Technical Field

[0017] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0018] In addition, in the application, the terms "first", "second" and other similar terms are not intended to imply any order, quantity or importance, but are only used to distinguish different elements. The terms "upper", "lower", "left", "right" and other similar terms are only the positional relationships in the drawings.
[0019] As Figure 1 shown, an embodiment of the present application provides a welding device for a tube, including: a base 1, a suspension module 2, a power module 3, a pull rod 4, a detection module 5 and a welding torch module 6. Among them, the welding torch module is installed on the pull rod 4, the pull rod 4 is inserted into the suspension module 2, the pull rod 4 can rotate and the pull rod 4 can slide along its axis. In this way, the welding torch module 6 can be driven to rotate by the pull rod 4 to realize the welding of the annular surface. On the other hand, a positioning rod 7 is fixedly connected to one side of the suspension module 2, and the detection module 5 is installed on the positioning rod 7. The detection module 5 is used to detect the inner diameter of the tube to be welded and position the pull rod 4 to ensure that the pull rod 4 is coaxial with the tube to be welded. The suspension module 2 is used to keep the pull rod 4 in a horizontal state and drive the pull rod 4 to lift and lower. The power module 3 is used to output power to the pull rod 4; the suspension module 2 and the power module 3 are both installed on the base 1.
[0020] Specifically: As Figure 2 shown, in an embodiment of the present application, the suspension module 2 includes: a support plate 21, a link A 23, a link B 24, a guide rail A 25, a guide rail B 26, a slider 27 and a power cylinder B 29. Among them, a through hole is provided in the middle of the support plate 21 for accommodating the pull rod 4; the link A 23 and the link B 24 are cross - arranged and are rotatably connected at the central position; the top of the link A 23 is rotatably connected to the support plate 21, and the bottom of the link B 24 is rotatably connected to the base 1; a guide rail B 26 is installed on the base 1, and a guide rail A 25 is installed at the bottom of the support plate 21; sliders 27 are provided in both the guide rail A 25 and the guide rail B 26. The top of the link B 24 is rotatably connected to the slider 27 in the guide rail A 25, and the bottom of the link A 23 is rotatably connected to the slider 27 in the guide rail B 26. In this way, only by moving the position of the slider 27 can the support plate 21 be raised or lowered, and the support plate 21 can always be kept parallel to the base 1, so that the support plate 21 is always kept in a horizontal state.
[0021] On the other hand, as Figure 2As shown, in an embodiment of the present application, a power cylinder B29 is provided on the right side of the guide rail B26. The telescopic rod of the power cylinder B29 is fixedly connected to the slider 27. In this way, the power cylinder B29 can be used to push the slider 27 to adjust the height position of the support plate 21. A limiting frame 28 is provided on the right side of the support plate 21, and a sliding block that can cooperate with the limiting frame 28 is provided on the end surface of the support plate 21. In this way, the position of the support plate 21 can be further restricted, making the entire device more stable.
[0022] As Figure 3 shown, in an embodiment of the present application, the detection module 5 includes: a curved rod 51, a rotating block 52, a sliding groove 53, a pulley 54, a limiting rod 55, and a pushing block 56. The pushing block 56 is sleeved on the positioning rod 7, and the pushing block 56 can move along the axial direction of the positioning rod 7. There are two curved rods 51, and the two curved rods 51 are symmetrically arranged along the horizontal central plane of the pushing block 56. One end of the curved rod 51 is rotatably connected to the pushing block 56, and a rotating block 52 is installed at the other end of the curved rod 51. A sliding groove 53 is opened in the middle of the curved rod 51, and a pulley 54 is provided in the sliding groove 53. The pulley 54 is rotatably installed on the limiting rod 55, and the limiting rod 55 is fixedly connected to the positioning rod 7. In this way, pushing the pushing block 56 along the axial direction of the positioning rod 7 can drive the two rotating blocks 52 away from or close to the positioning rod 7. When the two rotating blocks 52 are located inside the welding tube, push the pushing block 56 to the left to make the two rotating blocks 52 away from the positioning rod 7. Since the positioning rod 7 and the tube are not coaxial at this time, one of the rotating blocks 52 will surely contact the inner wall of the tube first. At this time, the position of the positioning rod 7 can be adjusted through the suspension module 2 to make the rotating block 52 away from the inner wall of the tube until both rotating blocks 52 contact the inner wall of the tube. At this time, the pull rod 4 must be coaxial with the tube.
