Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment technology, and more specifically, to a slag cleaning device for welding aluminum alloy pipes. Background Technology

[0002] Aluminum alloy tubes refer to tubular structures made of aluminum alloy materials. They are lightweight, corrosion-resistant, and high-strength, and are widely used in aerospace, automotive, construction and other fields. When welding aluminum alloy tubes, oxides, slag and other residues often remain in the welded area after welding, adhering to the surface or surrounding area of ​​the weld.

[0003] Existing technologies for cleaning weld slag at the weld joints of aluminum alloy pipes often involve manual grinding to remove the slag. This is done by gradually cleaning the slag around the outside of the welded pipe using a grinding and cleaning tool. However, this process requires repeated switching of positions, making continuous cleaning time-consuming and labor-intensive. Furthermore, the actual slag removal effect is poor, resulting in low efficiency and unsatisfactory results. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a welding slag cleaning device for aluminum alloy pipe welding, which has the advantages of automatic and fast cleaning effect and improved cleaning operation environment quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slag cleaning device for welding aluminum alloy pipes, comprising a mounting frame and a handle fixed to the outside of the mounting frame. The mounting frame has an opening, and an assembly arc plate is movably sleeved inside the mounting frame. The inner wall of the assembly arc plate is symmetrically provided with a pushing mechanism, and the movable end of the pushing mechanism is fixedly provided with a rotation cleaning mechanism. A deflection drive assembly is fixedly provided on the outside of the mounting frame, and the deflection drive assembly controls the assembly arc plate to reciprocate within the mounting frame.

[0006] As a preferred embodiment of this utility model, the inner wall of the mounting bracket is provided with an arc-shaped groove, and the interior of the mounting bracket is also provided with an arc-shaped sliding groove, which is symmetrically connected and arranged on the outer side of the arc-shaped groove.

[0007] As a preferred embodiment of this utility model, the top of the assembly arc plate is fixedly connected to an arc-shaped guide plate, and the bottom of the assembly arc plate is fixedly connected to a slider. The arc-shaped guide plate and the slider are respectively slidably arranged in the upper and lower arc-shaped grooves.

[0008] As a preferred embodiment of this utility model, the arc-shaped groove below is further provided with symmetrically fixed positioning blocks, and a spring is fixedly connected between the positioning blocks and the slider.

[0009] As a preferred embodiment of this utility model, the deflection drive assembly includes a motor, a gear, and an arc gear. The motor is fixed to the outside of the mounting bracket via a motor frame. The gear is fixedly sleeved on the output shaft of the motor. The arc gear is fixedly disposed on the outer surface of the mounting arc plate, and the gear meshes with the arc gear.

[0010] The preferred embodiment of this utility model describes a rotating cleaning mechanism comprising a mounting base, a second motor, an intermediate rod, and a cleaning brush. The cleaning brush is disposed on the outer side of the intermediate rod. The lower end of the intermediate rod is rotatably mounted in the mounting base via a bearing. The second motor is fixed to the bottom of the mounting base via a bracket, and the output shaft of the second motor is fixedly connected to the intermediate rod. The movable end of the pushing mechanism is fixedly connected to the mounting base.

