Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1-4, the quick-change hobbing clamp tooling comprises a clamping sleeve 1 and a clamping sleeve base 2, wherein the clamping sleeve base 2 is a T-shaped base, a through hole 6 is formed in the center of a vertical portion of the T-shaped base, the clamping sleeve 1 is inserted into the through hole 6, a mounting hole 7 is formed in a transverse portion of the T-shaped base, a pull rod 3 is detachably connected to the bottom of the clamping sleeve 1, an outer conical surface 11 is arranged at the top of the clamping sleeve 1, an inner conical surface is arranged at a hole opening of the through hole 6, which is far away from the transverse portion, the outer conical surface 11 is matched with the inner conical surface 21, the conical angles of the outer conical surface 11 and the inner conical surface 21 are 5-30 degrees, and the hole diameter of the hole opening of the through hole 6, which is close to the transverse portion, is larger than the hole diameter of the through hole 6. In actual use, the taper angles of the outer conical surface and the inner conical surface are both 12 degrees and are used for being matched with each other to clamp the hobbing mandrel.

As shown in fig. 2, a plurality of vertical through grooves 4 are radially formed in the top of the jacket 1, the vertical through grooves 4 are uniformly arranged around the central shaft, and the vertical through grooves 4 penetrate through the outer conical surface 11. During the in-service use, when being used for the pull rod drop-down, press from both sides the shrink of cover top and press from both sides tight gear hobbing dabber.

As shown in fig. 1-3, the upper portion of the jacket 1 is provided with two positioning slots 5, the wall of the through hole 6 is horizontally provided with a positioning hole 8, when in actual use, a positioning bolt is inserted into the positioning hole, and the inner end of the positioning bolt extends into the positioning slot, so that the jacket is prevented from rotating when moving up and down in the jacket base.

As shown in fig. 1-3, the lower part of the jacket 1 is provided with an external thread 12, and the top surface of the jacket is provided with two screw holes 13. During the in-service use, with set screw in the screw, conveniently press from both sides cover and pull rod threaded connection, firm in connection back is got rid of the screw.

As shown in fig. 5 to 6, two ends of the pull rod 3 are respectively provided with an external thread 31 and an internal thread 32, one end surface of the pull rod 3 is provided with a groove 33, and the groove 33 and the internal thread 32 are located at the same end of the pull rod 3. During the in-service use, the internal thread of pull rod is used for connecting the cover that presss from both sides, and the external screw thread is used for connecting the pneumatic cylinder.

The working principle is as follows: as shown in fig. 5, the jacket base is fixedly mounted on the hobbing machine through screws, the pull rod is in threaded connection with the jacket and the hydraulic cylinder of the hobbing machine, the hydraulic switch of the hobbing machine is pressed down, the hydraulic cylinder of the hobbing machine pulls down the jacket through the pull rod, and the jacket cooperates with the jacket base to clamp the hobbing mandrel a to work. When the gear hobbing machine is used for replacing products, a hydraulic switch of the gear hobbing machine is pressed down, the clamping sleeve is loosened through the pull rod, the gear hobbing mandrel is taken out, the gear hobbing mandrel a of another product is replaced, then the gear hobbing mandrel a is clamped, and the gear hobbing machine starts to work.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and that those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
