[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figure 1-4 The worm gear hob clamping device shown includes a hobbing machine output end 1. A ring 2 is detachably provided inside the hobbing machine output end 1. A circular plate 3 is detachably provided on one side of the ring 2. A cylinder 4 is fixedly connected to one side of the circular plate 3. A milling cutter chuck 6 is slidably sleeved at one end of the cylinder 4. A fastening sleeve 5 is provided around the milling cutter chuck 6 to fasten it. The fastening sleeve 5 and the cylinder 4 can be detached. A worm gear hob 7 is inserted into the center of the milling cutter chuck 6. The inner wall of the opening at one end of the fastening sleeve 5 abuts against the corner of the outer wall of the milling cutter chuck 6. A ramp 14 is fixedly connected to the outer side of the cylinder 4. One side of the ramp 14 fits against one end of the milling cutter chuck 6.

[0019] Tightening the fastening sleeve 5 causes the end mill chuck 6 to move along the outer wall of the cylinder 4. When one end of the fastening sleeve 5 touches the ramp 14, one end of the end mill chuck 6 is lifted up, thus fastening the worm gear hob 7 at the center of the end mill chuck 6.

[0020] like Figure 1 and Figure 3 As shown, a circular hole is provided on one side of the output end 1 of the gear hobbing machine, and a tube 15 is fixedly connected to one side of the ring 2. The tube 15 is inserted into the circular hole on one side of the output end 1 of the gear hobbing machine. Two symmetrical fastening bolts 8 are provided on the outer wall of the output end 1 of the gear hobbing machine. The threaded end of the fastening bolt 8 is screwed into the threaded hole on the outer wall of the tube 15. By screwing the threaded end of the fastening bolt 8 into the tube 15, the ring 2 is fixed at the top of the output end 1 of the gear hobbing machine.

[0021] like Figure 2 and Figure 3 As shown, a square groove 16 is provided on one side of the ring 2, and a plug 10 is fixedly connected to one side of the circular plate 3. The size of the plug 10 is smaller than the size of the square groove 16, and an adjustment device for adjusting the position of the plug 10 is provided on the outer wall of the ring 2.

[0022] like Figure 1 and Figure 4 As shown, the adjusting device includes an adjusting bolt 9 that is threadedly connected to the ring 2. Two symmetrical surfaces of the insert block 10 are provided with circular grooves 12. The bottom end of the adjusting bolt 9 abuts against one of the circular grooves 12. A protrusion 18 is fixedly connected inside the square groove 16. One end of the protrusion 18 is inserted into the interior of the other circular groove 12.

[0023] When one of the circular grooves 12 is fitted into the protrusion 18, the insert block 10 will slide in the square groove 16. By turning the adjusting bolt 9, the bottom end of the adjusting bolt 9 will abut against the circular groove 12, which will fix the circular groove 12 fitted into the protrusion 18 and prevent shaking. At the same time, the circular plate 3 and the circular ring 2 are detachable. Therefore, when encountering worm gear hobs 7 of different sizes, the circular plate 3 can be replaced with a cylinder 4 of the corresponding size.

[0024] like Figure 4 As shown, the outer wall of the cylinder 4 is fixedly connected with thread 13, and the inner wall of the fastening sleeve 5 is fixedly connected with thread 2 17 that matches thread 13.

[0025] like Figure 4 As shown, a through hole 11 is provided on one side of the insert block 10. The center of the through hole 11 is on the same axis as the center of the cylinder 4. When the straight shank of the worm gear hob 7 is relatively long, the through hole 11 facilitates the placement of the straight shank of the worm gear hob 7.

[0026] The working principle of this utility model is as follows: First, insert the insert 15 into the output end 1 of the gear hobbing machine. Then, tighten the fastening bolt 8 to fix the ring 2 to the output end 1. After fixing, insert the insert block 10 into the square groove 16. Then, tighten the adjusting bolt 9 to fix the circular plate 3 to the ring 2. Next, place one end of the end mill chuck 6 onto the outer wall of the cylinder 4, and simultaneously insert the worm gear hob 7 into the central hole of the end mill chuck 6. Then, attach the fastening sleeve 5 to the outer wall of the end mill chuck 6, and simultaneously tighten the fastening sleeve 5 to connect the second thread 17 with the first thread 13. At this time, the inner wall of one end of the fastening sleeve 5 presses against the corner of one end of the end mill chuck 6, causing the end mill chuck 6 to move along the outer wall of the cylinder 4 until one end of the end mill chuck 6 reaches the ramp 14. At this time, one end of the end mill chuck 6 tilts, pressing and tightening the worm gear hob 7. Installation is complete, and it is ready for use.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
