Description

Technical Field

[0001] This utility model belongs to the field of beer barrel welding technology, and relates to a chuck for an automatic beer barrel welding machine. Background Technology

[0002] Beer barrels are containers used for storing and transporting beer. They are also an important part of beer history, culture, and craftsmanship, and play a role in secondary fermentation, carbonation, and maturation. They are widely used in commercial bars, breweries, and banquets. With the development of the times, the material of beer barrels has evolved from ancient oak containers to modern precision stainless steel containers.

[0003] The following technical problems were found in the existing technology: During the welding process of beer barrels, due to the thin walls of the barrels, high clamping precision and stability are required. If the beer barrels are not properly aligned, the welding effect will be poor, which will increase the possibility of gas leakage and contamination by external substances during beer storage, causing losses to the manufacturer. Utility Model Content

[0004] The technical problem this invention aims to solve is that during the welding process of beer barrels, due to their thin walls, high clamping precision and stability are required. If the beer barrels are not properly aligned, the welding effect will be poor, which will increase the possibility of gas leakage and contamination by external substances during beer storage, causing losses to the manufacturer.

[0005] The present invention describes a chuck for an automatic beer barrel welding machine, comprising a cylinder body, wherein a guide cylinder is fixedly connected to the middle of the inner side of the cylinder body.

[0006] A centering clamping assembly is located on the outer side of the cylinder body. The centering clamping assembly includes a reset mechanism and an adjustment mechanism, which work together. The centering clamping assembly includes a gas distribution plate, a piston body, a sealing ring, a chuck body, a pneumatic telescopic sleeve, and a wedge sleeve. The gas distribution plate is fixedly connected to the outer side of the cylinder body. The piston body is fixedly connected to the middle of the inner side of the cylinder body. The piston body is located outside the guide cylinder. The chuck body is fixedly connected to the outer side of the cylinder body. A pneumatic telescopic sleeve is fixedly connected to the output end of the piston body. The pneumatic telescopic sleeve slides outside the guide cylinder. A wedge sleeve is fixedly connected to the end of the pneumatic telescopic sleeve away from the piston body.

[0007] The adjustment mechanism includes a sliding groove, a base claw, a mating inclined plate, a clamping claw, and a circular retaining claw. Multiple sets of sliding grooves are opened on the inner side of the chuck body. The base claw is slidably connected inside the sliding groove. A mating inclined plate is opened on one side of the bottom of the base claw. The mating inclined plate is used in conjunction with the wedge core sleeve. A clamping claw is provided on the outer side of the base claw. A circular retaining claw is provided at the end of the clamping claw away from the base claw. A sealing ring is fixedly connected to one side of the cylinder body.

[0008] The reset mechanism includes a reset groove, a limiting post, a reset spring, and a screw. The chuck body has a reset groove near the sliding groove. The limiting post is fixedly connected inside the reset groove. A base claw is slidably connected to the outside of the limiting post. The reset spring is installed on the outside of the limiting post. A screw is threaded to the top of the outside of the reset groove. The base claw is located at the bottom of the reset spring.

[0009] A disassembly module is provided at the connection between the circular claw and the clamping claw.

[0010] A dust cover is fixed to one end of the outer side of the guide cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By using the adjustment mechanism and the reset mechanism in combination, when clamping beer barrels of different specifications, different strength reset springs are selected to cooperate with each other, providing a more stable and safer clamping of the beer barrels. At the same time, the wedge core sleeve and the matching inclined plate adopt a wedge structure, which makes the chuck clamping accuracy higher. The use of a circular full-enclosure jaw makes the clamping of beer barrels more reliable and stable. After clamping two sets of beer barrels, they are aligned, and then the chuck body is driven to rotate synchronously to complete the welding operation. The high precision and stability of the clamping of beer barrels reduces the risk of poor airtightness due to beer barrel displacement during the welding process, further increasing the practicality and reliability of the device.

[0012] By using the disassembly module and dust cover, the clamping claw and the ring claw are connected through the disassembly module, which facilitates the replacement of the specifications and models of the ring claw to adapt it to beer kegs of different diameters. The dust cover prevents dust from entering the inside of the keg, further reducing the risk of external dust entering the inside of the keg and reducing the risk of shortening the service life of the internal components of the keg.

[0022] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] Example 1

[0025] like Figure 1 - Figure 5 As shown, a chuck for an automatic beer barrel welding machine includes a cylinder 1, and a guide cylinder 2 is fixedly connected to the middle of the inner side of the cylinder 1.

[0026] A centering clamping assembly is located on the outer side of the cylinder body 1. The assembly includes a reset mechanism and an adjustment mechanism that work together. The assembly comprises a distribution plate 3, a piston body 4, a sealing ring 5, a chuck body 6, a pneumatic telescopic sleeve 7, and a wedge sleeve 11. The distribution plate 3 is fixedly connected to the outer side of the cylinder body 1. The piston body 4 is fixedly connected to the middle of the inner side of the cylinder body 1, located outside the guide cylinder 2. The chuck body 6 is fixedly connected to the outer side of the cylinder body 1. The pneumatic telescopic sleeve 7 is fixedly connected to the output end of the piston body 4, sliding outside the guide cylinder 2. The wedge sleeve 11 is fixedly connected to the end of the pneumatic telescopic sleeve 7 away from the piston body 4. The sealing ring 5 is fixedly connected to the inner side of the cylinder body 1. During daily use, the chuck body 6 may accumulate oil. If oil enters the cylinder body 1, it will damage the internal mechanical parts. The sealing ring 5 seals the contact area between the cylinder body 1 and the chuck body 6, significantly reducing the risk of oil intrusion.

