Description

Technical Field

[0001] This utility model specifically relates to a bottom fixing structure for a tank necking machine. Background Technology

[0002] During tank manufacturing, especially in forming processes such as necking, the tank needs to undergo a series of high-precision and high-intensity processing operations. If the tank is not effectively secured during this process, it is highly susceptible to overall displacement or local deformation under the action of external processing forces, which can affect the dimensional accuracy and appearance quality of the final product, or even cause the product to be scrapped.

[0003] Traditional techniques typically employ clamping devices to position and clamp the tank, such as using mechanical chucks or pneumatic clamps to hold the outer wall of the tank. However, these clamping methods often suffer from uneven force distribution, easily leading to stress concentration at the clamping points and causing localized deformation of the tank, especially when the tank wall is thin or the material strength is low. Furthermore, the complex clamping structure and inconvenient adjustment limit their efficiency in automated production.

[0004] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a highly efficient, stable and compact bottom fixing structure for a tank necking machine.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model provides a bottom fixing structure for a tank necking machine, including a base. The base is provided with a fixing component, which includes a fixed seat, a clamping member, and a push rod slidably connected to the fixed seat for pushing the workpiece out of the clamping member. The clamping member is connected to the fixed seat and has a clamping cavity in the middle for inserting the workpiece. The push rod is slidably connected to the fixed seat and its upper part can extend into the clamping cavity when it slides upward, thereby pushing the workpiece out. The base is also provided with a driving device for driving the push rod to slide up and down.

[0008] As described above, the bottom fixing structure of the tank necking machine has a clamping component that is a ring structure made of elastic soft material, which forms a clamping cavity for inserting the workpiece.

[0009] As described above, the bottom fixing structure of the tank necking machine has a first deformation groove on the upper end face of the clamping member, which extends from the inner ring surface of the clamping member to the outer cylindrical surface of the clamping member.

[0010] As described above, the bottom fixing structure of the tank necking machine has a second deformation groove on the lower end face of the clamping member, which extends from the inner ring surface of the clamping member to the outer cylindrical surface of the clamping member.

[0011] As described above, in the bottom fixing structure of the tank necking machine, the first deformation groove and the second deformation groove are both arranged radially and are evenly distributed circumferentially.

[0012] As described above, in the bottom fixing structure of the tank necking machine, the first deformation groove and the second deformation groove are staggered.

[0013] As described above, in the bottom fixing structure of the tank necking machine, the top of the second deformation groove is higher than the bottom of the first deformation groove, or the top of the second deformation groove is level with the bottom of the first deformation groove.

[0014] As described above, the bottom fixing structure of the tank necking machine has an mounting sleeve connected to the fixing base, and the clamping component is connected to the mounting sleeve.

[0015] As described above, the bottom fixing structure of the tank necking machine has a surrounding plate on the fixing seat that surrounds the mounting sleeve and the clamping parts.

[0016] As described above, the bottom fixing structure of the tank necking machine has a semi-circular or arc-shaped enclosure.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. To prevent workpiece deformation, the clamping element 22, made of elastic and soft material, completely wraps the workpiece, ensuring even distribution of force during fixing and avoiding tank deformation caused by localized stress concentration. Simultaneously, it improves fixing stability and efficiency. The optimized design of the first deformation groove 221 and the second deformation groove 222 ensures that the clamping element 22 produces uniform and stable deformation when the workpiece is inserted, enhancing the fixing effect and improving operational efficiency. This design is particularly suitable for machining environments requiring high-precision fixing.

[0019] 2. Simplified structural design, easy operation and maintenance: The entire fixed structure is designed to be simple, facilitating manufacturing, installation, operation, and maintenance. Furthermore, the design of the enclosure 211 not only protects the internal components but also extends the equipment's service life. Attached Figure Description

[0026] The utility model will be further described below with reference to the accompanying drawings:

[0027] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0028] This utility model discloses a bottom fixing structure for a tank necking machine, used to clamp and fix tank-type workpieces during processing. Addressing the problems of difficulty in fixing tanks during the tightening process and the tendency for traditional clamping methods to deform the tanks, this utility model provides a technical solution with a reasonable structure, stable fixing effect, and convenient operation.

