Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a welding fixture for a loader hood frame. Background Art

[0002] The hood frame is an important component of the loader hood. Although its structure is simple, the whole machine shakes greatly during the loader shoveling operation, so the hood frame must ensure sufficient strength; the hood door must be installed on the hood frame, and the gap between the hood door and the front and rear hoods must be consistent. At the same time, the hood frame is installed on the rear frame, so the overall size of the hood frame must be guaranteed after welding.

[0003] The existing loader hood frame welding fixture requires one hand to press the hood frame to fix it, and the other hand to rotate the wheel to make the forward screw push the movable clamp forward to press against the hood frame, and then repeat the operation to drive the other side fixing plate to move and fix it. The operation is relatively complicated and time-consuming, and lacks certain practicality. Utility Model Content

[0028] When ready for use, the shell 11 is placed at a designated position, and then the loader hood frame is placed inside the shell 2 12. Then, the operator drives the rotating plate 25 to rotate on the shell 2 12 through the driving mechanism 26. The rotating plate 25 drives the multiple driving rods 27 to move simultaneously in the groove 22 on the same side, so that the driving rod 27 squeezes the moving block 21 to move. The multiple moving blocks 21 move through the connecting plate 23 to drive the multiple fixing plates 24 to move toward the hood frame at the same time, thereby fixing the hood frame from multiple directions at the same time, without the need for the operator to adjust the fixing plates 24 in multiple directions respectively. The joints are fixed, thereby improving the work efficiency of the operator; the operator connects the power supply of the servo motor 261 and turns on the servo motor 261, and the output end of the servo motor 261 drives the gear 262 to rotate, and through the engagement with the toothed belt 263, the gear 262 drives the rotating plate 25 to rotate, thereby driving multiple fixed plates 24 at the same time, thereby improving the convenience of the device; the outer wall of each fixed plate 24 is provided with friction patterns, and the friction patterns can increase the friction force between the contact surface of the fixed plate 24 and the hood frame, further preventing the hood frame from shifting during welding, thereby improving the stability of the device.

[0029] Embodiment 2

[0030] See also Figure 1-4 , based on the first embodiment, an auxiliary function is added;

[0031] A spring 6 is provided on each of the connecting plates 23, and both ends of each of the springs 6 are respectively fixedly connected to the outer wall of the connecting plate 23 and the outer wall of the fixed plate 24; a baffle 4 is fixedly connected to the top of the rotating plate 25; a slider 5 is fixedly connected to the bottom of the rotating plate 25, and a plurality of sliders 5 are provided, and each of the sliders 5 is slidably connected to the top of the shell 2 12.

[0032] When in use, after the fixed plate 24 contacts the hood frame, the connecting plate 23 continues to move the extrusion spring 6 to compress the spring 6, and the spring 6 is used to buffer the pressure of the fixed plate 24 on the hood frame to prevent the operator from being unable to judge the degree of fixation of the hood frame during fixation, resulting in the hood frame being squeezed and damaged, thereby improving the safety of the device; a baffle 4 is fixedly connected to the top of the rotating plate 25, and the rotating plate 25 drives the baffle 4 to move at the same time when the rotating plate 25 rotates. The baffle 4 can cover the gap between the rotating plate 25 and the toothed belt 263, thereby preventing dust and other debris from falling into the interior of the shell 11 through the gap, making it inconvenient for the operator to clean, thereby improving the operator's work efficiency; a slider 5 is fixedly connected to the bottom of the rotating plate 25, and the rotating plate 25 slides on the top of the shell 2 12 through the slider 5. Since the slider 5 is T-shaped, it can prevent the rotating plate 25 from being skewed when the top drive mechanism 26 is running, thereby improving the stability of the device.
