Abstract
The utility model relates to a novel drilling fixture employing rotational positioning. The novel drilling fixture comprises a fixture body, a bottom plate, positioning mandrels, a positioning block and a rotary shaft, wherein the drilling fixture is fixedly arranged on a drilling machine workbench through the bottom plate, the positioning mandrels are symmetrically arranged at the two sides of the positioning block, the fixture body is connected with a drill plate, multiple drill bushings are arranged in the drill plate, the rotary shaft is arranged in the fixture body and the bottom plate, and the fixture body is rotated on the bottom plate by taking the rotary shaft as the circle center. The novel drilling fixture has the advantages of simple structure, use convenience, low production cost and the like. The novel drilling fixture employing rotational positioning enables the fixture body to rotate on the bottom plate by taking the rotary shaft as the circle center and also enables the drill bushings to automatically align to a drill bit in sequence by utilizing a steel ball and a concave pit fixing device arranged at the bottom surface of the fixture body, so that the positioning precision is guaranteed, the labor intensity of operators is reduced, and the working efficiency is greatly improved.
Description
Technical field
The utility model relates to the boring frock clamp of a kind of bench drill, relates in particular to a kind of novel boring grab through positioning of rotating.
Background technology
Traditional when on bench drill, holing; Be earlier workpiece to be contained on the anchor clamps, again first drill bushing of drill bit holed that the manual movement anchor clamps are aimed at drill bit with another drill bushing again; Bore second hole; And the like, the problem that the anchor clamps of this kind structure exist is: uses loaded down with trivial details, increased between working strength of workers, drill bit and the drill bushing that the location is inaccurate, needs correction position repeatedly, greatly reduce operating efficiency.
The utility model content
The utility model is in order to overcome the above problems the novel boring grab through positioning of rotating that a kind of simple in structure, accurate positioning, high efficiency are provided.
The technical scheme of the utility model is: described boring grab comprises clamp body, base plate, location mandril, locating piece and rotating shaft; Described boring grab is fixed on the Drilling machines bench through base plate; Described location mandril is symmetricly set on the locating piece both sides, is connected with bushing plate on the described clamp body, is provided with a plurality of drill bushings in the bushing plate; Described rotating shaft is arranged in clamp body and the base plate, and described clamp body is that rotate on base plate in the center of circle with the rotating shaft.
Described rotating shaft center be a plurality of drill bushings center the center of circle of definite flat circle.
Described base plate is provided with groove, is provided with steel ball, spring and holding screw in the groove, and described steel ball partly protrudes from groove surfaces; Described clamp body bottom surface is provided with the location pit that a plurality of confession steel balls slip into, and described a plurality of pits are coaxial corresponding respectively with a plurality of drill bushings.
The utlity model has advantages such as simple in structure, easy to use, that production cost is low; Through the boring grab of positioning of rotating, be that rotate clamp body in the center of circle on base plate with the rotating shaft, and utilize the pit fixed position of steel ball and clamp body bottom surface; Make drill bushing can aim at drill bit successively automatically; Not only guarantee locating accuracy, reduced operative employee's labour intensity again, improved operating efficiency greatly.
