(3) beneficial effect
The utility model proposes a kind of tooling to workpiece rat holing have compared with prior art with following
Beneficial effect:
(1) it is provided with the inclined through-hole of installation workpiece on vertical plate ontology, workpiece is fixed in through-hole, so that workpiece
Favour drill bit, then the vertical core by being arranged on the upside of through-hole；By the change to work piece holder, drill bit is drilled out to workpiece
Inclined hole.
(2) in through-hole limiting slot design, workpiece can be limited.Limiting slot is arranged to V-type or relative to workpiece
It is lesser arc-shaped, so that there are two contact points between limiting slot and workpiece, workpiece is stuck；Workpiece can be prevented in limiting slot
Interior rotation further increases the fixed effect of limiting slot.
(3) workpiece is installed convenient for staff and is taken out in the lateral opening design in through-hole two sides.
(4) it to the restriction of vertical core position and angle, and is used for being oriented to drill bit, can drill bit be gone out to work pieces process
Hole it is more fine.And the setting of through-hole inner washer, vertical plate ontology can be protected, is caused after avoiding drill bit from hurting vertical plate ontology vertical
The damage of plate ontology.
(5) washer is made of Cr12 alloy tool steel, so that washer has stronger wearability and heat resistance；Increase
The service life of washer.The time of replacement washer is saved, and avoids replacement washer and causes unnecessary trouble, is increased
Production efficiency is added.
(6) threaded hole is arranged to bilayer step hole, installation and vertical plate and the fixing piece of fastener can be facilitated
Between stability.
