[0019] Compared with the prior art, for this mechanical processing hobbing tooling, through the hob body, expansion sleeve, oil cylinder, variable-diameter pull rod, upper pull rod, bolt and cone disk, when it is necessary to clamp and fix the hob body, first sleeve the hob body on the outer surface of the expansion sleeve, then the oil cylinder works to drive the variable-diameter pull rod to have a downward trend, further driving the upper pull rod and the bolt to have a downward trend, and then the bolt applies a downward force to the expansion sleeve. Due to the presence of the cone disk, the expansion sleeve will deform, and then apply an outward force to the hob body from the inner surface of the hob body, so as to clamp the hob body from the inside, and then the hob body can be processed. Compared with the existing hobbing tooling, when processing tapered hole products, a straight hole needs to be left in the tapered hole for clamping. After the process of hole positioning is completed, the straight hole is turned into a tapered hole.

The limit sleeve 20 is located above the bolt 19. When it is necessary to clamp and fix the hobbing body 2, first, the hobbing body 2 is sleeved on the outer surface of the expansion sleeve 1. Then, the oil cylinder 15 works to drive the variable diameter pull rod 6 to have a downward trend, and then drives the upper pull rod 3 and the bolt 19 to have a downward trend. Then, the bolt 19 applies a downward force to the expansion sleeve 1. Due to the existence of the taper disk 13, the expansion sleeve 1 will deform, and then apply an outward force to the hobbing body 2 from the inner surface of the hobbing body 2, so as to clamp the hobbing body 2 from the inside, and then the hobbing body 2 can be processed. A positioning disk 4 is movably installed on the outer surface of the upper pull rod 3, a taper disk 13 is fixedly connected to the upper surface of the positioning disk 4, an expansion sleeve 1 is sleeved on the outer surface of the taper disk 13, and a hobbing body 2 is sleeved on the outer surface of the expansion sleeve 1.
[0027] The receiving plate 16 has a limiting groove 17 opened on its inner surface. The outer surface of the variable-diameter pull rod 6 is threadedly connected with a limiting screw 9. The limiting screw 9 is located inside the limiting groove 17. The limiting screw 9 can only move in the limiting groove 17, thereby restricting the movement range of the variable-diameter pull rod 6. A groove is opened on the outer surface of the receiving plate 16, and the inner surface of the groove is threadedly connected with a fourth screw 12. The fourth screw 12 is screwed on after the expanding sleeve 1 clamps the hobbing body 2, and restricts the movement of the upper pull rod 3 by pressing the upper pull rod 3, so that the upper pull rod 3 will not move further. A hobbing support 18 is arranged on the upper surface of the receiving plate 16. The hobbing support 18 can support the hobbing body 2. The upper surface of the hobbing support 18 is threadedly connected with a fifth screw 14. The receiving plate 16 and the hobbing support 18 are connected by the fifth screw 14.

A threaded groove is opened on the upper surface of the multi-purpose conversion plate 5, and the inner surface of the threaded groove is threadedly connected with a third screw 11. The third screw 11 is used to fixedly install the multi-purpose conversion plate 5 on a certain platform or base to fix the whole device.
[0029] Working principle: When it is necessary to clamp and fix the hobbing body 2, first sleeve the hobbing body 2 on the outer surface of the expanding sleeve 1. Then the oil cylinder 15 works to drive the variable-diameter pull rod 6 to have a downward trend, and then drives the upper pull rod 3 and the bolt 19 to have a downward trend. Then the bolt 19 applies a downward force to the expanding sleeve 1. Due to the presence of the tapered disc 13, the expanding sleeve 1 will deform, and then apply an outward force to the hobbing body 2 from the inner surface of the hobbing body 2, thereby clamping the hobbing body 2 from the inside, and then the hobbing body 2 can be processed.
