Description

Technical Field

[0001] This utility model belongs to the field of automated welding technology, and in particular relates to an automated circumferential welding platform for butt welding of tubular workpieces. Background Technology

[0002] With the rapid adjustment of the energy landscape and the growth in energy demand, coal is playing an increasingly important role in the energy structure. Domestic and international demand for coal mining equipment remains high, leading to the rapid development of the coal mining machinery remanufacturing industry. However, during the repair of hydraulic supports, the tubular cylinder connector seats often require replacement due to weld leakage and cracking. Therefore, the weld quality of cylinder connector seats is particularly important in the design and manufacture of hydraulic supports. Currently, however, the welding of cylinder connector seats is mainly done by manual arc welding, resulting in inconsistent welding quality for each cylinder and requiring a significant amount of time. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide an automated circumferential welding platform for tubular workpieces, which realizes automatic welding, saves time and effort, and improves welding efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automated circumferential welding platform for butt welding of tubular workpieces includes: a first clamping assembly comprising a first driver, a first support, and a first clamping member rotatably connected to the first support, the first clamping member being used to fix one of the tubular workpieces, and the first driver being used to drive the first clamping member to rotate about the axis of the tubular workpiece; a second clamping assembly spaced apart from the first clamping assembly along the axial direction of the tubular workpiece, and comprising a base, a second support, and a second clamping member rotatably connected to the second support, the second clamping member being used to fix another tubular workpiece, and the second support being slidably disposed on the base along the axial direction of the tubular workpiece; and a pushing assembly located on the side of the second clamping assembly opposite to the first clamping assembly, for pushing the second clamping member to move closer to the first clamping member, so that the two tubular workpieces are butt-welded along their respective axial directions.

[0006] Furthermore, the pushing assembly includes a second driver, a push plate, and a push rod. The push plate is located at the output end of the second driver, and the push rod is located on the side of the push plate facing the second clamping assembly. The second driver is used to drive the push rod to push the second clamping member to move along the axial direction of the tubular workpiece.

[0007] Furthermore, the actuating component also includes a support, on which the second driver is disposed.

[0008] Furthermore, the second clamping assembly also includes a guide rail and a slider. The guide rail is disposed on the base and extends along the axial direction of the tubular workpiece. The slider is slidably disposed on the guide rail, and the second support is disposed on the slider.

[0009] Furthermore, the second clamping assembly includes an operating member, which is movably disposed on the base and has one end abutting against the second support. When the operating member is moved, it can push the second support to move closer to the first clamping member.

[0010] Furthermore, the base is provided with a threaded hole, and the operating member is screwed into the threaded hole and abuts against the second support.

[0011] Furthermore, the first clamping assembly also includes a driving wheel and a driven wheel that cooperate with each other. The driven wheel is located at the end of the first clamping member away from the second clamping member, and the driving wheel is located at the output end of the first driver.

[0012] Furthermore, it also includes a lifting assembly, wherein the first clamping assembly is disposed on the lifting assembly, and the lifting assembly is used to lift the first clamping member to the same height as the second clamping member.

[0013] Furthermore, it also includes a control platform, to which the first driver, the second driver, and the actuation component are all electrically connected.

[0014] This utility model has the following beneficial effects:

[0015] (1) During the welding process, two tubular workpieces can be fixed to the first clamping member and the second clamping member respectively; then, by pushing the component, the second support is moved along the axial direction of the tubular workpiece, so that the second clamping member moves closer to the first clamping member, thereby making the two tubular workpieces dock along their respective axial directions; then, by driving the first driver, the first clamping member is rotated around the axis of the tubular workpiece, so that the two docked tubular workpieces rotate synchronously, which facilitates welding the gap between the two tubular workpieces. This design realizes automatic welding, saves time and effort, and improves welding efficiency.

[0016] (2) The second pushing component is designed as a second driver, a push plate and a push rod, so that the pushing force of the second driver can be transmitted to the second support through the push plate and the push rod, ensuring that the second clamping part moves stably along the axial direction of the tubular workpiece and improving the stability of welding.

