Adopt the cam boring grab of technical solutions of the utility model, comprise base, eccentric disc and electromagnet, base plays a part to support eccentric disc and electromagnet, and eccentric disc plays horizontal location to workpiece, and electromagnet plays vertical direction location to workpiece; Described base left end is provided with baffle plate and support bar, baffle plate and eccentric disc acting in conjunction carry out horizontal location to workpiece, described support bar is provided with magnifying glass, described magnifying glass and support bar are rotationally connected, and magnifying glass energy clear view drill bit is in the cross mark of whether drill bit during Workpiece boring being aimed to required bore position; Described base upper surface is provided with multiple back-up block, back-up block play a part support workpiece, make workpiece and base upper surface unsettled, drill bit can not get on base upper surface when drill workpiece; Described base is provided with pit, and described electromagnet is positioned at pit, the upper surface of described electromagnet and the upper surface flush of back-up block, and when electromagnet holds workpiece, the bottom surface of workpiece contacts with back-up block, makes back-up block support workpiece; Described base upper surface is provided with rotation hole and the cross section of rotation hole is circle, and the bottom of described eccentric disc is provided with the turning cylinder matched with rotation hole, and turning cylinder realizes rotating in rotation hole, and described eccentric disc top is provided with handle, and handle conveniently rotates eccentric disc; Described base right-hand member is provided with locating piece, and described locating piece is provided with tapped through hole, and be provided with rotating screw in described tapped through hole, rotating screw plays the role of positioning to eccentric disc; Described electromagnet is between baffle plate and locating piece, and described eccentric disc is between electromagnet and locating piece, and described back-up block is distributed in around electromagnet, has gap between described eccentric disc and locating piece.
Operation principle of the present utility model and beneficial effect are: when using the utility model, base is fixed on the workbench of drilling machine, again cam is placed on back-up block, electromagnet is energized, after electromagnet energising, cam is held, avoid cam in boring procedure because cam vertical tremor makes broken drill.Turning handle makes eccentric disc hold out against cam, cam is horizontal location under the acting in conjunction of baffle plate and eccentric disc, rotary motion screw, screw is made to hold out against eccentric disc, the angle of adjustment magnifying glass makes the setting-out of bore position needed for cam be marked at clear display in magnifying glass, starts drilling machine adjustment bit location and the mark of the setting-out in drill bit alignment cam is holed to cam.After treating cam boring, rotary motion screw makes rotating screw move to the direction away from eccentric disc, and eccentric disc can freely be rotated, and to electromagnet power-off, is taken off by cam carry out next to operation from the utility model fixture.
Cam in boring procedure because cam adopts electromagnet to position to avoid cam vertical tremor to fracture the accident of drill bit, and avoid the situation that weighing wounded appears in cam face, clearly can observe drill bit drill bit when holing by magnifying glass and whether aim at setting-out mark, avoid the inclined phenomenon in hole.
Further, described base is provided with wire guide, and described wire guide communicates with pit, and the wire on described electromagnet is through wire guide.The wire of electromagnet passes from wire guide, avoid wire from base upper surface through time, install in workpiece fabrication and may not note wire is smashed by foreign object because installing.
Further, described electromagnet upper end is provided with protective cover.The iron filings produced in cam boring procedure are avoided to fall in pit.
Further, back-up block is cylinder.Cylinder does not have wedge angle for cuboid and square, the situation that there will not be cam face to be scraped off in cam fixation procedure, and cylinder processing is simple and convenient, and cylinder only needs clamped one time turning complete, but cuboid or square need multiple clamping milling flat.
