Description
Technical field
The present invention relates to the clamping of a kind of workpiece or cutter, supporting, positioner, be specifically related to a kind of boring clamping device.
Background technology
Drilling machine refers to the lathe mainly using drill bit machining hole on workpiece.Usual bit is main motion, and drill bit moves axially as feed motion.Drilling machine structure is simple, and machining accuracy is relatively low, can holes drilled through, blind hole, changes special tool, can expand, spot-facing, reams or carries out the processing such as tapping.In process, workpiece is motionless, allows cutter move, and by center cutter alignment hole center, and makes cutter rotate (main motion).The feature of drilling machine is that workpiece maintains static, and cutter rotates.
On drilling machine during processing work, usually to first workpiece be fixed on drill jig, then to work pieces process hole, for columnar workpiece, if radial hole will be bored on barrel, encounter some problems, mainly: 1. columnar workpiece is bad fixing; 2. existing drill jig installation and removal workpiece fabrication is more time-consuming.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of can quick despatch, and can the boring clamping device of stably clamping work pieces.
For achieving the above object, technical scheme of the present invention is:
Boring clamping device, comprise support, bushing plate and drill bushing, described bushing plate is connected with support, drill bushing is connected on bushing plate, wherein, also be provided with locating flange dish, screw rod, nut, stage clip and open washer, described locating flange dish is connected with in the middle part of support, ring flange is provided with the lead coordinating inner hole of workpiece, described drill bushing is positioned at lead side and along lead radial arrangement, locating flange dish is provided with axial through hole, described screw rod is arranged in through hole and two ends are stretched out, screw rod one end is connected with described nut, described compression spring sleeve is located on screw rod, one end and nut offset, the end face of the other end and lead offsets, described open washer one end and base hinged, open at one end coordinates screw rod away from one end of nut, described lead radial direction is provided with stop screw, screw rod is provided with vertically and the gathering sill coordinating stop screw to insert.
When adopting technique scheme, when being in non-clamping work pieces state, nut is in unscrews state, and open washer and screw rod are thrown off.When wanting clamping work pieces, now inner hole of workpiece and lead are aligned, then lead is made to insert in workpiece, rotate open washer subsequently, its openend is made to insert on screw rod, now, one end face of open washer and workpiece offsets, fastening nut subsequently, lead radial direction is provided with stop screw, screw rod is provided with vertically and the gathering sill coordinating stop screw to insert, so in rotating nut process, screw rod can not rotate, only can move axially along self, so pull bar moves towards nut side, stage clip is further compressed, open washer is pulled simultaneously, thus by Work-sheet pressing on locating flange dish, now complete clamping, the drill bit of drilling machine is holed to workpiece by drill jig sleeve.Unscrew nut after machining, now, under the restoring force of stage clip, screw rod is movement oppositely, makes open washer unclamp workpiece, rotates open washer, makes openend and screw rod throw off and can take out workpiece.Inner hole of workpiece, when filling workpiece, only need be enclosed within lead by the present invention, rotates open washer and gas openend is coordinated with screw rod, and when dismantling workpiece, after only need unscrewing nut, rotate open washer and gas openend and screw rod are thrown off, so can workpiece loading and unloading more quickly.Screw rod is provided with the lead coordinating inner hole of workpiece, and workpiece both ends of the surface are clamped by open washer, locating flange dish respectively, so clamping is stable.
Further, described nut is provided with the handler radially arranged.So just can increase the moment turning nut, make to turn nut lighter, and need not by the instrument of conversion.
Further, described lead outer surface is provided with keyway.After workpiece hole to be drilled is enclosed within lead, then connected by key, can locate, can prevent again workpiece from rotating.
Further, described locating flange dish is connected by least three bolts with support.Bolted mode is convenient to handling, and ring flange and support can be connected firmly by three bolts.
Accompanying drawing explanation
Fig. 1 is that the present invention holes the schematic diagram of clamping device embodiment.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
As shown in Figure 1, a kind of boring clamping device, comprise support 1, bushing plate 2 and drill bushing, bushing plate 2 is connected with support 1, drill bushing is connected on bushing plate 2, wherein, also be provided with locating flange dish 4, screw rod 7, nut 6, stage clip 5 and open washer 8, locating flange dish 4 is connected with in the middle part of support 1, ring flange is provided with the lead 9 coordinating workpiece 14 endoporus, drill bushing is positioned at lead 9 side and along lead 9 radial arrangement, locating flange dish 4 is provided with axial through hole, screw rod 7 is arranged in through hole and two ends are stretched out, screw rod 7 one end is connected with nut 6, stage clip 5 is set on screw rod 7, one end and nut 6 offset, the end face of the other end and lead 9 offsets, open washer 8 one end and base hinged, open at one end coordinates screw rod 7 away from one end of nut 6, lead 9 radial direction is provided with stop screw 11, screw rod 7 is provided with vertically and the gathering sill 10 coordinating stop screw 11 to insert.
In the present embodiment, nut 6 is provided with the handler 12 radially arranged.So just can be increased the moment turning nut 6 by handler 12, make to turn nut 6 lighter, and need not by the instrument of conversion.
