DETAILED DESCRIPTION

[0017] 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.

[0018] like Figures 1 to 3 As shown, the embodiment of the present application provides a glass lathe, including a frame 1, a main shaft support 2 and a secondary shaft support 4 arranged opposite to each other, a main shaft chuck 3 rotatably connected to the main shaft support 2 through a rotating shaft, and a secondary shaft chuck 5 rotatably connected to the secondary shaft support 4, wherein the main shaft support 2 is fixedly connected to the frame 1, and the secondary shaft support 4 is slidably connected to the frame 1, and the glass lathe also includes a main shaft synchronous wheel 6, a main shaft output wheel 7, a rotation drive assembly and a transmission assembly, wherein the main shaft synchronous wheel 6 and the main shaft output wheel 7 are respectively fixedly connected to the main shaft chuck 3, and specifically, the main shaft synchronous wheel 6 and the main shaft output wheel 7 are respectively fixedly connected to one end of the rotating shaft away from the main shaft chuck 3. The rotation drive assembly is transmission-connected to the main shaft synchronous wheel 6, and the transmission assembly includes a transmission input end, a transmission output end and an electromagnetic clutch synchronous wheel 12, wherein the electromagnetic clutch synchronous wheel 12 is connected to the transmission input end, the main shaft output wheel 7 is transmission-connected to the electromagnetic clutch synchronous wheel 12, and the transmission output end is transmission-connected to the secondary shaft chuck 5. The processing device is also included, which can be a flame spraying device that can move along the axis direction of the main shaft chuck 3 and the secondary shaft chuck 5, and is used to soften the glass workpiece. The existing technology is specifically adopted, and it is not repeated in this embodiment. The electromagnetic clutch synchronous wheel specifically adopts the existing technology, which mainly includes an electromagnetic clutch and a synchronous wheel arranged on the electromagnetic clutch.

[0019] When the above-mentioned glass lathe is working, one end of the glass workpiece is connected to the main shaft chuck 3, and the other end of the glass workpiece is connected to the secondary shaft chuck 5. When a torsion angle appears between the main shaft chuck 3 and the secondary shaft chuck 5, the electromagnetic clutch is disconnected. At this time, the electromagnetic clutch synchronous wheel 12 loses the electromagnetic constraint and can rotate relative to the main shaft synchronous wheel 6, which can greatly reduce the constraint of the drive component on the electromagnetic clutch synchronous wheel 12. Therefore, the glass workpiece close to one end of the secondary shaft chuck 5 can be rotated without loosening the secondary shaft chuck 5 to eliminate the torsion angle. When working, the electromagnetic clutch is energized, and the electromagnetic clutch synchronous wheel 12 and the main shaft synchronous wheel 6 rotate synchronously, thereby driving the glass workpiece to rotate, so that the processing device can process it.

[0020] In the above method, through the setting of the electromagnetic clutch, when it is necessary to adjust the angle between the glass workpiece and the secondary shaft chuck 5, it is only necessary to control the electromagnetic clutch to engage and disengage to adjust the position without releasing the secondary shaft chuck 5, thereby reducing the process of secondary adjustment of the concentricity of the glass workpiece and effectively improving the processing efficiency of the glass workpiece.

[0021] In this embodiment, the rotary drive assembly includes a drive motor 10 fixed on the frame 1, a motor drive wheel 11 fixed on the output shaft of the drive motor 10, and a first transmission belt 8 connected between the motor drive wheel 11 and the spindle synchronous wheel 6. When the drive motor 10 rotates, the rotational driving force is transmitted to the spindle synchronous wheel 6, thereby driving the spindle chuck 3 to rotate, and the transmission input end is selectively driven or not driven to rotate through the electromagnetic clutch, which has the advantages of simple structure and good stability.

[0022] In this embodiment, the transmission assembly also includes a hexagonal synchronization rod 13 rotatably connected to the frame 1, one end of the hexagonal synchronization rod 13 constitutes the transmission input end, and the other end constitutes the transmission output end, the electromagnetic clutch synchronization wheel 12 includes a connecting end and a clutch output end, the connecting end is fixed on the transmission input end, the clutch output end is transmission-connected to the main shaft output wheel 7 through a second transmission belt 9, an output wheel 14 is slidably connected to the transmission output end, and there is no relative rotation between the output wheel 14 and the hexagonal synchronization rod 13, a secondary shaft synchronization wheel 16 is fixedly connected to the secondary shaft chuck 5, and the output wheel 14 and the secondary shaft synchronization wheel 16 are transmission-connected through a third transmission belt 15.

[0023] In this embodiment, a support block 18 extends downward from the countershaft support 4, and one end of the support block 18 away from the countershaft support 4 is connected to the output wheel 14 through a bearing 19. The end of the output wheel 14 is fixedly connected to a connecting portion 141, and a connecting groove is provided on the support block 18. The bearing 19 includes an inner ring and an outer ring. The inner ring of the bearing 19 is interference-fitted with the outer peripheral wall of the connecting portion 141, and the outer ring of the bearing 19 is interference-fitted with the inner peripheral wall of the connecting groove. Through the arrangement of the support block 18 and the bearing 19, the output wheel 14 can be supported by the support block 18 when sliding on the hexagonal synchronization rod 13, which is conducive to improving the sliding stability of the output wheel 14.

[0024] In this embodiment, the main shaft chuck 3 and the secondary shaft chuck 5 are both three-jaw chucks.

[0025] In this embodiment, the secondary shaft support 4 is slidably connected to the frame 1 through the slide rail pair 17. The slide rail pair 17 is provided to make the sliding of the secondary shaft support 4 more stable and smooth, and the sliding of the secondary shaft support 4 can facilitate the adjustment of the spacing between the main shaft chuck 3 and the secondary shaft chuck 5, so as to adapt to glass workpieces of different lengths.

[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
