Description

Technical Field

[0002] In the manufacturing process of precision instruments, welding devices may be used for a variety of instruments and equipment, especially those parts that require high precision, high strength or special materials to connect. In precision instruments, a variety of equipment may use heat dissipation pipes. The main function of these heat dissipation pipes is to help the equipment discharge the heat generated during operation, ensure the stable operation of the equipment and extend its service life. Therefore, they need to be connected together through welding devices.

[0003] For the current welding device, the existing induction welding device disclosed by patent number "CN220296098U" can use the support plate to assist the vertical side alignment when the welded part is clamped on one side by the clamping arm, so that the welded part at the upper end can maintain a precise alignment state and weld with the welded part at the lower end. However, during the welding operation, due to the different degrees of contact between the welded part and the induction coil, the side close to the coil is often subjected to more concentrated heat radiation, resulting in a significant increase in its surface temperature, while the temperature of the other side relatively far from the coil is lower, forming a significant temperature difference, causing uneven heating of the welded part surface, which affects the welding effect.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figures 1 to 6 An induction welding device for precision instrument processing includes a workbench 1, a movable plate 8 slidably connected to the surface of the workbench 1, and a support plate 33 fixed to the top surface of the workbench 1. It should be noted that a slide groove is provided on the top surface of the workbench 1 to facilitate the movement of the movable plate 8. The movable plate 8 can be guided and slid inside the slide groove. A protrusion that fits the slide groove is provided at the bottom of the movable plate 8 to facilitate the movement of the movable plate 8 along the slide groove.

[0034] The first mounting seat 12 and the second mounting seat 23 are symmetrically mounted on both sides of the top surface of the movable plate 8, and the side surfaces of the first mounting seat 12 and the second mounting seat 23 are both mounted with clamping components, which are used to clamp the heat dissipation pipe;

[0035] A welding assembly, which is installed above the workbench 1 and is used for welding the heat dissipation pipe;

[0036] A rotating assembly, which is disposed on the end side of the first mounting seat 12 and is used to drive the clamping assembly to rotate;

[0037] A polishing assembly, which is disposed above the first mounting seat 12 and is used for polishing the heat dissipation pipe;

[0038] The flux spraying assembly is disposed above the support plate 33 and is used for spraying flux on the heat dissipation pipe.

[0039] The clamping assembly includes a rotating shaft 10 rotatably connected to the inside of the first mounting seat 12 and a rotating shaft 2301 rotatably connected to the inside of the second mounting seat 23. A U-shaped plate 13 is fixed on the relatively close side of the rotating shaft 10 and the rotating shaft 2301. The upper and lower sides of the U-shaped plate 13 are fixedly connected to the first spring 14, and the end of the first spring 14 away from the U-shaped plate 13 is fixedly connected to the clamping ring 15. It should be noted that by setting the rotating shaft 10 and the rotating shaft 2301, the two ends of the heat dissipation pipe to be welded are clamped together, and the rotating shaft 10 is driven to rotate by the motor 9, thereby driving the heat dissipation pipe in front of the first mounting seat 12 to rotate. When the heat dissipation pipe rotates, it drives the heat dissipation pipe in front of the second mounting seat 23 to rotate together, thereby achieving the effect of synchronous rotation.

[0040] The welding assembly includes a support frame 2 fixed on the top surface of the workbench 1, an electric telescopic rod 3 is installed on the bottom surface of the support frame 2, a high-frequency heating power supply 4 is installed at the telescopic end of the electric telescopic rod 3, the bottom end of the high-frequency heating power supply 4 is threadedly connected with a connecting bolt 5, the interior of the high-frequency heating power supply 4 is provided with an external thread that matches the connecting thread, and a high-frequency induction coil 6 is installed at the bottom of the connecting bolt 5.

