Description

Technical Field

[0001] This utility model relates to the field of tank assembly welding technology, specifically a guide mold structure for a tank assembly welding machine. Background Technology

[0002] A tank is a sealed container used to store liquids or gases. Tank production involves assembling and welding rolled cylinders and end caps to form a complete tank. Welding methods include submerged arc welding, manual electric arc welding, and argon arc welding.

[0003] The assembly of the cylinder and the head requires ensuring their coaxiality, so that the cylinder and the head are concentric and the welds are aligned. Currently, a mold that mimics the shape of the head is commonly used to place the head. The internal contour of the mold is consistent with the shape of the head. Since the axial position of the mold is easy to determine, the mold and the head are then moved to align with the cylinder and assembled. However, for the assembly of cylinders and heads of different diameters, different molds are required. The existing molds are integrally formed, and changing the mold requires changing the base on the mold used to move the head, which increases the cost of the mold and occupies space. Utility Model Content

[0004] In order to solve the problems in related technologies, this utility model provides a guide mold structure for a tank assembly welding machine. This device solves the problem that welding cylinders and end caps of different diameters requires changing the corresponding molds. Since the mold is integrally formed, the base also needs to be replaced, resulting in high mold costs and thus high tank assembly costs.

[0005] To solve the above problems, the following technical solutions are provided: This utility model discloses a guide mold structure for a tank assembly welding machine, comprising: A platform, wherein a support seat is rotatably mounted on the side wall of the platform via a slewing bearing; A positioning part that conforms to the shape of the end cap, the positioning part being used to place the end cap, the positioning part being connected to the support base via a gasket; The positioning part has a positioning hole, and the gasket has a mounting hole that matches the positioning hole.

[0006] The above solution utilizes a support base and a positioning part. The support base and the platform are connected. The support base has a gasket with mounting holes, and the positioning part has positioning holes. The positioning holes and mounting holes are matched, and bolts are screwed into the positioning holes and mounting holes in sequence, thus installing the positioning part on the support base. Installation and disassembly are convenient. Moving the platform moves the positioning part. The positioning part conforms to the shape of the end cap to be processed, and the inner wall shape of the positioning part matches the outer contour of the end cap. The end cap is placed inside the positioning part, and the end cap and the positioning part are concentric. When assembling cylinders and end caps of different diameters, the bolts are unscrewed from the positioning part to remove it, and a positioning part matching the end cap is replaced. The matching positioning part is then installed on the support base with bolts, and the end cap is placed inside the positioning part. By changing the positioning part, end caps of different diameters can be placed inside the positioning part and installed on the platform. The concentricity between the end cap and the positioning part facilitates assembly with the cylinder without the need to replace the platform, reducing the cost of tank assembly.

[0007] Furthermore, the slewing bearing includes an outer ring and an inner ring that are rotatably connected, with the outer ring sleeved on the outside of the inner ring; The inner ring is connected to the base, and the outer ring is connected to the support base.

[0008] The above solution uses a slewing bearing with the outer ring connected to the support base and the inner ring connected to the pedestal, thereby mounting the positioning part on the pedestal. The slewing bearing can simultaneously withstand axial force, radial force, and overturning moment, facilitating rotation during welding of the end cap and the cylinder and ensuring rotational stability.

[0009] Furthermore, a rolling element is connected between the outer ring and the inner ring. The rolling element is annular, and the outer ring rotates on the inner ring.

[0010] The above solution uses a slewing bearing to allow the end cap to rotate within the positioning section, which in turn causes the positioning section and the support seat to rotate. The support seat then drives the outer ring to rotate on the inner ring. The rolling elements within the slewing bearing reduce friction and transmit force. The slewing bearing provides support and load-bearing capacity, facilitating the rotation and welding of the end cap.

[0011] Furthermore, the inner wall of the positioning part is provided with a connecting surface, and the connecting surface is annular; The positioning part is provided in multiple ways, and the inner diameter of the connecting surface of the multiple positioning parts is different.

[0012] The above solution uses multiple positioning parts. Since the diameters of the multiple end caps are different, each positioning part with the same diameter as the end cap needs to be used. By using the inner diameter of the connecting surface with the diameter of the end cap, the end cap can be placed inside the positioning part and concentric with the positioning part, thus adapting to various end caps.

[0013] Furthermore, the positioning part is connected to the support base by bolts being screwed into the positioning hole and the mounting hole in sequence.

[0014] The above solution involves disassembling and installing the positioning part and the support base using bolts, thereby installing the positioning part on the pedestal. This method facilitates easy installation and disassembly, and makes it convenient to replace the positioning part to fit the end cap.

[0015] Furthermore, the platform is provided with a channel running through both ends of the platform, and the channel, the slewing bearing, the support base and the positioning part are coaxial and connected.

[0016] The above solution uses a channel to connect a drive device. The drive device enters the positioning part through the channel and drives the end cap to rotate. Since the positioning part is similar in shape to the end cap, the positioning part, support base and outer ring rotate with the end cap, which facilitates the welding of the tank body.

[0017] The above solution has the following advantages: The guide mold structure of the tank assembly welding machine of this utility model includes a platform and a positioning part detachably connected to the platform. The positioning part is detachably connected to the platform via a support base. A positioning part matching the end cap to be processed is selected, and the positioning hole on the positioning part is aligned with the mounting hole of the gasket on the support base. Bolts are screwed into the positioning hole and mounting hole to connect the positioning part to the support base. The end cap is placed inside the positioning part and concentric with it. The platform is moved to assemble the end cap with the cylinder, ensuring the coaxiality of the end cap and the cylinder. After the tank welding is completed, the bolts are unscrewed to remove the positioning part, and a new positioning part matching the next end cap is installed on the platform to continue tank assembly and welding. The detachable connection between the positioning part and the platform allows for easy installation and disassembly of tanks of different diameters, requiring only the replacement of the positioning part without replacing the platform. This reduces the cost of tank assembly. Attached Figure Description

[0020] 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.

