Description

Technical Field

[0001] The present invention relates to the field of welding technology, and particularly to a welding device for metal components. Background Art

[0002] Metal components refer to parts or components made of various metals used in fields such as construction, machinery, and electronics. These components can be of various shapes and sizes and are usually manufactured according to specific design requirements and functional needs. In the construction field, metal components can be used for support structures, exterior wall decoration, roof covering, door and window frames, etc. Common metal components include steel beams, steel columns, steel pipes, steel plates, etc. They usually have the characteristics of high strength, corrosion resistance, and stability, and can withstand large loads and environmental impacts.

[0003] When traditionally welding metal components, the method of welding the external connection parts is often used. However, there is a lack of support inside the connection parts of the metal components, and problems such as deformation and shrinkage are likely to occur due to the heat generated during welding, which will affect the quality of the metal components after connection.

[0004] To solve the above problems, we propose a welding device for metal components. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the background art, and a welding device for metal components is proposed.

The end of the base is fixedly connected with a guide plate. A slide plate is slidably sleeved at the end of the guide plate. The end of the guide plate is fixedly connected with an oil cylinder. The driving end of the oil cylinder is fixedly connected with the inner wall of the slide plate. Clamping mechanisms are provided on both the base and the slide plate. The upper side wall of the guide plate is fixedly connected with an annular guide rail. An electric trolley is slidably arranged in the annular guide rail. A welding assembly is arranged on the electric trolley;

[0007] A motor is fixedly connected to the outer wall of the base. The driving end of the motor is fixedly connected with a second telescopic rod. The end of the second telescopic rod is fixedly connected with a connecting pipe. The end of the connecting pipe is fixedly connected with a piston pipe. A piston rod is slidably inserted into the end of the piston pipe. The upper end of the piston rod is fixedly connected with a heat conducting plate. A return spring is fixedly connected between the heat conducting plate and the piston pipe. A water inlet pipe and a water outlet pipe are arranged in the connecting pipe. An extension groove is opened on the inner wall of the piston pipe. A heat conducting cavity is opened inside the piston rod. An inlet and an outlet communicating with the heat conducting cavity are opened on the outer wall of the piston rod. The outlet is connected with the water outlet pipe through a hose.

[0008] In the above-mentioned metal component welding device, the welding assembly includes a first telescopic rod fixedly connected to the outer wall of the electric trolley, and a welding gun head is fixedly connected to the end of the first telescopic rod.

[0009] In the above-mentioned metal component welding device, the clamping mechanism includes a support seat fixedly connected to the base and the sliding plate. A circular ring is fixedly connected to the upper end of the support seat. An annular groove is formed on the outer wall of the circular ring. A gear ring is sleeved in the annular groove. A motor is fixedly connected to the outer wall of the support seat. A gear column meshing with the gear ring is fixedly connected to the driving end of the motor. A plurality of through holes are formed in the circular ring. A moving column is slidably inserted into the through hole. A rotating plate located inside the moving column is rotatably connected to the inner wall of the circular ring. A clamping plate is rotatably connected to the end of the rotating plate. A telescopic spring is sleeved on the outer wall of the moving column. Two ends of the telescopic spring are respectively fixedly connected to the outer wall of the moving column and the inner wall of the circular ring. An inclined surface located outside the end of the moving column is formed on the inner wall of the gear ring. The end of the moving column is in contact with the inclined surface.

[0010] In the above-mentioned metal component welding device, a cross plate is fixedly connected to the outer wall of the base. A power supply ring sleeved on the outer wall of the second telescopic rod is fixed on the cross plate. A carbon brush in contact with the power supply ring is fixedly connected to the outer wall of the second telescopic rod.

[0011] In the above-mentioned metal component welding device, a first hollow disc and a second hollow disc are fixedly connected to the upper side wall of the cross plate. A water replenishing pipe and a drain pipe are respectively arranged on the outer walls of the first hollow disc and the second hollow disc. Sealing bearings are arranged at the centers of the two outer side walls of the first hollow disc and the second hollow disc. A connecting pipe is fixedly connected to the inner ring of the sealing bearing. A water inlet communicating with the water inlet pipe and located inside the first hollow disc is formed on the outer wall of the connecting pipe. A liquid discharge port communicating with the water outlet pipe and located inside the second hollow disc is formed on the outer wall of the connecting pipe.

[0012] In the above-mentioned metal component welding device, both the upper and lower ends of the moving column are semicircularly arranged.

[0013] In the above-mentioned metal component welding device, each clamping plate 12 is arc-shaped.

