided with square feeler block, bearing and side in nail, undersetting, hex nut, bolt, semicircle above bearing
Shape feeler block is connected by the first hexagon socket cap head screw, the first straight pin, and in the middle of clamp body lower surface positioning key is provided with,
Clamp body upper surface is provided with adjustable supports bolt, and clamp body right-hand member is connected with block, and clamp body upper surface is provided with undersetting, lower
Seat is connected with clamp body by the second hexagon socket cap head screw, the second straight pin, is provided with above undersetting in semicircle and is covered,
Undersetting is connected with covering in semicircle by hex nut, bolt, constitutes a kind of hollow gear shaft clamp for machining.
Know-why of the present utility model is：A kind of hollow gear shaft clamp for machining, by square feeler block and the first circle
Pin is engaged, and determines that hollow gear shaft is in correct position in processing relative to cutter.By positioning key and milling machine work
Make the cooperation of platform T-slot, make clamp body that there is correct position relative to workbench.The height of adjustable supports bolt can be adjusted
It is whole, hollow gear shaft is installed convenient.Clamp body right-hand member is connected with block, hollow gear shaft right-hand member is carried out spacing.Plus
Man-hour is placed on hollow gear shaft in two smaller part circular arcs in undersetting, semicircle between lid, with gear on the right side of hollow gear shaft
Block contacts, and lid in undersetting, semicircle is clamped with hex nut, bolt.This fixture is with machined hollow gear shaft two
End is cylindrical to be engaged as positioning datum with lid and block in undersetting, semicircle, is realized to the completely fixed of hollow gear shaft
Position.
The beneficial effects of the utility model are：This clamp structure is simply compact, easy to operate, by undersetting, semicircle
Upper lid and block are worked in coordination, and realize the positioning completely to hollow gear shaft, improve hollow gear shaft machining accuracy.Work as quilt
When the hollow wheel gear shaft diameter of processing changes, only adjustable supports bolt and hex nut need to be adjusted be capable of achieving difference
The positioning of size workpiece is clamped, and without the need for redesigning fixture, reduces production cost.
Description of the drawings
It is presented herein below this utility model is further described in conjunction with the accompanying drawings and embodiments：
