DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 The utility model provides a technical solution: a high-speed gear hobbing clamping device, including a base 1, a clamping table 2, a fixed bracket 3, a movable sleeve 4, a fixed cylinder 5, a spring 6, a movable rod 7, a fixed frame 8, a connecting mechanism 9, a movable frame 10, a support block 11, an auxiliary rod 12, a connecting cap 13, an auxiliary plate 14, a clamping plate 15, a connecting column 16, a horizontal plate 17 and a fixing bolt 18.

[0031] When using the high-speed gear hobbing clamping device, Figure 1 , Figure 2 and Figure 4 As shown, the upper end of the base 1 is fixedly connected with a clamping table 2. After the processed gear hobbing is transferred to the upper end of the clamping table 2, the connecting column 16 is first pulled downward, and the connecting column 16 slides with the upper end of the fixed bracket 3. The connecting column 16 drives the horizontal plate 17 to move downward, so that the horizontal plate 17 and the upper end of the gear hobbing are kept in close contact, thereby being able to maintain the position of the gear hobbing to prevent the gear hobbing from being skewed, and then the fixing bolt 18 is rotated. The fixing bolt 18 and the fixed bracket 3 as well as the fixing bolt 18 and the connecting column 16 are all threadedly connected. The connecting column 16 and the fixed bracket 3 can be limited by the fixing bolt 18. Then, according to the size of the gear hobbing, the movable rod 7 is pulled, and the movable rod 7 slides with the fixed cylinder 5. The movable rod 7 squeezes the spring 6, so that the spring 6 undergoes elastic deformation. The movable rod 7 drives the fixed frame 8 to move outside the fixed bracket 3. At this time, the middle part of the fixed frame 8 is pulled out from the fixing hole at the corresponding position on the side of the fixed bracket 3, thereby releasing the limit between the movable sleeve 4 and the fixed bracket 3.

[0032] Then, by pulling the movable sleeve 4 up and down as required, the movable sleeve 4 slides with the fixed bracket 3, so as to facilitate the adjustment of the height of the clamping plate 15. When the height is adjusted to a suitable level, the movable rod 7 is directly released. At this time, the spring 6 restores its elastic deformation, driving the movable rod 7 to slide with the fixed tube 5, so that the movable rod 7 drives the fixed frame 8 to engage in the fixing hole at the corresponding position of the side of the fixed bracket 3, thereby facilitating the limit between the movable sleeve 4 and the fixed bracket 3;

[0033] After the limit is completed, Figure 2 , Figure 3 and Figure 5As shown, the connecting mechanism 9 includes a movable frame 10 sleeved on the outer side of the upper end of the movable sleeve 4, a support block 11 fixedly connected to the front and rear sides of the upper end of the movable sleeve 4, an auxiliary rod 12 fixedly connected to the outer side surface of the upper end of the movable sleeve 4, a connecting cap 13 for adjustment and an auxiliary plate 14 for connection. By rotating the connecting cap 13 threadedly connected to the outer surface of the auxiliary rod 12, the connecting cap 13 and the auxiliary plate 14 rotate, so that the auxiliary plate 14 pushes the movable frame 10 to slide between the support block 11. At this time, the movable frame 10 drives the clamping plate 15 to telescopically move, so that the clamping plate 15 stably clamps and fixes the rolling gear, and the overall stability is relatively high.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