[0014] Compared with the existing technology, the advantages of this metal component welding device are as follows:

[0015] A clamping mechanism is set up. The metal components to be welded are respectively placed into the two clamping mechanisms. The motor is started to drive the gear column to rotate. The rotation of the gear column drives the gear ring to rotate through the meshing of the gear column and the gear ring. After the gear ring rotates a certain amplitude, the inclined plane in contact with the outer end of the moving column moves from the middle to the end, and then the moving column will be extruded to move towards the center side of the ring, pushing the end of the rotating plate to rotate inwards, so that the clamping plate contacts and presses against the outer wall of the metal component, completing the fixation of the metal component and ensuring the stability during the welding of the metal component;

[0016] An annular guide rail is set up. The electric trolley moves along the annular guide rail. The driving end of the first telescopic rod extends out, so that the welding gun head contacts the joint of the metal component. The welding gun head welds the joint of the metal component. As the electric trolley moves, the welding work of the entire joint of the metal component can be completed, and the welding work of non-circular metal components can be adapted through the expansion and contraction of the driving end of the first telescopic rod;

[0017] A heat conduction plate is set up. The external liquid pump is connected to the water replenishing pipe, and the external water source is pumped into the water inlet pipe and flows into the piston pipe through the water inlet pipe. First, the piston rod is pushed upwards until the heat conduction plate contacts the inner wall of the joint of the metal component. After the piston rod moves upwards until the water inlet is communicated with the extension groove, at this time, the water flows through the extension groove into the water inlet, flows inside the heat conduction cavity to adsorb heat, and then flows out from the water outlet into the water outlet pipe;

[0018] In the present invention, after the metal component is clamped and moved close to and contacted, the welding work is completed by driving the welding gun head to move through the electric trolley. During the welding, the heat conduction plate rotates to the inner side of the welding position, supports and conducts out the welding heat, accelerating the welding shaping and avoiding the problem of overheating and collapse of the metal component during welding.

Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Refer to Figures 1 - 4 , a metal component welding device, including a base 1, the end of the base 1 is fixedly connected with a guide plate 2, the end of the guide plate 2 is slidably sleeved with a sliding plate 3, the end of the guide plate 2 is fixedly connected with an oil cylinder, and the driving end of the oil cylinder is fixedly connected with the inner wall of the sliding plate 3. Clamping mechanisms are provided on both the base 1 and the sliding plate 3. The clamping mechanism includes a support seat 14 fixedly connected to the base 1 and the sliding plate 3. The upper end of the support seat 14 is fixedly connected with a circular ring 7. An annular groove is opened on the outer wall of the circular ring 7. A gear ring 8 is sleeved in the annular groove. A motor 16 is fixedly connected to the outer wall of the support seat 14. The driving end of the motor 16 is fixedly connected with a gear column 15 meshing with the gear ring 8. A plurality of through holes are opened on the circular ring 7. A moving column 9 is slidably inserted in the through holes. A rotating plate 11 located inside the moving column 9 is rotatably connected to the inner wall of the circular ring 7. The end of the rotating plate 11 is rotatably connected with a clamping plate 12. Each clamping plate 12 is arc-shaped. A telescopic spring 13 is sleeved on the outer wall of the moving column 9. The two ends of the telescopic spring 13 are respectively fixedly connected with the outer wall of the moving column 9 and the inner wall of the circular ring 7. An inclined surface 10 located outside the end of the moving column 9 is opened on the inner wall of the gear ring 8. The end of the moving column 9 is in contact with the inclined surface 10. The upper and lower ends of the moving column 9 are both semicircular. The semicircular setting ensures the smoothness of the contact between the moving column 9 and the inclined surface 10 and the rotating plate 11, and avoids the phenomenon of the moving column 9 being stuck.

[0026] The driving end of the oil cylinder extends, and the metal components to be welded are respectively placed into the two clamping mechanisms. The motor 16 is started to drive the gear column 15 to rotate. The rotation of the gear column 15 drives the gear ring 8 to rotate through the meshing of the gear column 15 and the gear ring 8. After the gear ring 8 rotates a certain amplitude, the inclined surface 10 moves from the middle to the end and abuts against the moving column 9, and then the moving column 9 will be extruded to move towards the center side of the ring 7, pushing the end of the rotating plate 11 to rotate inwards, so that the clamping plate 12 contacts and presses against the outer wall of the metal component, completing the fixation of the metal component. Moreover, multiple clamping plates 12 move towards the center of the ring 7 together, enabling the center of the metal component to coincide with the center of the ring 7, ensuring the centering of the metal component after clamping;

[0027] After the metal component is stably clamped, the driving end of the oil cylinder retracts, making the ends of the two metal components contact each other. At this time, the welding work of the two metal components can be carried out.

