In above-mentioned a kind of axle sleeve internal spline gear-shaping clamp, described cone is fixedly connected with by screw with clamp body, and described pull-rod nut is fixedly connected with by screw with pull bar.
Cone upper end described in above-mentioned a kind of axle sleeve internal spline gear-shaping clamp is provided with dust cover, and dust cover and be held on the contact-making surface of workpiece and be provided with oil sealing.
In above-mentioned a kind of axle sleeve internal spline gear-shaping clamp, the skewed slot of described cone is placed in the top of cone, and the skewback of described chuck is placed in the top of chuck, and cone and chuck are connected by skewed slot and skewback respectively.
The utility model beneficial effect compared to existing technology is: the utility model adopts positioning datum and technological datum unification, use basic major diameter and lower benchmark center hole is located as common reference, high and the strong point of clamp precision and cutting point are substantially large in same cross section inner support rigidity, compact conformation and efficiency are high, and have realized reducing clamping position (large cylindrical) from the distance at gear shaping position, the cutter phenomenon and then guaranteed its crudy of having avoided shaking by the elasticity spacer shell.
The accompanying drawing explanation
Fig. 1 is the cutaway view of a kind of axle sleeve internal spline of the utility model gear-shaping clamp.
Fig. 2 is the cutaway view of A-A direction in Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
A kind of axle sleeve internal spline gear-shaping clamp as shown in Figure 1, comprise clamp body 3, pull bar 2, be provided with the cone 7 of skewed slot and be built in cone 7 and lock the chuck 5 that is held workpiece 11, cone 7 is fixedly connected with clamp body 3, pull bar 2 is fixedly connected with chuck 5, and described chuck 5 lateral walls are provided with the sloping platform matched with skewed slot on cone 7, described chuck 5 and be held on the contact-making surface of workpiece 11 and be provided with elasticity spacer shell 8.
With reference to figure 2, above-mentioned in, in order to guarantee the concentricity of its benchmark, described elasticity spacer shell 8 is by a ring set as the resilient sleeve matrix, the ring set end face is evenly equipped with through hole 13, and radially alternating cuts open through hole and makes ring set have certain elasticity.By elasticity spacer shell 8 stress when shrinking concentrate little, without radial distorted distortion, the drawback of having avoided general elasticity spacer shell 8 axially to cut open.
