Description

Technical Field

[0001] The present invention relates to the field of welding machines, and particularly to an elbow welding machine and a control system. Background Art

[0002] There are many types of welding machines, including single-point single-function, single-point dual-function, and single-point multi-function (this type of welding machine also has only one welding head, and can perform welding at any angle between 90° and 180° after changing the form of the positioning plate). There are also two-point, three-point, four-point, and even six-point welding machines and four-corner welding machines, etc. Different types of welding machines have different welding functions and working efficiencies.

[0003] Currently, when welding elbows, two pipes are often clamped and butted together by clamping arms. After the end faces of the pipe orifices of the two pipes are butted and adjusted to fit, welding is performed through a welding head. When clamping, the port side or the lateral side of the elbow can be selected. Clamping on the port side is suitable for clamping and butting small elbows. When encountering long and curved elbows, in order to achieve clamping stability, only the lateral side can be selected for clamping. And currently, in some welding equipment during welding and clamping, the two clamping arms are only on the same track, and the distance between the two sides of the clamping arms is adjusted and the clamping position of the elbow is manually adjusted to butt the end faces of the orifices of the two elbows. For example, as described in the elbow welding machine disclosed in the Chinese patent with the patent number CN215091570U, two three-jaw chucks are arranged between the first support and the second support member. When clamping the elbow during welding, the distance between the two is adjusted to clamp and butt the two elbows. When clamping a long elbow on the lateral side and the butting end faces of the orifices of the two elbows are both inclined, simply relying on lateral movement adjustment will limit the butting angle of the clamping, resulting in insufficient butt of the end faces of the orifices of the two elbows after clamping. There will be a phenomenon of stable clamping but insufficient butt or sufficient butt but unstable clamping, which is time-consuming and laborious and reduces the efficiency of welding and clamping. In order to stably butt the end faces of the orifices of the two elbows to achieve better welding, at this time, an elbow welding machine and a control system are urgently needed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an elbow welding machine and a control system to solve the following technical problems:

[0005] How to improve the adaptability and stability of elbow welding.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] An elbow welding machine includes a rotating unit, a moving unit, and a clamping assembly;

[0008] The clamping assembly includes a clamping column and a clamping hand for clamping an elbow;

[0009] The rotation unit is used to drive the clamping column to rotate so as to adjust the clamping angle of the clamping hand.

[0010] The moving unit is used to drive the clamping assembly to move laterally.

[0011] Through the above technical solutions, during welding clamping, the moving unit is adjusted to move the clamping assembly holding the elbow pipe to a suitable lateral position, and then the rotation unit is driven to rotate the clamping assembly holding the elbow pipe to an angle that can better clamp and dock, realizing the adjustment of the clamping distance and rotation angle of the elbow pipe, enabling the elbow pipes on both sides to be better clamped and docked, facilitating better welding, and improving the adaptability and stability of clamping.

[0012] As a further solution of the present utility model: The moving unit includes a welding table, a moving box and a moving table. A moving hole is opened in the middle of the welding table. A moving groove is opened on one side of the moving hole. A rack is arranged on the other side of the moving hole. The rack includes a moving part and a locking part. One side of the moving box is slidably connected to the moving groove. The top of the moving box is fixedly connected to the moving table. The rotation unit is arranged in the middle of the moving table. A power unit is arranged inside the moving box. A regulation unit is arranged at the bottom of the rotation unit.

[0013] Through the above technical solutions, when the regulation unit is pressed, the power unit works and rotates to drive the regulation unit to drive the moving unit to move laterally. When the moving unit moves, the moving box and the moving table are fixedly connected as a whole and move inside the welding table. When the power unit moves and drives the regulation unit to move to the moving part on the rack, the moving unit moves in the moving hole. When the regulation unit is located at the locking part on the rack, the moving unit does not move, achieving the purpose of laterally adjusting the clamping assembly.