[0027] The adjustment mechanism includes a sliding groove 8, a base claw 9, a mating inclined plate 10, a clamping claw 16, and a circular retaining claw 17. Multiple sets of sliding grooves 8 are formed inside the chuck body 6. The base claw 9 is slidably connected inside the sliding groove 8. A mating inclined plate 10 is formed on one side of the bottom of the base claw 9. The mating inclined plate 10 cooperates with the wedge core sleeve 11. A clamping claw 16 is provided on the outer side of the base claw 9. A circular retaining claw 17 is provided at the end of the clamping claw 16 away from the base claw 9. The clamping claw 16 is installed on the outside of the base claw 9 by a threaded connection. When clamping beer kegs of different sizes, the clamping stability will not decrease due to the length limitation of the clamping claw 16. Making the clamping claw 16 detachable not only increases the flexibility of clamping different beer kegs but also further reduces the cost of subsequent maintenance and upkeep of the device.

[0028] The reset mechanism includes a reset groove 12, a limiting post 13, a reset spring 14, and a screw 15. The chuck body 6 has a reset groove 12 near the sliding groove 8. The limiting post 13 is fixedly connected inside the reset groove 12. A base claw 9 is slidably connected to the outside of the limiting post 13. The reset spring 14 is installed on the outside of the limiting post 13. A screw 15 is threadedly connected to the top of the outside of the reset groove 12. The base claw 9 is located at the bottom of the reset spring 14.

[0029] During operation, the device is first connected to an external power source and an air pump, and then connected to an external control module to control the internal electronic components. The external control module is existing technology and should be well known to those skilled in the art, so it will not be described in detail in this technical field.

[0030] First, the cylinder body 1 is installed at the headstock of the machine tool to facilitate subsequent clamping and welding of the beer barrel. When welding of the beer barrel is required, the drive valve plate 3 starts to work. The airflow inside the valve plate 3 is pumped into the piston body 4, driving the piston body 4 to start working. The piston body 4 pushes the pneumatic telescopic sleeve 7 to extend. The pneumatic telescopic sleeve 7 drives the wedge core sleeve 11 to slide outside the guide cylinder 2 and move closer to the mating inclined plate 10. Then, the wedge core sleeve 11 moves closer to the mating inclined plate 10 and squeezes the mating inclined plate 10. The two form a wedge shape and cooperate with each other, converting the lateral force into a longitudinal force. Then, the continued squeezing of the wedge core sleeve 11 drives the base claw 9 to slide inside the sliding groove 8, thereby causing the clamping claw 16 and the ring chuck 17 installed on the outside of the base claw 9 to move closer or further apart.

[0031] As the wedge sleeve 11 pushes the base claw 9 to slide inside the sliding groove 8, the base claw 9 also slides inside the reset groove 12. When the base claw 9 moves upward, the limiting post 13 limits and stabilizes the base claw 9 and the reset spring 14. The base claw 9 compresses the reset spring 14, causing it to deform. At the same time, the reset spring 14 provides a reaction force to the base claw 9 to increase its stability. When the multiple sets of base claws 9 are opened to just hold the beer barrel, the beer barrel is inserted between the ring claws 17. At this time, the piston body 4 begins to release... Gas is released, and the piston body 4 drives the pneumatic telescopic sleeve 7 and the wedge sleeve 11 to retract, causing the wedge sleeve 11 to gradually separate from the mating inclined plate 10. At this time, the return spring 14, which has been deformed by compression, begins to rebound, causing the base claw 9 to clamp and compress the beer barrel. Then, gas is injected into the piston body 4 again, so that the wedge sleeve 11 is in contact with the mating inclined plate 10, limiting the bottom of the base claw 9. This reduces the risk of the beer barrel deforming due to the base claw 9 being suddenly squeezed inward by external force during the beer barrel welding process.

[0032] Meanwhile, different sizes of beer kegs have different thicknesses and weights, and the required clamping force also varies. The screw 15 allows for the replacement and disassembly of the return spring 14. When clamping thicker beer kegs, a stronger return spring 14 is selected, which further increases the stability and reliability of clamping the beer keg.

[0033] By using the adjustment mechanism and the reset mechanism in combination, when clamping beer kegs of different sizes, a reset spring 14 of different strengths is selected to cooperate with it, providing a more stable and safe clamping of the beer kegs. At the same time, the wedge core sleeve 11 and the mating inclined plate 10 adopt a wedge structure, which makes the chuck clamping accuracy high. The use of a circular full-enclosure jaw makes the clamping of beer kegs more reliable and stable. After clamping two sets of beer kegs, they are aligned. At this time, the chuck body 6 is driven to rotate synchronously to complete the welding operation. The high precision and stability of the clamping of beer kegs reduces the risk of poor airtightness due to beer keg displacement during the welding process, further increasing the practicality and reliability of the device.

[0034] Example 2

[0035] like Figure 1 - Figure 5 As shown, a disassembly module 18 is provided at the connection between the circular claw 17 and the clamping claw 16, and a dust cover 19 is fixed to one end of the outer side of the guide cylinder 2.

[0036] During operation, by using the disassembly module 18 and the dust cover 19, the clamping claw 16 and the circular claw 17 are connected through the disassembly module 18, which facilitates the replacement of the specifications and models of the circular claw 17 to adapt it to beer kegs of different diameters. The dust cover 19 protects the inside of the cylinder 1 from dust, further reducing the risk of external dust entering the inside of the cylinder 1 and reducing the risk of shortening the service life of the internal devices of the cylinder 1.