[0041] The rotating assembly includes a motor 9 fixedly connected to the top surface of the moving plate 8, the output end of the motor 9 is fixedly connected to the rotating shaft 10, the grinding assembly includes a first gear 11 fixedly connected to the rotating shaft 10 and a one-way bearing 17 rotatably connected to the side wall of the first mounting seat 12, the outer portion of the one-way bearing 17 is fixedly sleeved with a second gear 16, the first gear 11 and the second gear 16 are meshed with each other, the upper end of the first mounting seat 12 is provided with a through groove 1201, the inner wall of the through groove 1201 is rotatably connected with a reciprocating screw 18, the reciprocating screw 18 is threadedly connected with a screw nut 19, the reciprocating screw 18 is fixedly connected to the one-way bearing 17, the upper surface of the screw nut 19 is fixedly connected with a connecting plate 20, the bottom surface of the connecting plate 20 is installed with a second hydraulic rod 21, the output end of the second hydraulic rod 21 is fixedly connected with a grinding ring 22, the grinding ring 22 moves horizontally along the heat dissipation pipe, it should be noted that by setting the second gear 16, the one-way bearing 17, the reciprocating screw The rod 18, the screw nut 19, the second hydraulic rod 21 and the grinding ring 22 can drive the first gear 11 to mesh with the second gear 16 through the reverse driving motor 9, so that the reciprocating screw 18 rotates and drives the screw nut 19 to move, and drives the grinding ring 22 to move at the same time, so as to avoid blocking the high-frequency induction coil 6 during welding. The grinding ring 22 is driven downward by the second hydraulic rod 21 to facilitate the grinding ring 22 to fit closely to the welding position and grind its welding slag. By setting the one-way bearing 17, it has the function of preventing reverse movement. When the first gear 11 rotates forward and meshes with the second gear 16, under the action of the one-way bearing 17, the second gear 16 will not drive the reciprocating screw 18 to rotate, so as to avoid driving the grinding ring 22 to move when the heat dissipation pipe is rotated and welded. When the first gear 11 rotates reversely and meshes with the second gear 16, the second gear 16 rotates to drive the reciprocating screw 18 to rotate, and drives the grinding ring 22 to move the welding position for grinding.

[0042] The flux spraying assembly includes a support shaft 24 that rotates on the side wall of the first mounting seat 12, and the support shaft 24 is coaxially sleeved with a third gear 25, and the third gear 25 is meshed with the first gear 11. The side surface of the third gear 25 is fixedly connected with a protruding rod 26, and the top of the protruding rod 26 is hinged with a connecting rod 27, and the end of the connecting rod 27 away from the protruding rod 26 is hinged with a connecting block 28, and the end of the connecting block 28 away from the connecting rod 27 is fixedly connected with a piston rod 29, and the front end of the movable plate 8 is fixedly connected with a first fixed block 30, and the side wall of the first fixed block 30 is connected with a first connecting pipe 31, and the first connecting pipe 31 is provided with an air outlet 32, and the piston rod 29 is slidably connected with the first connecting pipe 31. It should be noted that the injection A one-way valve is provided in the injection tube 37, and the protruding rod 26 is set at an eccentric position of the third gear 25. Therefore, when the third gear 25 rotates, the protruding rod 26 and the connecting rod 27 on its top are driven to rotate around the third gear 25, and the piston rod 29 on its top also moves back and forth in the first connecting tube 31. When the piston rod 29 moves back and forth, the air in the second connecting tube 35 is pushed into the injection tube 37 through the air supply pipe 36. The flux also flows into the nozzle 39 and is sprayed out from the nozzle 40. Such reciprocating motion makes the flux in the injection tube 37 indirectly spray on the rotating heat dissipation pipe, ensuring that each part to be welded can be fully and evenly sprayed with the flux.

[0043] Two blocks 34 are fixedly connected to the top surface of the support plate 33, and an air pipe 36 is fixedly connected in the middle of the two blocks 34. One end of the air pipe 36 is connected to a second connecting pipe 35. The diameter of the second connecting pipe 35 is larger than the diameter of the first connecting pipe 31. It should be noted that when the first connecting pipe 31 pushes the movable plate 8 to move through the first hydraulic rod 7, its top is inserted into the second connecting pipe 35. At this time, the end of the second connecting pipe 35 is just closely adjacent to the air outlet 32, ensuring that when the piston rod 29 is reset, the air accumulated inside the second connecting pipe 35 can be effectively discharged through the air outlet 32.

[0044] The other end of the air supply pipe 36 is connected to an injection pipe 37, which has an injection port 38 for injecting flux. The front end of the injection pipe 37 is connected to a nozzle 39, and a clamping plate 3901 is fixedly connected to the inside of the nozzle 39. A second spring 3902 is fixedly connected to the side wall of the clamping plate 3901, and a baffle 3903 is fixedly connected to the end of the second spring 3902 away from the clamping plate 3901. The baffle 3903 is as to the front end of the injection pipe 37. It should be noted that by setting the second spring 3902 and the baffle 3903, the flux moves the baffle 3903 backward and squeezes the second spring 3902 during the pushing process. When the flux is stationary in the flux tube, the second spring 3902 drives the baffle 3903 to block the outlet of the injection pipe 37 to prevent the flux in the injection pipe 37 from flowing into the nozzle 39 when not in use.

