Description
Technical field
The utility model relates to a kind of fixture of convenient boring, is specifically related to a kind of fixture for the boring of cylindrical workpiece wall.
Background technology
In machining, usually need cylindrical workpiece to hole on thin-walled, but because the axial dimension of this type of workpiece is compared with large and radial dimension is less, and barrel is thinner easily deforms, is difficult for man-hour clamping it is being added.Clamping force too conference makes workpiece deformation, destroys workpiece; Clamping force is too little, adds man-hour workpiece and is moved, and has a strong impact on crudy.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and dedicated fixture for drilling on a kind of cylindrical workpiece wall providing, it can solve the difficult problem of holing on the barrel of cylindrical workpiece.
The purpose of this utility model is achieved in that
Dedicated fixture for drilling on a kind of cylindrical workpiece wall, it comprises clamp body, and clamp body middle part is provided with through hole, and long axle is installed in through hole, and the top of clamp body is provided with the drill bushing vertical with central shaft.
Above-mentioned long axle comprises the first shaft part, and the first shaft part is connected with the second shaft part, and the second shaft part is connected with the 3rd shaft part, and the 3rd shaft part is connected with the 4th shaft part, and the 4th shaft part is connected with the 5th shaft part;
The second shaft part inserts in the through hole of clamp body, and fixes by nut and clamp body, and the aperture of the 3rd shaft part is greater than the aperture of the second shaft part;
Drill bushing is vertical with the 4th shaft part.
Above-mentioned clamp body is inverted T shape structure, and its bottom is provided with groove.
Above-mentioned one end perpendicular to drill bushing is provided with bar shaped projection, and screw is pressed on bar shaped projection on clamp body.
The utility model has been obtained following technique effect:
Employing said structure, is loaded in the workpiece of needs boring in long axle, and by long axle two ends mounting nuts, can well workpiece be firmly fixed in long axle, then by the drill bit cutter in drill bushing, the fine boring that completes very easily barrel of energy;
Adopt long axle to comprise the first shaft part, the first shaft part is connected with the second shaft part, and the second shaft part is connected with the 3rd shaft part, and the 3rd shaft part is connected with the 4th shaft part, and the 4th shaft part is connected with the 5th shaft part, the second shaft part inserts in the through hole of clamp body, and fix by nut and clamp body, the aperture of the 3rd shaft part is greater than the structure in the aperture of the second shaft part, free end mounting nuts at the first shaft part and the 5th shaft part can well grown Workpiece clamping in axle, the second shaft part very firmly holding in the through hole of clamp body, the 3rd shaft part can be replaced according to the difference of workpiece diameter, thereby can make workpiece closely be fixed on the 3rd shaft part, the 4th shaft part is coupling part, select the long axle with appropriate length the 4th shaft part can meet the demand to long axle length in actual conditions according to the actual conditions of workpiece,
Adopting clamp body is inverted T shape structure, and reeded structure is established in its bottom, and groove can coordinate with the lathe with guide rail, well completes the boring work of workpiece;
Adopt and be provided with bar shaped projection perpendicular to one end of drill bushing, bar shaped projection is pressed on the structure on clamp body by screw, can on the basis that well drill bushing is fixed on to clamp body, facilitate replacement, the maintenance of drill bushing.