[0017] (3) An operating component is installed on the base. In case of a malfunction in the push assembly, the operator can manually push the second support along the axis of the tubular workpiece using the operating component. This ensures that the second support can move smoothly even if the push assembly malfunctions, improving the operability of the welding platform. At the same time, the position of the second support can also be adjusted using the operating component to ensure that the second support remains in the same position after each operation.

[0018] (4) Introducing a lifting assembly ensures that the first clamping member and the second clamping member are at the same height, thereby making the two tubular workpieces on the same axis, improving the docking accuracy of the two tubular workpieces, which is conducive to improving the welding accuracy.

[0029] In one embodiment, please refer to Figures 1 to 3 This application provides an automated circumferential welding platform for butt welding of tubular workpieces, comprising: a first clamping assembly 10, including a first driver 15, a first support 11, and a first clamping member 12 rotatably connected to the first support 11, the first clamping member 12 being used to fix one of the tubular workpieces 60, and the first driver 15 being used to drive the first clamping member 12 to rotate around the axis of the tubular workpiece 60; a second clamping assembly 20, spaced apart from the first clamping assembly 10 along the axial direction of the tubular workpiece 60, and comprising a base 24, a second support 21, and a second clamping member 22 rotatably connected to the second support 21, the second clamping member 22 being used to fix another tubular workpiece 60, and the second support 21 being slidably disposed on the base 24 along the axial direction of the tubular workpiece 60; and a pushing assembly 30, located on the side of the second clamping assembly 20 opposite to the first clamping assembly 10, for pushing the second clamping member 22 to move closer to the first clamping member 12 so that the two tubular workpieces 60 are butt-welded along their respective axial directions.

[0030] The aforementioned automated circumferential welding platform for tubular workpiece docking allows for the fixing of two tubular workpieces 60 to the first clamping member 12 and the second clamping member 22, respectively, during the welding process. Next, the pushing assembly 30 moves the second support 21 along the axial direction of the tubular workpiece 60, causing the second clamping member 22 to approach the first clamping member 12, thus docking the two tubular workpieces 60 along their respective axial directions. Then, the first driver 15 drives the first clamping member 12 to rotate around the axis of the tubular workpiece 60, causing the two docked tubular workpieces 60 to rotate synchronously, facilitating welding of the gap between the two tubular workpieces 60. This design achieves automated welding, saving time and labor, and improving welding efficiency.

[0031] It should be explained that, in order to ensure that the tubular workpiece 60 is stably fixed on the first clamping member 12 and the second clamping member 22, the end face of the first clamping member 12 may be provided with a plurality of first jaws 121; the end face of the second clamping member 22 may be provided with a plurality of second jaws 221. The first jaws 121 and the second jaws 221 are respectively clamped inside different tubular workpieces 60.

[0032] Meanwhile, in the first clamping assembly 10, the first driver 15 can be a motor. To drive the first clamping member 12 to rotate, the first driver 15 can drive the first clamping member 12 to rotate through a structure such as a gear set, rollers, and belt.

[0033] To drive the second support 21 to move along the axial direction of the tubular workpiece 60, the structure of the push assembly 30 can be designed in various ways, such as, but not limited to, a combination of a cylinder, a hydraulic cylinder, an electric cylinder, a motor, and a transmission mechanism.

[0034] In addition, the tubular workpiece 60 can be part of the structure of the hydraulic cylinder connector seat.

[0035] Further, please refer to Figure 1 The pushing assembly 30 includes a second driver 31, a push plate 32, and a push rod 33. The push plate 32 is located at the output end of the second driver 31, and the push rod 33 is located on the side of the push plate 32 facing the second clamping assembly 20. The second driver 31 drives the push rod 33 to push the second clamping member 22 to move along the axial direction of the tubular workpiece 60. It can be seen that by designing the second pushing assembly 30 as a second driver 31, a push plate 32, and a push rod 33, the pushing force of the second driver 31 can be transmitted to the second support 21 through the push plate 32 and the push rod 33, ensuring that the second clamping member 22 moves stably along the axial direction of the tubular workpiece 60 and improving the stability of welding.