[0014] As a further solution of the present utility model: The rotation unit includes a rotating column. One side of the top of the rotating column is fixedly connected to a rotating table. The top of the rotating table is fixedly connected to the clamping assembly. A fixing ring is arranged on the side surface of the rotating column. A rotating groove matching the fixing ring is opened in the middle of the rotating column. The fixing ring is slidably connected to the rotating groove. Internal teeth are arranged on the inner wall of the bottom of the rotating column.

[0015] Through the above technical solutions, when it is necessary to rotate and adjust the clamping angle, the regulation unit is pulled upward. The upper regulation teeth in the regulation unit are engaged with the internal teeth, so that the power unit drives the regulation unit to rotate. The regulation unit rotates to drive the rotating column to rotate. The rotating column rotates on the moving table through the fixing rings fixed around it. When the rotating column rotates, it will drive the rotating table on one side of it to rotate, enabling the clamping assembly to rotate 360 degrees on the rotating table, realizing the adjustment of the clamping angle and facilitating the adjustment of the welding angle after clamping the elbow pipe.

[0016] As a further solution of the present utility model: The control unit includes a lower control gear, a control column and two locking units. The bottom of the control column is fixedly connected to the lower control gear. A rotating ring is rotatably connected to the middle of the control column. A pressing rod is rotatably connected to the top of the control column. Locking units are symmetrically and rotatably arranged on both sides of the rotating ring. An upper control gear is arranged on the control column above the rotating ring. The upper control gear is meshed and connected to the internal gear. The upper control gear and the lower control gear are respectively in transmission connection with the power unit.

[0017] Through the above technical solution, the control unit is used to control the work of the selection moving unit or the rotating unit to adjust the lateral movement or rotation of the clamping assembly. When pressing down the pressing rod, the pressing rod presses the control column, so that the lower control gear is in transmission connection with the power unit. At this time, the upper control gear idles between the power unit and the internal gear, and the locking unit moves downward to lock the rotating unit, so that the rotating column is fixed. The lower control gear moves on the rack under the meshing drive of the power unit, thereby driving the entire moving unit to move; when pulling up the control unit, the control column is pulled so that the lower control column is in transmission connection with the power unit. At this time, the lower control gear idles between the upper and lower power teeth in the power unit, and the upper control gear is in meshing transmission connection with the internal gear, so that the rotating unit rotates, thereby driving the clamping assembly to rotate, realizing the adjustment of the clamping distance and angle, and enabling the bent pipe to be welded better.

[0018] As a further solution of the present utility model: The locking unit includes a locking rod, a locking block and a locking groove. The bottom of the locking rod is rotatably connected to the rotating ring. A sliding hole is opened at the bottom of the locking groove. The top of the locking rod passes through the sliding hole and is fixedly connected to the bottom of the locking block. The bottom of the locking block is slidably connected to the locking groove. Elastic rubber is arranged on one side of the two locking blocks facing each other.

[0019] Through the above technical solution, the locking unit is used to lock the rotating unit when the control unit is pressed and moved downward, so as to prevent the rotating unit from being accidentally touched and causing the movement of its adjusted position when adjusting the moving unit. When the moving column moves downward to adjust the moving unit, the rotating ring moves downward following the adjusting column, and the locking rods on both sides drive the locking blocks to move in the locking groove towards the direction of the rotating column. When the control unit moves downward to above the lower power gear and has not engaged yet, the elastic rubber in the locking unit has squeezed and locked the rotating column. When the control unit is further pressed downward until the lower control gear and the lower power gear are fully engaged, at this time the elastic rubber further locks the rotating column. When the control unit is pulled upward, the control column drives the rotating ring to move upward, and the locking blocks on both sides move away from the rotating column, unlocking the fixation of the rotating unit, so as to realize the rotational adjustment of the rotating unit, avoiding the change of the position of the rotating unit after being accidentally touched, and thus eliminating the need to adjust its position again, improving the adjustment efficiency.

[0020] As a further solution of the present utility model: The power unit includes a power shaft, a rotating motor is arranged at the bottom of the power shaft, an upper power gear is arranged at the top of the power shaft, and a lower power gear is arranged in the middle of the power shaft.

