Description

Technical Field

[0001] This utility model relates to the field of welding workbench technology, and in particular to a portable, movable welding rotary workbench. Background Technology

[0002] Large centrifugal chiller units are primarily formed by connecting their core components via stainless steel piping assemblies in a specific sequence. These assemblies are mainly composed of different types of pipes and flanges welded together. During welding, it is necessary to adapt to diverse pipe specifications and curvatures. However, due to positional limitations during welding, especially with large-diameter pipes, welders often need to pause three to four times while completing a single weld, manually rotating parts or moving to the next welding position before continuing. This frequent interruption not only affects welding efficiency but can also increase the number of weld joints, leading to abnormal grain growth at the weld joints due to localized overheating, resulting in a decline in mechanical properties such as reduced strength and toughness. Furthermore, the intergranular region at the weld joints may increase the risk of intergranular corrosion due to the segregation of impurities and inclusions. More seriously, uneven internal stress distribution can lead to the rapid propagation of microcracks and even stress corrosion failure. These problems ultimately severely impact the service life of the piping assembly, increasing maintenance and replacement costs. Some existing welding equipment can rotate, but the rotation process is complex and not suitable for novice operators. Summary of the Invention

[0003] This utility model provides a portable, mobile welding rotary workbench to solve the problems in the prior art, such as the inability to achieve continuous welding of pipe assemblies in one go and the impact of multiple weld joints on service life.

[0004] According to one aspect of the present invention, a portable movable welding rotary table is provided, comprising: a support base and a clamping table, wherein the bottom of the clamping table is provided with a raceway groove, and the top of the support base is provided with a ball bearing. When the clamping table rotates, the ball bearing rolls in the raceway groove, thereby causing the clamping table and the support base to rotate relative to each other. The support base is also provided with a drive motor, the output end of which is connected to the clamping table and drives the clamping table to rotate.

[0005] Furthermore, the support base includes a support base plate and a support column fixed to the support base plate, with a freely rolling ball at the top of the support column.

[0006] Furthermore, there are at least three support columns, which are arranged symmetrically on the support base plate so that the positions of the support columns correspond to the positions of the raceway grooves.

[0007] Furthermore, a ball wheel for controlling the movement of the balls is provided at the top of the support column. Preferably, the inner diameter of the ball wheel is equal to the diameter of the balls.

[0008] Furthermore, the clamping workbench is uniformly provided with dovetail grooves, and multiple dovetail grooves are evenly distributed radially along the radial direction.

[0009] Furthermore, the center of the clamping worktable is recessed inward to form a recessed platform.

[0010] Furthermore, the table surface of the clamping workbench is also evenly provided with mounting holes.

[0011] Furthermore, the bottom of the supporting base plate is equipped with casters.

[0012] Furthermore, the drive motor is a continuously variable speed motor.

[0013] Furthermore, the drive motor is fixed to the support base plate via a motor mounting bracket.

[0014] Furthermore, the support column and motor mounting base are welded and fixed to the support base plate.

[0015] The beneficial effects of this utility model embodiment are as follows: By improving the support base and clamping worktable, this utility model adds an automatic rotation function, enabling continuous welding during the welding process. This eliminates time losses caused by frequent stops and repositioning, reduces the number of weld joints, and effectively reduces the risk of intergranular corrosion and stress corrosion, as well as the problem of microcrack propagation caused by uneven internal stress. It not only improves the durability and safety of the pipe assembly but also extends its service life and reduces maintenance and replacement costs.

[0016] By adding a continuously variable speed motor, the rotation speed can be adjusted according to the welder's requirements, ensuring uniform weld seams and improving welding quality. The inclusion of casters with brakes enhances the portability and flexibility of the welding rotary table, making it suitable for various welding environments and easy to move.

[0017] This utility model has a simple structure and is easy to operate, and has significant advantages in improving efficiency, ensuring quality, reducing costs, and enhancing the versatility and adaptability of equipment.

[0026] This utility model provides a portable and movable welding rotary worktable, including: a support base and a clamping worktable 3. The bottom of the clamping worktable 3 is provided with a raceway groove 5, and the top of the support base is provided with a ball bearing 4. When the clamping worktable 3 rotates, the ball bearing 4 rolls in the raceway groove 5, thereby causing the clamping worktable 3 to rotate relative to the support base. The support base is also provided with a drive motor, and the output end of the drive motor is connected to the clamping worktable 3 and drives the clamping worktable 3 to rotate.

[0027] During operation, the drive motor rotates the clamping table 3, causing the ball bearings 4 on top of the support to roll along the raceway 5. The support ensures the stability of the clamping table 3, preventing instability from affecting the welding effect. Using a drive motor to rotate the clamping table 3 ensures continuous welding, avoiding frequent stops and repositioning required by manual rotation, resulting in better welding quality and fewer weld joints. The ball bearings on top of the support reduce friction between the support and the raceway 5 during relative movement.

[0028] To ensure effective support, the support base includes a support base plate 1 and a support column 2 fixed to the support base plate 1. The top of the support column 2 is equipped with freely rolling ball bearings 4. The ball bearings 4 cooperate with the raceway groove 5 to accurately limit the position of the support base and achieve stable rotation of the clamping worktable 3.

[0029] There are at least three support columns 2, which are centrally symmetrically arranged on the support base plate 1, so that the positions of the support columns 2 correspond to the positions of the raceway groove 5. In a preferred embodiment, there are four support columns 2, which are symmetrically arranged and distributed on the circumference of the raceway groove 5.

[0030] The top of the support column 2 is provided with a ball wheel 10 for controlling the movement of the balls. Preferably, the inner diameter of the ball wheel 10 is equal to the diameter of the balls 4. One end of the ball wheel 10 is bent inward so that the diameter of the opening is slightly smaller than the diameter of the other parts. The ball wheel 10 is used to support and control the balls 4 and prevent the balls from rolling off.

[0031] To facilitate the fixing of the connector assembly, dovetail grooves 7 are evenly arranged on the surface of the clamping workbench 3, with multiple dovetail grooves 7 radially distributed evenly along the radial direction. These dovetail grooves 7, in conjunction with various pressure plates and clamps, are used to ensure the fixing of various types of connector assemblies.

[0032] The center of the clamping worktable 3 is recessed inward to form a concave platform.

[0033] The table surface of the clamping workbench 3 is also evenly provided with mounting holes 9. The mounting holes 9 match the dovetail grooves 7 to ensure the fixation of various pressure plates and clamps, thereby achieving the reliability of the welding process.

[0034] The bottom of the support base plate 1 is equipped with casters 6, and a braking mechanism is installed on the casters 6. The welding rotary worktable can be moved by the casters 6, so that the welding rotary worktable can be moved to the required place at will. The braking mechanism is used to brake and ensure the stability of the worktable during the operation.

[0035] To ensure the forward and reverse rotation of the clamping worktable 3, and to control the rotation speed of the clamping worktable 3 as needed, the drive motor is a stepless speed-regulating motor.

[0036] The drive motor is fixed to the support base plate 1 via the motor mounting bracket 8.

[0037] To ensure the stability of the overall structure of the welding rotary worktable, the support column 2 and the motor mounting base 8 are welded and fixed to the support base plate 1 to form an integrated structure, which is more stable.
