Abstract
The utility model relates to a drill jig. The drill jig is simple in structure and workpieces are convenient to clamp. The drill jig comprises a base. An installing hole is formed in one side wall of the base in a concave mode. A supporting rod is horizontally fixedly arranged at the position, located in the direction of the axis in the installing hole, of the base. An end face check ring which abuts against the end face of a workpiece is sleeved with the installing hole. A supporting ring is sleeved with the installing hole and attached to the end face check ring, a shaft head of the workpiece is sleeved with the supporting ring, and the supporting ring stretches out of the installing hole and stretches in a protruding mode in the radial direction to form a flange which is attached to the end face of the installing hole. A vertical column is fixedly arranged at the position, close to the flange, of the base. The top end of the base is fixedly connected with a drill bushing installing plate. A drill bushing is arranged on the drill bushing installing plate. The head of the supporting rod is in screw joint with a nut. A gasket is sleeved with the nut. By the arrangement of the end face check ring, the supporting rod, the nut and the gasket, axial motion of the workpiece and the rotating freedom degree of the workpiece are limited; through the supporting ring and the vertical column, the radial freedom degree of the workpiece is limited, and positioning accuracy of a hole in the drilling process is effectively guaranteed.
Description
Technical field
The utility model relates to a kind of drill jig, relates in particular to a kind of upright drill in order to the drill jig to Workpiece boring.
Background technology
In prior art, while workpiece being carried out to Drilling operation on upright drill, for the comparatively special workpiece of some shapes, be often difficult to fix, simultaneously the positioning precision in hole is also difficult to guarantee during Drilling operation.
Utility model content
The purpose of this utility model is to overcome the problem of above-mentioned prior art, and a kind of drill jig is provided, and it is simple in structure, and clamping workpiece is convenient, the positioning precision in hole in the time of effectively guaranteeing Drilling operation simultaneously.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of drill jig, comprise base, one of them sidewall of described base is concaved with installing hole, the axis direction level that described base is positioned at described installing hole is installed with support bar, in described installing hole, be arranged with the end face back-up ring connecting with workpiece end face, described in described installing hole inner close fitting, end face shield ring sleeve is provided with the bracing ring of suit workpiece spindle nose, described bracing ring extends described installing hole and radial projection forms the flange fitting with the end face of described installing hole, on described base, near described flange, be installed with column, the affixed drill bushing installing plate in top of described base, described drill bushing installing plate is provided with drill bushing, the head of described support bar is bolted with nut, the inner side of described nut is arranged with packing ring.
Further, described drill bushing is microscler Quick-change drill bush.
Further, described drill bushing is fixedly mounted on described drill bushing installing plate by housing screw.
Drill jig described in the utility model, it is simple in structure, clamping workpiece is convenient, comprise base, one of them sidewall of base is concaved with installing hole, the axis direction level that base is positioned at installing hole is installed with support bar, in installing hole, be arranged with the end face back-up ring connecting with workpiece end face, installing hole inner close fitting end face shield ring sleeve is provided with the bracing ring of suit workpiece spindle nose, bracing ring extends installing hole and radial projection forms the flange fitting with the end face of installing hole, on base, near flange, be installed with column, the affixed drill bushing installing plate in top of base, drill bushing installing plate is provided with drill bushing, the head of support bar is bolted with nut, the inner side of nut is arranged with packing ring.By the setting of end face back-up ring, support bar, nut and packing ring, the free degree that restriction workpiece moves axially and rotates, by bracing ring and column, the radially free degree of restriction workpiece, thereby the positioning precision in hole while effectively having guaranteed Drilling operation.