[0021] Through the above technical solution, the power unit drives the power shaft to rotate through the rotating motor, so that the rotating shaft drives the upper power gear and the lower power gear to rotate together, realizing that the power unit can be selected and controlled by the control unit during the rotation process, so that the lateral movement or rotation of the clamping assembly can adjust and select a convenient clamping angle for better welding.

[0022] As a further solution of the present utility model: It includes:

[0023] A control unit for controlling the adjustment of the rotating unit and the moving unit;

[0024] A power unit for providing adjustment power to the control unit;

[0025] A control module for monitoring and judging whether the control unit is adjusted to determine whether the power unit performs power output;

[0026] The control module includes a pressure sensor, a ranging module and a processing module. The ranging module is facing the junction of the power unit and the control unit. A number of infrared ranging sensors are equidistantly arranged on one side of the ranging module facing the power unit. The pressure sensor is arranged on the top of the rotating unit. The control system controls whether the power unit works according to the feedback of the pressure sensor and the infrared ranging sensors;

[0027] When the control module detects that the regulation unit is being adjusted, the power unit stops power output. At this time, move the regulation unit up and down to select the adjustment of the moving unit or the rotating unit. After the movement, the control module controls the power unit to work again to adjust the clamping distance and angle of the clamping assembly.

[0028] Through the above technical solution, the pressure sensor is arranged at the top of the pressing rod in the rotating unit. When pressing and pulling the top of the pressing rod, the pressure information will be detected and sent to the control system to indicate that the regulation unit is about to be adjusted. The ranging module is arranged between the upper and lower power gears and its length is exactly equal to the length between them. A number of infrared ranging sensors are arranged on the ranging module to detect the position of the lower regulation gear. When the pressure sensor detects pressure, the control system stops the power output of the power unit. When it is detected that the pressure of the pressure sensor disappears and at the same time it is detected that the distances detected by a number of infrared ranging sensors on the ranging module are different, the control system controls the power unit to output power again, otherwise the control system stops the power output of the power unit, realizing the convenient control of the welding clamping angle and distance by intelligently controlling the power output of the power unit.

[0029] The beneficial effects of the present invention:

[0030] 1. The clamping assembly on the left is responsible for longitudinal and vertical movement clamping, and the clamping assembly on the right is responsible for horizontal and rotational adjustment of the clamping. When clamping and docking, after adjusting the right clamping assembly to the appropriate position, then adjust the left clamping assembly to dock the cross-section of the elbow pipe orifice. Setting the clamping assembly on the right avoids the situation that when the left clamping hand uses a cylinder to drive and extend close to the right clamping assembly, the structural strength requirement for the cylinder output rod is relatively high, which may cause damage to the cylinder output rod after long-term clamping. After the right clamping assembly clamps the elbow pipe and then moves and adjusts as a whole, the clamping weight-bearing capacity of the elbow pipe is stronger, the clamping is more stable, and the welding quality is improved;

[0031] 2. When horizontally adjusting the clamping assembly, the entire moving box can move horizontally by pressing down the regulation unit. When it is necessary to adjust the rotation angle of the clamping assembly, pull up the regulation unit so that the regulation unit can drive the rotating unit to rotate, thereby enabling the clamping assembly to rotate. The control module is used to control whether the power unit rotates to facilitate the adjustment of the moving unit and the rotating unit, realizing the adjustment of the angle and distance of the clamping assembly, so that when welding and clamping, the elbow pipe can be clamped and rotated in different directions to facilitate the welding of the elbow pipe; through the setting of the locking unit, when the regulation unit is regulated to move the moving unit, the rotating unit is locked and will not be accidentally touched and move, thus changing the adjusted rotation angle, improving the efficiency of clamping adjustment;

[0032] 3. By means of the provided control module, when adjusting the regulation unit, the power unit can automatically stop power output, which facilitates the regulation of the regulation unit. After the regulation unit is adjusted properly, the power is automatically restored to adjust the clamping angle and distance. When there is no need to adjust the clamping angle and distance, the power unit does not output power, which saves the power of the rotating motor and avoids waste of power.

