Description

Technical Field

[0001] This utility model belongs to the field of cylindrical processing technology, specifically relating to a support device for welding thin-walled cylindrical cylinders. Background Technology

[0002] Currently, most circumferential welding of large thin-walled cylinders adopts horizontal assembly, using a support fixture to overcome the deformation caused by its own weight, and aligning the various cylinder sections circumferentially before circumferential welding. However, due to the thin wall thickness and large cylinder diameter, the support fixture alone often cannot completely eliminate the influence of the cylinder's own weight deformation. Moreover, the positioning accuracy between cylinders is often not guaranteed during horizontal assembly, resulting in uneven stress on the cylinder in various directions during welding, and making it difficult to control the amount of misalignment and deformation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a support device for welding thin-walled cylinders.

[0004] The technical solution adopted to solve the above-mentioned technical problems is: a support device for welding thin-walled cylinders, including a support base, a groove installed on the top edge of the support base, a slider slidably installed inside the groove, a first linear guide module installed on the top of the slider, an installation column installed on the moving end of the first linear guide module, a connecting block hinged to the top of the installation column, an installation block hinged to the side of the connecting block, a pressure roller installed on the bottom surface of the installation block, a second linear guide module installed on the bottom surface of the support base, an arc-shaped clamping plate installed on the moving end of the second linear guide module, a fixing frame installed on the side of the support base, an electrical control device installed on the top of the fixing frame, a power supply device installed on the bottom of the fixing frame, and a rubber block installed on the side of the installation column facing the arc-shaped clamping plate.

[0005] Furthermore, the chute is annular and has an opening perpendicular to the location of the power supply equipment. These features are designed to prevent the closed structure from interfering with the welding process.

[0006] Furthermore, the top of the support base is provided with a long sliding hole that is adapted to and penetrates the moving end of the second linear guide module, thereby enabling the arc-shaped clamp to move smoothly.

[0007] Furthermore, the second linear guide module consists of four symmetrically arranged units on the support base. Through the above, combined with the arc-shaped clamp installed on the mobile end, a good fit can be achieved inside the cylinder.

[0008] Furthermore, the number of sliders is no less than four, and a pressure-sensitive sensor electrically connected to the electronic control equipment is installed inside the rubber block. Through the above, combined with the components installed on the sliders, a larger area of ​​contact with the cylinder can be achieved, and the clamping effect can be observed by the output signal of the pressure-sensitive sensor.

[0009] Furthermore, the electrical control equipment is electrically connected to the power supply equipment, the first linear guide module, and the second linear guide module. Through the above, the electrical control equipment controls the linear guide module.

[0010] The beneficial effects of this utility model are as follows: This utility model, through its designed components, can vertically support a cylinder for welding operations, and the device can effectively clamp the cylinder. Combined with the designed components, the cylinder can maintain effective clamping regardless of its position on the device. The electrical connection between the electrical control equipment and each component enables precise control of the device. Through the pressure signal fed back by the pressure sensor, the electrical control equipment can adjust the motion parameters of the linear guide module in real time, ensuring a good clamping effect.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] like Figures 1 to 3 As shown, a support device for welding thin-walled cylinders in this embodiment includes a support base 1, which is the basic component of the entire device and provides a stable support platform for the installation and operation of other components.

[0015] The support base 1 serves as the core support structure of the entire device, and a slide groove 2 is installed on its top edge. The design of the slide groove 2 is crucial, as it provides a track for the sliding of the slider 3. The slide groove 2 is annular, and this annular design allows the slider 3 to move in a circular motion within a certain range, increasing the flexibility of the device's movement. At the same time, the slide groove 2 has an opening perpendicular to the location of the power supply device 13, and this opening facilitates subsequent welding work.

[0016] The top of the support base 1 is also provided with a long sliding hole that is adapted to and passes through the moving end of the second linear guide module 9. The function of this long sliding hole is to ensure that the moving end of the second linear guide module 9 can move smoothly in a straight line on the support base 1, reducing the phenomenon of jamming during the movement.

[0017] The slider 3 is installed inside the groove 2 and can slide freely within the groove 2. There are no fewer than four sliders 3; the use of multiple sliders 3 can improve the fit to the cylinder.

