Description

Technical Field

[0001] The utility model relates to the technical field of aluminum pipe processing, in particular to a processing device for aluminum pipe welds. Background Technique

[0002] When aluminum pipes are connected, the connection parts need to be welded. After welding, obvious welds will be formed at the welding parts. In order to make the welded aluminum pipes more beautiful, the welding parts need to be polished. At present, there is no equipment that can quickly polish the welds of aluminum pipes integrally.

[0003] The utility model with the publication number CN216731159U proposes an integrated device for grinding and polishing the outer welds of aluminum pipe profiles, which relates to the technical field of aluminum pipe processing. The technical solution in the existing patent document records that "by controlling the first motor to rotate, driving the screw rod and the sliding seat to rotate in a threaded manner, driving the sliding seat to move along the outer surface of the screw rod to the weld position, then controlling the two second cylinders to extend, driving the mounting block and the second motor to move, so that the grinding wheel and the polishing wheel are respectively attached to both sides of the weld, and controlling the second motor to rotate to synchronously grind and polish the weld. At the same time, by controlling the third motor to rotate, driving the mounting turntable and the aluminum pipe to rotate, and then quickly grinding and polishing the welds on the outer surface of the aluminum pipe".

[0004] However, the above-mentioned existing technology still has the following deficiencies when in use: 1. The grinding of the weld is usually carried out step by step. For example, when initially grinding, a grinding disc with coarse particles is selected to quickly remove the protruding weld. The polishing wheel used for polishing has smaller particles to improve the smoothness. However, the above-mentioned existing technology grinds and polishes the weld simultaneously, which will greatly reduce the service life of the polishing wheel, and the polishing effect is not good due to the interference of the grinding wheel; 2. At present, the welding of aluminum pipes mainly includes offline prefabrication and on-line welding. Among them, offline prefabrication means welding before installation, and on-line welding means welding after the aluminum pipes are erected on site. Obviously, the above-mentioned existing technology does not have the function of grinding and processing on-line welds, that is, it does not have a portable grinding function.

[0005] Therefore, the utility model provides a processing device for aluminum pipe welds. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a processing device for aluminum pipe welds to solve the problems put forward in the above background technology. The utility model has the advantages of being more convenient to replace different grinding belts, improving the quality of the weld after grinding, and also having the advantage of portable on-line grinding, being suitable for grinding and processing the welds of on-line aluminum pipes, and having good portability.

[0007] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a processing device for aluminum tube welds, comprising a base and a driving motor, a bracket is inserted into the top of the base, and a bracket located on both sides of the bracket is arranged on the top of the base, a V-shaped plate with a small end facing the base is arranged on the top of one side of the bracket, and a supporting wheel is arranged at the free end and the sharp corner of the V-shaped plate, one side of the V-shaped plate is connected to a tensioning wheel located in the V-shaped plate through a tensioning rod, the supporting wheel and the tensioning wheel on the V-shaped plate are connected through a grinding belt, the driving motor is fixedly arranged on one side of the V-shaped plate and its output shaft is fixedly connected to the supporting wheel located at the tip of the V-shaped plate, and the tail of the driving motor is fixedly connected to an auxiliary rod.

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a processing device for aluminum pipe welds, including a base 1 and a driving motor 2. The bracket 3 is plugged into the top of the base 1, that is to say, the bracket 3 can be disassembled. Specifically, a square socket can be opened on the base 1, and then a square plug inserted into the square socket can be welded at the bottom of the bracket 3.

[0023] On the top of the base 1, brackets 9 are provided on both sides of the bracket 3. The brackets 9 play a role in lifting the two welded aluminum pipes, so that the aluminum pipes are in a horizontal state.

[0024] On the top of one side of the bracket 3, there is a V-shaped plate 4 with the small end facing the base 1. The aluminum tube lifted by the bracket 9 passes through the inner groove of the V-shaped plate 4. Support wheels 5 are arranged at the free end and the sharp corners of the V-shaped plate 4. One side of the V-shaped plate 4 is connected with a tensioning wheel 7 located inside the V-shaped plate 4 through a tensioning rod 6. The support wheel 5 and the tensioning wheel 7 on the V-shaped plate 4 are connected by a grinding belt 8. At this time, the tensioned grinding belt 8 forms a V-shaped groove structure. The welds of the two aluminum tubes will squeeze the grinding belt 8, and the grinding belt 8 and the aluminum tube welds are in a state of double-sided contact. When the grinding belt 8 rotates, it can grind the welds.

