[0020] See also Figure 1-3 , the utility model provides a technical solution: a chuck for glass blanking, comprising a main body, a telescopic rotating mechanism and a clamping claw 11;

[0021] The main body includes a circular shell 1 and a movable pressure cover 2. A rotating end connecting sleeve 3 is arranged inside the circular shell 1. A card slot 4 is provided at the corresponding positions of the inner wall of the circular shell 1 and the outer wall of the rotating end connecting sleeve 3. An extension section 5 is provided at the outer end of the rotating end connecting sleeve 3 of the circular shell 1. The extension section 5 of the circular shell 1 cooperates with a first bearing 14. A clamp 15 is also provided at the outer end of the first bearing 14. The smoothness of the overall rotation is ensured by the first bearing 14. The movable pressure cover 2 is movably matched with the circular shell 1. The movable pressure cover 2 is provided with a plurality of axial holes 6. A plurality of bearing mounting seats 16 are provided inside the movable pressure cover 2 and at each axial hole 6. A second bearing 17 is provided in the bearing mounting seat 16. The rotating telescopic rod 8 cooperates with the second bearing 17. When the movable pressure cover 2 is pressed, the second bearing 17 is used to drive the rotating telescopic rod 8 to be pressed down and ensure the smoothness of the rotating telescopic rod 8 when rotating.

[0022] The telescopic rotation mechanism includes a sleeve 7, a rotating telescopic rod 8 and a guide pin 9. The sleeve 7 is provided with a rotating telescopic rod 8. The sleeve 7 is provided between the circular shell 1 and the rotating end connecting sleeve 3, and the sleeve 7 is clamped on both sides at the clamping grooves 4 opened by the circular shell 1 and the rotating end connecting sleeve 3. An oblique guide groove 10 is opened on one side of the sleeve 7. A guide pin 9 is provided on the side of the rotating telescopic rod 8 located at one end inside the sleeve 7. The guide pin 9 is slidably arranged in the oblique guide groove 10 opened by the sleeve 7. The diameter of the matching part of the guide pin 9 and the oblique guide groove 10 is consistent with the width of the oblique guide groove 10 to ensure that the rotating telescopic rod 8 can rotate smoothly and ensure the stability of the rotating telescopic rod 8. There is no gap, and the clamping claw 11 will not loosen. The rotating telescopic rod 8 is away from the sleeve 7. The end passes through the shaft hole 6 corresponding to the movable pressure cover 2;

[0023] There are several clamping jaws 11, and a connecting groove 12 is opened at one end of the clamping jaw 11. The clamping jaw 11 is connected to the corresponding rotating telescopic rod 8 through the connecting groove 12. The clamping jaw 11 is far away from one end of the rotating telescopic rod 8 and close to the center position of the movable pressure cover 2. A groove is opened on the side, and an anti-slip rubber 13 is arranged in the groove.

[0024] Assembly method and principle of use: insert one end of the rotating telescopic rod 8 into the sleeve 7, then connect the guide pin 9 with the screw hole on the side of the rotating telescopic rod 8. At this time, the corresponding position of the guide pin 9 is located in the oblique guide groove 10 of the sleeve 7. Then press the sleeve 7 into the slot 4 between the inner wall of the circular shell 1 and the rotating end connecting sleeve 3 to fix the sleeve 7. Then press the second bearing 17 into the bearing mounting seat 16 of the movable gland 2, and assemble the movable gland 2 with the circular shell 1, and let the rotating telescopic rod 8 pass through the second bearing 17 and the shaft hole 6 of the movable gland 2. Then connect the connecting groove 12 of the clamp 11 with the end of the rotating telescopic rod 8, and tighten it with bolts and nuts. Finally, install the first bearing 14 on the extension section 5 of the circular shell 1 and limit it by the clamp 15 to complete the assembly. When in use, the end of the rotating shaft is inserted into the rotating end connecting sleeve 3 of the circular shell 1, and the circular shell 1 is driven to rotate through the rotating shaft. When the glass tube is unloaded, the glass tube presses the movable gland 2, and the circular shell 1 drives the second bearing 17 to approach the circular shell 1, so that the rotating telescopic rod 8 is pressed down. During the pressing process, the rotating telescopic rod 8 rotates through the cooperation of the guide pin 9 and the inclined guide groove 10, thereby driving the clamping claw 11 to move closer to the center, so as to clamp the glass tube. And the whole can be rotated without affecting the high-temperature burning of the glass tube. When unloading, a raised slope is set on the track, and the slope is located at the connection between the circular shell 1 and the movable gland 2. When the movable gland 2 passes the slope, the movable gland 2 is lifted along the slope, and the rotating telescopic rod 8 moves outward and rotates. At this time, the clamping claw 11 releases the processed ampoule bottle, and the ampoule bottle is unloaded through the unloading guide assembly. The utility model has a reasonable structure. When the bottom-sealed glass tube presses the movable gland 2, the clamping jaws 11 are driven to move closer to each other and clamp the glass tube by rotating the telescopic rod 8, and the overall rotation can be achieved through the first bearing 14. Firstly, for the ampoule bottle mouth fire processing, the heating uniformity is greatly improved, and the clamping of the clamping jaws 11 can be achieved by pressing down the movable gland 2 and then by rotating the telescopic rod 8 and the cooperation of the guide pin 9 and the sleeve 7. No cylinder cooperation is required, which saves costs and has a simpler structure. A groove is also provided on the inner side of the end of the clamping jaw 11, and an anti-skid rubber 13 is arranged in the groove. On the one hand, it has good anti-skid performance, thereby improving the stability of the ampoule bottle, and on the other hand, it reduces the probability of breaking the glass tube.

[0025] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

[0026] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
