Description

Technical Field

[0001] This utility model relates to the technical field of welding equipment, and in particular to a welding mechanism for a corn harvester traction frame. Background Technology

[0002] A corn harvester is an agricultural implement used to harvest corn stalks when corn is mature or near maturity, according to agronomic requirements. The corn harvester frame is constructed from multiple welded components, each component consisting of multiple welded parts. During welding, the plates need to be positioned and clamped. Existing technology publication CN217193446U proposes a welding workbench for processing corn combine harvesters, including a base, support plate, welding seat, drive unit, rotating shaft, clamping arm, and worm gears. The bottom of the welding seat is horizontally rotatably connected to the drive shaft, and the two ends of the drive shaft along its length are respectively equipped with a first worm segment and a second worm segment with opposite helical directions. Two worm gears mesh with the first and second worm segments, respectively. However, this design makes it inconvenient to adjust the position of the traction frame components and to weld different parts, requiring re-clamping, resulting in low welding efficiency and consequently low production efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a welding mechanism for a corn harvester traction frame that facilitates the adjustment of the welding position, makes it easy to weld different parts, and improves welding efficiency.

[0004] This utility model discloses a welding mechanism for a corn harvester traction frame, comprising a base, multiple support legs, a worktable, a protective cover, a geared motor, an adjustment assembly, a clamping assembly, a placement assembly, and a welding assembly. Multiple support legs are axially and evenly mounted on the bottom of the base. The protective cover is fixedly installed in the center of the bottom end of the base. The geared motor is fixedly installed inside the protective cover, with its output end rotatably penetrating the base and connecting to the center of the bottom end of the worktable. A limiting groove is formed on the top of the base, and a supporting rotating ring is rotatably installed within the limiting groove. The top of the supporting rotating ring is connected to the bottom of the worktable. The clamping assembly is mounted via the adjustment assembly. At the top left and right ends of the workbench, the placement component is installed at the center of the top of the workbench, and the welding component is installed on the rear side wall of the base. The traction frame component is placed on the placement component and pushed between the clamping components. The adjustment component adjusts the clamping position to clamp the traction frame component. The welding component welds the traction frame component. At the same time, the clamping component can drive the traction frame component to rotate during welding, allowing welding to be performed at different positions on the traction frame component. The reduction motor is started to drive the workbench to rotate above the base, which can adjust the position of the traction frame component, making it easier to weld the traction frame component and improving welding efficiency.

[0005] Preferably, the clamping assembly includes two upright plates, two drive boxes, two gearboxes, two servo motors, two rotating shafts, and two clamping blocks. The upright plates are located at the top left and right ends of the worktable. The drive boxes are fixedly installed on the upper outer wall of the upright plates. The gearboxes are fixedly installed inside the drive boxes. The input end of the gearbox is connected to the output end of the servo motor. The output end of the gearbox is connected to the rotating shaft. The rotating shaft is rotatably installed on the upper part of the upright plate. The clamping blocks are fixedly installed at the ends of the two rotating shafts that are close to each other. The traction frame component is placed between the two clamping blocks for clamping. The servo motors are started to drive the rotating shafts to rotate through the gearboxes. The rotating shafts drive the clamping blocks to rotate, which in turn drives the traction frame component to rotate, thereby adjusting the position of the traction frame component for easy welding.

[0006] Preferably, the two clamping blocks have clamping grooves at their close ends. A dual-output motor is rotatably installed in the middle of the clamping groove. The output ends of the dual-output motor are connected to lead screws. Two sliding blocks are symmetrically screwed onto the outer walls of the upper and lower lead screws and are slidably installed in the clamping groove. A clamping plate is fixedly installed on the outer wall of the sliding block. After the traction frame component is located between the two clamping plates, the dual-output motor is started to drive the lead screws to rotate. The lead screws drive the two sliding blocks to move in the clamping groove, thereby driving the clamping plates to clamp the traction frame component.

[0007] Preferably, multiple telescopic rods are installed at one end of the two clamping plates that are close to each other, and a contact plate is installed at the other end of the telescopic rod. A spring is fitted on the outer wall of the telescopic rod. When clamping, the contact plate contacts the traction frame component, and the traction frame component can be pre-clamped by the telescopic rod and the spring to ensure the stability after clamping.

[0008] Preferably, the adjustment assembly includes two electric telescopic rods and two adjusting sliders. Adjustment slots are provided at the left and right ends of the top of the worktable. The two electric telescopic rods are symmetrically installed on the left and right side walls of the worktable, with the telescopic ends of the electric telescopic rods located in the adjustment slots. The adjusting sliders are slidably installed in the adjustment slots, and the telescopic ends of the electric telescopic rods are fixedly connected to the adjusting sliders. The top end of the adjusting sliders is connected to the bottom end of the upright plates. Activating the electric telescopic rods pushes the adjusting sliders to move within the adjustment slots, which can adjust the distance between the two upright plates, thereby adjusting the distance between the two clamping blocks, facilitating the loading and unloading of the traction frame components and improving practicality.

[0009] Preferably, the welding assembly includes a support frame, a support sleeve, a hydraulic cylinder, a welding machine, a second gearbox, an adjusting screw, a second servo motor, reinforcing ribs, and a telescopic arm. The bottom of the support frame is fixedly connected to the rear side wall of the base. The support sleeve is fixedly installed on the top of the support frame. Reinforcing ribs are obliquely installed between the bottom of the support sleeve and the front end of the support frame. The telescopic arm is slidably installed inside the support sleeve. The second gearbox is fixedly installed on the rear side wall of the support sleeve. The output end of the second gearbox is connected to the output end of the second servo motor. The output end of the second gearbox is connected to an adjusting screw, which is rotatably installed inside the support sleeve. The telescopic arm is screwed onto the outer wall of the adjusting screw. The support sleeve is fixedly installed at the front end of the telescopic arm. The welding machine is fixedly installed at the bottom of the hydraulic cylinder. During welding, the hydraulic cylinder is started to push the welding machine downward to weld the traction frame component. The second servo motor is started to drive the adjusting screw to rotate through the second gearbox, which can push the telescopic arm to move within the support sleeve, thereby adjusting the welding position for convenient use.

[0010] Preferably, the placement assembly includes a support cylinder, a forward and reverse motor, a threaded rod, a lifting column, and a placement plate. The support cylinder is fixedly installed at the top center of the workbench, and an installation groove is provided at the bottom of the inner part of the support cylinder. The forward and reverse motor is fixed in the installation groove, and the threaded rod is fixedly installed at the output end of the forward and reverse motor. The lifting column is slidably installed inside the support cylinder, and the middle part of the lifting column is screwed onto the outer wall of the threaded rod. The placement plate is fixedly installed on the top of the lifting column. After the traction frame component is placed on the top of the placement plate, the forward and reverse motor is started to drive the threaded rod to rotate, which can push the lifting column upward, thereby pushing the traction frame component upward, making it easier to clamp, reducing the handling intensity, and reducing the labor intensity of the workers.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the traction frame component is placed on the placement assembly, the traction frame component is pushed between the clamping assemblies, the adjustment assembly adjusts the clamping position to clamp the traction frame component, the welding assembly welds the traction frame component, and at the same time the clamping assembly can drive the traction frame component to rotate during welding, welding different positions of the traction frame component, and starting the reduction motor drives the worktable to rotate above the base, which can adjust the position of the traction frame component, facilitate the welding of the traction frame component, and improve welding efficiency.
