Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a tubular metal welding and fixing device. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. The types of workpieces that need to be welded are becoming increasingly diverse. The development trend of pipeline welding will be digitalization, intelligence, environmental protection and automation through continuous technological innovation, the formulation of standards and specifications and international cooperation and exchanges.

[0003] Patent CN210908767U discloses a magnetic base for pipe welding. The magnetic base includes an end, a swing arm, and a fixed base connected in sequence. The fixed base has an arc-shaped structure, and the swing arm is connected to it at an angle parallel to its axis. One or more strong magnets are provided at the straight edge of the arc-shaped structure. The end is also connected in sequence to a wire and a connector, with the wire fixed to the fixed base. This patent provides a magnetic base for pipe welding that solves the technical problem of difficulty in fixing pipe welding clamps in existing technologies. However, although this device solves the above problem, it still has the drawback of difficulty in cleaning welding slag and the inside of the device. Therefore, a tubular metal welding fixing device is proposed to solve the aforementioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a tubular metal welding and fixing device to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a tubular metal welding and fixing device, comprising a body, a motor disposed at the front of the body, a welding device disposed inside the body, a clamping device disposed at the output end of the motor, a dust removal mechanism disposed on the inner wall of the bottom of the body, an observation window disposed on the left side of the body, and a cleaning structure disposed on the inner wall of the body. The clamping device includes a protrusion, a clamp, a return spring, a clamping plate, a limiting ring, a fixing clamp, and a fixing ring. The protrusion is disposed at the output end of the motor, the fixing ring is disposed at the front of the protrusion, the clamp is disposed on the inner wall of the protrusion, the clamping plate is slidably connected to the outer surface of the clamp, the limiting ring is fixedly connected to the left side of the fixing ring, and the return spring... One end is fixedly connected to the bottom of the clamp, and the other end of the return spring is fixedly connected to the outer wall of the clamping plate. The limiting ring is fixedly connected to the left side of the fixed ring. The fixed clamp is rotatably connected to the inner wall of the limiting ring through a torsion spring. There are three clamps, and the three clamps are arranged in a circular array on the inner wall of the fixed ring. When the clamp slides on the inner surface of the fixed ring to clamp the workpiece, the clamps converge and drive the clamping plate to move through the reciprocating spring, so that the clamping plate contacts the workpiece and clamps it. At the same time, when the clamp moves, it will contact the fixed clamp and push it to rotate. The fixed clamp will rotate around the limiting ring as the center and expand its other end outward, so that the fixed clamp expands on the inner wall of the container and limits and locks the inside of the container, further improving its fixing effect.

[0006] Preferably, the dust-sweeping mechanism includes a vertical plate, a second reset spring, a limiting groove, a drive wheel, a top brush, a fourth reset spring, and a bottom brush. The limiting groove is formed on the inner wall of the machine body. The vertical plate is slidably connected to the inner wall of the limiting groove. The top brush is slidably connected to the right side of the vertical plate. The drive wheel is rotatably connected to the top of the top brush. The bottom brush is fixedly connected to the right side of the vertical plate. One end of the fourth reset spring is fixedly connected to the bottom of the top brush, and the other end is fixedly connected to the top of the bottom brush. One end of the second reset spring is fixedly connected to the bottom of the vertical plate, and the other end is fixedly connected to the inner wall of the machine body. The drive wheel is in contact with the welded parts. Brush bristles are fixedly connected to the bottom of the bottom brush, and a brush is fixedly connected to the top of the top brush. The bristles of the bottom brush contact the inner wall of the machine body, the protrusion contacts the vertical plate during movement, and the bristles of the top brush contact the welded parts. The device first runs idle, and the protrusion is driven to rotate by the motor. After the protrusion rotates, it contacts the vertical plate and pushes it to move. The vertical plate drives the top brush to move. The movement of the top brush can clean the dust and impurities on the surface of the workpiece, preventing the presence of impurities from affecting the welding effect during the welding process. At the same time, the reset spring three on the top of the bottom brush supports the bottom brush, so that the drive wheel on the top of the top brush contacts the workpiece. When cleaning workpieces of different diameters, the drive wheel will push the top brush to compress the reset spring three along the arc surface of the workpiece, thus making it suitable for workpieces of different diameters.