[0025] The preferred connection method of the tensioning rod 6, the tensioning wheel 7 and the V-shaped plate 4 is that a horizontal plate 41 near the bottom is welded on one side of the V-shaped plate 4. The tensioning rod 6 includes a guide rod 61 and a spring 62. The guide rod 61 penetrates through the middle of the top of the horizontal plate 41 and is in a sliding connection. A stop disk 611 is welded at the bottom of the guide rod 61, and a support shaft 612 rotatably connected with the tensioning wheel 7 is welded at its top. The spring 62 is sleeved on the guide rod 61 and is located between the stop disk 611 and the horizontal plate 41. The spring 62 exerts a downward elastic tension on the guide rod 61, so that the tensioning wheel 7 can tension the grinding belt 8.

[0026] When grinding, it is necessary to hold the aluminum tube by hand to stabilize it. It should be noted that grinding is different from turning. The friction generated by grinding is relatively small, so it is easy for manual operation to control whether the aluminum tube rotates. When manually twisting the grinding belt 8, the grinding position of the weld can be switched. When manually bending the aluminum tube laterally with force, the local position of the weld on the aluminum tube can press the grinding belt 8, so as to perform targeted grinding on the parts with larger local protrusions on the weld, and overall improve the grinding efficiency and the appearance quality after grinding. Among them, when in use, grinding belts 8 with different particle sizes of grinding surfaces are prepared. By replacing the grinding belt 8, the aluminum tube welds can be ground and polished step by step, thus greatly improving the quality after grinding and prolonging the service life of the grinding belt 8.

[0027] The above-mentioned driving motor 2 is fixedly arranged on one side of the V-shaped plate 4 and its output shaft is fixedly connected with the support wheel 5 at the tip of the V-shaped plate 4. The driving motor 2 provides driving force for the rotation of the support wheel 5. Among them, an auxiliary rod 21 is fixedly connected to the tail of the driving motor 2. The auxiliary rod 21 is a hand-held part. When the bracket 3 is removed, the bracket 3 and the auxiliary rod 21 can be held to perform portable grinding on the aluminum tube welds at high places or on the line. When grinding, only by swinging the bracket 3, the grinding belt 8 can comprehensively grind the welds.

[0028] In this embodiment, the bracket 9 includes a lifting vertical rod 91 and a V-shaped rod 92 fixedly arranged at the top of the lifting vertical rod 91. The V-shaped rod 92 serves to support the aluminum tube. The setting of the lifting vertical rod 91 facilitates the adjustment of the height of the V-shaped rod 92, which is suitable for lifting aluminum tubes with different outer diameters. The bottom of the lifting vertical rod 91 is fixedly connected to the top of the base 1. Rotating rollers 921 are rotatably connected to the two side walls inside the V-shaped rod 92. When in use, the rotating rollers 921 are in contact with the aluminum tube, aiming to reduce the friction of the aluminum tube during rotation.

[0029] Specifically, the lifting vertical rod 91 includes a bottom sleeve 911, a vertical column 912 with one end sleeved inside the bottom sleeve 911, and a locking bolt 913. The bottom of the bottom sleeve 911 is welded to the upper end surface of the base 1, and a threaded hole for screwing with the locking bolt 913 is provided on its outer peripheral wall. When the locking bolt 913 is loosened, the vertical column 912 can be easily pulled up and down to adjust the height of the V-shaped rod 92. When the locking bolt 913 is tightened, the vertical column 912 can be fixed on the bottom sleeve 911. Among them, a handle 9131 is welded to one end of the locking bolt 913. The handle 9131 is a hand-held part, which is convenient for screwing the locking bolt 913.

[0030] In this embodiment, a dial 101 is rotatably connected to the middle of one side of the cross plate 41. One side of the dial 101 is hinged to the outer peripheral wall of the retaining disc 611 through a connecting rod 102. When the dial 101 is manually moved up and down, the connecting rod 102 cooperates with the spring 62 to drive the guide rod 61 to move up and down. This setting has the advantage of making it more labor-saving and convenient to replace the grinding belt 8.

[0031] Working principle: Before use, replace the coarse-grained grinding belt 8. When in use, place the welded aluminum tube on the rotating rollers 921 on the two V-shaped rods 92, so that the weld seam contacts the V-shaped groove wall of the grinding belt 8. Then start the driving motor 2, the supporting wheels 5 rotate, the grinding belt 8 runs and grinds the weld seam. Due to the action of friction, the aluminum tube will show a slight sign of following rotation. At this time, manually hold the aluminum tube, and then manually turn the aluminum tube. During this process, observe the grinding effect of the weld seam and control the rotation and stop of the aluminum tube according to the grinding effect. When polishing is required, hold the dial 101 and press it, the tensioning wheel 7 moves up, replace the fine-grained grinding belt 8, and then polish the weld seam. When grinding the weld seam of the aluminum tube at high altitude, pull out the bracket 3, and then hold the bracket 3 and the auxiliary rod 21 to swing and grind the weld seam of the aluminum tube at high altitude.

[0032] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