[0023] In an embodiment of the present application, to further improve the coaxiality of the pull rod 4 and the tube, a pressure sensor is also installed in the detection module 5, and the installation position is in the gap between the pulley 54 and the sliding groove 53. In this way, the coaxiality of the pull rod 4 and the tube can be judged by comparing the pressure between the pulley 54 and the sliding groove 53.
[0024] On the other hand, as Figure 2 shown, in an embodiment of the present application, a power cylinder A22 is installed on the support plate 21. The telescopic rod of the power cylinder A22 is fixedly connected to the pushing block 56, so as to drive the pushing block 56 to move through the power cylinder A22.
[0025] As Figure 3As shown, in an embodiment of the present application, the welding torch module 6 includes: a welding torch 61, a motor 62, a linear slide rail 63, and a lead screw 64. The linear slide rail 63 is fixedly connected to 4. The lead screw 64 is installed inside the linear slide rail 63. A nut is fixedly installed on the welding torch 61, and this nut is in mating connection with the lead screw 64. The motor 62 is installed on the linear slide rail 63, and the output shaft of the motor 62 is connected to the lead screw 64. In this way, the motor 62 can drive the lead screw 64 to rotate, thereby driving the welding torch 61 to move, and thus adjusting the position of the welding torch 61 according to the inner diameter of the tube cylinder to be welded.
[0026] As Figure 4 As shown, in an embodiment of the present application, the power module 3 includes: a frame 31, slot holes 32, a floating wheel A 33, a fixed wheel 34, a floating wheel B 35, a transition wheel 36, and a transmission belt 37. Among them, the frame 31 is fixedly installed on the base 1. The frame 31 is of a shell structure. The floating wheel A 33, the fixed wheel 34, the floating wheel B 35, the transition wheel 36, and the transmission belt 37 are all installed inside the frame 31. Slot holes 32 are provided at the positions corresponding to the floating wheel A 33 and the floating wheel B 35 inside the frame 31. After the floating wheel A 33 and the floating wheel B 35 are installed, they can both move linearly along their corresponding slot holes 32. The floating wheel A 33 is located above the fixed wheel 34, and the floating wheel B 35 is located on one side of the fixed wheel 34. The floating wheel A 33 and the floating wheel B 35 have the same diameter. The transmission belt 37 is sleeved on the floating wheel A 33, the fixed wheel 34, and the floating wheel B 35. The transition wheel 36 is located outside the transmission belt 37 and is used to keep the transmission belt 37 between the floating wheel A 33 and the fixed wheel 34 parallel to the transmission belt 37 between the floating wheel A 33 and the transition wheel 36, and to keep the transmission belt 37 between the floating wheel B 35 and the fixed wheel 34 parallel to the transmission belt 37 between the floating wheel B 35 and the transition wheel 36. In this way, when the position of the floating wheel A 33 changes, by changing the position of the floating wheel B 35, the transmission belt 37 can always be kept in a taut state, so that when 4 moves up and down, it can always maintain the connection with the power module 3.
[0027] As Figure 5 As shown, in an embodiment of the present application, the power module 3 further includes: a cylinder A 38 and a cylinder B 39. The telescopic rod of the cylinder A 38 is rotatably connected to the floating wheel A 33, and the telescopic rod of the cylinder B 39 is rotatably connected to the floating wheel B 35. Moreover, the inside of the cylinder A 38 and the cylinder B 39 is in communication, and the cylinder A 38 and the cylinder B 39 have the same specifications. In this way, when the floating wheel A 33 undergoes displacement, the floating wheel B 35 can move synchronously, and the displacement distances of the floating wheel A 33 and the floating wheel B 35 are the same.
[0028] As Figure 6As shown in the figure, in an embodiment of the present application, the floating wheel A33 includes a transmission wheel 331 and a sleeve 332. Among them, a spline groove is provided inside the transmission wheel 331, and a spline matching with the spline groove is provided on the surface of the pull rod 4. In this way, when the pull rod 4 moves axially, the connection between the pull rod 4 and the transmission wheel 331 is still maintained; the sleeve 332 is sleeved on the transmission wheel 331, and the transmission wheel 331 is rotatably connected to the sleeve 332, and the sleeve 332 is fixedly connected to the cylinder A38.
[0029] Finally, it should be noted that the above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
