Very little particularity, the outer wall of workpiece is to be local in the spherical of rule, and therefore, the lower surface of lower platen is as clamping face, in clamping
The arc groove being adapted with workpiece outer wall is opened up on face, it is possible to increase the contact area between lower platen and workpiece, and then ensured
The clamping stability of workpiece.
Resilient rubbber cushion is bonded with the inwall of the arc groove.Preferably, being bonded on arc groove inwall
Flexible rubber blanket so that lower platen forms certain buffer portion when pushing, between deep-slotted chip breaker and workpiece, it is to avoid because of push rod
The active force of application is unstable and causes to occur between lower platen and workpiece sharp impacts, reduces the improper consumable quantity of workpiece,
Reduce production cost.
Nut is fixed with the guide rod.Further, on the guide bar provided with nut, and guide rod is used as fastening
, there is larger difficulty in manual rotation in the support member of block and lower platen, and the nut for passing through setting so that related work
Making personnel can be rotated by sheet metal components such as spanners to guide rod, and then reduce working strength of the workpiece in fastening.
The present invention compared with prior art, has the following advantages and advantages：
1st, guide rod and internal thread hole of the present invention, screw rod and screw are that screw thread coordinates, and guide rod passes through universal ball end
It is connected with one end of fastening block, and screw rod is connected by rotating connector with connecting rod, is being ensured while rotating guide rod and spiral shell
On the premise of bar, it is ensured that fastening block two ends ensure the active force being subject on workpiece to the active force relative equilibrium of lower platen
Stablize relatively, i.e., when workpiece base produces larger vibration because of drilling, one-level fastening, fastening block by lower platen to workpiece
With two grades of fastenings of guide rod, connection component and support base formation, it is ensured that the stability of workpiece, the processing essence of workpiece is improved
Degree；
2nd, the lower surface of lower platen of the present invention opens up the arc being adapted with workpiece outer wall as clamping face on clamping face
Groove, it is possible to increase the contact area between lower platen and workpiece, and then ensure the clamping stability of workpiece；
3rd, the nut that the present invention passes through setting so that related staff can be entered by sheet metal components such as spanners to guide rod
Row is rotated, and then reduces working strength of the workpiece in fastening.