[0021] In specific embodiment 1, such as Figures 1-5 As shown, the present invention discloses a guide mold structure for a tank assembly welding machine. The guide mold structure for a tank assembly welding machine includes: a base 1 and a positioning part 3. The base 1 and the positioning part 3 are detachably connected. By disassembling and installing the positioning part 3 on the base 1, it is possible to adapt to end caps of different diameters.

[0022] The support base 2 is provided on the side wall of the pedestal 1. The support base 2 is a hollow cylinder. The pedestal 1 has a channel 11 that runs through both ends of the pedestal 1. The channel 11 is connected to the support base 2 and is coaxial.

[0023] In this embodiment, the positioning part 3 is contoured to the end cap, and the inner wall shape of the positioning part 3 is consistent with the outer contour of the end cap. The end cap is placed inside the positioning part 3, and the end cap and the positioning part 3 are concentric. The positioning part 3 is a hollow cylinder. One end of the positioning part 3 is used to insert the end cap, and the other end of the positioning part 3 is used to connect with the support base 2. The positioning part 3 and the support base 2 are connected and coaxial.

[0024] like Figure 3 and Figure 4 As shown, the positioning part 3 is connected to the support base 2 via a gasket 21. The positioning part 3 has a positioning hole 31, and the gasket 21 has a mounting hole 22 that matches the positioning hole 31. Fasteners such as bolts are screwed into the positioning hole 31 and the mounting hole 22 in sequence to install the positioning part 3 on the support base 2, making installation and disassembly convenient. One end of the gasket 21 is connected to the support base 2, and the other end of the gasket 21 is detached from the positioning part 3 for installation and disassembly. By replacing different positioning parts 3, the positioning hole 31 on the positioning part 3 is aligned with the mounting hole on the gasket 21, thereby allowing for the disassembly, installation, and replacement of the positioning part 3.

[0025] like Figure 5As shown, the inner wall of the positioning part 3 is provided with a connecting surface 31, which is annular and conforms to the shape of the end cap. Multiple positioning parts 3 are provided, and the inner diameter of the connecting surface 31 of the multiple positioning parts 3 is different. Since the diameters of the multiple end caps are different, positioning parts 3 with the same diameter as each end cap are required to make the end cap concentric with it inside the positioning part 3. By using the inner diameter of the connecting surface 31 to be the same as the diameter of the end cap, the end cap can be placed inside the positioning part 3 and concentric with the positioning part 3, thereby adapting to various end caps.

[0026] like Figure 6 and Figure 7 As shown, in specific embodiment 2, based on embodiment 1, a slewing bearing 4 is provided between the platform 1 and the support 2. The slewing bearing 4 includes an outer ring 41 and an inner ring 42 that are rotatably connected. The outer ring 41 is sleeved on the outside of the inner ring 42. A rolling element 43 is connected between the outer ring 41 and the inner ring 42. The rolling element 43 is annular, and the outer ring 41 rotates on the inner ring 42. The inner ring 42 is connected to the platform 1, and the outer ring 41 is connected to the support 2. The slewing bearing 4 is coaxial with and connected to the channel 11 and the support 2.

[0027] It should be noted that the slewing bearing 4 is used to realize the relative rotational motion of two objects and can simultaneously withstand axial force, radial force and overturning moment. The channel 11 can be used to connect the drive device. The drive device enters the positioning part 3 from the channel 11 and drives the end cap to rotate. The end cap rotates in the positioning part 3. Since the positioning part 3 is contoured to the end cap, the end cap drives the positioning part 3 and the support seat 2 to rotate. The support seat 2 drives the outer ring 41 to rotate on the inner ring 42. The rolling element 43 reduces friction and transmits force in the slewing bearing 4. The slewing bearing 4 plays a supporting and load-bearing role and facilitates the rotation and welding of the end cap. The slewing bearing 4 is common knowledge to those skilled in the art and will not be described in detail.

[0028] During operation, select the positioning part 3 that matches the end cap to be processed, align the positioning hole 31 on the positioning part 3 with the mounting hole 22 of the gasket 21 on the support base 2, and use bolts to screw into the positioning hole 41 and mounting hole 22 to connect the positioning part 3 to the support base 2; place the end cap inside the positioning part 3 and concentrically with the positioning part 3, move the platform 1 to assemble the end cap with the cylinder, and ensure the coaxiality of the end cap and the cylinder; after the tank body is welded, unscrew the bolts to remove the positioning part 3, replace it with a positioning part 3 that matches the next end cap, install it on the platform 1, and continue to assemble and weld the tank body.

[0029] After the end cap and cylinder are assembled, the end cap and cylinder need to be rotated for welding. The channel 11 can be used to connect the drive device. The drive device enters the positioning part 3 from the channel 11 and drives the end cap to rotate. The end cap rotates in the positioning part 3. Since the positioning part 3 is contoured to the end cap, the end cap drives the positioning part 3 and the support seat 2 to rotate. The support seat 2 drives the outer ring 41 to rotate on the inner ring 42. The slewing bearing 4 simultaneously bears the axial force, radial force and overturning moment to ensure the stability of the structure rotation. The positioning part 3 and the base 1 are detachably connected. For tank assembly of different diameters, only the positioning part 3 needs to be replaced without replacing the base 1. The installation and disassembly are convenient, reducing the cost of tank assembly.
