Abstract
The utility model relates to a machine tool chuck, in particular to a magnetic steel boring center hole chuck, comprising a mandrel, a locking nut screw-threaded with the head of the mandrel and a center installation hole arranged on the tail end of the mandrel and a center hole is arranged in the axial center of the mandrel head, the mandrel head is gripper-shaped comprising a plurality of flap bodies, the center hole is formed by connection of holes with different bore diameters and the bore diameter near the flat body end face is longer than the bore diameter of the inner side hole. The utility model is easy for mounting clip, facilitating processing the magnetic steel boring center hole chuck and essentially solving the technical problem that the common machine tool chuck can not clamp magnetic steel work piece and bring hardness for the boring center hole.
Description
Technical field
The utility model relates to a kind of jig, relates in particular to a kind of magnet steel boring centre bore anchor clamps.
Background technology
Need the magnet steel of boring centre bore cylindrical, cylindrical outer diameter is divided into ascending different which floor, can't clamp this magnet steel workpiece with general lathe boring centre bore anchor clamps, and the processing of boring centre bore brings difficulty on the magnet steel workpiece thereby give.
Summary of the invention
The utility model provides the magnet steel boring centre bore anchor clamps that a kind of magnet steel clamping workpiece is convenient, be convenient to process, and mainly solves general jig and can't clamp the magnet steel workpiece, bring the technical problem of difficulty for the boring centre bore.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises mandrel, the locking nut that is connected with the mandrel head threads, the mandrel afterbody is provided with center mounting hole, the axle center of described mandrel head is provided with centre bore, described mandrel head is the gripper shape of being made up of some lobe bodies, described centre bore is formed by connecting by different hole, several apertures, and the aperture in the hole of close lobe body end face is greater than the aperture in the hole of inboard.The centre bore of mandrel head mates with the appearance and size of the magnet steel workpiece that need clamp.The center mounting hole of mandrel afterbody is installed on the lathe, need clamp workpiece and fill in the centre bore of mandrel head, and then at mandrel head cover upper locking nut and tighten, gripper has just tightly been clamped the magnet steel workpiece, guarantees that the operation of boring centre bore carries out smoothly.
As preferably, be connected with a lobe body inclined-plane between described lobe body end face and the external side of lobe, the screwed hole of described locking nut is provided with a fastening inclined-plane, and described fastening inclined-plane cooperates with described lobe body inclined-plane, and described fastening inclined-plane is close to an end face of described locking nut.Guarantee that further locking nut has firm tightening force to the mandrel head, guarantees firmly clamping the magnet steel workpiece.
As preferably, described centre bore is formed by connecting by different hole, three apertures, and the bottom of described centre bore is coniform.
As preferably, described lobe body has four, and along mandrel head circumference evenly, be symmetrically distributed.Guarantee that the tightening force around the workpiece is even, also be convenient to the making of mandrel.
The beneficial effects of the utility model are: be convenient to clamp the cylindrical magnet steel workpiece that constitutes by which floor various outer diameter, guarantee carrying out smoothly of on this magnet steel workpiece boring centre bore, guarantee machining accuracy.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: the magnet steel boring centre bore anchor clamps of present embodiment as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, comprise mandrel 1, the locking nut 2 that is connected with the mandrel head threads.The mandrel afterbody has a center mounting hole 3, there is a centre bore 4 in the axle center of mandrel head, the mandrel head is the gripper shape of being made up of four lobe bodies 5, four lobe body 5, symmetrical distributions even along mandrel head circumference, be connected with a lobe body inclined-plane 5-3 between the external side 5-2 of lobe body end face 5-1 and lobe, one end of the screwed hole next-door neighbour locking nut 2 of locking nut 2 is provided with a fastening inclined-plane 2-1, and fastening inclined-plane 2-1 cooperates with lobe body inclined-plane 5-3.Centre bore 4 is formed by connecting by different hole, three apertures, and the aperture in the hole of close lobe body end face 5-1 is greater than the aperture in the hole of inboard, and the bottom of centre bore 4 is coniform.The geomery of centre bore is complementary with the magnet steel workpiece appearance and size that needs clamping.
The center mounting hole of mandrel afterbody is fixed on the lathe, put into the magnet steel workpiece that need clamp in the centre bore of mandrel head,, make the lobe body tightly fasten the magnet steel workpiece then at mandrel head cover upper locking nut and tighten, clamping is finished, and just can carry out the boring centre bore on magnet steel and operate.
The utility model convenient mounting and clamping is convenient to the processing of magnet steel boring centre bore, and is guaranteed machining accuracy.