[0011] As a preferred embodiment of this utility model, the mounting frame is provided with a detachable suction and filtration mechanism at its top. The detachable suction and filtration mechanism includes an arc-shaped cavity, a sealing frame, a suction pump, a filter screen, a connecting frame, and a suction pipe. The arc-shaped cavity is located at the top of the mounting frame, the sealing frame is fixed at the top of the arc-shaped cavity, the lower end of the connecting frame passes through the sealing frame and extends into the arc-shaped cavity, the filter screen is fixed in the arc-shaped cavity, the suction pump is fixed on the outside of the mounting frame, and the suction end of the suction pump is connected to the arc-shaped cavity. The suction pipes are evenly spaced and connected at the top of the connecting frame. The front of the sealing frame is provided with a locking screw, which is used to fix and clamp the connecting frame fitted into the sealing frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model involves mounting a frame along an opening onto the aluminum alloy tube to be treated, keeping the arc-shaped area of ​​the mounting frame located outside the weld seam of the aluminum alloy tube. Two sets of pushing mechanisms are activated, controlling two sets of rotating cleaning mechanisms to move synchronously and contact the outside of the weld seam. Motor 2 in the rotating cleaning mechanism is activated, driving the cleaning brush supported by the steel brush to rotate via the central rod, and performing friction cleaning along the outside of the weld seam. The deflection drive assembly is activated, with motor 1 driving the gear to rotate, which in turn drives the meshing arc-shaped gear to rotate. This causes the assembled arc-shaped plate to move along an arc-shaped groove along an arc-shaped trajectory via the arc-shaped guide plate, thereby driving the rotating cleaning mechanism inside the assembled arc-shaped plate to rotate around the weld seam, automatically switching the cleaning position. After the assembled arc-shaped plate deflects at a certain angle, the deflection drive assembly reverses, causing the assembled arc-shaped plate to rotate again along the arc-shaped trajectory in the opposite direction, dynamically cleaning along the outside of the arc-shaped weld seam in a different direction. This quickly completes the surrounding cleaning of the weld seam, achieving automatic surrounding cleaning of the weld seam on the outer surface of the aluminum alloy tube. The operation is simple and the cleaning efficiency is high.

[0014] 2. This utility model uses a suction pump to draw air from the arc-shaped cavity during cleaning operations. Air is also drawn outward through the connecting frame and suction pipe, drawing dust from the cleaning process into the arc-shaped cavity and filtering it onto the top of the filter screen. This achieves the collection and absorption of dust during the removal of welding slag, preventing it from dispersing into the air and affecting the working environment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides a slag cleaning device for welding aluminum alloy pipes, including a mounting frame 1 and a handle fixed to the outside of the mounting frame 1. The mounting frame 1 has an opening, and an assembly arc plate 3 is movably sleeved inside the mounting frame 1. A pushing mechanism 5 is symmetrically provided on the inner wall of the assembly arc plate 3. A rotation cleaning mechanism 6 is fixedly provided on the movable end of the pushing mechanism 5. A deflection drive assembly 4 is fixedly provided on the outside of the mounting frame 1. The deflection drive assembly 4 controls the assembly arc plate 3 to reciprocate within the mounting frame 1.

[0023] The mounting bracket 1 has an arc-shaped groove 2 on its inner wall and an arc-shaped sliding groove 11 inside. The arc-shaped sliding groove 11 is symmetrically connected to the outside of the arc-shaped groove 2. An arc-shaped guide plate 7 is fixedly connected to the top of the mounting arc-shaped plate 3 and a slider 8 is fixedly connected to the bottom of the mounting arc-shaped plate 3. The arc-shaped guide plate 7 and the slider 8 are respectively slidably arranged in the upper and lower arc-shaped sliding grooves 11. A positioning block 10 is symmetrically fixed inside the lower arc-shaped sliding groove 11. A spring 9 is fixedly connected between the positioning block 10 and the slider 8.

[0024] By cooperating with the arc-shaped guide plate 7 and the top arc-shaped slide groove 11, and with the appropriate fitting of the assembly arc plate 3 in the arc-shaped groove 2, the assembly arc plate 3 can rotate stably and can rotate along the arc-shaped trajectory. Furthermore, through the elasticity of the spring 9, in conjunction with the connection of the positioning block 10 and the slider 8, damping and traction for reciprocating rotation are provided, further maintaining the stable deflection of the assembly arc plate 3 and facilitating reset.

[0025] The deflection drive assembly 4 includes a motor 41, a gear 42, and an arc gear 43. The motor 41 is fixed to the outside of the mounting bracket 1 by a motor frame. The gear 42 is fixedly sleeved on the output shaft of the motor 41. The arc gear 43 is fixedly set on the outer side of the mounting arc plate 3. The gear 42 and the arc gear 43 are meshed and connected.

[0026] The rotation of gear 42 drives the meshing arc gear 43 to deflect, causing the assembled arc plate 3 to rotate around the outside of the aluminum alloy tube at a certain angle. This ensures that the rotating cleaning mechanism 6 always removes weld slag along the outside of the weld. Furthermore, the reciprocating deflection further expands the range of motion, avoiding the need for the handheld device to rotate around the weld. The handheld device can automatically complete the comprehensive cleaning of the weld around the weld, resulting in high cleaning efficiency.

