Abstract
A kind of convertible boring grab, comprise fixture mount, it is characterized in that abrasion drill template one end is hinged on the side in fixture mount, the abrasion drill template other end arranges locking notch, opposite side in fixture mount arranges datum level locating piece, this side is hinged tie down screw simultaneously, and tie down screw top can penetrate in the locking notch of abrasion drill template, and tie down screw upper end connects locking nut; Below the middle part of abrasion drill template, be fixedly connected with Workpiece fixing screw rod, the lower end of Workpiece fixing screw rod installs packing washer, and connects workpiece locking nut; Below the middle part of abrasion drill template, be fixedly connected with positioning sleeve simultaneously, abrasion drill template arranges uniform drill bushing; In fixture mount, plug-in mounting corner of workpiece is to oriented side pin.Convertible structure of the present utility model can realize the clamping of workpiece one-time positioning, reduces resetting, improves positioning precision, reduces labour intensity, when shortening loader, easy and simple to handle.
Description
Technical field
The utility model belongs to a kind of clamping tool for machine work, particularly a kind of convertible boring grab, for four holes of radial drilling machine processing automobile differential carrier.
Background technology
When utilizing four hole of radial drilling machine processing automobile differential carrier at present, the parts of processing be carried out fixture clamping, first workpiece is fixed on clamp body base plate, then bushing plate is fixed on workpiece, together be clamped in again on clamp body with workpiece.Clamp behind twice location, therefore positioning precision reduces, and labour intensity is large, and iron filings are deposited on clamp body is inconvenient to clear up.
Summary of the invention
The purpose of this utility model is to overcome existing issue, realizes one-time positioning, improves positioning precision, easy and simple to handle, reduces labour intensity.
The utility model solves the technical scheme that its technical problem adopts: comprise fixture mount, it is characterized in that: abrasion drill template one end is hinged on the side in fixture mount, the abrasion drill template other end arranges locking notch, opposite side in fixture mount arranges datum level locating piece, this side is hinged tie down screw simultaneously, tie down screw top can penetrate in the locking notch of abrasion drill template, and tie down screw upper end connects locking nut; Below the middle part of abrasion drill template, be fixedly connected with Workpiece fixing screw rod, the lower end of Workpiece fixing screw rod installs packing washer, and connects workpiece locking nut; Below the middle part of abrasion drill template, be fixedly connected with positioning sleeve simultaneously, abrasion drill template arranges uniform drill bushing; In fixture mount, plug-in mounting corner of workpiece is to oriented side pin.
The beneficial effects of the utility model are: convertible structure can realize the clamping of workpiece one-time positioning, reduces resetting, improves positioning precision, reduces labour intensity, when shortening loader, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the top view of Fig. 1.
Component serial number in figure: positioning sleeve 1, drill bushing 2, abrasion drill template 3, revolution pivot pin 4, Workpiece fixing screw rod 5, hold-down nut 6, bushing plate tie down screw 7, bushing plate locking nut 8, datum level locating piece 9, bearing pin 10, packing washer 11, workpiece locking nut 12, fixture mount 13, angle oriented side pin 14, workpiece 15.
Detailed description of the invention
See Fig. 1-3, concrete structure is as follows: abrasion drill template 3 one end is hinged on the side in fixture mount 13 by revolution pivot pin 4, abrasion drill template 3 other end arranges locking notch, opposite side in fixture mount 13 arranges datum level locating piece 9, this side is simultaneously by the hinged tie down screw 7 of bearing pin 10, tie down screw 7 top can penetrate in the locking notch of abrasion drill template 3, and tie down screw 7 upper end connects locking nut 8; Be fixedly connected with Workpiece fixing screw rod 5 at the middle part of abrasion drill template 3 below by hold-down nut 6, the lower end of Workpiece fixing screw rod 5 installs packing washer 11, and connects workpiece locking nut 12; Below the middle part of abrasion drill template, be fixedly connected with positioning sleeve 1 simultaneously, abrasion drill template 3 arranges four uniform drill bushings 2; In fixture mount 13, plug-in mounting corner of workpiece is to oriented side pin 14.
Operation principle: first unclamp bushing plate locking nut 8, open abrasion drill template 3, the footpath, location of workpiece 15 is put into the positioning sleeve 1 of abrasion drill template 3, angle oriented side pin 14 inserts positioning workpieces in the side locating hole of workpiece 15, again packing washer 11 is put into workpiece seam footpath, tighten workpiece locking nut 12 clamping work pieces.Overturn abrasion drill template 3 centered by bearing pin 4 be leveled on datum level locating piece 9 to turn round, rotary drilling template lock jack panel 8 locks bushing plate, and start processing work, drill bit is holed on workpiece by drill bushing 2.After machining, unclamp bushing plate locking nut 8, open abrasion drill template 3, unclamp workpiece locking nut 12, take off packing washer 11, unload workpiece 15, wait for lower task.
