As the utility model discloses a further setting, the major part end of positioning core axle extend be provided with can with the rotatory joint complex boss of inlay groove, be provided with the fixture block on the lateral wall of boss, the lateral wall of inlay groove is provided with in notch department and is used for and the rotatory joint complex arc wall of fixture block, be provided with the opening that the fixture block of being convenient for got into the arc wall along positioning core axle insertion direction on the mount pad in the one end of arc wall.
By adopting the scheme, the positioning core shaft can form rotary clamping fit with the embedded groove through the fixture block on the boss, so that the positioning core shaft can be fixedly embedded in the embedded groove, the boss only needs to be rotated when the positioning core shaft needs to be used, the fixture block moves to the opening at one end of the arc-shaped groove from the other end of the arc-shaped groove along the arc-shaped groove, and then the fixture block can be separated from the arc-shaped groove along the opening, so that the positioning core shaft can be taken out of the embedded groove for use; after the positioning core shaft is used, the positioning core shaft is inserted into the embedded groove, then the fixture block enters the arc-shaped groove from the opening, the fixture block is moved to the other end of the arc-shaped groove along the arc-shaped groove through the rotating boss to form clamping matching of the fixture block and the arc-shaped groove, and therefore the positioning core shaft can be prevented from being separated from the embedded groove. Simple structure, easy dismounting.
As a further setting of the utility model, the other end that the lateral wall of arc wall is close to the arc wall is provided with and is used for the fixture block to rotate the protruding muscle that can prevent fixture block towards arc wall one end removal when the arc wall other end.
Adopt above-mentioned scheme, can further improve the stability of joint through protruding muscle, prevent that the fixture block from taking place to remove in the arc wall, avoid the fixture block to remove to the opening part, prevent that the positioning core axle from deviating from the inlay groove.
As a further setting of the utility model, the articulated handle that is provided with a dismouting positioning core axle of being convenient for on the boss, the rotation orbit that corresponds the handle on the boss is provided with and is used for the handle to inlay the recess of establishing, recess and handle shape size adaptation.
By adopting the scheme, the positioning core shaft is convenient to disassemble and assemble by arranging the handle on the boss, the handle can be convenient for a user to apply force to rotate the positioning core shaft, and the handle can be embedded in the groove after the handle is used, so that the use of the positioning core shaft cannot be influenced.
As a further arrangement of the utility model, the half cone angle of the truncated cone-shaped positioning mandrel is 2.855 degrees.
By adopting the scheme, the semi-cone angle is 2.855, which is convenient for size measurement, and the taper of the circular truncated cone is 1 because the semi-cone angle is 2.855 degrees: 10, the workpiece is more convenient to process, and the production requirement is met.
The present invention will be further described with reference to the accompanying drawings.