[0033] Of course, when implementing any product of the present invention, it is not necessarily required to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The clamping assembly 6 includes a clamping column 62 and a clamping hand 61 for clamping the elbow pipe;

[0044] The rotating unit 1 is used to drive the clamping column 62 to rotate to adjust the clamping angle of the clamping hand 61;

[0045] The moving unit 2 is used to drive the clamping assembly 6 to move horizontally.

[0046] During welding and clamping, by adjusting the moving unit 2, the clamping assembly 6 clamps the elbow pipe and moves it to a suitable horizontal position, and then by driving the rotating unit 1, the clamping assembly 6 clamps the elbow pipe and rotates it to an angle that can be better clamped and docked, realizing the adjustment of the clamping distance and rotation angle of the elbow pipe, enabling the elbow pipes on both sides to be better clamped and docked, facilitating better welding, and improving the adaptability and stability of clamping.

[0047] The moving unit 2 includes a welding table 21, a moving box 22, and a moving table 23. A moving hole 24 is opened in the middle of the welding table 21. A moving groove 25 is opened on one side of the moving hole 24. A rack 26 is provided on the other side of the moving hole 24. The rack 26 includes a moving part 261 and a locking part 262. One side of the moving box 22 is slidably connected to the moving groove 25. The top of the moving box 22 is fixedly connected to the moving table 23. The rotating unit 1 is arranged in the middle of the moving table 23. A power unit 4 is arranged inside the moving box 22. A control unit 3 is arranged at the bottom of the rotating unit 1.

[0048] When the control unit 3 is pressed, the power unit 4 works and rotates to drive the control unit 3, which in turn drives the moving unit 2 to move horizontally. When the moving unit 2 moves, the moving box 22 and the moving table 23 are fixedly connected as a whole and move inside the welding table 21. When the power unit 4 moves and drives the control unit 3 to move onto the moving part 261 of the rack 26, the moving unit 2 moves inside the moving hole 24. When the control unit 3 is located at the locking part 262 of the rack 26, the moving unit 2 does not move, achieving the purpose of horizontally adjusting the clamping assembly 6.

[0049] The rotating unit 1 includes a rotating column 11, a rotating table 12 is fixedly connected to one side of the top of the rotating column 11, the top of the rotating table 12 is fixedly connected to the clamping assembly 6, a fixing ring 13 is arranged on the side of the rotating column 11, a rotating groove 14 matching the fixing ring 13 is opened in the middle of the rotating column 11, the fixing ring 13 is slidably connected to the rotating groove 14, and an inner wall at the bottom of the rotating column 11 is provided with internal teeth 15.

[0050] When it is necessary to rotate and adjust the clamping angle, the regulating unit 3 is pulled upward, and the upper regulating teeth 36 in the regulating unit 3 engage with the inner teeth 15, so that the power unit 4 drives the regulating unit 3 to rotate, and the rotation of the regulating unit 3 drives the rotating column 11 to rotate. The rotating column 11 rotates on the moving platform 23 through the fixed rings 13 fixed around it. When the rotating column 11 rotates, it will also drive the rotating platform 12 on one side to rotate, so that the clamping assembly 6 can achieve 360-degree rotation on the rotating platform 12, thereby realizing the adjustment of the clamping angle and facilitating the adjustment of the welding angle after the bent pipe is clamped.

[0051] The regulating unit 3 includes a lower regulating tooth 31, a regulating column 32 and two locking units 33. The bottom of the regulating column 32 is fixedly connected to the lower regulating tooth 31, the middle of the regulating column 32 is rotatably connected to a rotating ring 34, the top of the regulating column 32 is rotatably connected to a pressing rod 35, and the locking units 33 are symmetrically rotatably arranged on both sides of the rotating ring 34. An upper regulating tooth 36 is arranged on the regulating column 32 at the top of the rotating ring 34, the upper regulating tooth 36 is meshed with the inner tooth 15, and the upper regulating tooth 36 and the lower regulating tooth 31 are respectively connected to the power unit 4 in transmission.

