Description

Technical Field

[0001] The invention belongs to the technical field of electric welding equipment, and more specifically, particularly relates to a small metal pipe electric welding equipment used in metal processing plants. Background Art

[0002] In the field of welding small metal pipes, traditional welding methods have many problems.

[0003] In the past, welding operations often relied on manual positioning and clamping, which made it difficult to ensure that small metal pipes did not shift in position during welding, affecting the quality and firmness of the welding.

[0004] Cleaning small metal pipes before welding is usually cumbersome and ineffective. Since it is difficult to clean the inner and outer surfaces of small metal pipes, impurities such as oil and rust can easily affect the bonding strength of the weld, but existing cleaning methods are difficult to effectively solve this problem.

[0005] Moreover, traditional welding equipment has a single function, and the welding and cleaning processes are separated, which not only increases the operation steps and time, but also takes up a large space. During the welding process, the rotation and movement control of small metal pipes is not precise and automated enough, resulting in low welding efficiency and failure to achieve uniform welding throughout the circle.

[0006] At the same time, the resetting of the equipment also mostly relies on manual operation, which is time-consuming and labor-intensive, reducing the efficiency of each work.

[0007] In summary, the existing small metal pipe welding equipment has shortcomings in positioning and clamping, cleaning effect, degree of integration, level of automation and reset operation. A more efficient, precise, automated and integrated welding equipment is needed to solve these problems. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a small metal pipe electric welding equipment for metal processing plants to solve the above problems.

[0010] Preferably, the two L-shaped rails are symmetrically distributed on the surface of the support plate with the welding machine assembly as the center point, and a first drive assembly is arranged inside the vertical sections of the two L-shaped rails. A limit plate is fixedly installed on the inner side wall of each first drive assembly near the bottom of the vertical section, and a pressure switch is fixedly installed on the inner wall at the end of the horizontal section of each L-shaped rail. A semicircular thread groove is opened on the side wall of each side slide frame, and the semicircular thread groove is used to cooperate with the threaded rod of the first drive assembly. A protrusion is fixedly installed on the top of each support box, and a first motor is fixedly installed on the inner wall at the end of each fixed frame, and the output end of each first motor is fixedly connected to the first threaded rod.

[0011] Preferably, the back side of the pushing frame is located in the topmost fixed frame, and the back side of the clamping frame is located in the lower fixed frame. A separation sleeve is fixedly mounted on the surface of the middle part of each first threaded rod, and each first threaded rod has opposite threads at both ends with the separation sleeve as the center point. A rotating shaft is fixedly installed at the bottom of each pushing frame, and a lower push plate is rotatably mounted on the surface of each rotating shaft. Inclined plates are fixedly mounted on the side walls of the two pushing frames facing each other, and a spring is fixedly mounted between the side wall of each lower push plate and the side wall of the inclined plate.

[0012] Preferably, a second driving assembly is provided inside each of the clamping frames, and the ends of the threaded rods in each of the second driving assemblies are rotatably connected to the inner wall of the clamping frame, and the threads at both ends of each of the second driving assemblies are opposite with the middle as the boundary, and the tops of the two clamping rods are arranged outside the second driving assembly through threaded sleeves, and a second motor is fixedly installed inside each of the support boxes, and the ends of the output shafts of each of the second motors are fixedly connected to the back side of the cleaning roller sleeve, and an inner bracket is fixedly installed on the inner wall of the side end of each of the cleaning roller sleeves, and at least two cleaning cottons and a metal cleaning brush are fixedly installed on the surface of each of the inner brackets, and the metal cleaning brushes are inserted into the cleaning cotton, and the height of each of the metal cleaning brushes is lower than the cleaning cotton.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the support box contacts the pressure switch to start the first drive component, at which time the threaded rod of the first drive component rotates to drive the support box to move downward, while the push frame and the clamping frame continue to move, and when the ends of the two small metal tubes are fitted together, it stops, and every two clamping rods move backward a micro distance to loosen the small metal tube. At this time, the electric welder component on the surface of the support plate welds the interface of the two small metal tubes, and at the same time, the rotating drive component above the sliding frame rotates to drive the small metal tube to rotate, and the small metal tube completes a circle of electric welding. Before the small metal tube is welded, the inner and outer welding joints of the small metal tube are cleaned by using a cleaning roller sleeve, so as to ensure the firmness of the small metal tube after welding. At the same time, two clamping frames are used at the same time to ensure that the positions of the two small metal tubes will not be offset during welding, and the rotating drive component is used to rotate the small metal tube to ensure that the small metal tube can be welded a full circle.

