Description

Technical Field

[0001] The present invention relates to the technical field of welding bases, and more specifically, to a steel structure welding slag cleaning device. Background Art

[0002] After traditional steel structure welding is completed, in order to make the welding points firm, repeated welding is required. During the welding process, cleaning residues, grinding, and knocking are the most important processes. The existing technology mainly drives a wire wheel by a motor to grind and clean the weld seam. However, there will be welding slag at the weld seam position, and the high-temperature molten welding slag will adhere to the surface of the weld seam. Before processing the weld seam, it is necessary to manually knock off the welding slag and then perform grinding and cleaning. The existing technology lacks knocking on the weld seam position, and simply relying on the wire disc is difficult to ensure the cleaning effect of the welding slag. Summary of the Invention

[0003] The purpose of the present invention is to provide a steel structure welding slag cleaning device to solve the problems raised in the above background art.

[0004] The present invention adopts the following technical solutions:

[0005] A steel structure welding slag cleaning device includes:

[0006] A frame for installing a sliding table structure, and at the same time, a plurality of conveying rollers for bearing are rotatably connected to the top of the frame;

[0007] A sliding table structure for installing and driving a cleaning component to move;

[0008] A cleaning component, which includes a mounting seat, a cleaning shaft, a grinding disc, a swing arm, a pressing rod, and a knocking block. The mounting seat is installed on the sliding table structure, the cleaning shaft is rotatably connected to the mounting seat, the grinding disc is fixedly connected to the cleaning shaft, a motor is fixedly provided on one side of the mounting seat, the motor drives the cleaning shaft, the pressing rod is fixedly connected to the cleaning shaft, the swing arm is elastically connected to the mounting seat, and the knocking block is fixedly connected to the swing arm; the end of the pressing rod is connected to the circumferential surface of the cleaning shaft. The cleaning component further includes a spring, the spring is fixedly connected to the bottom of the swing arm, and the end of the spring is fixedly connected to the mounting seat.

[0009] Further, an integrally formed ear plate is provided on one side of the mounting seat, and the swing arm is rotatably connected to the ear plate through a pin shaft.

[0010] Further, the knocking block and the pressing rod are respectively located on both sides of the pin shaft. The knocking block forms a block structure with a trapezoidal cross-section, and the knocking block is welded to the end of the swing arm.

[0011] Further, the sliding table structure includes a guide rail, a first sliding seat, a second sliding seat, a lead screw, a linear motor, and an adjustment motor. The guide rail is fixedly connected to the machine frame. The first sliding seat is slidably connected to the guide rail. The second sliding seat is slidably connected to the first sliding seat. The lead screw is threadedly connected to the second sliding seat, and both ends of the lead screw are rotatably connected to the first sliding seat. The adjustment motor is installed on the top of the first sliding seat, and the lead screw is fixedly connected to the output shaft of the adjustment motor. The output end of the linear motor is connected to the mounting seat, and the mounting seat is slidably connected to the second sliding seat.

[0014] Beneficial effects

[0015] In the present invention, the cleaning shaft drives the pressing rod to rotate. When the pressing rod rotates above the swing arm, the pressing rod can push the swing arm to flip around the pin shaft. Under the lever action, the end of the swing arm where the knocking block is installed is lifted upward. As the pressing rod separates from the swing arm, the swing arm resets under the pushing action of the spring, that is, the swing arm drives the knocking block to accelerate and move downward below the mounting seat. When the mounting seat is on one side of the welded part, the knocking block intermittently knocks the weld position multiple times to make the welding slag fall off, and then it is polished and cleaned by the grinding disc. Integrating the knocking of the welding slag and the grinding and cleaning improves the cleaning efficiency and effect, and the structure is compact and the design is reasonable.

[0016] In the present invention, by pushing the first sliding seat to slide along the guide rail, the adjustment motor drives the lead screw to rotate so that the mounting seat vertically displaces along the limiting rod, and the push rod pushes the mounting seat to linearly slide along the rectangular groove of the second sliding seat. Furthermore, the three-axis displacement of the mounting seat can be realized, and the positions of the grinding disc and the knocking block can be flexibly adjusted to meet the cleaning of the weld and the welding slag, reduce the cleaning blind area, and is flexible to use and simple to adjust.

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The present invention discloses a steel structure welding slag cleaning device, as Figure 1 shown, including:

[0026] A frame 10, on the top of which a plurality of conveying rollers 11 for bearing are rotatably connected;

[0027] A sliding table structure for installing and driving the cleaning component to move;

[0028] A cleaning component, which is arranged on one side of the frame 10 for cleaning the weld seam. The cleaning component includes a mounting seat 30, a cleaning shaft 31, a grinding disc 32, a swing arm 33, a pressing rod 34 and a knocking block 35. The mounting seat 30 is movably arranged on one side of the frame 10. The cleaning shaft 31 is rotatably connected to the mounting seat 30. The grinding disc 32 is fixedly connected to the cleaning shaft 31. A motor is fixedly arranged on one side of the mounting seat 30, and the motor drives the cleaning shaft 31. The pressing rod 34 is fixedly connected to the cleaning shaft 31. The swing arm 33 is elastically connected to the mounting seat 30, that is, the swing arm 33 can be deflected under an external force. The knocking block 35 is fixedly connected to the swing arm 33. The pressing rod 34 can push the swing arm 33 to rotate; the end of the pressing rod 34 is connected to the circumferential surface of the cleaning shaft 31. The pressing rod 34 can rotate above the swing arm 33 to make the swing arm 33 flip by a certain angle. An integrally formed ear plate 37 is arranged on one side of the mounting seat 30. The swing arm 33 is rotatably connected to the ear plate 37 through a pin shaft 38. The knocking block 35 and the pressing rod 34 are respectively located on both sides of the pin shaft. The knocking block 35 forms a block structure with a trapezoidal cross-section. The knocking block 35 is welded to the end of the swing arm 33. The cleaning component further includes a spring 36. The spring 36 is fixedly connected to the bottom of the swing arm 33. The end of the spring 36 is fixedly connected to the mounting seat 30.

[0029] In this embodiment, the cleaning shaft 31 is rotated by a motor, and the grinding disc 32 at the end of the cleaning shaft 31 is driven to rotate to brush and clean the weld position. Considering that the welding slag has a certain hardness, before cleaning, it is necessary to manually tap the weld position with a hammer to make the welding slag fall off, and then use the grinding disc 32 to further grind and clean the weld position. In order to omit the manual tapping step, the pressure rod 34 is driven to rotate by the cleaning shaft 31. When the pressure rod 34 rotates above the swing arm 33, the pressure rod 34 can push the swing arm 33 to flip around the pin shaft, and the swing arm 33 is lifted upward. As the pressure rod 34 separates from the swing arm 33, the swing arm 33 is reset under the pushing action of the spring 36, that is, the swing arm 33 drives the knocking block 35 to accelerate and move downward below the mounting seat 30. When the mounting seat 30 is located on one side of the welded part, the knocking block 35 intermittently knocks the weld position multiple times to make the welding slag fall off, and then it is polished and cleaned by the grinding disc 32. By integrating the knocking of the welding slag and the grinding and cleaning, the present invention improves the cleaning efficiency and effect, has a compact structure and a reasonable design.