[0018] The second linear guide module 9 consists of four modules symmetrically arranged on the support base 1. This symmetrical arrangement allows the device to maintain balance and stability during movement, and the arc-shaped clamp 10 provides better and more comprehensive coverage of the cylinder's side surface. The main function of the linear guide module is to achieve linear motion; its moving end can make precise linear displacements along the guide rail. The moving end of the first linear guide module 4 is equipped with a mounting post 5. When the moving end of the first linear guide module 4 moves, it will drive the mounting post 5 to move as well.

[0019] A connecting block 6 is hinged to the top of the mounting column 5, allowing the connecting block 6 to rotate at a certain angle relative to the mounting column 5. A mounting block 7 is hinged to the side of the connecting block 6, and similarly, the mounting block 7 can also rotate relative to the connecting block 6. Through these two hinged connections, the movement of the mounting block 7 is more flexible, and its angle can be adjusted according to actual needs. A pressure roller 8 is mounted on the bottom surface of the mounting block 7, which can be used for operations such as pressing the inner wall of the cylinder. When the mounting column 5 moves under the drive of the first linear guide module 4, the pressure roller 8 also moves accordingly, thereby achieving pressing of the cylinder wall at different positions.

[0020] A second linear guide module 9 is mounted on the bottom surface of the support base 1, and an arc-shaped clamping plate 10 is mounted on the moving end of the second linear guide module 9. The function of the second linear guide module 9 is to drive the arc-shaped clamping plate 10 to move linearly. The arc-shaped design of the arc-shaped clamping plate 10 is to better conform to the shape of the inner wall of the cylinder, and to more effectively fix and clamp the inner wall of the cylinder. When it is necessary to fix the inner wall of the cylinder, the moving end of the second linear guide module 9 drives the arc-shaped clamping plate 10 closer to the cylinder until the cylinder is clamped.

[0021] A mounting bracket 11 is installed on the side of the support base 1, serving to install and secure other equipment. An electrical control device 12 is installed on the top of the mounting bracket 11. The electrical control device 12 is the control center of the entire device, responsible for controlling the movement of each linear guide module and receiving sensor signals. A power supply device 13 is installed at the bottom of the mounting bracket 11, providing power to the entire device and ensuring the normal operation of all components. The electrical control device 12 is electrically connected to the power supply device 13, the first linear guide module 4, and the second linear guide module 9. Through this electrical connection, the electrical control device 12 can precisely control the movement speed, direction, and displacement parameters of each linear guide module.

[0022] A rubber block 14 is installed on the side of the mounting column 5 opposite the arc-shaped clamping plate 10. The rubber block 14 serves as a buffer and protector. When the mounting column 5 collides or comes into contact with the arc-shaped clamping plate 10, the rubber block 14 can absorb part of the impact force, preventing damage to the components. A pressure-sensitive sensor, electrically connected to the electrical control device 12, is installed inside the rubber block 14. The pressure-sensitive sensor can detect changes in pressure. When the pressure-sensitive sensor detects that the pressure reaches a certain value, it transmits a signal to the electrical control device 12. The electrical control device 12 then performs corresponding control operations based on the received signal, such as stopping the movement of the linear guide module, thereby achieving precise control of the device. The working principle of this embodiment is as follows: the device is based on the coordinated movement between the components and the precise control of the electronic control device 12. When the cylinder needs to be placed outside the arc-shaped clamping plate 10 for welding, the electronic control device 12 first controls the movement of the moving end of the second linear guide module 9, driving the arc-shaped clamping plate 10 closer to the cylinder. Then, the electronic control device 12 controls the movement of the moving end of the first linear guide module 4, which drives the mounting column 5 to move, clamping and fixing the cylinder. During the pressing process, the pressure sensor inside the rubber block 14 detects the pressure change in real time and feeds the signal back to the electronic control device 12. If the pressure is too low, the electronic control device 12 will adjust the movement parameters of the linear guide module in time to ensure good fit to the cylinder. When the cylinder is placed inside the arc-shaped clamping plate 10, the rotation of the connecting block 6 and the mounting block 7 allows the pressure roller 8 to be attached to the inner side of the cylinder, thereby cooperating with the arc-shaped clamping plate 10 to hold and fix the cylinder, thus facilitating subsequent processing of the cylinder's interior. In this way, the device can fix and press cylinders of different shapes and sizes, exhibiting strong versatility and adaptability. The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