[0045] A nozzle 40 is installed at the bottom end of the nozzle 39, a second fixing block 41 is fixedly connected to the top of the support plate 33, and a brush 42 is installed at the front end of the second fixing block 41. It should be noted that the flux sprayed on the heat dissipation pipe can be evenly applied through the brush 42.

[0046] First hydraulic rods 7 are symmetrically arranged on both sides above the workbench 1 , and the first hydraulic rods 7 are fixedly connected to the moving plate 8 .

[0047] In the present invention, first, the heat dissipation pipe to be welded is embedded in the clamp ring 15. During the placement process, the heat dissipation pipe drives the upper and lower clamp rings 15 to move simultaneously, and squeezes the first spring 14 to deform it. After the heat dissipation pipe is placed, the clamp ring 15 tightly clamps the heat dissipation pipe by the reset force of the first spring 14, and firmly locks it in the U-shaped plate 13. Then, the first hydraulic rod 7 is started to push the moving plate 8 to slide smoothly along the slide groove on the workbench 1. As the moving plate 8 moves, the first connecting pipe 31 is accurately connected to the second connecting pipe 35, and at the same time, the heat dissipation pipe is also moved to the bottom of the nozzle 39.

[0048] At this time, the forward starting motor 9 drives the rotating shaft 10 to rotate. When the rotating shaft 10 rotates, the U-shaped plate 13 at the end is driven to rotate, and the heat dissipation pipe fixed in the U-shaped plate 13 also rotates accordingly. When the rotating shaft 10 rotates, the first gear 11 on its surface engages with the third gear 25, and the third gear 25 rotates under force, and drives the convex rod 26 at the front end to rotate synchronously. The connecting rod 27 at the top also rotates accordingly, and drives the piston rod 29 to reciprocate in the first connecting tube 31 through the connecting block 28.

[0049] When the piston rod 29 slides forward, the air in the first connecting pipe 31 is transported to the second connecting pipe 35, and the flux is pushed from the injection pipe 37 to the nozzle 39 through the air delivery pipe 36. When the piston rod 29 moves backward, the air in the second connecting pipe 35 is discharged through the air outlet 32. During the advancement process, the flux contacts the baffle 3903 in the nozzle 39 and pushes the baffle 3903 backward, compressing the second spring 3902. Subsequently, the flux flows into the nozzle 39, and then the nozzle 40 at the bottom of the nozzle 39 sprays the rotating heat dissipation pipe, and the flux is evenly covered on the surface of the heat dissipation pipe through the brush 42.

[0050] After the coating is completed, the first hydraulic rod 7 is started again to drive the movable plate 8 to reset and move under the high-frequency induction coil 6. Then, the electric telescopic rod 3 is started to drive the high-frequency heating power supply 4 and the high-frequency induction coil 6 to slowly descend, accurately align with the part to be welded, and weld it. When the heat dissipation pipe needs to be rotated and welded, the motor 9 is started again in the forward direction to drive the rotating shaft 10 and the heat dissipation pipe to flip, ensuring that the high-frequency induction coil 6 can evenly cover both sides of the pipe, effectively avoiding the influence of uneven welding temperature on the welding quality.

[0051] After the welding operation is completed, fine welding slag is often left at the welding point of the heat dissipation pipe. At this time, the motor 9 rotates in the opposite direction and drives the first gear 11 to mesh with the second gear. The second gear 16 is rotated under force, and the reciprocating screw 18 is driven to rotate through the transmission of the one-way bearing 17. The screw nut 19 moves horizontally along the screw, and the connecting plate 20 at the top thereof also moves forward smoothly, moving the second hydraulic rod 21 and the grinding ring 22 to the welding point. Start the second hydraulic rod 21 to drive the grinding ring 22 to move down and fit tightly to the welding surface of the heat dissipation pipe. Then, start the motor 9 in the forward direction to drive the rotating shaft 10 to rotate. The U-shaped plate 13 at the top thereof drives the heat dissipation pipe to contact the grinding ring 22, and grinds off the welding slag on the heat dissipation pipe, thereby improving the welding quality.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