[0052] The regulating unit 3 is used to regulate the operation of the selected moving unit 2 or the rotating unit 1 to adjust the lateral movement or rotation of the clamping assembly 6. When the pressing rod 35 is pressed downward, the pressing rod 35 presses the regulating column 32, so that the lower regulating tooth 31 is connected to the power unit 4 in transmission. At this time, the upper regulating tooth 36 is located between the power unit 4 and the inner tooth 15 for idling, and the locking unit 33 moves downward to lock the rotating unit 1, so that the rotating column 11 is fixed, and the lower regulating tooth 31 moves on the rack 26 under the meshing transmission of the power unit 4, thereby driving the entire moving unit 2 to move; when the regulating unit 3 is pulled upward, the regulating column 32 is pulled so that the lower regulating column 32 is connected to the power unit 4 in transmission. At this time, the lower regulating tooth 31 is located between the upper and lower power teeth 44 in the power unit 4 and idling, and the upper regulating tooth 36 is meshed with the inner tooth 15 for transmission connection so that the rotating unit 1 rotates, thereby driving the clamping assembly 6 to rotate, thereby realizing the adjustment of the clamping distance and angle, so that the bent pipe can be better welded.

[0053] The locking unit 33 includes a locking rod 331, a locking block 332, and a locking groove 333. The bottom of the locking rod 331 is rotatably connected to the rotating ring 34. A sliding hole 334 is formed at the bottom of the locking groove 333. The top of the locking rod 331 passes through the sliding hole 334 and is fixedly connected to the bottom of the locking block 332. The bottom of the locking block 332 is slidably connected to the locking groove 333. An elastic rubber 335 is provided on one side of the two locking blocks 332 facing each other.

[0054] The locking unit 33 is used to lock the rotating unit 1 when the control unit 3 is pressed and moved downward, so as to avoid the movement of the position of the rotating unit 1 after being adjusted due to accidental contact during the adjustment of the moving unit 2. When the moving column moves downward to adjust the moving unit 2, the rotating ring 34 moves downward following the adjusting column. The locking rods 331 on both sides will drive the locking blocks 332 to move in the locking groove 333 towards the direction of the rotating column 11. When the control unit 3 moves downward to above the lower power tooth 44 and has not been meshed yet, the elastic rubber 335 in the locking unit 33 has already squeezed and locked the rotating column 11. When the control unit 3 is further pressed downward until the lower control tooth 31 is fully meshed with the lower power tooth 44, at this time, the elastic rubber 335 further locks the rotating column 11. When the control unit 3 is pulled upward, the control column 32 will drive the rotating ring 34 to move upward, and the locking blocks 332 on both sides will move away from the rotating column 11, unlocking the fixation of the rotating unit 1, thereby realizing the rotational adjustment of the rotating unit 1, avoiding the change of the position of the rotating unit 1 after being accidentally touched, and improving the adjustment efficiency.

[0055] The power unit 4 includes a power shaft 41. A rotating motor 42 is provided at the bottom of the power shaft 41. An upper power tooth 43 is provided at the top of the power shaft 41. A lower power tooth 44 is provided in the middle of the power shaft 41.

[0056] The power unit 4 drives the power shaft 41 to rotate through the rotating motor 42, so that the rotating shaft drives the upper power tooth 43 and the lower power tooth 44 to rotate together, realizing that the power unit 4 can be selected and controlled by the control unit 3 during the rotation process, so that the lateral movement or rotation of the clamping assembly 6 can adjust and select a convenient clamping angle for better welding.