[0014] In the present invention, when the two clamping frames clamp the small metal pipe, the motor at the end of the second driving component drives the two clamping rods to approach each other through the threaded rod and clamp the small metal pipe. The two clamping rods are both V-shaped, fixing small metal pipes of different sizes, and at the same time ensuring that the small metal pipe is located at the center point after being fixed, so that the clamping rod can insert the small metal pipe into the cleaning roller sleeve, and the cleaning cotton on the inner wall of the cleaning roller sleeve and the surface of the pushing frame is longer, so that it can cooperate with the clamping rod to adapt to small metal pipes of different diameters, thereby improving the cleaning ability of the small metal pipe before welding.

[0015] In the present invention, the rotation of the cleaning roller sleeve drives the internal inner bracket to rotate synchronously, and the rotation of the inner bracket drives the cleaning cotton and the metal cleaning brush on the surface to rotate. The inner wall of the cleaning roller sleeve scrapes and cleans the surface of the small metal tube, and the cleaning cotton and the metal cleaning brush on the surface of the inner bracket can clean the inner wall of the small metal tube, and the two cleaning tools can achieve better cleaning effects. The cleaning operation of the inner and outer surfaces of small metal tubes is relatively difficult. If there are impurities such as oil, rust, etc., it will affect the bonding strength of the welding. The device effectively solves the cleaning problem of small metal tubes.

[0016] In the present invention, the two small metal tubes are slightly loosened to keep the positions of the two small metal tubes unchanged, but can be driven to rotate by the rotating drive assembly, and the electric welder assembly welds the two small metal tubes in a full circle. After welding is completed, the four clamping rods under the two clamping frames loosen the small metal tubes, and the two small metal tubes are driven forward by the rotating drive assembly, and the two small metal tubes fall along the sliding frame. By designing the rotating drive assembly to drive the small metal tubes to rotate and weld, it can also help the small metal tubes fall after welding, thereby greatly improving the overall automation and the welding capacity.

[0017] In the present invention, the fixing frame at the top is started first to drive the pushing frame to move toward the front side of the supporting box through the first threaded rod. When the push plate moves and contacts the protrusion, it will drive the supporting box to move toward the side of the small metal tube. When the cleaning roller sleeve at the end of the supporting box is docked with the small metal tube, the force of the spring is not enough to support the push plate. At this time, the push plate rotates. At this time, the pushing frame will drive the push plate to cross the protrusion and move to the front side of the supporting box, and the cleaning roller sleeve and the small metal tube will be automatically docked, thereby reducing the difficulty of manual docking and increasing the speed of docking.

[0018] In the present invention, the side sliding frame drives the supporting box to move downward as a whole, and at this time the pushing frame can continue to move toward one side of the electric welder assembly, and the supporting box stops when it moves downward to the limit plate, and the two clamping frames drive the small metal pipe to dock and then stop. By utilizing the cooperation between the pushing frame and the supporting box, and then utilizing the shape of the L-shaped slide rail, the supporting box can be moved laterally to leave the small metal pipe, and avoid the clamping frame when moving downward, thereby ensuring that the small metal pipe is not blocked when moving, and the overall linkage ability is strong, so that the small metal pipe does not need to be cleaned separately using a cleaning mechanism before welding, which greatly shortens the welding time, integrates cleaning and welding, reduces the overall space of the equipment, and improves the welding efficiency.