[0029] like Figures 1 to 4 As shown, the structure includes a base 1, on which a fixing component 2 is mounted. The fixing component 2 includes a fixed seat 21, a clamping member 22, and a push rod 23 slidably connected to the fixed seat 21. The clamping member 22 is connected to the fixed seat 21 and has a clamping cavity 20 extending vertically through its center for inserting a workpiece. The push rod 23 is slidably mounted on the fixed seat 21 and can extend its upper part into the clamping cavity 20 when sliding upwards, thereby pushing the workpiece out. In addition, the base 1 is also provided with a driving device 3 for driving the push rod 23 to slide up and down. The driving device 3 can be a conventional actuator such as a hydraulic cylinder, a pneumatic cylinder, or a linear motor, and its output shaft is connected to the push rod 23 to realize the lifting and lowering action of the push rod 23.

[0030] In use, the can is inserted into the clamping cavity 20 of the clamping member 22. Since the clamping cavity 20 and the workpiece have an interference fit, the workpiece can be fixed without the need for traditional clamping methods. This fixing method achieves uniform force distribution by the clamping member 22 completely enveloping the workpiece, effectively avoiding can deformation caused by localized force concentration. The fixed workpiece can be used for subsequent processing or transportation. After processing, the push rod 23 is moved up and down by the drive device 3 to push the workpiece out of the clamping cavity 20. This structure not only provides stable and efficient fixing but also has a simple overall structure and is easy to operate, making it suitable for automated production processes.

[0031] In a preferred embodiment, the clamping member 22 is made of a flexible, soft material and has a ring-shaped structure, such as rubber or silicone, which have good elasticity and friction properties. This ring-shaped structure forms a clamping cavity 20 for inserting the workpiece, such that the inner diameter of the side wall of the clamping cavity 20 is slightly smaller than the outer diameter of the workpiece, thereby ensuring a reliable interference fit when the workpiece is squeezed into the clamping cavity 20. This clamping method can be performed manually or by a robotic arm, improving operational flexibility and automation.

[0032] To ensure that the clamping member 22 can form a uniform and stable deformation in all directions when the workpiece enters the clamping cavity 20, thereby further improving clamping stability, such as... Figures 4 to 6 As shown, the upper end face 2201 of the clamping member 22 is provided with a first deformation groove 221, which extends from the inner ring surface 2202 of the clamping member 22 to the outer cylindrical surface 2203; at the same time, the lower end face 2204 of the clamping member 22 is provided with a second deformation groove 222, which also extends from the inner ring surface 2202 to the outer cylindrical surface 2203.

[0033] As a better implementation method, such as Figures 4 to 6 As shown, the first deformation groove 221 and the second deformation groove 222 are both arranged along the radial direction of the clamping member 22 and are evenly distributed along the circumference to ensure that the clamping member 22 undergoes uniform deformation when subjected to force, thereby improving the stability during the clamping process.

[0034] Furthermore, the first deformation groove 221 and the second deformation groove 222 are staggered in the circumferential direction to optimize the deformation path of the clamping part 22, prevent stress concentration, and improve service life.

[0035] Furthermore, such as Figure 5As shown, the groove depth of the first deformation groove 221 is d1, and the groove depth of the second deformation groove 222 is d2. The sum of the two is equal to the thickness of the clamping member 22. That is, the top of the second deformation groove 222 and the bottom of the first deformation groove 221 are on the same plane; or, the top of the second deformation groove 222 is higher than the bottom of the first deformation groove 221 to form a stepped structure, which helps to control the deformation amount and deformation direction of the clamping member 22.

[0036] As one of the preferred embodiments, such as Figure 3 and Figure 4 As shown, a mounting sleeve 24 is connected to the fixed base 21, and the clamping member 22 is connected to the mounting sleeve 24 by means of bonding or welding, thereby realizing a stable connection between the clamping member 22 and the fixed base 21.

[0037] Furthermore, the fixing base 21 is provided with a surrounding plate 211, which surrounds the mounting sleeve 24 and the clamping member 22, and serves to protect and limit their movement. The surrounding plate 211 is preferably a semi-circular or slightly arc-shaped structure to adapt to the outer contour of the clamping member 22 and provide good spatial adaptability.

[0038] In summary, the bottom fixing structure of the tank necking machine provided by this utility model achieves uniform clamping of the tank workpiece by using elastic clamping parts and interference fit, effectively avoiding the problem of clamping deformation. Moreover, the structure is simple and easy to operate, and has good application prospects and promotion value.

[0039] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