[0036] It should be explained that the second actuator 31 can be, but is not limited to, a cylinder, a hydraulic cylinder, an electric cylinder, etc. Meanwhile, the number of push rods 33 can be one or more. When there are multiple push rods 33, all push rods 33 are distributed at intervals along the circumference of the push plate 32.

[0037] In one embodiment, please refer to Figure 1 The pushing assembly 30 also includes a bracket 34, on which the second driver 31 is mounted. It is understood that the bracket 34 facilitates the raising of the second driver 31, making it easier for the push rod 33 to act on the second support 21, driving the second clamping member 22 to move closer to or away from the first clamping member 12.

[0038] Optionally, the second driver 31 can be connected to the bracket 34 by, but is not limited to, bolt connection, snap-fit, welding, etc.

[0039] In one embodiment, please refer to Figure 3 The second clamping assembly 20 also includes a guide rail 25 and a slider 23. The guide rail 25 is located on the base 24 and extends along the axial direction of the tubular workpiece 60. The slider 23 is slidably mounted on the guide rail 25, and the second support 21 is mounted on the slider 23. It can be seen that the cooperation between the guide rail 25 and the slider 23 ensures the smooth movement of the second clamping component 22, improves the stable docking of the tubular workpiece 60, and helps to improve welding accuracy.

[0040] It should be explained that the number of guide rails 25 can be one or two. When there are two guide rails 25, the two guide rails 25 are arranged side by side and spaced apart along the direction perpendicular to the axis of the tube.

[0041] In one embodiment, please refer to Figure 3 The second clamping assembly 20 includes an operating member 26, which is movably mounted on the base 24, with one end abutting against the second support 21. When the operating member 26 moves, it can push the second support 21 closer to the first clamping member 12. Therefore, by installing the operating member 26 on the base 24, if the pushing assembly 30 malfunctions, the operator can manually push the second support 21 along the axis of the tubular workpiece 60 using the operating member 26. This ensures that even if the pushing assembly 30 malfunctions, the second support 21 can still move smoothly, improving the operability of the welding platform. Simultaneously, the position of the second support 21 can be adjusted using the operating member 26, ensuring that the second support 21 remains in the same position after each operation.

[0042] Further, please refer to Figure 3 The base 24 has a threaded hole 241, and the operating member 26 is screwed into the threaded hole 241 and abuts against the second support 21. It can be seen that by rotating the operating member 26, the thread force is used to move the operating member 26 along the axial direction, thereby pushing the second support 21 to move.

[0043] In one embodiment, please refer to Figure 2The first clamping assembly 10 also includes a driving wheel 14 and a driven wheel 13 that cooperate with each other. The driven wheel 13 is located at the end of the first clamping member 12 away from the second clamping member 22, and the driving wheel 14 is located at the output end of the first driver 15.

[0044] The driving wheel 14 and the driven wheel 13 can be connected by a belt, chain, or other structure to transmit rotational force. A speed reducer can also be installed between the driving wheel 14 and the first driver 15.

[0045] In one embodiment, please refer to Figure 2 It also includes a lifting assembly 40, with a first clamping assembly 10 disposed on the lifting assembly 40. The lifting assembly 40 is used to lift the first clamping member 12 to the same height as the second clamping member 22. It can be seen that by introducing the lifting assembly 40, the first clamping member 12 and the second clamping member 22 are kept at the same height, thereby making the two tubular workpieces 60 lie on the same axis, improving the docking accuracy of the two tubular workpieces 60, and thus helping to improve the welding accuracy.

[0046] It should be explained that the lifting assembly 40 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder; it can also be a combination of a motor and a lead screw mechanism, or a combination of a motor and a gear and rack mechanism, etc. Of course, it can also include intersecting links, with the first clamping assembly 10 located at the ends of the two links.

[0047] In one embodiment, please refer to Figure 1 It also includes a control platform 50, and the first driver 15, the second driver 31 and the push assembly 30 are all electrically connected to the control platform 50.

[0048] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