[0027] The rotating cleaning mechanism 6 includes a mounting base 61, a second motor 62, an intermediate rod 63, and a cleaning brush 64. The cleaning brush 64 is located on the outside of the intermediate rod 63. The lower end of the intermediate rod 63 is rotatably mounted in the mounting base 61 through a bearing. The second motor 62 is fixed to the bottom of the mounting base 61 by a bracket, and the output shaft of the second motor 62 is fixedly connected to the intermediate rod 63. The movable end of the pushing mechanism 5 is fixedly connected to the mounting base 61.

[0028] The outer cleaning brush 64 is rotated by the middle rod 63 to remove the welding slag by friction along the weld. Alternatively, a scraper or grinding protrusion can be set on the outer side of the middle rod 63 to achieve the friction cleaning of welding slag. The pushing mechanism 5 is specifically an electric push rod.

[0029] The mounting frame 1 has a detachable suction and filtration mechanism on its top. The detachable suction and filtration mechanism includes an arc-shaped cavity 12, a sealing frame 13, a suction pump 14, a filter screen 15, a connecting frame 16, and a suction pipe 17. The arc-shaped cavity 12 is located on the top of the mounting frame 1. The sealing frame 13 is fixed on the top of the arc-shaped cavity 12. The lower end of the connecting frame 16 passes through the sealing frame 13 and extends into the arc-shaped cavity 12. The filter screen 15 is fixed in the arc-shaped cavity 12. The suction pump 14 is fixed on the outside of the mounting frame 1, and the suction end of the suction pump 14 is connected to the arc-shaped cavity 12. The suction pipes 17 are evenly spaced and connected to the top of the connecting frame 16. The front of the sealing frame 13 is provided with a locking screw, which is used to fix and clamp the connecting frame 16, which is fitted into the sealing frame 13.

[0030] The suction pump 14 provides suction power, which, together with the connected arc-shaped cavity 12, the connecting sleeve 16 and the suction pipe 17, completes the air intake and sucks in the dust from the cleaning processing area. The filter screen 15 performs filtration, and can be a dense filter material such as filter cloth. The filter screen 15 can be fixed in the arc-shaped cavity 12 in a detachable manner, specifically by bolt fixing or snap-fit ​​fixing, which is convenient for removal and cleaning. The inner wall of the sealing sleeve 15 is provided with a sealing gasket to ensure the sealing performance of the sealing sleeve 13 when it is fitted.

[0031] The working principle and usage process of this utility model are as follows: When using, hold the handle and slide the mounting bracket 1 along the opening onto the aluminum alloy tube to be treated, keeping the arc-shaped area of ​​the mounting bracket 1 located outside the weld seam of the aluminum alloy tube. Activate the two sets of pushing mechanisms 5, controlling the two sets of rotating cleaning mechanisms 6 to move synchronously and contact the outside of the weld seam. Activate the second motor 62 in the rotating cleaning mechanism 6, which drives the cleaning brush 64 supported by the steel brush to rotate via the intermediate rod 63, and performs friction slag removal along the outside of the weld seam. Activate the deflection drive assembly 4, where the first motor 41 drives the gear 42 to rotate, and the gear 42 drives the meshing arc-shaped gear 43 to rotate, causing the assembly arc-shaped plate 3 to move along the arc-shaped guide plate 7 along the arc-shaped groove 2 along an arc trajectory, thereby driving the inner side of the assembly arc-shaped plate 3... The rotating cleaning mechanism 6 rotates around the weld, automatically switching the cleaning position. After the assembled arc plate 3 deflects at a certain angle, the deflection drive component 4 reverses, causing the assembled arc plate 3 to rotate again along the arc trajectory and change direction to dynamically clean along the outside of the arc weld, quickly completing the cleaning around the weld. During cleaning, the suction pump 14 is started to draw air from the arc cavity 12 and draws air outward through the connecting sleeve 16 and suction pipe 17, sucking the dust in the cleaning process into the arc cavity 12 and filtering it on the top of the filter screen 15. When cleaning is required, the locking bolts on the front of the sealing sleeve 13 are loosened, the sealing sleeve 13 is removed, and the filter screen 15 is cleaned along the top opening of the arc cavity 12.
