The specific embodiment
Below in conjunction with Figure of description and embodiment, the clamping device of needle shaft class part of the present invention is elaborated:
As shown in Fig. 1 ~ 4, a kind of clamping device of needle shaft class part, comprise column type positioning body 1, six side's locating holes 2 and pressure pad hole 3 in forming in described positioning body 1, interior six side's locating holes 2 and pressure pad hole 3 communicate, on positioning body 1 outer wall, the position in corresponding pressure pad hole 3 forms screwed hole 4, pressure pad 5 and adjustment pressure pad 6 are installed in pressure pad hole 3, pressure pad 5 is installed on the side near interior six side's locating holes 2, in adjustment pressure pad 6, be formed centrally different diameter hole, adjust bolt 7 and screwed hole 4 threaded engagement, and one end is stretched in the different diameter hole of adjusting pressure pad 6 and is matched with the adjusting nut 8 that is placed in different diameter hole, it is fixing with adjustment bolt 7 that adjusting nut 8 will be adjusted pressure pad 6.
The geomery of described pressure pad 5 and adjustment pressure pad 6 matches with pressure pad hole 3.
Described pressure pad 5 and adjustment pressure pad 6 adhere to.
Using method of the present invention:
A plurality of workpiece 9 are put into six side's locating holes 2 perpendicular to positioning body 1 end face, turn and adjust bolt 7, drive pressure pad 5, adjustment pressure pad 6 to move forward simultaneously workpiece 9 is compressed.
The present invention puts into six side's locating holes 2 by a plurality of workpiece 9 and clamps, six workpiece 9 that each workpiece 9 is adjacent with other contact, like this as long as interior six side's locating holes 2 are compressed near pressure pad hole 3 workpiece 9 on one side, all workpiece 9 in six side's locating holes 2 can not drop out, to the end face of workpiece 9 is processed.
