Description
Technical Field
[0001] This utility model relates to the field of spinning machine technology, and in particular to a tailstock for spinning bottle bodies. Background Technology
[0002] In the bottle spinning process, the tailstock is an indispensable key device. Spinning, as a processing method that causes continuous localized plastic deformation of a metal billet under the feed pressure of a spinning wheel during rotation, thereby obtaining a part of the desired shape and size, places extremely high demands on the positioning and support of the billet. The role of the tailstock is to stably support and position the billet during the spinning process, ensuring that the billet is concentric with the spindle of the spinning machine, and guaranteeing the smooth progress of the spinning process.
[0003] Existing bottle spinning tailstocks typically employ a simple rigid connection to fix the blank, using a traditional screw and nut mechanism to achieve axial movement. Their technical principle is primarily based on mechanical transmission, utilizing a motor to rotate the screw, causing the nut to move linearly along the screw, thereby pushing the tailstock to tighten or loosen the blank. Regarding the stability of the tailstock, it relies solely on its own weight and its secure connection to the machine bed to resist the forces exerted during the spinning process.
[0004] During the bottle spinning process, the tailstock sleeve is subjected to complex forces from the spinning process, generating axial and radial forces and causing vibrations. These vibrations cannot be effectively suppressed, leading to positioning deviations of the tailstock. Therefore, a tailstock for bottle spinning is proposed to solve the above problems.

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the tailstock sleeve generates axial and radial forces and causes vibration during operation. The vibration causes the rotating rod to rotate on the connecting rod, pushing the slider to slide along the fixed rod. The compression spring achieves initial buffering. When the tailstock sleeve moves, the pressure is transmitted to the damper, which further buffers the impact force generated by the movement. This solves the problem of positioning deviation caused by the vibration generated when the tailstock sleeve is working, which reduces the processing accuracy of the gas cylinder. The above technical solution improves the stability of the tailstock during operation.
[0023] 2. In this utility model, the water pump is started, and the liquid in the water tank is drawn to the bend pipe through the connecting pipe to cool the tailstock sleeve. Then the liquid carries the heat back to the water tank through the connecting pipe and is cooled by the cooler on the side wall of the water tank, realizing circulation. This solves the problem that the traditional tailstock sleeve has a single structure and cannot perform efficient heat dissipation. The heat dissipation efficiency of the tailstock sleeve is improved through the above technical solution. Attached Figure Description

[0030] 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.
[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a bottle body spinning tailstock, comprising a fixing frame 1, a tailstock sleeve 2 disposed inside the fixing frame 1, connecting frames 3 fixedly connected to both sides of the tailstock sleeve 2, a cooling assembly disposed inside the fixing frame 1, and a buffer assembly disposed between the fixing frame 1 and the connecting frames 3; the buffer assembly includes a sliding frame 4 and a fixing post 12, the sliding frame 4 being fixedly connected to the side wall of the connecting frame 3, the fixing post 12 being fixedly connected to the side wall of the fixing frame 1, the fixing post 12 being slidably assembled with the sliding frame 4, a damper 13 being fixedly installed between the connecting frame 3 and the fixing post 12, the damper 13 being used to buffer the impact force generated when the tailstock sleeve 2 moves, and the buffer assembly also includes a fixing frame 5 and a spring 8. A pair of fixed frames 5 are fixedly connected to the sliding frame 4. A fixed rod 6 is fixedly connected inside the fixed frame 5. A slider 7 is slidably connected to the fixed rod 6. A spring 8 is sleeved on the fixed rod 6. The spring 8 is used to convert the kinetic energy of vibration into elastic potential energy for storage, and to provide initial buffering for the vibration of the tailstock sleeve 2. One end of the spring 8 is fixedly connected to the side wall of the slider 7, and the other end of the spring 8 is fixedly connected to the inside of the fixed frame 5. A rotating rod 11 is provided on both sides of each fixed column 12. A connecting rod 10 is rotatably installed on one end of the rotating rod 11. The other end of the rotating rod 11 is rotatably assembled with the slider 7. The connecting rod 10 is fixedly assembled with the fixed frame 1 through the connecting frame 9. The two rotating rods 11 on the same side are distributed in a V-shape.