[0007] Preferably, the cleaning mechanism includes a reciprocating screw, a lever, a return spring, a drive plate, a scraper, a vertical limiting groove, a collection chamber, an upper guide plate, a lower guide plate, and a drive wheel. The vertical limiting groove is fixedly connected to the inner wall of the machine body. The scraper is slidably connected to the inner wall of the vertical limiting groove. The drive plate is fixedly connected to the rear of the scraper. The collection chamber is fixedly connected to the bottom of the scraper. The reciprocating screw is rotatably connected to the inner wall of the collection chamber. The drive wheel is fixedly connected to the right side of the reciprocating screw. The lever is slidably connected to the outer circumferential surface of the reciprocating screw. The upper guide plate is fixedly connected to the inner wall of the collection chamber. The lower guide plate is fixedly connected to the inner wall of the collection chamber. The lever is slidably connected to the outer circumferential surface of the reciprocating screw. The upper guide plate is fixedly connected to the inner wall of the collection chamber. The lower guide plate is fixedly connected to the inner wall of the collection chamber. The fixing rod is fixedly connected to the bottom of the collection chamber. The lever is slidably connected to the outer circumference of the fixed rod. One end of the return spring is fixedly connected to the bottom of the vertical limiting groove, and the other end is fixedly connected to the top of the scraper rod. When the welding is finished, there is a lot of dust in the observation window. At this time, the motor is started and reversed. During the rotation of the protrusion, the drive plate will move downward and drive the scraper rod to move. Then the return spring will reset and scrape the dust off the inner wall of the observation window to keep the observation window clean. At the same time, the dust scraped off by the scraper rod will slide down into the bottom collection chamber through the upper guide plate and the lower guide plate. While the scraper rod moves up and down, the drive wheel will rub against the machine body to make the drive wheel rotate, thereby driving the reciprocating screw to rotate and making the lever move. Under the restriction of the fixed rod, the lever will move back and forth on the circumference of the reciprocating screw. While the lever moves back and forth, it will spread the dust inside the collection chamber to prevent the dust from accumulating too high in one place and causing leakage.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This tubular metal welding and fixing device, through the interaction of the fixing ring, clamp, and fixing clamp, activates the fixing ring to bring the clamp towards the center to clamp the workpiece. At the same time, when the clamp moves, it drives the fixing clamp to move, causing the fixing clamp to open outward to fix the inner wall of the tubular workpiece, thereby achieving a better clamping effect.

[0010] 2. This tubular metal welding and fixing device, with the cooperation of the top brush, bottom brush, and return spring 2, has the top brush contacting the workpiece during the welding process. When the workpiece rotates, its outer circumference will contact the top brush, thus cleaning the surface of the workpiece and removing the welding slag. During the back-and-forth motion, the bottom brush will sweep away the welding dust at the bottom of the machine body, preventing excessive dust accumulation inside the machine body. When the workpiece size is different, the height of the top brush can be adjusted by squeezing the return spring 3 to adapt to workpieces of various sizes.

[0011] 3. In this tubular metal welding and fixing device, with the cooperation of the scraper rod, collection chamber, upper guide plate, lower guide plate, drive wheel, reciprocating screw, lever, and fixing rod, the dust scraped off by the scraper rod will slide down into the bottom collection chamber through the upper and lower guide plates. While the scraper rod moves up and down, the drive wheel will rub against the machine body to rotate, thereby driving the reciprocating screw to rotate and causing the lever to move. Under the restriction of the fixing rod, the lever will move back and forth on the circumferential surface of the reciprocating screw. While the lever moves back and forth, it will level the dust inside the collection chamber to prevent the dust from accumulating too high in one place and causing leakage.

