Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to gantry robot welding equipment. Background Technology

[0002] In modern industrial production, welding is an important processing technology widely used in various fields such as machinery manufacturing, automobile manufacturing, and steel structure processing. With the continuous development of industrial automation, increasingly higher requirements are being placed on the precision, efficiency, and versatility of welding equipment.

[0003] Traditional welding equipment often suffers from simple clamping structures when performing welding operations. This makes it difficult to flexibly adjust the clamping structure according to different specifications and shapes of workpieces, resulting in low clamping accuracy and easy shaking during the welding process, which affects the welding quality and may even cause welding defects. This also severely limits the applicability of the equipment. Therefore, we propose a gantry robot welding equipment to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a gantry robot welding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A truss robotic welding device includes: a robotic welding machine and a worktable. The top of the worktable has two sets of side plates and a clamping assembly. A top plate is fixedly installed on the top of the two sets of side plates. A lead screw is rotatably mounted inside the top plate. A movable plate is threadedly connected to the outer side of the lead screw. Two sets of support plates are provided on one side of the movable plate. A second lead screw is rotatably mounted inside the two sets of support plates. A movable seat is threadedly connected to the outer side of the second lead screw. A third lead screw is rotatably mounted inside the movable seat. A mounting seat is threadedly connected to the outer side of the third lead screw. The robotic welding machine is positioned on one side of the mounting seat. The clamping assembly... The components include: a base plate, multiple sets of clamps, and a bidirectional lead screw. The bidirectional lead screw is rotatably mounted inside the base plate. Two sets of guide blocks are slidably mounted on the top of the base plate. The two sets of guide blocks are threadedly connected to the outside of the bidirectional lead screw. A sliding plate is fixedly mounted on the top of each of the two sets of guide blocks. A screw is rotatably mounted inside each of the two sets of sliding plates. A threaded sleeve is threadedly connected to the outside of each of the two sets of screws. Four sets of connecting plates are slidably mounted on one side of each of the two sets of sliding plates. Four sets of support rods are threadedly connected between the four adjacent sets of connecting plates and the corresponding threaded sleeves. The multiple sets of clamps are arranged on the outside of the corresponding connecting plates.

[0006] Preferably, the movable plate is slidably mounted on the bottom of the top plate, the mounting base is slidably mounted on one side of the movable base, and the clamping assembly further includes: a drive motor and two sets of adjusting motors. The drive motor is fixedly mounted on one side of the base plate, one end of the bidirectional lead screw is fixedly mounted on the output end of the drive motor, the two sets of adjusting motors are fixedly mounted on one side of the corresponding sliding plate, and one end of the two sets of screws is fixedly mounted on the output end of the corresponding adjusting motor. A controller is provided on one side of one set of the side plates.

[0007] Preferably, a linear motor is fixedly installed on one side of the top plate, and one end of the lead screw is fixedly installed on the output end of the linear motor. A linear motor is fixedly installed on one side of one set of support plates, and one end of the lead screw is fixedly installed on the output end of the linear motor. A linear motor is fixedly installed on the top of the movable seat, and one end of the lead screw is fixedly installed on the output end of the linear motor.

[0008] Preferably, the top of the base plate is provided with two sets of sliding grooves, and the two sets of guide blocks are slidably installed in the corresponding sliding grooves.

[0009] Preferably, each of the two sets of sliding plates has four sets of limiting grooves on one side, and the four sets of connecting plates are slidably installed in the corresponding limiting grooves.

[0010] Preferably, a guide groove is provided on one side of the movable plate, and the movable seat is slidably installed in the guide groove.

[0011] In this invention, the truss robot welding equipment uses a controller to control a linear motor to rotate a lead screw. Since the moving plate is threadedly connected to the lead screw and slidably mounted on the bottom of the top plate, the rotation of the lead screw is converted into linear movement of the moving plate along the direction of the lead screw. A second linear motor is controlled to rotate the lead screw, and the moving seat, threadedly connected to the lead screw and restricted by a guide groove, moves linearly along the direction of the lead screw. A third linear motor is controlled to rotate the lead screw, and the mounting seat threadedly connected to it slides vertically, thereby enabling the robot welding machine mounted on one side of the mounting seat to achieve precise displacement in three directions. This meets the welding requirements of different positions, effectively ensuring the movement accuracy of the welding machine in three directions, satisfying the stringent position control requirements of high-precision welding operations, greatly expanding the equipment's applicability, eliminating the need for dedicated welding equipment for specific workpieces, and improving the equipment's versatility and economy. This utility model features a reasonable structural design. A controller regulates the rotation of the screw driven by the adjusting motor. The screw is threadedly connected to a threaded sleeve, which, constrained by the support rod, connecting plate, and limiting groove, moves linearly outside the screw. This, in turn, pushes the connecting plate along the limiting groove, allowing for more precise positional adjustments of multiple clamping fixtures and ultimately securing the workpiece. The drive motor then rotates a bidirectional lead screw. Two guide blocks, threaded to the bidirectional lead screw and slidably mounted in grooves on the top of the base plate, move relative to or away from each other along the grooves under the action of the lead screw. This, along with the top sliding plate, moves the two clamping fixtures closer together or further apart, allowing the clamped workpieces to be joined. This design avoids workpiece wobbling during welding due to unstable clamping, greatly improving clamping accuracy. The equipment can adapt to workpieces of different specifications and shapes, enhancing its versatility. The entire process is seamless and automated, effectively shortening the production cycle and improving the overall efficiency and quality stability of welding operations.