[0032] The tailstock sleeve 2 plays a crucial role in supporting and transmitting power during the gas cylinder manufacturing process. During operation, the gas cylinder blank experiences axial and radial forces due to processing stress and its own movement. If these forces are not properly managed, they will affect the stability of the tailstock and the processing accuracy of the gas cylinder. When the tailstock sleeve 2 vibrates, it drives the rotating rod 11 to rotate. The rotating rod 11, connected to the connecting rod 10, rotates, pushing the slider 7 to slide along the fixed rod 6. During this sliding process, the slider 7 compresses the spring 8. The spring 8 has… It possesses elastic potential energy, which can absorb vibration energy when compressed, converting the kinetic energy of vibration into elastic potential energy for storage. This provides initial buffering for the vibration of the tail sleeve 2. Simultaneously, when the tail sleeve 2 moves, the pressure it generates is transmitted to the damper 13. The damper 13, through its internal damping medium and structure, converts the kinetic energy of the tail sleeve 2 into heat energy and other forms of energy for dissipation, thereby buffering the impact force generated when the tail sleeve 2 moves, ensuring the stability of the tail sleeve during operation, and providing stable support for the precise processing of the gas cylinder.
[0033] Reference Figure 1 , Figure 2 and Figure 4The cooling assembly includes a water tank 14 and a water pump 16. The water tank 14 is fixedly installed on the bottom inner side of the mounting bracket 1. A cooler 15 is fixedly connected to the side wall of the water tank 14. The cooler 15 is used to cool the liquid in the water tank 14 that has absorbed heat. Both sides of the tailstock sleeve 2 are fixedly installed with bent pipes 18. The top of the water tank 14 is connected to the input end of the water pump 16. The output end of the water pump 16 is connected to the bent pipe 18 through the connecting pipe 17. The bent pipe 18 is connected to the water tank 14 through the return water pipe. The bent pipe 18 is located in the connecting frame 3 and is continuously distributed in an S-shape. A fixing block 19 is fixedly connected to the side wall of the bent pipe 18. The fixing block 19 is fixedly connected to the side wall of the tailstock sleeve 2. The damper 13 is located in the sliding frame 4.
[0034] During operation, the tailstock sleeve 2 experiences pressure and heat due to friction with the gas cylinder blank and energy transfer during processing. If heat accumulates continuously, it can alter the material properties of the tailstock sleeve 2, affecting its precision and service life. The water pump 16 provides power to extract liquid from the water tank 14 and transports the coolant from the tank 14 to the bent pipe 18 via the connecting pipe 17. The coolant flows within the bent pipe 18, exchanging heat with the tailstock sleeve 2 and absorbing heat from its interior, thus cooling the interior of the tailstock sleeve 2. The cooling process ensures that the tailstock sleeve 2 operates within a suitable temperature range, maintaining its accuracy and performance. The cooled liquid carries the heat from the tailstock sleeve 2 and returns to the interior of the water tank 14 through the connecting pipe 17. The cooler 15 is installed on the side wall of the water tank 14. Its function is to cool the liquid in the water tank 14 that has absorbed heat, reducing the temperature of the liquid to a suitable range for reuse. Through this cycle, continuous and effective cooling of the tailstock sleeve 2 is achieved, ensuring the stability and processing accuracy of the gas cylinder manufacturing process.
[0035] Working principle: When the tailstock sleeve 2 is working, it will generate a certain axial and radial force. When the tailstock sleeve 2 vibrates, it causes the rotating rod 11 to rotate on the side wall of the connecting rod 10. At the same time, the rotation of the rotating rod 11 pushes the slider 7 to slide on the side wall of the fixed rod 6 and compresses the spring 8 to provide initial buffering. Meanwhile, the pressure of the tailstock sleeve 2 when it moves is transmitted to the damper 13, thereby buffering the impact force generated when the tailstock sleeve 2 moves.
[0036] When the tailstock sleeve 2 is working, it will be subjected to a certain pressure and heat. The water pump 16 is started to draw out the liquid inside the water tank 14 through the connecting pipe 17 and deliver it to the inside of the bend pipe 18 to cool the inside of the tailstock sleeve 2. The cooled liquid returns to the inside of the water tank 14 through the connecting pipe 17 and takes away the heat inside the tailstock sleeve 2. The cooler 15 on the side wall of the water tank 14 cools the liquid inside, thus achieving circulation.
[0037] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