The limiting ring 405 is fixedly connected to the left side of the fixing ring 407. One end of the reset spring 403 is fixedly connected to the bottom of the clamp 402, and the other end of the reset spring 403 is fixedly connected to the outer wall of the clamping plate 404. The limiting ring 405 is fixedly connected to the left side of the fixing ring 407. The fixing clamp 406 is rotatably connected to the inner wall of the limiting ring 405 through a torsion spring. There are three clamps 402, and the three clamps 402 are distributed in a circular array on the inner wall of the fixing ring 407. The clamps 402 are slidably connected to the inner surface of the fixing ring 407.

[0022] The dust removal mechanism 7 includes a vertical plate 701, a second return spring 702, a limiting groove 703, a drive wheel 704, a top brush 705, a fourth return spring 706, and a bottom brush 707. The limiting groove 703 is formed on the inner wall of the body 1. The vertical plate 701 is slidably connected to the inner wall of the limiting groove 703. The top brush 705 is slidably connected to the right side of the vertical plate 701. The drive wheel 704 is rotatably connected to the top of the top brush 705. The bottom brush 707 is fixedly connected to the right side of the vertical plate 701. One end of the fourth return spring 706 is fixedly connected to the top brush 705. At the bottom, the other end of the reset spring 706 is fixedly connected to the top of the bottom brush 707, one end of the reset spring 702 is fixedly connected to the bottom of the vertical plate 701, and the other end of the reset spring 702 is fixedly connected to the inner wall of the body 1.

The protrusion 401 is in contact with the vertical plate 701 during movement, and the brush bristles of the top brush 705 are in contact with the welded part.

[0023] Working principle: When clamping a workpiece, the clamp 402 closes and drives the clamping plate 404 to move through the return spring 403, so that the clamping plate 404 contacts the workpiece and clamps it. At the same time, when the clamp 402 moves, it will contact the fixing clamp 406 and push it to rotate. The fixing clamp 406 will rotate around the limiting ring 405 as the center and expand its other end outward, so that the fixing clamp 406 expands on the inner wall of the container and limits and locks the inside of the container, further improving its fixing effect.

[0024] Before welding, the device is run dry. The protrusion 401 is rotated by the motor 2. After rotating, the protrusion 401 will contact the vertical plate 701 and push it to move. The vertical plate 701 drives the top brush 705 to move. The movement of the top brush 705 can clean the dust and impurities on the surface of the workpiece, preventing the presence of impurities from affecting the welding effect. At the same time, the return spring 706 at the top of the bottom brush 707 will support the bottom brush 707, so that the drive wheel 704 at the top of the top brush 705 will contact the workpiece. When cleaning workpieces of different diameters, the drive wheel 704 will push the top brush 705 along the arc surface of the workpiece to compress the return spring 706, thus making it suitable for workpieces of different diameters.

[0025] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the cleaning mechanism 6 includes a reciprocating screw 601, a lever 602, a return spring 603, a drive plate 604, a scraper 605, a vertical limiting groove 606, a collection chamber 607, an upper guide plate 608, a lower guide plate 609, and a drive wheel 610.

The upper guide plate 608 is in contact with the inner wall of the observation window 5, and the scraper rod 605 is in contact with the inner wall of the observation window 5.

[0026] Working principle: When welding is finished, there is a lot of dust in the observation window 5. At this time, the motor 2 is started and reversed. During the rotation of the protrusion 401, the drive plate 604 will move downward and drive the scraper rod 605 to move. Then, the return spring 603 will reset and scrape the dust off the inner wall of the observation window 5 to keep the observation window 5 clean. At the same time, the dust scraped off by the scraper rod 605 will slide down through the upper guide plate 608 and the lower guide plate 609 into the bottom collection chamber 607. While the scraper rod 605 moves up and down, the drive wheel 704 will rub against the machine body 1 to make the drive wheel 610 rotate, which will drive the reciprocating screw 601 to rotate and make the lever 602 move. Under the restriction of the fixed rod 611, the lever 602 will move back and forth on the circumferential surface of the reciprocating screw 601. While the lever 602 moves back and forth, it will spread the dust inside the collection chamber 607 to prevent the dust from accumulating too high in one place and causing leakage.