[0019] In the present invention, when the welding of the small metal pipe is completed and the equipment needs to be reset, the two clamping frames are preferentially moved and reset to the end of the fixed frame, and then the support box moves upward to the horizontal section of the L-shaped slide rail. At this time, the push frame moves and drives the support box to move and reset through the push-down plate. The overall automation is strong, and the next welding operation is convenient after resetting, which greatly improves the work efficiency each time, and there is no need to manually reset the equipment.

[0027] Working principle: In the first step, when the user performs electric welding on the two small metal tubes 13, the user puts the two small metal tubes 13 under the two fixing frames 14 respectively, and each two first threaded rods 16 clamp the small metal tubes 13, and then the first motor 15 operates to drive the push frame 28 to move through the first threaded rod 16, and the push frame 28 moves to drive the support box 33 to move close to the small metal tube 13. When the cleaning roller sleeve 36 is sleeved outside the support box 33, the push frame 28 continues to move, driving the lower push plate 31 below to rotate over the support box 33 and move to the other side of the support box 33, and start the second motor 37. At this time, the cleaning roller sleeve 36 and the internal inner bracket 38 clean the inner and outer walls of the small metal tube 13, and then the first motor 15 located at the top is started to drive the push frame 28 to move through the first threaded rod 16, and the push frame 28 moves through the lower push plate 31 to drive the support box 33 to move (the elastic force of the spring 32 can maintain the thrust of the lower push plate 31 on the support box 33). When the movement reaches the end of the L-shaped slide rail 2, the support box 33 is connected The pressure switch 22 is touched to start the first drive assembly 21. At this time, the threaded rod of the first drive assembly 21 rotates to drive the support box 33 to move downward, and the push frame 28 and the clamping frame 24 continue to move. When the ends of the two small metal tubes 13 are fitted, they stop. Every two clamping rods 26 move backward a micro distance to loosen the small metal tube 13. At this time, the electric welder assembly 19 on the surface of the support plate 18 welds the interface of the two small metal tubes 13. At the same time, the rotation drive assembly 42 above the sliding frame 12 rotates to drive the small metal tube 13 to rotate, and the small metal tube 13 completes a circle of electric welding. Before the small metal tube 13 is welded, the inner and outer welding ports of the small metal tube 13 are cleaned by using a cleaning roller sleeve 36, so as to ensure that the small metal tube 13 is firmly welded. At the same time, two clamping frames 24 are used at the same time to ensure that the positions of the two small metal tubes 13 during welding will not be offset. The rotation drive assembly 42 is used to rotate the small metal tube 13 to ensure that the small metal tube 13 can be welded in a full circle.

[0028] In the second step, when the two clamping frames 24 clamp the small metal tube 13, the motor at the end of the second driving assembly 25 drives the two clamping rods 26 to approach each other through the threaded rod and clamp the small metal tube 13. The two clamping rods 26 are both V-shaped, fixing small metal tubes 13 of different sizes, and can ensure that the small metal tube 13 is located at the center point after being fixed, so that the clamping rods 26 can insert the small metal tube 13 into the cleaning roller sleeve 36, and the cleaning cotton 39 on the inner wall of the cleaning roller sleeve 36 and the surface of the pushing frame 28 is relatively long, so that the clamping rods 26 can be used to adapt to small metal tubes 13 of different diameters, thereby improving the cleaning ability of small metal tubes before welding; After the cleaning roller sleeve 36 is sleeved on the outside of the small metal tube 13, the second motor 37 is started to drive the cleaning roller sleeve 36 to rotate, and the rotation of the cleaning roller sleeve 36 drives the internal inner bracket 38 to rotate synchronously, and the rotation of the inner bracket 38 drives the cleaning cotton 39 and the metal cleaning brush 4 on the surface to rotate, and the inner wall of the cleaning roller sleeve 36 scrapes and cleans the surface of the small metal tube 13, and the cleaning cotton 39 and the metal cleaning brush 4 on the surface of the inner bracket 38 can clean the inner wall of the small metal tube 13, and the two cleaning tools can achieve a better cleaning effect. The cleaning operation of the inner and outer surfaces of the small metal tube 13 is relatively difficult. If there are impurities such as oil, rust, etc., it will affect the bonding strength of the welding. The device effectively solves the cleaning problem of the small metal tube 13; After the two clamping frames 24 drive the two small metal tubes 13 to move and dock, the two small metal tubes 13 are slightly loosened to keep the positions of the two small metal tubes 13 unchanged, but can be driven to rotate by the rotating drive assembly 42, and the electric welder assembly 19 welds the two small metal tubes 13 in a full circle. After welding is completed, the four clamping rods 26 under the two clamping frames 24 release the small metal tubes 13, and the two small metal tubes 13 are driven forward by the rotating drive assembly 42, and the two small metal tubes 13 fall along the sliding frame 12. By designing the rotating drive assembly 42 to drive the small metal tubes 13 to rotate and weld, it can also help the small metal tubes 13 fall after welding, thereby greatly improving the overall automation and the welding capability.