[0057] Including: a control unit 3 for controlling the adjustment of the rotating unit 1 and the moving unit 2;

[0058] A power unit 4 for providing adjustment power to the control unit 3;

[0059] A control module 5 for monitoring and judging whether the control unit 3 is adjusted to determine whether the power unit 4 performs power output;

[0060] The control module 5 includes a pressure sensor 51, a ranging module 52 and a processing module. The ranging module is facing the junction of the power unit 4 and the regulation unit 3. A number of infrared ranging sensors 521 are equidistantly arranged on one side of the ranging module 52 facing the power unit 4. The pressure sensor 51 is arranged on the top of the rotating unit 1. The control system controls whether the power unit 4 works according to the feedback of the pressure sensor 51 and the infrared ranging sensors 521.

[0061] When the control module 5 detects that the regulation unit 3 is adjusted, the power unit 4 stops power output. At this time, move the regulation unit 3 up and down to select and adjust the moving unit 2 or the rotating unit 1. After moving, the control module 5 controls the power unit 4 to work again so as to adjust the clamping distance and angle of the clamping assembly 6.

[0062] The pressure sensor 51 is arranged on the top of the pressing rod 35 in the rotating unit 1. When pressing and pulling the top of the pressing rod 35, the pressure information will be detected and sent to the control system to indicate that the regulation unit 3 is about to be adjusted. The ranging module 52 is arranged between the upper and lower power gears 44 and its length is just equal to the length between them. A number of infrared ranging sensors 521 are arranged on the ranging module 52 to detect the position of the lower regulation gear 31. When it is detected that there is pressure on the pressure sensor 51, the control system stops the power output of the power unit 4. When it is detected that the pressure on the pressure sensor 51 disappears and at the same time it is detected that the distances detected by a number of infrared ranging sensors 521 on the ranging module 52 are different, the control system controls the power unit 4 to output power again, otherwise the control system stops the power output of the power unit 4, realizing the convenient control of the welding clamping angle and distance by intelligently controlling the power output of the power unit 4.

[0063] The clamping hand 61 on the left side of the welding table 21 can move up and down and left and right and the clamping hand 61 can rotate. During work, first adjust the regulation unit 3 to select and regulate the moving unit 2 and the rotating unit 1 respectively so that the clamping assembly 6 on the welding table 21 clamps the elbow pipe on the right side well and adjusts it to a suitable distance and angle. Then adjust the clamping hand 61 on the left side of the welding table 21 so that the clamping hand 61 moves up and down and back and forth to adjust the pipe orifice section of the elbow pipe clamped by the left clamping hand 61 to be aligned with the pipe orifice section of the elbow pipe after being clamped on the right side, so that the two elbow pipes can be better matched and welded, improving the adaptability and stability of the elbow pipe.

[0064] Working principle of the present invention: When the lateral adjustment clamping assembly 6 is adjusted, the entire moving box 22 can move laterally by pressing down the control unit 3. When the control unit 3 is pressed, the power unit 4 rotates to drive the control unit 3, causing it to drive the moving unit 2 to move laterally. When the moving unit 2 moves, the moving box 22 and the moving table 23 are fixedly connected as a whole and move within the welding table 21. The power unit 4 rotates to drive the control unit 3 to move on the rack 26, thereby driving the entire moving unit 2 to move within the moving hole 24, achieving the purpose of laterally adjusting the clamping assembly 6. When it is necessary to rotate and adjust the clamping angle, pull up the control unit 3. The upper control teeth 36 in the control unit 3 mesh with the internal teeth 15, causing the power unit 4 to drive the control unit 3 to rotate. The control unit 3 rotates to drive the rotating column 11 to rotate. The rotating column 11 rotates on the moving table 23 through the fixed rings 13 fixed around it. While the rotating column 11 rotates, it drives the rotating table 12 on one side to rotate, enabling the clamping assembly 6 to rotate 360 degrees on the rotating table 12, achieving the adjustment of the clamping angle and facilitating the adjustment of the welding angle after clamping the bent pipe. The control module 5 is used to control whether the power unit 4 rotates and operates to facilitate the adjustment of the moving unit 2 and the rotating unit 1, achieving the adjustment of the angle and distance of the clamping assembly 6, so that when welding and clamping, the bent pipe can be clamped in different directions to facilitate the welding of the bent pipe.
