Description

Technical Field

[0001] This utility model relates to the field of welding actuator installation, and in particular to a truss structure for installing large welding actuators. Background Technology

[0002] Large welding equipment is used for welding large structural workpieces. It generally consists of a worktable, a welding mounting mechanism, and a welding actuator. During installation, the welding mounting mechanism spans the worktable, and the welding actuator is mounted on the welding mounting mechanism. However, due to the heavy weight of the welding actuator in existing large welding equipment, conventional welding mounting mechanisms present the following problems when supporting the welding actuator:

[0003] 1. Prone to malfunctions: Due to the weight of the welding actuator, the welding installation mechanism is prone to sagging and shifting during use, causing the welding position of the welding actuator to shift, which affects the welding operation effect and quality.

[0004] 2. Because the welding actuators need to be installed and supported, most existing welding installation mechanisms adopt fixed installation structures, which cannot drive the welding actuators to make adaptive displacement adjustments, thus limiting the operating range of large welding equipment. Utility Model Content

[0030] The installation and use process of the truss structure for installing the large welding actuator of this utility model is as follows:

[0031] I. The installation process is as follows:

[0032] First, the installers can install the bottoms of the left support frame 1 and the right support frame 2 on the working ground. Then, a first guide rail 3, which guides the lateral displacement mechanism 4, is laid on the left support frame 1 and the right support frame 2. A lateral slider 41 is slidably installed on the first guide rail 3. The lower part of the lateral truss beam assembly 42 is bolted to the lateral slider 41. Next, the bidirectional output drive unit 43 is installed. Specifically, the bidirectional drive motor assembly 431 can be installed in the middle position of the lateral truss beam assembly 42 to drive the left rail wheel. Group 434 and right rail wheel group 435 are in operation; two sets of drive shafts 343 for outputting rotational torque are provided on the bidirectional drive motor group 431. The bidirectional drive motor group 431 drives the first connecting shaft 432 and the second connecting shaft 433 to rotate through the two sets of drive shafts 343 respectively. Then, the first connecting shaft 432 is connected to the left rail wheel group 434, and the second connecting shaft 433 is connected to the right rail wheel group 435. The left rail wheel group 434 and the right rail wheel group 435 are connected by the bearing seat 341, bearing box 342, drive shaft 343 and rail. The system consists of a track wheel 344; a bearing housing 342 can be installed on a bearing seat 341, a support bearing can be installed inside the bearing housing 342, a drive shaft 343 can be installed on the support bearing, and the track wheel 344 can be fixedly installed on the drive shaft 343. After the above installation is completed, the longitudinal displacement mechanism 5 can be installed, and a longitudinal slide rail and rack can be installed on the transverse truss; then, the longitudinal slider 52 is slidably engaged on the longitudinal slide rail, and the moving frame 51 is installed on the longitudinal slider 52 by bolt connection, and the mounting support frame 53 and the rotating... The motor 54 is mounted on the moving frame 51. A meshing gear 55 is installed on the outer end of the motor shaft of the rotary motor 54, which meshes with the rack for transmission. Finally, the actuator mounting part 6 is installed. During installation, the left bracket 61 and the right bracket 62 can be mounted on the mounting support frame 53. One end of the connecting rod 63 is connected to the left bracket 61, and the other end of the connecting rod 63 is connected to the right bracket 62. The disc support 64 is mounted on the connecting rod 63 to support the installation of the large welding actuator. The installation process of this utility model is now complete.

[0033] II. In practical use, the installer can install the actuator mounting part 6 on the disc-shaped support 64. The disc-shaped support 64 is located between the left bracket 61 and the right bracket 62. The left bracket 61 and the right bracket 62 work together to support the connecting rod 63 and the disc-shaped support 64, thus providing stable support for the welding actuator. When it is necessary to adjust the lateral displacement of the welding actuator, the operator can control the bidirectional drive motor group 431 in the bidirectional output drive unit 43 to work. 431 can drive the first connecting shaft 432 and the second connecting shaft 433 to rotate through two sets of drive shafts 343 respectively. The first connecting shaft 432 is connected to the left rail wheel group 434 and drives the track wheel 344 in the left rail wheel group 434 to rotate on the left support frame 1. The second connecting shaft 433 is connected to the right rail wheel group 435 and drives the track wheel 344 in the right rail wheel group 435 to rotate on the right support frame 2. At this time, the bidirectional output drive unit 43 can drive the transverse truss beam group 42 to make lateral displacement adjustment on the first guide rail 3.

[0034] When longitudinal displacement adjustment of the welding actuator is required, the operator can control the rotary motor 54 in the longitudinal displacement mechanism 5. The rotary motor 54 drives the meshing gear 55 to rotate via the motor shaft. Since the meshing gear 55 meshes with the rack on the transverse truss beam group 42, under the action of the meshing force, the rotary motor 54 can drive the moving frame 51 to move on the longitudinal slide rail via the longitudinal slider 52. At this time, the mounting support frame 53 on the moving frame 51 can drive the actuator mounting part 6 and the welding actuator on it to achieve longitudinal displacement adjustment. The above shows and describes the basic principle, main features and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of this utility model as claimed.