[0029] In the third step, the position relationship of the device in the initial state is: the two clamping frames 24 clamp the small metal tube 13, and the pushing frame 28 is located at the rear side of the support box 33 (close to the side of the electric welder assembly 19); the operation logic after startup is: the fixing frame 14 located at the top is started first to drive the pushing frame 28 to move toward the front side of the support box 33 through the first threaded rod 16, and when the push plate 31 moves to contact the protrusion 35, it will drive the support box 33 to move toward the side of the small metal tube 13, and when the cleaning roller sleeve 36 at the end of the support box 33 is docked with the small metal tube 13, the force of the spring 32 is not enough to support the push plate 31, and the push plate 31 rotates at this time. At this time, the pushing frame 28 will drive the push plate 31 to cross the protrusion 35 and move to the front side of the support box 33, and automatically dock the cleaning roller sleeve 36 and the small metal tube 13, thereby reducing the difficulty of manual docking and improving the docking speed; After the small metal tube 13 is cleaned, the fixing frame 14 at the top is started again, and the pushing frame 28 is driven to move backward through the first threaded rod 16. The pushing frame 28 moves backward to drive the support box 33 to move, and the support box 33 drives the side slide 34 to move inside the L-shaped slide rail 2. When the side slide 34 moves to the end of the L-shaped slide rail 2 and contacts the pressure switch 22, the pressure switch 22 starts the motor at the bottom of the first drive assembly 21. At the same time, the pressure switch 22 will start the first motor 15 behind the clamping frame 24. At this time, the first threaded rod 16 drives the clamping frame 24 to move to the side of the welder assembly 19, and the motor drives the threaded rod to rotate. At this time, the threaded rod cooperates with the semicircular thread groove 41 on the side wall of the side slide 34 to drive the side slide 34 to move downward. The frame 34 drives the support box 33 to move downward as a whole. At this time, the push frame 28 can continue to move toward the side of the electric welder assembly 19. The support box 33 stops when it moves downward to the limit plate 23. The two clamping frames 24 drive the small metal pipe 13 to dock and then stop. By utilizing the cooperation between the push frame 28 and the support box 33, and then utilizing the shape of the L-shaped slide rail 2, the support box 33 can be moved laterally away from the small metal pipe 13, and move downward to avoid the clamping frame 24, so that the small metal pipe 13 can be guaranteed to be unobstructed when moving. The overall linkage ability is strong, so that the small metal pipe 13 does not need to be cleaned by a separate cleaning mechanism before welding, which greatly shortens the welding time, integrates cleaning and welding, reduces the overall space of the equipment, and improves the welding efficiency. When the welding of the small metal tube 13 is completed and the equipment needs to be reset, the two clamping frames 24 are first moved and reset to the end of the fixed frame 14, and then the support box 33 moves upward to the horizontal section of the L-shaped slide rail 2. At this time, the push frame 28 moves through the push plate 31 to drive the support box 33 to move and reset. The overall automation is strong, and the next welding operation is convenient after resetting, which greatly improves the work efficiency each time, and there is no need to manually reset the equipment.