[0028] The upper side wall of the guide plate 2 is fixedly connected with an annular guide rail 4. An electric trolley is slidably arranged in the annular guide rail 4. A welding assembly 5 is arranged on the electric trolley. The welding assembly 5 includes a telescopic rod I fixedly connected to the outer wall of the electric trolley. The end of the telescopic rod I is fixedly connected with a welding torch head. The electric trolley moves along the annular guide rail 4. The driving end of the telescopic rod I extends, making the welding torch head contact the connection part of the metal component. The welding torch head welds the connection part of the metal component. As the electric trolley moves, the welding work of the entire connection part of the metal component can be completed. When the metal component is non-circular, the welding work at different positions can also be realized by the telescopic movement of the end of the telescopic rod I. When the metal component is circular, after the driving end of the telescopic rod I extends and the welding torch head contacts the metal component, no further adjustment is required subsequently;

[0029] Whether the welding torch head end contacts the metal component can be measured by setting an ultrasonic sensor on the electric trolley to measure the distance;

[0030] A motor 17 is fixedly connected to the outer wall of the base 1. The driving end of the motor 17 is fixedly connected to a second telescopic rod 18. The end of the second telescopic rod 18 is fixedly connected to a connecting pipe 23. The end of the connecting pipe 23 is fixedly connected to a piston pipe 24. A piston rod 25 is slidably inserted into the end of the piston pipe 24. The upper end of the piston rod 25 is fixedly connected to a heat conducting plate 27. A return spring 26 is fixedly connected between the heat conducting plate 27 and the piston pipe 24. An inlet pipe 29 and an outlet pipe 30 are arranged in the connecting pipe 23. An extension groove 6 is formed in the inner wall of the piston pipe 24. A heat conducting cavity is formed in the piston rod 25. An inlet and an outlet communicating with the heat conducting cavity are formed in the outer wall of the piston rod 25. The outlet is connected to the outlet pipe 30 through a hose. A hollow disc one 19 and a hollow disc two 20 are fixedly connected to the upper side wall of the cross plate 28. A water replenishing pipe 21 and a drain pipe are respectively arranged on the outer walls of the hollow disc one 19 and the hollow disc two 20. Sealing bearings are arranged at the centers of the outer walls on both sides of the hollow disc one 19 and the hollow disc two 20. The connecting pipe 23 is fixedly connected to the inner ring of the sealing bearing. An inlet communicating with the inlet pipe 29 and located inside the hollow disc one 19 is formed in the outer wall of the connecting pipe 23. A liquid discharge port communicating with the outlet pipe 30 and located inside the hollow disc two 20 is formed in the outer wall of the connecting pipe 23. During the welding process, in order to prevent the inner side of the welded joint of the metal component from collapsing, the driving end of the second telescopic rod 18 extends out to move the heat conducting plate 27 to the contact position of the metal component. An external liquid pump is connected to the water replenishing pipe 21 to pump external water source into the inlet pipe 29, and it flows into the piston pipe 24 through the inlet pipe 29, first pushing the piston rod 25 upwards until the inner wall of the connection position between the heat conducting plate 27 and the metal component is contacted. Because of the limited water pressure, it cannot be pushed upwards all the time. After the piston rod 25 moves upwards until the inlet communicates with the extension groove 6, at this time, the water flow discharges into the inlet through the extension groove 6, flows inside the heat conducting cavity to adsorb heat, and then flows out from the outlet to the outlet pipe 30. On the one hand, the heat conducting plate 27 can form a support inside the welded joint of the metal component, avoiding the problem of collapse of the welded part caused by high temperature. On the other hand, the heat conducting plate 27 and the piston rod 25 can conduct the heat of the welded joint, enabling the welded joint to be quickly shaped and further avoiding the problem of collapse;

[0031] Furthermore, both the piston rod 25 and the heat conducting plate 27 are made of heat conducting materials.

[0032] A cross plate 28 is fixedly connected to the outer wall of the base 1. A power supply ring 22 sleeved on the outer wall of the second telescopic rod 18 is fixed on the cross plate 28. A carbon brush in contact with the power supply ring 22 is fixedly connected to the outer wall of the second telescopic rod 18. During the process of the motor 17 driving the second telescopic rod 18 to rotate, the carbon brush is always in contact with the power supply ring 22 to achieve uninterrupted power supply.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
